physical activity promotes healthy aging. However, little is known about the relationship between physical activity levels and healthy and chronic disease-free life expectancy (LE). The study aim was to examine healthy and chronic disease-free LE between ages 50 and 75 and across various levels of physical activity by sex and different occupational statuses.
overall, 34,379 women (mean age 53.2 (SD 2.9) years) and 8,381 men (53.6 (SD 3.2) years) from the Finnish Public Sector study were categorized into five physical activity levels (inactive to vigorously active) according to self-reported physical activity and into three occupational statuses at the first observation point. Partial LE between ages 50 and 75 based on discrete-time multistate life table models was defined using two health indicators: healthy LE based on self-rated health and chronic disease-free LE based on chronic diseases. The average follow-up time for health indicators was 6.8 (SD 5.2) years.
a clear dose-response relationship between higher physical activity levels and increased healthy and chronic disease-free LE in men and women, and within occupational statuses was found. On average, vigorously active men and women lived 6.3 years longer in good health and 2.9 years longer without chronic diseases between ages 50 and 75 compared to inactive individuals. The difference in years in good health between vigorously active and inactive individuals was the largest in individuals with low occupation status (6.7 years).
higher levels of physical activity increase healthy and chronic disease-free years similarly in men and women, but more among persons with low than with high occupational status.
身体活动促进健康老龄化。然而，对于身体活动水平与健康和无慢性病预期寿命（LE）之间的关系知之甚少。本研究旨在通过性别和不同职业状况，检查 50 至 75 岁人群中不同身体活动水平之间的健康和无慢性病 LE。
总体而言，34379 名女性（平均年龄 53.2（2.9）岁）和 8381 名男性（53.6（3.2）岁）来自芬兰公共部门研究，根据自我报告的身体活动情况分为五个身体活动水平（不活动到剧烈活动），并在第一次观察点分为三种职业状况。基于离散时间多状态生命表模型的 50 至 75 岁之间的部分 LE 使用两个健康指标定义：基于自我报告健康的健康 LE 和基于慢性疾病的无慢性病 LE。健康指标的平均随访时间为 6.8（5.2）年。
发现男性和女性以及职业状况内，更高的身体活动水平与健康和无慢性病 LE 的增加之间存在明显的剂量反应关系。与不活跃的个体相比，剧烈活动的男性和女性在 50 至 75 岁之间健康状况良好的时间平均延长了 6.3 年，没有慢性疾病的时间延长了 2.9 年。与不活跃的个体相比，剧烈活动的个体与不活跃的个体之间健康状况良好的差异在职业地位较低的个体中最大（6.7 年）。
更高水平的身体活动同样可以增加男性和女性的健康和无慢性病年限，但在职业地位较低的人群中增加幅度更大。
