目的 探讨非计划妊娠对产后抑郁的影响,为预防产后抑郁提供科学依据,方法 选取2013年2月-2014年2月在该院进行42 d体检的1 139例产妇为研究对象,采用爱丁堡产后抑郁量表(EPDS)评估产妇的抑郁情绪,将评分≥10分界定为有抑郁情绪.收集产妇的社会人口学资料、妊娠计划性、不良孕产史等情况,采用二元非条件Logistic回归模型进行分析.结果 意外妊娠者198例(17.4％),顺其自然妊娠608例(53.4％),计划妊娠333例(29.2％),意外妊娠,顺其自然妊娠妇女较计划妊娠妇女年龄小、受教育程度和家庭收入低,并且农村户口占的比例很高.意外妊娠产妇产后抑郁的检出率高于其他两组.调整相关混杂因素后,经二元Logistic回归模型分析显示:意外妊娠、顺其自然妊娠是产后抑郁的危险因素,OR值(95％GI)分别为1.982、1.420,差异具有统计学意义(P＜0.05).结论 非计划妊娠会增加产后抑郁的风险.“,”Objective To explore the effect of unintended pregnancy on postpartum depression,and provide a scientific basis for prevention of postpartum depression.Methods A total of 1 139 postpartum women receiving physical examination in Maanshan Maternal and Child Health Care Hospital at 42 days after delivery from February 2013 to February 2014 were selected.Edinburgh Postpartum Depression Scale (EPDS) was used to evaluate postpartum depression.The postpartum women with EPDS score ≥ 10 were defined as depression.Demographic data,pregnancy intention,and adverse pregnancy history were collected.Binary nonconditional logistic regression model was used to analyze the data.Results The incidence rates of unintended pregnancy,natural pregnancy,and intended pregnancy were 17.4％ (198 women),53.4％ (608 women),and 29.2％ (333 women),respectively.The women of unintended pregnancy and natural pregnancy were younger than the women of intended pregnancy,the educational level and family income of women of unintended pregnancy and natural pregnancy were lower than those of intended pregnancy,the proportion of women with rural household registration was high.The detection rate of postpartum depression in unintended pregnancy group was higher than those in the other two groups.After adjusting the related confounding factors,binary logistic regression analysis showed that unintended pregnancy and natural pregnancy were risk factors of postpartum depression (OR:1.982,1.420,P＜0.05),respectively.Conclusion Unintended pregnancy can increase the risk of postpartum depression.
