The aim of this article was to focus on vitamin A level in obese children compared with normal controls and to determine the relation between levels of retinol with lipid profile and an inflammation marker.
Participants and methods
Thirty obese and 30 normal weight children, who served as controls, were included in our study. All were subjected to clinical and anthropometric evaluation. Laboratory assessment of high-sensitivity C-reactive protein and lipid profile was performed. Vitamin A levels were quantified.
Results related to lipid profiles and vitamin A levels revealed that low-density lipoprotein, cholesterol, and triglycerides were highly significantly higher in cases than in controls (P<0.001), whereas vitamin A was statistically significantly lower in cases (P=0.000). Correlations between plasma vitamin A and the studied variables showed negative correlation with weight (kg), low-density lipoprotein, and cholesterol, whereas there was a positive correlation between plasma vitamin A and triglyceride level.
Our results revealed that obese children tend to have hyperlipidemia and vitamin A insufficiency compared with their nonobese counterparts. We recommend nutritional education about vitamin A and control of body weight through various means as remedial measures.
