RESUMO
Background@#Sedentary behavior is associated with increased cardiovascular disease (CVD) risk. We investigated this association of sedentary time and physical activity with increased 10-year CVD risk in Korean adults. @*Methods@#This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (2014–2017). In total, 14,551 participants aged 30–74 years (6,323 men, 8,228 women) were analyzed. The usual length of sedentary time per day was categorized into three groups (<6, 6–<9, or ≥9 h/d), and physical activity (metabolic equivalents [METs]∙min/wk) was categorized into two groups (low, <600 METs∙min/wk; moderate/high, ≥600 METs∙min/wk). Logistic regression analysis was performed to assess the association between sedentary time and increased CVD risk (predicted 10-year risk ≥10%). Adjusted variables were age, sex, body mass index, marital status, employment, household income, alcohol use, family history of CVD, and comorbidity (hypertension, diabetes, and dyslipidemia). @*Results@#The average sedentary time for the 14,551 participants was 7.49 h/d, with an average 10-year CVD risk of 9.58%. There was no significant association between sedentary time and increased 10-year CVD risk in the moderate/ high physical activity group. In the low physical activity group, sedentary time ≥9 h/d had a significant association with increased CVD risk (odds ratio [OR], 1.29; 95% confidence interval [CI], 1.04–1.62). However, when the sedentary time was <6 h/d, no significant associations were found (OR, 1.17; 95% CI, 0.92–1.49). @*Conclusion@#In the low physical activity group, reduction of sedentary time might be important for preventing increased CVD risk.
RESUMO
BACKGROUND: Dietary patterns have a significant impact on prognosis, recurrence, and survival in patients with cancer. This study investigated dietary patterns using the Diet Quality Index-International (DQI-I) in cancer survivors compared to those in the general population without cancer.METHODS: Using the Korea National Health and Nutrition Examination Survey VI data, cancer survivors were defined as those diagnosed with cancer more than 1 year before the survey. The associations between possible predictors and the DQI-I score were examined using t-tests and analysis of variance. Adjusted multiple linear regression analysis was performed to compare the differences in DQI-I scores between cancer survivors and controls.RESULTS: In univariate analysis of 9,351 subjects (433 cancer survivors and 8,918 controls), age, sex, body mass index, marital status, education level, income, residential area, smoking status, and alcohol consumption were associated with the DQI-I score (each P-value < 0.05). After adjustment, cancer survivors showed higher DQI-I scores than the controls (67.40±8.90 vs. 65.50±9.40, P-value=0.007). In subgroup analysis, cancer survivors within 5 years after cancer diagnosis showed higher DQI-I scores than the controls (68.70±8.30 vs. 65.50±9.40, P-value=0.034), whereas those who survived beyond 5 years post-diagnosis did not show significant differences from the controls (66.70±9.20 vs. 65.50±9.40, P-value=0.063).CONCLUSION: Cancer survivors within 5 years of cancer diagnosis showed better dietary patterns than those in the general population. However, the differences were not observed after 5 years post-diagnosis. To reduce the risks of second primary cancer and mortality, targeted inventions for dietary habits are necessary for long-term survivors of cancer.
