Introduction:Sex differences in cognition of HIV positive (HIV+) patients are controversial. We aimed to investigate the relationship between cognition, HIV status, and sex, in a highly homogenous cohort of young Romanians parenterally infected during early childhood.Methods:In total, 250 HIV+ participants were compared with age-matched HIV negative (HIV-) controls (n=72) in a cross-sectional study. After standardized neurocognitive, psychological testing and medical evaluation, linear regression was used to assess the effect of sex and HIV on neurocognitive outcomes.Results:Study participants were on average 23 years old with balanced sex distribution (% women=52% vs. 43%). HIV- were more educated (12.7 vs. 11.6 years, P=0.002).HIV+ status was associated with a lower global performance (=-0.22, P<0.001), after controlling for age and education. HIV+ women had better previous and current HIV-associated markers. The effect of HIV on global cognition did not differ between sexes in most cognitive domains (=0.07, P=0.14). An interaction between sex, HIV status, and cognitive functioning was found in the psychomotor domain. HIV+ women had worse motor skills than HIV- women (=-0.32, P<0.001) suggesting a specific effect of HIV on motor functioning in women only. Moreover, current CD4(+) less than 200 cells/l (P=0.013) and longer time lived with CD4(+) less than 200 cells/l (P=0.023) were negatively correlated with the motor scaled score in women (=-0.22, P=0.034).Conclusion:Despite less advanced disease in women, long-term HIV infection has an equally detrimental effect on cognitive performances of both sexes, in all cognitive domains, except the psychomotor domain where women are preferentially affected.
