Abstract

Introduction and Aim: Human intelligence is a cognitive process and was correlated with several anthropometric parameters. Height is one of the well-known factor that is suspected for a positive correlation with intelligence and their association is studied since many years. Similarly, obesity which has become a major health outcome of today is said to have a negative effect on intelligence. Prevalence of obesity and its co-morbidities are in a great rise in both developed and developing countries. Recent findings show that obesity could impair cognitive performance. This study focuses on the correlation of the parameters such as height and BMI(Body Mass Index) with intelligence for selected samples and underscores the significance of correlation. The objective of our study was to test whether a linear relationship exists between the IQ and the two parameters and their strength of correlation.

 

Materials and Methods: The present study was conducted at Saveetha Medical College and Hospital, Chennai. Sample consists of 50 students of age group 18-20 of phase I MBBS students and the present study was directed in the Department of Anatomy. Intelligence was measured by Standard Progressive Matrices (SPM), a non-verbal reasoning test. Height was measured in metres using stadiometer. Using height and weight values obtained from the sample, Body Mass Index (weight in kg/height in metre squares) was calculated. Mean and Standard Deviation of parameters were assessed and correlation value were calculated.

 

Results: The data were statistically analysed using correlation and regression. It showed positive correlation between height and intelligence (r=0.268) (p=0.05) and a negative correlation between obesity and intelligence (r= -0.324) (p=0.05).

 

Conclusion: Therefore, it concludes that height and intelligence were positively correlated, concomitantly obesity and intelligence were negatively correlated mainly due to increase in BMI has a deteriorating effect on intelligence.
