Personal Automobile Dependency
-Car dependency in the U.S is at its tops -The average number of cars per household is 2.1 cars -By the age of 20 most young adults own or have owned a car
Measuring the Built Environment: direct method/strength /weakness
-Direct Methods • Involve the use of in-person audits of the environment by trained observers • Pedestrian Environment Data Scan (PEDS) • Goods and Services (GASI) -Strengths • Objective measure, trained observers collect data, accurate measure of environment - Weaknesses • Time consuming, observer fatigue
Accessibility
-Ease of travel to and from a physical activity facility -Ease of use of a particular physical activity resource -Often used interchangeably with Usability Examples: Little traffic to get to facility No lines to wait in to enter Equipment is easy to set up and use
Parks and Open Spaces
-Environmental Benefits - Trees reduce air pollution -Moderate temperature -Economic Benefits -Increase property values -Increase community business -Puts money back into the community
Home Exercise Equipment
-Equipment that can be used for physical activity or exercise in a home setting Examples: Treadmill Stationary Bike Exercise Videos Team Sports equipment Running Shoes
Safety
-Freedom from danger, risk, or injury -Can act as a motivator or a barrier to physical activity -Motivators - personal safety, away from cars and traffic -Barriers - crime, traffic, fear of dogs/Wolves, lighting, no one else around, etc.
Rural Communities
-Higher levels of obesity -More poverty, medically underserved, lower educational levels -Feelings of isolation -Few sidewalks and no shopping malls -Fewer resources
Measuring the Built Environment: indirect method/strength/weakness
-Indirect Methods • Aggregate data - data combined from several measures • SES- a measure of economic and social ranking • US Census • US Geological Survey of land use and land cover • Geographic Information System (GIS) • Computer based method stores, analyses, and combines geographic information such as aerial phots, land use, parks, schools, streets -Strength • time efficient -Weakness • data sources may not be up to date as those obtained by direct observation
Measuring the Built Environment: intermediate method/strength/weakness
-Intermediate Methods • Neighborhood Environment Walkability Scale (NEWS) • Self Report - residents provide information about - types of residences, access to services, stores and facility, safety, aesthetic, streets and intersections • Databases (Internet and marketing) -Strengths • Time efficient, less staff burden -Weaknesses • Bias on participant's part • Incomplete/inaccurate databases
Health Benefits: walking
-Lead to increased energy expenditure -Weight loss -Improved fitness -Increase lipoprotein concentration (women) -Reduced risk of osteoporosis
Physical Activity Association to Obesity
-Physical Activity + Exercise = Physical Fitness - FITT Principle -Principle of Progression -Stress/Rest Principle
Future Implications
-Promoting trails, parks and other public facilities may lead to an increase in physical activity in our communities -Influence changes in policy -create more safe, high quality resources for people of all economic levels - make resources already available more attractive to potential physical activity seekers
Urban Communities
-Urban planning has created more sidewalks, bikeways, shopping malls, etc. - Greater access & closer proximity -More frequent use of PA resources
measuring the built environment : 3 categories
-self-report methods -geographic information systems-based measures (GIS-based measures) - observational assessment method

Measuring Facilities: Subjective Measures
Measure perceptions or self-reports of accessibility, proximity, safety, and quality of resources Examples : questionnaires surveys
Walkability: (Mixed income, mixed use:Nearby schools and workplaces)
Mixed income, mixed use: Housing is provided for everyone who works in the neighborhood: young and old, single and families, rich and poor. Businesses and residences are located near each other. Nearby schools and workplaces: Schools and workplaces are close enough that most residents can walk from their homes.
Stair Climbing
Mortality Rate 13.6= <10 Storeys Climbed (per wk) Mortality Rate 13.5 = 10< 20 Storeys Climbed (per wk) Mortality Rate 10= 20-<25 Storeys Climbed (per wk) Mortality Rate 9.5= 25+Storeys Climbed (per wk)
Burden on Natural Resources
Nearly 1 billion gallons of additional fuel per year can be attributed to the average weight gain between 1960 and 2002 of people living in the United States
Walkability: Parks and public space
Parks and public space: There are plenty of public places to gather and play
Proximity
Perceived or objectively measured distance of physical activity resources to an individual Examples: -Distance (in miles) of gym from your home (objective measure) -Approximate number of minutes it takes to get to the gym from your home (perceived)
Amenities
Specific features of recreation facilities that add comfort or convenience to users and influence them to partake in physical activity Examples: Restrooms Benches Street lights
Health Benefits: Using Stairs as Transportation
Take the stairs instead of the escalator Net on pound fat loss annually 10 min/day of stairs for 8 wks = 30 min/day walking 24 wks

Density
The quantity of people, households, or employment in a given area -Population per square mile -Number of jobs per square mile World Population = 7.7 Billion • USA = 327 million • Texas = 29.4 million • Metro Houston = 7 million
Walkability: A Center
Walkable neighborhoods have a discernable center, whether it's a shopping district, a main street, or a public space.
Children and Adolescents and Obesity
Why? -Perhaps less access to close, safe physical activity resources
what is active transportation
a means of traveling from one location to another by way of some kind of individual physical activity
how does direct assessment differ from indirect assessment of a neighborhood
direct environment assessment methods to measure built environment involve the use of in-person audits to measure the environment while indirect methods rely on reports from residents
