Socioeconomic Outcomes of Adults With Perinatally Acquired Human Immunodeficiency Virus (HIV) Compared to Their Siblings Without HIV: A Nationwide Cohort Study From The Netherlands.

Background: With effective antiretroviral treatment, more children with perinatally acquired human immunodeficiency virus (HIV) reach adulthood. We assessed their long-term socioeconomic outcomes-educational level, reliance on social welfare or absence of income, and living in poverty-using a sibling comparison design to disentangle biological from familial and environmental influences. Methods: We conducted a retrospective cohort study from the Netherlands using data from the ATHENA cohort and nonpublic microdata from Statistics Netherlands (CBS). We included individuals aged ≥18 years with perinatally acquired HIV and siblings without HIV (identified through maternal CBS data). Logistic regression evaluated associations between sociodemographic and HIV-related factors with outcomes. Generalized estimating equations assessed differences between groups. Results: Among 145 individuals with HIV, 12% had low educational level, 17% relied on social welfare or had no income, and 15% lived in poverty. Receiving HIV care before 1996 was associated with low educational level (odds ratio [OR], 4.58 [95% confidence interval {CI}, 1.46-14.43]; P = .01), while older age increased odds of having no income or reliance on social welfare (OR, 1.24/year [95% CI, 1.10-1.39]; P = .0001). Older age at HIV diagnosis was linked to living in poverty (OR, 1.20/year [95% CI, 1.06-1.34]; P = .003). Compared to 94 siblings, individuals with HIV had higher odds of low education (adjusted OR [aOR], 6.59 [95% CI, 1.91-22.73]; P < .01) and having no income or social welfare reliance (aOR, 2.54 [95% CI, 1.05-6.12]; P = .04). Poverty rates did not differ significantly between groups. Conclusions: Adults with perinatally acquired HIV face educational and economic disadvantages compared to their siblings without HIV, highlighting the lasting impact of perinatal HIV beyond familial or environmental background.
