Does HIV infection affect growth and puberty of Cameroonian children?

This study aimed to describe growth and pubertal development of adolescents with HIV infection under highly active antiretroviral therapy (HAART) in Cameroon.

Through an observational study, we included 74 adolescents aged 9-17 years who were taking HAART and had attended two care units in Cameroon for at least 6 months. Weight and height were measured and transferred to 2007 WHO curves for 5- to 19-year-olds. Stunting was defined by a height for age z-score less than -2 standard deviations. Wasting was defined by a BMI z-score for age less than -2 standard deviations. Pubertal development was assessed using Tanner stages. We looked into the association between HIV infection characteristics, HAART regimen, and growth/puberty abnormalities with multivariate analysis. The Mann-Whitney U-test was used to compare median values with a p-value ≤0.05.

The median age was 13 (11.2-14.7) years. Stunting affected 44% of the children. Wasting affected 9.7% of the adolescents. The age at onset of puberty was in the normal range in both boys and girls. Adolescents aged 12-14 years (OR 3.4 [95% CI, 1.3-8.8], p=0.012) with a past history of opportunistic infection and taking HAART with protease inhibitors were more likely to have stunting.

In the Cameroonian setting, growth was mainly affected by stunting, but pubertal development was normal in all patients. This may reflect the benefits of HAART in children with HIV infection.
