Heightened risk of iron deficiency in children with overweight and obesity
A comprehensive study conducted by the University of Leeds’ nutritional scientists has revealed a significant correlation between overweight and obesity in children and young people and an increased risk of iron deficiency. The research, spearheaded by the School of Food Science and Nutrition, involved a meticulous analysis of numerous medical studies across 44 countries, focusing on individuals under 25 years old. These studies assessed levels of essential vitamins and minerals, including iron, in relation to body weight.
The findings indicated that iron deficiency is prevalent among both underweight and overweight youths. Professor Bernadette Moore of the School of Food Science and Nutrition highlighted the broader implications of these findings, suggesting that “Iron status may be the canary in the coalmine, signalling deeper health issues like prolonged inflammation, which is linked to serious conditions including heart disease, diabetes, and fatty liver.”
Unlike deficiencies in zinc and vitamin A, which were primarily found in undernourished children, iron deficiency in overweight children appears to stem from inflammation that disrupts iron absorption. This research, funded by the UK Biotechnology and Biological Sciences Research Council and published in the ‘BMJ Global Health’ journal on 10 May 2024, marks a significant advancement in understanding the nutritional challenges faced by children with obesity.
The impact of iron deficiency on cognitive functions such as attention, concentration, and memory is well-documented, with potential links to conditions like autism and ADHD. This study is pioneering in its focus on the association of iron deficiency with childhood obesity, an area previously unexplored.
Xiaomian Tan, a doctoral researcher at the University, emphasised the importance of this study, stating, “While the link between undernutrition and deficiency of crucial micronutrients in children’s growth is established, the risks posed by obesity—leading to what can be described as a hidden form of malnutrition—are less understood.”
The study also addresses the broader socio-economic implications. Historically, nutrient deficiencies have been associated with hunger, especially in lower- and middle-income countries where they contribute significantly to child mortality. However, the phenomenon of ‘hidden hunger’—nutrient deficiencies in the context of an energy-dense but nutrient-poor diet—is becoming more prevalent in both affluent and developing nations. This is often linked to diets dominated by ultra-processed foods in wealthier countries and limited dietary variety in poorer regions.
The dual burden of malnutrition and overnutrition is particularly pressing in regions like Africa and Asia, which are undergoing rapid economic changes and dietary shifts towards Western high-sugar, high-fat foods. Between 2000 and 2017, the number of overweight children under five years old rose significantly in these continents, alongside an increase in stunting.
Professor Moore also pointed out the alarming trend in the UK, where one in three children by age 11 have overweight or obesity, which compounds the risk of inflammation-driven iron deficiencies. She advocates for increased physical activity and dietary improvements to mitigate these risks.
The call for further research is clear, with an emphasis on the need for more comprehensive studies that address micronutrient deficiencies within the context of the growing global epidemic of obesity, particularly in regions currently lacking detailed data.
Read MoreHealthcare professionals struggle to tackle childhood obesity due to insufficient training
In the face of the escalating childhood obesity crisis, healthcare professionals are encountering significant hurdles, primarily due to a glaring deficiency in training and operational bandwidth. This predicament was illuminated through a study published in the British Journal of General Practice, wherein researchers from the University of Birmingham conducted thorough interviews with healthcare professionals (HCPs) to delve into their experiences with aiding families in the battle against childhood obesity.
One revealing testimony from the study highlighted the practical challenges faced by HCPs: “I had one mum and her child was overweight, but she was a young parent and she actually didn’t know how to cook the dinners and, yeah… we spent a lot of time with her giving her worksheets, how to cook, make potato and beans rather than going to the fish and chip shop.” This account underscores the multifaceted nature of the obesity issue, which extends beyond medical intervention to encompass educational and lifestyle components.
The research unearthed several themes that have frustrated healthcare professionals in their efforts to support families. Among these was the constrained time and training available to HCPs, compounded by a scarcity of specialist services and limited access to routinely collected data on children’s weight. A poignant concern was the risk of eroding trust by broaching the sensitive subject of weight, alongside the need to navigate cultural sensitivities carefully.
