Background: The relationship between a low vitamin D level and depression has been demonstrated repeatedly. We assessed the correlation between vitamin D status and the prevalence of depression according to body weight status. Methods: Data from 1,747 participants who took part in the 2014 Korean National Health and Nutrition Examination Survey were analyzed. The presence of depression was identified by the brief, self-reported Patient Health Questionnaire-9 (PHQ-9), vitamin D status was defined based on the serum 25-hydroxyvitamin D [25(OH)D] level, and body weight status was expressed as the body mass index. Results: After adjusting for potential confounding factors, participants in the vitamin D deficiency group (odds ratio [OR], 2.70; 95% confidence interval [CI], 1.01-7.20) and severe deficiency group (OR, 2.89; 95% CI, 1.04-8.00) were significantly more likely to experience depression. Multivariate logistic regression analyses indicated that among the participants with overweight or obesity, those in the vitamin D deficiency group were 3.71 times more likely than those in the sufficiency group (OR, 3.71; 95% CI, 1.08-12.74) to experience depression. Conclusion Our findings suggest a significant association between low vitamin D levels and depression in adults with overweight or obesity. Further studies are needed to elucidate the association between vitamin D status and depression according to body weight status.

This study was conducted to provide basic information on the nutritional status and health status of the rural elderly. The food intake, food habits and others health related factors were surveryed by interview method. The subjects was 200 people(71 male, 129 female) aged over 65 year in the Han-an area. The obtained results as follows; Their average age is 73.5+/-5.6. Mean height and weight of elderly men were 163 cm and 58.1 kg. respectively and 148.7 cm and 50.0 kg for women. The regularity appetite and frequency of eating snacks and eating out were higher in men than in women. The favorite snacks for men were alcohol fruit coffee and for women was fruit, candy, cookies and coffee. The daily alcohol drinking and smoking ration were 50.0%, 60.6% for men, respectively and 14.0%, 24.8 % for women. The nutritional intake ratio to RDA of men was significantly higher than women. Especially, the intakes of energy, Ca, Vit.A, Vit B1, Vit B2 niacin were extremely low in women. The frequency of alcohol intake was related to nutrient intake of women . There was a negative correlation between age. smoking rate and the nutritional intake. The pocket money, weight height appetite, and frequency of snacks showed a positive relation to nutritional intake. In conclusion the study shows that gender did influence food intake in the elderly, Food intake of women was extremely in deficit, because the most elderly rural women live alone. For successful aging. a program for rural elderly is needed on the govermment level, i.e actions to provide minimum economic life, food delivery and psychological/ physical health care through regional pubilc health centers.
