Data Sheet 1_Reproductive life stages and cognitive outcomes: a systematic review in Latin American and Caribbean women.docx

Across studies, shorter reproductive span, earlier menopause, higher parity, surgical menopause, and greater menopausal symptom burden were generally associated with poorer cognitive performance or higher odds of mild cognitive impairment. Some studies suggested favorable associations between menopausal hormone therapy use and cognitive outcomes. Postmenopausal factors, such as sarcopenia and obesity, as well as a longer duration of menopause, were predominantly linked to poorer cognitive outcomes.

Only one population-based cohort evaluated incident dementia, underscoring the scarcity of longitudinal evidence in the region. Overall, the evidence suggests that reproductive life stages in LAC women are meaningfully associated with cognitive outcomes, reflecting the influence of hormonal transitions, menopausal characteristics, and postmenopausal health within distinctive regional contexts. However, the predominance of cross-sectional designs and limited regional representativity, coupled with a lack of integrated physiological indicators, reveal a substantial knowledge gap.

Longitudinal and regionally representative cohorts incorporating standardized assessments of reproductive life stages alongside comprehensive cognitive measures are essential to understanding how reproductive life stages shape cognitive outcomes in LAC women.</p><p>Systematic review registration: The systematic review was registered in the Open Science Framework (OSF).
