Article ReferenceGenetic Clustering Analysis for HIV Infection among Men Who Have Sex with Men in Nigeria
Background:  The  HIV  epidemic continues to grow among  MSM  in countries across sub-Saharan Africa including  Nigeria . To inform prevention efforts, we used a  phylogenetic cluster  method to characterize  HIV  genetic clusters and factors associated with cluster formation among  MSM  living with  HIV  in  Nigeria . Methods:  We analyzed  HIV -1 pol sequences from 417  MSM  living with  HIV  enrolled in the TRUST/RV368 cohort between 2013 and 2017 in Abuja and Lagos,  Nigeria . A genetically linked cluster was defined among participants whose sequences had pairwise genetic distance of 1.5% or less. Binary and multinomial logistic regressions were used to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for factors associated with  HIV  genetic cluster membership and size. Results:  Among 417  MSM  living with  HIV , 153 (36.7%) were genetically linked. Participants with higher viral load (AOR = 1.72 95% CI: 1.04–2.86), no female partners (AOR = 3.66; 95% CI: 1.97–6.08), and self-identified as male sex (compared with self-identified as bigender) (AOR = 3.42; 95% CI: 1.08–10.78) had higher odds of being in a genetic cluster. Compared with unlinked participants,  MSM  who had high school education (AOR = 23.84; 95% CI: 2.66–213.49), were employed (AOR = 3.41; 95% CI: 1.89–10.70), had bacterial sexually transmitted infections (AOR = 3.98; 95% CI: 0.89–17.22) and were not taking antiretroviral therapy (AOR = 6.61; 95% CI: 2.25–19.37) had higher odds of being in a large cluster (size > 4). Conclusion:  Comprehensive  HIV  prevention packages should include behavioral and biological components, including early diagnosis and treatment of both  HIV  and bacterial sexually transmitted infections to optimally reduce the risk of  HIV  transmission and acquisition.

Article ReferenceHealth Care Experiences of Black Transgender Women and Men Who Have Sex With Men
Black sexual and gender minorities (SGM) are at greater risk for HIV compared to their White, cisgender, heterosexual counterparts. Linkage to culturally sensitive health care is, therefore, pivotal for HIV prevention and treatment of Black SGM. Unfortunately, social and structural challenges undermine Black SGM individuals' abilities to obtain adequate health care services, indicating a need to understand Black SGM perceptions of health care. To address this gap, we interviewed Black men who have sex with men and transwomen about their experiences with health care providers. Participants discussed needs and concerns, including provider SGM identity diversity and education; assumptions, judgment, stigma, and discrimination; and ability to establish a personal bond, trust, and familiarity. Black SGM indicated that providers often did not meet their needs in different ways regarding their SGM identities. Findings suggest a need for provider cultural sensitivity education programs that address the needs of Black SGM in health care.

The past several decades have witnessed growing geographic disparities in life expectancy within the United States, yet the mortality experience of U.S. cities has received little attention. We examine changes in men’s life expectancy at birth for the 25 largest U.S. cities from 1990 to 2015, using mortality data with city of residence identifiers. We reveal remarkable increases in life expectancy for several U.S. cities. Men’s life expectancy increased by 13.7 years in San Francisco and Washington, DC, and by 11.8 years in New York between 1990 and 2015, during which overall U.S. life expectancy increased by just 4.8 years. A significant fraction of gains in the top-performing cities relative to the U.S. average is explained by reductions in HIV/AIDS and homicide during the 1990s and 2000s. Although black men tended to see larger life expectancy gains than white men in most cities, changes in socioeconomic and racial population composition also contributed to these trends.

Article Reference Troff document (with manpage macros)School punishment and interpersonal exclusion: Rejection, withdrawal, and separation from friends
Abstract School suspension is a common form of punishment in the United States that is disproportionately concentrated among racial minority and disadvantaged youth. In labeling theories, the implication is that such stigmatized sanctions may lead to interpersonal exclusion from normative others and to greater involvement with antisocial peers. I test this implication in the context of rural schools by 1) examining the association between suspension and discontinuity in same-grade friendship ties, focusing on three mechanisms implied in labeling theories: rejection, withdrawal, and physical separation; 2) testing the association between suspension and increased involvement with antisocial peers; and 3) assessing whether these associations are stronger in smaller schools. Consistent with labeling theories, I find suspension associated with greater discontinuity in friendship ties, based on changes in the respondents’ friendship preferences and self-reports of their peers. My findings are also consistent with changes in perceptual measures of exclusion. Additionally, I find suspension associated with greater involvement with substance-using peers. Some but not all of these associations are stronger in smaller rural schools. Given the disproportionate distribution of suspension, my findings indicate that an excessive reliance on this exclusionary form of punishment may foster inequality among these youth.

