Physical inactivity was characterised as a global pandemic in the 2012 Lancet series on physical activity and health.1 The extent of the pandemic, causes and potential solutions were further explored in other papers in the 2012 and 2016 series, and recommendations derived from these papers and an associated workshop are summarised by Ding et al. 2 This paper builds on these syntheses of global knowledge and assesses progress or the lack thereof in addressing the global pandemic of physical inact...

BACKGROUND In low- and middle-income countries, sedentary behavior is widely prevalent in the young. Reliable and valid instruments are essential for evaluating sedentary behavior and physical activity in children and adolescents. OBJECTIVES To evaluate the reliability and validity of an easy to use physical activity questionnaire for children and adolescents from India. STUDY DESIGN Evaluation of a questionnaire tool. PARTICIPANTS 104 children and adolescents belonging to the age group of 10-17...

BACKGROUND: Most population-based studies from Latin America have used questionnaires to measure physical activity (PA) and sedentary behaviors (SB). Low reliability and validity of the questionnaires has limited the capacity to examine associations between PA and health. The purpose of this study was to compare self-reported and accelerometer-measured PA and SB and their associations with body composition in Latin American countries. METHODS: Data were obtained from the Latin American Study of ...

In the past few decades, the field of physical activity has grown and evolved in scope, depth, visibility and impact around the world. Global progress has been observed in research and practice in physical activity regarding surveillance, health outcomes, correlates/determinants, interventions, translation and policy. The 2012 and 2016 Lancet series on physical activity provide some of the most comprehensive global analysis on various topics within physical activity. Based on the Lancet series a...

Abstract Background Active travel such as walking or cycling has been associated with more favorable health outcomes. However, evidence on patterns of transportation in Latin America is scarce. Therefore, the aim of this study was to quantify and characterise socio-demographic patterns of public, private and active travel in Latin American countries. Methods Data from the Latin American Study of Nutrition and Health, a population-based, cross-sectional survey conducted in eight Latin American co...

Abstract Worldwide studies of physical activity and sedentary time have historically under-represented low- and middle-income countries due to the lack of surveillance data. The purpose of this paper is to describe the methods and procedures used for the assessment of physical activity and sedentary time in the Latin American Study of Nutrition and Health (Estudio Latinoamericano de Nutricion y Salud; ELANS). ELANS is a multicenter, cross-sectional and surveillance study of a nationally represen...

BACKGROUND: Although there is high prevalence of obesity and other cardiovascular risk factors among Latin American adolescents, there is limited evidence on dietary intake and physical activity (PA) patterns in this population. Therefore, we characterized anthropometry, dietary intake, PA and sitting time (ST) in adolescents aged 15-17 years from eight Latin American countries. METHODS: Six hundred seventy-one adolescents (41.4% girls) from the Latin American Study of Nutrition and Health (ELAN...

OBJECTIVES: Use of objectively measured physical activity (PA) in older adults to assess relationship between PA and risk of all-causes mortality is scarce. This study evaluated the associations of PA based on accelerometry and a questionnaire with the risk of mortality among older adults from a city in Southern Brazil. DESIGN: A cohort study. SETTING: Urban area of Pelotas, Southern Brazil. PARTICIPANTS: A representative sample of older adults (>/=60 y) from Pelotas, enrolled in 2014. MEASUREME...

Background Low levels of physical activity (PA) and prolonged sitting time (ST) increase the risk of non-communicable diseases and mortality, and can be influenced by socio-demographic characteristics. The aim of this study was to use self-report data to characterise socio-demographic patterns of PA and ST in eight Latin American countries.
