RESUMO
Objective@#Several studies suggested that heart rate variability (HRV) is a risk factor for metabolic syndrome. The objective of this study was to evaluate the association between HRV and metabolic syndrome among Korean adults. @*Methods@#We included 6,945 people who visited the Soonchunhyang University Cheonan Hospital Health Examination Center and tested HRV, from March 2016 to November 2019. Among them, 6,827 subjects were included. We excluded those who had a history of hypertension, diabetes, stroke, or other disease and excluded them from the omission of questionnaires. We examined HRV with machine WISE-8000 (MooYoo Instruments, Seongnam, Korea) and divided three groups of HRV results. The diagnosis of metabolic syndrome was made using criteria modified National Cholesterol Education Program Adult Treatment Panel III. Logistic regression analysis was used to calculate odds ratios between HRV results and metabolic syndrome. @*Results@#The odds ratio for metabolic syndrome in low HRV result was 2.87 (95% confidence interval [CI], 1.87–3.34) compared with high HRV result. After adjustment for age, smoking, alcohol consumption, and physical activity, the odds ratio for metabolic syndrome in low HRV result was also 3.37 (95% CI, 2.44–4.65) compared with high HRV result. @*Conclusion@#Low HRV result using WISE-8000 (MooYoo Instruments) showed an increased risk for metabolic syndrome. HRV was associated with an increased risk of metabolic syndrome in Korean adults.

RESUMO
BACKGROUND/OBJECTIVES: Recent studies showed vitamin D deficiency is linked to chronic diseases in addition to skeletal metabolism which could threaten the elderly. We analyzed health conditions and socio-demographic factors associated with vitamin D deficiency in community dwelling people aged 65 years and older. SUBJECTS/METHOD: Data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010 to 2012 were obtained. A total of 2,687 subjects aged 65 years and older were participated. The cutoff value of the Vitamin D deficiency was considered as serum 25-hydroxyvitamin D [25(OH)D] ≤ 20 ng/mL (50 nmol/L). RESULTS: The overall prevalence rate of vitamin D deficiency in the elderly was 62.1%. The factors such as female, obesity, metabolic syndrome, current smoker, and skipping breakfast were positively associated with vitamin D deficiency, but high intensity of physical activity and more than 9 hours of sleep duration were negatively associated with vitamin D deficiency (all P < 0.05). CONCLUSIONS: It is important that health professions know that the factors proved in this study are connected to vitamin D deficiency thus provide information and intervention strategies of vitamin D deficiency to old aged people.
