Melanin-concentrating hormone receptor 1 polymorphisms are associated with components of energy balance in the CODING study

submitted by: bfontain
BACKGROUND: The melanin-concentrating hormone receptor 1 (MCHR1) is a G protein-coupled receptor that regulates energy balance and body composition in animal models. Inconsistent effects of MCHR1 polymorphisms on energy homeostasis in humans may partly be attributable to environmental factors. OBJECTIVES: We examined the effect of 4 single nucleotide polymorphisms (rs133073, rs133074, rs9611386, and rs882111) in the MCHR1 gene on body composition as well as energy-related lifestyle...

Sitting-Time, Physical Activity, and Depressive Symptoms in Mid-Aged Women

submitted by: jannique.van.uffelen
Background: Associations of sitting-time and physical activity with depression are unclear. Purpose: To examine concurrent and prospective associations between both sitting-time and physical activity with prevalent depressive symptoms in mid-aged Australian women. Methods: Data were from 8950 women, aged 50–55 years in 2001, who completed mail surveys in 2001, 2004, 2007, and 2010. Depressive symptoms were assessed using the Center for Epidemiological Studies Depression questionnaire....

Active Travel to Work and Cardiovascular Risk Factors in the United Kingdom

submitted by: samwong
Background: Increasing active travel (walking, cycling, public transport) is increasingly seen as integral to strategies to raise physical activity levels. Purpose: This study examined (1) sociodemographic correlates of active travel to work and (2) associations between active travel and cardiovascular risk factors in the United Kingdom (UK). Methods: Data come from Understanding Society, a nationally representative survey of UK residents in 2009/2011, analyzed in 2012. Multinomial...

Walk Scores and Transit Scores and Walking in the Multi-Ethnic Study of Atherosclerosis

submitted by: Jahirsch
Background: Walk Scores and Transit Scores are open-source measures of the neighborhood built environment to support walking (“walkability”) and access to transportation. Purpose: To investigate associations of Street Smart Walk Score and Transit Score with selfreported transport and leisure walking using data from a large multicity and diverse populationbased sample of adults. Methods: Data from a sample of 4552 residents of Baltimore MD, Chicago IL, Forsyth County NC, Los Angeles...

School-Day and Overall Physical Activity Among Youth

submitted by: MichaelLong
Background: Increasing school-day physical activity through policy and programs is commonly suggested to prevent obesity and improve overall child health. However, strategies that focus on school-day physical activity may not increase total physical activity if youth compensate by reducing physical activity outside of school. Purpose: Objectively measured, nationally representative physical activity data were used to test the hypothesis that higher school-day physical activity is...

The Stanford Healthy Neighborhood Discovery Tool: A Computerized Tool to Assess Active Living Environments

submitted by: mbuman
Background: The built environment can influence physical activity, particularly among older populations with impaired mobility. Existing tools to assess environmental features associated with walkability are often cumbersome, require extensive training, and are not readily available for use by community residents. Purpose: This project aimed to develop and evaluate the utility of a computerized, tablet-based participatory tool designed to engage older residents in identifying neighborhood...

Objective Assessment of Obesogenic Environments in Youth: Geographic Information System Methods and Spatial Findings from the Neighborhood Impact on Kids Study

submitted by: Lawrence Frank
Background GIS-based walkability measures designed to explain active travel fail to capture “playability” and proximity to healthy food. These constructs should be considered when measuring potential child obesogenic environments. Purpose The aim of this study was to describe the development of GIS-based multicomponent physical activity and nutrition environment indicators of child obesogenic environments in the San Diego and Seattle regions. Methods Block group–level...

The Faith, Activity, and Nutrition Program: A Randomized Controlled Trial in African-American Churches

submitted by: kinnardd
Background: Faith-based interventions hold promise for promoting health in ethnic minority populations. To date, however, few of these interventions have used a community-based participa- tory research (CBPR) approach, have targeted both physical activity and healthy eating, and have focused on structural changes in the church. Purpose: To report the results of a group randomized CBPR intervention targeting physical activity and healthy eating in African-American churches. Design:...
