California's rural agricultural communities face an increased burden of obesity and metabolic disease. The present objective is to define the social and environmental influences to child obesity and physical activity within Mexican-origin communities in California's Central Valley. A range of data (anthropometric, socioeconomic, demographic, cultural and environmental) were collected on more than 650 children enrolled in Niños Sanos, Familia Sana. Physical activity data were gathered from a subsample of children 4-7 years of age (n = 148) via accelerometer. Cross sectional analyses explored the relationship between BMI and physical activity and the influence of numerous social and environmental variables. In this sample 45 % of children were determined to be overweight or obese. Boys had a higher daily average moderate-to-vigorous physical activity than girls (p = 0.008). Chi square analyses showed weight status was associated with activity level in girls (p = 0.03) but not boys. Multivariate regression revealed several social and environmental indicators influenced BMI and physical activity (p = 0.004). In this population of school-age children of Mexican-origin, girls may benefit more from targeted efforts to increase MVPA. Family and community support systems may also boost child participation in physical activities.
加利福尼亚州的农村农业社区面临着日益加重的肥胖和代谢疾病负担。当前的目标是确定加利福尼亚州中央谷地墨西哥裔社区中影响儿童肥胖和身体活动的社会及环境因素。我们收集了650多名参加“健康儿童，健康家庭”项目的儿童的一系列数据（人体测量、社会经济、人口统计、文化和环境数据）。通过加速度计从4至7岁儿童的一个子样本（n = 148）中收集身体活动数据。横断面分析探讨了体重指数（BMI）与身体活动之间的关系以及众多社会和环境变量的影响。在这个样本中，45%的儿童被判定为超重或肥胖。男孩的每日平均中等到剧烈身体活动水平高于女孩（p = 0.008）。卡方分析表明，体重状况与女孩的活动水平相关（p = 0.03），但与男孩无关。多变量回归显示，若干社会和环境指标影响了BMI和身体活动（p = 0.004）。在这个墨西哥裔学龄儿童群体中，有针对性地努力增加中等至剧烈身体活动（MVPA）可能会让女孩受益更多。家庭和社区支持系统也可能会促进儿童参与体育活动。
