夜间喂养终止时间对婴幼儿生长发育的影响

Effects of end time of night feeding on the growth and development of infants/toddlers

目的探讨夜间喂养终止时间对儿童30月龄时身高、体重、营养状况及龋齿患病率的影响。方法选择2014年1月至2015年9月出生并在儿童保健门诊按要求完成健康体检的416例儿童,在其30月龄体检时采用综合儿童保健记录并辅以自制调查问卷的方式,将6月龄后继续夜间喂养者作为研究组(n=269),6月龄终止夜间喂养者作为对照组(n=147)。比较两组儿童在30月龄时身高、体重、超重/肥胖发生率及龋齿患病率的差异。结果研究组儿童30月龄时平均身高低于对照组(92.4±3.0 cm vs 93.3±2.8 cm,P<0.05),且具有更高的超重/肥胖发生率(23.8%vs 12.2%,P<0.05)和更高的龋齿患病率(14.9%vs 7.5%,P<0.05)。结论 6月龄后继续夜间喂养影响婴幼儿生长发育、造成营养过剩以及增加龋齿患病率。

Objective To investigate the effects of end time of night feeding on body height,body weight,nutritional status,and prevalence rate of dental caries in children at the age of 30 months.Methods A total of 416 children who were born from January 2014 to September 2015 and had completed a physical examination as required were enrolled.During the physical examination performed at the age of 30 months,the comprehensive child care record and a self-made questionnaire were used.The children who continued to receive night feeding after the age of 6 months were enrolled as study group（n=269）,and those for whom night feeding was ended at the age of 6 months were enrolled as control group（n=147）.The two groups were compared in terms of body height,body weight,incidence rate of overweight/obesity,and prevalence rate of dental caries at the age of 30 months.Results Compared with the control group,the study group had a significantly lower body height（92.4±3.0 cm vs 93.3±2.8 cm;P〈0.05）,a significantly higher incidence rate of overweight/obesity（23.8%vs 12.2%;P〈0.05）,and a significantly higher prevalence rate of dental caries（14.9%vs 7.5%;P〈0.05）at the age of 30 months.Conclusions Night feeding continued after the age of 6months can affect the growth and development of infants/toddlers,cause overnutrition,and increase the prevalence rate of dental caries.
