Objectives: This study aimed to investigate the association between vitamin D deficiency and the risk of diabetes mellitus, and also examined whether their association is differed by sex and age. Methods: We analyzed the data from 28,135 subjects ${\geq}20years$ old who were registered for the Korea National Health and Nutrition Examination Survey (KNHANES) 2008-2014. Vitamin D was measured using serum 25-hydroxyvitamin D (25(OH)D) concentrations. Results: After adjusting for potential confounders (age, sex, education, income, total energy intake, smoking, physical activity, body mass index, and waist circumference), lower vitamin D was dose-dependently associated with a higher risk of diabetes mellitus (p-trend=0.004). When compared with the sufficient group (25(OH)D ${\geq}30ng/mL$), the severe deficient group (25(OH)D <10 ng/mL) had 1.46 (95% CI 1.11-1.94) odds ratio for the risk of diabetes mellitus. This association was markedly strong in men and adults aged ${\geq}40$, whereas no significant association was observed in women and adults aged <40. Conclusions: We found that vitamin D deficiency may be associated with an increased risk for diabetes mellitus in Korean adults. Our findings suggest that intake of higher vitamin D may help reduce the risk of diabetes mellitus.

Objectives Our purpose of this study was to evaluate the association between depression, stress, and obesity indexes. Methods This study was performed in 110 healthy overweight and obese(BMI${\geq}23\;kg/m^2$) women in Korea. Subjects underwent abdominal CT(computed tomography) scanning and were asked to complete Beck depression inventory(BDI), social readjustment rating scale(SRRS), and stress response inventory(SRI) questionnaires. Weight, body-mass index(BMI), waist circumference(WC), and waist-hip ratio(WHR) were evaluated. Subjects were given written consent and this study was performed under permission of institutional review board of KyunHee University Hospital at Gangdong. Results 1. BDI and SRI were significantly correlated with VFA(visceral fat area)(p<0.05). However, other obesity indexes were not significantly correlated with BDI and SRI(p>0.05). 2. SRRS was not significantly correlated with all obesity indexes(p>0.05). Conclusions This study suggests that depression and stress might be correlated with visceral fat, and this result would be helpful for planning a treatment schedule of obese patients with depression or stress in the clinic.

This study was conducted to compare the nutritional status, nutrient intakes, and chronic disease risks of Chinese elderly people. MNA (Mini Nutritional Assessment) developed for elderly people was used to determine their nutritional status. In this study, participants consisted of 148 urban residents aged 65 years and over residing in three cities in Shandong Province, China. Participants were 67 (45.3%) men and 81 (54.7%) women, and average age was 72.8 years. According to MNA score, 77.7% of participants were 'well nourished', 22.3% were 'at risk of malnutrition', and 2% were 'malnourished'. Nutritional status was divided into two groups by MNA score as 'well nourished' and 'malnourished', which was formed with the combination of 'at risk of malnutrition' and 'malnourished'. Compared with the well nourished group, the malnourished group was older, and physical status indicators such as weight, BMI (Body Mass Index), and calf circumference of the malnourished group were much smaller. The malnourished group had higher prevalence rates of heart disease and stomach disorders while the well nourished group had a higher rate of hypertension. There was no significant difference between the malnourished group and well nourished group in nutritional intake below Chinese DRIs (Dietary Reference Intakes) among elder males. A higher proportion of elder females showed insufficient intakes of energy, protein, vitamin A, vitamin E, and zinc in the malnourished group compared to the well nourished group. The INQ (Index of Nutrition Quality) of calcium, magnesium, zinc, iodine, and most vitamins was less than 1 in both the malnourished and well nourished groups.

