Abstract

Objective: To describe subdermal implant use in Mexico over time, by state and by age. Methods: We conducted a repeated cross-sectional study using the 2009, 2014, and 2018 waves of the National Survey of Demographic Dynamics (Encuesta Nacional de la Dinámica Demográfica [ENADID]). Our outcome was current use of contraception, by type, with a focus on the implant. We used visualizations, descriptive and bivariate statistics, and multinomial models to assess change over time, geographic patterns, method mix, and factors associated with implant use (vs intrauterine device [IUD] or other hormonal methods). Results: Implant use is increasing over time in Mexico, from 1.1% of women who have ever used a method in 2009 to 4.5% in 2018 (P < 0.001); the change is greatest among adolescents (2.5% in 2009 to 12.2% in 2018; P < 0.001). Change in implant use as a fraction of modern method use was heterogeneous across Mexican states. The adjusted relative likelihood of using an implant compared with IUD was 34% higher for adolescents compared with women aged 20–29 years (relative risk ratio 1.34, 95% confidence interval 1.16–1.55, P < 0.001), controlling for other variables in the model. Conclusion: Use of subdermal implants is increasing over time in Mexico and is concentrated among adolescents. Implants have the potential to expand access to highly effective contraception in Mexico.
