目的了解杨浦区人口发展趋势和变化。方法利用上海市疾病预防控制中心出生监测系统资料,对2008年杨浦区户籍活产婴儿的出生监测资料进行统计分析。结果 2008年杨浦区户籍人口粗出生率为5.21‰,出生人口性别比为102.85;总生育率为21.64‰,总和生育率为0.81,生育旺盛期出现在25～29岁妇女,出生以初产为主,占93.36%;初产妇为第一胎者占66.65%;新生儿平均出生孕周为38.70周,平均出生体重为3350.50g,正常体重新生儿占89.33%;新生儿畸形发生率为11.39‰;出生人口剖宫产率为67.98%。结论该区生育水平有上升趋势,由于年龄结构的变化,该区将进入周期性生育高峰;提示25～34岁年龄组生育更优生。2008年出生性别比首次达到国际公认值范围;高流产率、高剖宫产率应引起社会关注。
