摘要:
分析宁夏回族自治区中小学生贫血与营养状况之间的关联性,为少数民族地区中小学生营养改善计划提供依据.方法 选取2014年宁夏回族自治区学生体质和健康调研的7,9,12和14岁年龄组3 747名回汉族中小学生,采用世界卫生组织(WHO)和联合国儿童基金会制定的贫血诊断标准,根据中国学龄儿童超重肥胖人体质量指数(BMI)分类标准和2014年颁布的国家卫生标准《学龄儿童青少年营养不良筛查标准》(WS/T 456-2014)评定营养状况.结果 回、汉族学生总体贫血检出率为4.7%,汉族学生贫血检出率(2.6%)高于回族学生(2.1%),农村学生(5.5%)高于城市学生(3.9%),女生(6.1%)高于男生(3.4%)(x2=4.17,P<0.05).在贫血学生中,回、汉族学生轻度贫血检出率分别占3.2%,3.5%;中度贫血检出率分别为1.3%,1.2%;汉族学生无重度贫血,回族学生重度贫血检出率为0.2%(x2=7.77,P>0.05).不同经济片区中,中等片区回族学生贫血率最高(4.1%),其次为好片区汉族学生(2.1%),差片区回族学生未检出贫血者.汉族学生消瘦、正常、超重和肥胖检出率分别为5.5%,42.1%,5.7%,3.6%,回族学生分别为4.4%,32.0%,4.3%,2.4%,不同民族间营养状况构成差异无统计学意义(x2=1.27,P>0.05).各个年龄组中,12岁学生贫血检出率最高,为1.7%,其次为14岁学生.结论 回、汉族学生贫血检出率不同,应重视农村学生的贫血防治知识教育,尤其要加强青春期少女的健康教育;对于经济发展好的片区,进行贫血知识教育,提倡合理膳食;加强学生贫血筛查工作.
