Introduction: Body weight gain in children and teenagers is one of the major challenges that cause undesirable health outcomes. Simultaneously with the prevalence of overweight and obesity, children and adolescents are diagnosed with 25-hydroxyvitamin D (25(OH)D) deficiency in different sides of the world. The present study aimed to assess 25(OH)D status among Iranian volunteers aged 1-16 years and find the correlation between 25(OH)D status and body mass index (BMI) subjects.    Material and Methods: The total volunteers included 807 Iranian children aged 1 to 16 referred to the general and endocrinology clinics in Babol city, Mazandaran Province. A trained physician determined anthropometric characteristics. Serum levels of calcium (Ca), phosphate (P), creatinine (Cr), urea, thyroxine (T4), thyroid-stimulating hormone (TSH), and 25(OH)D were assessed in all children.      Results: 25.27% of the children were 25(OH)D deficient, and 59.1% were insufficient. There was no significant difference in serum 25(OH)D level between girls and boys (P=0.13). A significant negative correlation was found in serum 25(OH)D level with weight (P=0.000, r=-0.12), BMI (P=0.000, r=-0.13), and age (P=0.000, r=-0.13). Conclusion: These data displayed that 25(OH)D insufficiency is highly prevalent among children in the north of Iran. Serum 25(OH)D levels are affected by age and BMI value. Improving vitamin D deficiency helps to maintain the health of children and adolescents during this critical period.

Introduction: Osteoporosis is the most common metabolic bone disease. Vitamin D deficiency, often associated with osteoporosis and other bone tissue disorders, is spread worldwide. Among other factors, obesity seems to be a major cause of the growing hypovitaminosis D. Aim: The aim of the study was to assess the correlation between body mass index (BMI) and vitamin D concentrations in postmenopausal women diagnosed with osteoporosis. Materials and methods: Sixty nine women with postmenopausal osteoporosis were included in study. Dual- energy X-ray absorptiometry and vitamin D measures were performed in all patients. Three groups, BMI- dependent, were distinguished: normal weight, overweight and obesity group. Results: The vitamin D deficiency was found in all women with postmenopausal osteoporosis. There was no correlation between BMI and vitamin D level. Conclusions: Vitamin D deficiency is frequent in population of patients diagnosed with postmenopausal osteoporosis, regardless of their BMI.

Aim: To determine the role of vitamin D in the management of COVID-19 patients regarding morbidity and mortality. Study Design: Prospective/Observational Place and Duration: Departments of Medicine & Pulmonology, Allama Iqbal Memorial Teaching Hospital, Sialkot and Department of Medicine, Sughra Shafi Medical Complex Narowal from 1st November 2020 to 30th April 2020. Methodology: One hundred and sixty patients of both genders diagnosed to have COVID-19, were enrolled. Patient’s ages were ranging from 17 to 70 years. The detailed demographics such as age, sex, and body mass index were recorded. 5 ml blood samples were taken from all the patients to check their vitamin D levels. Severe Vitamin D deficiency was defined as 25(OH)D <25 nmol/L (10 ng/dl). Association between mortality and morbidity was examined. Results: Ninety (56.25%) were males while 70 (43.75%) were females with mean age 40.15±17.37 years. Mean body mass index of patients was 24.16±7.26 kg/m2. Severe vitamin D deficiency was observed in 80 (50%) patients. Mortality found in 30 (18.75%) patients. Frequency of morbidity was among 66 (41.25%) patients. Patients with severe vitamin D deficiency had high rate of mortality 20 (25%) and morbidity 50 (62.5%) as compared to patients with no vitamin D deficiency had 10 (8%) mortality and 16 (20%) morbidity. A significant association was observed between severe vitamin D deficiency regarding morbidity and mortality among patients with covid-19 disease with p-value <0.05. Conclusion: The vitamin-D has strongest relationship among patients with covid-19 disease to reduce mortality and morbidity. Keywords: Morbidity, COVID-19, Vitamin D, Mortality

Objective. To evaluate vitamin D deficiency and body composition of women submitted to bariatric surgery and relate their body mass index variation after surgery to 25(OH)D concentrations. Method. A cross-sectional and controlled study was performed including 49 obese adult volunteer women, submitted to Roux-en-Y gastric bypass (RYGB group). Collected Data. Body mass index (BMI), self-declared ethnicity, economic condition, physical activity level, serum concentrations of 25-hydroxycholecalciferol (25(OH)D; radioimmunoassay), parathormone, and body composition by dual-energy X-ray absorptiometry (Hologic DXA-QDR-1000) were collected. Results. 25(OH)D deficiency was found in 27 (55.1%) and 8 (21.1%) in the RYGB and control groups (p=0.002). Secondary hyperparathyroidism was more frequent in the RYGB group compared to the control group (15 (30.6%) versus 1 (2.6%); p=0.001). There was no relation of the studied variables and body composition with 25(OH)D deficiency. 25(OH)D concentrations were correlated (r=−0.531; p<0.001) with BMI reduction, regardless of vitamin D supplementation. Conclusion. Women submitted to bariatric surgery (RYGB) around three years ago had higher BMI and vitamin D deficiency, along with hyperparathyroidism, compared to the control group. There was no association between variables related to body composition and 25(OH)D concentrations. On the other hand, vitamin concentrations correlated negatively to BMI variation after undergoing surgery.
