Walking, both for leisure and for travel/errands, counts toward meeting physical activity recommendations. Both social and physical neighborhood environmental features may encourage or inhibit walking. This study examined social capital, perceived safety, and disorder in relation to walking behavior among a population of low-income housing residents. Social and physical disorder were assessed by systematic social observation in the area surrounding 20 low-income housing sites in greater Boston. A cross-sectional survey of 828 residents of these housing sites provided data on walking behavior, socio-demographics, and individual-level social capital and perceived safety of the areas in and around the housing site. Community social capital and safety were calculated by aggregating individual scores to the level of the housing site. Generalized estimating equations were used to estimate prevalence rate ratios for walking less than 10 min per day for a) travel/errands, b) leisure and c) both travel/errands and leisure. 21.8% of participants walked for travel/errands less than 10 min per day, 34.8% for leisure, and 16.8% for both kinds of walking. In fully adjusted models, those who reported low individual-level social capital and safety also reported less overall walking and less walking for travel/errands. Unexpectedly, those who reported low social disorder also reported less walking for leisure, and those who reported high community social capital also walked less for all outcomes. Physical disorder and community safety were not associated with walking behavior. For low-income housing residents, neighborhood social environmental variables are unlikely the most important factors in determining walking behavior. Researchers should carefully weigh the respective limitations of subjective and objective measures of the social environment when linking them to health outcomes.

ABSTRACT: Non-significant findings are reported in approximately half of the studies examining correlations between environmental characteristics and walking. One reason could involve spatial incongruence in which environments examined are not necessarily the ones where the behavior occurred. To study correlates of perceived neighborhood size and the congruence between perceived and investigator defined neighborhood areas. Door-to-door surveys were conducted in 12 U.S. Census block groups with 18-87 year old adults. Participants were asked about exercise participation and to draw a map representing their neighborhood. Geographical information software was used to construct maps, calculate neighborhood areas, and analyze congruence. Neighborhood sizes perceived by women were smaller than those perceived by men and positively related to min/wk of biking and education. Education and age were negatively and perceived neighborhood support for exercise was positively associated with perceived neighborhood size in men. Approximately 90% of perceived neighborhood areas overlapped with neighborhood areas defined by circles with 1200 m radii from participants' homes. Several individual characteristics including exercise are associated with perceptions of neighborhood size. Standard investigator-defined neighborhoods using a 1200 m radius (15 min walk) from a participant's home is sufficient to capture a majority of perceived neighborhood areas.Journal of Physical Activity and Health 04/2014; 12(2).

ABSTRACT: Objective To analyse whether an individual's neighbourhood influences the uptake of weight management strategies and if there is an interaction between individual socio-economic status (SES) and neighbourhood deprivation.MethodologyData were collected from the Yorkshire Health Study (2010-2012) for 27 806 individuals on the use of the following weight management strategies; 'slimming clubs', 'healthy eating', 'increasing exercise' and 'controlling portion size'. A multi-level logistic regression was fit to analyse the use of these strategies, controlling for age, sex, body mass index, education, neighbourhood deprivation and neighbourhood population turnover (a proxy for neighbourhood social capital). A cross-level interaction term was included for education and neighbourhood deprivation. Lower Super Output Area was used as the geographical scale for the areal unit of analysis.ResultsSignificant neighbourhood effects were observed for use of 'slimming clubs', 'healthy eating' and 'increasing exercise' as weight management strategies, independent of individual- and area-level covariates. A significant interaction between education and neighbourhood deprivation was observed across all strategies, suggesting that as an area becomes more deprived, individuals of the lowest education are more likely not to use any strategy compared to those of the highest education.Conclusions Neighbourhoods modify/amplify individual disadvantage and social inequalities, with individuals of low education disproportionally affected by deprivation. It is important to include neighbourhood-based explanations in the development of community based policy interventions to help tackle obesity.International Journal of Obesity accepted article preview online, 4 August 2014; doi:10.1038/ijo.2014.152.International journal of obesity (2005) 08/2014; 39(3).

ABSTRACT: Acculturation may influence health behaviors, yet mechanisms underlying its effect are not well understood. In this study, we describe relationships between acculturation and health behaviors among low-income housing residents, and examine whether these relationships are mediated by social and contextual factors. Residents of 20 low-income housing sites in the Boston metropolitan area completed surveys that assessed acculturative characteristics, social/contextual factors, and health behaviors. A composite acculturation scale was developed using latent class analysis, resulting in four distinct acculturative groups. Path analysis was used to examine interrelationships between acculturation, health behaviors, and social/contextual factors, specifically self-reported social ties, social support, stress, material hardship, and discrimination. Of the 828 respondents, 69% were born outside of the U.S. Less acculturated groups exhibited healthier dietary practices and were less likely to smoke than more acculturated groups. Acculturation had a direct effect on diet and smoking, but not physical activity. Acculturation also showed an indirect effect on diet through its relationship with material hardship. Our finding that material hardship mediated the relationship between acculturation and diet suggests the need to explicate the significant role of financial resources in interventions seeking to promote healthy diets among low-income immigrant groups. Future research should examine these social and contextual mediators using larger, population-based samples, preferably with longitudinal data.Social Science & Medicine 10/2014; DOI:10.1016/j.socscimed.2014.10.034 · 2.89 Impact Factor
