African-American female adolescents who engage in oral, vaginal and anal sex: "doing it all" as a significant marker for risk of sexually transmitted infection

Individual, partner, and partnership level correlates of anal sex among youth in Baltimore City

Anal sex is an efficient mode of STI transmission and studies indicate that anal sex is common among heterosexuals, including adolescents. We examined the association between individual, partner, and sexual partnership-level characteristics with anal sex among a household survey of 263 individuals aged 15-24 years in Baltimore City, Maryland. We used weighted multiple logistic regression to examine correlates of anal sex in a heterosexual partnership by gender. Twenty-nine percent of males and 15% of females reported anal sex in a partnership in the past 6 months. For males, anal sex was associated with having two or more partners in the past 3 months (AOR = 13.93, 95% CI 3.87-50.12), having been tested for HIV (AOR = 0.30, 95% CI 0.12-0.72), and oral sex with a partner (AOR = 8.79, 95% CI 1.94-39.78). For females, anal sex was associated with reporting having a main partner (AOR = 6.74, 95% CI 1.74-23.65), partner meeting place (AOR = 3.03, 95% CI 1.04-8.82), partner history of STI (AOR = 0.20, 95% CI 0.05-0.85), and oral sex with a partner (AOR = 8.47, 95% CI 1.08-66.25). Anal sex was associated with inconsistent condom use for both males (OR = 5.77, 95% CI 1.68-19.79) and females (OR = 5.16, 95% CI 1.46-18.30). We conclude that anal sex is a prevalent risk behavior among heterosexual youth and is associated with a range of factors at the individual and partnership levels. These findings provide support for comprehensive sex education that includes information about anal sex; findings from this study can inform public health campaigns targeting youth at risk for STIs.

A partner-related risk behavior index to identify people at elevated risk for sexually transmitted infections

The purpose of this study was to develop and test a sexual-partner-related risk behavior index to identify high-risk individuals most likely to have a sexually transmitted infection (STI). Patients from five STI and adolescent medical clinics in three US cities were recruited (N = 928; M age = 29.2 years). Data were collected using audio-computer-assisted self-interviewing. Of seven sexual-partner-related variables, those that were significantly associated with the outcomes were combined into a partner-related risk behavior index. The dependent variables were laboratory-confirmed infection with Chlamydia trachomatis, Neisseria gonorrhoeae, and/or Trichomonas vaginalis. Nearly one-fifth of the sample (169/928; 18.4%) tested positive for an STI. Three of the seven items were significantly associated with having one or more STIs: sex with a newly released prisoner, sex with a person known or suspected of having an STI, and sexual concurrency. In combined form, this three-item index was significantly associated with STI prevalence (p < .001). In the presence of three covariates (gender, race, and age), those classified as being at-risk by the index were 1.8 times more likely than those not classified as such to test positive for an STI (p < .001). Among individuals at risk for STIs, a three-item index predicted testing positive for one or more of three STIs. This index could be used to prioritize and guide intensified clinic-based counseling for high-risk patients of STI and other clinics.

Racial/ethnic differences in patterns of sexual risk behavior and rates of sexually transmitted infections among female young adults

OBJECTIVES

We examined patterns of sexual behavior and risk for sexually transmitted infections (STIs) in young adulthood for Black, Hispanic, and White females.

METHODS

We used a nationally representative sample of 7015 female young adults from wave III of the National Longitudinal Study of Adolescent Health. Sexual risk items assessed behaviors occurring in the previous 6 years and past year to determine classes of sexual risk and links to STIs in young adulthood.

RESULTS

Latent class analysis revealed 3 sexual risk classes for Black and Hispanic youths and 4 sexual risk classes for White youths. The moderate and high risk classes had the highest probabilities of risky sexual partners, inconsistent condom use, and early age of sexual initiation, which significantly increased odds for STIs compared with recent abstainers.

CONCLUSIONS

We found different classes of sexual behavior by race/ethnicity, with Black and Hispanic young women most at risk for STIs in young adulthood. Preventive efforts should target younger adolescents and focus on sexual partner behavior.

Associations between patterns of emerging sexual behavior and young adult reproductive health

CONTEXT

Identifying young adult outcomes associated with adolescent sexual behavior, including patterns of first oral, vaginal and anal sex, is critical to promoting healthy sexual development.

METHODS

Associations between patterns of emerging sexual behavior, defined using latent class analysis, and young adult sexual and reproductive health were examined among 9,441 respondents to Waves 1 (1994-1995), 3 (2001-2002) and 4 (2008) of the National Longitudinal Study of Adolescent Health. Logistic regression analyses examined associations between class membership and young adult outcomes, and tested for interactions by race and ethnicity.

