Objectives
This study evaluated the dietary habits and health behaviors of Korean adults according to their physical activity.
Methods: Adults aged 19~64 years, who participated in the 2016~2018 National Health and Nutrition Examination Survey, were enrolled in this study. The subjects were classified into the physical inactivity group, aerobic physical activity group, strength exercise group, and combined exercise group.
Results: Significant differences in skipping breakfast, frequency of eating out, dietary supplements, and alcohol drinking status were observed among physical activity groups (P < 0.001). The combined exercise group had the highest % KDRI of protein, vitamin A, thiamin, riboflavin, niacin, calcium, potassium, and iron (P < 0.001). The physical inactivity group had the highest obesity rate (35.1%), and they perceived their body image type to be obese. In the combined exercise group, 47.8% of respondents said they were in good health (P < 0.001). The health-related quality of life score of the physical inactivity group was the lowest, with a score of 0.94. The metabolic syndrome risk rate of the combined exercise group was lower at 0.62 times (95% CI, 0.51-0.75) than the physical inactivity group.
Conclusions: The physical activity type was associated with metabolic syndrome.
These results can be useful for supporting dietary education and physical activity programs for adults.

% KDRI of nutrient intake according to physical activity type (*** P < 0.001, P-values are from ANOVA test). All the estimates were produced to represent the Korean population using sample weight for the analysis of health and nutrition survey and SAS SURVEY procedure was used to account for multistage sampling and unequally weighted design. 1) A person who do not act physical activity 2) A person who act aerobic physical activity of moderate intensity physical activity at least 150 minutes a week 3) A person who act strength exercise at least 2 times a week 4) A person who act aerobic physical activity and strength exercise
