Cost analysis of the built environment: the case of bike and pedestrian trials in Lincoln, Neb.

We estimated the annual cost of bike and pedestrian trails in Lincoln, Neb, using construction and maintenance costs provided by the Department of Parks and Recreation of Nebraska. We obtained the number of users of 5 trails from a 1998 census report. The annual construction cost of each trail was calculated by using 3%, 5%, and 10% discount rates for a period of useful life of 10, 30, and 50 years. The average cost per mile and per user was calculated. Trail length averaged 3.6 miles (range = 1.6-4.6 miles). Annual cost in 2002 dollars ranged from 25,762 to 248,479 (mean = 124,927; median = 171,064). The cost per mile ranged from 5735 to 54,017 (mean = 35,355; median = 37,994). The annual cost per user was 235 (range = 83-592), whereas per capita annual medical cost of inactivity was 622. Construction of trails fits a wide range of budgets and may be a viable health amenity for most communities. To increase trail cost-effectiveness, efforts to decrease cost and increase the number of users should be considered.

Urban sprawl and risk for being overweight or obese.

OBJECTIVES: I examined the association between urban sprawl and the risk for being overweight or obese among US adults. METHODS: A measure of urban sprawl in metropolitan areas was derived from the 2000 US Census; individual-level data were obtained from the Behavioral Risk Factor Surveillance System. I used multilevel analysis to assess the association between urban sprawl and obesity. RESULTS: After I controlled for gender, age, race/ethnicity, income, and education, for each 1-point rise in the urban sprawl index (0-100 scale), the risk for being overweight increased by 0.2% and the risk for being obese increased by 0.5%. CONCLUSIONS: The current obesity epidemic has many causes, but there is an association between urban sprawl and obesity.

Walking and bicycling: an evaluation of environmental audit instruments.

PURPOSE: This paper reviews existing environmental audit instruments used to capture the walkability and bikability of environments. The review inventories and evaluates individual measures of environmental factors used in these instruments. It synthesizes the current state of knowledge in quantifying the built environment. The paper provides health promotion professionals an understanding of the essential aspects of environments influencing walking and bicycling for both recreational and transportation purposes. It serves as a basis to develop valid and efficient tools to create activity-friendly communities. DATA SOURCES: Keyword searches identified journal articles from the computer-based Academic Citation Databases, including the National Transportation Library, the Web of Science Citation Database, and MEDLINE. Governmental publications and conference proceedings were also searched. STUDY INCLUSION AND EXCLUSION CRITERIA: All instruments to audit physical environments have been included in this review, considering both recreation- and transportation related walking and bicycling. Excluded are general methods devised to estimate walking and cycling trips, those used in empirical studies on land use and transportation, and research on walking inside buildings. DATA EXTRACTION METHODS: Data have been extracted from each instrument using a template of key items developed for this review. The data were examined for quality assurance among three experienced researchers. DATA SYNTHESIS: A behavioral model of the built environment guides the synthesis according to three components: the origin and destination of the walk or bike trip, the characteristics of the road traveled, and the characteristics of the areas surrounding the trip's origin and destination. These components, combined with the characteristics of the instruments themselves, lead to a classification of the instruments into the four categories of inventory, route quality assessment, area quality assessment, and approaches to estimating latent demand for walking and bicycling. Furthermore, individual variables used in each instrument to measure the environment are grouped into four classes: spatiophysical, spatiobehavioral, spatiopsychosocial, and policy-based. MAJOR CONCLUSIONS: Individually, existing instruments rely on selective classes of variables and therefore assess only parts of built environments that affect walking and bicycling. Most of the instruments and individual measures have not been rigorously tested because of a lack of available data on walking and bicycling and because of limited research budgets. Future instrument development will depend on the acquisition of empirical data on walking and bicycling, on inclusion of all three components of the behavioral model, and on consideration of all classes of variables identified.

Reliability and validity of two instruments designed to assess the walking and bicycling suitability of sidewalks and roads.

PURPOSE: Public health professionals hypothesize that when community environments provide suitable walking and bicycling conditions, community members will be more active. Measurement indicators and assessment instruments are needed to evaluate suitability. This study determined the reliability and validity of two instruments to assess the suitability of sidewalks for walking and roads for bicycling. METHODS: Two data collectors used walking and bicycling suitability assessment instruments to collect data on 31 road segments. In addition, three transportation experts used a 7-point Likert response system to subjectively evaluate walking and bicycling conditions for the same segments. Intraclass correlations determined the reliability of each assessment instrument and the reliability of the Likert response system. Pearson correlations (research staff assessments with expert assessments) were calculated to determine the criterion-related validity of the suitability measures. RESULTS: Intercoder reliability (intraclass) correlations for the walking and bicycling assessment instruments were r = .79 and .90, respectively. Intercoder reliability of the experts' Likert response system was r = .73 for the walking form and r = .77 for the bicycling form. Criterion-related validity (Pearson) correlations for the walking and bicycling assessment instruments were r = .58 and .62, respectively. CONCLUSION: Although some variables have lower reliability and validity than is ideal, the walking and bicycling suitability assessment instruments appear promising as instruments for community members and professionals to systematically assess key aspects of the physical environment.

Relationship between urban sprawl and physical activity, obesity, and morbidity.

PURPOSE: To determine the relationship between urban sprawl, health, and health-related behaviors. DESIGN: Cross-sectional analysis using hierarchical modeling to relate characteristics of individuals and places to levels of physical activity, obesity, body mass index (BMI), hypertension, diabetes, and coronary heart disease. SETTING: U.S. counties (448) and metropolitan areas (83). SUBJECTS: Adults (n = 206,992) from pooled 1998, 1999, and 2000 Behavioral Risk Factor Surveillance System (BRFSS). MEASURES: Sprawl indices, derived with principal components analysis from census and other data, served as independent variables. Self-reported behavior and health status from BRFSS served as dependent variables. RESULTS: After controlling for demographic and behavioral covariates, the county sprawl index had small but significant associations with minutes walked (p = .004), obesity (p < .001), BMI (p = .005), and hypertension (p = .018). Residents of sprawling counties were likely to walk less during leisure time, weigh more, and have greater prevalence of hypertension than residents of compact counties. At the metropolitan level, sprawl was similarly associated with minutes walked (p = .04) but not with the other variables. CONCLUSION: This ecologic study reveals that urban form could be significantly associated with some forms of physical activity and some health outcomes. More research is needed to refine measures of urban form, improve measures of physical activity, and control for other individual and environmental influences on physical activity, obesity, and related health outcomes.

Chart tracking systems: prerequisite to medical records automation.

In summary, automation of chart tracking is the place to begin full-scale medical record automation. Its collected data provides the framework for design and implementation of other systems, frees resources to use data to best advantage, and allows employees to make a comfortable transition from manual methods to computerized charts. A properly designed tracking system is the first step on the path to the electronic medical record.
