| 目的 探讨体重指数(BMI)与儿童青少年体能指数(PFI)之间的关联.方法 以安徽省参加2010年全国学生体质健康调查的7～18岁汉族学生共8941人为研究对象.按性别、年龄分层后,将研究对象依据BMI百分位数分为5组:很低(BMI＜P5)、较低(P5≤BMI＜P15)、正常(P15≤BMI＜ P85)、较高(P85≤BMI＜P95)、很高(BMI≥P95).对各体能测试成绩进行标准化,将其Z分相加算出PFI.用方差分析比较不同BMI组PFI的差异.用线性回归模型分析不同性别不同学龄段学生BMI与PFI的关联.结果 8941名学生中BMI很低、较低、正常、较高、很高组的PF1分别为-1.77、-0.91、0.32、-0.17、-0.54,呈倒“U”形分布；BMI正常组的PFI显著高于其他各组(P值均＜0.05).回归分析显示PFI与BMI呈正相关,与BMI2呈负相关,表明PFI是BMI的二次函数,随着BMI的增高PFI呈现先上升后下降的抛物线变化趋势.结论 BMI与儿童青少年PFI呈现抛物线变化趋势. |

| Objective To explore the relationship between body mass index (BMI) and physical fitness index (PFI) among children and adolescents.Methods The study sample included 8941 students aged 7 to 18 years in Anhui who attended the Physical Fitness and Health Surveillance program of Chinese School Students,in 2010.Within each sex- and age-specific group,students were classified into five BMI categories which were:very low,BMI ＜5th percentile; low,BMI ≥5th but ＜15th percentiles; normal,BMI ≥15th but ＜85th percentiles; high,BMI ≥85th but ＜95th percentiles; and very high,BMI ≥95th percentiles.Z-scores based on urban-rural,sex- and age-specific means and standard deviations were calculated,and the sum of Z-scores for the fitness tests was used as a PFI.Differences in PFI between BMI categories were compared with ANOVA.Sex- and grade-specific regressions of PFI on BMI were done by using a linear model.Results For 8941 students,the PFIs on very low,low,normal,high and very high group were-1.77,-0.91,0.32,-0.17 and -0.54,respectively,and showed an inverted U shape.The normal BMI group students presented the highest PFI.Data from Linear regression analysis revealed that PFI was significantly positively correlated with BMI,while negatively associated with BMI square,which indicated that PFI was the quadratic function of BMI.When BMI was increasing,PFI showed a parabolic curvilinear.Conclusion Relationships between BMI and PFI were parabolic curvilinear among the children and adolescents aged 7 to 18 in Anhui province. |
