我们分析了成年早期体重的影响,以及随着年龄的增长到成年中期体重随时间的变化对自测健康(SRH)的影响。虽然先前的研究集中在老年人的横断面样本上,但我们使用来自NHANES I流行病学跟踪研究(NHEFS)的纵向数据和双轨迹潜在增长模型来研究身体质量指数(BMI)和20年来SRH轨迹之间的关联。结果表明,成年早期的高BMI和随着时间的推移体重增加都与健康评级下降得更快有关。仅在白人女性中,那些体重指数在基线水平较高的女性报告的初始SRH也较低。体重与健康的关系中有一小部分是由于社会人口因素,而不是基线健康行为或医疗条件。这些发现为累积劣势观点提供了新的支持,记录了一群年轻人中日益加剧的健康不平等。
We analyze the influence of body weight in early adulthood, and changes in weight over time, on self rated health (SRH) as people age into mid-adulthood. While prior research focused on cross-sectional samples of older adults, we use longitudinal data from the NHANES I Epidemiologic Follow-up Study (NHEFS) and double-trajectory latent growth models to study the association between body mass index (BMI) and SRH trajectories over twenty years. Results indicate that high BMI in early adulthood and gaining more weight over time are both associated with a faster decline in health ratings. Among white women only, those with a higher BMI at the baseline also report lower initial SRH. A small part of the weight-health associations is due to sociodemographic factors, but not baseline health behaviors or medical conditions. The findings provide new support for the cumulative disadvantage perspective, documenting the increasing health inequalities in a cohort of young adults.
