Neighborhood Environment Walkability Scale for Youth (NEWS-Y): Reliability and relationship with physical activity
ABSTRACT To examine the psychometric properties of the Neighborhood Environment Walkability Scale-Youth (NEWS-Y) and explore its associations with context-specific and overall physical activity (PA) among youth.
In 2005, parents of children ages 5-11 (n=116), parents of adolescents ages 12-18 (n=171), and adolescents ages 12-18 (n=171) from Boston, Cincinnati, and San Diego, completed NEWS-Y surveys regarding perceived land use mix-diversity, recreation facility availability, pedestrian/automobile traffic safety, crime safety, aesthetics, walking/cycling facilities, street connectivity, land use mix-access, and residential density. A standardized neighborhood environment score was derived. Self-reported activity in the street and in parks, and walking to parks, shops, school, and overall physical activity were assessed.
The NEWS-Y subscales had acceptable test-retest reliability (ICC range .56-.87). Being active in a park, walking to a park, walking to shops, and walking to school were related to multiple environmental attributes in all three participant groups. Total neighborhood environment, recreation facilities, walking and cycling facilities, and land use mix-access had the most consistent relationships with specific types of activity.
The NEWS-Y has acceptable reliability and subscales were significantly correlated with specific types of youth PA. The NEWS-Y can be used to examine neighborhood environment correlates of youth PA.

ABSTRACT: Neighborhood built environments (BE) include combinations of co-existing stimuli influencing physical activity (PA). Dealing with numerous environmental variables and complexity presents a significant challenge. The current analysis explored whether a range of reported BE features associated with adults' physical activity produced distinct multivariate patterns, and tested whether adults' PA and body mass differed by BE profiles. Participants (20-65 years, 48.2% female, 26% ethnic minority) were recruited between 2002 and 2005 from 32 neighborhoods from Seattle-King County, WA (N=1287) and Baltimore, MD-Washington, DC regions (N=912). Independent Latent Profile Analyses were conducted in each region with 11 environmental variables from the Neighborhood Environment Walkability Scale. Validity of the neighborhood profiles was examined by their relationship to PA (accelerometer-derived moderate-to-vigorous minutes/day, self-reported minutes/week of walking for transportation and leisure) and self-reported BMI using ANCOVA models. Neighborhood profiles for Seattle and Baltimore regions were visually similar, suggesting generalizability. High-walkable recreationally-dense neighborhoods differed significantly from other neighborhood types by as much as 13 MVPA minutes/day, almost 60 minutes/week of walking for transportation, and 75 min/week of leisure-time activity. Neighborhood profiles also differed significantly for BMI. These findings could help identify optimal patterns of environmental attributes that facilitate physical activity and improve weight status.Preventive Medicine 03/2011; 52(5):326-31.

Conference Paper: Impact assessment of organotin chemicals in harbor environments[Show abstract] [Hide abstract]
ABSTRACT: The use of organotin chemicals in antifouling paints is expected to increase as the new polymer-based tins provide exceptionally long protection against fouling for marine vessels. Environmental modeling studies of New York Harbor and Chesapeake Bay were undertaken to determine whether the anticipated increase in use of organotins poses a risk to estuarine biota. The inputs of antifouling toxicant were estimated from vessel traffic data provided by the U.S. Coast Guard. Environmental chemistry parameters were derived generally from previously published reports. The model results indicate that tributyltin toxicants are likely to be transported to the open ocean or decay before significant quantities accumulate in harbor waters or sediments. Water column concentrations, for the harbors studied, are shown not to exceed 5.0 nanograms per liter (ng/l) even with 100 percent of the commercial vessels using organotin antifouling paints. Published studies suggest this level will have no adverse effects on vertebrate estuarine life.OCEANS '85 - Ocean Engineering and the Environment; 12/1985
