The prevalence of obesity has become a primary risk factor for adolescents’ health, which is an essential in poverty reduction and sustainable development. Physical activity can help adolescents reduce keep healthy body mass index (BMI). We analyze the 2010 National Youth Activity Nutrition Survey (NYPANS) U.S. school students from 9th to 12th grades (aging 12 18). A latent variable analysis ex...

OBJECTIVE The purpose of this cross-sectional study was to establish neighborhood built environment correlates of adiposity as measured by dual x-ray absorptiometry (DXA). The utility and methodological gains of using this measure for built environment research was further investigated by comparing model fit across parallel models on BMI z-scores and waist circumference. METHODS Pre-existing ...

Objectives To identify the associations of characteristics of the neighborhood environment with substance abuse among clients receiving treatment for drug abuse in Thailand. Methods A cross-sectional study was conducted of 1128 drug addicts from 28 neighborhoods who were receiving treatment at all 7 compulsory drug detention centers in Thailand. A trained interviewer conducted structured inte...

BACKGROUND Self-reported and objectively-determined neighborhood built characteristics are associated with physical activity, yet little is known about their combined influence on walking. This study: 1) compared self-reported measures of the neighborhood built environment between objectively-determined low, medium, and high walkable neighborhoods; 2) estimated the relative associations between...

BACKGROUND Physical activity is important to children's physical health and well-being. Many factors contribute to children's physical activity, and the built environment has garnered considerable interest recently, as many young children spend much of their time in and around their immediate neighborhood. Few studies have identified correlates of children's activity in specific locations. This...

INTRODUCTION Built environment attributes have been linked to cardiovascular disease (CVD) risk. Therefore, identifying built environment attributes that are associated with CVD risk is relevant for facilitating effective public health interventions. OBJECTIVE To conduct a systematic review of literature to examine the influence of built environmental attributes on CVD risks. DATA SOURCE Mu...

The present study explored whether perceived neighborhood environmental attributes associated with physical activity differ by neighborhood income. Adults aged 20-65 years (n=2199; 48% female; mean age=45 years; 26% ethnic minority) were recruited from 32 neighborhoods from the Seattle, WA and Baltimore, MD regions that varied in objectively measured walkability and neighborhood income. Perceiv...

Particle filter based on particle swarm optimization algorithm (PSO-PF) is not precise and trapping in local optimum easily, it is not able to satisfy the requirement of advanced integrated navigation system. In order to solve these problems, a novel particle filter algorithm based on dynamic neighborhood population adaptive particle swarm optimization (DPSO-PF) is presented in this paper. This...

BACKGROUND It is well documented in the literature that low socioeconomic status (SES) is associated with lower consumption of healthy foods and that these differences in consumption patterns are influenced by neighborhood food environments. Less understood is the role that SES differences in physical and social aspects of the home food environment play in consumption patterns. METHODS Using ...
