BACKGROUND: There is a dearth of knowledge regarding the relationship between engaging in moderate and vigorous physical activity and long-term sickness absence (LTSA), particularly among various population subgroups such as individuals of different ages or body mass indices. We aimed to evaluate the prospective associations of moderate and vigorous leisure-time physical activity with the risk of LTSA in the general working population.
METHODS: A prospective cohort study with a 2-year register follow-up was conducted, where 68,222 representative workers from Denmark completed a questionnaire about work environment, lifestyle, and health. Data on LTSA (≥6 consecutive weeks of sickness absence) were obtained from the Danish Register for Evaluation of Marginalization. We used Cox regression for the statistical analysis, adjusting for relevant confounding factors. We also performed age- and BMI-stratified analyses.
RESULTS: In the fully adjusted model, 2 to 4 hours per week of moderate activity (hazard ratios [HR] = 0.87; 95% CI, 0.77 to 0.99) and ≥2 hours per week of vigorous activity reduced LTSA risk compared with no physical activity. However, 2 to 4 hours per week of vigorous activity (HR = 0.84; 95% CI, 0.76 to 0.91) provided the greatest risk reduction. In the total sample, the complete absence of vigorous activity was associated with increased risk of LTSA (HR = 1.13; 95% CI, 1.05 to 1.22). In stratified analyses, the results were consistent for workers <50 years (HR = 1.14; 95% CI, 1.03 to 1.26), ≥50 years (HR = 1.13; 95% CI, 1.02 to 1.26), and those with a BMI ≥ 25 (HR = 1.16; 95% CI, 1.06 to 1.28). The complete absence of moderate activity was not associated with LTSA.
CONCLUSION: Vigorous leisure-time physical activity appears to be more important than moderate activity to prevent LTSA.
