Objectives: This study was performed to identify and find the clustering of healthy behaviors and the factors related to the clustering among Korean adults aged 19-64.
Methods: The data of 9,519 Korean adults aged between 19 and 64 years who participated in the 6th Korea National Health and Nutrition Examination Survey were used as the analysis target. Following the recommendation of the Health Plan 2020 for health-promoting lifestyle, four variables, including nonsmoking, moderate drinking, sufficient physical activity, and healthy diet, were used in the study. The obtained data were classified into five groups according to the number of indicators they practiced ranging from “0” for “not practicing at all” to “4” for “practicing all four parameters.” The multinomial logistic regression analysis was performed to analyze the relationships among demographic characteristics, health-related characteristics, and clustering of healthy behaviors.
Results: The results showed that only 3.9% of the subjects were practicing all four indicators of healthy behaviors. The significant elements of healthy behaviors clustering included sufficient physical activities for males, and non-smoking, moderate drinking, and healthy diet for females.
The related factors with clustering healthy behaviors by multinominal logistic regression analysis were higher for “females, the elderly, people with higher level of education, people with higher household income, people with diabetes, and people who perceive their subjective health status is good.
Conclusions: In order to spread the practice of healthy behaviors, multiple interventions are more effective than individual health behaviors.
In addition, considerable attention should be given to people other than females, advanced age, people with diabetes, and people who perceive their subjective health status to be good.
