This paper reviews the data available in New South Wales on teenage fertility rates and pregnancy outcomes. Teenage births comprise six per cent of all births in New South Wales, but they constitute a significant public health problem because they are associated with elevated rates of adverse pregnancy outcomes, which include low birthweight, perinatal death and pre-eclampsia. Risk is concentrated in females under 18 years of age. Pregnancy outcomes for females aged 18 to 19 years are similar to those of women aged 20 to 24 years. Teenage fertility rates have remained stable since the mid-1980s, following a decline which began in the early 1970s. There are large geographic variations in teenage fertility within the state, with the highest rates in the far west of New South Wales and in western Sydney. Teenage pregnancy in New South Wales (as distinct from fertility which reflects births) cannot be assessed accurately because of the lack of information on terminations of pregnancy. However, available data suggest that teenage pregnancy rates have not increased during the 1980s.
本文回顾了新南威尔士州有关青少年生育率和妊娠结局的现有数据。青少年生育占新南威尔士州所有出生人口的6%，但它们构成了一个重大的公共卫生问题，因为它们与不良妊娠结局的高发生率相关，这些不良妊娠结局包括低出生体重、围产期死亡和先兆子痫。风险集中在18岁以下的女性。18至19岁女性的妊娠结局与20至24岁女性的相似。自20世纪80年代中期以来，青少年生育率一直保持稳定，此前在20世纪70年代初开始下降。该州青少年生育率存在很大的地理差异，新南威尔士州最西部和悉尼西部的生育率最高。由于缺乏关于妊娠终止的信息，新南威尔士州的青少年怀孕情况（与反映出生情况的生育率不同）无法准确评估。然而，现有数据表明，20世纪80年代青少年怀孕率并未上升。
