The COVID-19 pandemic has exacerbated prevalence of alcohol use and violence, including gender-based violence (GBV); however, little is understood about the pandemic's impact on the relationship between the two. Data were collected from January 2021-April 2023 with adults who drink alcohol (N = 565) in the San Francisco Bay Area. Questions assessed prevalence of heavy alcohol use (≥4 drinks on one occasion ≥4 times a month) in the past 3 months and violence/GBV exposure before and during the pandemic.

Background: The introduction of antiretroviral therapy (ART) has significantly improved the life expectancy of people living with HIV (PLHIV), leading to an increased prevalence of age-related comorbidities such as osteoporosis. This study investigates the incidence and characteristics of low bone mineral density (BMD) and the treatment effectiveness of low BMD participants among PLHIV in Kerman, Iran.

Methods: A longitudinal study utilized dual-energy X-ray absorptiometry (DEXA) to screen 94 PLHIV in Kerman, Iran, for low BMD.

During the COVID-19 pandemic, the sampling method for the National HIV Behavioral Surveillance (NHBS) in San Francisco changed from physical venue time-location sampling (TLS) to online or virtual venue TLS for men who have sex with men (MSM). We present differences in the samples of MSM recruited using physical venue TLS in 2017 and virtual venue TLS in 2021. We further assess changes in preventive and risk behaviors from 2017 to 2021 after controlling for differences in the sample compositions with multivariable Poisson models using GLM with robust standard errors.
