The physiological and biomechanical changes that occur during pregnancy make accurate measurement of physical activity PA a challenge during this unique period. The Global Physical Activity Questionnaire GPAQ has been used extensively in low-to-middle income countries, but has never been validated in a pregnant population. In this longitudinal study, 95 pregnant women mean age: 29.5±5.7 years; BMI: 26.9±5.0 kg-m2 completed the GPAQ and were asked to wear an accelerometer for 7 days at two time points during pregnancy 14–18 and 29–33 weeks gestation. There was a significant difference between accelerometry and GPAQ when measuring moderate-to-vigorous physical activity MVPA at 29–33 weeks gestation 16.6 vs 21.4 min-day; p = 0.02 as well as sedentary behaviour SB at both 14–18 weeks 457.0 vs 300 min-day; p < 0.01 and 29–33 weeks gestation 431.5 vs 300 min-day; p < 0.01. There was poor agreement between the GPAQ and accelerometry for both PA and SB at both time points ICC: -0.05–0.08. Bland Altman plots indicated that the GPAQ overestimates PA by 14.8 min-day at 14–18 weeks and by 15.8 min-day at 29–33 weeks gestation. It underestimates SB by 127.5 min-day at 14–18 weeks and by 89.2 min-day at 29–33 weeks gestation. When compared to accelerometry, the GPAQ shows poor agreement and appears to overestimate PA and underestimate SB during pregnancy.
