Prognoses for adults with diabetes are likely to improve with increased moderate physical activity, translating to lower death rates from cardiovascular disease and all causes, according to findings from a study in Great Britain published in Diabetes Care.
Patients with type 1 and type 2 diabetes were drawn from representative general population samples from the Health Survey for England and Scottish Health Survey conducted between 1997 and 2008. Researchers looked at 3,038 participants aged ≤50 years at baseline to examine associations between specific types of physical activity and all-cause and cardiovascular disease (CVD) mortality.
Data were collected on self-reported frequency, duration and intensity of participation in sports and exercise, walking and domestic physical activity. Researchers recoded specific physical activity types into intensity levels based on a ratio of work metabolic rate to a metabolic rate at rest of 1.0 and calculated sex-specific medians of time spent in each type of activity. Patients were followed up for 75 months for all-cause and CVD mortality, with type-specific associations examined through Cox proportional hazards regression.
Of the participants, 40% met the physical activity recommendation guidelines and 33% reported no physical activity. Those who reported some activity, but below the recommended amount, or who met the physical activity recommendations had a 26% (95% CI, 39-11) and 35% (95% CI, 47-21) lower all-cause mortality, respectively, compared with those who were inactive.
Sports and exercise and above-average levels of walking were inversely associated with all-cause, but not CVD, mortality. Domestic physical activity was not associated with mortality.
