High Human Immunodeficiency Virus Incidence and Prevalence and Associated Factors Among Adolescent Sexual Minority Males-3 Cities, 2015.

Background: Much has been written about the impact of human immunodeficiency virus (HIV) among young (13-24) sexual minority men (SMM). Evidence for concern is substantial for emerging adult (18-24 years) SMM. Data documenting the burden and associated risk factors of HIV among adolescent SMM (<18 years) remain limited. Methods: Adolescent SMM aged 13-18 years were recruited in 3 cities (Chicago, New York City, and Philadelphia) for interview and HIV testing. We used χ2 tests for percentages of binary variables and 1-way analysis of variance for means of continuous variables to assess differences by race/ethnicity in behaviors. We calculated estimated annual HIV incidence density (number of HIV infections per 100 person-years [PY] at risk). We computed Fisher's exact tests to determine differences in HIV prevalence by selected characteristics. Results: Of 415 sexually active adolescent SMM with a valid HIV test result, 25 (6%) had a positive test. Estimated annual HIV incidence density was 3.4/100 PY; incidence density was highest for blacks, followed by Hispanics, then whites (4.1, 3.2, and 1.1/100 PY, respectively). Factors associated with higher HIV prevalence included black race; ≥4 male partners, condomless anal sex, and exchange sex in the past 12 months; and a recent partner who was older, black, HIV-infected, or had ever been in jail or prison (P < .05). Conclusions: HIV-related risk behaviors, prevalence, and estimated incidence density for adolescent SMM were high, especially for minority SMM. Our findings suggest that initiating intervention efforts early may be helpful in combating these trends.

Sexual Orientation and Cervical Cancer Screening Among Cisgender Women.

Importance: Lesbian, gay, and bisexual populations face barriers accessing health care in Chicago, Illinois. Objective: To describe the prevalence of up-to-date cervical cancer screening among lesbian, gay, and bisexual vs heterosexual cisgender women in Chicago. Design, Setting, and Participants: This retrospective, cross-sectional, population-based study of cisgender women residing in Chicago was completed from 2020 to 2022 using data from the Healthy Chicago Survey, which is conducted annually by the Chicago Department of Public Health. Participants included cisgender women aged 25 to 64 years with no history of hysterectomy. Respondents who self-identified as lesbian, gay, or bisexual or other than straight, lesbian, or bisexual were coded as lesbian, gay, or bisexual (LGB). Respondents who self-identified as straight were coded as heterosexual. Those who reported having a Papanicolaou test within the past 3 years were considered up-to-date with cervical cancer screening. Data analysis was performed from June to October 2023. Exposures: The primary exposure was sexual orientation. Covariates included age, income level, race, ethnicity, having a primary care practitioner (PCP), and insurance coverage. Main Outcomes and Measures: Prevalence ratios (PRs), log-based regression models, and interaction analysis were used to describe the association of sexual orientation with up-to-date screening. Results: The sample included 5167 cisgender women (447 LGB and 4720 heterosexual), aged 25 to 64 years, with no history of hysterectomy. Among LGB cisgender women, 318 (71.14%) reported previous cervical cancer screening compared with 3632 (76.95%) heterosexual cisgender women. The prevalence of up-to-date screening was 10% lower in the LGB group compared with the heterosexual group (PR, 0.90; 95% CI, 0.82-1.00). In regression analysis, having a PCP (PR, 1.43; 95% CI, 1.29-1.59) was associated with up-to-date screening. In interaction analysis, LGB cisgender women with a PCP were 93% more likely to be up-to-date compared with those without a PCP (PR, 1.93; 95% CI, 1.37-2.72). Conclusions and Relevance: In this cross-sectional study of cervical cancer screening rates between the heterosexual and LGB populations in Chicago, up-to-date cervical cancer screening was associated with having a PCP, regardless of sexual orientation, but this association was greater for LGB individuals. Although LGB populations were less likely to be screened, this disparity may be reduced with more consistent health care access and established care with PCPs.

