Background: Normal growth and development requires vitamin D, and its deficiency compromises long term health and increases the risk of chronic disease. Severe vitamin D deficiency include rickets, osteomalacia, osteoporosis, increased risk of fracture, tooth loss. Studies indicate that vitamin D insufficiency (less severe than deficiency) is associated with a wide range of illnesses and chronic conditions, including type 1 diabetes, hypertension, multiple sclerosis and many types of cancer. Currently world is facing an unrecognized and untreated pandemic of vitamin D deficiency. This study aims at showing the relation between Vitamin D status and obesity in adolescent children and to know the dietary factors, life style factors like physical activity contributing to overweight and obesity in adolescents.Methods: Study design: This is an observational study of 30 overweight and obese adolescents based on BMI were studied and their Vitamin D levels were assessed.Results: A total of 14(46.7%) overweight and 16(53.3%) obese adolescents Vitamin D levels were assessed. 20(66.7%) had vitamin D levels <20ng/ml that is in the deficiency range.4(13.3%) had in the insufficiency range (21-30ng/ml), 6(20%) had in the sufficient range. Results shows vitamin D levels were significantly less in obese and overweight adolescents.Conclusions: Study results confirm that Vitamin D deficiency or insufficiency is common to obese and overweight adolescents, this may help to explain the relationship between obesity and several chronic diseases that are associated with poor Vitamin D status.

Abstract Objectives To study the nutritional status and prevalence of RBC folate, Serum folate and vitamin D deficiency among adolescents. Methods A cross sectional pilot study was carried out among 96 adolescents visiting outpatient department for refraction at tertiary care hospital in North India. Anthropometric data was obtained for height in centimetres and weight in kilograms. A pretested questionnaire was used to capture quantitative data. Venous blood samples were collected where red blood cell (RBC), serum folate and serum Vitamin D concentrations were measured. Anaemia was defined as normal, mild, moderate and severe as Hb > 12gm/dl, 11–11.9 gm/dl, 8–10.9 gm/dl and < 8 gm/dl respectively. Serum folate deficiency was defined as serum folate < 7 nmol/l, and RBC folate deficiency and insufficiency were defined as RBC folate < 305 nmol/l and & < 748 nmol/l, respectively. Vitamin D deficiency, insufficiency and sufficiency was defined as 25(OH)D < 20 ng/ml, 20–29 ng/ml and ≥ 30 ng/ml respectively. Descriptive statistics and inferential statistics were used. Results Almost 46% of adolescents were malnourished (10.4% were underweight, 35.4% were overweight or obese) and mean BMI was 19.7 kg/meter2 however it did not differ significantly across gender. As compared to boys more girls were vegetarian by diet. The mean concentrations for Hb, serum folate and RBC folate were 12.7 (95% CI: 12.4, 13.0) gm/dl, 15.1 (95% CI 12.5, 17.7) nmol/L and 492.9 (95% CI 431.9, 553.9) nmol/L, respectively. Mean concentration for Hb was significantly different across gender (p – 0.0). Around 17% of adolescents were anaemic, 60% were deficient for serum folate and 79% were deficient for RBC folate. Mean serum vitamin D levels were 18 ng/dl (95% CI: 17.0, 22.3) no significant difference found across gender. A total of 62.5% were deficient and 28% were insufficient for vitamin D (ng/ml). Around 50% of the adolescents lack adequate sleep (<8 hours) and increase vitamin D levels were associated with increase sleep duration (r-0.02, p-0.02). Conclusions The nutritional status of adolescents in this study is poor and reflects a need to conduct a community-based study which can help in planning strategies to improve nutritional status during critical period of adolescence Funding Sources nil.

The Status

Background: Vitamin D deficiency is a common problem in many countries throughout the world. This study aimed at understanding the status of vitamin D deficiency in relation to age, gender, geography and season among relatively bigger numbers of population residing in central and western regions of Nepal.Methods: This retrospective cross-sectional study was carried out by reviewing the records of vitamin D tests in two centers of Nepal- namely united reference laboratories at Pokhara and Chitwan Medical College at Chitwan. A total of 3320 individuals who were tested for clinical suspicion of vitamin D deficiency over a period of one year were included in the study. Results: Mean vitamin D level was 18.7 ng/mL. Majority of subjects tested for vitamin D were females (71.36 %) with female to male ratio of 2.49:1. Hypovitaminosis D (? 30 ng/mL) was found in 84.5% subjects and was moderate to severely deficit (<10 ng/mL) in 25.9% of subjects. Status of hypovitaminosis D was found to be less in ?50 years (79.9%) than the younger subjects (89.9% in ?18 years and 87.0% in 19-49 years age group). Vitamin D deficiency was found lower in hills districts (80.8% vs 89.7% in the plains), which was found to be more pronounced during winter through summer seasons as compared to fall season.Conclusions: Population residing in plain areas and summer, spring and winter season are found to have increased problem of Hypovitaminosis D. It is also found to be common among younger children and female of reproductive age group. We have also found out the increased problem of hypovitaminosis D among population residing in the plain areas than in the hills especially in the summer, spring and winter season.Keywords: Geographic variation; hypovitaminosis D; Nepal

Aim. To determine serum 25(OH)D and plasma MMP-2 and MMP-9 levels in patients with primary open-angle glaucoma (POAG), pseudoexfoliation glaucoma (PEG), and pseudoexfoliation syndrome (PES) - to assess potential associations between vitamin D status and these diseases. Methods. We included 238 patients (105 males and 133 females) aged from 55 to 75 years. One hundred twenty two patients had PEG, 46 patients had POAG, 32 had PES. 38 subjects were healthy, and were considered as the control group. Cases with clinically significant systemic diseases and concomiatant eye diseases were excluded, if there was a confirmed pathogenic impact of vitamin D and MMP. The serum 25(OH)D level was investigated by immunochemiluminescence method, plasma MMP-2 and MMP-9 levels - by ELISA. Results. Serum 25(OH)D level was between 4.6 and 82.25 nM/l (mean 41.7 nM/l), so most participants showed vitamin D deficiency. It was shown that mean serum 25(OH)D level in patients with PEG, POAG and PES was similar (39.3 ± 1.2, 38.8 ± 2.1 and 40.51 ± 2.4 nM/l, p > 0.05), but it was lower than that in the control group (52.7 ± 2.1 nM/l, p < 0.01). Plasma MMP-2 concentration was the same in all study groups. Plasma MMP-9 level was higher in POAG and PES patients (48.23 ± 3.26 and 54.01 ± 3.57 ng/ml) than in the control group (32.60 ± 2.34 ng/ml, p < 0.001) and PEG patients (40.86 ± 3.60 ng/ml, p < 0.05). We found positive correlations between MMP-2 and MMP-9 levels in patients with PEG (r = 0.48, p = 0.001) and patients with POAG (r = 0.43, p = 0.003). The correlation analysis showed also a negative relation between 25(OH)D and MMP-9 (r = -0.32, p = 0.02), MMP-2 (r = -0.33, p = 0.02) in patients with POAG. Summary. Study results confirmed a potential role of vitamin D in apoptosis regulation and tissue remodeling in patients with POAG and PES. Hence, vitamin D deficiency can be considered as a risk factor for glaucoma development.
