Growth Patterns of HIV Infected Indian Children in Response to ART: A Clinic Based Cohort Study
To describe catch-up growth after antiretroviral therapy (ART) initiation among children living with human immunodeficiency virus (CLHIV), attending a private clinic in India.
This is a retrospective analysis of data of CLHIV attending Prayas clinic, Pune, India. Height and weight z scores (HAZ, WAZ) were calculated using WHO growth charts. Catch-up growth post-ART was assessed using a mixed method model in cases where baseline and at least one subsequent follow-up HAZ/WAZ were available. STATA 12 was used for statistical analysis.
During 1998 to 2011, 466 children were enrolled (201 girls and 265 boys; median age = 7 y). A total of 302 children were ever started on ART; of which 73 and 76 children were included for analysis for catch up growth in WAZ and HAZ respectively. Median WAZ and HAZ increased from −2.14 to −1.34 (p = 0.007) and −2.42 to −1.94 (p = 0.34), respectively, 3 y post ART. Multivariable analysis using mixed model (adjusted for gender, guardianship, baseline age, baseline WAZ/HAZ, baseline and time varying WHO clinical stage) showed gains in WAZ (coef = 0.2, 95 % CI: −0.06 to 0.46) and HAZ (coef = 0.49, 95 % CI: 0.21 to 0.77) with time on ART. Lower baseline WAZ/HAZ and older age were associated with impaired catch-up growth. Children staying in institutions and with baseline advanced clinical stage showed higher gain in WAZ.
The prevalence of stunting and underweight was high at ART initiation. Sustained catch-up growth was seen with ART. The study highlights the benefit of early ART in achieving normal growth in CLHIV.
