ABSTRACT
Introducción: Los estudios epidemiológicos sobre enfermedades no transmisibles en Cuba requieren técnicas que determinen el nivel de actividad física de manera práctica, válida, confiable y costo-efectiva. Objetivo: Caracterizar las técnicas que miden el nivel de actividad física de cuestionarios validados por sensores de movimiento y que resulten aplicables en la población cubana. Métodos: La búsqueda se efectuó a través de bases de datos PubMed, Cochrane, LILACS y SciELO. Las palabras utilizadas en la búsqueda fueron: actividad física, actividad física/técnicas de medición, actividad física/cuestionario, inactividad física y enfermedades no transmisibles. Se consultaron documentos que hubiesen sido publicados en el periodo 2014-2019. Análisis e integración de la información: Se identificaron 66 artículos, de los cuales se seleccionaron 36 que contribuyeron al resultado final. Se describieron las características más relevantes de cada técnica, así como también las semejanzas y diferencias entre ellas. Basado en los criterios de los autores referidos y el de los autores, se definió cuál sería la técnica apropiada a utilizar. Conclusiones: Se considera que los podómetros junto con la versión corta del Cuestionario Internacional de Actividad Física (IPAQ, siglas en inglés), son las técnicas que pueden utilizarse para medir el nivel de actividad física en la población cubana(AU)
Introduction: Epidemiological studies about non-communicable diseases in Cuba require techniques that determine physical activity levels in a practical, valid, reliable and cost-effective manner. Objective: Characterize the techniques that measure the level of physical activity of questionnaires validated by movement sensors and that are applicable in the Cuban population. Methods: A search was conducted in the databases PubMed, Cochrane, LILACS and SciELO, using the descriptors physical activity, physical activity / measurement techniques, physical activity / questionnaire, physical inactivity and non-communicable diseases. The documents consulted had been published in the period 2014-2019. Data analysis and integration: A total 66 articles were identified, of which 36 were selected that contributed to the final result. A description was performed of the most relevant characteristics of each technique, as well as the similarities and differences between them. Determination was made of the appropriate technique to be used, based on criteria issued by article authors and referred authors. Conclusions: Pedometers and the short International Physical Activity Questionnaire (IPAQ) were selected as the techniques to be used to measure physical activity levels in the Cuban population(AU)

Objective To test the reliability and validity of International Physical Activity Questionnaires (long self-administrated format)( IPAQ), Chinese version on women of 12-44 years old, in Chengdu city. Methods Clustered sampling was used, according to the age distribution of investigated population. One community, one university and two middle schools (including one high school and one junior high school) in Chengdu were selected. The reliability study was conducted in a 28-day period.Participants were contacted three times within 28 days (on the 1st , the 8th and the 28th day respectively).In the validity study, participants completed the same questionnaire and Bouchard physical activity diary(PA diary) each day for seven days between visit 1 and visit 2 before comparing the IPAQ's result with Bouchard physical activity diary's for validity study. Pearson or Spearman' correlation coefficients were calculated for validity and interclass correlation coefficients for reliability according to date distribution.Results (1)One hundred and eighty six participants were recruited for the reliability study. All of them completed the first questionnaire with 143(76.88%) and 172 (92.50%) finished the second and third questionnaires. One hundred and fifty eight participants were recruited in the validity study. Qualified questionnaire accounted for 90.59 % (143). (2) Results from the test-retest reliability of the Chinese version of long self-administrated format (IPAQ) showed: the ICC after one week ranged from 0.7373 to 0.972(mean:0.870) which were higher than those interval's reliability [ ICC= 0.472-0.948 for three weeks interval (mean:0.721), and 0.473-0.925 for four weeks interval (mean:0.696)]. The ICCs of three weeks interval and four weeks interval were not significantly different. ICCs for vigorous physical activity and leisure time physical activity were the best. (3)The validity for different intensity, total physical activity and sitting time showed the correlation coefficients between IPAQ and PA diary ranged from 0.445 to 0.696, with correlation for vigorous physical activity the best (r=0.696). Conclusion IPAQ-C seemed a reliable and validated measure of physical activity for 12-44 year-old women in Chengdu city.
