One of the largest health disparities in the USA is in obesity rates between Black and White females.
The objective of this study was to test the hypothesis that the stress-obesity link is stronger in Black females than in White females aged 10-19.
Multilevel modeling captured the dynamic of acute (1 month) and chronic (10 years) stress and body mass index (BMI; weight in kilograms divided by height in meters squared) change in the National Heart, Lung, and Blood Institute Growth and Health Study, which consists of 2,379 Black and White girls across a span of socioeconomic status. The girls were assessed longitudinally from ages 10 to 19.
Higher levels of stress during the 10 years predicted significantly greater increases in BMI over time compared to lower levels of stress. This relationship was significantly stronger for Black compared to White girls.
Psychological stress is a modifiable risk factor that may moderate early racial disparities in BMI.
在美国,最大的健康差异之一是黑人和白人女性之间的肥胖率。
本研究的目的是检验这样一个假设,即在 10-19 岁的黑人女性中,压力与肥胖之间的联系比白人女性更强。
多水平模型捕捉了美国国家心肺血液研究所生长和健康研究中急性(1 个月)和慢性(10 年)压力和体重指数(BMI;体重以千克为单位除以身高以米为单位)变化的动态,该研究包括跨越社会经济地位的 2379 名黑人和白人女孩。这些女孩从 10 岁到 19 岁进行了纵向评估。
与低水平的压力相比,10 年内压力水平较高预示着 BMI 随时间显著增加。与白人女孩相比,这种关系在黑人女孩中更为显著。
心理压力是一个可改变的风险因素,可能会调节 BMI 方面早期的种族差异。