Purpose: This study aimed to evaluate the utility of acanthosis nigricans (AN) severity as an index for predicting insulin resistance in obese children. Methods: The subjects comprised 74 obese pediatric patients who attended the Department of Pediatrics at Chosun University Hospital between January 2013 and March 2016. Waist circumference; body mass index; blood pressure; fasting glucose and fasting insulin levels; lipid profile; aspartate transaminase, alanine transaminase, glycated hemoglobin, C-peptide, and uric acid levels; and homeostatic model assessment insulin resistance (HOMA-IR) and quantitative insulin check sensitivity index (QUICKI) scores were compared between subjects with AN and those without AN. Receiver operating characteristic curves were used to investigate the utility of the AN score in predicting insulin resistance. HOMA-IR and QUICKI were compared according to AN severity. Results: The With AN group had higher fasting insulin levels ($24.1{\pm}21.0\;mU/L$ vs. $9.8{\pm}3.6\;mU/L$, p<0.001) and HOMA-IR score ($5.74{\pm}4.71$ vs. $2.14{\pm}0.86$, p<0.001) than the Without AN group. The AN score used to predict insulin resistance was 3 points or more (sensitivity 56.8%, specificity 83.9%). HOMA-IR scores increased with AN severity, from the Without AN group (mean, 2.15; 95% confidence interval [CI], 1.72-2.57) to the Mild AN (mean, 4.15; 95% CI, 3.04-5.25) and Severe AN groups (mean, 7.22; 95% CI, 5.08-9.35; p<0.001). Conclusion: Insulin resistance worsens with increasing AN severity, and patients with Severe AN (AN score ${\geq}3$) are at increased risk of insulin resistance.

This study aimed to develop basic pants patterns reflecting somatotype characteristics of the women in their 20s. In order to develop basic pants patterns for women in their 20s, wearing tests were conducted. With the results of wearing tests, drafting methods were applied by using regression equation for the parts that were found to improper. For the parts where regression equation was not applicable, the results of wearing tests were applied. The results and the conclusion of development of basic pants patterns for women in their 20s were as follows. The waist height was applied for the regression equations of waist to hip length, crotch length, and knee length, and the hip circumference was applied for the regression equations of front leg opening. Also, back leg opening, front knee width and back knee width were calculated based on the front leg opening. For the waistline the ease of 2cm was added, and for the hipline the ease of 4cm was added. H/16 - 1cm was applied for the drafting of front crotch width, and H/8 was applied for the drafting of back crotch width. Pants patterns for women in their 20s on the methods mentioned above were tested for the $2^{nd}$ research wearing tests, and they received good ratings on the items and demonstrated that the developed pants patterns had excellent body fit.

Current reports suggest that obesity is a serious global health issue. Emerging evidence has predicted strong links between obesity and the human gut microbiota. However, only a few such studies have been conducted in Asia, and the gut microbiota of lean and obese adult Asians remains largely unexplored. Here, we investigated the potential relationship between gut microbiota, body massindex (BMI), and metabolic parameters in adults from Thailand, where obesity is increasing rapidly. Fecal and blood samples were collected from 42 volunteers who were allocated into lean, overweight, and obese groups. The fecal microbiota was examined by quantitative PCR analysis. Bacteroidetes, Firmicutes, and Staphylococcus spp. and methanogens were most abundant in lean volunteers. Overweight volunteers majorly harbored Christensenella minuta and Akkermansia muciniphila, ${\gamma}-Proteobacteria$, and bacteria belonging to the genus Ruminococcus. Methanogens and bacteria belonging to the phylum Bacteroidetes were negatively correlated with adiposity markers (BMI and waist circumference), but positive correlated with high-density lipoprotein, suggesting that they can be used as leanness markers. While some of our results agree with those of previous reports, results regarding the contributions of specific taxa to obesity were inconsistent. This is the first study to report the adult gut microbiota in Southeast Asian populations using molecular techniques and biochemical markers and provides a foundation for future studies in this field.

