Our Research

Project Healthy Schools includes a research component designed to study the program’s effects on lifestyle, markers of cardiovascular risk, and obesity. Data from behavioral questionnaires and optional health screenings show important improvements in middle school students’ self-reported health behaviors and physiologic measures. Key findings include:

Results to Date

Over 32,433 sixth graders in more than 50 schools in Michigan have participated in the program. Of these students, over 12,280 have been part of our research, including 2,800 students who participated in optional health screenings. Research results demonstrate that this program has improved the health of the students it has reached.

  • 71% of students indicate, by standardized questionnaire, that they are changing their behaviors in a favorable way.
  • Behavioral highlights from post-program survey results from the 2013-2014 school year show that students increased fruit, vegetable and milk consumption; decreased fried meat and chocolate consumption; decreased TV and video game screen time; and increased vigorous and moderate exercise.
  • Physiologic screenings show improvements in measures such as serum cholesterol, LDL cholesterol, triglyceride levels, blood sugar, and measures of fitness.
  • Low/middle income communities’ children are at higher risk based on obesity rates and physiologic measures, but appear to benefit even more from the program.
  • Among all schools, children at highest risk, based on risk factors such as blood pressure and cholesterol, seem to get the most benefit.
  • Benefits appear to be sustained, not just after the five month intervention, but also at the end of years one, two and three post-PHS.

The first graph below illustrates the long term effectiveness of the program as measured in a group of almost 600 students in Ann Arbor for 3 years following the intervention.

Health Risk Indicator Levels

This graph compares the baseline and follow-up measurements from PHS for students from Ann Arbor, an affluent community, with those from Ypsilanti students, a more diverse, lower socioeconomic community. The Ypsilanti students made greater physiological improvements from baseline than the Ann Arbor students.
