北京市413名7～11岁儿童血清抗氧化维生素水平调查

Survey on the Serum Anti-oxidation Vitamin Levels of 413 Children Aged 7-11 in Beijing

目的 了解不同营养状态儿童血清抗氧化维生素水平及其影响因素。方法 对北京市 413名 7～ 11岁儿童 (其中肥胖儿童 2 2 3名 ,超重儿童 98名和体重正常儿童 92名 )进行了问卷调查及血清脂溶性维生素 (α -生育酚、β-胡萝卜素及维生素A)水平测定。结果 随实测体重超过身高标准体重幅度的增加血清维生素A上升、α -生育酚下降 ,各组间比 ,差异无显著性 (P >0 0 5 ) ;β -胡萝卜素下降 ,各组间比 ,差异有显著性 (P <0 0 5 )。肥胖儿童维生素E摄入低于体重正常儿童 ,但差异无显著性 (P >0 0 5 )。结论 肥胖儿童血清脂溶性抗氧化维生素水平低于体重正常儿童。

Objective To identify the levels of serum anti-oxidation vitamins in children under different nutrition states and influencing factors. Methods A questionnaire survey was administed and the serum levels of fat-soluble vitamins(α-tocopherol,β-cortene and vitamin A)in 413 children aged 7-11 in Beijing were tested,including 223 obese,98 overweight and 92 normal-weight children. Results The level of vitamin A increased along with the increasing degree that the measured weight excessed the Weight for Height methods,while that of α-tocopherol decreased without statistical significance( P >0.05).Only the decreasing of β-cortene was statistically significant( P <0.05).Intaking of vitamin E in obese children was lower than that in normal-weight children without significant difference( P >0.05). Conclusions The results indicate that the level of serum fat-soluble anti-oxidation vitamins of obese children is lower than that of normal-weight children.
