Vitamin A deficiency is a common form of micronutrient malnutrition.  Vitamin A supplementation reduces night blindness, child morbidity and mortality. This paper tries to explore the socio-demographic causes of receipt of vitamin A in selected lower-middle income and low income countries by analyzing the data of the demographic and health surveys from 2012 and 2016 using PASW 18.0 software. Multivariate binary logistic regressions were conducted to explore the role of sociodemographic covariates in the receipt of vitamin A supplementation. In addition, random forest (RF) analyses were conducted using Python 3.6.  It was found that after adjusting for related socio-economic and demographic factors, mother’s work status and education and among mass media channels, exposure to television seems to play an important role in predicting the receipt of vitamin A in the selected countries in Asia, while education of the mother was significantly associated with the receipt of vitamin A in the selected countries of Africa. In all the selected countries in both the regions, the RF analyses revealed mother’s education followed by wealth index and mass media (TV), as the variable of most importance.  Mother’s education and mass media seems to be prime factors in making the mothers aware about the vitamin A campaign and exhorting her to take her child to obtain vitamin A.
