Paediatric HIV care in sub-Saharan Africa: Clinical presentation and 2-year outcomes stratified by age group

Abstract

Objectives: To examine age differences in mortality and programme attrition amongst paediatric patients treated in four African HIV programmes. Methods: Longitudinal analysis of data from patients enrolled in HIV care. Two-year mortality and programme attrition rates per 1000 person-years stratified by age group (<2, 2-4 and 5-15 years) were calculated. Associations between outcomes and age and other individual-level factors were studied using multiple Cox proportional hazards (mortality) and Poisson (attrition) regression models. Results: Six thousand two hundred and sixty-one patients contributed 9500 person-years; 27.1% were aged <2 years, 30.1% were 2-4, and 42.8% were 5-14 years old. At programme entry, 45.3% were underweight and 12.6% were in clinical stage 4. The highest mortality and attrition rates (98.85 and 244.00 per 1000 person-years), and relative ratios (adjusted hazard ratio [aHR] = 1.92, 95% CI 1.56-2.37; incidence ratio [aIR] = 2.10, 95% CI 1.86-2.37, respectively, compared with the 5- to 14-year group) were observed amongst the youngest children. Increased mortality and attrition were also associated with advanced clinical stage, underweight and diagnosis of tuberculosis at programme entry. Conclusions: These results highlight the need to increase access, diagnose and provide early HIV care and to accelerate antiretroviral treatment initiation for those eligible. Adapted education and support for children and their families would also be important. © 2013 John Wiley & Sons Ltd.
