Abstract

Background: To examine longitudinal associations of early neighborhood Child Opportunity Index 2.0 (COI) with children's BMI trajectories and identify whether household economic resources moderate relations of COI in infancy/toddlerhood and the preschool years to longitudinal BMI growth between 2 and 12 years. Methods: Family data (n = 1091) were drawn from the Family Life Project, a longitudinal study of families residing in rural high-poverty areas. Neighborhood COI was obtained for each developmental period: infancy/toddlerhood (2-15 months) and the preschool years (2-5 years). BMIs were created from anthropometrics collected at six time points. Results: Higher neighborhood COIs during the infancy/toddlerhood (β = -0.0130, p < 0.01) and preschool years (β = -0.0093, p < 0.05) were associated with lower BMI at 5 years of age; although the latter became nonsignificant after adjusting for infancy/toddlerhood COI. Both household income and time spent in poverty moderated associations of infancy/toddlerhood exposure to neighborhood COI with BMI change. Among children residing in not poor households, higher neighborhood level child opportunity was associated with a slower increase in BMI from 2 to 12 years (β = -0.0369, p < 0.05), and a lower BMI at 12 years (β = -0.0395, p < 0.05). Conclusions: Neighborhood COI during the infant and toddler years is longitudinally associated with child growth, and long-term associations are evident among children residing in not poor households. Future work is needed to better understand how family and neighborhood-level resources interact to influence obesity risk, particularly for those at high risk.

家庭收入调节邻里儿童机会指数与BMI增长的纵向关系。
背景:研究早期邻里儿童机会指数2.0 (COI)与儿童BMI轨迹的纵向关联,并确定家庭经济资源是否调节婴幼儿期和学龄前儿童机会指数2.0与2 - 12岁儿童BMI纵向增长的关系。方法:家庭数据(n = 1091)来自家庭生活项目,这是一项对农村高贫困地区家庭的纵向研究。每个发育阶段的邻里COI:婴儿期/幼儿期(2-15个月)和学龄前(2-5岁)。bmi是根据在六个时间点收集的人体测量数据创建的。结果:婴幼儿期(β = -0.0130, p < 0.01)和学龄前(β = -0.0093, p < 0.05)较高的邻里COIs与5岁时较低的BMI相关;尽管后者在调整了婴儿期/幼儿期COI后变得不显著。家庭收入和贫困时间都调节了婴幼儿暴露于社区COI与BMI变化的关系。在非贫困家庭的儿童中,较高的邻里儿童机会与2至12岁时BMI增长缓慢相关(β = -0.0369, p < 0.05),与12岁时较低的BMI相关(β = -0.0395, p < 0.05)。结论:婴幼儿时期的邻里COI与儿童的成长有纵向关系,而在非贫困家庭的儿童中,这种长期关系也很明显。未来的工作需要更好地了解家庭和社区资源如何相互作用来影响肥胖风险,特别是对于那些高风险的人。

期刊介绍: Childhood Obesity is the only peer-reviewed journal that delivers actionable, real-world obesity prevention and weight management strategies for children and adolescents. Health disparities and cultural sensitivities are addressed, and plans and protocols are recommended to effect change at the family, school, and community level. The Journal also reports on the problem of access to effective healthcare and delivers evidence-based solutions to overcome these barriers.
