背景资料：加速度计测量的久坐行为和不同的身体活动（PA）强度之间的差异，男性和女性的描述很少。作者研究了时间使用活动组成和PA总量的性别差异。方法：2013年至2015年进行了一项横断面邮件调查，随机抽取了6000名中年人（40岁）。64岁）居住在城市和地区城市的社区居住日本成年人。受试者连续7天在腰部佩戴Active style Pro HJA-350 IT。使用成分数据分析来检查活动时间使用的性别差异，以控制所有活动测量所花费的时间。结果：共有757名参与者（303名男性，52.3 [7.1]岁）的有效数据被纳入分析。女性在久坐行为上花费的时间平均比男性少12.6%，在轻度PA上花费的时间平均比男性多23.4%，而在中度到剧烈PA上没有显著差异。妇女积累了显着更大的体积PA比男性（17.8比15.0代谢当量的任务h/d）。结论：日本中年女性的PA水平高于男性，因为她们在光强度PA中花费的时间更长。考虑到光强度PA的健康益处，仅评估中度至剧烈PA可能会导致低估女性？？？参与PA。
Background: Differences in accelerometer-measured sedentary behavior and different physical activity (PA) intensities between men and women have been poorly described. The authors examined gender differences in time-use activity composition and total volume of PA. Methods: A cross-sectional mail survey was conducted from 2013 to 2015 with a randomized sample of 6000 middle-aged (40???64 y) community-dwelling Japanese adults living in urban and regional cities. Participants wore Active style Pro HJA-350IT on their waist for 7 consecutive days. Gender differences in activity time use was examined using compositional data analysis to control for time spent in all activity measures. Results: In total, 757 participants (303 men, 52.3 [7.1] y) with valid data were included in the analysis. Women spent on average 12.6% less time in sedentary behavior and 23.4% more time in light-intensity PA than men, whereas no significant difference was found for moderate to vigorous PA. Women accumulated a significantly greater volume of PA than men (17.8 vs 15.0 metabolic equivalent of task h/d). Conclusions: Japanese middle-aged women showed higher levels of PA than men because they spent more time in light-intensity PA. Given the health benefits of light-intensity PA, evaluating only moderate to vigorous PA may lead to an underestimation of women???s participation in PA.
