肥胖是美国印第安人（AI）儿童的一个严重且日益严重的健康问题。我们的研究，威斯康星州营养和生长研究（WINGS），是一个正在进行的社区为基础的参与性研究伙伴关系之间的大学为基础的健康调查和3威斯康星州美国印第安部落的一部分。WINGS旨在了解WI部落儿童肥胖的患病率和影响因素，并为干预设计提供基础。本文重点研究了WINGS研究中3-8岁AI儿童的年龄、性别和3种体重状况指标与代理人报告的体力活动和电视/屏幕时间之间的关联。在一项横断面设计中，581名AI儿童（49.1%为女性，年龄3-8岁）参加了健康筛查。筛查包括身高、体重、腰围、体脂百分比，以及关于人口统计学和健康的家长调查，包括关于体育活动和电视/屏幕时间的问题。45%的儿童超重或肥胖。男孩明显比女孩更肥胖，体脂含量也更高。在检查的儿童的年龄范围内，体重类别没有差异。男孩每周参加的体育活动明显多于女孩，年龄较小的儿童参加体育活动的比例高于年龄较大的儿童。BMI和腰围与电视/屏幕时间或3项活动指标（体育参与，户外活动时间或学校体育活动）无显著相关性。在控制母亲BMI和儿童年龄和性别的情况下，户外玩耍时间显著预测儿童体脂百分比。WI的年轻AI儿童在很小的时候就有很高的超重/肥胖率，户外玩耍可能在调节体脂方面发挥重要作用。有必要在早期制定肥胖预防干预措施。
Obesity is a serious and growing health problem in American Indian (AI) children. Our study, the Wisconsin Nutrition and Growth Study (WINGS), is part of an ongoing community based participatory research partnership between university-based health investigators and 3 Wisconsin American Indian tribes. WINGS aimed to understand the prevalence and contributing factors to pediatric obesity in WI tribes and provide the foundation for intervention design. This paper focuses on the associations among age, gender and 3 measures of weight status with proxy-reported physical activity and TV/screen time in 3–8 year old AI children in the WINGS study. In a cross-sectional design, 581 AI children (49.1% female, ages 3–8 yrs) participated in health screenings. Screenings included height, weight, waist circumference, percent body fat, and a parent survey on demographics and health, including questions on physical activity and TV/screen time. 45% of children were overweight or obese. Boys were significantly more obese and had higher levels of body fat than girls. There were no differences in weight category across the age range of children examined. Boys participated in significantly more weekly sports than girls and sports participation was higher in younger vs. older children. BMI and waist circumference were not significantly correlated with TV/screen time or with the 3 activity measures (sports participation, outdoor play time or school based physical activity). Hours of outdoor play significantly predicted child body fat percent controlling for maternal BMI and child age and gender. Young AI children in WI have high rates of overweight/obesity starting at a very early age, and outdoor play may play a significant role in mediating body fat. There is a need to develop obesity prevention interventions at early ages.
