Abstract
Background: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of reproductive-age women, affecting roughly 10% worldwide. The demographic, clinical, and lifestyle factors associated with PCOS in the Iranian population remain incompletely characterized, particularly at the population level.

Objectives: We aimed to characterize the demographic, clinical, and lifestyle factors associated with PCOS in a large Iranian population-based sample.

Methods: We conducted a cross-sectional, registry-based study using routinely collected data from 12,391 women aged 15–50 years (3,098 with PCOS and 9,293 without) who attended primary-care centers affiliated with Mashhad University of Medical Sciences between March 2017 and June 2023. Records were extracted from the Sina Electronic Health Record system. An ICD-10-CM code of E28.2 defined cases. Associations between candidate factors and PCOS were examined using χ² tests and multivariable logistic regression, reporting adjusted odds ratios (AOR) with 95% confidence intervals (CI).

Results: PCOS was most frequent among women aged 31–40 years (53.2% of cases; AOR 1.99, 95% CI 1.54–2.59 versus <20 years). Obesity was independently associated with PCOS (AOR 1.45, 95% CI 1.26–1.66), and 57.0% of cases were overweight or obese. Regular fast-food consumption raised the odds of PCOS both monthly (AOR 1.56, 95% CI 1.27–1.92) and weekly (AOR 1.41, 95% CI 1.25–1.59). Hypertension (AOR 1.72, 95% CI 1.38–2.15) and anemia (AOR 1.40, 95% CI 1.22–1.60) were also independently associated with PCOS. A history of abortion showed a dose-response pattern, with AORs rising from 1.35 (one abortion) to 1.63 (three or more).

Conclusion: In this large registry-based sample, PCOS was independently associated with several modifiable factors, obesity, frequent fast-food intake, and reproductive history—alongside coexisting hypertension and anemia. These findings support integrated preventive strategies centered on weight management, dietary modification, and comprehensive reproductive-health care. Because of the cross-sectional design, associations should not be interpreted as causal. Future research should employ longitudinal designs to clarify the causal pathways underlying these associations.
