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 physical activity across countries of low, middle, and high income. The model suggested that the direct and potentiating effects of information and communication technology, especially mobile phones, are nearly equal in magnitude to the mean effects of planned physical activity interventions. The greatest potential to increase population physical activity might thus be in creation of synergistic policies in sectors outside health including communication and transportation. However, there remains a glaring mismatch between where studies on physical activity interventions are undertaken and where the potential lies in low-income and middle-income countries for population-level effects that will truly affect global health.

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 interventions, we show that PA can be targeted at multiple levels of influence and by multiple sectors outside the health system. Examples of promoting PA on a national scale are presented from Finland, Canada, Brazil, and Colombia. A strong policy framework, consistent investment in public health programs, multi-sectoral support and actions, and good surveillance characterize each of these success stories. Increasing PA globally will depend on successfully applying and adapting these lessons around the world taking into account country, culture, and context.

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 from March 2008 to June 2011 (N=16,415) was recruited in four urban areas from Miami, the Bronx, Chicago, and San Diego. Participants wore an Actical hip accelerometer for 1 week (n=12,253) and completed the Global Physical Activity Questionnaire (n=15,741). Data were analyzed in 2015. Results Based on accelerometry, Hispanics/Latinos engaged in 23.8 min/day (10.3 min/day when only considering minutes from sustained 10-min bouts) of moderate to vigorous PA (MVPA). Individuals of Puerto Rican and Dominican background had the most min/day of MVPA (32.1 and 29.1, respectively), whereas those of Cuban background had the fewest (15.3). Based on the Global Physical Activity Questionnaire, 65% of Hispanic/Latinos met the aerobic component of 2008 Physical Activity Guidelines for Americans. Men and individuals of Puerto Rican background had the most min/day of leisure-time MVPA (30.3 and 30.2, respectively). Individuals of Puerto Rican and Dominican background had the most min/day of transportation-related PA (48.7 and 39.7, respectively). Individuals of Mexican and Central American background had the most min/day of work-related MVPA (90.7 and 93.2, respectively). Conclusions Among Hispanics/Latinos, self-reported data provided information on the type of PA and helped explain variability identified from accelerometer-assessed PA. These findings highlight variability in PA among Hispanics from diverse ethnic backgrounds.

A faith-based intervention was effective in increasing MVPA and decreasing body mass index among participants. Process analyses showed the value of program attendance and motivational interviewing calls.

Most interventions targeted physical activity and/or diet behavioral modification in Latinas and were led by bicultural/bilingual professionals. Potential key intervention settings include community clinics/centers and churches. Although there was limited literature on obesity treatment interventions for U.S. Latinos, the review findings provide valuable insight to researchers and practitioners involved in obesity treatment for U.S. Latino adults.

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 churches were randomly assigned to either the physical activity intervention or cancer screening comparison condition (approximately 27 women per church). In both conditions, promotoras from each church intervened at the individual- (e.g., beliefs), interpersonal- (e.g., social support), and environmental- (e.g., park features and access to health care) levels to affect change on target behaviors. Measurements The study’s primary outcome is min/wk of moderate-to-vigorous physical activity (MVPA) at baseline and 12 and 24 months following implementation of intervention activities. We enrolled 436 Latinas (aged 18–65 years) who engaged in less than 250 min/wk of MVPA at baseline as assessed by accelerometer, attended church at least four times per month, lived near their church, and did not have a health condition that could prevent them from participating in physical activity. Participants were asked to complete measures assessing physical activity and cancer screening as well as their correlates at 12- and 24-months. Summary Findings from the current study will address gaps in research by showing the long term effectiveness of multi-level faith-based interventions promoting physical activity and cancer screening among Latino communities.

BackgroundCancer screening in the USA is suboptimal, particularly for individuals living in vulnerable communities. This study aimed to understand how rurality and racial segregation are independently and interactively associated with cancer screening and cancer fatalism.MethodsWe used data from a nationally representative sample of adults (n=17 736) from National Cancer Institute’s Health Information National Trends Survey, 2011–2017, including cancer screening (colorectal, breast, cervical, prostate) among eligible participants and cancer fatalism. These data were linked to county-level metropolitan status/rurality (US Department of Agriculture) and racial segregation (US Census). We conducted multivariable analyses of associations of geographic variables with screening and fatalism.ResultsBreast cancer screening was lower in rural (92%, SE=1.5%) than urban counties (96%, SE=0.5%) (adjusted OR (aOR)=0.52, 95% CI 0.31 to 0.87). Colorectal cancer screening was higher in highly segregated (70%, SE=1.0%) than less segregated counties (65%, SE=1.7%) (aOR=1.28, 95% CI 1.04 to 1.58). Remaining outcomes did not vary by rurality or segregation, and these variables did not interact in their associations with screening or fatalism.ConclusionSimilar to previous studies, breast cancer screening was less common in rural areas. Contrary to expectations, colorectal cancer screening was higher in highly segregated counties. More research is needed on the influence of geography on cancer screening and beliefs, and how access to facilities or information may mediate these relationships.
