Area of Science:

  • Health Informatics
  • Behavioral Science
  • Public Health

Background:

  • Inactive young adults with high bodyweight are a key demographic for health interventions.
  • Personalized physical activity (PA) recommendations can encourage healthier lifestyles.
  • Recommender systems offer a technological approach to tailor health advice.

Purpose of the Study:

  • To evaluate the feasibility of a recommender system for personalized PA suggestions.
  • To assess the willingness of inactive young adults to use such a system.
  • To gather user feedback on the accuracy and utility of PA recommendations.

Main Methods:

  • Developed a recommender system using data from the 2017 Behavioral Risk Factor Surveillance System.
  • Surveyed 47 young adults (mean age 23.0, mean BMI 29.4) on system interest.
  • Conducted follow-up interviews with 11 participants who received PA recommendations.

Main Results:

  • Approximately 50% of surveyed participants expressed willingness to use the recommender system.
  • Interest in the system was associated with being female and poorer self-perceived health.
  • Eight of 11 interviewees tried the recommended PA, reporting mixed reviews on accuracy.

Conclusions:

  • Recommender systems have potential for promoting physical activity adoption in young adults.
  • System improvements are needed to enhance user satisfaction and perceived accuracy.
  • Personalized PA technology could be a valuable tool in public health initiatives.
