To evaluate the growing literature on the built environment and physical activity/obesity, we conducted a review of review papers. Through a systematic search, we identified 36 reviews that met the inclusion criteria and evaluated these reviews based on key information provided, review methodology, and specificity regarding measurement. We also analyzed(More)
We examined prospectively whether persons who perceive their objectively measured high walkable environment as low walkable decrease their walking more and gain more weight than those with matched perceptions. Walkability was measured objectively using GIS. Corresponding perceptions were collected using the Neighborhood Environment Walkability Scale from(More)
PURPOSE To examine if a mass media campaign influenced walking differently in people in different physical environments. DESIGN Quasi-experimental study. Setting . Wheeling, West Virginia. PARTICIPANTS Random sample of adults age 50 to 65 years, response rate: 72.1% (n  =  719 in intervention community, n  =  753 in comparison community). INTERVENTION(More)
In older adults the relationships between health, fall-related risk factors, perceived neighborhood walkability, walking behavior and intervention impacts are poorly understood. To determine whether: i) health and fall-related risk factors were associated with perceptions of neighborhood walkability; ii) perceived environmental attributes, and fall-related(More)
IMPORTANCE Few studies have examined how different proportions of moderate and vigorous physical activity affect health outcomes. OBJECTIVE To examine whether the proportion of total moderate to vigorous activity (MVPA) that is achieved through vigorous activity is associated with all-cause mortality independently of the total amount of MVPA. DESIGN,(More)
BACKGROUND Over the last few years an increasing number of studies investigating the association between the physical environment and physical activity have been published. Many reviews have also summarized this emerging body of research, and such review papers are frequently used by public health policymakers and researchers themselves to inform decision(More)
BACKGROUND Objective and self-reported physical environmental attributes have been related to physical activity. PURPOSE We examined the characteristics of adults who are resident in objectively identified high walkable neighborhoods but whose perceptions of neighborhood attributes are not concordant with objective attributes relating to high walkability.(More)
UNLABELLED BACKGROUND Neighborhood walkability has been associated with physical activity in several studies. However, as environmental correlates of physical activity may be context specific, walkability parameters need to be investigated separately in various countries and contexts. Furthermore, the mechanisms by which walkability affects physical(More)
To reverse the global epidemic of physical inactivity that is responsible for more than 5 million deaths per year, many groups recommend creating "activity-friendly environments." Such environments may have other benefits, beyond facilitating physical activity, but these potential co-benefits have not been well described. The purpose of the present paper is(More)
BACKGROUND Driving is a common part of modern society, but its potential effects on health are not well understood. PURPOSE The present cross-sectional study (n = 37,570) examined the associations of driving time with a series of health behaviors and outcomes in a large population sample of middle-aged and older adults using data from the Social,(More)