Estimating the number of young Black men who have sex with men (YBMSM) on the south side of Chicago: towards HIV elimination within US urban communities.

The rate of HIV infection among young Black men who have sex with men (YBMSM) aged 16-29 is increasing significantly in the United States. Prevention in this population would considerably impact future health-care resources given the need for lifelong antiretrovirals. A YBMSM population estimate is needed to assist HIV prevention program planning. This analysis estimates the number of YBMSM aged 16-29 living on the south side of Chicago (SSC), the Chicago HIV epicenter, as the first step in eliminating HIV in this population. Three methods were utilized to estimate the number of YBMSM in the SSC. First, an indirect approach following the formula a = k/b; where a = the estimated number of YBMSM, k = the average YBMSM HIV prevalence estimate, and b = the YBMSM population-based HIV seropositivity rate. Second, data from the most recent National Survey of Family Growth (NSFG) was used to estimate the proportion of Black men who report having sex with a man. Third, a modified Delphi approach was used, which averaged community expert estimates. The indirect approach yielded an average estimate of 11.7 % YBMSM, the NSFG yielded a 4.2 % (95 % CI 2.28-6.21) estimate, and the modified Delphi approach yielded estimates of 3.0 % (2.3-3.6), 16.8 % (14.5-19.1), and 25 % (22.0-27.0); an average of 14.9 %. The crude average of the three methods was 10.2 %. Applied to SSC, this results to 5,578 YBMSM. The estimate of 5,578 YBMSM represents a group that can be feasibly reached with HIV prevention efforts. Population estimates of those most at risk for HIV will help public health officials allocate resources, offering potential for elimination of new HIV cases.

Family Factors and HIV-Related Risk Behaviors Among Adolescent Sexual Minority Males in Three United States Cities, 2015.

Purpose: We examined the relationship between family factors and HIV-related sexual risk behaviors among adolescent sexual minority males (ASMM) who are affected disproportionately by HIV. Methods: We analyzed results from the National HIV Behavioral Surveillance among Young Men Who Have Sex with Men. Adolescent males ages 13-18 who identified as gay or bisexual, or who reported attraction to or sex with males were interviewed in 2015 in Chicago, New York City, and Philadelphia. Separate log-linked Poisson regression models were used to estimate associations between family factors and sexual risk behaviors. Results: Of the 569 ASMM, 41% had condomless anal intercourse in the past 12 months, 38% had ≥4 male sex partners in the past 12 months, and 23% had vaginal or anal sex before age 13. ASMM who had ever been kicked out of their house or run away, those who were out to their mother, and those who were out to their father, were more likely to engage in sexual risk behaviors. ASMM who were currently living with parents or guardians and those who received a positive reaction to their outness by their mother were less likely to engage in sexual risk behaviors. Conclusion: Our findings highlight the important role of family factors in HIV risk reduction among ASMM. A better understanding of the complex dynamics of these families will help in developing family-based interventions.

Latent Classes of Sexual Risk Behavior and Engagement in Outreach, Intervention and Prevention Services Among Women Who Inject Drugs Across 20 US Cities.

BACKGROUND: Monitoring the effects of HIV prevention efforts among persons who inject drugs is key to informing prevention programs and policy. METHODS: Data for this study came from the 2012 National HIV Behavioral Surveillance interviews with persons who inject drugs across 20 US cities. The present analyses include those who identified as female, ever had sex with a man, and were at risk of HIV infection (did not report a previous positive HIV test result) (n = 2624). We conducted latent class analysis to identify sexual risk classes, and modeled associations with engagement in HIV prevention services and HIV test results. RESULTS: We identified 6 classes of sexual risk behavior: (1) low risk, (2) monogamous, (3) casual partner, (4) multiple partners, (5) exchange sex, and (6) exchange plus main partner. The class distribution was similar across the mainland regions. Bisexual orientation and homelessness were significant predictors of higher-risk class. HIV prevalence and participation in behavioral interventions did not vary significantly by risk class, while obtaining and using free condoms did. Independent of risk class, women in cities in the South were significantly less likely to use free condoms, and HIV prevalence was higher among non-Hispanic black women and women aged 40-49 years. CONCLUSIONS: Bisexual orientation and homelessness were predictors of higher risk. Condom distribution programs reached fewer women in cities in the South. Race and age disparities in HIV-positive rates persisted after adjusting for sexual risk class.

