To examine the association between preterm delivery and parental separation and identify associated risk factors.
All opposite sex, married or common-law parents whose relationship status was available at index delivery and for the next 5 years were eligible in this retrospective population-based cohort study in Manitoba, Canada. Parents of children born preterm were matched 1:5 to parents of children born full-term. Parental separation within 5 years of childbirth was the primary outcome. Secondary outcome was the time to separation. Multivariable Poisson regression model was created to estimate the 5-year incidence rate ratios (IRR) of the primary outcome.
Parents of 6367 children born preterm (n=164 for <28 weeks, n=1196 for 28-33 weeks, n=5007 for 34-36 weeks) and parents of 30 663 children born full-term were included. Compared with parents of children born term (4.2%), only parents of children born at 34-36 weeks had a higher incidence rate of separation (5.5%, IRR: 1.26; 1.09-1.45, p=0.002), although parents of children born at 28-33 weeks (5.4%, IRR: 1.20; 0.93-1.55, p=0.16), and at<28 weeks (5.5%, IRR: 1.27; 0.66-2.45, p=0.48) had similar IRRs. Time to separation was similar between all groups.
Parents of children born at 34-36 weeks had higher separation rates than parents of children born full-term. The risk factors identified can be used to identify and provide supports to at-risk parents.
探讨早产与父母分居之间的关联，并确定相关风险因素。
在加拿大曼尼托巴省的这项基于人群的回顾性队列研究中，所有在分娩时及随后5年内其关系状况已知的异性已婚或同居父母均符合条件。早产儿童的父母与足月产儿童的父母按1:5进行匹配。分娩后5年内父母分居是主要结局。次要结局是分居时间。建立多变量泊松回归模型以估计主要结局的5年发病率比（IRR）。
纳入了6367名早产儿童（孕周<28周的有164名，28 - 33周的有1196名，34 - 36周的有5007名）的父母以及30663名足月产儿童的父母。与足月产儿童的父母（4.2%）相比，只有34 - 36周出生儿童的父母分居发生率更高（5.5%，IRR：1.26；1.09 - 1.45，p = 0.002），尽管28 - 33周出生儿童的父母（5.4%，IRR：1.20；0.93 - 1.55，p = 0.16）以及<28周出生儿童的父母（5.5%，IRR：1.27；0.66 - 2.45，p = 0.48）的IRR相似。所有组之间的分居时间相似。
34 - 36周出生儿童的父母分居率高于足月产儿童的父母。所确定的风险因素可用于识别有风险的父母并为其提供支持。
