Europe set to miss global heart health targets as obesity skyrockets
According to a paper published in European Heart Journal, the flagship journal of the European Society of Cardiology, the prevalence of obesity in Europe has more than doubled over the past 35 years, with over one in five adults affected.
The third report from the ESC Atlas Project updates and expands upon the previous edition with cardiovascular disease (CVD) statistics to 2019, or the latest available year, for the 57 ESC member countries.
CVD is the most common cause of death in the region, accounting for 45% and 39% of fatalities in women and men, respectively. Unfortunately, the report paints a picture of ageing populations and low birth rates. Between 1970 and 2019 the proportion of individuals aged over 65 years increased from a median 9.2% to 17.2%, and the median age increased from 29.6 to 41.1 years. Alongside this, between 1970 and 2018 fertility rates fell from 2.6 to 1.6, below the average of 2.1 live births per woman needed for population replacement.
Each year, an estimated 48,000 new cases of coronary heart disease occur across Europe due to environmental noise pollution.
Professor Adam Timmis, chair of the report writing team, said, “Sociodemographic and environmental risk factors receive relatively little attention from cardiologists but make a substantial contribution to the risk of CVD. Europe now has top-heavy populations and this will exacerbate the growing burden of CVD. The situation is compounded by increasing urbanisation which threatens heart health due to dirty air, noise, social deprivation and stress. It is estimated that up to 40% of people living in the EU are exposed to noise levels beyond the region’s residential limits.”
According to the World Health Organisation (WHO), noncommunicable diseases kill 41 million people each year, equivalent to 71% of all deaths globally. CVD accounts for most of these deaths (17.9 million annually), followed by cancer (9.3 million). The WHO has set targets for noncommunicable diseases to be met by 2025 but the evidence in today’s report suggests that, across ESC member countries, most goals relating to heart health are unlikely to be achieved. For example, the WHO has called for a halt (with reference to 2010) to the rise in obesity. But between 2010 and 2016, the prevalence of obesity rose from 20.4% to 22.7% in women and from 19.2% to 22.2% in men.
Healthcare professionals will need to be properly trained to deal with the ever-increasing strain of this problem.
Read MoreExperts warn of obesity “pandemic” in Spain
On November 17, 2021, the Spanish Obesity Society (Seedo) launched a campaign asking for a new national multidisciplinary and transversal plan aimed at addressing Spain’s growing obesity epidemic.
According to recent data, more than 60 percent of Spanish adults are considered overweight, 24% of which have obesity and 40 percent of children between 6 and 9 years old are considered overweight, and this is unlikely to have improved during the pandemic. These figures have led specialists to predict what’s been described as a “tsunami of cases” in the coming decades.
“Obesity is a problem that will accompany us in the coming years if strong measures are not taken now,” warned the president of Seedo, Francisco Tinahones. “Strategies must be proposed to prevent and fight obesity because it is not an aesthetic problem but one of the most important diseases facing our health systems.” Tinahones clarified the need for a global plan to tackle obesity, and that the small specific actions taken so far had been merely “drops in the ocean of obesity,” and not useful.
Tinahones proposes that this new strategy include financing from the health system for obesity medication, a tax policy that penalises unhealthy food products and encourages healthy ones, food labelling that clearly reflects how healthy or unhealthy a product is, regulations that prohibit certain advertisements, urban planning that creates spaces for exercise, and the promotion of physical activity.

Over recent decades, alongside economic development, China has undergone a rapid nutrition transition that has resulted in a dramatic acceleration of obesity. Unlike other countries across the world, like the USA and UK, where childhood obesity rates have stabilised, the prevalence in China continues to worsen.
This crisis in China is also unique in terms of how it presents between genders. Dissimilar to other countries, obesity is higher in boys than girls. Boys are almost twice as likely to have obesity. Up until now, there has been limited evidence explaining why these unique sex differences have emerged.
Using a cross-sectional national health survey, Wang and colleagues revealed, as would be expected, that adolescent boys were much more likely to have energy intakes exceeding expectations. Importantly however, it found significantly different self-perceptions by sex, with boys much more likely to underestimate their weight and be satisfied with their current health behaviours.
These weight perceptions were supported by mothers, who were more accurate in predicting their daughter’s weight vs those with a son. Clearly, weight-related beliefs in China have a role to play in the increasing – and widening – rates of obesity in children.
Read MoreThe lasting impact of where we live
The neighbourhoods we live in influence how we behave and ultimately shape our health outcomes. Regardless of how much money an individual earns, if they live in a less-affluent neighbourhood evidence would tell us that they will have poorer health outcomes than if they lived in a more affluent neighbourhood. This effect is particularly strong when looking at obesity and diabetes.
While this has been long understood, little is known about when risk factors emerge in childhood and adulthood in individuals living in socioeconomically different neighbourhoods, and the cumulative effect of disadvantage over childhood. Researchers from Finland set out to answer this question through a population cohort, where participants were measured at repeated intervals for adiposity and behavioural risk factors. By linking postal codes to neighbourhood deprivation scores, researchers assessed the impact of living conditions on diabetes outcomes.
They found that detrimental lifestyle factors by neighbourhood living conditions are present right from childhood and worsen into adulthood. These risk factors accumulate over time to accelerate increased rates of obesity, hypertension and fatty liver by middle age.
