The purpose of this study is to investigate physical activity participation according to demographic, physical, and psychological variables in Korean adults.
Participants were divided into four groups (combined, aerobic only, resistance only, and neither) based on meeting the physical activity guideline using moderate and vigorous physical activity time and resistance exercise frequency from the Korea National Health and Nutrition Examination Survey 2017. The association between meeting the physical activity guidelines and demographic, medical, fitness, lifestyle, and psychological variables were analyzed using complex samples crosstabs and general linear model.
Of the total 5,820 Korean adults over age 19 years, 66.0% met neither guideline. Among demographic factors, gender, age, marital status, income, education level, occupation, and employment status were associated with meeting physical activity guidelines. Chronic disease prevalence, weight, waist circumference, body mass index, diastolic blood pressure, glucose, high density lipoprotein, triglyceride, hand-grip strength, resting heart rate, family history for chronic disease in the medical and fitness variables; frequency of drinking and breakfast, total calorie, water, protein, and fat intake in the lifestyle variables; and perceived stress, depression, suicide consideration, quality of life in the psychological variables were associated with meeting physical activity guidelines.
Most Korean adults participate in insufficient physical activity. Moreover, socially underprivileged, low-income, or people with poor physical and mental health conditions participated in relatively less physical activity. Our findings suggest that government and individual efforts are required to increase physical activity and to resolve health inequality in Korean adults.
