Association between Working Memory and Obesity among Secondary School Children

Abstract

Introduction: Obesity is not just a term but a threat faced by the younger generation. It affects the vital systems of our body and very importantly impairs the cognitive functions of our brain. Lack of exercise, lethargy, increased usage of electronic gadgets is some of the notable reasons for childhood obesity. This study has been designed to find out how obesity is playing a role in a child’s short term memory skills. Materials and Methods: A Cross sectional epidemiological study was conducted among 125 secondary school children from random urban south Indian population. The students were asked to fill in their general details along with height, weight, hip circumference, waist circumference and asked to play a set of matching games and put in their score to measure working memory. Results: Association between corresponding memory task scores and BMI indicates a strong negative correlation (r = -.008) and (r = -.07). Conclusion: The present results therefore indicate that there is an association between obesity and poorer working memory performance in secondary school children. Therefore to conclude, the extent to which children are physically active is influenced by a multiple and interrelated factors. Addressing physical inactivity and its contribution to childhood overweight obesity requires a broad and holistic approach.
