不同夜间喂养终止时间对婴幼儿生长发育的影响

Effect of different night feeding termination time on the growth and development of infants and young children

目的探讨不同夜间喂养终止时间对婴幼儿生长发育的影响。方法选取2017年1月至2018年1月于余姚市妇幼保健院足月出生并纳入儿童保健系统管理的418例婴幼儿为研究对象,根据在6月龄后是否继续夜间喂养分为继续组(n=270)和终止组(n=148),比较两组婴幼儿30月龄时身高、体重、超重肥胖发生率以及龋齿患病率。结果两组婴幼儿30月龄时,继续组身高显著低于终止组,继续组超重以及超重肥胖发生率显著高于终止组,差异均具有统计学意义(t/χ^(2)值分别为6.283、5.279、8.173,均P<0.05);两组婴幼儿体重以及肥胖发生率比较差异无统计学意义(均P>0.05);418例研究对象中,53例出现龋齿,龋齿患病率为12.68%,继续组的龋齿患病率以及龋齿数均显著高于终止组,差异具有统计学意义(t/χ^(2)值分别为7.392、5.283,均P<0.05)。结论6月龄后继续夜间喂养会严重影响婴幼儿的生长发育,显著增加超重肥胖率以及龋齿的患病风险。

Objective To explore the effects of different night feeding termination time on the growth and development of infants and young children.Methods A total of 418 infants and young children,who born at full term in Yuyao Maternal and Child Health Hospital and were included in the management system of child health care,were selected as the research objects.According to whether nocturnal feeding was continued after 6 months of age,all of them were divided into the continuation group(n=270)and the termination group(n=148).The height,weight,the incidence of overweight and obesity and the prevalence of dental caries at 30 months of age were compared between the two groups.Results When the young children at the age of 30 months,the height of the continuation group was significantly lower than that of the termination group,and the incidence of overweight and overweight+obesity in the continuation group were significantly higher than those of the termination group,the differences were statistically significant(t/χ^(2) values were 6.283,5.279 and 8.173,respectively,all P<0.05).But there was no significant difference in the weight and obesity incidence between the two groups(all P>0.05).Among 418 cases of the research object,53 cases with dental caries,and the prevalence was 12.68%.The prevalence rate and number of dental caries of the continuation group were significantly higher than those of the termination group,the differences were statistically significant(t/χ^(2) values were 7.392 and 5.283,respectively,both P<0.05).Conclusion Continuing night feeding after 6 months of age will seriously affect the growth and development of infants and young children,leading to an increased risk of dental caries,overweight and obesity.
