Child Obesity - Overall Statistics for Connecticut

Reducing childhood obesity is strongly associated with improved health. Childhood obesity can have many harmful effects on the body and puts children at greater risk for high blood pressure, high cholesterol, type 2 diabetes, asthma, joint and musculoskeletal issues among others. Children with obesity tend to become obese as adults and their risk for weight related diseases tends to be more severe. Childhood obesity is determined by Body Mass Index (BMI). BMI is a screening and diagnostic tool for weight and is calculated based on a person’s weight and height. Childhood obesity is defined as a BMI at or above the 95th percentile for children of the same age and gender. The Dashboard uses BRFSS data to calculate childhood obesity based on respondent’s report of the child’s height and weight.


  • The goal of CT SIM is to reduce the percent of childhood obesity to 13.2 percent by 2020. Prior to the CT SIM implementation (2014/2015), the percent of childhood obesity was 13.5.
  • In 2016, the first CT SIM implementation year, the percentage increased to 16.0 (a 2.5 percent increase) and increased to 18.9 percent in 2017 (another 2.9 percent increase).
  • The 2016 and 2017 results show a trend moving further away from the targets.
