江苏省心血管病高危人群身体活动与休闲静坐时间状况

  目的  了解江苏省心血管病高危人群身体活动与休闲静坐时间现状，为制定改善居民身体活动策略提供基础资料和科学依据。  方法  将2015年9月1日―2017年6月30日江苏省6个项目点16 066名35~75岁心血管病高危人群纳入本研究。采用问卷收集个人基础信息、身体活动资料，分析不同特征身体活动与休闲静坐时间状况。  结果  身体活动强度值用代谢当量(metabolic equivalent, MET)表示，研究对象每天总身体活动水平的中位数为11.94 MET-h/d，工作和家务相关身体活动所占比例为87.90%，且不同特征人群身体活动模式各异。每天休闲静坐时间的中位数为1.71 h/d，49.00%的个体每天休闲静坐时间超过2.00 h/d，男性每天休闲静坐时间超过2.00 h/d的比例高于女性(χ2 =122.30, P＜0.001)。  结论  江苏省心血管病高危人群身体活动以工作和家务为主，每天休闲静坐时间超过2.00 h/d者比例较高，应根据不同人群的具体情况进行针对性的健康教育工作。

  Objective  To investigate the status of physical activity and leisure sit-in time among the high-risk population of cardiovascular disease (CVD) in Jiangsu Province, and provide basis data for the formulation of strategies to improve the physical activity of residents.  Methods  From September 1, 2015 to June 30, 2017, 16 066 high-risk groups of CVD aged 35-75 years from 6 project sites in Jiangsu Province were included in this study. Specifically designed questionnaires were used to collect basic personal information and physical activity data, and the physical activity and leisure sit-in time status with different characteristics was analyzed.  Results  The value of physical activity intensity is expressed in metabolic equivalent (MET), the median total physical activity was 11.94 MET-h/d, the proportion of physical activities related to work and housework was 87.90%, and the physical activity patterns of people with different characteristics were different. The median daily leisure sit-in time was 1.71 h/d, 49.00% of individuals spend more than 2.00 h/d in leisure sit-in every day, the proportion of men who spend more than 2.00 h/d of leisure sit-in per day was higher than that of women (χ2 =122.30, P < 0.001).  Conclusion  The physical activities of the high-risk population of CVD in Jiangsu Province are mainly work and housework, and the proportion of CVD who spend more than 2.00 h/d in leisure sit-in is high, targeted health education should be carried out according to the specific conditions of different groups.
