Physical inactivity is one of the most important public health issues in the U.S. and internationally. Increasingly, links are being identified between various elements of the physical-or built-environment and physical activity. To understand the impact of the built environment on physical activity, the development of high-quality measures is essential.(More)
BACKGROUND Researchers and policymakers increasingly identify active living-including walking and bicycling for travel and recreation-as a potential strategy to increase rates of physical activity in the United States. Understanding the impact of the built environment on physical activity levels requires reliable methods to measure potentially relevant(More)
OBJECTIVE To examine neighbourhood food environments, adolescent nutrition and weight status. DESIGN Cross-sectional, observational study. SETTING Minneapolis/St. Paul metropolitan region, Minnesota, USA. SUBJECTS A total of 349 adolescents were recruited to the study. Participants completed 24 h dietary recalls and had their weight and height(More)
The purpose of this study was to explore how exposure to alcohol outlets (around home and school) influenced alcohol use among 242 high-school students (mean age 16.4, 48.8% male, 93.4% White). Results found no relationship between alcohol outlet exposure, using a measure of both distance to and density around students' homes and schools, and alcohol use.(More)
BACKGROUND Inter-rater reliability is an important element of environmental audit tools. This paper presents results of reliability tests of the Irvine-Minnesota Inventory, an extensive audit tool aimed at measuring a broad range of built environment features that may be linked to active living. METHODS Inter-rater reliability was measured by percentage(More)
BACKGROUND Few studies have addressed the potential influence of neighborhood characteristics on adolescent obesity risk, and findings have been inconsistent. PURPOSE Identify patterns among neighborhood food, physical activity, street/transportation, and socioeconomic characteristics and examine their associations with adolescent weight status using(More)
BACKGROUND Obesity researchers increasingly use geographic information systems to measure exposure and access in neighborhood food and physical activity environments. This paper proposes a network buffering approach, the "sausage" buffer. This method can be consistently and easily replicated across software versions and platforms, avoiding problems with(More)
A growing body of health and policy research suggests residential neighborhood density and street connectivity affect walking and total physical activity, both of which are important risk factors for obesity and related chronic diseases. The authors report results from their methodologically novel Twin Cities Walking Study; a multilevel study which examined(More)
BACKGROUND The purpose of this study was to determine 1) the test-retest reliability of adult accelerometer-measured physical activity, and 2) how data processing decisions affect physical activity levels and test-retest reliability. METHODS 143 people wore the ActiGraph accelerometer for 2 7-day periods, 1 to 4 weeks apart. Five algorithms, varying(More)
This article examines the influence of the neighborhood environment on blood profiles, percent body fat, blood pressure, and the metabolic syndrome (MetS) in adolescents. One hundred and eighty-eight adolescents (10-16 yr) agreed to have a fasting blood sample drawn in addition to measures of weight, height, percent fat, and blood pressure. A MetS cluster(More)
