评估家庭环境因素与美国印第安儿童BMI之间的关系。横断面和前瞻性研究。在南达科他州的一个北方平原印第安人保留地进行的以学校为基础的肥胖预防试验（光明的开始）。混合模型多变量分析用于检查儿童BMI类别（正常，超重和肥胖）与家庭食物供应，儿童饮食摄入量和体力活动之间的关联。分析调整了年龄，性别，社会经济地位，父母BMI和学校;前瞻性分析也调整了研究条件和基线预测和结果变量。测量幼儿园儿童（n 424，51%男性;平均年龄= 5.8岁，30%超重/肥胖）和父母/照顾者（89%女性; 86%超重/肥胖）的身高和体重，父母/照顾者完成家庭环境因素调查（基线和2年后）。较高的快餐摄入量和父母认为的身体活动障碍与儿童超重和肥胖的可能性较高略有相关。蔬菜供应与超重和肥胖的可能性较低略有相关。家庭环境因素与随访时儿童体重状况之间的相关性不显著。研究结果表明，选定的方面的家庭环境与美国印第安儿童的体重状况。针对这一人群的肥胖干预措施应考虑帮助父母参与和塑造健康行为，并增加家中健康食品的供应。
To evaluate associations between home environmental factors and BMI of young American-Indian children. Cross-sectional and prospective study. School-based obesity prevention trial (Bright Start) on a Northern Plains Indian reservation in South Dakota. Mixed model multivariable analysis was used to examine associations between child BMI categories (normal, overweight and obese) and home food availability, children’s dietary intake and physical activity. Analyses were adjusted for age, gender, socio-economic status, parent BMI and school; prospective analyses also adjusted for study condition and baseline predictor and outcome variables. Kindergarten children (n 424, 51% male; mean age = 5·8 years, 30% overweight/obese) and parents/caregivers (89% female; 86% overweight/obese) had their height and weight measured and parents/caregivers completed surveys on home environmental factors (baseline and 2 years later). Higher fast-food intake and parent-perceived barriers to physical activity were marginally associated with higher probabilities of a child being overweight and obese. Vegetable availability was marginally associated with lower probabilities of being overweight and obese. The associations between home environmental factors and child weight status at follow-up were not significant. Findings indicate that selected aspects of the home environment are associated with weight status of American-Indian children. Obesity interventions with this population should consider helping parents to engage and model healthful behaviours and to increase availability of healthful foods at home.
