Objective: 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: 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.
Conclusion: 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.
