背景：本研究旨在探讨非意愿妊娠与母亲行为的关系。研究设计：对2001年至2006年期间分娩活产婴儿的9048名母亲进行分层随机抽样，并在分娩后2至9个月完成妊娠风险评估监测系统（PRAMS）调查。采用二进制和有序逻辑回归方法与适当的调查权重，以控制社会人口因素。与计划怀孕的妇女相比，意外怀孕的母亲更有可能摄入少于推荐量的孕前叶酸[调整后的比值比（OR）2.39，951%置信区间（CI）1.7-3.2]，产前吸烟（OR 2.03 95% CI 1.5-2.9），产后吸烟（OR 1.86，95% CI 1.35-2.55）并报告产后抑郁症（OR 1.98，95%CI 1.48-2.64）;在怀孕的头三个月，（OR 0.34，95% CI 0.3-0.5）和母乳喂养8周或更长时间（OR 0.74，95% CI 0.57-0.97）。与有意怀孕的妇女相比，妇女与不合时宜的怀孕也更有可能消耗叶酸不足，延迟产前护理和报告产后depress.Conclusion：即使在控制了多种社会人口因素，意外和不合时宜的怀孕与围产期不健康的行为。(C)2009 Elsevier Inc.

Background: This Study was conducted to determine the relationship between unintended pregnancy and maternal behaviors bet-ore. during and after pregnancy.Study Design: Data were analyzed from a stratified random sample of 9048 mothers who delivered live born infants between 2001 and 2006 and completed the Pregnancy Risk Assessment Monitoring System (PRAMS) Survey 2 to 9 months after delivery. Binary and ordinal logistic regression methods with appropriate survey weights were used to control for socio-demographic factors.Results: Compared to women with intended pregnancies, mothers with unwanted pregnancies were more likely to consume less than the recommended amount of preconception folic acid [adjusted odds ratio (OR) 2.39, 951% confidence interval (CI) 1.7-3.2], smoke prenatally (OR 2.03 95% CI 1.5-2.9), smoke postpartum (OR 1.86, 95% CI 1.35-2.55) and report postpartum depression (OR 1.98, 95% CI 1.48-2.64); they were less likely to initiate prenatal care during the first trimester (OR 0.34, 95% CI 0.3-0.5) and breastfeed for 8 or more weeks (OR 0.74, 95% CI 0.57-0.97). Compared to women with intended pregnancies, women with mistimed pregnancies were also more likely to consume inadequate folic acid, delay prenatal care and report postpartum depression.Conclusion: Even after controlling for multiple socio-demographic factors, unwanted and mistimed pregnancies were associated with unhealthy perinatal behaviors.
