Introduction
Obesity is identified by the World Health Organization as a global epidemic leading to considerable public health issues. Body image perception has been known to play an important role in body weight management. For all people, negative body image perception is fairly common and has deleterious physical effects and emotional distress. This study examined the 5th South Korea National health and Nutrition Examination Survey and analyzed data of aged 19 to 64 years about body image perception and actual weight.
Methods
This study used the South Korea National Health and Nutrition Examination Survey from 2014-2017(n=21,326). Epidemiology of the study sample was classified by sex, age, annual income, education level, and presence of depression (Table 1). Furthermore, the study sample was grouped into 5 categories by each individual’s Body Mass Index × Subjective Body Recognition (BMI × SBR). The groups were analyzed according to level of physical activity (Table 2).
Results
In all exercise intensity, there were significantly higher exercise time in male (p<.001). There were significant difference in the order of 20-39yr, 40-64yr and ≥65yr in high intensity activity and 20-39yrs, 40-64yrs significantly engaged in moderate intensity activity compared to those ≥65yr (p<.001, p<.001 respectively). Both higher house-hold income and education level showed significant positive correlation with high and moderate intensity physical activity (p<.001, p<.001 respectively). Low house-hold income group showed less walking time than other groups (p<.001), and education level analysis showed more walking in ≥college, high school, middle school groups than in the ≤elementary school group (p<.001). Study sample without depression reported significant more high and moderate intensity activity (p=.042, p<.001 respectively). (Table 1). High intensity physical activity according to BMI × SBR showed significant more high intensity activity in groups a, c, d, e than in group b (p<.001) and showed significant more physical activity in groups c, d than in group b in moderate intensity activity (p<.001) (Table 2).
Conclusion
In our study, it can be seen that female, the older age, the lower annual income and education level people have lower exercise time. In 5 groups categorized by body perception and BMI, BMI(underweight)×SBR(underweight) group has lower exercise time than other groups. In addition, the group with matching BMI and SBR except BMI (underweight) × SBR (underweight) group has a higher mean exercise time than the mismatching group. From these results, we can compare the conditions of exercise-vulnerable group suggested by international organization with conditions of South Korea. Furthermore, it is suggested that these difference will be a necessary for the development of exercise programs targeting exercise-vulnerable groups in South Korea.
