Body Mass Index (BMI): A widely used measure for obesity, calculated as weight (kg) divided by height (m2).
Ponderal Index: Similar to BMI but used more often in pediatric populations.
Brocca Index: A simple anthropometric measure, used as a guideline for ideal body weight based on height.
Breteau Index, however, is unrelated to obesity. It is an indicator used in entomology to measure the density of mosquito larvae and assess vector control efforts.
