Postpartum depression (PPD) affects nearly 20% of postpartum women and has severe short- and long-term detrimental effects on their mental health. While there is ample evidence linking depression-related outcomes and individuals’ socioeconomic status (SES), the examination of differences in PPD as a function of SES has received relatively little empirical attention, resulting in inconsistent empirical evidence. There are also no well-established systematic reviews on the linkage between SES and PPD. Thus, we conducted A PRISMA-compliant systematic review to comprehensively analyze the association of SES (as measured by long-established objective [e.g., income or education] and subjective measures) with PPD (as measured by widely validated scales). We performed a bibliographic search on CINAHL Complete, MEDLINE complete, and EBSCO Psychology and Behavioral Sciences Collection. Among the 201 articles retrieved, 16 met the eligibility criteria. Our results reveal that mothers with lower income and education levels (objective indicators of SES) were more likely to experience PPD. Notably, we also found that subjective SES, compared to objective SES, was more strongly associated with PPD. Overall, these findings indicate that low-SES mothers may be at increased risk of PPD compared to high-SES mothers, reflecting the need for more efficient early detection programs for PPD among low-SES mothers.

产后抑郁症 (PPD) 影响着近 20% 的产后女性，并对她们的心理健康产生严重的短期和长期有害影响。虽然有充足的证据将抑郁症相关结果与个人的社会经济地位 (SES) 联系起来，但对 PPD 差异作为 SES 函数的研究相对较少受到实证关注，导致实证证据不一致。对于 SES 和 PPD 之间的联系也没有完善的系统评价。因此，我们进行了符合 PRISMA 标准的系统评价，以全面分析 SES（通过长期建立的客观[例如收入或教​​育]和主观测量来衡量）与 PPD（通过广泛验证的量表来衡量）之间的关联。我们对 CINAHL Complete、MEDLINE Complete 和 EBSCO Psychology and Behavioral Sciences Collection 进行了书目检索。检索到的 201 篇文章中，有 16 篇符合资格标准。我们的结果显示，收入和教育水平（社会经济地位的客观指标）较低的母亲更有可能经历产后抑郁症。值得注意的是，我们还发现，与客观 SES 相比，主观 SES 与 PPD 的相关性更强。总体而言，这些研究结果表明，与高 SES 母亲相比，低 SES 母亲患 PPD 的风险可能更高，这反映出低 SES 母亲需要更有效的 PPD 早期检测计划。
