学龄前肥胖儿童血清维生素A、E水平分析

AEAEAAEAnalysis on levels of serum vitamin A and E in obese pre-school children

摘要

摘要: 目的：了解学龄前肥胖儿童维生素A、E营养状况，分析其与肥胖发生的相关性。方法：选择超重及肥胖儿童50例、体重正常儿童50例，分别设为超重组、肥胖组和对照组。采集静脉血，测定血清维生素A、E水平。结果：三组儿童血清维生素A、E水平存在显著差异（P<0.05）。超重组和肥胖组儿童血清维生素A水平明显低于对照组（P<0.05），肥胖组儿童维生素E水平较正常组显著降低（P<0.05）。三组儿童维生素E不足发生率存在显著差别，趋势为肥胖组>超重组>对照组（P<0.05）。此外，血清维生素A、E水平与BMI呈负相关（r= -0.395，P=0.000；r= - 0.374，P=0.000）。结论：维生素A、E水平在超重肥胖儿童中显著降低，这可能与学龄前儿童肥胖的发生具有一定相关性。

Abstract: Objective：To investigate the nutritional state of vitamin A and E in obese children, and to analysis the relationship between vitamin A and E and obesity. Methods：Fifty overweight or obese children and Fifty healthy children were divided into overweight group, obese group and control group. The venous blood was collected to detect the content of vitamin A and E. Results: There was statistical difference in serum level of vitamin A and E among three groups (P<0.05). Serum levels of vitamin A in overweight and obesity children were significantly lower than that in the controls (P<0.05). The level of vitamin E in obese group was significantly decreased compared with control group (P<0.05). The insufficiency rate of vitamin E was obviously different and showed the trend of obese group>overweight group> control group decreased. Serum levels of vitamin A and E were inversely associated with BMI (r= -0.395，P=0.000；r= - 0.374，P=0.000). Conclusions: Serum levels of vitamin A and E in overweight and obese children were significantly decreased，which maybe associated with the occurrence of obesity in pre-school children
