Objective: Haemophilus Influenzae Type B (Hib) causes infections of pneumonia, meningitis, epiglottises and other invasive diseases exclusively among children under age five. The occurrence of these infections may impair child growth by causing micronutrient deficiency. The aim of this study was to examine the association between vaccination against Hib and child anthropometric outcomes in India.
Data and Methods: The study uses longitudinal data from first and second waves of Young Lives Study (YLS) conducted in Andhra Pradesh, India during 2002 (child aged 5-21 months) and 2006-07 (child aged 54-76 months). The study included 1824 children that had complete information on Hib vaccine, child anthropometric outcomes and other potential confounding variables in each wave of YLS. The outcome variables of interest are childhood stunting, underweight, wasting and thinness in wave-2.
Results: Result shows that a higher percent of children were stunted and underweight among those who were not vaccinated against Hib (39% & 48% respectively) as compare to those who were vaccinated (31% and 39% respectively).The result of multivariate analysis also shows that childhood stunting and underweight was significantly lower among children who were vaccinated against Hib (odds ratio: 0.77, 95% CI: 0.62-0.96 and odds ratio: 0.80, 95%C.I: 0.64-0.99 respectively) as compare to the unvaccinated children. Moreover, about 9% of stunting and 10% of underweight could be prevented by adopting vaccination against Hib in India.
Conclusion: Study concludes that vaccination against Hib- in addition to being a major intervention for reducing childhood infectious disease and mortality- can be considered as a potential tool for reducing the burden of undernutrition in India. Therefore, the inclusion of Hib vaccine into universal immunization programme will be helpful to reduce the burden of undernutrition in India.
