RESUMO

IMPORTANCE: Long-acting reversible contraception (LARC), specifically intrauterine devices and implants, offers an unprecedented opportunity to reduce unintended pregnancies among adolescents because it is highly effective even with typical use. However, adolescent LARC users may be less likely to use condoms for preventing sexually transmitted infections compared with users of moderately effective contraceptive methods (ie, oral, Depo-Provera injection, patch, and ring contraceptives). OBJECTIVE: To compare condom use between sexually active female LARC users and users of moderately effective contraceptive methods. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional analysis using data from the 2013 national Youth Risk Behavior Survey, a nationally representative sample of US high school students in grades 9 through 12. Descriptive analyses were conducted among sexually active female students (n = 2288); logistic regression analyses were restricted to sexually active female users of LARC and moderately effective contraception (n = 619). The analyses were conducted in July and August 2015. MAIN OUTCOMES AND MEASURES: Contraceptive method at last sexual intercourse was assessed by 1 item-respondents could select birth control pills; condoms; an intrauterine device or implant; injection, patch, or ring; withdrawal or other method; or not sure. A separate item asked whether respondents used a condom at last sexual intercourse. We created an indicator variable to distinguish those reporting use of (1) LARC (intrauterine device or implant), (2) oral contraceptives, and (3) Depo-Provera, patch, or ring. RESULTS: Among the 2288 sexually active female participants (56.7% white; 33.6% in 12th grade), 1.8% used LARC; 5.7% used Depo-Provera, patch, or ring; 22.4% used oral contraceptives; 40.8% used condoms; 11.8% used withdrawal or other method; 15.7% used no contraceptive method; and 1.9% were not sure. In adjusted analyses, LARC users were about 60% less likely to use condoms compared with oral contraceptive users (adjusted prevalence ratio [aPR], 0.42; 95% CI, 0.21-0.84). No significant differences in condom use were observed between LARC users and Depo-Provera injection, patch, or ring users (aPR, 0.57; 95% CI, 0.26-1.25). The LARC users were more than twice as likely to have 2 or more recent sexual partners compared with oral contraceptive users (aPR, 2.61; 95% CI, 1.75-3.90) and Depo-Provera, patch, or ring users (aPR, 2.58; 95% CI, 1.17-5.67). CONCLUSIONS AND RELEVANCE: Observed differences in condom use may reflect motivations to use condoms for backup pregnancy prevention. Users of highly effective LARC methods may no longer perceive a need for condoms even if they have multiple sexual partners, which places them at risk for sexually transmitted infections. As uptake of LARC increases among adolescents, a clear need exists to incorporate messages about condom use specifically for sexually transmitted infection prevention.

RESUMO

Psychosocial stress, including stress resulting from racial discrimination (RD), has been associated with elevated depressive symptoms. However, individuals vary in their reactivity to stress, with some variability resulting from genetic differences. Specifically, genetic variation within the linked promoter region of the serotonin transporter gene (5-HTTLPR) is related to heightened reactivity to emotional environmental cues. Likewise, variations within this region may interact with stressful life events (e.g., discrimination) to influence depressive symptoms, but this has not been empirically examined in prior studies. The objective of this study was to examine whether variation in the 5-HTTLPR gene interacts with RD to predict depressive symptoms among a sample of African-American adolescent females. Participants were 304 African-American adolescent females enrolled in a sexually transmitted disease prevention trial. Participants completed a baseline survey assessing psychosocial factors including RD (low vs. high) and depressive symptomatology (low vs. high) and provided a saliva sample for genotyping the risk polymorphism 5-HTTLPR (s allele present vs. not present). In a logistic regression model adjusting for psychosocial correlates of depressive symptoms, an interaction between RD and 5-HTTLPR group was significantly associated with depressive symptomatology (AOR = 3.79, 95% CI: 1.20-11.98, p = 0.02). Follow-up tests found that high RD was significantly associated with greater odds of high depressive symptoms only for participants with the s allele. RD and 5-HTTLPR status interact to differentially impact depressive symptoms among African-American adolescent females. Efforts to decrease depression among minority youth should include interventions which address RD and strengthen factors (e.g., coping, emotion regulation, building support systems) which protect youth from the psychological costs of discrimination.

RESUMO

UNLABELLED: Background The aim of this study was to describe acceptance of and experiences utilising expedited partner therapy (EPT) among African-American girls recruited from short-term juvenile detention centres. METHODS: Ninety-five detained African-American girls (aged 13-17 years) completed audio computer-assisted self-interviews (ACASI) and self-collected vaginal swab specimens assayed for chlamydia and gonorrhoea. EPT was offered to sexually transmissible infection (STI)-positive participants (n=51); follow-up phone interviews assessed medication delivery to partners. Summary statistics described EPT acceptance frequency. Generalised estimating equations assessed correlates of acceptance. Nine semi-structured interviews elicited EPT experiences. RESULTS: EPT was offered 69 times, accepted by 70% (n=37) girls and provided to 68% (n=36) of girls. Acceptance was significantly associated with sexual risk behaviours such as infrequent partner STI prevention discussion (OR=3.2, 95% CI: 1.0,-10.1, P=0.048) and≥4 lifetime sex partners (OR=3.3, 95% CI: 1.0-11.0, P=0.048). Discontinued relationships were the most common barrier to EPT acceptance. Emergent interview themes included sense of responsibility, which appeared to motivate acceptance and help overcome identified discomfort with partner disclosure conversations. CONCLUSIONS: Future research is needed to determine EPT efficacy among African-American juvenile populations and feasibility of its use outside of research settings.

