Unintentional injury among infants is a major public health issue; however, the relationship between unintentional infant injury and postpartum depression remains unclear. In this study, we aim to investigate the association between the two.
We administered an original questionnaire to mothers participating in a 3- or 4-month health check-up program (target n = 9707). This questionnaire assessed infant health, including types of unintentional injury experiences used in previous study, and maternal mental health such as postpartum depression, by the validated screening tool, the Edinburgh Postnatal Depression Scale (EPDS). Associations between infant injury and postpartum depression were assessed using logistic regression adjusted for covariates, including parental, infant, and household characteristics.
In total, 6534 women responded to the questionnaire with valid answers on the EPDS (valid response rate, 67 %). Of the sample, 9.8 % of infants experienced unintentional injury (fall: 5.6 %; near-drowning: 1.2 %), and 9.5 % of mothers had postpartum depression (EPDS score of 9+). After adjusting for covariates, postpartum depression was significantly positively associated with any unintentional injury (odds ratio [OR] 1.59, 95 % confidence interval [CI] 1.24-2.04), and falls (OR 1.41, 95 % CI 1.02-1.95), although near-drowning was not significantly associated.
Postpartum depression might be a risk factor for unintentional injury of infants aged up to 4 months. Further prospective studies are needed to confirm the association between postpartum depression and unintentional injury of infants.
婴儿意外伤害是一个主要的公共卫生问题；然而，婴儿意外伤害与产后抑郁之间的关系仍不明确。在本研究中，我们旨在调查两者之间的关联。
我们向参加3或4个月健康检查项目的母亲发放了一份原始问卷（目标样本量n = 9707）。该问卷通过经过验证的筛查工具爱丁堡产后抑郁量表（EPDS）评估婴儿健康，包括先前研究中使用的意外伤害经历类型，以及母亲的心理健康状况，如产后抑郁。使用对包括父母、婴儿和家庭特征等协变量进行调整的逻辑回归来评估婴儿伤害与产后抑郁之间的关联。
共有6534名女性对问卷做出回应，且在EPDS上有有效答案（有效回复率为67%）。在样本中，9.8%的婴儿经历过意外伤害（跌倒：5.6%；溺水未遂：1.2%），9.5%的母亲有产后抑郁（EPDS评分≥9分）。在对协变量进行调整后，产后抑郁与任何意外伤害（优势比[OR] 1.59，95%置信区间[CI] 1.24 - 2.04）以及跌倒（OR 1.41，95% CI 1.02 - 1.95）显著正相关，尽管溺水未遂与之无显著关联。
产后抑郁可能是4个月及以下婴儿意外伤害的一个风险因素。需要进一步的前瞻性研究来证实产后抑郁与婴儿意外伤害之间的关联。
