Abstract: Objectives To analyse whether socioeconomic conditions, experienced by mothers and adult daughters during their childhood, are associated with age at menarche (AAM) in daughters. Methods From September 2011 to January 2014, we collected recalled AAM and childhood living conditions data from a sample of 260 dyads of Maya mothers (mean age = 60 years) and their adult daughters (mean age = 33 years) from the cities of Merida and Motul in Yucatan, Mexico. Indicators of childhood living conditions were number of siblings, quality of construction materials of the house, and father’s absence when these women were pre-menarcheal girls. One-way ANOVA and multiple regression models were used to assess the association between childhood conditions and daughters’ AAM. Results The recalled mean AAM of adult Maya daughters was 12.05 years (SD = 1.53). After adjusting for the influence of mothers’ AAM, number of siblings in either the mothers’ and daughters’ families directly predicted daughters’ AAM (more siblings - later AAM); and better household conditions index of mothers was associated to earlier AAM in daughters. Household conditions index, during the childhood of daughters, and father’s absence were not associated with their AAM. Conclusions After controlling for the influence of maternal AAM and father’s absence at household during pre-menarcheal stage, our results suggest that better living conditions experienced by mothers and daughters during their childhood are associated to lower mean AAM in daughters.
