Increased understanding of the early determinants of obesity is essential because of the increasing prevalence of obesity in many industrialized countries.
As part of the evaluation of a school-based heart health promotion intervention, we measured height, weight, and triceps skinfold thickness at baseline in 2108 students aged 9-12 years (80.5% of eligible students) in 24 inner-city elementary schools located in multiethnic, low income neighbourhoods in Montreal, Canada. Data on student's socio-demographic and lifestyle characteristics were collected in classroom-administered questionnaires, and parents completed an at-home self-administered questionnaire.
Overall, 35.2% of boys and 33.0% of girls were overweight (> or = 85th age and gender-specific percentiles from NHANES 11, for body mass index and triceps skinfold thickness); 15.1% of boys and 13.3% of girls were obese (> or = 95th age and gender-specific percentiles for body mass index and triceps skinfold thickness). Younger age, having lived all one's life in Canada, and being of European or Central American/Caribbean family origin were independent correlates of obesity in boys. Younger age, ever smoked, mother obese and father obese were independent correlates of obesity in girls. Girls of Asian family origin were protected.
The very high prevalence of overweight students in this low income, multiethnic population suggests an important need for preventive intervention.
鉴于许多工业化国家肥胖症患病率不断上升，加深对肥胖症早期决定因素的了解至关重要。
作为一项基于学校的心脏健康促进干预评估的一部分，我们在加拿大蒙特利尔多民族、低收入社区的24所市中心小学，对2108名9至12岁的学生（占符合条件学生的80.5%）进行了基线时身高、体重和肱三头肌皮褶厚度测量。通过课堂发放问卷收集学生的社会人口统计学和生活方式特征数据，家长在家自行填写问卷。
总体而言，35.2%的男孩和33.0%的女孩超重（根据美国国家健康与营养检查调查II（NHANES II）中针对年龄和性别的身体质量指数及肱三头肌皮褶厚度百分位数，超重定义为大于或等于第85百分位数）；15.1%的男孩和13.3%的女孩肥胖（根据美国国家健康与营养检查调查II（NHANES II）中针对年龄和性别的身体质量指数及肱三头肌皮褶厚度百分位数，肥胖定义为大于或等于第95百分位数）。年龄较小、一生都生活在加拿大、以及来自欧洲或中美洲/加勒比海家庭是男孩肥胖的独立相关因素。年龄较小、曾经吸烟、母亲肥胖和父亲肥胖是女孩肥胖的独立相关因素。亚洲家庭出身的女孩受到保护。
在这个低收入、多民族人群中超重学生的比例非常高，这表明迫切需要进行预防干预。
