Older adults with lower socioeconomic status, overweight, and lower self-efficacy were more likely to drop out of a physical activity program. Early identification of these factors can improve participant retention in health interventions.

Area of Science:

  • Gerontology
  • Public Health
  • Behavioral Science

Background:

  • Physical activity interventions are crucial for older adults' health.
  • Attrition (dropout) is a significant challenge in such programs.
  • Understanding attrition factors is key to improving intervention effectiveness.

Purpose of the Study:

  • To investigate the characteristics of older adults who attrited from a 6-month physical activity intervention.
  • To identify predictors of attrition in this demographic.
  • To inform strategies for enhancing participant retention.

Main Methods:

  • Recruited 248 insufficiently active adults aged 65-74 years.
  • Intervention included walking, strength, and flexibility exercises over 6 months.

  • Compared characteristics of attrited (n=86) versus completer (n=162) participants using logistic regression.

    • Main Results:

    • Attrition rate was 35% (n=86).
    • Individuals lost to attrition resided in lower socioeconomic status areas.
    • Attrited participants were more likely to be overweight, less physically active, have lower walking self-efficacy, and higher loneliness scores.

    Conclusions:

    • Lower socioeconomic status, overweight, lower physical activity, reduced walking self-efficacy, and higher loneliness predict attrition in older adults.
    • Early assessment of these factors can identify at-risk individuals.
    • Targeted strategies can improve retention and reduce bias in physical activity interventions for seniors.
