缺乏身体活动是一个与死亡风险增加有关的重大公共卫生问题。然而，人们对剧烈运动是否比低强度运动更有利于降低死亡风险知之甚少。本研究的目的是在考虑社会人口学和健康相关因素作为协变量的情况下，研究中年女性和男性休闲时间体育活动的强度和量与全因死亡率之间的关系。2000- 2002年在赫尔辛基市40 - 60岁雇员中收集的问卷调查数据（N = 8960）与死亡率登记数据（74%同意联系）相关联，平均随访时间为12年。该分析包括6429名受访者（79%为女性）。参与者根据体力活动强度被分为三组：中低、中高和剧烈。身体活动量按类别分为三组。采用Cox回归分析计算全因死亡率的风险比（HR）和95%置信区间（CIs）。在随访期间，205名参与者死亡。闲暇时间的体育活动与降低死亡风险有关。调整协变量后，剧烈组（HR = 0.54, 95% CI 0.34-0.86）与低中度组相比，死亡率风险降低，而高中度组的死亡率风险降低（HR = 0.72, 95% CI 0.48-1.08）不太明显。调整身体活动量并不会影响对得分的估计。更多的闲暇时间身体活动也与降低死亡风险有关；然而，调整协变量和体力活动强度解释了差异。对于参加一些体育活动的健康中年妇女和男子来说，剧烈运动可能会进一步提供健康益处，防止过早死亡。
Physical inactivity is a major public health problem associated with increased mortality risk. It is, however, poorly understood whether vigorous physical activity is more beneficial for reducing mortality risk than activities of lower intensity. The aim of this study was to examine associations of the intensity and volume of leisure-time physical activity with all-cause mortality among middle-aged women and men while considering sociodemographic and health related factors as covariates. Questionnaire survey data collected in 2000-02 among 40–60-year-old employees of the City of Helsinki (N = 8960) were linked with register data on mortality (74% gave permission to the linkage) providing a mean follow-up time of 12-years. The analysis included 6429 respondents (79% women). The participants were classified into three groups according to intensity of physical activity: low moderate, high moderate and vigorous. The volume of physical activity was classified into three groups according to tertiles. Cox regression analysis was used to calculate hazard ratios (HR) and 95% confidence intervals (CIs) for all-cause mortality. During the follow up 205 participants died. Leisure-time physical activity was associated with reduced risk of mortality. After adjusting for covariates the vigorous group (HR = 0.54, 95% CI 0.34–0.86) showed a reduced risk of mortality compared with the low moderate group whereas for the high moderate group the reductions in mortality risk (HR = 0.72, 95% CI 0.48–1.08) were less clear. Adjusting for the volume of physical activity did not affect the point estimates. Higher volume of leisure-time physical activity was also associated with reduced mortality risk; however, adjusting for the covariates and the intensity of physical activity explained the differences. For healthy middle-aged women and men who engage in some physical activity vigorous exercise may provide further health benefits preventing premature deaths.
