Obesity Surveillance

Obesity has been defined as a condition in which excess body fat has accumulated to an extent that health may be adversely affected. The classification of overweight and obesity allows the identification of individuals and groups at increased risk of morbidity and premature mortality.

Body Mass Index (BMI) provides the most useful population-based measure of obesity. For adults, a BMI of 30.0 or greater is obese. Classifications of BMI for children are derived from Growth Charts that show the distribution of weight-for-height across a range of ages and sex for a reference population.  Children with a BMI-for-age >=95th percentile are classified as obese.

Data on self-reported height and weight are collected annually for the adult population in Georgia and are useful for estimating the proportion of the population that is overweight or obese and to monitor trends. Periodic surveys administered to middle and high school students provide a population-based estimate of at risk for overweight and overweight among Georgia's youth.
