Objectives. To describe patterns of providing moderately effective versus the most effective contraception and of providing implants versus intrauterine devices in US community health centers. Methods. We conducted a historical cohort study (2017-2019). Outcomes were woman-level receipt of most effective contraception (long-acting reversible contraception; implants and intrauterine devices) or moderately effective contraception. We used logistic regression to identify patient and clinic factors associated with providing (1) most versus moderately effective methods, and (2) implants versus intrauterine devices. We calculated adjusted probabilities for both outcomes by age group. Results. We included 199 652 events of providing contraception to 114 280 women in 410 community health centers. Adjusted probabilities were similar across age groups for moderately versus most effective methods. However, the adjusted marginal means for receiving an implant compared with an intrauterine device were highest for adolescents (15-17 years: 78.2% [95% confidence interval (CI) = 75.6%, 80.6%]; 18-19 years: 69.5% [95% CI = 66.7%, 72.3%]). Women's health specialists were more likely to provide most versus moderately effective contraception. Conclusions. Community health centers are an important access point for most effective contraception for women of all ages. Adolescents are more likely to use implants than intrauterine devices.
