Black Men Who Have Sex with Men and Lifetime HIV Testing: Characterizing the Reasons and Consequences of Having Never Tested for HIV

Abstract

HIV testing remains a critical point of entry to HIV treatment services and now biomedical prevention as well. Yet despite the high HIV prevalence among Black men who have sex with men (MSM), insufficient attention has been given to factors associated with those Black MSM in the United States who have never received an HIV test in their lifetime. Promoting Our Worth, Equality, & Resilience (POWER) is a cross-sectional observational study that recruited Black MSM at Black Pride events across six cities in the United States from 2014 to 2017. Participants completed an anonymous questionnaire and were offered free, confidential HIV testing. Of the 4174 Black MSM without a prior HIV diagnosis, 404 (9.68%) had never tested for HIV (mean age = 31.03 years). Lower education and greater internalized homophobia were associated with never having tested for HIV. Higher age (AOR = 1.05, 95%, 1.02–1.07) and assumption of HIV-positivity (AOR = 3.24, 95% CI 1.53–6.84) were both associated with increased odds of an HIV-positive test result (n = 119; 36%). To compare, HIV prevalence among Black MSM who had received at least one HIV test before study participation was 23%. While a minority of Black MSM had never received an HIV test, this group had a significantly higher likelihood of HIV infection. Alternative HIV testing strategies are needed to facilitate HIV testing initiation among Black MSM for whom conventional HIV testing modalities are insufficient.

Long-Term Effects of Truancy Diversion on School Attendance: a Quasi-Experimental Study with Linked Administrative Data

Abstract

Over 60% of US school districts implement court diversion programs to address chronic unexcused absenteeism, yet the effectiveness of these programs is not known. We evaluated whether the Truancy Intervention Program (TIP) improved the school attendance of students in grades 7–10 in a metropolitan county in the Midwestern USA. Similar to most truancy court diversion programs, TIP consisted of three increasingly intrusive steps: (1) a parent meeting, (2) a hearing to develop an attendance contract, and (3) a petition to juvenile court. The intervention group consisted of students from the intervention county who had been referred to TIP between 2006 and 2009. The comparison group was drawn from a contiguous, same-sized, and socio-demographically similar county that petitioned truant students directly to court. To construct the comparison group, we applied multi-level matching procedures to linked, individual-level administrative data from eight state and local agencies for all public school students in the state between 2004 and 2015. Using the matched samples, we conducted difference-in-differences analyses to identify program effects for two intervention groups: all students referred to TIP and students whose family participated in the group parent meeting. In the 4 years after the intervention, the intervention groups had similar or slightly lower attendance than the comparison groups. However, most coefficients were not statistically significant, and there was no consistent pattern of effects across different samples and different specifications of the intervention. This pattern of findings was not robust enough to conclude that the program influenced school attendance.

Effectiveness of Potential Interventions to Change Gendered Social Norms on Prevalence of Intimate Partner Violence in Uganda: a Causal Inference Approach

Abstract

Evidence of the effectiveness of programs to change gendered social norms related to intimate partner violence (IPV) is growing, but their potential to significantly impact actual occurrence of IPV at population level is lacking. We study whether modest changes in gendered social norms related to wife-beating can result in significant changes in the incidence of emotional, physical, and sexual IPV among ever married women in Uganda. We employ an imputation-based causal inference approach, based on nationally representative Demographic Health Survey data. The steps are (1) model the association between adjusted neighborhood norms and experiences of IPV using a random effects logistic regression model, (2) impute unobserved counterfactual probabilities of experiencing IPV for each woman while manipulating her neighborhood norms by setting it to different values, (3) average the probabilities across the population, and (4) bootstrap confidence intervals. Results show that statistically significant inverse associations between more prohibitive neighborhood IPV norms and women’s experiences of different forms of IPV at the population level exist. The effect is however small, that even if an entire community disapproves of wife-beating, incidence of IPV falls by about 10 percentage points to 48.5% (95% CI 46.0%–50.9%) from the observed value of 57.6% (95% CI 55.2%–59.9%). Furthermore, changes in neighborhood social norms are found to have no statistical significant effect on the incidence of sexual violence. In conclusion, changing gendered social norms related to wife-beating will not result in significant reductions in different forms for IPV at the population level.