Miranda Pallan, Professor of Child and Adolescent Public Health at the University of Birmingham and senior author of the paper, brought to light the pressures faced by healthcare professionals. “This study brings a fresh awareness about the pressures that healthcare professionals face, including the limitations that they face in trying to provide preventative care for young people,” she remarked, emphasising the barriers to offering effective guidance and support.
Echoing these concerns, Dr Ellen Fallows, a sessional GP with a keen interest in childhood obesity, noted a pervasive reluctance to address the root causes, primarily due to a lack of time, knowledge, and incentives among healthcare professionals. “Everyone thinks it is everyone else’s problem, no one is actually talking about the root causes with parents – which is predominantly food quality,” Dr Fallows observed. She advocated for the wider availability of quality training resources as a vital first step in equipping HCPs to tackle this issue.
The study also touched upon the contentious use of BMI centiles for assessing children’s weight issues, revealing a division among healthcare professionals. Some, including doctors and primary care nurses, admitted to being less familiar with BMI centiles and questioned its suitability for younger children. One participant noted, “We used to use the [height and weight] centile charts and actually the BMI will put a lot more children in an overweight category than the centile charts will.”
The collective insights from this study underscore a pressing need for a strategic overhaul in how childhood obesity is approached within the healthcare system. While the direct teaching of nutritious cooking to families might be beyond the scope of HCPs, the findings advocate for an enhanced support framework, enabling practical advice and referrals to specialist services. As childhood obesity continues to pose a serious, multifaceted challenge, the call for a comprehensive strategy that includes better training, resources, and a unified effort to address its root causes has never been more urgent.
Read MoreObesity during youth could double the risk of multiple sclerosis in later life, research suggests
Children grappling with obesity might face a significantly higher likelihood of being diagnosed with multiple sclerosis (MS) in adulthood, according to recent research findings.
Multiple sclerosis is a condition that impacts the brain and spinal cord, leading to a wide array of potential symptoms, including challenges with vision, coordination in the arms or legs, sensation, or balance. As a lifelong affliction, MS can sometimes lead to severe disability.
These insights are set to be shared at the European Congress on Obesity, taking place in Venice this May, and stem from research conducted by the Karolinska Institute in Stockholm.
Prior studies have hinted at a connection between an elevated body mass index (BMI) during adolescence and a heightened risk of MS. However, the majority of these analyses relied on retrospective approaches and self-reported data, which could introduce biases.
The recent investigation aimed to prospectively assess the risk of MS development among a significant cohort of children with obesity in comparison to their counterparts in the broader population. To this end, the researchers turned to the Swedish Childhood Obesity Treatment Register, also known as Boris. This database stands as one of the globe’s most extensive records dedicated to the treatment of childhood obesity.
The team reviewed data pertaining to children between the ages of two and 19 who were enrolled in the registry from 1995 to 2020. This information was then juxtaposed with data from the general population of children.
In total, the study took into account data from over 21,600 children who commenced obesity treatment at an average age of 11, alongside more than 100,000 children without obesity.
Throughout an average tracking period of six years, MS was diagnosed in 28 children from the group with obesity (representing 0.13% of this cohort) and 58 children from the group without obesity (0.06%).
The average age at which MS was diagnosed remained similar across both groups, with diagnoses typically occurring around the age of 23.
While acknowledging certain limitations in their study, the researchers underscored: “Despite the limited follow-up time, our findings accentuate that childhood obesity amplifies the risk of developing early-onset MS by more than double.”
The study’s lead researchers, Associate Professor Emilia Hagman and Professor Claude Marcus, commented: “Obesity during childhood induces a low-grade, yet chronic inflammation, which likely elevates the risk of developing various conditions, including MS.”
They further elucidated that such chronic low-grade inflammation is believed to elevate the risk of other conditions, such as asthma, arthritis, type 1 diabetes, and certain cancers. Notably, they highlighted that weight loss can diminish inflammation, thereby potentially reducing the risk of developing these diseases.
Read MoreVery low calorie diets safe for teens with obesity when monitored by a dietitian, study finds
In recent findings set to be unveiled at the European Congress on Obesity (ECO) in 2024, researchers assert that stringent low-calorie diets, when under the vigilant oversight of seasoned dietitians, hold promise for adolescents grappling with moderate to severe obesity.
