This study investigated the relationship between self-care and health-related behaviors such as medication use, dietary supplementation, dietary habits, and physical activity among Koreans aged 20–60 years.
Methods
Data from a total of 300 participants (150 men and 150 women) living in Seoul and Gyeonggi provinces in Korea were analyzed to assess the relationship between health behaviors and dietary supplements (DSs) related to self-care. Based on self-care levels, the participants were classified into three groups: low (LS, n = 124), medium (MS, n = 78), and high (HS, n = 98).
Results
DSs (P < 0.001), physical activity (P < 0.001), recognizing the perceived health benefits of self-care (P < 0.001), self-care when sick (P = 0.039), and the reasons for self-care (P = 0.028) differed among the self-care groups. Daily diet frequency (P = 0.001), breakfast frequency (P = 0.026), regular exercise (P < 0.001), DSs use rate (P < 0.001), DSs use frequency (P = 0.013), and total dietary behavior score (P < 0.001) also differed significantly depending on the degree of self-care. The degree of self-care was significantly and positively correlated with DSs intake (r = 0.377, P < 0.001), physical activity (r = 0.433, P < 0.001), and total dietary behavior score (r = 0.185, P < 0.01).
Conclusion
The results demonstrated that the degree of self-care was related to DSs, physical activity, and total dietary behavior scores in Korean adults. Additionally, self-care capacity should be increased through health-related behaviors based on health education programs.