Income Inequality, HIV Stigma, and Preventing HIV Disease Progression in Rural Communities

Abstract

Antiretroviral therapies (ART) suppress HIV replication, thereby preventing HIV disease progression and potentially preventing HIV transmission. However, there remain significant health disparities among people living with HIV, particularly for women living in impoverished rural areas. A significant contributing factor to HIV-related disparities is a stigma. And yet, the relative contributions of stigma, gender, socio-economics, and geography in relation to health outcomes are understudied. We examined the associations of internalized stigma and enacted stigma with community-level income inequality and HIV viral suppression—the hallmark of successful ART—among 124 men and 74 women receiving care from a publicly funded HIV clinic serving rural areas with high-HIV prevalence in the southeastern US. Participants provided informed consent, completed computerized interviews, and provided access to their medical records. Gini index was collected at the census tract level to estimate community-level income inequality. Individual-level and multilevel models controlled for point distance that patients lived from the clinic and quality of life, and included participant gender as a moderator. We found that for women, income inequality, internalized stigma, and enacted stigma were significantly associated with HIV suppression. For men, there were no significant associations between viral suppression and model variables. The null findings for men are consistent with gender-based health disparities and suggest the need for gender-tailored prevention interventions to improve the health of people living with HIV in rural areas. Results confirm and help to explain previous research on the impact of HIV stigma and income inequality among people living with HIV in rural settings.

Addressing the Adherence-Adaptation Debate: Lessons from the Replication of an Evidence-Based Sexual Health Program in School Settings

Abstract

Whether high adherence to programs is necessary to achieve program outcomes is an area of great debate. The objectives of this study were to determine the frequency, type, and rationale of adaptations made in the implementation of an evidence-based program and to determine program outcomes for intervention program participants, as compared to comparison participants, by the level of adaptations. A total of 1608 participants in 45 classrooms participated. Percent adaptations was calculated by classroom. Thematic qualitative analysis was used to categorize types and rationales for adaptations. Program outcomes by level of adaptations were determined using logistic regression analyses and mean differences. Propensity score matching methods were used to create comparability between adaptation subgroup participants and comparison participants. Adaptations ranged from 2 to 97% across classrooms, with mean adaptations of 63%. Thematic analysis revealed that the adaptations made were related to delivery of content, rather than to the content itself and in response to participant needs and setting constraints. Program outcomes did not appear to be reduced for the high-adaptation subgroup. Understanding both rationale (intent) and type of adaptation made is crucial to understanding the complexity of adaptations. These finding support the argument for allowing facilitators some flexibility and autonomy to adapt the delivery of prescribed content to participant needs and setting constraints.

Predictive Association of Smoking with Depressive Symptoms: a Longitudinal Study of Adolescent Twins

Abstract

Longitudinal, genetically informative studies of the association between cigarette smoking and depressive symptoms among adolescents are limited. We examined the longitudinal association of cigarette smoking with subsequent depressive symptoms during adolescence in a Finnish twin cohort. We used prospective data from the population-based FinnTwin12 study (maximum N = 4152 individuals, 1910 twin pairs). Current smoking status and a number of lifetime cigarettes smoked were assessed at the age of 14 and depressive symptoms at the age of 17. Negative binomial regression was conducted to model the association between smoking behavior and subsequent depressive symptoms among individuals, and within-pair analyses were conducted to control for unmeasured familial confounding. Analyses were adjusted for age, sex, school grades, drinking alcohol to intoxication, health status, family structure, parental education, and smoking, as well as for pre-existing depressiveness. The results of the individual-level analyses showed that cigarette smoking at the age of 14 predicted depressive symptoms at the age of 17. Compared to never smokers, those who had smoked over 50 cigarettes (incidence rate ratio, IRR = 1.43, 95% CI 1.28–1.60) and regular smokers (IRR = 1.46, 95% CI 1.32–1.62) had higher depression scores. The associations were attenuated when adjusted for measured covariates and further reduced in within-pair analyses. In the within-pair results, the estimates were lower within monozygotic (MZ) pairs compared to dizygotic (DZ) pairs, suggesting that shared genetic factors contribute to the associations observed in individual-based analyses. Thus, we conclude that cigarette smoking is associated with subsequent depressive symptoms during adolescence, but the association is not independent of measured confounding factors and shared genetic influences.

