【摘要】 应用一种多元回归方法制定儿童少年体重正常值范围,结果与单指标体重正常值范围很接近。通过对重庆市1050名中小学生身高、胸围和体重实测值分布的分析,讨论了单指标正常值范围在当前实用中评价儿室少年形态发育中的作用意义。更多还原

【Abstract】 A multiple regression equation relating height and chest circumference to body -weight is prop-ouded. If values for the heights and chest circumferences of a group are put into this equation, the 95% normal value for body weight calculated from the equation is found to be very close to the known 95% normal range for the body weight for that age. The validity of using single indicators to assess physical development during childhood and adolescence is discussed. Estabishing normal range is put forward.更多还原
