Association of self-reported walking speed with markers of adiposity and cardiovascular risk in Chile
Background: Walking speed is a strong predictor of non-communicable diseases and mortality. Aim: To investigate the association of self-reported walking pace with adiposity, metabolic and cardiovascular markers in the Chilean population. Material and Methods: Analysis of data from 5,077 participants of the 2009-2010 National Health Survey (ENS 2009-2010). Walking speed was self-reported as average or slow pace. Body mass index (BMI), waist circumference (WC), blood pressure, blood glucose, glycosylated hemoglobin and lipid profile were the outcome. Results: In Chile, 11% (95% confidence intervals [CI]: 10.0; 12.7) of the population reported a slow walking pace. Compared with average walking people, those reporting a slow pace had a higher body weight (difference (∆) 5.65 kg [95% CI: 3.22; 8.09], p < 0.01), BMI (D 2.48 kg/m 2 [95% CI: 1.53; 3.44], p < 0.01), WC (D 6.23 cm [95% CI: 4.12; 8.34], p < 0.01), serum triglycerides (D 30,9 mg/dl [95% CI: 5,31; 57,5], p = 0.018), and lower HDL cholesterol (D -2.32 mg/dl [95% CI: -4,24; -0,34], p = 0.022). Those reporting a slow pace had also a higher odd of being obese (odds ratio (OR): 2.46 [95% CI: 1.82; 3.33], p < 0.01), being diabetic (OR: 1.54 [95% CI: 1.02; 2.40], p = 0.018) and having metabolic syndrome (OR: 2.03 [95% CI: 1.30; 3.18], p = 0.002). Conclusions: In Chilean adults, slow walking pace is associated with and unfavorable adiposity and lipid profile, including a higher probability of being obese, diabetic and having metabolic syndrome.
Prevalencia de fragilidad en personas mayores de Chile: Resultados de la Encuesta Nacional de Salud 2016-2017
Background: The assessment of frailty among older people could help to reduce its social and health burden. Aim: To determine and characterize the prevalence of frailty in Chilean older adults. Material and Methods: We studied 233 participants, aged > 60 years, participating in the Chilean National Health Survey 2016-2017. Frailty was assessed using modified Fried criteria. Thus, people classified as frail should meet at least 3 out of the 5 criteria (low strength, low physical activity, low body mass index, slow walking pace and tiredness). Results: The prevalence of frailty was 10.9% (7.7% for men and 14.1% for women). The prevalence of pre-frailty was 59.0% whereas 30.1% of participants were classified as robust. At the age of 80 years 58 and 62% of men and women were frail, respectively. These figures increased to 90 and 87% at the age of 90 years. The prevalence of pre-frailty increased from 43 to 92.1% among men and from 76% and 78% among women from the ages of 60 to 90 years, respectively. Conclusions: The prevalence of frailty increased markedly with age. It is important to implement prevention strategies to allow an early identification of high-risk individuals.
Revisión de estrategias para promover el envejecimiento activo en Iberoamérica
En Iberoamérica se reconocen variadas experiencias que favorecen un envejecimiento activo, y que pueden ser replicadas en diversas comunidades, como estrategias orientadas a una mejor calidad de vida. La presente revisión tiene como objetivo identificar intervenciones o recomendaciones orientadas al fomento de un envejecimiento activo en países de Iberoamérica. La búsqueda de evidencias se efectuó en publicaciones de artículos disponibles entre los años 2010 y 2019, utilizando las bases de datos Medline, Scopus, Scielo, Science-Direct, Biblioteca Virtual de Salud, MEDES y Dialnet. Las recomendaciones y experiencias realizadas para este grupo etario incluyen actividades clásicas como la realización de actividad física o talleres de educación en salud, pero también acciones culturales, turísticas, intergeneracionales, de fortaleciendo cognitivo, actividades intersectoriales, historias de vida, lugar de residencia o el uso de tecnologías de información. Futuras experiencias de promoción destinadas a este grupo etario deben planificarse con una mirada integradora de actividades que favorezcan la vida sana a través de la creación, la cultura y la vida saludable.
