Purpose: To compare the role of neighborhood social disorganization factors on human immunodeficiency virus (HIV) diagnosis rates in urban and rural areas in Florida, we conducted an ecologic study of HIV diagnosis rates during 2013-2017 and social disorganization components, including concentrated disadvantage, ethnic heterogeneity, and residential instability.

Methods: Indices of social disorganization components were obtained from principal component analyses of American Community Survey variables for 910 postal codes. Rural/urban classification was based on the United States Department of Agriculture Rural Urban Commuting Area codes.

Identifying patterns of retention in care and viral suppression using latent class analysis among women living with HIV in Florida 2015-2017.

The study objective was to classify women with newly diagnosed HIV into patterns of retention in care (≥2 HIV care visits ≥3 months apart) and viral suppression over time and identify factors associated with class membership. Florida HIV/AIDS surveillance data were used to conduct Latent Class Analysis to classify women into patterns, and multinomial regression was used to compare the prevalence of class membership by demographic and clinical factors. Four classes were selected based on model fit parameters: (Class 1) consistently retained and suppressed (>90% probability of being retained and suppressed), (Class 2) not consistently retained or suppressed (≤10% probability of being retained and suppressed), (Class 3) increasingly retained and suppressed, and (Class 4) decreasingly retained and suppressed.

Estimating the size of HIV-negative MSM population that would benefit from pre-exposure prophylaxis in Florida.

Purpose: This study aimed to estimate the size of the population of men who have sex with men (MSM) in Florida with high-risk behaviors that would indicate eligibility for pre-exposure prophylaxis (PrEP) use.

Methods: Three methods were used to estimate the MSM population. Estimates from the three methods were averaged, and the number of MSM living with HIV in each zone improvement plan (ZIP) code was subtracted.

Individual and neighborhood predictors of retention in care and viral suppression among Florida youth (aged 13-24) living with HIV in 2015.

Youth aged 13‒24, are less likely to be retained in HIV care and be virally suppressed than older age groups.
