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.
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.
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).
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.
男性和女性在加速度计测量的久坐行为和不同身体活动（PA）强度方面存在差异，但描述不足。作者检查了性别在时间使用活动组成和总 PA 量方面的差异。
2013 年至 2015 年，对居住在城市和地区城市的 6000 名中年（40-64 岁）社区居民进行了一项横断面邮寄调查，采用随机抽样。参与者在腰部佩戴 Active style Pro HJA-350IT 连续 7 天。使用成分数据分析来检查活动时间使用方面的性别差异，以控制所有活动测量的时间分配。
共有 757 名参与者（303 名男性，52.3 [7.1] 岁）具有有效数据，包括在分析中。女性平均每天久坐行为时间减少 12.6%，轻强度 PA 时间增加 23.4%，而中高强度 PA 时间无显著差异。女性的 PA 量明显大于男性（17.8 比 15.0 代谢当量小时/天）。
日本中年女性的 PA 水平高于男性，因为她们花费更多的时间进行轻强度 PA。鉴于轻强度 PA 的健康益处，仅评估中高强度 PA 可能会导致低估女性的 PA 参与度。
