2022, VĆ”squez GĆ³mez, Jaime, FaĆŗndez Casanova, CĆ©sar, Souza de Carvalho, Ricardo, Castillo Retamal, Franklin, Valenzuela Reyes, Pedro, Concha Cisternas, Yeny, Luna Villouta, Pablo, Ɓlvarez, Cristian, HernĆ”ndez Mosqueira, Claudio, Godoy Cumillaf, AndrĆ©s, Cigarroa, Igor, Garrido-MĆ©ndez, Alex, Matus-Castillo, Carlos, Castillo Retamal, Marcelo, Leao Ribeiro, Ivana

COVID-19 causes cardiovascular and lung problems that can be aggravated by confinement, but the practice of physical activity (PA) could lessen these effects. The objective of this study was to evaluate the association of maximum oxygen consumption (VO2max) with vaccination and PCR tests in apparently healthy Chilean adults. An observational and cross-sectional study was performed, in which 557 people from south-central Chile participated, who answered an online questionnaire on the control of COVID-19, demographic data, lifestyles, and diagnosis of non-communicable diseases. VO2max was estimated with an abbreviated method. With respect to the unvaccinated, those who received the first (OR:0.52 [CI:0.29;0.95], p = 0.019) and second vaccine (OR:0.33 [CI:0.18;0.59], p = 0.0001) were less likely to have an increased . VO2max. The first vaccine was inversely associ- ated with . VO2max (mL/kg/min) (Ī²:āˆ’1.68 [CI:āˆ’3.06; āˆ’0.3], p = 0.017), adjusted for BMI (Ī²:āˆ’1.37 [CI:āˆ’2.71; āˆ’0.03], p = 0.044) and by demographic variables (Ī²:āˆ’1.82 [CI:āˆ’3.18; āˆ’0.46], p = 0.009); similarly occur for the second vaccine (Ī²: between āˆ’2.54 and āˆ’3.44, p < 0.001) on models with and without adjustment. Having taken a PCR test was not significantly associated with VO2max (mL/kg/min). It is concluded that vaccination significantly decreased . VO2max, although it did not indicate cause and effect. There is little evidence of this interaction, although the results suggest an association, since V O2max could prevent and attenuate the contagion symptoms and effects.

Nivel de actividad fĆ­sica en personas mayores chilenas que han sufrido caĆ­das

2021, Concha Cisternas, Yeny, Leiva OrdoƱez, Ana Marƭa, Troncoso-Pantoja, Claudia, Martƭnez Sanguinetti, Marƭa Adela, Cigarroa, Igor, Lasserre Laso, Nicole, Matus-Castillo, Carlos, Ulloa, Natalia, Naza, Gabriela, Dƭaz Martƭnez, Ximena, Garrido-MƩndez, Alex, Petermann Rocha, Fanny, Celis Morales, Carlos

Las caĆ­das limitan las actividades de la vida diaria. Actualmente se desconoce cĆ³mo los niveles de actividad fĆ­sica (AF) varĆ­an luego de sufrir una caĆ­da. Objetivo: investigar los niveles de prĆ”ctica de actividad fĆ­sica de personas mayores que han reportado caĆ­das en los Ćŗltimos 12 meses. MĆ©todos: Se incluyeron 1.254 participantes ā‰„ 60 aƱos de Encuesta Nacional de Salud (ENS) 2009-2010. La prevalencia de caĆ­das en los Ćŗltimos 12 meses se determinĆ³ mediante auto reporte. Los niveles de AF y el tiempo sedente se determinaron a travĆ©s del cuestionario Global Physical Activity Questionnaire (GPAQ). La asociaciĆ³n entre caĆ­das y AF fue investigada mediante regresiĆ³n lineal. Resultados: El 70,5% [95% IC: 68,0; 72,8] de las personas mayores no reportaron caĆ­das, mientras que un 19,4% [95% IC: 17,4; 21,5] reportĆ³ haber sufrido entre 1-2 caĆ­das y un 10% [95% IC: 8,4; 11,8] ā‰„3 caĆ­das en los Ćŗltimos 12 meses. En comparaciĆ³n al grupo que reportĆ³ no sufrir caĆ­das, aquellos que sufrieron ā‰„3 caĆ­das realizaban 79,2 minutos menos de AF total/dĆ­a. Resultados similares fueron observados para AF de transporte y AF moderada. No se encontraron diferencias para tiempo sedente o AF vigorosa. ConclusiĆ³n: Personas mayores que sufrieron caĆ­das en los Ćŗltimos 12 meses reportaron realizar menos actividad fĆ­sica que sus contrapartes que no experimentaron caĆ­das. A mediano y largo plazo, estos cambios en la actividad fĆ­sica podrĆ­an contribuir a resultados de salud adversos en una poblaciĆ³n.

