Physical activity plays an important role in preventing further progres-sion of metabolic syndrome conditions to cardiovascular disease and type-2 diabetes. This study investigated physical activity disparities by socioeconomic status among metabolic syndrome patients. The fifth Korea National Health and Nutrition Examination Survey (2010–2012) data were analyzed (n=19,831). A revised definition of the US National Cholesterol Education Program Adult Treatment Panel III was used for screening metabolic syndrome patients. Using International Physical Activity Questionnaire, physical activity adherence was defined as par-ticipating in 150+ minutes of moderate-intensity physical activity, 75+ minutes of vigorous-intensity physical activity, or an equivalent combi-nation of moderate- to vigorous-intensity physical activity per week. Socioeconomic status was measured by level of education and house-hold income. Among metabolic syndrome patients, physical activity ad-herence rate of first (lowest), second, third, and fourth quartile house-hold income group were 28.31% (95% confidence interval [CI], 26.14–30.28%), 34.68% (95% CI, 32.71–36.70), 37.44% (95% CI, 35.66–39.25), and 43.79% (95% CI, 41.85–45.75). Physical activity adherence rate of groups with elementary or lower, middle-school, high-school, and college or higher education degree were 25.17% (95% CI, 22.95–27.54), 38.2% (95% CI, 35.13–41.00), 39.60% (95% CI, 38.24–41.77), and 36.89% (95% CI, 35.77–38.03), respectively. This study found that physical activity adher-ence rate was lower in socioeconomically disadvantaged metabolic syndrome patients, which may aggravate health inequity status of Ko-rean society.