The study, originating from Australia, explored the viability and tolerance of very low energy diets (VLEDs) among teenagers, revealing an overall positive reception despite some experiencing adverse effects. VLEDs, characterised by a daily intake of 800 calories or less through specialised meal replacements like bars and shakes, aim to fulfil essential nutrient needs while offering an alternative path to weight loss. This approach is particularly geared towards young individuals who have found little success with traditional diet and exercise regimens, presenting a potential prelude to a more balanced diet without resorting to bariatric surgery.
Historically, the application of VLEDs in youth has been approached with caution due to scant data concerning potential side effects—ranging from headaches and fatigue to muscle cramps and digestive issues—and their impact on overall growth, cardiac health, and psychological well-being. This hesitancy underscores the significance of the study conducted by Dr. Megan Gow and her team at the Children’s Hospital Westmead Clinical School, affiliated with The University of Sydney, Westmead, Australia.
The research delves into the initial phase of the “Fast Track to Health” study, specifically the first four weeks during which participants engaged in a nutritionally balanced VLED to initiate weight loss. The cohort, comprising 141 adolescents aged 13 to 17 years with obesity and at least one obesity-related complication (e.g., hypertension, insulin resistance, or dyslipidemia), was divided to receive either four Optifast meal replacement products daily alongside low carbohydrate vegetables and a teaspoon of vegetable oil or a similar regimen with three meal replacements and one solid meal of lean meat and vegetables.
Support was provided through weekly consultations with a dietitian, with assessments at baseline, weekly intervals, and a comprehensive survey to gauge the diet’s acceptability, detailing aspects the participants found favourable or unfavourable.
Despite prevalent side effects, the adherence rate was notably high, with an average weight loss of 5.5kg observed across participants. The majority reported experiencing multiple side effects, including hunger, fatigue, headaches, and gastrointestinal disturbances, with the incidence peaking in the first week. Interestingly, a correlation was observed between the early onset of side effects and more substantial weight loss, hinting at higher compliance with the dietary restrictions.
Feedback on the VLED’s practicality and enjoyment yielded mixed reviews, with the structured nature and the tangible outcomes of weight loss cited as positives, whereas the restrictive diet and the palatability of meal replacements drew criticism.
The findings advocate for the short-term safety and potential acceptability of VLEDs under professional guidance for adolescents with significant obesity challenges. Dr. Gow emphasises the necessity for further research to pinpoint those who would benefit most from this approach. She advocates for the incorporation of VLEDs into clinical guidelines for managing severe obesity and related health issues in young people, positioning it as a preliminary step before considering medication or surgery.
Adolescents and their guardians are encouraged to consult healthcare professionals to explore suitable treatment avenues for obesity.
This study not only sheds light on the pragmatic aspects of implementing VLEDs among adolescents but also underscores the importance of professional oversight and the need for a broader discourse on obesity management in younger populations.
Read MoreBMI found outdated for childhood obesity measurement in Bristol study
A groundbreaking study hailing from Bristol has shed new light on the efficacy of current methods used to assess childhood obesity, proposing a shift towards a more precise alternative. This research scrutinises the longstanding reliance on Body Mass Index (BMI) for evaluating obesity in children, suggesting that the waist-to-height ratio (WHtR) could serve as a superior metric.
The comprehensive analysis spanned over 15 years and delved into the health metrics of 7,237 children, each nine years of age, revealing significant insights. These findings challenge the existing guidelines that favour BMI as the standard obesity measure, underlining the urgent need for more accurate obesity detection in paediatric health.
Published in the prestigious journal Paediatric Research, this study is a component of the expansive Children of the 90s project, drawing attention to the escalating obesity rates amongst 10 and 11-year-olds in England, a surge notably exacerbated by the Covid pandemic and yet to recede to pre-pandemic figures.
Professor Julian Hamilton-Shield, a consultant paediatrician at the Bristol Royal Hospital for Children and a leading figure in the study, voiced concerns over the increasing prevalence of severe obesity and its complications observed in his weight management clinic. “The uptick in severe obesity levels and its attendant severe complications underscores the necessity for reliable measures that offer a clearer insight into an individual’s health status,” stated Prof Hamilton-Shield.