Adiposidad corporal, estilos de vida y nivel de actividad fƭsica en mujeres dueƱas de casa y trabajadoras remuneradas chilenas

2019, Concha Cisternas, Yeny, Petermann-Rocha, Fanny, VĆ”squez-GĆ³mez, Jaime A., Matus-Castillo, Carlos, Leiva, Ana MarĆ­a, MartĆ­nez, MarĆ­a Adela, Garrido-MĆ©ndez, Alex, Diaz-Martinez, Ximena, Molina-Sotomayo, Edgardo, Pavez-Adasme, Gustavo, Carrasco BeltrĆ”n, Hernaldo, Silva-Urra, Jaime, Beltran, Ana Rosa, Celis-Morales, Carlos

En Chile existe escasa evidencia en relaciĆ³n a las caracterĆ­sticas de los estilos de vida en mujeres dueƱas de casa versus mujeres con trabajos renumerados. El objetivo del estudio fue comparar marcadores de adiposidad, hĆ”bitos de consumo asociados a estilos de vida y nivel de actividad fĆ­sica (AF) en mujeres dueƱas de casa y trabajadoras remuneradas chilenas. Se compararon variables de adiposidad como el Ć­ndice de masa corporal (IMC), peso corporal, perĆ­metro de cintura (PC), estilos de vida y niveles de AF (transporte, moderada y vigorosa intensidad y tiempo sedente) de 2.232 participantes de la Encuesta Nacional de Salud 2009-2010. Las dueƱas de casa, en comparaciĆ³n con las trabajadoras renumeradas, presentaron un mayor IMC (27,9 vs. 20,0 kg/m2 , p<0,0001) y PC (98,3 vs. 95,6 cm, p<0,0001). El tiempo destinado a la prĆ”ctica de AF de trasporte (42,5 vs. 51,5 min/dĆ­a, p= 0,009), moderada (94,2 vs. 128,4 min/dĆ­a, p<0,0001) y vigorosa (25,06 vs. 53,49 min/dĆ­a, p<0,0001) fue menor en dueƱas de casa que en trabajadoras renumeradas. Por el contrario, las dueƱas de casa destinaron menor tiempo al desarrollo de actividades sedentes (2,71 vs. 3,26 horas/dĆ­a, p<0,0001), ademĆ”s mostraron un menor consumo de alcohol (30,5 vs. 43,2 g/dĆ­a, p= 0,021) en comparaciĆ³n a trabajadoras renumeradas.

2020, Concha Cisternas, Yeny, MartĆ­nez-Sanguinetti, MarĆ­a Adela, Leiva, Ana MarĆ­a, Garrido-MĆ©ndez, Alex, Matus-Castillo, Carlos, DĆ­az-MartĆ­nez, Ximena, Salas, Carlos, RamĆ­rez AlarcĆ³n, Karina, Martorell, Miquel, Cigarroa Cuevas, Igor, Lasserre-Laso, Nicole, Troncoso-Pantoja, Claudia, De Moraes Ferrari, Gerson Luis, LabraƱa, Ana MarĆ­a, Parra, Solange, Petermann-Rocha, Fanny, Celis-Morales, Carlos

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.

2019, Celis Morales, Carlos, RodrĆ­guez RodrĆ­guez, Fernando, MartĆ­nez Sanguinetti, MarĆ­a, Leiva, Ana MarĆ­a, Troncoso-Pantoja, Claudia, Villagran-Orellana, Marcelo, Salas Bravo, Carlos, DĆ­az MartĆ­nez, Ximena, Cigarroa Cuevas, Igor, Concha Cisternas, Yeny, Ɓlvarez, Cristian, BeltrĆ”n, Ana, VĆ”squez GĆ³mez, Jaime, Pavez Adasme, Gustavo, Luarte, CristiĆ”n, Molina, Edgardo, YƔƱez Silva, Aquiles, Matus-Castillo, Carlos, Petermann Rochaa, Fanny, Garrido-MĆ©ndez, Alex

La prĆ”ctica regular de actividad fĆ­sica (AF) se asocia a un nĆŗmero importante de beneficios sobre la salud, incluyendo la reducciĆ³n de enfermedades cardiovasculares, diabetes mellitus tipo 2, hipertensiĆ³n arterial, depresiĆ³n, demencia y algunos tipos de cĆ”ncer, como de colon y mamas (Figura 1). Se estima que el 9% de mortalidad prematura por cualquier causa (equivalente a 5.3 millones de muertes por aƱo), se podrĆ­an prevenir si la poblaciĆ³n cumpliera con las recomendaciones de AF, es decir, realizara al menos 150 minutos de AF de intensidad moderada o >75 minutos de AF de intensidad vigorosa por semana.

