Association between domain-specific physical activity and diabetes in Korean adults

Abstract

This study aimed to investigate the association between domain-specific physical activity (PA) and diabetes in Korean adults. We analyzed 26,653 men and women (aged > 18 years) from the Korea National Health and Nutrition Examination Survey (2014–2018). PA was measured using a validated Global PA Questionnaire. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) after adjustment for various confounders. Transport PA accounted for the majority of total PA (46%, men; 58%, women), followed by leisure-time PA (30%; 22%) and work PA (24%; 20%). In men, ORs (95% CI) of diabetes comparing ≥ 600 metabolic task of equivalent (MET)-min/week vs. no activity were 0.82 (0.71–0.95) for leisure-time PA, 0.85 (0.75–0.96) for transport PA, and 0.88 (0.78–0.99) for leisure-time + transport PA. In women, ORs (95% CI) of diabetes comparing the same groups were 0.73 (0.60–0.89) for leisure-time PA, 0.97 (0.85–1.10) for transport PA, and 0.88 (0.78–1.00) for leisure-time + transport PA. However, work PA showed no association with diabetes. In conclusion, leisure-time PA was inversely associated with diabetes in both men and women, while transport PA was inversely associated only in men. But work PA was not associated with diabetes in Korean adults.

Physical activity, sedentary behavior, and the risk of type 2 diabetes: A two-sample Mendelian Randomization analysis in the European population

“…However, the link between PA and T2DM may not always be plausible, and it may be influenced by gender and the kind of PA. According to a study in Korean adults, wsorking PA was not associated with T2DM risk, whereas transport PA was solely linked to T2DM in males ( 9 ). One previous MR study reported that objectively measured average or vigorous physical activity and SB are not associated with the risk of T2DM ( 16 ).…”

Comparing domain- and intensity-specific physical activity in coronary heart disease and non-CHD individuals

“…Physical activity domains (i.e., leisure, work, and transportation) may have varying associations with CHD. Leisure activity has an inverse linear association with CVD risk factors and mortality 22 , 23 . Associations of other physical activity domains with cardiovascular health remain less clear.…”

Understanding of the Single-Item Physical Activity Question for Population Surveillance

“…Epidemiological evidence points to a stronger protective association for leisure-time activity and nonutilitarian transport than other domains of activity in terms of all-cause mortality 29 and chronic disease incident risk. [30][31][32] This suggests that leisure-time PA, and possibly active transport, should be measured specifically in surveillance systems. Furthermore, occupational activity sometimes shows a paradoxical relationship with health outcomes, 33 and the independent benefits of domestic activity are not known.…”
