惠州市儿童胎龄及年龄与体质量分布曲线研究

Study on fetal age,age,and weight distribution curve of children in Huizhou

目的绘制出符合惠州当地胎儿和儿童生长发育情况的曲线图。方法通过收集惠州市各区县140 045名新生儿出生信息数据,以及641 711名1～6岁儿童体检数据,使用BCPE模型,利用R-3. 3. 3,gamlss软件包,绘制针对惠州市地区的新生儿胎龄体质量曲线图,以及1～6岁儿童年龄体质量曲线图。结果使用Q-Q图以及密度估计对拟合结果进行检验,最终拟合结果比较准确。结论通过曲线对比,发现全国新生儿胎龄体质量曲线图和WHO儿童年龄体质量曲线图并不完全适用与惠州市,惠州市新生儿体质量不足或体质量过重的情况相对较少,并且惠州市属于经济相对发达地区,对儿童幼年期间的培养更加细致,因此儿童体质量要高于WHO标准。

Objective To draw a curve which matches growth and development of local fetuses and children in Huizhou.Methods The birth data of 140 045 neonates born in districts(counties)of Huizhou City and the data of 641 711 children receiving physical examination were collected,BCPE model and R-3.3.3,gamlss software package were used to draw fetal age and weight curve of neonates,age and weight curve of children aged 1-6 years old in Huizhou City.Results Q-Q diagram and density estimation were used to test the fitting results,and the final fitting results were accurate.Conclusion Curve comparison shows that national neonatal fetal and weight curve and WHO children age and weight curve are not fully applicable to Huizhou City.The numbers of underweight or overweight neonates are small.Huizhou City is economically developed,so the cultivation of children during their childhood is more detailed,children's average weight is heavier than WHO standard.
