Background: Adolescence is a critical period of physical and cognitive development, during which nutritional status may influence academic performance. Body Mass Index (BMI), as an indicator of nutritional status, has been increasingly studied for its potential association with scholastic achievement. However, the relationship remains inconclusive, particularly in developing countries experiencing a dual burden of malnutrition. The objective is to estimate the relationship between academic performance and BMI among adolescents. Material and Methods: The cross-sectional study was conducted on 474 students aged 13-18 years, comprising both males and females. Anthropometric data (height and weight) were collected to calculate BMI, which was ranked according to standard values. Grade Point Average (GPA) and subject-specific scores from school records were used as measures of academic performance. Data on socioeconomic status and lifestyle were also obtained. Appropriate tests were used for statistical analysis, and a p-value below 0.05 was considered significant. Results: The mean age of the participants was 15.62, 1.42, which is equivalent to 15.62 in accordance with the sample size. The mean BMI was 21.84 ± 5.36 kg/m². Among students with normal BMI, academic performance was slightly better than that of underweight and overweight/obese students, but the differences were not statistically significant (p>0.05). Conclusion: BMI was not a significant independent predictor of scholastic achievement in adolescents. Socioeconomic, lifestyle, and environmental factors appear to combine to influence academic achievement. Keywords: Body Mass Index; school achievement; Adolescents; GPA; Nutrition; Lifestyle Factors.
