ABSTRACT
Purpose@#The purpose of this study was to examine the associations of aerobic physical activity and musclestrengthening exercise with mental health, respectively. Furthermore, the relationship between combined exercise with depression, stress, and suicidal thoughts was also examined. @*Methods@#The association between adherence to physical activity guidelines and mental health was analyzed among 27,268 adults who participated in the 2014– 2018 Korea National Health and Nutrition Examination Survey. Logistic regression was used to predict the relationship between adherence to physical activity guidelines and mental health. @*Results@#The odds ratio for depression and suicidal thoughts in groups that met both aerobic physical activity and muscle-strengthening exercise guidelines decreased by 27% (95% confidence interval [CI], 0.56– 0.94) and 40% (95% CI, 0.39– 0.93), respectively, compared to those that did not meet both. Stress awareness decreased by 22% (95% CI, 0.67– 0.90) in those who met muscular exercise guidelines, but did not meet aerobic physical activity guidelines. For those who met only the aerobic physical activity guidelines, stress awareness decreased by 12% (95% CI, 0.82 – 0.95). In addition, the odds ratio decreased by 29% (95% CI, 0.62 – 0.80) in groups that met both guidelines. @*Conclusion@#The most positive relationships between adherence to physical activity guidelines and mental health were found when both aerobic and muscular exercise guidelines were met.
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.
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 relationship between sedentary behavior measured by accelerometer and cardiovascular disease risk factors from Korea National Health and Nutrition Examination Survey 2014–2015. @*Methods@#The participants included in this study volunteered to wear accelerometer (n=1,407). Ordinal logistic regression was used to examine the relationship between sedentary time or sedentary breaks and cardiovascular disease risk factors. Odds ratios and 95% confidence intervals were calculated for the relationship. Covariates were sex, age, educational status, alcohol, smoking, socioeconomic status, body mass index, calorie intake, physical activity, and accelerometer wear time. @*Results@#The group with the most sedentary time had significantly greater odds of having dyslipidemia (odds ratio, 2.47; 95% confidence interval, 1.54–3.94) compared to the least. There were no other significant relationships between sedentary behavior (sedentary time, sedentary break) and risk factors. @*Conclusion@#The only significant relationship found in this study was that between sedentary time and dyslipidemia.
ABSTRACT
PURPOSE: The main purpose of this study was to compare the relationships between physical activity (measured using an accelerometer vs. self-reported) and cardiovascular disease risk factors. Differences in accelerometry physical activity between 10-minute bouts and total bouts were also compared.METHODS: Data originated from the Korea National Health and Nutrition Examination Survey. Logistic regression was used to predict cardiovascular disease risk from physical activity levels.RESULTS: Self-reported physical activity could not significantly predict the odds of having cardiovascular risk. However, the insufficiently active group classified according to the total-bout physical activity had significantly greater odds of having hypertension or prehypertension (odds ratio [OR], 1.35; 95% confidence interval [95% CI], 1.00–1.82), diabetes mellitus (OR, 1.77; 95% CI, 1.01–3.19), and dyslipidemia (OR, 1.65; 95% CI, 1.17–2.36) than the highly active group. Regarding the 10-minute bout physical activity, the inactive group had significantly greater odds of having only hypertension or prehypertension (OR, 1.67; 95% CI, 1.02–2.76) than the highly active group.CONCLUSION: Total-bout physical activity measured using an accelerometer could significantly predict the cardiovascular disease risk compared to 10-minute bout physical activity. However, self-reported physical activity could not significantly predict the cardiovascular disease risk.
