RESUMEN
Resumen Objetivo: Evaluar la validez concurrente y la confiabilidad test-retest del Global Physical Activity Questionnaire (GPAQ) y el International Physical Activity Questionnaire (IPAQ, versión corta) en una comunidad universitaria. Metodología: Un total de 76 personas de la Universidad de Antioquia, Medellín (Colombia), con edades entre 18 y 44 años, portaron un acelerómetro (ActiGraph GT3X+) durante siete días y posteriormente diligenciaron los dos cuestionarios; estos se repitieron una semana después. La validez y la confiabilidad para evaluar el gasto energético (GE) y el tiempo sedentario (TS) se determinó con el coeficiente de correlación intraclase (CCI); la concordancia para clasificar el nivel de actividad física (NAF) se evaluó con el índice de Kappa ponderado (IKp). Resultados: Para medir el GE, el IPAQ mostró una validez "moderada" (CCI=0,434, IC95%=0,231-0,600; p<0,001) y el GPAQ "pobre" (CCI= 0,335, IC95%=0,123-0,519; p<0,001); para el TS, la validez de ambos cuestionarios fue "pobre" (IPAQ: CCI=0,234, IC95%=0,011-0,435, p<0,020; GPAQ: CCI=0,231, IC95%=0,009-0,432, p<0,021). Para clasificar el NAF (bajo, moderado o alto), ambos cuestionarios mostraron concordancias "bajas" (IPAQ: IKp=0,298, p=0,001; GPAQ: IKp=0,137, p=0,119). La confiabilidad del GPAQ para evaluar el GE fue "buena/excelente" (CCI=0,838; IC95%=0,754-0,895; p<0,001) y del IPAQ fue "moderada" (CCI=0,655; IC95%=0,505-0,766; p<0,001). La confiabilidad para el TS fue "moderada" en ambos instrumentos (IPAQ: CCI=0,716; IC95%=0,583-0,811; p<0,001; GPAQ: CCI=0,736; IC95%=0,613-0,824; p<0,001). Conclusiones: Los cuestionarios mostraron poca validez para la medición del NAF y del TS. Sin embargo, ambos instrumentos presentaron una buena confiabilidad para la medición de las variables estudiadas. No se recomienda el uso de los cuestionarios para la población estudiada.
Abstract Objective: Evaluate the concurrent validity and test-retest reliability of the Global Physical Activity Questionnaire (GPAQ) and the International Physical Activity Questionnaire (IPAQ, short version) in a university community. Methodology: A total of 76 people from the University of Antioquia, Medellín (Colombia), aged between 18 and 44, carried an accelerometer (ActiGraph GT3X +) for seven days and subsequently filled out the two questionnaires; these were repeated a week later. The validity and reliability for assessing energy expenditure (EE) and sedentary time (ST) was determined with the intraclass correlation coefficient (ICC); concordance to classify the physical activity level (PAL) was evaluated with the weighted Kappa index (wKI). Results: To measure the EE , IPAQ showed a "moderate" validity (ICC = 0.434, CI 95% = 0.231-0.600; p <0.001) and the "poor" QPAQ (ICC = 0.335, CI 95% = 0.123-0.519; p <0.001); for ST , the validity of both questionnaires was "poor" (IPAQ : ICC = 0.234, CI 95% = 0.011-0.435, p <0.020; GPAQ: ICC = 0.231, CI 95% = 0.009-0.432, p <0.021). To classify the PAL (low, moderate or high), both questionnaires showed "low" concordance (IPAQ: wKI = 0.298, p = 0.001; GQAP: wKI = 0.137, p = 0.119). The reliability of the GPAQ for assessing EE was "good/excellent" (ICC = 0.838; CI 95% = 0.754-0.895; p <0.001) and the IPAQ was "moderate" (ICC = 0.655; IC 95% = 0.505-0.766 ; p <0.001). The reliability for ST was "moderate" in both instruments (IPAQ: ICC = 0.716; CI 95% = 0.583-0.811; p <0.001; GPAQ: ICC = 0.736; CI 95% = 0.613-0.824; p <0.001). Conclusions: The questionnaires showed little validity for measuring PAL and ST . However, both instruments presented good reliability for measuring the variables studied. The use of questionnaires for the population studied is not recommended.

RESUMEN
Background: The relationship between physical activity andbetter quality of life, and association between inactivity andvarious non-communicable diseases are well documented.The objective of present study was to describe pattern ofphysical activity in women attending primary health carecenters in Jeddah, and to evaluate the impact of utilizing socialmedia to encourage Physical Education in inactive women.Materials and Methods: Through a cross section studydesign, 310 attendants of the primary health care centers inJeddah were selected randomly to assess the pattern ofPhysical Education by using Global Physical ActivityQuestionnaire (GPAQ) version 2.0. Out of the detected inactivewomen, 35 were subjected to an intervention using socialmedia to encourage physical activity; the impact of interventionwas done using pre-post analysis.Results: Only 13(10.3%) of the respondents reported that theyexert vigorous activity at work, and a greater percentage167(55.5%) exerting moderate activity. Only one quarter of therespondents 73(24.3%) pointed 8 that they perform vigorousactivity in recreation and leisure time with average METs of(median, IQR: 1440: 960-2640). The overall energyexpenditure of active respondents accounted for and averageMETs of (median, IQR: 2640: 1440-5760). The number ofrespondents who had been categorized as being inactivewas 90 corresponding to 29.9% of the respondents. Afterintervention, 17(48.6%) of the originally inactive womenbecame active with a statistically significant increase inaverage METs which reached up to (median, IQR: 3100: 1380-5300) p< 0.05.Conclusion: The prevalence of inactivity of women isconsiderably high and accord similar studies in other settings,our trial in its current form using social media is effective inencouraging physical activity in physically inactive women.
RESUMEN
Objective To test the validity and reliability of global physical activity questionnaire (GPAQ) by using two methods for collecting data,and to evaluate the equality of two measure methods.Methods The physical activity (PA) in two hypertension groups was examined twice with GPAQ by using self-administered and interview methods respectively.The test-retest reliability coefficient and consistency coefficient were calculated based on the results of two groups.The criterion validity of GpAQ was assessed by adopting pedometer and international physical activity questionnaire (IPAQ).Results The intra-group relative coefficient detected by two methods had statistical difference in the aspects of,the vigorous PA (work),total moderate PA and total moderate-vigorous PA(P＜0.05).In the aspect of different grades of PA level measurement,theconsistency coefficients detected by two methods were 0.37 and 0.31 respectively;in the aspect of whether reaching recommended PA level in hypertensive patients,the consistency coefficients detected by two methods were 0.33 and 0.34 respectively.The relative coefficient detected by pedometer,IPAQ and GPAQ was 0.19-0.46.Conclusion GPAQ has good reliability and validity,is suitable to be popularized and applied in the group of chronic disease hypertension.The validity and reliability of GPAQ measured by the self-administered method are consistent to those measured by using the interview method,promptingthat the self-administered method may be used to measure PA status in population by GPAQ.
