Background: One of the side effects of cancer treatment is a low level of physical activity (PA) due to fatigue and pain. Aim: To quantify PA levels in Chilean people with cancer. Material and Methods: Analysis of the National Health Survey 2016-2017 including 6,233 participants, comparing those with and without a self-report of cancer was conducted. Levels of PA and sitting time were assessed using the Global Physical Activity Questionnaire. Results: 3% of participants [confidence intervals (CI): 2.6; 3.9] reported having cancer and 34% [95% CI: 22.7; 46.7] of these reported being physically inactive, compared to 25% [95% CI: 22.5; 27,3] of those without cancer. Participants with cancer performed 56 and 77 minutes/day lower vigorous and total PA than participants without cancer. No differences between groups were observed for commuting PA, moderate PA and sedentary time. Lower level of PA was independent of the years elapsed since the diagnosis of cancer. Conclusions: People with cancer are less physically active than their counterparts without the disease.

Comparación de los niveles de actividad física medidos con cuestionario de autorreporte (IPAQ) con medición de acelerometría según estado nutricional

2020, Dr. Garrido-Méndez, Alex, Martorell, Miquel, Labraña, Ana, Ramírez-Alarcón, Karina, Díaz-Martínez, Ximena, Rodríguez-Rodríguez, Fernando, Cigarroa, Igor, Vásquez, Jaime, Concha, Yeny, Martínez-Sanguinetti, María, Leiva, Ana, Álvarez, Cristian, Petermann-Rocha, Fanny, Salas-Bravo, Carlos, Celis-Morales, Carlos

Background: It is unknown if nutritional status could influence the accuracy of self-reported physical activity (PA) levels. Aim: To compare PA measured using the international physical activity questionnaire (IPAQ) and by accelerometry (ActiGraph) according to nutritional status in Chilean adults. Material and Methods: This is an observational cross-sectional study that used information from the GENADIO project carried out in Chile between 2009-2011. The sample consisted of 322 people. PA levels and sitting time were determined through the IPAQ self-report questionnaire and ActiGraph accelerometers (GTM1). The nutritional status was determined according to body mass index (BMI). Results: Compared with the measurement made with accelerometry, the IPAQ self-report questionnaire underestimated the levels of light PA, total PA and sedentary time in -171.5, -54.8 and -40.6 min / day, respectively. However, IPAQ overestimated the levels of moderate PA and vigorous PA in 91.0 and 47.3 min/day respectively, compared with accelerometry. Compared with normal weight, obese subjects reported higher levels of moderate PA (105.5 and 48.9 min/day, respectively) and vigorous PA (54.1 and 38.3 min/day respectively). Total PA had a greater delta of underestimation between IPAQ and accelerometer measurements in normal weight than in obese subjects (-122.1 vs -16.5 min/day, respectively). Conclusions: The measurement of PA by means of a self-report questionnaire was discrepant with its objective measurement with an accelerometer. The discrepancy is even higher in obese people.
