确定肥胖(BMI z评分)的纵向个人、社会和环境预测因素，以及对健康体重儿童和青少年不健康体重增加的恢复力。在基线和三年后，对200名健康体重的5-12岁儿童及其父母进行了调查，他们生活在社会经济不利的社区。客观测量儿童的身高和体重，父母完成详细的问卷调查，检查家庭、社会和邻里环境，并使用地理信息系统数据评估客观的邻里环境测量。被归类为健康体重的儿童，如果他们的BMI z得分在基线和三年随访期间有轻微或中等的增长(位于底部和中间)，则被归类为对不健康体重增加的恢复能力。在适用的情况下，使用完全调整的多变量回归模型来确定基线个人内、社会和环境预测因素，以确定儿童在随访时的BMI z得分，以及在随访时对不健康体重增加的恢复力。母亲预防孩子久坐行为的效果(B = −0.03，95%CI：−0.06，0.00)与随访时较低的儿童体重指数z得分有关。限制久坐行为的规则(OR = 1.14，95%CI：1.03，1.25)是对不健康体重增加有弹性的预测因素。研究结果表明，支持父母限制孩子久坐行为的策略，对于防止社会经济弱势群体中不健康的体重增加可能很重要。
To identify longitudinal individual, social and environmental predictors of adiposity (BMI z-score), and of resilience to unhealthy weight gain, in healthy weight children and adolescents. Two hundred healthy weight children aged 5–12 years at baseline and their parents living in socio-economically disadvantaged neighborhoods were surveyed at baseline and three years later. Children’s height and weight were objectively measured, parents completed a detailed questionnaire that examined the home, social and neighborhood environments, and objective measures of the neighborhood environment were assessed using geographic information system data. Children classified as healthy weight at baseline who had small or medium increases in their BMI z-score between baseline and three year follow up (those in the bottom and middle tertiles) were categorized as ‘resilient to unhealthy weight gain’. Where applicable, fully adjusted multivariable regression models were employed to determine baseline intrapersonal, social and environmental predictors of child BMI z-scores at follow-up, and resilience to unhealthy weight gain at follow-up. Maternal efficacy for preventing their child from engaging in sedentary behaviors (B = −0.03, 95 % CI: −0.06, 0.00) was associated with lower child BMI z-score at follow up. Rules to limit sedentary behaviors (OR = 1.14, 95 % CI: 1.03, 1.25) was a predictor of being resilient to unhealthy weight gain. The findings suggest that strategies to support parents to limit their children’s sedentary behavior may be important in preventing unhealthy weight gain in socioeconomically disadvantaged communities.