The research team scrutinised BMI data sourced from the government’s National Child Measurement Programme, which annually assesses approximately a million Year 6 students across England. While BMI has been a cornerstone in determining healthy weight parameters, offering a simple and quick assessment method based on height and weight, its limitations are becoming increasingly apparent. Specifically, BMI fails to account for body frame variations or muscle mass, rendering it an incomplete measure of body fat.
This limitation is particularly poignant when considering that BMI might categorise individuals with significant muscle mass, such as rugby players, as having obesity, highlighting its outdated nature. In contrast, the study, conducted in collaboration with researchers from the University of Bristol, the University of Exeter, and the University of Eastern Finland, advocates for the WHtR as a viable replacement for BMI. This method promises a more accurate assessment of excess fat mass in children and adolescents.
Professor Andrew Agbaje, the lead author of the study, emphasised the practicality and effectiveness of the waist circumference-to-height ratio. “Utilising just a measuring tape, we can accurately identify eight out of ten children who genuinely have obesity. Furthermore, this method allows us to correctly recognise 93 out of 100 individuals who, despite being muscular, would be mistakenly classified as overweight or having obesity by BMI standards,” Prof Agbaje explained.
He further highlighted that unlike BMI, which fluctuates with age and sex, the waist-to-height ratio remains consistent, irrespective of these variables. This finding underscores the potential of WHtR to revolutionise how childhood obesity is measured, offering a more nuanced understanding of body composition and facilitating the identification of true obesity, thus enabling more targeted and effective interventions.
Read MoreStudy highlights higher incidence of musculoskeletal issues in young girls with obesity
Recent research indicates a concerning trend among young girls aged 4 to 11 who are overweight or have obesity, showing they are more frequently visiting GPs for musculoskeletal problems compared to their counterparts of a healthy weight.
The study reveals that girls in their first year of school (reception year) with a Body Mass Index (BMI) classified as overweight have a 24% increased likelihood of attending a GP appointment for a musculoskeletal issue at least once. This probability soars to 67% for girls identified as living with obesity. Furthermore, by the time they reach year 6, girls with obesity are 20% more likely to consult a GP for similar problems. Conversely, boys in the same age bracket with a BMI categorised as underweight were found to be 61% less likely to seek such medical advice compared to their peers of a normal weight.
The most frequently reported problems were related to knee and back pain, as outlined in the results published in the “Archives of Disease in Childhood” journal, focusing on a specific London area.
Nicola Firman, the study’s lead author and a health data scientist at Queen Mary University of London, emphasised the scarcity of longitudinal studies examining the link between obesity and musculoskeletal health outcomes during childhood. Despite a systematic review revealing a general lack of substantial evidence, this study aims to bridge that gap by investigating these health outcomes in an ethnically diverse population within the UK, known for its high rates of childhood obesity and social deprivation.
Among the youngest participants, knee pain was reported by 46% of boys and 41.5% of girls, with these figures slightly decreasing among year 6 students to 40.4% for boys and 36% for girls. In terms of back pain, 22% of reception year boys and a higher 32% of girls experienced this issue, which increased to 30% for boys and an alarming 45% for girls by year 6.
Interestingly, the study noted that reception year girls with obesity were significantly more inclined to consult their GP over musculoskeletal issues than their healthy weight female peers, a trend not observed among boys.
Firman also referenced studies from Spain and the USA, noting an observed rise in back pain incidents among girls, not boys, highlighting the global need for more longitudinal research to fully understand the relationship between childhood obesity and musculoskeletal health.
The research sample included primary school children from four ethnically diverse local authorities in north-east London.
Katharine Jenner, Director of the Obesity Health Alliance, responded to these findings with concern, stressing that primary school-aged children should be enjoying their youth actively rather than facing the physical limitations and pains leading to GP consultations. She criticised the government’s lack of action on its obesity strategy, pointing out that the goal to halve childhood obesity by 2030 is becoming increasingly unattainable without significant policy changes and implementations.
