Abstract
Background/aimsPaediatric HIV remains a significant challenge to children and caregivers in South Africa. Little is known about the effect of HIV infection on muscle strength in children, however potential decrease in muscle strength has been inferred to affect functional ability in these children. The aim of this pilot study was to compare the muscle strength of children infected with HIV who had been receiving highly active antiretroviral therapy (HAART) to that of children infected with HIV not receiving HAART.MethodsThe study population included a group of 16 children receiving HAART and 16 children not receiving HAART. A one-off test of muscle strength was undertaken using a hand-held dynamometer for the child, and a demographic questionnaire and social status index to their primary caregiver. Two-sample student t tests, Pearson correlation analyses, and backward regression analyses were used to analyse data.ResultsThe cluster of differentiation (CD4) count of the group on HAART was significantly higher than the group not receiving HAART. The group not receiving HAART was stronger than the HAART group. No significant correlation was shown between length of time having received HAART and muscle strength, or between CD4 count and muscle strength in the group receiving HAART. A significant negative correlation was shown between CD4 count and muscle strength in the group not receiving HAART.ConclusionFurther research is needed to establish the impact of earlier administration of HAART on muscle strength in children infected with HIV.
