In Colombia, the prevalence of overweight/obesity in children has increased by 26% in the past 5 years. School food environment may be an important contributor and offers opportunities for effective intervention.
We conducted a cross-sectional study among 7- to 14-year-old schoolchildren from 10 schools in Bogotá, Colombia. We examined the school food environment and the relationship of individual-level consumption, and physical activity with overweight/obesity, measured by body mass index and percentage body fat.
Schools with a restaurant/store were characterized as having excessive unhealthy foods. In the sample of 714 schoolchildren, 17.5% were overweight and 10.5% were obese. In multivariate models, boys had significantly increased odds of being overweight/obese (odds ratio [OR]: 1.53; p = .01) as compared to girls. Schoolchildren who consumed a greater number of energy drinks (OR = 1.82; p = .04), and those who spent more than 3 hours per schoolday watching TV (OR = 1.53; p < .01) had increased odds of being overweight/obese.
Approximately 1 in 4 schoolchildren were overweight/obese, with boys, energy drink consumers, and those with low physical activity having increased risk. School-based interventions focused on improving food options and providing health behavior education may be effective to reduce overweight among children in Bogotá and similar settings.
在过去的 5 年中，哥伦比亚儿童超重/肥胖的患病率增加了 26%。学校食物环境可能是一个重要的促成因素，并为有效的干预提供了机会。
我们在哥伦比亚波哥大的 10 所学校中进行了一项 7 至 14 岁学龄儿童的横断面研究。我们检查了学校的食物环境以及个体消费水平与超重/肥胖的关系，超重/肥胖通过体重指数和体脂百分比来衡量。
有餐厅/商店的学校的特点是有过多的不健康食品。在 714 名学龄儿童样本中，17.5%超重，10.5%肥胖。在多变量模型中，与女孩相比，男孩超重/肥胖的几率显著增加（比值比 [OR]：1.53；p = .01）。摄入更多能量饮料的儿童（OR = 1.82；p = .04）和每天在学校看超过 3 小时电视的儿童（OR = 1.53；p < .01）超重/肥胖的几率增加。
大约有 1/4 的学龄儿童超重/肥胖，男孩、能量饮料消费者和体力活动较少的儿童超重/肥胖的风险增加。以改善食物选择和提供健康行为教育为重点的学校干预措施可能对减少波哥大及类似环境中儿童的超重/肥胖有效。
