INTRODUCTION: Obesity represents the major risk factor for development of insulin resistance during childhood and adolescents. In obesity, adipose tissue release free fatty acids, various hormones, and cytokines, resulting in insulin resistance. This study aimed to establish the correlation between vitamin D deficiency and the incidence of insulin resistance in obese children. DESIGN AND METHOD: This analytical cross-sectional study was arranged from December 2019 - February 2020 included 96 students aged 11 - 17 years old from junior and senior high school who met the criteria for obesity in Makassar. The study subjects were parted into two groups, obese children with vitamin D deficiency (levels of 25-hydroxyvitamin D ≤ 20 ng/ml) and obese children without vitamin D deficiency group (levels of 25-hydroxyvitamin D > 20 ng/ml). Data were analyzed using univariate and bivariate analysis. RESULTS: The frequency of insulin resistance in obese children with vitamin D deficiency was 28 (54.9%), while obese children without vitamin D deficiency was 10 (22.2%). Based on statistical analysis, the frequency of the occurrence of insulin resistance in vitamin D deficiency obese children was higher than in obese children without vitamin D deficiency with OR = 4.261 (95% CI 1.744 – 10.411), p = 0.001. CONCLUSION: The risk of insulin resistance in obese children with vitamin D deficiency is 4.261 times higher than obese children without vitamin D deficiency.

Nutritional Status Of Children

Objective. To evaluate the nutritional status of children from 12 to 36 months of age in Kimdong, a rural district in Hungyen Province, Northern Vietnam, in 2017. Subjects and Methods. A cross-sectional study was carried out on 327 children aged 12-36 months. The data collected included anthropometric measurement, serum hemoglobin (Hb), and vitamin D concentration. Blood analysis was done at the Center Laboratory of Hungyen Obstetrics and Pediatrics Hospital. Underweight, stunted, and wasted children were classified based on z-scores cut-off less than -2 SD of weight for age (WAZ), height for age (HAZ), and weight for height (WHZ), respectively. Overweight and obese children were defined if WHZ was more than + 2SD. Anemic child was applied when Hb concentration was less than 110 g/L while vitamin D deficiency was termed for level less than 20 ng/L. Results. The prevalence of underweight, stunted, wasted, and overweight/obese children was 7.6%, 23.5%, 6.7%, and 1.2%, respectively. The prevalence of anemia and vitamin D deficiency was 33.3% and 47.7%, respectively. Malnutrition, anemia, and vitamin D deficiency were not statistically different by sex. Malnutrition and vitamin D deficiency were not statistically different by age group but anemia by age groups was significantly different. Conclusions. Stunting is still prevalent in children aged 12-36 months in Kimdong. Moreover, anemia and vitamin D deficiency also affected children in this area. Some interventions should be conducted to improve the nutritional status of children in Kimdong district.

Abstract Background and objectives Both childhood obesity and vitamin D deficiency are common in the Middle East. This systematic review/meta-analysis aims to highlight the effect of vitamin D supplementation in deficient children suffering from obesity. Methods Published clinical studies on vitamin D supplementation in obese children and adolescents with vitamin D deficiency were identified through a comprehensive MEDLINE/PubMed search (from July 1966 to November 2017). Outcomes intended after vitamin D supplementation were improvements in vitamin D status, BMI alterations and appetite changes. The inclusion criteria were children aged 2 to 18 years of both sexes in clinical trials that specified the oral and/or intramuscular dose of vitamin D supplementation. Results Ten studies were retrieved, but only six were relevant. First, supplemented obese children and adolescents were compared to non-obese controls; thereafter, supplemented obese children and adolescents were compared to matching obese peers given placebo. Pooled risks from the two studies that evaluated the number of obese and non-obese children and adolescents who improved upon vitamin D supplementation revealed that obesity poses a risk for not benefiting from the vitamin D supplementation regardless of the dose and the duration of supplementation. Pooled results from the six retrieved studies that compared supplemented obese children and adolescents to matching non-obese or obese peers given placebo revealed significantly lower vitamin D levels in obese participants than in non-obese peers. Conclusion Vitamin D levels are significantly lower in obese children and adolescents with obesity, posing a risk for not benefiting from vitamin D supplementation regardless of the dose and duration of supplementation. Our results suggest that only with simultaneous weight adjustment strategies, vitamin D sufficiency would be achieved more effectively. Vitamin D supplementation in deficient children suffering from obesity.

Objectives: Obesity has been mentioned as a high risk factor for Vitamin D deficiency (VDD) requiring supplementation in Indian children. Material and Methods: Forty obese and age-matched non-obese subjects (age 5–18 years) were assessed for lifestyle parameters, metabolic profile, and serum 25-hydroxyvitamin D (25OHD). VDD was defined as serum 25OHD < 12 ng/mL. Results: Mean 25OHD was comparable among obese and controls (15.0 ± 9.95 and 15.1 ± 4.79 ng/mL; P = 0.97) with VDD seen in 82% of cases and 85% of controls. Pubertal cases had lower 25OHD values than prepubertal obese cases (10.78 ± 4.69 and 17.2 ± 11 ng/mL; P = 0.06). Mean duration of physical activity (<2 h/week) and screen time (>2 h/day) was similar across prepubertal and pubertal groups and between obese and controls. Obesity was not associated with risk for VDD among cases and controls (odds ratio 0.83, 95% C.I. 0.25–2.7, P = 0.76). Conclusion: Obese pubertal subjects were more at risk for VDD than prepubertal subjects. Routine Vitamin D supplementation to obese Indian children may be considered during adolescence.

Vitamin D Levels

Background: Vitamin D deficiency is common among children and adolescents and can be affected by several factors such as puberty and obesity. Objective: The aim of this study was to evaluate vitamin D status in children and adolescents and to analyse the influence of puberty and obesity on its level. Method: A cross-sectional study was carried-out, in which clinical and biochemical data were gathered from 384 healthy children and adolescents between May 2019 to May 2020. Results: 220 females and 164 males were enrolled (aged 7-16 years; mean ± SD: 11 ± 2.5). Vitamin D deficiency was found in 49% of the total cases and was significantly more prevalent in females than males (33.1% in female; 15.9% in male, P < .001). Mean vitamin D level was lower in obese children compared with non-obese ( P < .001). Non-obese group had significantly higher levels of vitamin D in Tanner stage IV of puberty than obese individuals (20.1 ± 17.0 vs 5.4 ± 2.0) ( P = .03). Vitamin D levels were significantly lower in females than males only in Tanner stage II (12.3 ± 9.0 vs 19.6 ± 16.6) ( P = .005). The lowest level of Vitamin D was in Tanner stage Ⅳ-Ⅴ in boys and in Tanner stage Ⅱ-Ⅲ in girls ( P < .001). Conclusion: Puberty is an additional risk factor for vitamin D deficiency especially in girls and obese children. This increased risk, together with the fact that most important time for building a proper skeleton is during childhood and adolescent, makes it essential to monitor vitamin D in these age groups.
