<b>Background:</b> Information about the influence of regular physical activity on course chronic obstructive pulmonary disease (COPD) is scarce. A study was undertaken to examine association between and both hospital admissions for COPD all-cause specific mortality in subjects. <b>Methods:</b> From a population-based sample recruited Copenhagen 1981–3 1991–4, 2386 individuals with (according lung function tests) were identified followed until 2000. Self-reported at baseline classified into four categories (very low, moderate, high). Dates causes obtained from Danish registers. Adjusted associations using negative binomial Cox regression models, respectively. <b>Results:</b> After adjustment relevant confounders, subjects reporting moderate or high had lower risk admission during follow up period than those who reported very low (incidence rate ratio 0.72, 95% confidence interval (CI) 0.53 0.97). Low, levels associated an adjusted (hazard (HR) 0.76, CI 0.65 0.90) respiratory (HR 0.70, 0.48 1.02). No effect modification found sex, age group, severity, background ischaemic heart disease. <b>Conclusions:</b> Subjects perform some level have mortality. The recommendation that patients be encouraged maintain increase their should considered future guidelines, since it likely result public health benefit.
