Menopausal age as an indicator of healthy aging is a complex phenomenon. However, there is no consensus on its contributing factors. This study aimed to determine  age at menopause and its determinants in 1930 menopausal women participating in the Hoveyzeh Cohort Study (HCS), Hoveyzeh, South west Iran. HCS was conducted in Hoveyzeh County from May 2016 to August 2018. By door-to-door census, eligible people were identified. In this population-based cross-sectional study, interviewer-administered questionnaires were used for data collection. Principle component analysis (PCA) was used for estimation of wealth index quintiles. SPSS 23 software was used to analyze the data. The chi-square test, independent, and one-way analysis of variance were used. The odds ratio was calculated using univariate and multivariate regression. The mean age of natural menopause was 49.46 (SD=4.48), with a median of 50 years. Premature menopause was reported in 6.6% (155) of women. The wealth index and its components had no significant association with the natural age at menopause (P>0.05). The mean and median age of natural menopause was within the range reported in previous studies. Further studies are recommended to determine the definite effect of social factors on menopausal age.