RESUMO

Heightened psychosocial stress coupled with maladaptive coping may be associated with greater sexual risk engagement. This study examined the association between stress levels and coping strategy use as predictors of sexual risk behavior engagement over 24 months among African-American adolescent females (N = 701; M = 17.6 years) enrolled in an STI/HIV risk-reduction intervention program. Participants completed audio computer assisted self-interview (ACASI) measures of global stress, interpersonal stress, coping strategy use, and sexual behaviors prior to intervention participation. Follow-up ACASI assessments were conducted at 6, 12, 18, and 24 months post-intervention. Generalized estimated equation models examined associations between baseline stress levels and coping strategy use as predictors of condom use (past 90 days, last sex) and multiple partners during follow-up. Global stress and individual coping strategy usage were not associated with differences in condom use. Higher interpersonal stress was associated with lower proportion condom use (p = .018), inconsistent condom use (p = .011), and not using a condom at last sex (p = .002). There were no significant associations between stress levels, coping strategy use, and multiple partners. Future research should explore mechanisms that may underlie the association between elevated interpersonal stress and decreased condom use among this population.

RESUMO

Adolescents experience elevated depressive symptoms which health promotion interventions may reduce. This study investigated whether HIV prevention trial participation decreased depressive symptoms among African-American female adolescents. Adolescents (N = 701; M age = 17.6) first received a group-delivered HIV prevention intervention and then either 12 sexual health (intervention condition) or 12 general health (comparison condition) phone counseling contacts over 24 months. ACASI assessments were conducted at baseline, and at 6-, 12-, 18-, and 24-months post-baseline. Linear generalized estimating equations were used to detect percent relative change in depressive symptoms. Participants reported a 2.7% decrease in depressive symptoms (p = 0.001) at each assessment. Intervention participants endorsed an additional 3.6% decrease in depressive symptoms (p = 0.058). Trial participation was associated with reduced depressive symptomatology, particularly among those receiving personalized sexual health counseling. HIV prevention interventions may benefit from incorporating additional content to address adolescents' mental health needs.

RESUMO

Alcohol use disorders are common among HIV-infected individuals and are associated with adverse physiological complications and increased engagement in other health risk behaviors. This paper provides a review and critique of interventions to reduce alcohol use among HIV-infected individuals, including a: (a) synthesis of core intervention components and trial designs; (b) summary of intervention efficacy to reduce alcohol use outcomes; and (c) methodological critique and guidance for future research. We reviewed 14 behavioral interventions that reported on alcohol use outcomes among HIV-infected individuals. Findings were mixed for intervention efficacy to reduce alcohol frequency and quantity. There was limited evidence that interventions reduced binge drinking frequency or alcohol abuse or dependence symptoms. Despite the prevalence of disordered alcohol use among HIV-infected individuals, there is lack of efficacious intervention approaches. Efficacious intervention approaches to reduce alcohol use among HIV-infected individuals are urgently needed.

RESUMO

BACKGROUND: Without treatment, approximately half of HIV-infected infants die by age 2 years, and 80% die before age 5 years. Early identification of HIV-infected and HIV-exposed infants provides opportunities for life-saving interventions. We evaluated integration of HIV-related services with routine infant immunization in Tanzania. METHODS: During April 2009 to March 2010, at 4 urban and 4 rural sites, mothers' HIV status was determined at first-month immunization using antenatal cards. HIV-exposed infants were offered HIV testing and follow-up care. Impact of integrated service delivery was assessed by comparing average monthly vaccine doses administered during the study period and a 2-year baseline period; acceptance was assessed by interviewing mothers and service providers. FINDINGS: During 7569 visits, 308 HIV-exposed infants were identified and registered; of these, 290 (94%) were tested, 15 (5%) were HIV infected. At urban sites, first-month vaccine doses remained stable (+2% for pentavalent vaccine and -4% for polio vaccine), and vaccine doses given later in life (pentavalent, polio, and measles) increased 12%, 8%, and 11%, respectively. At rural sites, first-month vaccine doses decreased 33% and 35% and vaccine doses given later in life decreased 23%, 28%, and 28%. Mothers and service providers generally favored integrated services; however, HIV-related stigma and inadequate confidentiality controls of HIV testing were identified, particularly at rural sites. INTERPRETATION: Integration of HIV-related services at immunization visits identified HIV-exposed infants, HIV-infected infants, and HIV-infected mothers; however, decreases in vaccine doses administered at rural sites were concerning. HIV-related service integration with immunization visits needs careful monitoring to ensure optimum vaccine delivery.
