婴幼儿头发稀疏的因素分析

Analysis on the effect factors of infants with thin hair

目的:探讨婴幼儿头发稀疏的因素。方法:采取分组对照、纵向追踪、整体抽样调查的方法对237例被监测儿童的性别、孕期情况、有关疾病、矿物质进行分析,其中头发稀疏63例(头发稀疏组),头发浓密112例(对照组)。并按工作流程追访两组头发生长情况4年。结果:头发稀疏的产生机制与亲代幼年时是否同样存在头发稀疏存在明显关联(P<0.01);头发稀疏组与对照组矿物质检测结果比较,差异无统计学意义;3岁前头发稀疏组头发直径明显细于对照组,两组比较有统计学差异(P<0.01),4岁时头发稀疏组头发直径仍细于对照组,但差别无统计学意义。结论:婴幼儿期头发稀疏为出生后遗传信息表达的生理现象,合理的饮食结构有助于头发的生长发育,3～4岁时头发便会逐渐生长正常,存在明显的追赶过程。

Objective：To explore the effect factors of infants with thin hair.Methods：Grouping control,vertical tracking and overall sampling survey method were used to analyze the gender,pregnancy status,related diseases and minerals among 237 children,the children were divided into thin hair group（63 children） and thick hair group（112 children）.The growths of hair in the two groups were followed up for 4 years according to working process.Results：The mechanism of thin hair was related to thin hair or not of their parents during childhood（P〈0.01）;there was no significant difference in minerals contents between thin hair group and control group;for the children under 3 years,the diameter of hair in thin hair group was significantly thinner than that in control group,there was significant difference（P〈0.01）;for the children under 4 years,the diameter of hair in thin hair group was also thinner than that in control group,but there was no significant difference.Conclusion：Thin hair during childhood is a physiological phenomenon of genetic information expression after birth,reasonable dietary structure is helpful to growth and development of hair,hair of the children aged 34 years old grow to normal gradually,showing an obvious catch-up proc
