Objective: The purpose of this study was to examine age at natural menopause among women of Maya and non-Maya ancestry living in urban and rural communities in the state of Campeche, Mexico. Methods: Women ages 40 to 60 (n = 543) participated in semi-structured interviews and anthropometric measures. The last names, languages spoken, and the birthplace of the woman, her parents, and her grandparents were used to determine Maya or non-Maya ethnicity. Recalled age at natural menopause was compared across four communities; analysis of variance was used to compare means and Kaplan-Meier analyses were used to compare medians. Probit analysis was also used to estimate median ages at menopause. Cox regression analyses were applied to identify variables associated with age at menopause. Results: Mean recalled age at natural menopause across all sites was 46.7 years, ranging from 47.8 years in the city of Campeche to 43.9 years in the rural Maya communities in the municipality of Hopelchén. Median ages at menopause across all sites were 50.55 years by probit analysis and 50.5 years by Kaplan-Meier. Variables associated with a later age at menopause included higher socioeconomic status, higher parity, and a later age at menarche. Conclusions: The early mean recalled age at menopause in southern Hopelchén was consistent with previous studies in the Yucatán peninsula. As expected, probit and Kaplan-Meier analyses demonstrated later ages at menopause. Contrary to our expectations, Maya/non-Maya ethnicity was not associated with age at menopause. Demographic and reproductive factors were more important than ethnicity in explaining variation in age at menopause within the state of Campeche, Mexico.

Objectives:To assess how different variables experienced across the life course, but particularly during early life, might affect age at menopause among 174 Bangladeshi migrants to London by comparing them to 157 nonmigrant sedentees and 154 women of European descent in London.Methods:Participants were aged 35–59 years, with no exogenous hormone use in the past three months, not pregnant or lactating, with no history of hysterectomy or oophorectomy. Face‐to‐face interviews and anthropometric measures were carried out. In addition to mean recalled age at natural menopause, median age was computed by probit analysis. Ages at menopause were examined by bivariate and Cox regression analyses in relation to demographic, reproductive, and lifestyle variables, and in relation to potential exposure to cyclones in early childhood.Results:Ages at menopause were significantly earlier among Bangladeshi sedentees and immigrants compared to Londoners of European origin. Ages at menopause were earlier among sedentees compared to immigrants. Urban birthplace, more infectious diseases during childhood, and lower levels of education increased the risk of an earlier menopause.Conclusions:Changes in environmental conditions during adulthood appeared to modify age at menopause among Bangladeshi immigrants in London compared to women living in Bangladesh; however, Bangladeshi immigrants still experienced an earlier age at menopause compared with their London neighbors of European descent.

Variation in levels of AMH among Maya and non‐Maya women in Campeche, Mexico

Increasing age and progression through the menopausal transition were both associated with declining levels of AMH. The association between Maya ethnicity and a lower likelihood of detecting AMH is consistent with the early ages at menopause reported in previous studies. We considered a rapid life history model as an explanatory framework, and suggest, from an ecological perspective, that future research should consider measures of developmental stress that may compromise ovarian reserves.