Preterm birth among African American and white women with a lifelong residence in high-income Chicago neighborhoods: an exploratory study.

OBJECTIVE: To explore the association between race and preterm birth among women with a lifelong residence in high-income neighborhoods. METHODS: Stratified and multivariable logistic regression analyses were performed on the Illinois transgenerational birthfile (infants born 1989-1991 and mothers born 1956-1975) with appended US Census income data. African American (n = 777) and non-Hispanic White (n = 2,327) infants born to mothers with a lifelong residence in Chicago census tracts with median family incomes in the top income quartile were studied. RESULTS: African Americans had a twofold greater preterm (< 37 weeks) birth rate than Whites: 11.6% vs 5.2%, relative risk (95% confidence interval) equaled 2.2 (1.7-2.9). The adjusted (controlling for maternal birth weight, age, education, marital status, cigarette smoking, and prenatal care utilization) odds ratio of preterm birth for African Americans (compared to Whites) equaled 1.2 (.4-2.0). African Americans had a sixfold greater very low birth weight rate (< 1500 g) than Whites: 3.3% vs .6%: relative risk (95% confidence interval) equaled 5.9 (3.1-11.2). The adjusted odds ratio of very low birth weight for African Americans (compared to Whites) equaled 2.4 (1.1-3.9). CONCLUSIONS: A stark racial disparity in the unadjusted rates of preterm birth and very low birth weight exists among women with a lifelong residence in high-income urban neighborhoods; however, the disparity narrows when traditional, individual-level risk factors are mathematically controlled.

Assessing the use of HIV surveillance data to help gauge patient retention-in-care.

BACKGROUND: Improved retention-in-care may enhance health outcomes for people living with HIV/AIDS (PLWHA). Although laboratory surveillance data may be used to gauge retention, no previous reports have compared laboratory surveillance vs. clinic visit-based measures of retention-in-care. We compared laboratory surveillance vs. clinic visit-based approaches for identifying retention status for PLWHA. METHODS: We examined 2011 patient visit data from the Ruth M. Rothstein CORE Center, Cook County's HIV clinic. We defined retained patients as those with visits every 6 months over 2 years and matched patients classified through visit data against HIV surveillance laboratories reported to the Chicago Department of Health. We determined the sensitivity, specificity, and receiver operator characteristics of varying laboratory surveillance vs. clinic visit measures of retention. RESULTS: Of patients classified through clinic visit data, 91% of 1714 in-care vs. 22% of 200 out-of-care patients met our most stringent surveillance-based retention definition-having ≥2 viral load/CD4s performed 90 days apart reported by the same laboratory in 2011. Of surveillance laboratory-based definitions for retention, having ≥2 HIV viral load and/or CD4 values at least 3 months apart reported from the same facility possessed the best receiver operator parameters and the receiver operator characteristics' curve comparing several laboratory surveillance vs. clinic visit-based retention measures that had an area under the curve of 0.95. CONCLUSIONS: Our findings demonstrate that surveillance laboratory data can be used to assess retention-in-care for PLWHA. These data suggest that bi-directional data sharing between public health entities and care providers could advance re-engagement efforts.

Anal intercourse and HIV risk among low-income heterosexual women: findings from Chicago HIV behavioral surveillance.

