Calculating body mass index (BMI) standard deviation is a crucial statistical measure in health and medical research. BMI is a numerical value that is used to screen for weight categories that may lead to health problems, such as underweight, overweight, or obesity.
The relevance of BMI in assessing health risks and its benefits in guiding clinical decisions and public health interventions have made it widely used in epidemiological studies. A significant historical development in BMI calculation occurred in the early 20th century when it was standardized to account for age and gender, leading to the age-adjusted and gender-adjusted BMI.
