A new physical activity frequency questionnaire (PAFQ) accurately estimates energy expenditure. Developed using 24-hour recall data, this tool aids in understanding physical activity

Area of Science:

  • Public Health
  • Epidemiology
  • Exercise Science

Background:

  • Accurate measurement of total energy expenditure is vital for understanding physical activity's role in disease.
  • Public health interventions require reliable methods to assess energy expenditure.

Purpose of the Study:

  • To develop a self-administered physical activity frequency questionnaire (PAFQ).
  • To create a tool for accurately estimating energy expenditure based on physical activity.

Main Methods:

  • A 24-hour recall was administered to 919 adults in Geneva.
  • Activities contributing to 95% of energy expenditure were identified for men and women.
  • The final PAFQ includes 70 activities with typical durations.

Main Results:

  • The PAFQ was validated against heart rate monitoring, a more objective method.
  • Total energy expenditure estimated by the PAFQ correlated well (r = 0.76) with heart rate monitor data.
  • The questionnaire requires approximately 20 minutes for completion.

Conclusions:

  • The self-administered physical activity frequency questionnaire (PAFQ) accurately estimates energy expenditure.
  • The data-driven design of the PAFQ enhances its reliability for public health research.
  • This validated tool can be used to assess physical activity levels and their impact on health.
