American Indian (AI) children have a combined overweight and obesity prevalence of 53%. Behaviors that contribute to obesity, such as sugar sweetened beverage (SSB) intake and time spent in physical activity (PA), have been poorly explored in this population. The purpose of this study is to report body mass index (BMI), SSB intake, and time spent in PA of 7-to-13-year-old AI children who reside in rural and urban areas in Oklahoma. Cross-sectional survey study. Self-reported SSB intake in the last month, and time spent in PA were collected via questionnaires. Height and weight were professionally measured. The sample included 124 7-to-13-year-old AI children who attended a diabetes prevention summer camp in 2013. BMI percentile, overweight and obesity prevalence, SSB intake, time spent in PA, and number of participants meeting the Physical Activity Guidelines for Americans. Descriptive characteristics for BMI percentile, overweight and obesity, SSB intake, time spent in PA, and meeting PA recommendations were calculated using means, standard deviations, and frequencies. Independent t test and Chi square analyses were used to test for gender differences. Participants were 10.2 ± 1.5 years old and 57% female. Sixty-three percent were overweight or obese. Children consumed 309 ± 309 kcal/day of SSB and spent 4.4 ± 3.8 h per week in moderate-to-vigorous PA. Approximately 32% met the 2008 Physical Activity Guidelines for Americans. No gender differences were observed. The prevalence of overweight and obesity was higher than previously reported in a similar population, and higher than that of US children in the general population. SSB intake and physical activity levels were also found to be higher in this group than in the general population.
美国印第安（AI）儿童超重和肥胖的综合患病率为53%。导致肥胖的行为，如含糖饮料（SSB）摄入量和体育活动（PA）时间，在这一人群中尚未得到充分研究。本研究的目的是报告居住在俄克拉荷马州农村和城市地区的7至13岁AI儿童的体重指数（BMI）、SSB摄入量和PA时间。横断面调查研究。通过问卷调查收集过去一个月自我报告的SSB摄入量和PA时间。身高和体重由专业人员测量。样本包括2013年参加糖尿病预防夏令营的124名7至13岁AI儿童。BMI百分位数、超重和肥胖患病率、SSB摄入量、PA时间以及符合《美国人体育活动指南》的参与者人数。使用均值、标准差和频率计算BMI百分位数、超重和肥胖、SSB摄入量、PA时间以及符合PA建议的描述性特征。使用独立t检验和卡方分析来检验性别差异。参与者的年龄为10.2±1.5岁，女性占57%。63%的人超重或肥胖。儿童每天摄入309±309千卡的SSB，每周进行4.4±3.8小时的中度至剧烈PA。约32%的人符合2008年《美国人体育活动指南》。未观察到性别差异。超重和肥胖的患病率高于之前在类似人群中的报告，也高于美国普通人群中的儿童。该组的SSB摄入量和身体活动水平也高于普通人群。
