以往一些学者曾探讨出生时身材大小(体重和身长)与出生以后生长速度之间的关系。他们都意识到应采用追踪调查的方法,但由于追踪调查对象失访过多而受到限制。作者采用了一种回归分析法,弥补了这一缺陷。这种方法与随访次数无关,系利用直线回归的斜率确定生长速度。作者以Pearson相关系数评价了3,995名儿童出生时体重、身长与婴幼儿期和儿童期生长速度之间的相互关系。
In the past, some scholars have discussed the relationship between birth size (weight and length) and the growth rate after birth. They all realized that the method of follow-up should be used, but they were limited by the number of follow-ups lost to follow-up. The author uses a regression analysis to make up for this shortcoming. This method has nothing to do with the number of follow-up, the use of linear regression slope to determine the growth rate. The authors evaluated Pearson’s correlation coefficient between 3,995 birth weight, length and infancy and childhood growth rates.
