Abstract

The fat soluble itamin D is recognized as the sunshine vitamin and it is considered more of a hormone than a Vitamin. The increasing prevalence of vitamin D deficiency in different parts of India in all age groups including neonates, school children, pregnant/lactating women, adult males and females residing in rural and urban India. The daily requirements of Vitamin D of body cannot be fulfilled by only food intake as the presence of Vitamin D in daily Indian food is very less in amount. But, the human body can synthesize Vitamin-D from sunlight exposure. This study was carried out in Kolkata to identify and address the role of Sunlight exposure in elevation of Vitamin-D level as well as the role of demographic factors like age, sex, caste and socio economic scale for the same. In this study 100 samples were taken who were suffering from Hypovitaminosis D (Lack of Vitamin D). Among them other 50 were treated as the case group (were in recommended diet and sun light exposure) and rest of the 50 were treated as the control group (without any suggestion).After 3 months when again blood test were done to measure the 25-hydroxy vitamin Dlevel which is the most accurate way to measure how much vitamin D is in our body, it was found that samples with diet and sunlight exposure improved significantly to those whom were not given any suggestion. The normal range is 30.0 to 74.0 nanograms per millilitre (ng/ml).The test is also alternatively known as 25-OH vitamin D test / Calcidiol / 25-hydroxycholecalciferol test. After the study, it is also found that maximum number of women staying at home as well as the geriatric subjects with low sun exposure suffer from bone ache, tingling effect at extremities due to low Vitamin D level. After the research work was completed it had been found that according to Statistical analysis, there is a correlation between the diet and sunlight exposure with the and improvement of Vitamin D level. Data was were analyzed using SPSS (version 18). One way ANOVA was used to study the factors affecting elevation of Vitamin-D level. The factors (Omit one full stop)which were significantly associated with elevation of Vitamin-D level were age (p0.05), sex (p0.05), caste (p0.05) and Socio economic level (p0.05).
