25-hydroxy vitamin D, adiponectin levels and cardiometabolic risk factors in a sample of obese children

Abstract

BACKGROUND: Association between vitamin D, adiponectin and obesity is a matter of debate, as they play important role in linking obesity with different cardio metabolic risk factors. AIM: Evaluation of association between metabolic risk factors with both adiponectin and 25-Hydroxy vitamin D [25(OH) D] levels and that between adiponectin and [25(OH) D] among obese Egyptian children. SUBJECTS AND METHODS: This case-control cross sectional study consisted of 65 obese and 30 healthy children, aged 8-11 years. 25(OH) D, serum adiponectin, total cholesterol, triglycerides, high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol were measured. RESULTS: The mean 25(OH)D and adiponectin levels in the obese were lower than that in control group (<0.000). 25(OH)D were inversely correlated with body mass index, triglyceride, total cholesterol and LDL-cholesterol. While adiponectin level were inversely correlated with systolic and diastolic blood pressure, and positively correlated with high-density lipoprotein-cholesterol. However, there is no relation between 25(OH) D and adiponectin levels among obese children and total sample. CONCLUSION: Inspite of strong association between vitamin D and adiponectin levels with metabolic risk factors and obesity, there is no relation between 25(OH)D and adiponectin levels. In obese children, There are significant negative correlations between 25(OH)D with lipid profile, and between adiponectin levels with blood pressure.
