Investigating the Relationship between the Use of Oral Contraceptive Pills and Metabolic Syndrome in the Tabari Cohort Population: A Cross-Sectional-Descriptive Study

Background and purpose: Metabolic syndrome (MetS) refers to a combination of metabolic disorders which is considered a set of risk factors for chronic diseases such as cardiovascular disease and type 2 diabetes. Oral contraceptive pills (OCPs) are one of the most popular and effective methods of preventing pregnancy. The aim of this study is to investigate the relationship between the use of OCPs and MetS in the Tabari cohort population. Materials and methods: The current cross-sectional study utilized data collected in the enrolment phase of the Tabari cohort study (TCS). In total data of 5979 women aged 35 to 70 years were analyzed. The obtained data were analyzed using Chi-square tests and logistic regression analysis to assess the relationship between the use of OCPs and its duration with the risk of MetS and its components. Results: The prevalence of MetS among women participated in TCS was 49% (2930 individuals). The frequency of OCPs consumption was 42.9% (2563 individuals). The average duration of OCP use in women with and without MetS was 69.15±67.06 71.46±68.38 months respectively (P=0.388). After adjusting of confounding variables, no statistically significant association was observed between the use of OCPs and MetS and its parameters (except blood pressure). Similarly, the duration of taking these pills was also not significantly associated with MetS and these parameters. Conclusion: The use of oral contraceptives is not associated with MetS and other parameters, but its use, especially in the long term, can be accompanied by high blood pressure.
