Abstract
Introduction
A limitation of the Global Physical Activity Questionnaire
(GPAQ) in assessing physical activity in India is that it does not
capture the diversity of activities across cultures and by sex. The
purpose of this study was to culturally adapt and validate the
GPAQ by using an accelerometer in Thiruvananthapuram City, India.
Methods
We developed a modified version of the GPAQ by adding a physical
activity chart specific to the locale. We identified local physical
activities through in-depth interviews, group discussions, and
observation, and used Actigraph GT3X accelerometers to validate
the modified GPAQ for a subsample of 47 women. Participants
were drawn from a cross-sectional survey of 1,303 women aged
18 to 64 years, selected by multistage cluster sampling. Spearman
rank correlation coefficients and intraclass correlation coefficients
(ICC) were calculated to determine the correlation and level of
agreement in moderate-to-vigorous physical activity (MVPA) on
the basis of accelerometer measurement and the modified GPAQ.
Results
The correlation for MVPA between the modified GPAQ (overall)
and the accelerometer (non-bouted MVPA) was 0.69 (95% confidence
interval [CI], 0.39–0.85) with a moderately high ICC of 0.78
(95% CI, 0.56–0.90). The correlation for MVPA between the
modified GPAQ and the accelerometer-based MVPA within bouts
of at least 10 minutes was 0.60 (95% CI, 0.26–0.80) with an ICC
of 0.55 (95% CI, 0.20–0.77) indicating a moderate level of agreement.
Conclusion
The GPAQ can be used for assessing physical activity among women
in India, and its adaptation and validation may be useful in
other low-income or middle-income countries where activities are
diverse in type and intensity
