Physical inactivity is an important contributor to non-communicable diseases in countries of high income, and increasingly so in those of low and middle income. Understanding why people are physically active or inactive contributes to evidence-based planning of public health interventions, because effective programmes will target factors known to cause(More)
OBJECTIVE To describe the worldwide prevalence of physical inactivity and to analyze its association with development level of each country. METHODS Pooled analysis of three multicenter studies, conducted between 2002 and 2004, which investigated the prevalence of physical inactivity in 76 countries, and comprised almost 300,000 individuals aged 15 years(More)
The perceived stress scale (PSS-10) reliability and validity were evaluated in Brazilian adults. A two-stage translation procedure was employed to achieve a Portuguese version. Participants were 793 Brazilian university teachers. The exploratory factor analysis showed two factors with eigenvalues greater than 1.0 (56.8% of variance). The Cronbach's alpha(More)
BACKGROUND Physical inactivity is a global pandemic responsible for over 5 million deaths annually through its effects on multiple non-communicable diseases.

The impact of such noncommunicable diseases on low- and middle-income countries is a major global health concern, but most studies in this area have focused on high-income countries. A better understanding of the factors that may(More)
BACKGROUND To describe the lessons learned after 10 years of use of the International Physical Activity Questionnaire (IPAQ) in Brazil and Colombia, with special emphasis on recommendations for future research in Latin America using this instrument. METHODS We present an analytical commentary, based on data from a review of the Latin American literature,(More)

BACKGROUND Community programs have been suggested to be an important and promising strategy for physical activity (PA) promotion. Limited evidence is available regarding knowledge of and participation in these programs in Latin America. OBJECTIVE To describe participation in and knowledge of community PA programs and to explore associations with(More)
INTRODUCTION Prevalence of walking and cycling for transport is low and varies greatly across countries. Few studies have examined neighborhood perceptions related to walking and cycling for transport in different countries. Therefore, it is challenging to prioritize appropriate built-environment interventions. OBJECTIVES The aim of this study was to(More)
