身体活动（PA）和久坐行为（SB）具有季节性模式。目前尚不清楚这些模式与睡眠、气象因素和健康之间的关系。方法：在2011年7月至2016年5月期间，在中年人中，（50-64岁）、中老年人（65-74岁）和老年-老年人（>= 75岁）参与者（n = 1116）。气象因素（环境温度、风速、日照时数、降水和最低能见度）在当地记录。我们首先研究了PA，SB和夜间睡眠的季节性，按年龄组分层。其次，我们考察了气象因素的影响。第三，我们模拟了潜在的季节性的所有原因的死亡风险，由于PA和SB的季节性，通过使用以前公布的相对risk.Results：水平的光和中度到有力的PA是在夏季比冬季中年（季节变化= 18.1和14.8分钟/天）和老年人（12.8和8.6分钟/天）。环境温度和日照时数解释了这种模式。中年人冬季夜间睡眠时间延长31.8分钟/天。SB没有表现出季节性模式。老年人的活动水平没有观察到季节性。全因死亡的风险可能会更高，在冬季比在夏季由于低水平的中度到剧烈PA和高水平的SB的积累。结论：PA有较大程度的季节性比SB和夜间睡眠中老年人和年轻人。SB似乎在日常生活中根深蒂固。建议用轻PA中断SB可能是公共卫生机构的一个很好的起点。
Introduction: Physical activity (PA) and sedentary behavior (SB) have seasonal patterns. It remains unclear how these patterns are associated with sleep, meteorological factors, and health.Methods: Activity levels were continuously measured with an accelerometer for seven days between July 2011 and May 2016, among middle-aged (50-64 years), young-elderly (65-74 years) and old-elderly (>= 75 years) participants of a population-based Dutch cohort study (n = 1116). Meteorological factors (ambient temperature, wind speed, sunlight hours, precipitation, and minimum visibility) were locally recorded. We first examined the seasonality of PA, SB, and nighttime sleep, stratified by age group. Second, we examined the influence of meteorological factors. Third, we modeled the potential seasonality of the all-cause mortality risk due to the seasonality of PA and SB, by using previously published relative risks.Results: Levels of light and moderate-to-vigorous PA were higher in summer than in winter among middle-aged (seasonal variation = 18.1 and 14.8 min/day) and young-elderly adults (12.8 and 8.6 min/day). The pattern was explained by ambient temperature and sunlight hours. Nighttime sleep was 31.8 min/day longer in winter among middle-aged adults. SB did not show a seasonal pattern. No seasonality in activity levels was observed among old-elderly adults. The all-cause mortality risk may be higher in winter than in summer due to the accumulation of low levels of moderate to vigorous PA and high levels of SB.Conclusion: PA has a larger degree of seasonality than SB and nighttime sleep among middle-aged and young elderly adults. SB appears strongly ingrained in daily routine. Recommending the interruption of SB with light PA might be a good starting point for public health institutions.
