The aim was to investigate associations between leisure-time physical activity (LTPA) and mortality, and associations between desire to increase LTPA and mortality within the low LTPA group. A public health survey questionnaire was sent in 2008 to a stratified random sample of the population aged 18-80 in southernmost Sweden, yielding a 54.1% response rate. Baseline 2008 survey data with 25,464 respondents was linked to cause of death register data to create a prospective cohort with 8.3-year follow-up. Associations between LTPA, desire to increase LTPA and mortality were analyzed in logistic regression models. An 18.4% proportion performed regular exercise (at least 90 min/week, leading to sweating), 23.2% moderate regular exercise (once or twice a week at least 30 min/occasion, leading to sweating), 44.3% moderate exercise (more than two hours walking or equivalent activity/week) and 14.1% reported low LTPA (less than two hours walking or equivalent activity/week). These four LTPA groups were significantly associated with covariates included in the multiple analyses. The results showed significantly higher all-cause, cardiovascular (CVD, cancer and other cause mortality for the low LTPA group but not for the moderate regular exercise and moderate exercise groups compared to the regular exercise group. Both the "Yes, but I need support" and the "No" fractions within the low LTPA group had significantly increased ORs of all-cause mortality compared to the "Yes, and I can do it myself" reference, while no significant associations were observed for CVD mortality. Physical activity promotion is particularly warranted in the low LTPA group.
目的是调查休闲时间体力活动（LTPA）与死亡率之间的关联，以及低LTPA组中增加LTPA的意愿与死亡率之间的关联。2008年，一份公共卫生调查问卷被发送给瑞典最南端18 - 80岁人群的分层随机样本，回复率为54.1%。2008年基线调查数据中的25464名受访者与死亡原因登记数据相链接，以创建一个有8.3年随访期的前瞻性队列。在逻辑回归模型中分析了LTPA、增加LTPA的意愿与死亡率之间的关联。18.4%的人进行规律运动（至少每周90分钟，导致出汗），23.2%的人进行适度规律运动（每周至少一次或两次，每次至少30分钟，导致出汗），44.3%的人进行适度运动（每周步行超过两小时或等量活动），14.1%的人报告LTPA较低（每周步行少于两小时或等量活动）。这四个LTPA组与多重分析中纳入的协变量显著相关。结果显示，与规律运动组相比，低LTPA组的全因死亡率、心血管疾病（CVD）、癌症和其他原因死亡率显著更高，但适度规律运动组和适度运动组并非如此。与“是的，而且我自己能做到”这一参照组相比，低LTPA组中“是的，但我需要支持”和“不”这两组的全因死亡率的比值比（OR）显著增加，而CVD死亡率未观察到显著关联。在低LTPA组中，促进体力活动尤其必要。