ĀæCuĆ”l es la asociaciĆ³n entre actividad fĆ­sica, sedentarismo y riesgo de desarrollar cĆ”ncer en poblaciĆ³n adulta? Una revisiĆ³n de la literatura

2021, Parra Soto, Solange, MartĆ­nez Sanguinetti, MarĆ­a Adela, Cigarroa, Igor, DĆ­az MartĆ­nez, Ximena, Matus-Castillo, Carlos, Garrido-MĆ©ndez, Alex, Concha Cisternas, Yeny, Ferrari, Gerson, VĆ”squez GĆ³mez, Jaime, Castillo Retamal, Marcelo, Petermann Rocha, Fanny, Celis Morales, Carlos

La prĆ”ctica regular de actividad fĆ­sica (AF) ha sido asociada a importantes beneficios metabĆ³licos, como tambiĆ©n a la disminuciĆ³n del riesgo de desarrollar algunos tipos de cĆ”ncer. El objetivo de esta revisiĆ³n especial es sintetizar la evidencia cientĆ­fica existente sobre la asociaciĆ³n de los niveles de AF y el riesgo de desarrollar cĆ”ncer. Esto permitirĆ” una mejor orientaciĆ³n a futuras polĆ­ticas pĆŗblicas destinada a aumentar los niveles de AF en la poblaciĆ³n chilena. Se buscaron los Ćŗltimos reportes mundiales y nacionales sobre AF y cĆ”ncer en conjunto con una bĆŗsqueda de artĆ­culos cientĆ­ficos en las bases de datos de Pubmed, Web of Sciences, Scopus, Medline, Scielo y Google Scholar utilizando las siguientes palabras claves: ā€œExerciseĀ», Ā«NeoplasmsĀ», ā€œCancerā€, ā€œColorectalā€, ā€œBreastā€, ā€œEndometriumā€, ā€œPhysical activityā€, ā€œExerciseā€, ā€œSedentaryā€ and ā€œSportsā€. Esta revisiĆ³n entrega evidencia sobre la asociaciĆ³n de la AF con un menor riesgo de mĆŗltiples tipos de cĆ”ncer, incluyendo cĆ”ncer colorrectal, mama y endometrio, pero aĆŗn se necesita mĆ”s investigaciĆ³n con relaciĆ³n a la asociaciĆ³n entre AF y otros tipos de cĆ”ncer.

Association between different modes of travelling and adiposity in Chilean population: Findings from the Chilean National Health Survey 2016ā€“2017

2020, Medina, Ignacio, Petermann-Rocha, Fanny, Waddell, Heather, DĆ­az-MartĆ­nez, Ximena, Matus-Castillo, Carlos, Cigarroa Cuevas, Igor, Concha Cisternas, Yeny, Salas-Bravo, Carlos, MartĆ­nez-Sanguinetti, MarĆ­a Adela, Celis-Morales, Carlos

Background: Active travel has been suggested as a feasible way of increasing physical activity levels. Although international studies have demonstrated its effect over different health outcomes and adiposity, there is still limited evidence on this topic in developing countries, such as Chile. Aim: To investigate the associations between different types of travelling and markers of obesity in the Chilean adult population. Methods: 5411 participants from the Chilean National Health Survey 2016ā€“2017 (CNHS) were included in this study. Active travel was assessed using a questionnaire. Car commuters, public transport (PT), walking and cycling were the four forms of travelling assessed. Bodyweight, body mass index and waist circumference were used as markers of adiposity. Results: Compared to car travellers, body weight, WC and BMI levels were lower for PT walking and cycling travellers. The odds for obesity (Odds ratio (OR): 0.41 (95% CI: 0.28; 0.61 p ā‰¤ 0.001) were lower for walking and the odds (OR: 0.56 (95%CI: 0.35; 0.89 p = 0.014) for central obesity were significantly lower for cyclist in comparison to car travellers. Additionally, participation in any form of active travel (walking or cycling) was low, with only 20.9% of the population reporting being active travellers. Conclusion: Active travel, such as walking and cycling, was associated with lower adiposity levels in the Chilean adult population. Promoting active travel could be a feasible strategy to tackle the high prevalence of obesity and physical inactivity in the Chilean population.
