Physical activity (PA) and sedentary behavior (SB) include several domains, whether the association of PA and SB with perceived stress is domain-specific is not clear. This study aims to identify associations of physical activity (exercise and housework) and leisure-time sedentary behavior (LTSB) with perceived stress among Chinese adults.
The data were collected from the 2015 China Health and Nutrition Survey (CHNS). Respondents completed multiple questionnaires developed by the CHNS team, from which we extracted and sorted PA and LTSB data. Perceived stress was measured using the 14-item Perceived Stress Scale. PA was measured using a questionnaire covering 7 types of commonly practiced exercises and 4 types of housework activities among Chinese individuals. Consecutive questions were used to inquire about the time spent on each type of PA. The measurement of LTSB was conducted in the same manner. Data analysis involved Chi-square test and logistic regression.
11,471 adults were included, with an average age of 52.3 years, and 48.3 % were male. 69.9 % (8,019) of respondents reported high perceived stress. Following adjustment for age, gender and other factors, perceived stress was lower for adults reporting medium exercise time (1-2 h) compared with excessively (≥2 h) (OR=1.314 [95 %CI 1.071, 1.612], P<0.001) and least (<1 h) (OR=1.273 [95 %CI 1.115, 1.413], P<0.001) active adults. Perceived stress was higher for adults reporting less housework time (<1 h) compared with adults spending medium (1-2 h) (OR=0.860 [0.744, 0.993], P<0.05) and long (≥2 h) (OR=0.725 [95 %CI 0.628, 0.838], P<0.001) time on housework. Low-level LTSB (<2 h) was associated with higher perceived stress than medium- (2-4 h) (OR=0.817 [0.718, 0.930], P<0.01) and high-level LTSB (≥4 h) (OR=0.668 [0.577, 0.773], P<0.001).
The association of PA and SB with perceived stress is domain-specific. Medium exercise time and extended housework time are associated with reduced perceived stress. Additionally, our findings suggesting that increasing the time spent on LTSB is linked to lower perceived stress levels.
身体活动（PA）和久坐行为（SB）包含多个领域，PA和SB与感知压力之间的关联是否具有领域特异性尚不清楚。本研究旨在确定中国成年人的身体活动（锻炼和家务）及休闲时间久坐行为（LTSB）与感知压力之间的关联。
数据来自2015年中国健康与营养调查（CHNS）。受访者完成了由CHNS团队编制的多份问卷，我们从中提取并整理了PA和LTSB数据。使用14项感知压力量表测量感知压力。通过一份涵盖7种常见锻炼类型和4种家务活动类型的问卷对中国人群的PA进行测量。使用连续问题询问每种PA类型所花费的时间。LTSB的测量方式相同。数据分析采用卡方检验和逻辑回归。
共纳入11471名成年人，平均年龄52.3岁，男性占48.3%。69.9%（8019人）的受访者报告感知压力较高。在对年龄、性别和其他因素进行调整后，报告中等锻炼时间（1 - 2小时）的成年人的感知压力低于锻炼过度（≥2小时）（OR = 1.314 [95%CI 1.071, 1.612]，P < 0.001）和锻炼最少（<1小时）（OR = 1.273 [95%CI 1.115, 1.413]，P < 0.001）的活跃成年人。与花费中等（1 - 2小时）（OR = 0.860 [0.744, 0.993]，P < 0.05）和较长（≥2小时）（OR = 0.725 [95%CI 0.628, 0.838]，P < 0.001）时间做家务的成年人相比，报告做家务时间较少（<1小时）的成年人感知压力更高。低水平LTSB（<2小时）与较高的感知压力相关，高于中等水平（2 - 4小时）（OR = 0.817 [0.718, 0.930]，P < 0.01）和高水平LTSB（≥4小时）（OR = 0.668 [0.577, 0.773]，P < 0.001）。
PA和SB与感知压力之间的关联具有领域特异性。中等锻炼时间和较长的家务时间与较低的感知压力相关。此外，我们的研究结果表明，增加LTSB的时间与较低的感知压力水平相关。
