Item Socio-demographic patterning of physical activity and sedentary behaviour in Chile: Crosssectional results from the National Health Survey 2009-2010(Oxford University Press, 2016) Celis-Morales, Carlos; Salas, Carlos; Alduhishy, Anas; Sanzana, Ruth; Martínez, María; Leiva, Ana; Diaz, Ximena; Martínez, Cristián; Álvarez, Cristián; Leppe, Jaime; Munro, Alexandra; Siervo, Mario; Willis, NaomiBACKGROUND: Surveillance of physical activity (PA) is essential for the development of health promotion initiatives. The aim of the present study was to examine the prevalence of PA and sedentary behaviour with respect to socio-demographic factors in Chile. METHODS: A representative sample of 5434 adults aged ≥15 years (59% women) who participated in the Chilean National Health Survey (2009-2010) were included. Socio-demographic data (age, sex, environment, education level, income level and smoking status) were collected for all participants. PA levels were assessed using the Global Physical Activity Questionnaire. RESULTS: 19.8% [95% CI: 18.1-21.6] of the Chilean population did not meet PA recommendations (≥600 MET min week(-1)). The prevalence of physical inactivity was higher in participants aged ≥65 years, compared with the youngest age groups and was higher in women than in men. However, it was lower for participants with high, compared with low, education or income levels. The overall prevalence of sedentary risk behaviour (spending >4 h sitting per day) was 35.9% [95% CI: 33.7- 38.2]. CONCLUSION: Physical inactivity correlates strongly with socio-demographic factors such as age, gender and educational level. Results identify social and economic groups to which future public health interventions should be aimed to increase PA in the Chilean population.Item Un mayor nivel de actividad física se asocia a una menor prevalencia de factores de riesgo cardiovascular en Chile: resultados de la Encuesta Nacional de Salud 2009-2010(Sociedad Medica de Santiago, 2015) Celis-Morales, Carlos; Salas, Carlos; Álvarez, Cristián; Aguilar-Farias, Nicolás; Ramírez Campillos, Rodrigo; Leppe, Jaime; Cristi-Montero, Carlos; Diaz Martínez, Ximena; Duran, Eliana; Labraña, Ana; Martínez, María; Leiva, Ana; Willis, NaomiBACKGROUND: Little is known about the relationship between physical activity (PA) and cardiovascular risk factors in the Chilean population. AIM: To investigate the association between different levels and intensities of PA and the prevalence of cardiovascular (CV) risk factors in Chilean adults. MATERIAL AND METHODS: Data from the National Health Survey 2009-10 including 5157 participants, provided by the Epidemiology Department of the Ministry of Health, was analyzed in this study. The prevalence of type 2 diabetes mellitus, hypertension, metabolic syndrome and dyslipidemia were determined using international criteria. PA levels were determined using the Global Physical Activity Questionnaire (GPAQ v2) and different levels of PA were derived from it (transport-related, moderate and vigorous PA). Quartiles of PA were determined to investigate the association between PA and cardiovascular risk factors. RESULTS: Twenty three percent of women and 17.1% of men did not meet the PA recommendation (≥ 600 METs.min.week-1). When prevalence of CV risk factors were compared between inactive individuals (< 600 METs.min.week-1) and active individuals (≥ 9500 METs.min.week-1) a significantly lower prevalence of diabetes mellitus (6.2% and 10%), hypertension (18.0% and 12.4%) and metabolic syndrome (8.9% and 12.1%) for women and men, respectively, was found in the active participants. Similar results were found for high versus low transport-related PA. CONCLUSIONS: Increasing levels of PA are associated with a significantly lower frequency of cardiovascular risk factors in Chilean adults.
