BACKGROUND: Oral combined hormonal contraceptives (CHCs) are one of the most used contraceptive methods worldwide, however, their use may have accessory effects that can generate metabolic, inflammatory, and vascular alterations.OBJECTIVE: To evaluate the association of cardiovascular risk factors, Ultra-sensitive C-reactive protein (US-CRP), and brachial artery flow-mediated dilation in patients using hormonal contraceptives.DESING AND SETTING: This was a cross-sectional study including 109 women (18 to 40 years old) conducted between August 2017 and January 2020 who were assisted at the Brazilian Public Health System in countryside city in northeastern of Brazil.METHODS: The volunteers were divided into two groups according to the use of CHCs and submitted to measurement evaluations of clinical, laboratory, and flow-mediated dilation (FMD) of the brachial artery parameters. RESULTS: The statistical analysis of results between groups showed the following results as total cholesterol (P = < 0.01), high-density lipoprotein, HDL (P = 0.01), triglycerides, TG (P < 0.01), and US-CRP (P = < 0.01). The FMD measurement showed changes in 37.75% (n = 20) of women who were not using CHCs and in 32.15% (n = 18) of women using CHCs (P = 0.37) (odds ratio, OR = 0.78). There were no significant changes between glycemic indexes and parameters clinicals.CONCLUSION: Users of CHCs showed higher levels of total cholesterol, HDL, and triglycerides compared to those who did not use it. The US-CRP results showed a significant increase among CHCs users, however, no change between the FMD values was observed.
Objective: The goal of this revision is to explain if the use of combined hormonal contraceptives (CHCs) can be correlated to metabolic alterations that may have an association on the occurrence of metabolic syndrome. Methods: Articles published between January 2008 and September 2020 identified in Google Scholar, Scielo, Pubmed, and Cochrane databases were enlisted and narrowed down to 28 selected articles and one Ph.D. thesis. Results: The use of CHCs may influence carbohydrate metabolism, lipid profile, and changes in C-reactive protein (CRP), however, the influence of CHCs on abdominal circumference, blood pressure, and the prevalence of metabolic syndrome is unclear. Conclusions: The results found were controversial in most of the investigated cases of metabolic alterations. Therefore, there is no association between the use of CHCs and the occurrence of metabolic syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
