Social capital and the neighborhood alcohol environment

We examine whether neighborhood alcohol outlet density is associated with reduced social capital and whether this relationship is mediated by perceived neighborhood safety. Hierarchical models from a random sample of Los Angeles, CA, and Louisiana residents (N=2,881) from 217 census tracts were utilized. Substantial proportions of the variance in collective efficacy (intraclass correlation coefficient, ICC=16.3%) and organizational participation (ICC=13.8%, median odds ratio=1.99) were attributable to differences between neighborhoods-suggesting that these factors may be influenced by neighborhood-level characteristics. Neighborhood alcohol outlet density was strongly associated with reduced indicators of social capital, and the relationship between collective efficacy and outlet density appears to be mediated by perceived neighborhood safety. Findings support the concept that off-premise alcohol outlets in the neighborhood environment may hinder the development of social capital, possibly through decreased positive social network expansion.     

Secondhand effects of student alcohol use reported by neighbors of colleges: the role of alcohol outlets

This is a study of the secondhand effects of student alcohol use experienced by residents of neighborhoods near college campuses. We examined the relationship of a college's level of binge drinking and the number of alcohol outlets in the immediate area, to lowered quality of neighborhood life through such secondhand effects. Adults from 4661 households in the United States were interviewed through a stratified list-assisted random digit dialing telephone survey. The interview schedule included questions about residents' experiences of secondhand effects of alcohol use such as noise, vandalism or public disturbances. Reports about the quality of neighborhood life provided by respondents residing near colleges were compared with those of respondents who did not live near colleges; and reports of neighbors of colleges with high rates of binge drinking were compared with those of neighbors of colleges with lower rates. The presence of alcohol outlets in these areas was also compared. Residents near colleges and particularly near colleges with heavy episodic drinking reported the presence of more alcohol outlets within a mile. Those neighborhoods were characterized by lower socioeconomic status. Neighbors living near college campuses were more likely to report a lowered quality of neighborhood life through such secondhand effects of heavy alcohol use as noise and disturbances, vandalism, drunkenness, vomiting and urination. A path analysis indicated that the number of nearby alcohol outlets was an important factor mediating the relationship between colleges, especially those with high rates of binge drinking, and such secondhand effects. The results suggest that neighborhood disruptions around colleges due to heavy alcohol use may be reduced by limiting the presence of alcohol outlets in those areas, and the marketing practices that this engenders.     

Neighborhood deprivation and access to fast-food retailing: a national study

BACKGROUND: Obesogenic environments may be an important contextual explanation for the growing obesity epidemic, including its unequal social distribution. The objective of this study was to determine whether geographic access to fast-food outlets varied by neighborhood deprivation and school socioeconomic ranking, and whether any such associations differed to those for access to healthier food outlets. METHODS: Data were collected on the location of fast-food outlets, supermarkets, and convenience stores across New Zealand. The data were geocoded and geographic information systems used to calculate travel distances from each census meshblock (i.e., neighborhood), and each school, to the closest fast-food outlet. Median travel distances are reported by a census-based index of socioeconomic deprivation for each neighborhood, and by a Ministry of Education measure of socioeconomic circumstances for each school. Analyses were repeated for outlets selling healthy food to allow comparisons. RESULTS: At the national level, statistically significant negative associations were found between neighborhood access to the nearest fast-food outlet and neighborhood deprivation (p<0.001) for both multinational fast-food outlets and locally operated outlets. The travel distances to both types of fast food outlet were at least twice as far in the least socially deprived neighborhoods compared to the most deprived neighborhoods. A similar pattern was found for outlets selling healthy food such as supermarkets and smaller food outlets (p<0.001). These relationships were broadly linear with travel distances tending to be shorter in more-deprived neighborhoods. CONCLUSIONS: There is a strong association between neighborhood deprivation and geographic access to fast food outlets in New Zealand, which may contribute to the understanding of environmental causes of obesity. However, outlets potentially selling healthy food (e.g., supermarkets) are patterned by deprivation in a similar way. These findings highlight the importance of considering all aspects of the food environment (healthy and unhealthy) when developing environmental strategies to address the obesity epidemic.     

Neighborhood-level factors and youth violence: giving voice to the perceptions of prominent neighborhood individuals.

