The share of children in grades 1, 4, 7 and 10 considered overweight according to the Body Mass Index. Children are considered overweight if their BMI is at or above the 85th percentile for their age and gender, and they are considered obese at or above the 95th percentile. BMI is an estimate of body fat based on height and weight.
Overweight children are at greater risk for many health problems, including high blood pressure and cholesterol, breathing problems, fatty liver disease, and type 2 diabetes, bone and joint problems. Overweight children and adolescents are also more likely to face social and psychological problems, such as stigmatization and poor self-esteem, and to be overweight as adults.
BMI-For-Age data is collected and reported annually part of the "Mass in Motion" initiative started in 2009 by the Massachusetts Department of Health in an effort to reduce the prevalence of overweight children across the state.
