| 摘 要： | 了解2014年中国青少年贫血检出率与体能因素的相关性,为预防贫血提供体能方面的依据.方法 采用分层随机整群抽样的方法,在全国学生体质与健康调研点校抽取7,9,12,14岁学生共71 687名,测定对象血红蛋白含量指标,计算贫血检出率,采用Logistic回归分析贫血检出率与体能因素的相关性.结果 2014年青少年贫血率为13.0%(男生为11.9%,女生为13.8%),比2010年下降1.2百分点.多因素Logistic回归分析显示,青少年年龄、性别、地区、50 m跑、耐力跑成绩是贫血检出率的影响因素(p值均<0.05),其中50 m跑、耐力跑成绩与贫血检出率呈正相关.结论 应重点防治乡村、女生、7岁和14岁青少年贫血的发生,重视体能项目对改善儿童青少年贫血的作用.
