Prevalence of hysterectomy and its determinants in northern Iran: enrollment results of the Tabari cohort study

To the best of our knowledge, no population-based studies have provided insights into the prevalence of hysterectomy and its risk factors among northern Iranian females. Thus, the present study aimed to investigate the prevalence and sociodemographic determinants of hysterectomy in a large cohort of northern Iranian females.

This cross-sectional study included data from the enrollment phase of the Tabari cohort study (TCS). The TCS consists of 10,255 adults (4,149 males and 6,106 females) aged 35–70 years who reside in Sari, Mazandaran, Iran, of which 6103 females were included in the study. Multiple logistic regression analysis was used to search for hysterectomy determinants.

Our results revealed that the prevalence of hysterectomy among northern Iranian females was 9.7% (595/6103). Additionally, 50–59 (OR: 4.63, 95% CI: 3.57–6.01) and 60–70 (OR: 5.83, 95% CI: 4.28–7.95) age groups, higher socioeconomic levels (OR: 1.66, 95% CI: 1.13–2.42), a history of tubectomy (OR: 1.27, 95% CI: 1.05–1.53), and more gravida (OR: 5.35, 95% CI: 1.62–17.63) were found to increase the odds of hysterectomy, whereas living in mountainous areas (OR: 0.57, 95% CI: 0.43–2.75) and having a job (OR: 0.62, 95% CI: 0.45–0.86) were found to decrease the odds of hysterectomy.

Older age groups, living in urban areas, higher socioeconomic levels, not having a job, a history of tubectomy, and more gravida were found to increase the odds of hysterectomy.
