Summary
This summary is machine-generated.

Computerized tailored reports did not significantly boost physical activity in primary care patients. Both intervention and control groups showed increased activity, but the difference between them was not statistically significant at six months.

Area of Science:

  • Behavioral science
  • Public health
  • Digital health interventions

Background:

  • Computerized tailored interventions offer a potential cost-effective approach for behavior change.
  • This study investigated the impact of personalized physical activity reports on patients in primary care settings.

Purpose of the Study:

  • To evaluate the effectiveness of computerized tailored physical activity reports in increasing physical activity levels among primary care patients.
  • To assess the impact of these digital interventions at a six-month follow-up period.

Main Methods:

  • A two-group randomized clinical trial design was employed, with physicians as the unit of randomization.
  • Adult patients (n=394) from primary care settings received either tailored physical activity feedback reports or general health reports.
  • Physical activity was measured using the 7-Day Physical Activity Recall interview at six months.

Main Results:

  • The intervention group showed a mean increase of 139 minutes of physical activity, while the control group increased by 109 minutes.
  • No statistically significant difference in physical activity at six months was observed between the intervention and control groups after adjusting for baseline activity and gender (p=0.45).
  • Participant retention rate was high at 89.6%.

Conclusions:

  • Computerized tailored physical activity reports did not lead to a significant increase in physical activity compared to general reports in this primary care population.
  • Physical activity levels increased in both groups, suggesting a potential general benefit of monitoring or reporting, but the tailored intervention did not provide additional significant benefit.
  • Further research may be needed to optimize digital interventions for behavior change in diverse primary care populations.
