On the eve of the 2012 summer Olympic Games, the first Lancet Series on physical activity established that physical inactivity was a global pandemic, and global public health action was urgently needed. The present paper summarises progress on the topics covered in the first Series. In the past 4 years, more countries have been monitoring the prevalence of(More)
Physical inactivity is one of the most important contributors to the global burden of disease and has become a global public health priority. We review the evidence on physical activity (PA) interventions, actions, and strategies that have the greatest potential to increase PA at the population level. Using the socio-ecological framework to conceptualize PA(More)
CONTEXT Latinos have one of the highest prevalences of obesity in the U.S. Efforts to address U.S. Latino health have expanded to include obesity prevention and treatment initiatives. The objectives of this review were to (1) conduct a systematic review of obesity-related treatment interventions targeting U.S. Latino adults and (2) develop evidence-based(More)
Background Latinas have disproportionately low levels of physical activity (PA) and the ecological correlates of their PA remain unclear. This study aims to test interactions between individual and environmental factors on Latinas' PA. Methods We analyzed baseline data from 436 Latinas participating in a PA randomized controlled trial in San Diego, CA [Fe(More)
Physical inactivity accounts for more than 3 million deaths per year, most from non-communicable diseases in low-income and middle-income countries. We used reviews of physical activity interventions and a simulation model to examine how megatrends in information and communication technology and transportation directly and indirectly affect levels of(More)
INTRODUCTION Physical activity (PA) prevalence among U.S. Latino/Hispanic adults of diverse backgrounds is not well known. This study describes PA among a representative sample of U.S. Latino/Hispanic adults. METHODS A population-based cohort of Hispanic/Latino adults (aged 18-74 years) participating in the Hispanic Community Health Study/Study of Latinos(More)
BACKGROUND Less than 50% of Latinas meet physical activity (PA) recommendations. Acculturation is a complex cultural phenomenon that may influence health behaviors, but associations between acculturation and Latinas' activity and sedentary levels are unclear. AIM To examine associations of acculturation with Latinas' domain-specific and total PA as well(More)
INTRODUCTION Physical inactivity is a risk factor for hypertension. The objective of this study was to examine the association between self-reported leisure-time physical activity and hypertension among Brazilian adults categorized by sex and body weight. METHODS The study used data from adult respondents in 26 capital cities and the Federal District to(More)
OBJECTIVES To describe both conditions of a two-group randomized trial, one that promotes physical activity and one that promotes cancer screening, among churchgoing Latinas. The trial involves promotoras (community health workers) targeting multiple levels of the Ecological Model. This trial builds on formative and pilot research findings. DESIGN Sixteen(More)
BACKGROUND Greater neighborhood social cohesion is linked to fewer depressive symptoms and greater physical activity, but the role of physical activity on the relationship between neighborhood social cohesion and depression is poorly understood. The purpose of the study was to examine the effects of physical activity on the association between neighborhood(More)
