To establish the school eating habits of Mexican children, who are prone to obesity and later to high rates of adult chronic diseases.
Questionnaires for students and parents with staff questionnaires and interviews.
Randomly sampled schools in a socio-economically representative district of Mexico City.
Subjects were 1504 adolescents aged 10-19 years attending schools in Mexico City, 27 teachers and seven headmasters, sampled from both public and private schools and from the full range of socio-economic groups.
Foods brought from home were of a higher nutritional quality than those purchased at school, where purchases were dominated by crisps, soft drinks and other items with high energy density. Girls were more inclined to purchase inappropriately; those from poorer homes purchased less. Private-school students irrespective of socio-economic grade brought more food from home and purchased more expensive food at school. School policies allowed food and drink vendors to market any products within the schools, which benefited financially from these activities.
Current school food policies are conducive to amplifying the current epidemic of obesity and related adult chronic diseases, and need to change.
了解墨西哥儿童的学校饮食习惯，这些儿童容易肥胖，成年后患慢性病的几率也较高。
针对学生和家长的问卷，以及针对教职员工的问卷和访谈。
在墨西哥城一个具有社会经济代表性的地区随机抽样的学校。
1504名年龄在10至19岁之间、就读于墨西哥城学校的青少年，27名教师和7名校长，样本来自公立和私立学校以及社会经济各阶层。
从家里带来的食物营养质量高于在学校购买的食物，学校购买的食物主要是薯片、软饮料和其他能量密度高的食品。女孩更倾向于购买不合适的食物；来自贫困家庭的女孩购买量较少。私立学校的学生，无论社会经济等级如何，从家里带的食物更多，在学校购买的食物也更贵。学校政策允许食品和饮料供应商在学校内推销任何产品，学校从这些活动中获得经济利益。
当前的学校食品政策助长了当前肥胖及相关成人慢性病的流行，需要加以改变。
