Abstract: Objective To know the height status and height genetic potential status among the preschool children in some cities. Method The multi-stage cluster sampling method was used to investigate the general situation of the preschool children,and their heights were measured. Results Totally 3 722 children (male:1 950,female:1 772) were investigated and analyzed.1)The average height of different genders of all ages were greater than the 50^th percentile of the corresponding standards.The height distribution of the southern city were poorer than that of the east and midwest urban.2)In the first survey,41.83% of the children′s growth potential performed poor. Conclusions The height situations of the preschool children in the survey areas are better than the reference standard.There are regional differences.The investigated children′s growth potential perform poor.

摘要： 目的 了解所调查城市学龄前儿童身高生长状况,了解学龄前儿童身高遗传潜能发挥状况。方法 采用多阶段分层整群抽样方法调查我国七城市学龄前儿童身高状况。通过体格测量和问卷进行调查。结果 共调查分析3 722例儿童(男:1 950例,女:1 772例)。 1)调查地区的学龄前儿童身高分布和身高增长高于参考标准平均水平,存在地域差异。2)41.83%的调查儿童遗传潜能发挥欠佳。结论 调查地区的学龄前儿童的身高状况整体较好,身高分布存在地域差异。调查地区的学龄前期儿童身高遗传潜能发挥情况较差。
