Abstract
Introduction: Obesity rates have risen rapidly in both industrialised and developing countries, across all age groups and genders. The researchers wanted to see if there was a link between body mass index (BMI) and lifestyle and academic performance among College of Medicine students at Majmaah University in Saudi Arabia. Materials and Methods: Male and female students studying at college of medicine who were registered for the academic year 2020-2021 studying in levels 2-6 were included in this cross-sectional study. A total of 269 participants were chosen as part of the sample. A pretested questionnaire was used to collect the information. Results: Males made up more than half of the participants (153, or 56.6%), with the majority (245, or 91.1%) being between the ages of 17 and 24 years. Participants' BMIs ranged from 15.2 to 43.2, with an average SD of 24.5 5.3. One hundred and fifty (55.8%) of the kids were of average weight. The statistical research indicated a link between cumulative grade point average (CGPA) and BMI. In comparison to the rest, normal-weight participants had a higher CGPA. Conclusion: Being a male, younger age, high family income, second-year level and parents' education are all linked to strong academic achievement, according to the study. Normal weight, nutritional and sleeping habits are also linked to good academic performance.
