摘要:
了解湖北省中部贫困农村地区中小学生贫血现况及饮食行为,为更好地促进学校健康教育、提高学生自我保健意识提供依据.方法 采用分层整群抽样的方法,从鄂东北、鄂中、鄂西北、鄂西南贫困农村地区抽取8个县(市),共32所中小学5 942名中小学生进行血红蛋白测量;同时从研究对象中抽取所有小学四、五年级和初中一、二年级学生共计2 569名进行问卷调查.结果 中小学生的贫血检出率分别为14.05%,14.86%,差异无统计学意义(x2=0.680,P>0.05).男、女生贫血检出率分别为12.55%,16.72%,差异有统计学意义(x2=20.666,P<0.01).小学6~8岁组学生(15.24%,23.3%,17.72%)、初中16岁组学生(19.85%)的贫血检出率较高.贫困地区中小学生每天吃早餐的比例为74.42%,早餐都能吃饱的比例为47.29%.新鲜水果、畜禽肉类、鱼虾及贝类、蛋类、奶及其制品、豆制品的年均食用频次均不高(M值分别为365.0,365.0,104.0,365.0,365.0,365.0).小学生、初中生回答“怎样预防缺铁性贫血”的正确率分别为24.09%,31.61%,差异有统计学意义(x2=18.080,P<0.01).结论 湖北省中部贫困地区中小学生贫血检出率偏高,需加强学校健康教育,有效预防高发年龄段学生贫血的发生.