Research indicates higher likelihood of midlife obesity in individuals whose parents had obesity
In the midst of growing concerns regarding global health, a pivotal study poised for presentation at the esteemed European Congress on Obesity (ECO) in Venice, from 12th to 15th May 2024, sheds light on the intergenerational transmission of obesity, revealing profound insights into how parental obesity significantly influences the likelihood of obesity in their offspring during middle age.
This groundbreaking research, led by Mari Mikkelsen from the Department of Community Medicine at UiT Arctic University of Norway in Tromsø, embarks on a novel investigation into the persistence of obesity from one generation to the next, particularly extending beyond adolescence and well into adulthood—a period often overlooked in previous studies. Mikkelsen’s team delved into the intricate relationship between the Body Mass Index (BMI) of parents and their adult children, employing data meticulously gathered from the Tromsø Study, a comprehensive, ongoing population-based health study.
The analysis encompassed 2,068 parent-offspring trios, focusing on individuals aged 40-59 years who participated in the seventh wave (2015-2016) of the Tromsø Study, with their parents’ data drawn from the fourth wave (1994-1995). The findings illuminate a compelling correlation between the BMI of parents in their middle years and that of their children at a similar stage in life, underscoring a pronounced genetic and environmental legacy of obesity.
Specifically, the study reveals that when both parents had a BMI indicating obesity (BMI ≥ 30 kg/m²) during their forties and fifties, their offspring were six times more likely to experience obesity at the same age compared to those whose parents were within a normal weight range (BMI 18.5-24.9 kg/m²). Moreover, the presence of obesity in just one parent still significantly elevated the likelihood of the offspring living with obesity, with the odds being over three times higher.
An intriguing aspect of the research was the quantification of the BMI transmission effect: an offspring’s BMI increased by 0.8 units for each 4-unit rise in the mother’s BMI and by 0.74 units for every 3.1-unit increase in the father’s BMI. These findings persisted even after adjustments for several variables, including the sex, age, education, and physical activity levels of both parents and offspring.
Mikkelsen’s team provides a nuanced understanding of the multifaceted factors contributing to this familial trend in obesity. Genetic predispositions play a crucial role by influencing susceptibility to weight gain and shaping reactions to an increasingly obesogenic environment. Additionally, shared family behaviours concerning diet and exercise, established during childhood and adolescence, may further perpetuate similar BMI statuses within families.
This profound research not only reinforces the enduring impact of familial obesity patterns but also emphasises the critical need for effective obesity prevention and treatment strategies. By highlighting the long-lasting consequences of parental obesity on their children into middle age, the study paves the way for future research aimed at identifying and mitigating the factors responsible for the intergenerational transmission of obesity. In doing so, it offers hope for breaking the cycle of obesity and fostering a healthier future for subsequent generations.
Read MoreAI breakthrough improves eye exam rates in youth with diabetes
In a ground-breaking study conducted by the Johns Hopkins Children’s Center, researchers have demonstrated a significant leap forward in the field of diabetic eye care through the implementation of autonomous artificial intelligence (AI) for eye examinations. This innovative approach has markedly improved the rate of screening completions among children and adolescents with diabetes, thereby offering a promising avenue to combat the incidence of diabetes-related eye diseases (DED), which can lead to blindness if left unchecked.
The study, which has been a focal point of attention in a recent Johns Hopkins news release, utilises a non-intrusive method whereby images of the retina are captured without the necessity for pupil dilation. Following this, AI technology analyses the images to provide instantaneous results, distinguishing this method from traditional screening procedures which often require an additional appointment and dilation of the eyes.
The significance of this research cannot be overstated, especially considering its potential to bridge healthcare disparities. Historically, minority and economically disadvantaged youth, who are at a heightened risk of developing DED, have faced substantial barriers in accessing regular eye screenings. The AI-driven method heralded by this study not only promises to close these care gaps but also to enhance adherence to screening protocols among these populations.
Published in the esteemed journal Nature Communications, the study analysed eye exam completion rates among individuals under 21 years of age suffering from type 1 and type 2 diabetes. Remarkably, it was found that all participants who underwent the AI-based screenings completed their eye assessments, a stark contrast to traditionally lower adherence rates.
