Background: Findings on the relationships between household food insufficiency (HFI), maternal stress, and youth body mass index (BMI) are mixed, possibly due to cross-sectional study designs and measurement issues. Furthermore, little is known about how childhood exposure to HFI and maternal stress influences BMI into young adulthood among rural youth. We aimed to determine the independent and moderating relationships of HFI and maternal perceived stress on youth BMI trajectories from age 9 to 24 years.

母亲压力调节美国农村青年从儿童到成年早期食物不足与体重指数轨迹的关系

背景：关于家庭食物不足 (HFI)、母亲压力和青少年体重指数 (BMI) 之间关系的研究结果好坏参半，这可能是由于横断面研究设计和测量问题。此外，关于儿童时期暴露于 HFI 和母亲压力如何影响农村青年成年后的 BMI 知之甚少。我们旨在确定 HFI 和母亲感知压力对 9 至 24 岁青年 BMI 轨迹的独立和调节关系。
