Our Research

Project Healthy Schools (PHS) 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. A presentation summarizing 10 years of PHS research is available here.

Results to Date

Over 41,000 sixth graders in more than 60 schools in Michigan have participated in the program. Of these students, over 15,680 have been part of our research, including 2,790 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 2014-2015 school year show that students increased fruit and vegetable consumption; decreased sweets and chocolate consumption; decreased TV and video game screen time; and increased vigorous, moderate and muscle-strengthening exercise and sports participation.
  • 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.

These graphs demonstrate the sustained benefit of PHS in both the physiological (n=889) and behavioral (n=740) measures of Ann Arbor students over four years post-PHS intervention.

These graphs demonstrate the sustained improvement in cardiovascular risk factors post-PHS intervention in students from both Ann Arbor, an affluent community, and Ypsilanti, a more diverse, lower socioeconomic community.