Diabetic retinopathy, a condition affecting 4% to 9% of youth with type 1 diabetes and 4% to 15% of those with type 2 diabetes, underscores the urgency for regular screenings. The American Diabetes Association estimates that approximately 238,000 individuals under the age of 20 are living with diagnosed diabetes, making early detection and treatment of eye conditions critical to preventing the advancement of DED.
Despite the general recommendation for annual screenings, traditional methods have seen a participation rate of only 35% to 72% among young diabetic patients, with even lower rates observed in minority and economically disadvantaged groups. Barriers such as confusion over the necessity of screenings, inconvenience, and lack of accessibility have all contributed to this shortfall.
The Johns Hopkins study introduced a novel solution to these challenges by incorporating autonomous AI screening into routine visits to the endocrinologist, thereby eliminating the need for separate appointments and the discomfort of eye dilation. This method, which involves taking four images of the eye to assess for diabetic retinopathy, has not only streamlined the screening process but also facilitated immediate follow-up actions when necessary.
This research initiative enrolled 164 participants from the Johns Hopkins Pediatric Diabetes Center, with a demographic makeup that was both gender and ethnically diverse. The findings revealed a 100% completion rate for eye exams among the group subjected to AI screenings, a significant improvement over traditional methods.
The study’s lead, Dr. Risa Wolf, emphasised the dual benefits of this approach: increased screening rates and the potential to enhance health equity. By making screenings more accessible and convenient, the researchers hope to prevent the progression of diabetic eye disease across all demographics.
However, it is important to note the study’s limitations, including the current FDA approval status of the autonomous AI for individuals under 21 and the potential bias due to some participants’ prior familiarity with AI screenings from a previous study.
Funded by the National Eye Institute of the National Institutes of Health and the Diabetes Research Connection, this study represents a pivotal step forward in diabetic eye care. It not only underscores the transformative potential of AI in healthcare but also highlights the critical need for innovative solutions to improve access and outcomes for vulnerable populations.
Read MoreHealth experts raise alarm over ‘appalling decline’ in UK child health
In a stark warning to the nation, leading health experts have highlighted an ‘appaling decline’ in the health and wellbeing of the UK’s children, attributing this trend to increasing instances of obesity and tooth decay among the youth. The Academy of Medical Sciences has released a report urging immediate intervention to halt the decline of physical and mental health in children under five years of age across Britain.
Professor Helen Minnis, co-chair of the report and a distinguished academic from the University of Glasgow, has painted a grim picture of the current state of child health in the UK. “We are witnessing a disturbing increase in child mortality rates, with the UK lagging in infant survival compared to its peers. A plethora of preventable physical and mental health issues is afflicting our youngest, which demands prompt and decisive action,” Minnis stated.
The report sheds light on alarming statistics, revealing that over 20% of children aged five have either obesity or overweight. Furthermore, tooth decay has emerged as a prevalent concern, affecting one in four children. The financial repercussions of this health crisis are staggering, with the report estimating the cost to exceed £16 billion annually.
A particularly concerning trend noted in the report is the decline in vaccination rates across the UK, which now fall below the safety benchmarks established by the World Health Organization. This decline poses a significant threat to the nation’s capability to fend off future outbreaks of severe childhood illnesses.
This call to action resonates amid a growing chorus among medical professionals advocating for enhanced access to childhood vaccinations and addressing the rising vaccine hesitancy within certain communities.
The report also forecasts that the issue of child health, particularly the increasing rates of obesity and declining stature compared to international standards, will become a focal point in the forthcoming general election.
The Labour Party has pointed fingers at the current government’s policies for exacerbating health issues among children, particularly highlighting tooth decay as the leading cause of hospital admissions for children between six and ten years of age.
“The evidence is unequivocal: we are failing our children. If we do not place the health of infants and young children at the forefront of our priorities, we risk consigning many to a future of diminished health and unfulfilled potential. The moment to act is now,” Professor Minnis stated emphatically.
The Royal College of Paediatrics and Child Health has backed the report’s findings, describing them as “alarming evidence that the UK is failing too many of its children.”
