【摘要】 目的研究厦门市足月小于胎龄儿(small for gestational age,SGA)生后一年生长发育情况,为今后对小于胎龄儿进行有效干预提供依据。方法选取2016年6月-2017年6月出生、在厦门大学附属妇女儿童医院接受保健服务的足月小于胎龄儿,共163例,同期的适于胎龄儿(appropriate gestational age,AGA) 387例作为对照组,随访其1月龄、3月龄(±7d)、6月龄(±7d)、8月龄(±7d)、12月龄(±7d)的身长和体重。采用Z评分法评定儿童的生长发育状况,若△Z积分≥0. 67定义为出现追赶生长。结果①身长追赶率1月龄60. 42%,3月龄64. 74%,6月龄57. 69%,8月龄62. 75%,12月龄60. 69%,可见3个月内是身高追赶生长的关键时期。体重追赶率1月龄70. 07%,3月龄72. 78%,6月龄71. 70%,8月龄67. 52%,12月龄65. 33%,相比身长追赶而言,体重追赶主要在6个月内,而且体重追赶率明显大于身高追赶率。②SGA组男童、女童的体重和身高在1、3、6、8及12月龄均低于对照组,差异具有统计学意义(P <0. 001)。结论足月SGA生后1年内出现不同程度的追赶生长,且生后6个月内是追赶生长的关键期。更多还原

【Abstract】 Objective To study the growth of the full-term small for gestational age infant(SGA),to provide the basis for the effective intervention and education of the premature infant(PI). Methods The full-term SGA group included 163 singleton alive fullterm SGA delivered in our hospital during June 2016 to June 2017,387 cases were randomly selected by birth weight of 10% to 90%of its spaces appropriate for AGA and taken as a control group. The body length and body weight of 1 month,3 months(± 7 days),6 months(± 7 days),8 months(± 7 days) and 12 months(± 7 days) were followed up. The growth and development of Children were evaluated by Z score. △Z score ≥ 0. 67 was defined as catch-up growth. Results ①The catch-up rate of body length at 1 month,3 months,6 months,8 months and 12 months was 60. 42%,64. 74%,57. 69%,62. 75% and 60. 69%,respectively. It can be seen that 3 month is the key period for height to catch up with growth. The catch-up rate of body weight at 1 month,3 month,6 month,6 month,8 month and 12 month was 70. 07%,72. 78%,71. 70%,67. 52% and 65. 33%,respectively. Compared with the catch-up rate of body length,the catch-up rate of body weight was mainly within 6 month,and the catch-up rate of body weight was significantly higher than that of height. ②The body weight and length of boys and girls in SGA group were lower than those in control group at the ages of 1 month,3 months,6 months,8 months and 12 months. The difference was statistically significant(P < 0. 001). Conclusion The full-term small for gestational age infants physically chase up obviously within the first year. They keep a higher chasing up speed especially in 6 months.更多还原
