- Cultural adaptation and validation of the “Pregnancy Physical Activity Questionnaire” for the Portuguese populationPublication . Santos, Paula Clara; Maciel, Leonardo Y. S.; Abreu, Sandra; Mesquita, Ana Rita; Mesquita, Cristina; Lopes, Sofia; Mota, JorgeThe lack of instruments to assess the level of physical activity in pregnant women, led to the development of the PPAQ (Pregnancy Physical Activity Questionnaire), a self-administered questionnaire, which has already been translated in several countries and has already been used in several studies. Translate and adapt the PPAQ into Portuguese and test its reliability and validity. An analytical observational study was carried out. Linguistic and semantic equivalence was performed through translation and back-translation and content validity was tested by a panel of experts. To test reliability, a test-retest was performed on a sample of 184 pregnant women, with an interval of 7 days and the ICC was used. To test the criterion validity, Pearson’s correlation coefficient (r) was used between the PPAQ and the accelerometer, in a sample of 226 pregnant women. The questionnaire was considered comprehensive. The ICC values of Reliability were: total score (0.77); sedentary activities (0.87); light-intensity activities (0.76); moderate-intensity activities (0.76); vigorous-intensity activities (0.70). For criterion validity was obtained a coefficient correlation of r = -0.030, considered weak and negative, for total activity. This study describes the translation and validation process of the PPAQ questionnaire from English to Portuguese. The final version of the PPAQ was considered as a valid instrument in terms of content to measure physical activity and was referred to as being simple to apply and easy to understand. The PPAQ has content validity, excellent reliability and weak criterion validity, as in the original version.
- Physical activity during pregnancy and its effects on neonatal outcomesPublication . Santos, Paula C.; Leirós-Rodríguez, Raquel; Abreu, Sandra; Ferreira, Margarida; Alves, Odete; Mota, JorgeDespite the acknowledgement that physical activity is beneficial during pregnancy and may result in positive health outcomes for the newborn child few studies have examined this issue. This research was deemed necessary with the primary objective of identifying possible associations between adherence to American College of Sports Medicine recommendations on neonatal outcome variables at birth. An observational, longitudinal and prospective study focused on a sample of 70 pregnant women (the power score achieved was estimated to be 0.3). Data was collected in three stages (1st and 2nd trimester of pregnancy and 48 h after delivery). The variables analyzed included the physical activity measurement (with accelerometry), neonatal outcomes at birth and the mother's anxiety, dietary intake, anthropometric measures and socio-demographic and lifestyle. Results: 21.4% women were active according to physical activity recommendations. There were no significant differences in neonatal outcomes at birth when comparing adherence to physical activity recommendations and the overall activity levels of the mothers. There were also no statistically significant differences in the birth weights of babies born to active and inactive mothers. Mother's anxiety level, weight gained and dietary intake were not statistically different according to compliance with physical activity behaviour or recommendations. There is no relationship between adherence to physical activity recommendations on neonatal outcome variables at birth. There were also no significant associations with sociodemographic and lifestyle variables. There is a need to identify attitudes associated with negative physical activity behavior to reduce the incidence of comorbidities associated with sedentary lifestyles during pregnancy.