In response, a government spokesperson defended the administration’s track record, highlighting several measures aimed at improving child health. “Significant steps have been taken, including substantial reductions in sugar content in children’s food, investing over £600 million to enhance the quality of children’s sports, and promoting healthy diets among lower-income families through initiatives like Healthy Start,” the spokesperson noted.
Additionally, the government underscored its investment of an extra £2.3 billion annually into mental health services and pointed to a 14% increase in the number of children seen by NHS dentists in the previous year as evidence of its commitment to reversing the decline in child health.
Read MoreStudy finds some 40% of Chinese children face obesity by 2030
A comprehensive study recently unveiled alarming projections that nearly 40% of Chinese children and adolescents are on track to have overweight or obesity by the year 2030 if current upward trends persist. This pressing issue has prompted calls from experts for immediate action to mitigate the looming health crisis, with proposed strategies including the implementation of a 20% levy on sugar-laden beverages.
The research, which was published in The Lancet Regional Health last month and conducted by a collaborative team from the School of Public Health at Peking University and the United Nations Children’s Fund, highlights the swift rise in obesity rates among the youth in China, pinpointing significant consequent health and financial repercussions.
The study’s forecasts paint a grim picture, estimating a staggering lifetime economic toll of 218 trillion yuan (approximately $31.6 trillion) from 2025 to 2092, attributable to the prevailing rates of obesity among children and adolescents in the absence of intervention strategies.
Zhou Maigeng, Deputy Director of the National Center for Chronic and Noncommunicable Disease Control and Prevention at the Chinese Center for Disease Control and Prevention, stressed that the economic strain posed by the increasing prevalence of children with overweight and obesity is often overlooked, as many related health complications have yet to manifest.
Alarm bells have already been sounded by data concerning adult obesity, which forewarns of the annual costs of chronic diseases linked to excess weight reaching 49 billion yuan by 2030, according to Zhou.
The upward trajectory of childhood and adolescent obesity in China has been startling, with prevalence rates soaring from a relatively modest 8.8% in 2000 to an estimated 37.9% in 2020—an increase of 400% over two decades. This surge has not only eclipsed the global average but also surpassed rates observed in certain Western and upper-middle-income nations. Without decisive action, researchers warn that these figures could exceed 60% by 2030.
In response to this growing public health concern, China has initiated several national interventions aimed at curbing the trend, focusing primarily on enhancing nutrition and physical activity within schools. The proposed introduction of a 20% tax on sugar-sweetened beverages, coupled with tighter restrictions on marketing unhealthy food products to children, has been identified as the most effective course of action.
This recommendation aligns with the World Health Organization’s guidance issued in December, urging nations to adopt or amplify existing taxes on sugary drinks as a measure to safeguard public health. The call to action is supported by evidence from countries like Mexico, South Africa, and the United Kingdom, where such fiscal policies have yielded positive outcomes.
Zhang Man, a researcher at Peking University, emphasised the importance of grounding policy decisions in scientific evidence and underscored the need for ongoing monitoring and evaluation of intervention impacts, suggesting adjustments based on observed results to enhance efficacy.
Read MoreCurbing fruit juice intake in childhood may reduce obesity risk, research indicates
Recent research indicates that reducing the consumption of 100% fruit juice in children could be a key strategy in addressing the growing concern of childhood obesity, especially in younger age groups.
Published in the journal JAMA Pediatrics, this study sheds light on a significant issue: children who have overweight or obesity are more likely to maintain this status into adulthood. The researchers, therefore, advocate for limiting fruit juice intake to avoid excess calorie consumption and subsequent weight gain.
A team from the University of Toronto in Canada spearheaded the research, analysing data from 42 previous studies to explore the relationship between drinking 100% fruit juice and weight gain in both children and adults. While the link with adult weight gain requires further exploration, the team observed a definitive correlation between juice consumption and weight gain in children.
The study defined 100% fruit juice as a drink with no added sugar, with a standard serving being 8 ounces. The researchers evaluated data for approximately 46,000 children aged between 1 and 15 years. Their findings pointed to a clear association between each additional serving of 100% fruit juice and an increase in body mass index (BMI), a standard metric for determining overweight and obesity status. The team highlighted that, unlike whole fruits, juice lacks significant fibre, potentially leading to high calorie intake without a corresponding feeling of fullness.
