Background: This study attempts to assess the differentials of cognitive development and nutrition of school children in tribal areas of Jharkhand, India.
Methodology: A cross-sectional study was carried out in 16 schools of Jharkhand amongst 962 children during the period of November to December 2017. Anthropometry, hemoglobin and IQ tests were assessed along-with their socio-demographic characteristics using standard procedures after obtaining their guardian's consent. Various tests of significance were used such as an independent sample t-test and Fisher's exact test along with multinomial logistic regression for determination of predictors for low-normal to borderline IQ among school children.
Results: Stunting and thinness were noted in 38% and 35% children, respectively, whereas anemia and low IQ were observed in more than 4/5th of the total children assessed. Anemia was more common in children >12 years of age and IQ was lower in tribal ethnic children (p < 0.05) amongst socio-demographic characteristics. Among the predictors, only tribal ethnicity appeared to be associated with low IQ [odds ratio (OR)-1.85; 95% confidence interval (CI) - 1.25, 2.75].
Conclusion: Despite various nutrition-related programs being run in government schools, the malnutrition and hemoglobin status of the children presents a poor picture. Cognitive development of children particularly tribal children is unsatisfactory and needs to be worked upon by government agencies.