Youth violence is a significant public health problem. Although the relationship between neighborhood-level factors and urban youth violence is recognized, the specific mechanisms of this relationship are often unclear. Prominent neighborhood individuals were identified within four select low-income urban neighborhoods in Baltimore City. In-depth interviews were conducted to explore these individuals' perceptions of the relationship between social and structural neighborhood-level factors and urban youth violence. Employment opportunities, local businesses, trash management, vacant housing, and street lighting were perceived as important neighborhood factors influencing young people's experiences. The relationship between these neighborhood characteristics and the local illicit drug market and youth violence is highlighted. Results provide an enhanced understanding of the importance of using a participatory-based research approach and the mechanisms of the relationship between neighborhood-level factors and youth violence. Both are critical components in designing and implementing multilevel youth violence prevention efforts.     

Fear of walking outdoors. A multilevel ecologic analysis of crime and disorder

BACKGROUND: Although a number of studies have tested ecologic models that postulate relationships among social networks, the built environment, and active living, few neighborhood-based studies have considered the role of crime and violence. This study investigates the degree to which individual-level demographic characteristics and neighborhood-level physical and social characteristics are associated with increased fear of crime. METHODS: Data were analyzed in 2007 from a 2005 survey of 901 randomly selected individuals living in 55 neighborhoods in Washington DC. Multilevel ordered logit regression was used to examine associations between individual-level and neighborhood-level characteristics and how often fear of crime prevents a respondent from walking outdoors. RESULTS: Age and female gender were associated with an increase in fear; the percentage of a resident's life spent in the same neighborhood was associated with a decrease in fear. Results of cross-level interactions showed that at the neighborhood level, women were more fearful than men in neighborhoods without violence, but that the difference in fear between men and women shrinks as neighborhood violence increases. Collective efficacy was found to increase fear among black respondents and had no effect on fear among nonblack respondents. CONCLUSIONS: If the study of neighborhoods and active living is to progress and contribute to both etiologic understanding and policy formation, it is essential that theoretical and empirical models consider the impact of violence and fear on walking. Efforts to increase active living in urban neighborhoods that do not account for the impact of crime and fear may fall short of their intended outcomes.     

Neighborhood-Level Factors Associated with Physical Dating Violence Perpetration: Results of a Representative Survey Conducted in Boston, MA

Neighborhood-level characteristics have been found to be associated with different forms of interpersonal violence, but studies of the relationship between these characteristics and adolescent dating violence are limited. We examined 6 neighborhood-level factors in relation to adolescent physical dating violence perpetration using both adolescent and adult assessments of neighborhood characteristics, each of which was aggregated across respondents to the neighborhood level. Data came from an in-school survey of 1,530 public high school students and a random-digit-dial telephone survey of 1,710 adult residents of 38 neighborhoods in Boston. Approximately 14.3% of the youth sample reported one or more acts of physical aggression toward a dating partner in the month preceding the survey. We calculated the odds of past-month physical dating violence by each neighborhood-level factor, adjusting for school clustering, gender, race, and nativity. In our first 6 models, we used the adolescent assessment of neighborhood factors and then repeated our procedures using the adult assessment data. Using the adolescent assessment data, lower collective efficacy (AOR = 1.95, 95% CI = 1.09–3.52), lower social control (AOR = 1.92, 95% CI = 1.07–3.43), and neighborhood disorder (AOR = 1.19, 95% CI = 1.05–1.35) were each associated with increased likelihood of physical dating violence perpetration. However, when we used the adult version of the neighborhood assessment data, no neighborhood factor predicted dating violence. The implications and limitations of these findings are discussed.     

Alcohol Outlets,Neighborhood Characteristics,and Intimate Partner Violence: Ecological Analysis of a California City

Neighborhood indicators of social disadvantage, such as poverty and unemployment, are associated with intimate partner violence (IPV). Despite the well-established link between heavy drinking and IPV, few studies have analyzed the contribution of alcohol outlet density to the occurrence of IPV. Greater numbers of alcohol outlets in a community may be a sign of loosened normative constraints against violence, promote problem drinking among at-risk couples, and provide environments where groups of persons at risk for IPV may form and mutually reinforce IPV-related attitudes, norms, and problem behaviors. This study used ecological data to determine if alcohol outlet density (number of bars, restaurants serving alcohol, and off-premise outlets per unit area) is related to rates of IPV-related police calls and IPV-related crime reports in Sacramento, California. Separate analyses for IPV calls and crime reports were conducted using Bayesian space–time models adjusted for area characteristics (poverty rate, unemployment rate, racial/ethnic composition). The results showed that each additional off-premise alcohol outlet is associated with an approximate 4% increase in IPV-related police calls and an approximate 3% increase in IPV-related crime reports. Bars and restaurants were not associated with either outcome. The findings suggest that alcohol outlet density, especially off-premise outlets, appear to be related to IPV events. Further research is needed to understand the mechanisms by which neighborhood factors, such as alcohol outlet density, affect IPV behaviors. Understanding these mechanisms is of public health importance for developing environmental IPV prevention strategies, such as changes in zoning, community action, education, and enforcement activities.     

