Abstract

ObjectiveTo conduct a secondary analysis of continuation, unwanted effects and cost consequences at 1 year in copper intrauterine device (IUD) users aged under 30 in the European Active Surveillance Study for Intrauterine Devices (EURAS-IUD study) based on IUD type.MethodsDescriptive and comparative analyses of copper IUD continuation, unwanted effects and estimated cost consequences at 1 year were performed in users aged under 30 based on IUD copper surface area, shape or design, width and arms’ flexibility.Results5796 copper IUD users were identified to have been aged under 30 at EURAS-IUD study recruitment and data for 5762 users (99.4%) was analysed. Higher IUD continuation, fewer unwanted effects and lower costs were observed with IUDs of the lowest copper content (<300mm2), horse-shoe frame design, widths 18 mm to <30mm and flexible IUD arms. Discontinuation, unwanted effects and costs were greater with frameless IUDs and framed, ≥30mm width IUDs with 380mm2 of copper and copper bands on their rigid transverse IUD arms.ConclusionsSignificant differences in continuation, reported unwanted effects and estimated costs at 1 year between IUD types were observed in users aged under 30. Although further research is needed, clinicians should consider these findings when counselling and choosing IUD types for younger women.
