Blood Donation, Sexual Practices, and Self-Perceived Risk for HIV in the United States Among Young Adult Men Who Have Sex With Men.

ABSTRACT: OBJECTIVES:In the United States, all men who have sex with men (MSM) were banned from donating blood from 1985 through 2015. In 2016, the guideline was amended such that men who had sexual contact with other men within the previous 12 months could not donate blood. We aimed to identify blood donation practices and their relationship with HIV risk and testing among young adult MSM (YMSM) at risk for having HIV. METHODS:In 2014, we recruited HIV-negative non-Hispanic black, Hispanic, and non-Hispanic white YMSM aged 18-24 from across the United States through social media platforms to complete an online survey. Among these YMSM who previously donated blood, we conducted a secondary analysis examining the relationship between having donated blood within the past 12 months and sexual risk behavior from recent condomless anal intercourse (CAI), HIV testing, and self-perceived risk of having an undiagnosed HIV infection. RESULTS:Of the 2261 YMSM surveyed, 1104 (48.8%) had ever previously donated blood and 305 (13.5%) had donated blood within the past 12 months. Of the 305 blood donors, 50 (16.4%) had ever had CAI before their most recent blood donation. Among YMSM who donated blood, past-12-month blood donation was more likely among YMSM who never had CAI (adjusted odds ratio [aOR] = 1.84; 95% confidence interval [CI], 1.24-2.73) than among YMSM who had CAI and more likely among YMSM who believed it was not possible at all that they had an undiagnosed HIV infection (aOR = 1.57; 95% CI, 1.14-2.16) than among YMSM who believed there was any possibility of having an undiagnosed HIV infection; it was not related to past-12-month HIV testing. CONCLUSIONS:YMSM donated blood frequently, suggesting that the deferral process in place did not prevent YMSM from donating blood. The current donor screening process should be reconsidered if it is to prevent YMSM from donating blood. Future research could identify screening questions that permit YMSM with a low risk of HIV infection to donate blood while maintaining the safety of the blood supply.

Project description:In this paper, we present an overview and descriptive results from one of the first egocentric network studies of men who have sex with men (MSM) from across the United States: the ARTnet study. ARTnet was designed to support prevention research for human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) that are transmitted across partnership networks. ARTnet implemented a population-based egocentric network study design that sampled egos from the target population and asked them to report on the number, attributes, and timing of their sexual partnerships. Such data provide the foundation needed for parameterizing stochastic network models that are used for disease projection and intervention planning. ARTnet collected data online from 2017 to 2019, with a final sample of 4904 participants who reported on 16198 sexual partnerships. The aims of this paper were to characterize the joint distribution of three network parameters needed for modeling: degree distributions, assortative mixing, and partnership age, with heterogeneity by partnership type (main, casual and one-time), demography, and geography. Participants had an average of 1.19 currently active partnerships ("mean degree"), which was higher for casual partnerships (0.74) than main partnerships (0.45). The mean rate of one-time partnership acquisition was 0.16 per week (8.5 partners per year). Main partnerships lasted 272.5 weeks on average, while casual partnerships lasted 133.0 weeks. There was strong but heterogenous assortative mixing by race/ethnicity for all groups. The mean absolute age difference for all partnership types was 9.5 years, with main partners differing by 6.3 years compared to 10.8 years for casual partners. Our analysis suggests that MSM may be at sustained risk for HIV/STI acquisition and transmission through high network degree of sexual partnerships. The ARTnet network study provides a robust and reproducible foundation for understanding the dynamics of HIV/STI epidemiology among U.S. MSM and supporting the implementation science that seeks to address persistent challenges in HIV/STI prevention.

Project description:BackgroundPrevious studies showed a higher incidence of lung cancer among young women than among young men in the United States. Whether this pattern has continued in contemporary birth cohorts and, if so, whether it can be fully explained by sex differences in smoking behaviors are unknown.MethodsWe examined the nationwide population-based incidence of lung cancer according to sex, race or ethnic group, age group (30 to 34, 35 to 39, 40 to 44, 45 to 49, and 50 to 54 years), year of birth (1945 to 1980), and calendar period of diagnosis (1995-1999, 2000-2004, 2005-2009, and 2010-2014), and we calculated female-to-male incidence rate ratios. We also examined the prevalence of cigarette smoking, using data from the National Health Interview Survey from 1970 to 2016.ResultsOver the past two decades, the age-specific incidence of lung cancer has generally decreased among both men and women 30 to 54 years of age in all races and ethnic groups, but the declines among men have been steeper. Consequently, among non-Hispanic whites, the female-to-male incidence rate ratios increased, exceeding 1.0 in the age groups of 30 to 34, 35 to 39, 40 to 44, and 45 to 49 years. For example, the female-to-male incidence rate ratio among whites 40 to 44 years of age increased from 0.88 (95% confidence interval [CI], 0.84 to 0.92) during the 1995-1999 period to 1.17 (95% CI, 1.11 to 1.23) during the 2010-2014 period. The crossover in sex-specific rates occurred among non-Hispanic whites born since 1965. Sex-specific incidence rates converged among non-Hispanic blacks, Hispanics, and non-Hispanic Asians and Pacific Islanders but crossed over from a higher incidence among men to a higher incidence among women only among Hispanics. The prevalence of cigarette smoking among women born since 1965 has approached, but generally not exceeded, the prevalence among men.ConclusionsThe patterns of historically higher incidence rates of lung cancer among men than among women have reversed among non-Hispanic whites and Hispanics born since the mid-1960s, and they are not fully explained by sex differences in smoking behaviors. Future studies are needed to identify reasons for the higher incidence of lung cancer among young women. (Funded by the American Cancer Society.).
