The brain of a child: Understanding cognitive development for children living with HIV Prof Lorraine Sherr, University College London Member Coalition for Children Affected by AIDS
Presentation AIM • Review the evidence of cognitive impact of HIV for HIV+ve and HIV exposed and Uninfected children • Explore the complexity of responding to cognitive challenges • Community Care study data the role of cash grants, and cash plus care, cash plus nutrition on cognitive outcomes • Chidotrial data to show parental factors impact on cognitive outcomes • Examine promising interventions
Cognitive development HEU HIV+ve Children Cognitive delay Systematic review – 11 studies (650 HIV affected, 736 Control 205 HIV+ve) Sig lower than controls on at least 1 measure in 7/11 studies. (Sherr et al AIDS Behav 2014, Nov 18(11) 2059-74); Le Doare et al Pediatrics 2012 Nov 130(5)e 1326-44 Morbidity and Mortality effects Slogroveet al 2016 – 22 studies, 3 specifically designed. • Systematic reviews • Sherr et al 2009; Sherr et al 2015 • McHenry et al 2018 45 Studies Both HIV+ve and HEU children had worse developmental outcomes compared to HIV Uninfected Unexposed Children.
HIV Affected(Filteau et al 2009, Sherr et al AIDS Behav 2014, Nov 18(11) 2059-74); Le Doare et al Pediatrics 2012 Nov 130(5)e 1326-44
HIV +vechildren at risk of developmental delay – Community Care Study (Sherr et al various) (n=979) Degree of delay higher among HIV positive children. HIV status remained a strong independent predictor even after adjusting for other confounders (AOR: 4.55, 95% CI: 2.29-9.04, p<0.0001)
HIV and other developmental outcomes • HIV +veworse at school • HIV +ve significantly > emotional and behavioural problems - conduct, hyperactivity-inattention, or peer problems. • HIV +ve significantly < health-related quality of life.