OBJECTIVE: Research on the heterogeneity in drinking patterns of urban minorities within a socioecological framework is rare. The purpose of this study was to explore multiple, distinct patterns of drinking from adolescence to young adulthood in a sample of urban minority youth and to examine the influence of neighborhood, family, and peers on these trajectories. METHOD: Data are from a longitudinal study of 584 (56% male) primarily Black (87%) youth who were first sampled in childhood based on their residence in low-income neighborhoods in Baltimore City and followed up annually through age 26. Data were analyzed using group-based trajectory modeling and multinomial logistic regression. RESULTS: Modeling revealed six trajectories from ages 14 to 26: abstainer, experimenter, adult increasing, young adult increasing, adolescent limited, and adolescent increasing. Neighborhood disadvantage was a risk factor for drinking regardless of the timing of onset. Perceptions of availability, peer drinking, and parental approval for drinking were risk factors for underage drinking trajectories, whereas parental supervision was a significant protective factor. Positive social activities in neighborhoods was protective against increased drinking, whereas a decline in perceptions of peer drinking was associated with adolescent-limited drinking. CONCLUSIONS: Our findings uniquely highlight the importance of developing interventions involving parents for urban minority youth for whom family is particularly relevant in deterring underage drinking. Perhaps most importantly, our data suggest that interventions that support positive social activities in disadvantaged neighborhoods are protective against adolescent drinking and altering perceptions of peer drinking may reduce adolescent drinking among low-income, urban minority youth.

Article Reference Troff document (with manpage macros)The Coming Divorce Decline
This article analyzes U.S. divorce trends over the past decade and considers their implications for future divorce rates. Modeling women’s odds of divorce from 2008 to 2017 using marital events data from the American Community Survey, I find falling divorce rates with or without adjustment for demographic covariates. Age-specific divorce rates show that the trend is driven by younger women, which is consistent with longer term trends showing uniquely high divorce rates among people born in the Baby Boom period. Finally, I analyze the characteristics of newly married women and estimate the trend in their likelihood of divorcing based on the divorce models. The results show falling divorce risks for more recent marriages. The accumulated evidence thus points toward continued decline in divorce rates. The United States is progressing toward a system in which marriage is rarer and more stable than it was in the past.

OBJECTIVE: Children exposed to institutional rearing often exhibit problems across a broad array of developmental domains. We compared the consequences of long-term, high-quality foster care versus standard institution-based care, which began in early childhood on cardiometabolic and immune markers assessed at the time of adolescence. METHODS: The Bucharest Early Intervention Project is a longitudinal investigation of children institutionalized during early childhood (ages 6 to 30 months at baseline) who were subsequently randomized to either high-quality foster care or continued institutional care. At the age of 16 years, 127 respondents participated in a biomarker collection protocol, including 44 institutionalized children randomly assigned to receive care as usual, 41 institutionalized children randomized to be removed from institutional care and placed in high-quality foster care in infancy, and a control group of 42 demographically matched children raised in biological families. Outcomes included body mass index (BMI), systolic and diastolic blood pressure, C-reactive protein, interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor α, glycosylated hemoglobin A1c, and Epstein-Barr virus antibody titers. RESULTS: Early institutional rearing was not associated with differences in cardiometabolic or immune markers. Randomization to foster care and age of placement into foster care were also unrelated to these markers, with the exception of BMI z-score, where children assigned to care as usual had lower BMI z-scores relative to children assigned to foster care (-0.23 versus 0.08, p = .06), and older age at placement was associated with lower BMI (β = -0.07, p = .03). CONCLUSIONS: The impact of institutional rearing on measures of cardiometabolic health and immune system functioning is either absent or not evident until later in development. These findings provide new insights into the biological embedding of adversity and how it varies developmentally and across regulatory systems and adversity type.

A growing body of sociological research has shown that racial identification is not only fluid, but crucially depends on other individual- and societal-level factors. When such factors are also associated with socioeconomic outcomes such as earnings, estimates of the disadvantage experienced by individuals because of how they identify racially obtained from standard regression models may be biased. We illustrate this potential bias using data from a large-scale survey conducted by the Mexican census bureau. This survey is the first by the government agency since the country’s independence to include a question on black identification. We find evidence of a substantial bias in estimates of racial disadvantage. Results from our initial models treating racial self-identification as an exogenous predictor indicate that black men have higher earnings than non-black men. However, when we use an instrumental variables model that treats racial self-identification as endogenous, that is, as a function of the same unobserved characteristics as individuals’ earnings, we find a significant negative effect of black identification on earnings. While previous studies have acknowledged the endogeneity of race, ours is the first to explicitly model racial self-identification as an endogenous predictor to obtain an unbiased estimate of its effect on individuals’ socioeconomic conditions.

Article Reference Troff document (with manpage macros)The Impact of Community Size, Community Climate, and Victimization on the Physical and Mental Health of SGM Youth
Sexual and gender minority (SGM) youth experience high rates of victimization leading to health disparities. Community size and community climate are associated with health outcomes among SGM youth; however, we lack studies that include them as covariates alongside victimization to understand their collective impact on health. This study utilized minority stress theory to understand how community context shapes experiences of victimization and health among SGM youth. SGM youth in one Midwestern U.S. state completed an online survey ( n = 201) with measures of physical health, mental health, community context, and victimization. Data were analyzed via multiple regression using a path analysis framework. Results indicate that perceived climate was associated with mental, but not physical, health; Community size was unrelated to health outcomes. Victimization mediated the association between community climate and mental health. Findings are discussed in light of current literature and implications for research and practice are shared.
