To describe the gender and regional differences in patterns of physical activity and sedentary behavior across 10 study areas through data from the China Kadoorie Biobank (CKB) that involving half a million adults.
The baseline survey of CKB took place in 5 urban and 5 rural areas across China during 2004-2008. After excluding those who had a prior history of heart disease, stroke and/or cancer, 486 514 participants (age: 30-79 y) were included in the analyses. MET-h/d was calculated for each one of the participant, based on the type, duration and intensity of self-reported physical activity, along with time spent on sedentary activity. These data were compared, after standardization for age between sex and study areas.
The mean total physical activity was 22.9 MET-h/d among men, 20.6 MET-h/d among women, and the mean sedentary leisure time appeared 3.1 h/d in men and 2.9 h/d in women. In men, the total physical activity ranged from 13.3 MET-h/d in Haikou to 31.3 MET-h/d in Zhejiang, while in women it ranged from 14.7 MET-h/d to 30.2 MET-h/d across the 10 areas. For sedentary leisure time, it ranged from 2.0 h/d in Zhejiang to 3.8 h/d in Sichuan in men and 1.6 h/d to 3.7 h/d in women. In both men and women, occupational physical activities (77.6% and 59.8% respectively) accounted for most of the daily activities, while leisure time physical activities accounted for the least (3.1% in both men and women). Among men, the proportion of occupational physical activity ranged from 86.5% in Zhejiang to 69.4% in Haikou (69.4%), while in women it ranged from 74.8% in Zhejiang to 40.9% in Henan. Gansu (men 17.8%, women 18.1%) reported the highest proportion of transportation physical activities. Among women, areas reporting the highest proportion of physical activity at home would include Henan (54.0%) and Hunan (39.1%), whereas adults in Zhejiang (20.0%) reported the lowest proportion. Among men, Hunan (18.0%) reported the highest proportion of physical activity at home. Compared with rural areas, male and female participants from urban areas tended to have more leisure time for physical activity and less vigorous-intensity physical activity.
The patterns of physical activity and sedentary behavior including the levels of physical activity, domains and intensity of physical activities. Sedentary leisure time appeared all various greatly across different regions in China.
通过来自中国嘉道理生物银行（CKB）涉及50万成年人的数据，描述10个研究地区身体活动和久坐行为模式的性别及地区差异。
CKB的基线调查于2004年至2008年在中国5个城市和5个农村地区进行。在排除有心脏病、中风和/或癌症既往史的人群后，486514名参与者（年龄：30 - 79岁）纳入分析。根据自我报告的身体活动类型、持续时间和强度以及久坐活动时间，为每位参与者计算代谢当量小时/天（MET - h/d）。在对性别和研究地区的年龄进行标准化后，对这些数据进行比较。
男性的平均总身体活动量为22.9 MET - h/d，女性为20.6 MET - h/d，男性的平均久坐休闲时间为3.1小时/天，女性为2.9小时/天。男性的总身体活动量在海口为13.3 MET - h/d至浙江的31.3 MET - h/d之间，而女性在10个地区的范围为14.7 MET - h/d至30.2 MET - h/d。对于久坐休闲时间，男性在浙江为2.0小时/天至四川的3.8小时/天，女性为1.6小时/天至3.7小时/天。男性和女性的职业身体活动（分别为77.6%和59.8%）占日常活动的大部分，而休闲时间身体活动占比最小（男性和女性均为3.1%）。男性中，职业身体活动的比例在浙江为86.5%至海口的69.4%，而女性在浙江为74.8%至河南的40.9%。甘肃（男性17.8%，女性18.1%）报告的交通身体活动比例最高。在女性中，报告在家中身体活动比例最高的地区包括河南（54.0%）和湖南（39.1%），而浙江的成年人（20.0%）报告的比例最低。在男性中，湖南（18.0%）报告的在家中身体活动比例最高。与农村地区相比，城市地区的男性和女性参与者往往有更多的休闲时间进行身体活动，但剧烈强度的身体活动较少。
身体活动和久坐行为模式包括身体活动水平、身体活动领域和强度。在中国不同地区，久坐休闲时间差异很大。
