Evolutionary anthropology offers a social framework for perinatal mental health

The authors use evolutionary anthropology to broaden explanations for perinatal depression and anxiety, which they describe as multifactorial. They propose that mothers in Western, Educated, Industrialised, Rich and Democratic (WEIRD) societies may experience a mismatch between largely individualised child-rearing and the extensive shared caregiving that characterised much of human evolutionary history. The article is a conceptual argument, not a clinical study or intervention evaluation.

The authors cite anthropological observations of hunter-gatherer communities, including reports that BaYaka children typically receive care from around eight other caregivers per day, who provide close to half of their care. They contrast this with the lower availability of family and community support, trusted parenting advice and prior caregiving experience reported by many mothers in high-income societies. They suggest these differences may contribute to distress, alongside other established factors; they do not claim that reduced support is the sole cause or that rates are highest in WEIRD societies.

The authors propose using this framework in consultations to help explain how isolation and intensive-mothering expectations may contribute to distress, rather than framing difficulties as personal failure. These proposals are not evidence of an effective treatment, and the article presents no tested intervention or quantified estimate of effect. Its claims should be understood as a plausible explanatory framework, not proof that evolutionary mismatch causes perinatal disorders.
