Young men who have sex with men (MSM) of color are at increased risk for HIV infection. Mpowerment (MP) is an intervention designed to reduce risky sexual behavior and increase HIV testing among young MSM ages 18–29. From 2009 to 2012, three community-based organizations with support from the U.S. Centers for Disease Control and Prevention evaluated MP among N = 298 participants. Following a repeated measures design, data from 3- and 6-month follow-ups were compared to baseline. HIV testing and self-efficacy for safer sex increased at both follow-up time points; self-acceptance as an MSM was higher at follow-up 2. Condomless anal/ vaginal sex was lower at follow-up 1 only. Frequency of exchange of safer sex messages among gay/bisexual/transgender friends was lower at follow-up 1, but similar to baseline at follow-up 2. Exposure to MP was associated with improved perceived positive social norms about safer sex and safer sex messages among gay/bisexual/transgender friends. © 2017 The Guilford Press.

Objectives: To describe the extent to which Centers for Disease Control and Prevention (CDC)-funded HIV testing in nonhealthcare facilities reaches adolescent MSM, identifies new HIV infections, and links those newly diagnosed to medical care. Methods/design: We describe HIV testing, newly diagnosed positivity, and linkage to medical care for adolescent MSM who received a CDC-funded HIV test in a nonhealthcare facility in 2015. We assess outcomes by race/ethnicity, HIV-related risk behaviors, and US geographical region. Results: Of the 703 890 CDC-funded HIV testing events conducted in nonhealthcare facilities in 2015, 6848 (0.9%) were provided to adolescent MSM aged 13-19 years. Among those tested, 1.8% were newly diagnosed with HIV, compared with 0.7% among total tests provided in nonhealthcare facilities regardless of age and sex. The odds of testing positive among black adolescent MSM were nearly four times that of white adolescent MSM in multivariable analysis (odds ratio = 3.97, P < 0.001). Among adolescent MSM newly diagnosed with HIV, 67% were linked to HIV medical care. Linkage was lower among black (59%) and Hispanic/Latino adolescent MSM (71%) compared with white adolescent MSM (88%). Conclusion: CDC-funded nonhealthcare facilities can reach and provide HIV tests to adolescent MSM and identify new HIV infections; however, given the low rate of HIV testing overall and high engagement in HIV-related risk behaviors, there are opportunities to increase access to HIV testing and linkage to care for HIV-positive adolescent MSM. Efforts are needed to identify and address the barriers that prevent black and Hispanic/Latino adolescent MSM from being linked to HIV medical care in a timely manner. Copyright © 2017 The Author(s).

BACKGROUND: School closure is one of the primary measures considered during severe influenza pandemics and other emergencies. However, prolonged school closures may cause unintended adverse consequences to schools, students, and their families. A better understanding of these consequences will inform prepandemic planning, and help public health and education authorities in making informed decisions when considering school closures. METHODS: We conducted a household survey and interviewed school officials following an 8-day long closure of a school district in rural Illinois. We described household responses regarding difficulties of school closure, and summarized main themes from school official interviews. RESULTS: A total of 208 (27%) household surveys were completed and returned. This school closure caused difficulties to 36 (17%) households; uncertain duration of closure, childcare arrangements, and lost pay were the most often reported difficulties. Having 1 adult in the household losing pay and household income below $25,000 were significantly associated with overall difficulty during this school closure. Concern about student health and safety was the most frequent theme in school administrator interviews. CONCLUSIONS: Whereas the majority of responding households did not report difficulties during this school closure, households with 1 adult losing pay during the closure reported incurring additional expenses for childcare.
