摘要
目的 探索上海市嘉定区20～74岁社区居民静坐时间与全因死亡风险的关系,为静坐行为指导提供科学依据.方法 基于上海市高峰人群队列在嘉定区的项目点数据,排除静坐时间缺失的个体后,最终纳入10 038人.个体的静坐时间通过基线调查问卷获得,个体的死亡信息通过链接死亡监测系统和主动的定向监测获取.采用Cox比例风险回归模型评估死亡风险.结果 2017年7月1日-2022年12月31日,研究对象平均随访(5.4±0.4)年(共观察53 985.7人年),随访期间发生205例死亡事件.静坐时间0～＜4 h/d、4～＜6 h/d、6～＜8 h/d、≥8 h/d组的死亡率分别为1.8％(89/5 040)、2.0％(54/2 654)、2.8％(26/945)、2.6％(36/1 399).Kaplan-Meier 生存曲线显示,4组的全因死亡风险随着随访时间增加而上升,组间差异无统计学意义(Log-Rank x2=6.230,P=0.101).Cox比例风险回归模型显示,调整混杂后,与静坐时间0～＜4 h/d组相比,6～＜8 h/d、≥8h/d组的全因死亡发生风险均增加(HR6～＜8h/d组=1.602,95％CI:1.007～2.548,P=0.047;HR≥8h/d组=1.670,95％CI:1.100～2.538,P=0.016).结论 静坐时间是全因死亡发生风险的独立危险因素,每天静坐时间≥6 h后死亡风险增加.未来仍需针对不同人群采取个性化的干预措施,避免长时间静坐.
Abstract
Objective To explore the relationship between sedentary time and mortality of the community residents aged 20-74 in Jiading District,Shanghai,in order to provide a scientific basis for the guidance of sedentary behavior.Methods Based on the project site data of Shanghai Peak Cohort in Jiading District,a total of 10 038 individuals without missing sedentary time were used as baseline data.Sedentary time was obtained through baseline questionnaires,and individual death information was obtained from the death surveillance system and active surveillance.The Cox proportional risk model was used to assess the risk of death.Results As of December 31,2022,the mean follow-up was(5.4±0.4)years(53 985.7 person-years).During the follow-up period,205 deaths occurred.The mortality rates in the groups 0-＜4 h/d,4-＜6 h/d,6-＜8 h/d and ≥ 8 h/d were 1.8％(89/5 040),2.0％(54/2 654),2.8％(26/945)and 2.6％(36/1 399),respectively.Kaplan-Meier curve showed that the risk of all-cause death increased with the increase of follow-up time in the four groups,but there was no statistically significant difference between groups(Log-Rank x2=6.230,P=0.101).Compared to the community residents with sedentary time 0-＜4 h/d,those with sedentary time 6-＜8 h/d and ≥ 8 h/d had an increased risk of all-cause death(HR6_＜8h/d group=1.602,95％CI:1.007-2.548,P=0.047;HR≥8h/d group=1.670,95％CI:1.100-2.538,P=0.016).Conclusions Sedentary time is an independent risk factor for all-cause mortality in the community residents,and those with sedentary time ≥6 h/d have an increased risk of all-cause death.In the future,we need to take personalized intervention to avoid high levels of sedentary behavior.
