Association of In Utero HIV Exposure With Obesity and Reactive Airway Disease in HIV-Negative Adolescents and Young Adults. (1st February 2020) - Fourman, Lindsay T.
Abstract : Background: HIV-negative individuals with in utero HIV exposure represent an emerging population, exceeding 18 million people worldwide. Long-term clinical outcomes among HIV-exposed uninfected (HEU) individuals into adolescence and young adulthood remain unknown. Setting: US academic health system. Methods: In this observational cohort study, we leveraged a patient data registry to identify 50 HEU adolescents and young adults. We also identified 141 HIV-unexposed controls that were matched to HEU subjects up to 3:1 on age of last encounter (±2 years), birthdate (±5 years), sex, race/ethnicity, and zip code. All subjects were born since January 1, 1990, with medical records available into adolescence and young adulthood. Primary outcomes were most recent body mass index (BMI) z-score and presence of reactive airway disease (RAD). Records were manually reviewed to extract health information. Results: Fifty HEU adolescents and young adults (18 ± 3 years, 54% men) and 141 matched controls (19 ± 3 years, 54% men) were compared. HEU individuals had a higher BMI z-score (1.12 ± 1.08 vs. 0.73 ± 1.09, P = 0.03) and an increased prevalence of obesity (42% vs. 22%, P = 0.009) compared with controls. HEU subjects also had a higher prevalence of RAD vs. controls (40% vs. 23%, P = 0.03). These differences persisted on adjusting for demographic, socioeconomic, maternal, and birth-related factors. Maternal prenatal CD4 + T-cell count was inversely associated with BMI z-score among HEU adolescents (r = −0.47, P = 0.01). Conclusions: HEU adolescents and young adults exhibited a heightened prevalence of obesity and RAD compared with HIV-unexposed controls. Additional studies are needed to optimize care for the expanding population of HEU individuals transitioning to adulthood. Abstract : Supplemental Digital Content is Available in the Text.
