Excessive 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. These programs, she noted, have been successful in providing children with physical activities in a more structured setting.
“Summer camps and holiday programs have shown positive results in America and could offer a valuable solution during Australian holidays,” Dr Dumuid said. She emphasised the need for a balance between leisure and physical activity, questioning the reliance on devices and TV for child care at the expense of children’s health.
The study underlines the importance of finding a healthy balance between relaxation and physical activity during school holidays. As societies grapple with increasing rates of childhood obesity and associated health problems, initiatives like summer camps and structured holiday programs could play a pivotal role in ensuring the health and well-being of the younger generation.
