Further develop New Zealand public health policy on infant bed sharing by quantifying the number of sudden infant death syndrome (SIDS) cases attributable to bed sharing among infants of smoking and nonsmoking mothers.
A large nation-wide case control study covering a region with 78% of all births in New Zealand during 1987-90. Interviews were completed with parents of 393 (81.0% of total) cases who died from the sudden infant death syndrome in the postneonatal age group, and 1592 (88.4% of total) controls who were a representative sample of all hospital births in the study region.
The proportion of control infants who usually bed shared in the last 2 weeks was 65.7% in Maori, 73.7% in Pacific Island people and 35.5% in Europeans (44.5% in all ethnic groups combined, and half of these for less than 2 hours per night). There was an interaction between maternal smoking and infant bed sharing on the risk of sudden infant death separately in Maori, Pacific Island and European infants with the risk being highest in infants exposed to both risk factors. 26% of SIDS deaths were explained by bed sharing among infants of smoking mothers (who comprised 16% of the total infant population) and 3% by bed sharing among infants of non-smoking mothers (28% of total infant population).
Infant bed sharing is common. The majority of SIDS deaths that are attributed to be sharing occur among infants of smoking mothers. A policy which advises all infants not to bed share is estimated to potentially save an extra 3% of SIDS compared to a policy targeted only on infants of smoking mothers. If public attitudes are favorable to bed sharing, there could be a marginal cost (against its acceptance) by including infants of non-smoking mothers in the recommendation not to bed share. These findings should not be interpreted as indicating that bed sharing where the mother is a nonsmoker is safe or protective against SIDS.
通过量化吸烟和不吸烟母亲的婴儿中因同床睡眠导致的婴儿猝死综合征（SIDS）病例数，进一步制定新西兰关于婴儿同床睡眠的公共卫生政策。
一项大型的全国性病例对照研究，涵盖了1987 - 1990年期间新西兰78%出生人口所在的地区。对393例（占总数的81.0%）在新生儿后期死于婴儿猝死综合征的病例的父母进行了访谈，以及对1592例（占总数的88.4%）对照者进行了访谈，这些对照者是研究区域内所有医院出生婴儿的代表性样本。
在过去两周内通常同床睡眠的对照婴儿比例，毛利人为65.7%，太平洋岛民为73.7%，欧洲人为35.5%（所有种族组合为44.5%，其中一半每晚同床睡眠少于2小时）。在毛利、太平洋岛和欧洲婴儿中，母亲吸烟与婴儿同床睡眠对婴儿猝死风险存在交互作用，同时暴露于这两种风险因素的婴儿风险最高。26%的SIDS死亡可归因于吸烟母亲的婴儿同床睡眠（吸烟母亲的婴儿占婴儿总数的16%），3%可归因于不吸烟母亲的婴儿同床睡眠（不吸烟母亲的婴儿占婴儿总数的28%）。
婴儿同床睡眠很常见。大多数归因于同床睡眠的SIDS死亡发生在吸烟母亲的婴儿中。与仅针对吸烟母亲婴儿的政策相比，建议所有婴儿不同床睡眠的政策估计可能额外挽救3%的SIDS病例。如果公众态度有利于同床睡眠，将不吸烟母亲的婴儿纳入不同床睡眠的建议可能会有边际成本（相对于其被接受程度而言）。这些发现不应被解释为表明母亲不吸烟时同床睡眠对SIDS是安全的或有预防作用。
