Few studies have reported on sexually transmitted infections at the US-Mexico border, so the prevalence of Chlamydia trachomatis in this population remains uncertain. This binational project investigated the prevalence of, and risk factors for, C. trachomatis among women along the Arizona, US-Sonora, Mexico border. Women who self-referred for routine gynaecological care were invited to complete an interviewer-administered questionnaire and to undergo a Pap smear, C. trachomatis test, and HPV test. In 2270 women, C. trachomatis prevalence overall was 8.2% as measured by hybrid capture and 2.6% by enzyme immunoassay. Infection was associated with young age, a history of new sexual partner(s) in the previous three months, HPV infection, and proximity of clinic to the international border. Antibiotic use in the previous 30 days was associated with decreased odds of infection. Women in Arizona-Sonora border communities are at increased risk for C. trachomatis infection compared to women attending clinics in non-border locations.
Background: Screening for asymptomatic Chlamydia trachomatis (Ct) among men has not been recommended because feasibility and efficacy are unknown. Check It is a seek-test-treat community-based Ct screening program for African American men who have sex with women and who are 15 to 24 years of age. This is an evaluation of adaptations made to the program aimed at improving index/partner notification and treatment rates. Methods:The original Check It intervention included free testing and treatment, contact tracing performed by a third party, expedited index therapy, and expedited partner therapy via pharmacy pickup. The intervention was adapted after a series of in-depth interviews eliciting information to refine the program. Changes included continuity of testing, notification, and treatment by the same staff; expanded hours; and patient-delivered partner therapy with a medication mail-delivery option. Rates of index male and partner treatment were compared using log-binomial models and generalized estimating equations.Results: Men in the adapted intervention (n = 85) were more likely than men in the original intervention (n = 99) to be contacted (relative risk [RR], 1.14; 95% confidence interval [CI], 1.02-1.27), make a treatment plan (RR, 1.14; 95% CI, 1.01-1.27), and complete treatment (RR, 1.45; 95% CI, 1.20-1.75). Female sexual partners were significantly more likely to complete treatment in postadaptation (n = 153) compared with preadaptation (n = 161; RR, 3.02; 95% CI, 1.81-5.05).Conclusions: Compared with third-party notification and expedited index therapy/expedited partner therapy available by pharmacy pickup only, patient-delivered partner therapy with mail-delivery option, staff available at nontraditional hours, and staff continuity across testing, notification, and treatment significantly improved index and partner treatment completion.
Background: COVID-19 stay-at-home orders enacted in New Orleans, LA on March 16, 2020, may have caused changes in the way young men interacted with sex partners.Methods: An online substudy was conducted (May 21, 2020 to June 9, 2020) among Black men who have sex with women, 18 years and older, and who had previously enrolled in the parent study Check It (May 17, 2017 to March 6, 2020) to assess changes in sexual behavior during the stay-at-home orders.Results: Among 111 participants, from enrollment in Check It to during stay-at-home orders, recent vaginal sex declined from 96.4% to 47.8% (P < 0.0001), reports of multiple female sex partners declined from 45.0% to 14.4% (P < 0.0001), and sexual abstinence increased from 3.6% to 38.7% (P < 0.0001). Among those who did have vaginal sex, condomless sex rates did not change between enrollment in Check It and the substudy (64.5% vs 67.9%, P = 0.68). During stay-at-home orders oral sex, virtual sex, and pornography viewing were 40.5%, 42.3%, and 76.6%, respectively. Some (17.1%) acquired a new sex partner during stay-at-home orders, and 44.1% left their home to meet a partner for sex. Only 27.9% had seen information about safe sex during the pandemic. Income was diminished for 62.2% and 23.4% moved away from New Orleans when stay-at-home orders were enacted.
Background: Check It is a novel, bundled, community-based seek, test, and treat Chlamydia trachomatis (Ct) screening program for 15-to 24-year-old Black men in New Orleans who have sex with women. The program design addressed barriers and facilitators to Ct screening/ treatment by enlisting trusted community partners, incorporating participant input, providing free index/partner expedited treatment, developing relatable marketing materials and an educational Web site, encouraging peer referral, and providing a modest monetary incentive.Methods: Areas of high poverty were identified using census data; ethnographic/key informant interviews identified sites in those areas where the target population congregated. Black youth informed Web site design and social marketing. Content was inspirational/educational/amusing and endorsed recruitment and brand awareness. A community advisory board, participant interviews, community partner feedback, and recruitment staff involvement in the process evaluation helped refine the program in an ongoing manner.Results: During formative stages, 41 key informant/community advisory board members informed program refinement. Community partners provided venue locations (n = 65) and participant referrals. Between May 22, 2017, and February 28, 2020, 1890 men were enrolled (acceptance rate, 96.0%) with Ct infection rate of 10.2%. Overall study treatment was provided to 86.1% (71.4%-90.9%) of participants who tested positive and 28.5% (14.5%-41.5%) of their partners. Findings from in-depth interviews with participants (n = 43) led to increased treatment uptake.Conclusions: C. trachomatis community screening of young Black men was successful through collaboration with trusted community partners, by tailoring implements/marketing with participant input, reducing barriers to treatment, and providing modest monetary incentives. The Check It program can serve as a roadmap for reducing health disparities in this population.
