This study investigates the association between sedentary behavior and sleep quality among postmenopausal women residing in China's plateau regions. Particular attention is given to moderating effects of age, body mass index (BMI), and sleep environment. This study aims to identify modifiable risk factors influencing sleep quality in this high-altitude population.
This cross-sectional study focused on postmenopausal women (aged ≥50 years, ≥12 months post-menopause) across four primary plateau regions in China: Qinghai-Tibet, Yunnan-Guizhou, Inner Mongolia, and the Loess Plateau. Sedentary behavior was evaluated with the Older Adults Sedentary Behavior Questionnaire, and sleep quality was assessed with the Pittsburgh Sleep Quality Index. Data analysis encompassed descriptive statistics, correlation analysis, multiple linear regression, and subgroup analyses.
Among the 151 participants (mean age 58.5 years), sedentary behavior was positively correlated with poorer sleep quality ( = 0.36, < 0.001). Improvements in the sleep environment were similarly associated with better sleep quality ( = 0.29, < 0.001). Multiple linear regression identified sedentary behavior and sleep environment as significant predictors of sleep quality, while other variables showed no significant associations. Subgroup analysis revealed age-specific effects: sedentary behavior had a strong influence on sleep quality in women under 60 years ( = 0.36, < 0.01) but demonstrated a weaker, non-significant association in those aged 60 years or older ( = 0.062).
Prolonged sedentary behavior is an independent risk factor for reduced sleep quality among postmenopausal women residing in high-altitude regions, while improvements in the sleep environment are positively associated with better sleep quality. The influence of sedentary behavior on sleep quality varies by age groups. These findings highlight the importance of tailored interventions and health policies to improving sleep quality in postmenopausal women living at high altitudes.
本研究调查中国高原地区绝经后女性久坐行为与睡眠质量之间的关联。特别关注年龄、体重指数（BMI）和睡眠环境的调节作用。本研究旨在确定影响该高海拔人群睡眠质量的可改变风险因素。
这项横断面研究聚焦于中国四个主要高原地区（青藏高原、云贵高原、内蒙古高原和黄土高原）的绝经后女性（年龄≥50岁，绝经≥12个月）。采用老年人久坐行为问卷评估久坐行为，并用匹兹堡睡眠质量指数评估睡眠质量。数据分析包括描述性统计、相关性分析、多元线性回归和亚组分析。
在151名参与者（平均年龄58.5岁）中，久坐行为与较差的睡眠质量呈正相关（r = 0.36，P < 0.001）。睡眠环境的改善同样与较好的睡眠质量相关（r = 0.29，P < 0.001）。多元线性回归确定久坐行为和睡眠环境是睡眠质量的重要预测因素，而其他变量未显示出显著关联。亚组分析揭示了年龄特异性影响：久坐行为对60岁以下女性的睡眠质量有强烈影响（r = 0.36，P < 0.01），但在60岁及以上女性中显示出较弱的、不显著的关联（r = 0.062）。
久坐行为延长是高海拔地区绝经后女性睡眠质量下降的独立危险因素，而睡眠环境的改善与较好的睡眠质量呈正相关。久坐行为对睡眠质量的影响因年龄组而异。这些发现凸显了针对性干预措施和健康政策对改善高海拔地区绝经后女性睡眠质量的重要性。