Effects of Social Development Intervention in Childhood on Adult Life at Ages 30 to 39

Abstract

Elementary schools can be effective sites for universal preventive interventions. Less is known about how long effects of intervention in elementary grades last. Can they improve outcomes in adulthood? To test effects of a social developmental intervention in the elementary grades on adult life through the 30s, the Seattle Social Development Project, a nonrandomized controlled trial, followed all consenting 5th-grade students (N = 808) from 18 Seattle public elementary schools from age 10 (in 1985) to age 39 (in 2014), with 88% retention. The sample was gender balanced and ethnically and economically diverse. The full intervention, called Raising Healthy Children, continued from Grades 1 through 6 and consisted of teacher in-service training in classroom management and instructional methods; cognitive, social, and refusal skills training for children; and parent workshops in child behavior monitoring and management, academic support, and anticipatory guidance. Using structural equation modeling, we examined intervention effects from age 30 to age 39 across 9 constructs indicating 3 domains of adult life: health behavior, positive functioning, and adult health and success. An omnibus test across all 9 constructs indicated a significant positive overall intervention-control difference. Examined individually, significant intervention effects included better health maintenance behavior, mental health, and overall adult health and success. Significant effects were not found on substance use disorder symptoms, sex-risk behaviors, or healthy close relationships in the 30s. Results indicate that sustained, theory-based, multicomponent intervention in the elementary grades can produce lasting changes in health maintenance, mental health, and adult functioning through the 30s.

Mind the Gap: Bridging the Divide Between Current Binge Drinking Prevention and the Needs of Hispanic Underage Emerging Adults

Abstract

In this article, we highlight the urgent public health need for prevention of heavy episodic drinking among underage Hispanic emerging adults in the USA. We outline the current state of binge drinking prevention programming and contrast it with the unique cultural, social, and developmental realities of this population using an ecodevelopmental framework (Szapocznik and Coatsworth 1999). Finally, we advance specific recommendations for the development and delivery of culturally tailored, multisystemic binge drinking prevention programs for underage Hispanic emerging adults.

Differential Consequences: Racial/Ethnic and Gender Differences in the Enduring Impact of Early Disadvantage on Heavy Drinking in Midlife

Abstract

We use a “chain of risks” model to identify risk factors for prolonged heavy drinking in a nationally representative US sample followed from adolescence to middle age, focusing on educational mediators and differential consequences of early exposure to family poverty and area-level disadvantage. Using data from the 1979 National Longitudinal Survey of Youth (civilian respondents ages 14–19 at baseline, N = 5781), longitudinal path models assessed racial/ethnic and gender differences in indirect effects of early disadvantage (duration of exposure to family poverty and area-level disadvantage during adolescence) on midlife heavy drinking. Educational mediators were high school academic performance (taking remedial coursework), high school completion, and attaining a college education. Subgroups were based on race/ethnicity (50.7% White, 30.5% Black, 18.8% Hispanic respondents) and gender (49.6% males). There was a significant indirect path from family poverty during adolescence to poor high school academic performance, lower educational attainment, and more heavy drinking in midlife. For Black respondents, there was an additional direct effect of early area-level disadvantage on greater midlife heavy drinking that was not seen for other groups. The effect of family poverty on reduced high school graduation was stronger for males than females. Enduring impacts of family poverty duration during adolescence on educational attainment have consequences for health risk behaviors in midlife. Due to differential exposure to early adversity, intersectoral interventions are needed to reduce disparities in alcohol outcomes and to promote health equity among high-risk populations.

Patterns of Family, School, and Community Promotive Factors and Health Disparities Among Youth: Implications for Prevention Science

Abstract

Increasing knowledge of factors that promote health among youth from diverse backgrounds is an important step towards addressing health disparities. Although many promotive factors have been identified individually, there is an overabundance of research on risk factors, and a comparable dearth of knowledge regarding the influence of combinations of promotive factors. The current study examined how promotive factors across family, school, and community contexts co-occur to promote health among youth of different race/ethnicity. Utilizing a nationally representative sample of Black (10%), Latinx (12%), and White (77%) youth ages 12–17 (N = 30,668), latent class analysis was employed to identify classes of youth who endorsed homogenous patterns of promotive factors. Associations between class membership and health were explored. Each subsample was best characterized by its own 4-class model, with significant differences in patterns of promotive factors experienced by Black, Latinx, and White youth. Youth health outcomes also varied significantly by class membership (p < .05). Greater access to more promotive factors was associated with better health, and low access to community and school promotive factors was associated with worse health. Results suggest that increasing promotive factors in school, family, and community settings may help to prevent poor health outcomes; however, jointly addressing discrimination against racial/ethnic minority youth through education, policy, and practice is also needed to address health disparities.
