news Slim chance Failure of anti-obesity program suggests schools unlikely to win battle of the bulge. A year-long, UK-based anti-obesity school program has failed to trim children’s waistlines. A study published in medical journal The BMJ found that the program, which involved increased physical activity, a healthy eating plan and family nutrition workshops, had no real effect on obese six and seven-year-old’s weight, body fat proportions, or even diet or levels of exercise. The testing was rigorous: 1400 children at 54 randomly selected state-run primary schools in western central England participated. The results, therefore, were equally strong, and caused the researchers, led by Professor Peymané Adab at the University of Birmingham’s Institute of Applied Health Research, to extrapolate that school-based anti-obesity programs “are unlikely to halt the childhood obesity epidemic”. Accordingly, other influences, like the home, the community and advertising, may be more effective focal points in tackling childhood obesity. Writing in an accompanying BMJ editorial, Professor Melissa Wake, paediatrician and scientific director at the GenV initiative in Victoria, noted the irony inherent in the study: that the program was delivered in schools and this may have been its downfall. “At least in the United States, children typically gain fitness and lose fat during school terms, with virtually all increases in overweight and obesity occurring over the summer holidays – just when the programs cease to operate,” she said. But Wake thinks the study’s ‘fail’ result is not necessarily a bad thing. “Null trials can help to avoid putting into practice interventions that are ineffective and to decommission those already in place.” She acknowledged, however, that finding effective childhood anti-obesity strategies is extraordinarily difficult, given it is multifactorial.  ■ educationreview.com.au | 7
