With long-term survival of children infected with HIV, information on cognitive function at school
age is needed. To determine cognitive function among 6- to 8 year-old children exposed to HIV and to
assess factors associated with cognitive impairment, we conducted a cross-sectional study from
October 2010 to December 2011 among children whose mothers participated in a national HIV
prevention program in Harare. Cognitive function was assessed using the McCarthy Scales of
Children’ s Abilities (MSCA). Of the 306 assessed children, 32 (10%) were HIV infected, 121
(40%) exposed uninfected, and 153 (50%) unexposed uninfected. The mean (SD) General
Cognitive Index for the whole study group was 82 (15). An overall of 49 (16%) out of the 306
children had cognitive impairment with no difference in general cognitive function among the three
groups. Children with HIV infection scored lowest in perceptual performance domain, p = .028.
Unemployed caregivers, child orphanhood and undernutrition were associated with impaired cogni-
tive performance in univariate analysis. In multivariate analysis, caregiver unemployment status
remained a factor associated with cognitive impairment with an ODDS ratio of 2.1 (95% CI 1.03–
3.36). In a cohort of 6- to 8-year-olds, HIV infection did not show evidence of significant difference
in general cognitive function. Children infected with HIV had major deficits in perceptive perfor-
mance. Lower socioeconomic status was associated with cognitive impairment. In resource-
constrained settings, strategies aimed at poverty alleviation and good nutritional management should
complement early infant diagnosis and treatment of HIV in order to optimize neurocognitive potential.

Globally, approximately 780 million children younger than 15 years fail to reach their
developmental potential due to brain injury associated with cognitive impairment (Olness,
2003). In low-income communities, cognitive development is influenced by multiple
factors including birth asphyxia (de et al., 2006), malnutrition, micronutrient deficiencies
