To assess the association between perceived stress and adiposity among Chinese adults.
Cross-sectional study. Perceived stress was assessed using the 14-item perceived stress scale. Associations between quintiles of perceived stress and BMI and waist circumference were assessed using linear regression models and multinomial regression models. Estimates were adjusted for sociodemographic characteristics.
2015 China Health and Nutrition Survey: 12 provinces covering a variety of geographic, economic development and health indicator situations.
A total of 8385 adults of both sexes, aged 18-99 years, were included.
Overall, the mean perceived stress score was 22·7 (6·2), mean BMI was 24·3 (3·6) kg/m2 and prevalence of obesity (BMI ≥ 30 kg/m2) was 6·0 %. There were inverse associations between perceived stress quintiles with continuous BMI (P < 0·001), BMI categories (P = 0·015) and waist circumference (P = 0·047). Compared to adults in the lowest quintile of perceived stress, adults in the highest quintile of perceived stress had 0·44 kg/m2 lower mean BMI (95 % CI: -0·67, -0·21), 0·72 times the prevalence of obesity (95 % CI: 0·55, 0·94) and 0·73 times the prevalence of abdominal obesity (95 % CI: 0·61, 0·88). Results were similar when using Chinese-specific cut-points.
Our results showed inverse associations between perceived stress quintiles and adiposity among Chinese adults. Future studies should aim to better understand the directionality of the observed associations and the potential biological and behavioural mechanisms underlying these associations in the Chinese population.
评估中国成年人感知压力与肥胖之间的关系。
横断面研究。使用 14 项感知压力量表评估感知压力。使用线性回归模型和多项回归模型评估感知压力五分位数与 BMI 和腰围之间的关联。估计值调整了社会人口统计学特征。
2015 年中国健康与营养调查：涵盖各种地理、经济发展和健康指标情况的 12 个省份。
共纳入 8385 名 18-99 岁的男女成年人。
总体而言，感知压力的平均得分为 22.7（6.2），平均 BMI 为 24.3（3.6）kg/m2，肥胖（BMI≥30 kg/m2）的患病率为 6.0%。感知压力五分位数与连续 BMI（P<0.001）、BMI 类别（P=0.015）和腰围（P=0.047）呈负相关。与感知压力最低五分位数的成年人相比，感知压力最高五分位数的成年人平均 BMI 低 0.44 kg/m2（95%CI：-0.67，-0.21），肥胖的患病率高 0.72 倍（95%CI：0.55，0.94），腹型肥胖的患病率高 0.73 倍（95%CI：0.61，0.88）。使用中国特定切点的结果相似。
我们的结果表明，中国成年人感知压力五分位数与肥胖呈负相关。未来的研究应旨在更好地理解观察到的关联的方向性，以及中国人群中这些关联背后的潜在生物学和行为机制。
