Education level is associated with the occurrence and timing of hysterectomy: A cohort study of Canadian women
The researchers used data of 30 496 females in the Alberta’s Tomorrow Project to determine the association between level of educational attainment and the occurrence and timing of hysterectomy in Canadian women. They found that women with lower levels of education were more likely to experience hysterectomy, including hysterectomy before menopause and at younger ages.
Association of parity with the timing and type of menopause: A longitudinal cohort study
The study aimed to determine the time-varying association between parity and timing of natural menopause, surgical menopause, and premenopausal hysterectomy among 23,728 women aged 40-65 years at enrollment in the Alberta’s Tomorrow Project cohort study. The researchers found that overall, natural menopause was most common, then premenopausal hysterectomy and surgical menopause. The risk of natural menopause before age 50 was higher for women with 0 or 1 birth, while the risk was similar for those with 3 or more births compared to those with 2 births. Elevated risks of surgical menopause before age 45 for women with 0 or 1 birth were reduced after excluding those with a history of infertility or recurrent pregnancy loss, and the risk decreased over time for women with 3 or more births. Additionally, the risk of premenopausal hysterectomy before age 50 was lower for women with 0 births but increased after age 40 for those with 3 or more births.
