有关文献提及“学生HBSAg长期携带者，对生长发育有影响，发育处于中下等水平”[1]，但未见报道具体的统计数据。HBsAg检查阳性与阴性学生生长发育水平是否有差异？我们选择生长发育水平已趋于相对稳定的大、中专、技工学校学生进行调查。1对象与方法抽查九所大、中专、技校学
The literature mentions that “long-term carriers of HBSAg in students have an impact on growth and development and have moderate to low developmental levels” [1], but no specific statistics have been reported. Are there any differences between HBsAg positive and negative students’ growth and development? We choose the level of growth and development has become relatively stable in large, secondary, technical school students to investigate. 1 object and method checks nine large, technical secondary school, technical school
