Association of Waist Circumference and Body Mass Index among the Students of a Medical College

Background Obesity and overweight have emerged as significant public health concerns on a global scale. In the pursuit of evaluating body composition and identifying potential health risks, two widely utilized measures are Body Mass Index and waist circumference. These anthropometric indicators are considered economical, practical, and also crucial for screening, monitoring the individual's nutritional status, and anticipating future disease risk. Objective To explore the correlation between waist circumference and Body Mass Index and find out its significance as indicators of health and nutritional status in young adults. Method The study comprises 260 healthy young adults, aged 18-25 years from pre-clinical sciences, Kathmandu University School of Medical Sciences (KUSMS). Anthropometric measurements of height (m), weight (kg), and waist circumference (cm) were recorded. Body Mass Index was calculated by using the formula as body weight (kg) divided by the square of body height (m2). Demographic factors such as age, sex, obesity, and life style factors like smoking, alcohol consumption, and physical activity were noted. Result The study found a positive correlation between Body Mass Index, waist circumference (WC) and weight. However, no association was found between waist circumference and height. The findings also indicated a notably high percentage of 17.69% participants, who were categorized as overweight, while a 9.23% fell into the underweight category. The study confirms that 83.08% of the students have moderate physical activity whereas 14.62% have insufficient and 2.31% have heavy physical activity. Conclusion The study shows a positive correlation between body mass index (BMI) and waist circumference (WC) in young adults aged 18-25 years.