RESULTS

Compared with respondents who initiated vaginal sex first and reported other sexual behaviors within two years, those who initiated oral and vaginal sex during the same year had similar odds of having had an STD diagnosis ever or in the last year, of having had concurrent sexual partnerships in the last year and of having exchanged sex for money. However, respondents who postponed sexual activity had reduced odds of each outcome (odds ratios, 0.2-0.4); those who initiated vaginal sex and reported only one type of sexual behavior had reduced odds of reporting STD diagnoses and concurrent partnerships (0.4-0.6). Respondents who reported early initiation of sexual activity combined with anal sex experience during adolescence had elevated odds of having had concurrent partnerships (1.6). The data suggest racial and ethnic disparities even when patterns of emerging sexual behavior were the same.

CONCLUSIONS

Patterns of early sexual behavior considered high-risk may not predict poor sexual and reproductive health in young adulthood.

Oncogenic HPV Types Infection in Adolescents and University Women from North Portugal: From Self-Sampling to Cancer Prevention

This study aimed to characterize the HPV infection status in adolescents and young university women in Portugal. The distribution of HPV genotypes was evaluated by PCR DNA genotyping after self-sampling collection from 435 women of exfoliated cervical cells using a commercial kit. We observed an overall frequency of HPV infection of 11.5%. Furthermore, HPV DNA prevalence was 16.6% in those young women that self-declared as sexually active. The more frequently detected HPV types were 31, 16, 53, and 61. Statistical analysis identified median age (OR = 3.56; P = 0.001), the number of lifetime sexual partners (OR = 4.50; P < 0.001), and years of sexual activity (OR = 2.36; P = 0.008) as risk factors for HPV acquisition. Hence, our study revealed that oncogenic HPV infection is common in young asymptomatic women Portuguese women, with a history of 2-5 sexual partners and over 2 year of sexual activity. Moreover, these results demonstrate that HPV detection performed in self-collected samples may be important to appraise better preventive strategies and to monitorize the influence of vaccination programmes within different populations.

Unwanted unprotected sex: condom coercion by male partners and self-silencing of condom negotiation among adolescent girls

This exploratory study used the theory of reasoned action and the theory of gender and power to guide elicitation of partner-related impediments to condom use among 64 adolescent girls living in poor urban areas with high rates of HIV and partner abuse. About 53% indicated that they had experienced unwanted, unprotected vaginal sex and 25% indicated that they were unable to discuss condom use with a partner. Novel qualitative findings related to condom coercion, condom sabotage, and self-silencing of condom negotiation are discussed in the context of connecting partner abuse to interpersonal control over condom use. Implications for intervention design are discussed.

Heterosexual anal sex experiences among Puerto Rican and black young adults

CONTEXT

Heterosexual anal sex is not uncommon in the United States, and it poses risk for STDs. However, who engages in it and why are not well understood, particularly among young adults.

METHODS

In 2006-2008, data on sexual health-related topics were collected in surveys (483 respondents) and qualitative interviews (70 participants) with black and Puerto Rican 18-25-year-olds in Hartford and Philadelphia. Bivariate and multivariate analyses of survey data assessed predictors of anal sex with the most recent serious heterosexual partner. Interview transcripts were analyzed for anal sex experiences and reasons for and against engaging in this behavior.

RESULTS

Some 34% of survey respondents had had anal sex; this behavior was more common with serious partners than with casual partners (22% vs. 8%). Black respondents were less likely than Puerto Ricans to report anal sex (odds ratio, 0.3); women were more likely to do so than were men (2.9). In the qualitative cohort, perceptions of anal sex as painful and unappealing were the predominant reasons for not having anal sex, whereas sexual pleasure and, in serious relationships, intimacy were the main reasons for engaging in it. Condom use during anal sex was rare and was motivated by STD or hygiene concerns.

CONCLUSIONS

Heterosexual anal sex is not an infrequent behavior and should be considered in a broad sexual health context, not simply as an indicator of STD risk. Health providers should address it openly and, when appropriate, as a positive sexual and emotional experience.

The State of the union: sexual health disparities in a national sample of US college students

OBJECTIVE

To examine sexual health disparities between blacks and whites in a national sample of US college students. PARTICIPANTS AND METHOD SUMMARY: Analyses utilized secondary data from 44,165 nonmarried undergraduates (aged 18-24; M = 20.1) responding to the Spring 2007 American College Health Association-National College Health Assessment; 64% were female and 94.7% were white.

RESULTS

Whites reported more experience in oral and anal sex, were less likely to use condoms for oral, anal, and vaginal sex, and less likely to have been tested for HIV (human immunodeficiency virus) compared with blacks. However, blacks reported more sex partners, lower use of hormonal contraceptives, and higher rates of adverse sexual health outcomes, such as sexually transmitted infections (STIs) and unintended pregnancy. Sexual behaviors and outcomes also varied across gender.

CONCLUSIONS

This study highlights a need to increase access to hormonal contraceptives and early STI screening/treatment among blacks, improve HIV testing among whites, and increase condom use promotion for all students.
