چکیده
Background and Aim: Some studies have examined the association between micronutrients deficiency and obesity in children, but data in this regard are conflicting. This study was done to investigate the association between serum levels of vitamin D, retinol and zinc with overweight in a large sample size of Iranian toddlers aged 15-23 months. Methods: A total of 4393 children aged 15- 23 months who had Iranian birth certificate and attended primary health care system, were included in this cross-sectional study. Weight and height were measured by experts based on standard protocols. Body mass index (BMI) was calculated. Overweight was defined as BMI-z-score of one SD or above based on WHO criteria. Serum levels of vitamin D, retinol and zinc was examined based on standard methods Results: Mean age of study participants was 19.2 ± 8.4 months. After controlling for potential confounders, children in the highest quartile of serum vitamin D levels had lower odds of overweight compared with those in the lowest quartile (OR: 0.79, 95%CI: 0.63-0.99). Furthermore, a marginally significant inverse association was found between serum levels of vitamin D and overweight among urban toddlers (OR: 0.75, 95%CI: 0.56-1.00). Such relationship was not seen for rural children. No other significant association was seen between serum levels of retinol and zinc and overweight either before or after controlling for covariates.Conclusion: In conclusion, we found a significant inverse association between serum levels of vitamin D and overweight among toddlers. Further studies, particularly of prospective nature, are required to confirm our findingsکلیدواژه ها
