Key Findings:

  • Students who were overweight or obese and participated in Get Fit and Prevention had large and statistically significant increases in PACER laps two and three years later.
  • The percentage of students in the targeted Harlem Fitness Zone (HFZ) after two and three years of participation was significantly greater than at baseline.
  • The increased percentage of students in the HFZ was generally larger for boys than girls.
For overweight and obese middle and high school students enrolled in Harlem Children’s Zone (HCZ) after-school programs, participation in Healthy Harlem led to sustained positive impacts on physical fitness, according to interim findings from Mathematica. To assess Healthy Harlem’s effectiveness, researchers monitored students during an initial baseline year and then measured program impacts after two and three years of participation. As described in this issue brief, the findings reveal that participation in Healthy Harlem’s Get Fit and Prevention components increased levels of physical fitness.