Multilevel spatiotemporal change-point models for evaluating the effect of an alcohol outlet control policy on changes in neighborhood assaultive violence rates

Many previous studies have suggested a link between alcohol outlets and assaultive violence rates. In 1997 the City of New Orleans adopted a series of policies, e.g., increased license fee, additional enforcement staff, and expanded powers for the alcohol license board. The policies were specifically enacted to address the proliferation of problem alcohol outlets believed to be the source of a variety of social problems including assaultive violence. In this research, we evaluate the impact of a city level policy in New Orleans to address the problem alcohol outlets and their influence on assaultive violence. The spatial association between rates of assaultive violence at the census tract level (n=170) over a ten year period raises a challenge in statistical analysis. To meet this challenge we developed a hierarchical change-point model that controls for important covariates of assaultive violence and accounts for unexplained spatial and temporal variability. While our model is somewhat complex, its hierarchical Bayesian analysis is accessible via the WinBUGS software program. Keeping other effects fixed, the implementation of the new city level policy was associated with a decrease in the positive association between census tract level rates of assaultive violence and alcohol outlet density. Comparing several candidate change-point models using the DIC criterion, the positive association began decreasing the year of the policy implementation. The magnitude of the association continued to decrease for roughly two years and then stabilized. We also created maps of the fitted assaultive violence rates in New Orleans, as well as spatial residual maps which, together with Moran's I's, suggest that the spatial variation of the data is well accounted for by our model. We reach the conclusion that the implementation of the policy is associated with a significant decrease in the positive relationship between assaultive violence and the off-sale alcohol outlet density.     

A Multilevel Analysis of Neighborhood Context and Youth Alcohol and Drug Problems

Various sources of data were used to examine hypothesized relations among neighborhood variables and youth alcohol and drug problems. Family members (N = 1186) were from 55 neighborhoods: 57% female, 41% African American, and 59% White. Data were clustered by neighborhood and analyzed within a multilevel design. At the neighborhood level, the study examined relations among poverty, stores selling alcohol, neighborhood social cohesion, neighborhood problems with youth alcohol and drug use, and drug and alcohol arrests. At the individual level, gender, ethnicity, adult versus child status, neighborhood social cohesion, and neighborhood problems were examined. Results indicated that more stores sold alcohol in higher poverty neighborhoods, which was associated with less social cohesion. Lower social cohesion was related to greater perceived neighborhood problems with youth alcohol and drug use, which was positively related to neighborhood youth drug and alcohol arrests. The study showed significant variation across neighborhoods and demonstrates the utility of combining different sources of neighborhood data to examine relations of interest.     

Neighborhood violent crime and unemployment increase the risk of coronary heart disease: a multilevel study in an urban setting

Little is known about the association between neighborhood social disorganization and coronary heart disease (CHD). This study used the theoretical frameworks of the Chicago school and the Stirling County group in order to analyze the impact of neighborhood violent crime and neighborhood unemployment on CHD in an urban setting, the capital of Sweden. The entire population of Stockholm County aged 35-64 years on January 1, 1998 was included in the study. All individuals were followed for CHD until December 31, 1998. Small area neighborhood units were used to define neighborhoods. The neighborhood-level variables were calculated as rates of violent crime or unemployment in the small area neighborhood units, categorized in quintiles. Multilevel logistic regression was used to estimate odds ratios and neighborhood-level variance in three different models. When rates of neighborhood violent crime or neighborhood unemployment increased, the risk of CHD increased among both women and men. In neighborhoods with the highest rates of violent crime (quintile 5), the odds ratios were 1.75 (CI=1.37-2.22) and 1.39 (CI=1.19-1.63) for women and men, respectively. In neighborhoods with the highest unemployment rates, the corresponding odds ratios were 2.05 (CI=1.62-2.59) and 1.50 (CI=1.28-1.75). These average neighborhood effects on CHD (fixed effects) remained almost unaltered after inclusion of the individual-level variables. The neighborhood-level variance indicated significant differences in CHD between neighborhoods, and the neighborhood-level and individual-level variables partly explained the variance between neighborhoods (random effects). Public safety and social stability in socially disorganized neighborhoods need to be improved in order to promote cardiovascular health.     

