【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29例及肥胖儿童21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 3组儿童血清维生素A、E水平比较差异有统计学意义(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水平较对照组明显降低(P <0.05),肥胖组维生素E不足率明显高于对照组(P<0.05);血清维生素A、E水平均与BMI呈负相关(r=-0.395,P<0.05;r=-0.374,P<0.05)。结论 维生素A、E水平在超重及肥胖儿童中显著降低,这可能与学龄前儿童肥胖的发生相关。更多还原

【Abstract】 Objective To investigate the nutritional state of vitamin A and E in obese pre-school children and to analyze the relationship between vitamin A and E and obesity.Methods A total of 50 overweight or obese children were divided into overweight group(n=29) and obesity group(n=21),and 50 healthy children were divided into control group.The venous blood was collected to detect the content of vitamin A and E.Results There was statistical difference in serum levels of vitamin A and E among the three groups(P <0.05).Serum levels of vitamin A in overweight and obesity groups were significantly lower than that in the controls(P <0.05).The level of vitamin E in obesity group was significantly decreased compared with control group(P <0.05).The vitamin E insufficiency rate in obesity group was significantly higher than that in control group(P <0.05).Serum levels of vitamin A and E were negatively correlated with BMI(r=-0.395,P <0.05;r=-0.374,P <0.05).Conclusions Serum levels of vitamin A and E in overweight and obese children are significantly decreased,which might be associated with obesity in pre-school children.更多还原
