分析中国成年人休闲时间的久坐行为及相关社会人口学因素。
采用2012年中国营养与健康调查的体力活动问卷收集数据，共调查了142369名18岁及以上的受试者（男性62563名，女性79806名）的休闲时间久坐行为。
久坐活动总时长平均为2.66小时/天。约82.1%的18岁及以上居民休闲时间久坐活动时长在2小时及以上。城市居民（83.0%）、男性（83.8%）、受教育程度较高者、家庭收入较高者（83.6%）以及未婚者（89.1%）的这一比例高于相应对照人群，随着年龄降低和受教育程度提高，久坐活动时长在2小时及以上的比例增加。Logistic回归模型显示，不同社会决定因素导致的比例有所不同。
中国居民在久坐活动上花费时间较多，且这种模式因社会人口学因素而异。
