Characteristics of study participants (N = 540).

Postpartum depression (PPD) affects 10–15% of women globally and up to 35% in Bangladesh, yet remains under-researched across different healthcare settings. This cross-sectional study aimed to assessed the prevalence and its socio-demographic and obstetric correlates among 540 women attending tertiary, secondary, and primary healthcare centers for routine post-natal care in Bangladesh, 4–12 weeks after delivery. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for PPD (cut-off ≥10), and socio-demographic, reproductive, and obstetric data were collected through structured questionnaires. Logistic regression identified significant predictors of PPD. The prevalence of PPD was 47.78% (95% CI: 43.49–52.09), with 29.07% experiencing major depression (EPDS ≥13). Women engaged in labor work (AOR = 5.17, 95% CI: 1.70–15.70, p = 0.01), having a previous history of depression (AOR = 3.38, 95% CI: 2.17–5.28, p产后抑郁（Postpartum Depression, PPD）在全球范围内影响10%至15%的女性群体，在孟加拉国这一比例甚至高达35%，但目前针对不同医疗场景下的产后抑郁相关研究仍相对匮乏。本横断面研究旨在评估孟加拉国540名于产后4至12周前往三级、二级及基层医疗中心接受常规产后护理的女性的产后抑郁患病率，及其社会人口学与产科相关关联因素。研究采用爱丁堡产后抑郁量表（Edinburgh Postnatal Depression Scale, EPDS），以临界值≥10分作为筛查标准对PPD进行筛查，并通过结构化问卷收集研究对象的社会人口学、生殖及产科相关数据。采用Logistic回归分析筛选产后抑郁的显著预测因素。本研究中产后抑郁的患病率为47.78%（95%置信区间（Confidence Interval, CI）：43.49–52.09），其中29.07%的研究对象符合重度抑郁筛查标准（EPDS≥13分）。从事体力劳动的女性（调整后优势比（Adjusted Odds Ratio, AOR）=5.17，95%CI：1.70–15.70，p=0.01）、既往有抑郁病史的女性（AOR=3.38，95%CI：2.17–5.28，p
