ABSTRACT
Purpose@#The purpose of this study was to identify the association between resistance exercise frequency, aerobic physical activity level, and health-related quality of life in Korean older adults from the seventh Korea National Health and Nutrition Examination Survey, 2018. @*Methods@#Complex samples logistic regression was used to examine the relationship between resistance exercise frequency, aerobic physical activity level, and health-related quality of life in Korean older adults. Odds ratio, covariate-adjusted odds ratio, and 95% confidence interval were calculated for the relationship. Covariates were age, sex, educational status, alcohol drinking, smoking, household income status, and body mass index. @*Results@#In all variables related to resistance exercise frequency and aerobic physical activity level, the group performing below the recommended level was significantly higher in odds ratio and covariate-adjusted odds ratio on EuroQol-5 Dimension index score of less than 1 (having problems with health-related quality of life) than the group performing above the recommended level. @*Conclusion@#The results of this study showed that performing above the recommended level of resistance exercise frequency and aerobic physical activity is associated with improved health-related quality of life in Korean older adults.
ABSTRACT
Purpose@#The purpose of this study was to examine the association between the levels of sedentary time, physical activity, and obesity in Korean older adults. @*Methods@#A cross-sectional analysis was performed on 1,396 Korean older adults aged 65 to 80 years from the Korea National Health and Nutrition Examination Survey 2018. Complex samples logistic regression was used to examine the relationship between the levels of sedentary time, physical activity, and obesity. @*Results@#The high sedentary group (≥ 8 hours/day) had significantly greater odds of having obesity than the low sedentary group (＜ 8 hours/day). But there was no statistically significant difference in odds of having obesity between the high active group (≥ 600 metabolic equivalent of task [MET]-minute/week) and the low active group (＜ 600 MET-minute/week). The high sedentary/low active group had significantly greater odds of having obesity than the low sedentary/high active group and the low sedentary/low active group. But there was no statistically significant difference in odds of having obesity compared to the high sedentary/high active group. @*Conclusion@#Higher sedentary time (≥ 8 hours/day) was associated with a higher risk of having obesity, independent of meeting higher physical activity level (≥ 600 MET-minute/week) in Korean older adults.
