Association between daily protein intake and cardiometabolic risk factors and metablic syndrome in Korean elderly women: Based on the Korea National Health and Nutrition Examination Survey, 2009~2013

Background: The Rrecommended daily aAllowances (RDA) of for protein is increasing in recent studieshas increased in recent studies. However, virtual protein intake is lower than the RDA in the majority of Korean elderly Korean women. ObjectPurpose: This study was performed to evalauate the relationship between protein intake, and cardiometabolic risk factors, and metabolic syndrome in Korean elderly Korean women group. Methods: This study used the data from Korea National Health and Nutrition Survey administered from for 5years in 2009~2013. We performed multivariate analysis for on the association of between protein intake with and cardiometabolic risk factors including body weight, weight circumference, blood pressure, glucose, triglycerides, and HDL. We controlled for age, physical activity, energy intake, carbohydrate intake, total fat intake, smoking, and alcohol consumption. Then weWe then performed logistic regression analysis to study of the associateion with metabolic syndrometo assess association with metabolic syndrome. Results: Protein intake was inversely associated with BMI and, weight circumference, ,whereas a positive association was observed between protein intake and HDL cholesterol, especially in the normal weight group. Protein intake also haswas also association associated with metabolic syndrome. Conclusion: In this study, protein intake is was related associated with cardiometabolic risk factors and metabolic syndrome. We recommend sufficient protain protein intake in elderly women to decrease cardiometabolic risk factors and metabolic syndrome.ope

Association between Body Mass Index, Waist Circumference and Prevalence of Microalbuminuria in Korean Adults of Age 30 Years and Older without Diabetes, Hypertension, Renal Failure, or Overt Proteinuria: The 2013 Korean National Health and Nutrition Examination Survey

BACKGROUND: Microalbuminuria and obesity markers are known risk factors for cardiovascular or renal disease. This study aimed to evaluate the prevalence of microalbuminuria according to body mass index (BMI) and abdominal obesity criteria. METHODS: The study subjects included 3,979 individuals aged 30 years or older who did not have diabetes, hypertension, renal failure, or overt proteinuria, from among those who participated in The Korean National Health and Nutrition Examination Survey in 2013, a cross-sectional, nationally representative, stratified survey. Microalbuminuria was defined as a urinary albumin to creatinine ratio of 30 to 300 mg/g. BMI and waist circumference were classified according to the Asia-Pacific criteria. RESULTS: The prevalence of microalbuminuria was found to be 5.1%. In the normoalbuminuria group, 3.4%, 41.7%, 24%, 27.6%, and 3.2% of participants were included in the underweight, normal, overweight, obesity 1, and obesity 2 groups, respectively. These percentages in the microalbuminuria group were 7.1%, 34.5%, 19.2%, 28.6%, and 10.6%, respectively (P<0.001). The waist circumference in men was 21.4% in the normoalbuminuria group and 36.5% in the microalbuminuria group (P=0.004). Logistic regression analyses were performed to evaluate the relationship between the presence of microalbuminuria and BMI or waist circumference groups. The risk of microalbuminuria was significant only in the underweight group (odds ratio, 13.22; 95% confidence interval, 2.55-68.63; P=0.002) after adjusting for confounding factors, abdominal obesity was not significantly associated with microalbuminuria. CONCLUSION: The prevalence of microalbuminuria in a general population in Korea was associated with underweight in men and was not associated with waist circumference in either men or women.ope

Association between sleep duration and bone mineral density density in Korean adults over 18years old: Based on the Korea National Health and Nutrition Examination Survey, 2010

Background: Sleep duration is associated with many diseases, yet few studies have been performed on the association between sleep duration and bone mineral density(BMD) in Korea. In this study we investigated the association between sleep duration and bone mineral density in adults over 18 years of age. Methods: Subjects of this study were adults over 18 years of age who responded to a questionnaire on sleep duration and underwent BMD measurement by dual X-ray absorptiometry. Comprehensive data on the study sample was obtained from the Korean National Health and Nutrition Examination Survey(KHANES) conducted in 2010. Age- and sex-stratified multiple regression analyses were conducted with adjustment for possible confounding factors. Results: There was an inverse, dose-dependent association between sleep duration and BMD measured in the total femur, femur neck, lumbar spine and total bone in both women over 50 years of age and men between 30 and 49 years of age. Sex-stratified multiple regression analysis adjusted for age and body mass index revealed a negative correlation between sleep duration and BMD in the total femur and femur neck in both genders over 50 years of age, as well as in women between ages 30 and 49. Initial significance disappeared after adjustment for additional covariates including smoking, alcohol, and exercise. Conclusion: Significant variations in regional BMD with sleep duration were observed among women and men between ages 30 and 49. Prolonged sleep duration appears to be a risk factor for low bone mineral density. Thus, adequate sleep duration is important for preventing osteoporosisope
