本研究的目的是检验体力活动的数量和强度是否与随后不同长度的病假期相关，以及这些关联在多大程度上可以通过社会经济地位、体重指数 (BMI) 和身体健康功能来解释。基线数据是通过2000-2002年对赫尔辛基市40-60岁雇员（n=6465，79%为女性）的问卷调查收集的。因病缺勤数据来自雇主登记册（平均随访时间 3.9 年）。使用泊松回归分析检查了体力活动与较短（< 14 天）和较长（> 14 天）病假时间的关联。体力活动量与因病缺勤的相关性较弱且有些不一致。然而，系统地进行剧烈活动的男性和女性会降低因病缺勤的风险，而相同量的中等强度体力活动并不会降低因病缺勤的风险。调整体重指数，特别是身体健康功能削弱了这些关联，之后这些关联就失去了统计学意义。结果表明，剧烈的体力活动与因病缺勤有关，并可能有助于提高工作能力。
The aim of this study was to examine whether the volume and intensity of physical activity are associated with subsequent sickness absence spells of different lengths, and how much of these associations can be explained by socioeconomic position, body mass index (BMI) and physical health functioning. Baseline data were collected by questionnaire surveys in 2000-2002 among 40-60-year-old employees of Helsinki City (n=6465, 79% women). Sickness absence data were derived from the employer's registers (mean follow-up time 3.9 years). Associations of physical activity with shorter (< 14 days) and longer (> 14 days) sickness absence spells were examined, using Poisson's regression analysis. The volume of physical activity was weakly and somewhat inconsistently associated with sickness absence. However, men and women who were vigorously active systematically had reduced risk of sickness absence, whereas the same volume of moderately intensive physical activity did not reduce the risk of sickness absence. Adjusting for BMI and in particular physical health functioning attenuated these associations, after which the associations lost statistical significance. The results suggest that vigorous physical activity is associated with sickness absence and may contribute to better work ability.