Association of neighborhood-level social determinants and food environments with pediatric hypertension care

Despite the apparent relationship between neighborhood characteristics and health, few studies of child health address neighborhood-level barriers, which may contribute to clinic no-show rates and difficulties following treatment plans in children and youth. We used longitudinal data from an outpatient hypertension clinic to examine neighborhood social disorganization, built environments, and their associations with patients’ clinic attendance and the risk of obesity/hypertension using mixed-effects regression models. Patients from disorganized neighborhoods were less likely to attend a baseline visit, and more likely to develop overweight/obesity and hypertension during follow-up. High-level fast-food expenditures in the neighborhood were associated with higher BMI percentiles and SBP during follow-up.     

Structural racism in the built environment: Segregation and the overconcentration of alcohol outlets

Structural racism, evidenced in practices like residential racial segregation, has been linked to health inequities. We examined the relationship between an adverse environmental factor (alcohol outlet overconcentration), segregated neighborhoods, and county alcohol policy in Louisiana and Alabama to investigate this link. Multilevel analysis revealed high outlet density associated with segregated counties and predominantly black census tracts in counties with restrictive alcohol policy. This inverse association between policies designed to limit alcohol availability and overconcentration of outlets in black neighborhoods warrants consideration by policymakers given links between outlet density and health inequities. Consideration of these findings in historical context suggests these policies may function as a contemporary actualization of the historical use of alcohol policy to subjugate black people in the South, now over-concentrating instead of prohibiting access.     

McDonald's restaurants and neighborhood deprivation in Scotland and England

BACKGROUND: Features of the local fast food environment have been hypothesized to contribute to the greater prevalence of obesity in deprived neighborhoods. However, few studies have investigated whether fast food outlets are more likely to be found in poorer areas, and those that have are local case studies. In this paper, using national-level data, we examine the association between neighborhood deprivation and the density of McDonald's restaurants in small census areas (neighborhoods) in Scotland and England. METHODS: Data on population, deprivation, and the location of McDonald's Restaurants were obtained for 38,987 small areas in Scotland and England (6505 "data zones" in Scotland, and 32,482 "super output areas" in England) in January 2005. Measures of McDonald's restaurants per 1000 people for each area were calculated, and areas were divided into quintiles of deprivation. Associations between neighborhood deprivation and outlet density were examined during February 2005, using one-way analysis of variance in Scotland, England, and both countries combined. RESULTS: Statistically significant positive associations were found between neighborhood deprivation and the mean number of McDonald's outlets per 1000 people for Scotland (p<0.001), England (p<0.001), and both countries combined (p<0.001). These associations were broadly linear with greater mean numbers of outlets per 1000 people occurring as deprivation levels increased. CONCLUSIONS: Observed associations between presence or absence of fast food outlets and neighborhood deprivation may provide support for environmental explanations for the higher prevalence of obesity in poor neighborhoods.     

Perceptions of Prominent Neighborhood Individuals Regarding Neighborhood Factors and Intimate Partner Violence

Research addressing the impact of neighborhood factors on intimate partner violence (IPV) often lacks discussion of how and why such factors impact IPV. In order to address this gap, 16 prominent neighborhood individuals (PNI) from 4 low-income urban neighborhoods were asked to share through in-depth interviews their insights and perceptions of IPV as an issue in their neighborhoods, and the relationship between social and structural neighborhood-level factors and IPV. PNIs most often associated IPV with only physical violence. Several did not feel IPV was a significant issue in their neighborhood, confirming a lack of awareness and underreporting of IPV. However, other PNIs were able to speak of the relationship between IPV and neighborhood factors, including lack of opportunities for employment, vacant housing, trash management, lack of community awareness, and social capacity to act to address IPV. Results provide unique insights regarding the mechanisms linking neighborhood factors to IPV outcomes. These results contribute to a deeper understanding of contextual influences upon IPV, the development of tailored quantitative research and to the design of local multi-level public health IPV intervention and prevention efforts.     

Differential Effects of Neighborhood Type on Adolescent Alcohol Use in New Zealand

Identifying neighborhood typologies associated with adolescent alcohol use can inform the development of harm reduction strategies. Utilizing data from a nationally representative youth survey (n?=?4267) in New Zealand, latent class analysis was used to categorize neighborhood types (defined by 10 demographic, social and environmental indicators) to investigate their association with alcohol consumption and related harm. Three neighborhood types were distinguished: (1) “high outlet density and economic deprivation” (30 % of all neighborhoods); (2) “high deprivation, social disorganization, and unsafe” (38 %); and (3) “higher income, safe, and socially organized” (32 %). Significant ethnic variation was evident between neighborhood types. There was an age–group interaction in the main effects with significant associations between neighborhood type and drinking measures and harm most apparent among younger adolescents (<16 years), as described next. Compared to students residing in “higher income, safe, and socially organized” neighborhoods, the frequency of binge drinking and high typical consumption was significantly higher in students residing in “high outlet density and economic deprivation” and “high deprivation, social disorganization, and unsafe”, with students residing in “high outlet density and economic deprivation” also experiencing higher levels of alcohol-related harm. The findings that neighborhoods characterized by high deprivation and alcohol outlet density and low social organization and perceptions of safety were associated with risky drinking patterns and harm, specifically among young adolescents, underscores the importance of adopting a developmental approach to the study of contextual effects on adolescents.     