The American Academy of Pediatrics has set guidelines advising against fruit juice for infants under one year and recommending a daily limit of 4 ounces as part of a meal for toddlers and young children. For children aged 1 to 6 years, the intake should not exceed 6 ounces per day.
On its website, the Academy emphasises, “Fruit juice offers no nutritional benefits over whole fruit,” pointing out that whole fruits also contain fibre and other essential nutrients. It advises against giving fruit juice at bedtime and cautions against its use in managing dehydration or diarrhoea.
The urgency of addressing childhood overweight and obesity is underscored by alarming statistics from the U.S., where 1 in 5 children aged 2 to 19 years have obesity. Obesity in childhood carries the risk of serious health issues such as high blood pressure, high cholesterol, type 2 diabetes, asthma, sleep apnea, and joint problems, according to the CDC.
The study observed that children consuming fruit juice gained more weight than those drinking zero-calorie beverages, like water. This weight gain was most pronounced in children aged 8 years and younger when compared to their peers consuming non-caloric drinks.
The types of juice consumed included pomegranate, berry, tart cherry, apple, citrus, and grape, with no noticeable differences in BMI impact based on juice type. The researchers suggested that weight gain could be attributed to the high liquid calorie content in fruit juice and the rapid absorption of fructose, which can affect liver function and cholesterol levels.
In conclusion, the study supports public health recommendations to limit the consumption of 100% fruit juice as a preventative measure against overweight and obesity in children.
Read MoreExcessive school holiday downtime linked to rising health concerns in children
The extended school holidays, a period of relaxation and rest for educators and students alike, may be inadvertently contributing to health issues in children. Recent research highlights a worrying trend of increased weight gain during these leisure times, particularly among children.
In Australia, the prevalence of children and teenagers with overweight or obesity stands at one in four, reflecting a global issue where over 124 million children and adolescents have obesity. These alarming figures have spurred governments, educational institutions, and communities to advocate for enhanced physical activity and healthier eating habits among the younger demographic.
The groundbreaking ‘Life on Holidays‘ study, spearheaded by the University of South Australia’s Alliance for Research in Exercise, Nutrition and Activity team, is the first to explore this phenomenon outside the United States. It specifically examined the impact of holiday periods on children’s fitness levels and body composition.
The study’s findings revealed a concerning pattern: children’s body fat accumulates more rapidly during school holidays than during academic terms. Notably, children in Years 4 and 5 exhibited a decrease in physical activity and an increase in sedentary behaviours during their holidays.
Key observations included children sleeping an average of 12 minutes less, engaging in 12 fewer minutes of physical activity daily, and spending an additional 70 minutes on screens each day during holiday periods. Consequently, there was a marked acceleration in body fat accumulation and a more pronounced decline in aerobic fitness compared to term time.
Professor Tim Olds, lead researcher from UniSA, suggests that promoting physical activities during school holidays could be crucial in combating these negative health trends. He notes that while children and their parents rightly deserve holiday downtime, the lifestyle shift during these periods often negatively impacts children’s health.
“On school holidays, kids are significantly less active than when they’re at school, leading to higher body fat percentages and lower levels of fitness,” Professor Olds remarked. He expressed concern over the rapid rate of weight gain and fitness loss during holidays, pointing out the potential long-term health risks such as cardiovascular disease and Type 2 diabetes.
The study, which spanned two years, focused on children aged 9-10 years and involved over 150 participants. Data were collected at the start and end of Terms 1 and 4 across Grades 4 and 5.
Co-researcher Dr Dot Dumuid highlighted that the unstructured nature of school holidays contributes significantly to these trends. She pointed out that children have unrestricted access to food and are prone to increased screen time due to the lack of structured activities.
Dr Dumuid contrasted this with the structured environment of school days, where meals are planned, and physical education lessons and playtimes are scheduled. She suggested that adopting American-style summer camps and holiday programs could be an effective way to address the issue in Australia.
