RESUMO
BACKGROUND: Adolescent girls and young women experience high rates of sexually transmitted infection (STI) with currently available contraceptive methods, yet few studies examine the burden of chlamydial infection by contraceptive method used. MATERIALS AND METHODS: In this cross-sectional analysis, we linked July 2012-June 2013 claims from a publicly-funded family planning program in California to chlamydia laboratory test results. Female clients were classified by the most effective contraceptive method reported by providers during the year: tier 1 (high-efficacy permanent or long-acting reversible methods), tier 2 (shorter-acting hormonal methods), or tier 3 (barrier methods, emergency contraception, or natural family planning). In addition, we identified clients who received condoms from providers. We used log-binomial models to estimate adjusted prevalence ratios comparing chlamydia positivity by contraceptive method(s). RESULTS: Of 74,636 female clients of ages 15-29 years with chlamydia test results, 5.1% had at least one positive test during the year. Chlamydia positivity was highest among tier 2 users (5.3%) compared with 4.5% and 4.9% among tiers 1 and 3 users, respectively (p < 0.001). Positivity was higher among clients who received condoms from providers than those who did not (6.3% vs. 4.3%, p < 0.001). In adjusted analyses, there were no significant differences in positivity by contraceptive tier. However, clients who received condoms had 1.32 (95% confidence interval: 1.24-1.40) times the positivity of those who did not. CONCLUSIONS: We found high chlamydia positivity among young female family planning clients regardless of contraceptive method. The development and provision of additional Multipurpose Prevention Technologies that confer protection against both pregnancy and STIs may help to address unmet need for STI prevention.

In the USA, family planning clinics are primary providers of reproductive healthcare to young women and their male partners and have long provided quality sexually transmitted infection (STI) care and prevention. Chlamydia, an easily treatable STI that can lead to serious adverse outcomes if untreated, is the most common bacterial STI in the USA, and annual chlamydia screening is recommended for sexually active women aged ≤25 years. As early adopters of routine screening, family planning clinics screen >50% of all care-seeking eligible women for chlamydia, performing better than private sector healthcare plans. To achieve high levels of quality care, family planning clinics have been leaders in implementing evidence-based care delivery and developing prevention innovations. As national healthcare reform is implemented in the USA and categorical STI clinics close, public-sector demand on family planning clinics will increase.
