Of the 15 studies with BMI measured categorically, three also examined BMI as a continuous variable ( 35 , 43 , 49 ). Activity spaces within metropolitan areas and county-level areas may differ. Trained staff measured heights and weights of all children at baseline and year 3. Read "Advancing Obesity Solutions Through Investments in the Built There is evidence that, in addition to measuring structural aspects of the built environment, measures of the social environment are also important influences on food consumption and activity ( 72 ). A neighborhood walkability scale was developed using measures of residential density, mixed land use, and street connectivity. Research to date has focused on three life stages: childhood, adolescence, and adulthood. CD00 1871). For example, a neighborhood's identity as an ethnic enclave may be determined by the existence of certain key commercial or residential characteristics, by the population composition, or by its identification as such by either insiders or outsiders. Self-reported height and weight were used to compute continuous measures of BMI. Five studies did not include categories of BMI, examining it only as a continuous variable ( 40 , 41 , 46 , 51 , 52 ). The average length of trips in the United States is 6.8 miles (10.9 km), taking residents well beyond the confines of their neighborhoods ( 67 ). Two investigations examining metropolitan indices of sprawl ( 43 , 51 ) found no statistically significant association with obesity. Research on the built environment and obesity among youths could benefit from a stronger consideration of life-course stage in the selection of measures. Understanding the impact of the built environment on obesity may provide information necessary to develop successful community-based prevention efforts ( 29 ). Incorporating more uniform measures of the built environment into future research will aid in the decision of which interventions to pursue (e.g., zoning density increases or removal of mixed-use restrictions) and facilitate the development of policy interventions at the community level. Cross-sectional study of US adults living in county populations of 500,000 or more who participated in the Third National Health and Nutrition Examination Survey (19881994), A composite measure of walkability based on three county-level indicators: 1) the negative of average block size; 2) percentage of all blocks having areas less than 0.01 square miles (0.02 km. For adults, environments of interest might include residential space, work space, and characteristics of the travel environment between work, shopping, and personal business, social, and recreational activities and the residence. Share Although it's easy to point the finger at everyone from Ronald McDonald to Bill Gates, no one entity or factor is specifically to blame for the nation's raging obesity epidemic, according to speakers at the first-ever national conference on obesity and the built environment, held in late May in Washington, D.C. Reasons for this conflicting evidence are unclear but may include differential effects of mixed land use on obesity risk within different racial/ethnic groups. Given the detrimental health consequences of obesity and the rapidly rising rates, successful prevention efforts are urgently needed. No differences found in the average distance to a play space by BMI status (mean distances for obese and nonobese children were 567 m and 571 m, respectively). The many theoretical pathways between the built environment and obesity have necessarily resulted in a diverse range of influences' being conceptualized and measured (see figure 1 ). Travel is thought to be an outgrowth of activities, where in-home and outside activities are both substitutes for and complements of each other. A key principle is that interventions should be most effective when they change the person, the social environment, and built environments and policies. ( 33 ) incorporated young children as well as adolescents, the results were shown for all age groups combined. Fighting Obesity Through the Built Environment - PMC For example, data from the US Census provide inexpensive and easily available measures of some aspects of the built environment. Understanding the mechanisms through which environmental factors may influence obesity will aid in developing future community-level intervention strategies to curb this epidemic. Relations were stronger among Whites than among Blacks. Given the large number of linked trips people make in today's society, destination accessibility is potentially significant in that it affects people's ability to efficiently link trips for different purposes or complete more than one activity at a single stop. Measured height and weight data were used to compute BMI with BMI used continuously in all models. Neighborhood was defined as a -mile (0.4-km) radius around each person's residence. For young children who are unable to obtain their own food, influences on parental food choices for the home, such as the cost of foods, may be a key environmental factor influencing consumption and, in turn, weight gain. Although the use of multilevel modeling methods is an important advancement, there is additional information to be gained by adopting more spatially explicit analytical tools as well. Rates have been rising rapidly over the past two decades among both children and adults ( 1420 ). An estimated 32% of American children are overweight, and physical inactivity contributes to this high prevalence of overweight. Introduction The health of individuals and populations is affected by the environment in which they live. In this study, Using Geographic Information Systems (GIS) to assess the role of the The measure of body weight used in all of the studies was BMI, determined either from self-reported weights and heights ( n = 14) or measured weights and heights ( n = 6). Two measures of the built environment included square miles per fast-food restaurant and population per fast-food restaurant. Attributes of the food and physical activity built - Nature ( 48 ) used them to classify neighborhoods as to their degree of walkability; and Nelson et al. The environment currently favors and facilitates motorized vehicles generally, and private automobiles especially. ( 43 ) used these measures to construct an overall index of sprawl that was later used in three other studies ( 4951 ); Sturm and Datar ( 41 ) and Doyle et al. The investigation by Burdette and Whitaker ( 36 ) included low-income children enrolled in the Women, Infants, and Children program in Cincinnati, Ohio. A systematic review of built environment factors related to physical activity and obesity risk: implications for smart growth urban planning. Proximity to the nearest public play space, measured as the distance (m) from a child's home address to the nearest YMCA. Given the importance of the physical and social contexts of individual behavior and the limited success of individual-based interventions in long-term obesity prevention, more research on the impact of the built environment on obesity is needed. ( 83 ) found that youths in high-poverty neighborhoods lived closer to playgrounds, but on average these playgrounds tended to be less safe than those in neighborhoods of higher socioeconomic status. Ewing et al. The two longitudinal studies within this area of research investigated change in BMI during a 3-year period for children aged 4 and 5 years ( 41 ) and during a 7-year period for adolescents aged 1217 years ( 49 ).

