The Jamaican Perinatal Mortality Survey collected data that have been used in this paper to estimate: (1) the rate of multiple deliveries on the island; (2) the way in which this varies with demographic features; and (3) the causes of perinatal mortality among twins on the island. The survey consisted of two phases: a study of all births in the months of September and October 1986 (the cohort months) and a study of all perinatal deaths in the 12 months from 1 September 1986 to 31 August 1987. Among the 10,408 pregnancies in the cohort months, 99(1.0%) were multiple pregnancies. The twinning rate showed statistically significant trends with maternal age and parity but no association with social factors. Among the 2020 perinatal deaths occurring in the 12-month period, 173 (8.6%) were twins, with particularly high contribution to the Wiggles-worth group 'deaths from immaturity'. Mortality rate of twins was significantly lower if mothers resided in areas where there were good obstetric and paediatric facilities.
牙买加围产期死亡率调查收集的数据已用于本文，以估计：（1）该岛多胎分娩率；（2）其随人口特征变化的方式；（3）该岛双胞胎围产期死亡原因。该调查包括两个阶段：对1986年9月和10月（队列月份）的所有出生情况进行研究，以及对1986年9月1日至1987年8月31日这12个月内所有围产期死亡情况进行研究。在队列月份的10408例妊娠中，99例（1.0%）为多胎妊娠。双胎率在统计学上显示出与母亲年龄和产次有显著趋势，但与社会因素无关。在这12个月期间发生的2020例围产期死亡中，173例（8.6%）为双胞胎，对威格尔斯沃思组“未成熟死亡”的贡献尤为突出。如果母亲居住在有良好产科和儿科设施的地区，双胞胎的死亡率会显著降低。
