ABSTRACT Little is known about the patterning of neighborhood characteristics, beyond the basic urban, rural, suburban trichotomy, and its impact on physical activity (PA) and overweight.
Nationally representative data (National Longitudinal Study of Adolescent Health, 1994-1995, n = 20,745) were collected. Weight, height, PA, and sedentary behavior were self-reported. Using diverse measures of the participants' residential neighborhoods (e.g., socioeconomic status, crime, road type, street connectivity, PA recreation facilities), cluster analyses identified homogeneous groups of adolescents sharing neighborhood characteristics. Poisson regression predicted relative risk (RR) of being physically active (five or more bouts/week of moderate to vigorous PA) and overweight (body mass index equal or greater than the 95th percentile, Centers for Disease Control and Prevention/National Center for Health Statistics growth curves).
Six robust neighborhood patterns were identified: (1) rural working class; (2) exurban; (3) newer suburban; (4) upper-middle class, older suburban; (5) mixed-race urban; and (6) low-socioeconomic-status (SES) inner-city areas. Compared to adolescents living in newer suburbs, those in rural working-class (adjusted RR[ARR] = 1.38, 95% confidence interval [CI] = 1.13-1.69), exurban (ARR = 1.30, CI = 1.04-1.64), and mixed-race urban (ARR = 1.31, CI = 1.05-1.64) neighborhoods were more likely to be overweight, independent of individual SES, age, and race/ethnicity. Adolescents living in older suburban areas were more likely to be physically active than residents of newer suburbs (ARR = 1.11, CI = 1.04-1.18). Those living in low-SES inner-city neighborhoods were more likely to be active, though not significantly so, compared to mixed-race urban residents (ARR = 1.09, CI = 1.00-1.18).
These findings demonstrate disadvantageous associations between specific rural and urban environments and behavior, illustrating important effects of the neighborhood on health and the inherent complexity of assessing residential landscapes across the United States. Simple classical urban-suburban-rural measures mask these important complexities.

    ABSTRACT: Background: Rural children are at greater risk for physical inactivity and obesity than their urban counterparts. The study purpose was to identify the perceived environmental factors in the home, school, and community that support physical activity among rural children. Methods: A concurrent mixed-methods study involving 99 parent-child (ages 6-11 years) dyads and 17 teachers from four rural communities was conducted in 2007. Qualitative methods included focus group (child only) and PhotoVOICE (parents, teachers) sessions. Quantitative methods included a survey (parent), accelerometry (child), and Geographic Information Systems analysis. All data were merged and results compared. Agreement from all three populations (children, parents, and teachers) provided the highest level of evidence followed by agreement among two populations, and then evidence from each population independently. Results: Within the home, physical activity opportunities include parenting practices (e.g. logistical support), the presence of siblings, and availability of physical activity equipment. At school, opportunities include age-appropriate recreation equipment, adequate recess and physical education time, policies to support physical activity and physical education programming, and school location. In the community, access to destinations (e.g. living close to town center), park and recreation availability (especially indoor opportunities), and resolution of perceived safety issues (e.g. wild or roaming animals) would enhance children's physical activity in rural settings. Conclusions: Opportunities for increasing rural children's physical activity exist. More research, interventions, and, evaluations on ways to promote physical activity in diverse rural settings is needed.

    ABSTRACT: Au cours des deux dernières décennies, un nombre important d’études aux États-Unis, au Canada et en Europe ont tenté d’identifier les liens existants entre les caractéristiques des quartiers et les comportements antisociaux des enfants et des adolescents. Malgré l’abondance des travaux, la question du choix de l’échelle spatiale a fait l’objet de peud’attention. D’autres études suggèrent que les caractéristiques des quartiers pourraient jouer le rôle de variables potentiellement modératrices sur les facteurs de risque traditionnellement observés. De plus, les études sur les effets de quartier dans une perspective longitudinale ne sont pas nombreuses. Une dernière contribution à l’avancement des connaissances de notre thèse est reliée au choix du territoire d’étude, car, à notre connaissance, très peu de recherches empiriques ont été réalisées sur la thématique des effets de quartier sur le développement de comportements antisociaux au Québec et plus particulièrement à Montréal. Notre thèse tente de combler ces lacunes.
