Objective: To study the effects of starting antiretroviral treatment (ART) prior the age of two years on the growth (height and weight) of HIV-infected children. Methodology: This was a retrospective cohort study. HIV-infected children on ART aged less than 15 years were divided into two groups Group 1 (G1) comprising children who started ART prior 2 years and Group (G2) those put on treatment thereafter. Main Measures: Percentage of children with growth retardation measured by Height for Age (H/A) and Weight for Age (W/A) < ？2 standard deviation (SD) and associated factors of growth retardation. Statistical analysis was performed using SPSS 20 software, with p < 0.05 considered statistically significant. Results: In total, we included 90 subjects. The median age was 10 years with a slight female predominance (51.2%). Most children were asymptomatic at the time of the study (96.6%), compliant with treatment (81%), 54.8% of children were on cotrimoxazole, 33% knew their status. At initiation, underweight was predominant in group 1 compared to group 2 (52% versus 29.5%; p = 0.015). Conversely, stunted growth predominated in G2 compared to G1 but without significant difference (38% versus 50%; p = 0.147). At the time of our study (median age of 10 years), catch-up height and weight predominated in G1 compared to G2; only a small proportion remained below ？2SD (4% versus 18.2%; p = 0.015 and 9% versus 29.5%; p = 0.006 respectively for underweight and stunted growth). Conclusion andGlobal Health Implications: Growth retardation was common at ART initiation. Catch-up in height was more evident in the early treatment group. Initiation of ART before the age of 2 years rather influences children’s height than weight. The result of this study further emphasizes the need of early ART and closed clinical monitoring to better assess the impact of ART in areas with high rates of undernutrition.
