Abstract:
Early childhood period is the most important developmental phase in life because 
it indicates the advancement of the child in all areas of human functioning. The human 
immunodeficiency virus is neurotropic and invasion of the developing child's brain which results 
in significant developmentaldelays.The lack of an estimate on the developmental delays among 
HIV-infected infants and children could hinder early identification and early intervention 
services. Thus, this study was assessed the developmental status of HIV-infected children and 
theirrelated factors.
Objective: To determine the magnitude of developmental delay and associated factors among 
HIV-infected children at public hospitals in Guji and Borena zones, Oromia, Southern Ethiopia.
Methods and materials: A facility-basedcross-sectional studywas conducted among 422 HIV infected children from 30 October to 30 December 2021. The study participants were selected 
using simple random sampling techniques.Children's developmental delay was assessed by Age 
and stage questionnaires version three and anthropometric measurement was taken to assess 
nutritional status. Data were entered into Epi-Data version 3.1 and exported to STATA version 
14.2 for analysis. Descriptive statistics were done. Bivariate and multivariable logistic regression 
was used to measure the strength of association between dependent and independent variables. In 
all analyses, P value<0.05was considered statistically significant. 
Results: A total of 413 study participants were included in the study with a 97.9% response rate.
The magnitude of global developmental delay among HIV-infected children was 41.9% (95%CI 
(37%-47%). Maternal age 35 and above [AOR=2.2; 95% CI (1.112-4.3)], High school education 
[AOR=0.47; 95% CI (0.23-0.96)], birth order fourth and above [AOR=0.28; 95% CI (0.144-
0.54)], and stunting [AOR=2.2; 95% CI(1.4-3.42)] were associate to global developmental delay.
Conclusion:Developmental delays in HIV-infected children were high in the study 
setting.Maternal age and education status,stunting, and 4th and above birth orderwere 
factorsrelated to the global developmental delay.Further screening of developmental delays in 
children and intervention with those children who exhibit delayed development is very 
important.