BACKGROUND: Anal intercourse (AI) is a highly efficient route for HIV transmission and has not been well elucidated among heterosexual (HET) women. Heterosexual women living in impoverished urban areas in the US are at increased risk for HIV acquisition. We aim to describe rates of AI and characteristics associated with AI among heterosexual women at increased risk for HIV acquisition living in Chicago. METHODS: The Chicago Department of Public Health conducted a survey of HET during 2007 as part of the National HIV Behavioral Surveillance System. Venue-based, time-location sampling was used to select participants from venues in high-risk areas (census tracts with concurrently high rates of heterosexual AIDS and household poverty). Eligible participants were interviewed anonymously and offered a HIV test. RESULTS: In total, 407 heterosexual women were interviewed. Seventy-one (17%) women reported having AI in the past 12 months, with 61 of the 71 (86%) reporting unprotected AI. In multivariate analysis, women who engaged in AI were more than three times as likely to have three or more sex partners in the past 12 months (OR=3.27, 95% CI 1.53-6.99). AI was also independently associated with STI diagnosis in the past 12 months (2.13, 95% CI 1.06-4.26), and having sexual intercourse for the first time before the age of 15 years (2.23, 95% CI 1.28-3.89). CONCLUSION: AI was associated with multiple high risk behaviors including a greater number of sexual partners, STI diagnosis, and earlier age at first sex. The combination of risk factors found to be associated with AI call for new HIV prevention services tailored to the needs of women and young girls living in poverty.

Relation of maternal low birth weight to infant growth retardation and prematurity.

OBJECTIVES: This study sought to determine the relationship between maternal birth weight, infant intrauterine growth retardation, and prematurity. METHODS: Stratified and logistic regression analyses were performed on a dataset of computerized Illinois vital records of African American (N = 61,849) and White (N = 203,698) infants born between 1989 and 1991 and their mothers born between 1956 and 1975. RESULTS: Race-specific rates of small-for-gestational age (weight-for-gestational age <10th percentile) and preterm (<37 weeks) infants rose as maternal birth weight declined. The adjusted (controlling for maternal age, education, marital status, parity, prenatal care utilization, and cigarette smoking) odds ratio (95% confidence interval) of small-for-gestational age for maternal low birth weight (<2,500 g) among African Americans and Whites were 1.7 (1.1.4-1.9) and 1.8 (1.7-2.0), respectively. The adjusted odds ratio (95% confidence interval) of prematurity for maternal low birth weight (<2,500 g) among African Americans and Whites were 1.6 (1.3-1.9) and 1.3 (1.0-1.6), respectively. The racial disparity in the rates of small-for-gestational age and prematurity persisted independent of maternal birth weight: adjusted odds ratio equaled 2.2 (2.1-2.4) and 1.5 (1.4-1.7), respectively. CONCLUSIONS: Maternal low birth weight is a risk factor for infant intrauterine growth retardation and prematurity among African Americans independent of maternal risk status during pregnancy; it is a risk factor for infant intrauterine growth retardation among Whites. Maternal low birth weight fails to explain the racial disparity in the rates of small-for-gestational age and premature infants.

Low birth weight across generations.

OBJECTIVES: This study sought to determine the relationship between maternal birth weight, prenatal care usage, and infant birth weight. METHODS: Stratified and logistic regression analyses were performed on a dataset of computerized Illinois vital records of White (N = 187, 074) and African-American (N = 58,856) infants born between 1989 and 1991 and their mothers born between 1956 and 1975. RESULTS: Among White mothers who received adequate prenatal care, the low birth weight (<2500 g) rate was 4% for infants of former low birth weight mothers (N = 5230) compared to 2.1% for infants of former nonlow birth weight mothers (N = 93,011), relative risk equaled 1.9(1.7-2.2); the population attributable risk of maternal low birth weight was 4.1%. Among African American mothers who received adequate prenatal care, the low birth weight rate was 15% for infants of former low birth weight mothers (N = 2196) compared to 7.2% for infants of former nonlow birth weight mothers (N = 14,607), relative risk equaled 2.1(1.9-2.4); the population attributable risk of maternal low birth weight was 10.9%. The maternal-infant birth weight associations were consistent across all maternal age, education, marital status, and prenatal care categories. CONCLUSIONS: Maternal low birth weight is a risk factor for infant low birth weight independent of risk status during the current pregnancy. A greater percentage of low birth weight African American (compared to White) infants are attributable to maternal low birth weight.
