    Summary
    This summary is machine-generated.

    This study followed 1462 women in Sweden to understand menopause timing. Results indicate a median menopausal age between 49 and 50.5 years, with no strong evidence of significant changes over time.

    Area of Science:

    • Reproductive Health
    • Epidemiology
    • Gerontology

    Background:

    • Understanding menopausal age is crucial for women's health and reproductive studies.
    • Previous research suggested potential shifts in menopausal age, necessitating population-based validation.

    Purpose of the Study:

    • To investigate the menopausal age in a Swedish population cohort.
    • To determine if menopausal age has changed over time in women born in different years.

    Main Methods:

    • A longitudinal population study of 1462 women in Goteborg, Sweden, conducted in 1968-1969 and re-studied in 1974-1975.
    • Data collection included menopausal status and age at menopause for postmenopausal women.
    • Analysis focused on five age strata (38, 46, 50, 54, 60 years) and women born in specific years (1908-1930).

    Main Results:

    • High participation rate (90.1%) and good agreement between study years.
    • The vast majority of women experienced a spontaneous menopause.
    • Median menopausal age ranged from 49 years 7 months to 50 years 5 months.
    • A slight tendency for increased menopausal age was observed in some birth cohorts, but not consistently across all groups.

    Conclusions:

    • The study did not support the view that menopausal age is rapidly changing in this population.
    • Findings suggest relative stability in menopausal age within the studied cohorts.
    • Further research may be needed to explore subtle demographic influences on menopausal timing.
