Summary
Physical activity assessment in women showed weak agreement between the International Physical Activity Questionnaire (IPAQ) and pedometers. The IPAQ may overestimate activity levels compared to pedometer measurements.
Area of Science:
- Women's Health
- Physical Activity Measurement
- Epidemiology
Background:
- Accurate physical activity assessment is crucial for women's health.
- Menopausal transition involves physiological changes impacting physical activity.
- Comparing different measurement tools is essential for reliable data.
Purpose of the Study:
- To compare physical activity assessment between a pedometer and the International Physical Activity Questionnaire (IPAQ) in women.
- To evaluate the agreement and correlation of these two methods across different menopausal stages.
Main Methods:
- Cross-sectional study in pre-, peri-, and postmenopausal women in Southern Brazil.
- Physical activity measured using digital pedometers and the IPAQ (short version).
- Statistical analysis included Spearman correlation, Kappa index, and Bland-Altman plots.
Main Results:
- Weak concordance (k=0.110, p=0.007) and correlation (rho=0.136, p=0.02) between IPAQ and pedometer.
- Bland-Altman plots indicated systematic differences in measurements.
- Pedometer indicated higher inactivity, while IPAQ indicated higher activity levels.
Conclusions:
- There is weak agreement between the IPAQ and pedometer for assessing physical activity in women.
- The IPAQ may overestimate physical activity compared to pedometer measurements.
- Further research is needed to validate physical activity measurement tools in diverse female populations.
