To determine for the period 1973-93, national and regional (1991 and 1992 only) incidence of home birth in New Zealand, with home birth defined as home being the intended place of birth at the onset of labour, to calculate perinatal and maternal mortality rates for home birth, and to categorise the cause of perinatal death.
Data sheets for 9776 planned home births were analysed. These had been collected by the Home Birth Associations of New Zealand/Aotearoa. National perinatal data and data from National Women's Hospital, Auckland were used for comparison. Trend analysis was performed by Poisson regression allowing for overdispersion.
Planned home birth made up 2% of the total births in 1993, up from 0.04% in 1973. The home birth perinatal mortality rate for this period was 2.97 per 1000 total births, with no change over time. This was not significantly different from the rate for a selected low risk group at National Women's Hospital. Lethal anomalies caused 31% of the perinatal deaths. There was one maternal death (maternal mortality rate: 1.02 per 10,000 total births). There were significant differences in the rate of home birth in separate area health board regions for 1991 and 1992.
Home birth was a safe and increasingly popular: though minor, option for New Zealand women from 1973-93.
确定1973 - 1993年期间新西兰全国及地区（仅1991年和1992年）的家庭分娩发生率，家庭分娩定义为分娩发动时预期在家中分娩，计算家庭分娩的围产期和孕产妇死亡率，并对围产期死亡原因进行分类。
分析了9776例计划在家分娩的数据表。这些数据由新西兰/奥特亚罗瓦家庭分娩协会收集。使用全国围产期数据以及奥克兰国家妇女医院的数据进行比较。采用泊松回归进行趋势分析，并考虑过度离散情况。
1993年计划在家分娩占总分娩数的2%，高于1973年的0.04%。该时期家庭分娩的围产期死亡率为每1000例总分娩2.97例，且随时间无变化。这与国家妇女医院选定的低风险组的死亡率无显著差异。致死性畸形导致31%的围产期死亡。有1例孕产妇死亡（孕产妇死亡率：每10000例总分娩1.02例）。1991年和1992年不同地区卫生委员会区域的家庭分娩发生率存在显著差异。
1973 - 1993年期间，家庭分娩对新西兰女性来说是一种安全且越来越受欢迎的选择，尽管规模较小。
