What does this measure?

The share of students in grades 7-12 who have a Body Mass Index (BMI) that is at or above the 85th percentile for their age and gender. The index is an estimate of body fat based on height and weight. 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.

Why is this important?

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.

How is our county performing?

In 2016, 38% of Berks County students in grades 7-12 were either overweight or obese, which was similar to the state as a whole (36%). The county percentage was up 6 percentage points since 2009. Pennsylvania only had a 2 percentage point increase during the same period. Berks County had a slightly higher percentage of obese grade 7-12 students (18%) as the state (17%).

The percentage of overweight and obese grade 7-12 students in 2016 was similar to Berks in Lebanon (37%), lower than Lancaster (34%) and much lower in Chester and Montgomery (both at 30%). Schuylkill (41%) had a larger percentage. Since 2009, Berks had the largest percentage point increase (6%) followed by Lancaster at 4 percentage points and Lebanon at 2 percentage points. Chester had a large decrease of 6 percentage points, Montgomery had no change in percentage, while Lehigh declined by 1 percentage point.

Notes about the data

BMI data are collected and reported annually by public school entities to the Pennsylvania Department of Health which then publishes annual reports at the county level. This information is published separately for students in grades K-6 and 7-12 and cannot be aggregated and thus is reported separately here as well.