This study was conducted to investigate the bone mineral density (BMD) and the anthropometric measurements, socioeconomic factors, family history of osteoporosis and other environmental factors affecting BMD in children. One hundred sixty children (80 males, 80 females) in second grade of elementary school in Seoul were recruited; the mean age was 7.7 $\pm$ 0.47 years. Bone mineral density was measured in the lumbar spine (LS), femoral neck (FN), femoral trochanter (FT), and Ward's triangle (WT) by Dual Energy X-ray Absorptiometry (DEXA). Socioeconomic factors, family history of osteoporosis, and other environmental factors were assessed by questionnaire. Bone mineral densities of LS, FN, FT, and WT were 0.677, 0.637, 0.618, and 0.658 g/$\textrm{cm}^2$. BMD of boys was higher than that of girls (LS: 0.685 vs. 0.669, FN: 0.660 vs. 0.614, FT: 0.632 vs. 0.604, WT: 0.678 vs. 0.639 g/$\textrm{cm}^2$). Anthrometric measurements (height, weight relative body weight, circumference of waist and hip) were positively correlated with BMD. With increasing family income, BMD of LS was significantly lowered, and negative correlation was observed between mother's age at birth of subject and the BMD of FN. And the BMD of children with a family history of osteoporosis was significantly lower. However BMDs were not different by educational level of parents, family pattern, delivery term, birth weight, and type of feeding. Further studies are needed to clarify the factors affecting BMD of children and earlier age, included infants and even prenatal life. If any association is revealed and persist until the attainment of peak bone mass, osteoporosis prevention programs are needed to be start very early in the life cycle.

This study was performed to investigate Apolipoprotein E phenotypes and the relationship among lipid levels, nutrient intakes, lifestyles and risk factors between subjects with and without hyperlipidemic risk. The data were collected from 675 industrial male workers who had completed annual medical examination. Compared to the normal group, the hyperlipidemic risk group in Apo E3 and E4 had significantly higher BMI (p < 0.05) and showed significantly higher body fat (%), waist circumference and WHR in all types of Apo E (p < 0.05). In addition, the hyperlipidemic risk group had significantly higher total cholesterol, LDL-cholesterol, triglyceride and AI than the normal group in all types of Apo E (p < 0.05). Intakes of protein, calcium, phosphorus, iron, vitamin A, vitamin B1, vitamin B2, vitamin C and niacin in Apo E3 were significantly lower in the hyperlipidemic risk group than in the normal group (p < 0.05). In the logistic regression analysis, after adjustment for other factors, Apo E2 + E4, waist and WHR were the significant risk factors associated with hyperlipidemia, but protein intakes were associated with significantly lower risks of hyperlipidemia (p < 0.05). In conclusion, genetic factor (Apo E2 or Apo E4), anthropometric index and nutrient intake seem to influence hyperlidemic risk. Further studies and efforts will be needed to evaluate the independent relationships among hyperlipidemic risk factors.

Purpose: To compare histopathologic findings of patients who underwent transurethral resection of a bladder tumor (TUR-B) between groups with and without the metabolic syndrome. Materials and Methods: We retrospectively analyzed data of 535 patients who underwent TUR-B in our department between October 2005 and March 2011. All patients had primary urethelial cell carcinoma (UCB). Histologic stage, grade, the presence of hypertension, diabetes mellitus, body mass index (BMI), waist circumference, HDL and trigliseride levels were evaluated. The TNM classification was used, with Ta tumor accepted as lower stage and T1 and T2 tumors as higher stage bladder cancers. Also, the pathological grading adopted by the 2004 World Health Organization grading system were applied. Non-invasive papillary urothelial neoplasms of low malignant potential were regarded as low grade. Results: Among the total of 509 patients analyzed in our study, there were 439 males (86.2%) and 70 females (13.8%). Metabolic syndrome was significantly associated with high histologic grade, and high pathologic stage (p<0.001). Conclusions: The patients with metabolic syndrome were found to have statistically significant higher T stage and grade of bladder cancer. Further studies with more patients are needed to confirm our study.