Running to the Store? The relationship between neighborhood environments and the risk of obesity

We expand the search for modifiable features of neighborhood environments that alter obesity risk in two ways. First, we examine residents' access to neighborhood retail food options in combination with neighborhood features that facilitate physical activity. Second, we evaluate neighborhood features for both low income and non-low income neighborhoods (bottom quartile of median neighborhood income versus the top three quartiles).Our analyses use data from the Utah Population Database merged with U.S. Census data and Dun & Bradstreet business data for Salt Lake County, Utah. Linear regressions for BMI and logistic regressions for the likelihood of being obese are estimated using various measures of the individual's neighborhood food options and walkability features.As expected, walkability indicators of older neighborhoods and neighborhoods where a higher fraction of the population walks to work is related to a lower BMI/obesity risk, although the strength of the effects varies by neighborhood income. Surprisingly, the walkability indicator of neighborhoods with higher intersection density was linked to higher BMI/obesity risk. The expected inverse relationship between the walkability indicator of population density and BMI/obesity risk is found only in low income neighborhoods.We find a strong association between neighborhood retail food options and BMI/obesity risk with the magnitude of the effects again varying by neighborhood income. For individuals living in non-low income neighborhoods, having one or more convenience stores, full-service restaurants, or fast food restaurants is associated with reduced BMI/obesity risk, compared to having no neighborhood food outlets. The presence of at least one healthy grocery option in low income neighborhoods is also associated with a reduction in BMI/obesity risk relative to no food outlets. Finally, multiple food options within a neighborhood reduce BMI/obesity risk, relative to no food options, for individuals living in either low-income or non-low neighborhoods.     

Neighborhood support and the birth weight of urban infants

Differences in maternal characteristics only partially explain the lower birth weights of infants of African-American women. It is hypothesized that economic and social features of urban neighborhoods may further account for these differences. The authors conducted a household survey of 8,782 adults residing in 343 Chicago, Illinois, neighborhoods to assess mean levels of perceived social support and used US Census data to estimate neighborhood economic disadvantage. Data on birth weight and maternal risk factors were gathered from 95,711 birth certificates (1994-1996). Before statistical adjustment of the data, infants born to African-American mothers were found to be, on average, 297 g lighter than those born to White mothers. After adjustment for individual-level risk factors, this difference was reduced to 154 g. For African-American mothers only, mean birth weight decreased significantly as the neighborhood level of economic disadvantage increased. For White mothers only, a significant positive association was found between perceived levels of neighborhood social support and infant birth weight. Adding these neighborhood-level predictors to the model reduced the adjusted White versus African-American difference in birth weight to 124 g. Results support the hypothesis that neighborhood-level factors are significantly associated with infant birth weight.     

Evaluation of alcohol outlet density and its relation with violence

OBJECTIVES: The current study set out to investigate alcohol availability in a densely populated, residential area of suburban S?o Paulo associated with high levels of social deprivation and violence. Gun-related deaths and a heavy concentration of alcohol outlets are notable features of the area surveyed. Given the strong evidence for a link between alcohol availability and a number of alcohol-related problems, including violent crime, measures designed to reduce accessibility have become a favored choice for alcohol prevention programs in recent years. METHODS: The interviewers were 24 residents of the area who were trained for the study. It was selected an area of nineteen streets, covering a total distance of 3.7 km. A profile of each alcohol outlet available on the area was recorded. RESULTS: One hundred and seven alcohol outlets were recorded. The number of other properties in the same area was counted at 1,202. Two measures of outlet density may thus be calculated: the number of outlets per kilometer of roadway (29 outlets/km); and the proportion of all properties that sold alcohol (1 in 12). CONCLUSIONS: The results of this study is compared with others which are mainly from developed countries and shown that the area studied have the highest density of alcohol outlet density ever recorded in the medical literature. The implication of this data related to the violence of the region is discussed. By generating a profile of alcohol sales and selling points, it was hoped to gain a better understanding of alcohol access issues within the sample area. Future alcohol prevention policy would be well served by such knowledge.
