Summary of Community Preventive Services Task Force Recommendation

The Community Preventive Services Task Force (CPSTF) recommends community-based digital health interventions to increase healthy eating and physical activity among adults interested in improving these behaviors.

Major Findings

The CPSTF finding is based on evidence from a systematic review of 31 studies (search period January 2009 to June 2020). Evidence showed interventions led to the following outcomes. A mobile phone sits on a table near fruits and vegetables.

  • Participants ate more fruits and vegetables and fewer unhealthy foods, consumedfewer calories overall, and improved weight-related and clinical outcomes.
  • Adults increased or maintained the amount of time they engaged in physicalactivity, with the greatest improvements reported for those who were less activebefore the intervention.

What are Digital Health and Telephone Interventions to Increase Healthy Eating and Physical Activity?

These interventions aim to increase healthy eating and physical activity by using websites, mobile apps, text messages, emails, or one-on-one telephone calls. Interventions include educational information plus one or more of the following: coaching or counseling from trained professionals; self-monitoring to record healthy eating, physical activity, or weight; or goal setting. Interventions also may include social support from peers or motivational strategies such as incentives, rewards, and gaming techniques; and computer-generated feedback.

Why is This Important?

  • Adequate physical activity combined with a diet rich in fruits and vegetables lowers adults’ risk for many chronicdiseases, such as cardiovascular disease, type 2 diabetes, obesity, and some types of cancer.1,2
  • In the United States, 1 in 2 adults get the recommended amount of aerobic physical activity and 1 in 10 adults eat therecommended amount of fruits or vegetables each day.3,4
  • In the United States, 93% of adults use the internet, 85% have access to a smartphone, and 77% have homebroadband. Digital health interventions have the potential to reach a large number of people.5-7