The associations between built and food environments and childhood obesity have been studied extensively. Rated Helpful Answered by bonitaaranha The correct answer is: A. the creation of food deserts. Primarily because of limited data availability, there has been a lack of work on the food environment relative to the physical activity environment. This has also been observed for neighborhoods in Chicago, Illinois ( 84 ). Obesity and the built environment at different urban scales: examining The study evaluated the stability and safety of roads and sidewalks as to whether they encouraged For studies that examined the density of food outlets, area measurements differed.

Cross-sectional survey of 107 residents aged 1865 years recruited from high-walkability (. However, for many environmental influences, other attributes, such as density, may be more important than distance. Conflicting results were evident for the association between land-use mix and risk of obesity. Answer & Explanation Solved by verified expert All tutors are evaluated by Course Hero as an expert in their subject area. Multilevel analytical tools will allow for simultaneous computation of the effects of group-level variables and individual-level variables on outcomes such as BMI. Indices included dimensions of residential density, land-use mix, and street accessibility. Recently, there has been a growing body of evidence linking aspects of the built environment to obesity ( 3352 ). Cross-sectional US study using data from the 2000 BRFSS on 104,084 adults who resided in metropolitan areas. While the study by Liu et al. Sidewalk availability, number and distance to physical activity facilities, mixed land use, intersection density, and slope (average change in elevation) were used as measures of the built environment. Self-reported height and weight were used to compute BMI, and state obesity rates were defined as the percentage of the population with a BMI 30. Studying adolescents in China, Li et al. The more activities available within a given travel time, the better the accessibility of a location. Poor persons, for example, are thought to be more affected by their built environments because their activity spaces are smaller and they are more constrained by lack of transportation and opportunities for mobility. Self-reported height and weight data were used to compute BMI; adults were classified as obese (BMI 30) or nonobese (BMI < 30). Abstract.

Nine studies incorporated at least one of these measures ( 34 , 35 , 37 , 40 , 43 , 46 , 4951 ). These characteristics are considered in more detail below. Travel has been redirected to cars, reducing opportunities for active travel. To us, sustainability is a journey full of possibilities and opportunities to make a difference for the planet -through our own actions and by empowering our ABOs and their customers to . Finally, two studies examined measures relating to transportation ( 37 , 42 ). Food availability was measured as the number of grocery stores, fast-food restaurants, convenience stores, and full-service restaurants per 1,000 persons in each child's ZIP code. The accessibility of activities is thought to be the primary determinant of travel choices, affecting both physical activity and dietary behaviors. However, the association between the natural environment and childhood obesity has received too little scholarly attention. The built, or physical, environment consists of its man-made, constructed components - roads and sidewalks, buildings and houses, parks and plazas, and more. They examined four variables, including average area prices for meats, dairy products, fruits and vegetables, and fast food. Examining racial/ethnic differences in the relation between the built environment and overweight may aid in the development of culturally specific community-level interventions. Within the United States, national guidelines recommend defining childhood overweight status by applying age- and sex-adjusted norms and using percentile cutpoints to classify overweight. The Built Environment: Designing Communities to Promote Physical Seven measures of the built environment were developed at the ZIP code level from US Census and US Geological Survey data. Measured height and weight data were used to compute BMI. Standard definitions were used across adult populations. Besides the physical availability of food outlets, Sturm and Datar ( 41 ) additionally examined the cost of foods within metropolitan areas where children resided. Role of Built Environments in Physical Activity, Obesity, and
