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.
Abstract:
Objective To understand the correlation between the detection rate of anemia among Chinese teenagers and the physical factors,and to provide a reference for preventing anemia in the physical perspective.Methods Totally 71 687 students aged 7,9,12,14 year-old from the monitoring sites of schools of Chinese Students Constitution and Health Research were recruited by stratified random sampling method,and their hemoglobin indexes were examined.The correlation between detection rate of anemia and physical factors was analyzed by logistic regression.Results The detection rate of anemia was 13.0% in 2014,which was lower than that of 2010 by 1.2 points.Age,gender,district of living,results of 50 meter race and endurance running were influencing factors of the detection rate of anemia.Furthermore,results of 50 meter race and endurance running were positively correlated with the detectionrate of anemia.Conclusion The girls aged 7 to 14 in rural areas should be taken as focus of the prevention and control of anemia,and more attention should be paid to the the physical exercies to improve the prevalence of anemia among children and adolescents.
