PURPOSE
The objective of this analysis was to assess whether the association between sleep duration and BMI and between sleep duration and waist circumference is moderated by age and self-perceived stress.
METHODS
We analyzed data from 2034 participants enrolled in 2014 in the cross-sectional study Obesity in Romania Study-study of the prevalence of obesity and related risk factors in Romanian general population (ORO study).
RESULTS
Interaction between sleep duration, self-perceived stress and age, with BMI as dependent variable, was statistically significant after adjustment for demographic and lifestyle factors (p value for interaction 0.003). In participants without self-perceived stress, a linear negative association between sleep duration and BMI was observed only in those 18-39 years old (p = 0.049), with BMI decreasing in parallel with increased sleep duration. In participants with self-perceived stress, a U-shaped relationship was observed between BMI and sleep duration in those 40-64 years old, with higher BMI in those sleeping ≤ 6 h and ≥ 9 h/night compared to those sleeping > 6 and < 9 h/night (p = 0.002 and 0.005). Those ≥ 65 years old with self-perceived stress sleeping ≥ 9 h/night had a significantly higher BMI compared to those in other sleep duration categories (p = 0.041 vs. those sleeping ≤ 6 h/night and p = 0.013 vs. to those sleeping > 6 and < 9 h/night). No interaction between age, self-perceived stress and sleep duration, with waist circumference as dependent variable was observed.
CONCLUSIONS
In our sample, the association between sleep duration and BMI was moderated by self-perceived stress and age.
目的
本分析的目的是评估睡眠时间与体重指数（BMI）之间以及睡眠时间与腰围之间的关联是否受到年龄和自我感知压力的调节。
方法
我们分析了2014年参与罗马尼亚肥胖研究横断面研究的2034名参与者的数据，该研究旨在研究罗马尼亚普通人群中肥胖及相关危险因素的患病率（ORO研究）。
结果
以BMI为因变量，在调整人口统计学和生活方式因素后，睡眠时间、自我感知压力和年龄之间的交互作用具有统计学意义（交互作用的p值为0.003）。在没有自我感知压力的参与者中，仅在18 - 39岁的人群中观察到睡眠时间与BMI之间存在线性负相关（p = 0.049），BMI随着睡眠时间的增加而降低。在有自我感知压力的参与者中，40 - 64岁人群的BMI与睡眠时间之间呈U形关系，与每晚睡眠>6小时且<9小时的人群相比，睡眠≤6小时和≥9小时的人群BMI更高（p = 0.002和0.005）。自我感知压力且每晚睡眠≥9小时的65岁及以上人群的BMI显著高于其他睡眠时间类别的人群（与睡眠≤6小时/晚的人群相比p = 0.041，与睡眠>6小时且<9小时的人群相比p = 0.013）。未观察到以腰围为因变量时年龄、自我感知压力和睡眠时间之间的交互作用。
结论
在我们的样本中，睡眠时间与BMI之间的关联受到自我感知压力和年龄的调节。
