Prior studies examining the association between perceived stress and adiposity have reported mixed findings, and sex differences have largely not been examined.
We examined the relationship between perceived stress and body mass index (BMI) and waist circumference in young adults in the National Longitudinal Study of Adolescent to Adult Health. Participants (mean age 29 years; N = 14,044) completed the short form of Cohen's Perceived Stress Scale during a home visit. Height, weight, and waist circumference were assessed during the same visit. BMI was calculated based on measured height and weight.
In the sample, 52% were male and 65% were identified as white. In adjusted linear regression analyses, a sex by Perceived Stress Scale interaction was noted (P < .05) for both BMI and waist circumference. Perceived stress was statistically significantly associated with lower BMI (β: -0.09; standard error [SE]: 0.05) and was associated with lower waist circumference, although not statistically significant (β: -0.18; SE: 0.10) among men. No associations were noted among women.
In this nationally representative sample of young adults, perceived stress was associated with lower levels of adiposity among men. Noted differences could be attributed to different behavioral and coping strategies in response to stress between men and women as well as biological mechanisms which should be explored further.
先前关于感知压力与肥胖之间关联的研究结果不一，且在很大程度上未对性别差异进行考察。
在“青少年到成人健康全国纵向研究”中，我们考察了年轻成年人的感知压力与体重指数（BMI）及腰围之间的关系。参与者（平均年龄29岁；N = 14,044）在一次家访中完成了科恩感知压力量表简版。在同一次家访中评估身高、体重和腰围。根据测量的身高和体重计算BMI。
在样本中，52%为男性，65%被认定为白人。在调整后的线性回归分析中，BMI和腰围在感知压力量表得分与性别的交互作用方面均有显著差异（P <.05）。感知压力与较低的BMI在统计学上显著相关（β：-0.09；标准误[SE]：0.05），且与男性较低的腰围相关，尽管未达到统计学显著水平（β：-0.18；SE：0.10）。在女性中未发现关联。
在这个具有全国代表性的年轻成年人样本中，感知压力与男性较低的肥胖水平相关。观察到的差异可能归因于男性和女性应对压力时不同的行为和应对策略以及生物学机制，对此应进一步探索。
