RESUMEN
PURPOSE: Child and adolescent obesity is increasingly prevalent and predisposes risk for poor physical and psychosocial health. Physical and social factors in the environment, such as neighborhood disorder, may be associated with childhood obesity. This study examines the association between living in a disordered neighborhood and being overweight among a sample of urban schoolchildren. DESIGN: Baseline interview data, including height, weight, and hip circumference, were obtained from 313 elementary school-aged participants in a community-based epidemiologic study. SETTING: The setting was Baltimore, Maryland, a large metropolitan city. SUBJECTS: Subjects were elementary school students ages 8 to 12 years. MEASURES: To assess neighborhood characteristics, independent evaluators conducted objective environmental assessments using the Neighborhood Inventory for Environmental Typology instrument on the block faces (defined as one side of a city block between two intersections) where the children resided. ANALYSIS: Logistic regression models with generalized estimating equations were used to examine the association between neighborhood disorder and children being overweight. RESULTS: Neighborhood disorder showed a trend toward a statistically significant association with being overweight during childhood (odds ratio [OR], 1.03; confidence interval [CI], .99-1.07; p = .07) in the unadjusted model. Gender was significantly associated with being overweight, with female gender increasing the odds of being overweight by 50% in the sample (OR, 1.50; CI, 1.18-1.92; p < .01). After controlling for race, age, and comparative time spent on a sport, multivariable analyses revealed that gender (adjusted odds ratio [AOR], 2.42; CI, 1.63-3.59; p < .01) and neighborhood disorder (AOR, 1.09; CI, 1.03-1.15; p < .01) were associated with being overweight. Further, an examination of interactions revealed girls (AOR, 2.40; CI, 1.65-3.49; p < .01) were more likely to be overweight compared with boys (AOR, 2.20; CI, 1.57-3.11; p < .01) living in neighborhoods with the same level of neighborhood disorder. CONCLUSION: Results suggest neighborhood hazards warrant additional consideration for their potential as obesogenic elements affecting gender-based disparities in weight among urban schoolchildren. Future studies in this area should include longitudinal examinations.

Motivational theorists in psychology have moved away from individual-based approaches to socio-cognitive and socio-ecological models to explain student engagement and motivation for learning. Such approaches consider, for example, the influence of family and neighborhood environments as important constructs in youth behavior. In this study, links between neighborhood condition (e.g. external appearance of the blocks nearest to the respondents' home), family dysfunction, and motivation for learning are investigated. Data were obtained from two hundred and sixteen (216) urban African American middle school children enrolled in a substance use prevention intervention. Analytic models show associations between poor neighborhood condition and both family dysfunction and lower learning motivation. Family dysfunction was also found to mediate the effect of neighborhood condition on motivated learning. Neighborhood and family characteristics are important determinants of urban schoolchildren's motivation for learning.
RESUMEN
This research examines the relationship between neighborhood physical and social disorder and incarceration history among urban drug users. A cohort of 358 African American and White urban drug users completed a clinical interview and psychological assessment that emphasized cognitive and social-behavioral HIV risk factors. The Neighborhood Inventory for Environmental Typology was used to assess indicators of physical and social disorder. After controlling for age, gender, education, and having a place to live, multivariable analyses revealed that living in a neighborhood with moderate or high levels of disorder (odds ratio [OR] = 1.63; 95% confidence interval [CI] = [1.02, 2.59]) and drinking alcohol every day or nearly every day for 3 months or more (OR = 2.03; 95% CI [1.24, 3.31]) were associated with incarceration history. Findings suggest that select characteristics of disadvantaged communities may be important determinants of incarceration vulnerability among urban substance users. Residential improvements hold promise to enhance interventions aimed to reduce incarceration.

This report examines associations between hepatitis A virus (HAV) infection prevalence and a history of incarceration in jail or a correctional facility among a population of drug users in Baltimore stratified by African American and white racial/ethnic status. The study sample consisted of 509 non-injection and injection drug users recruited from inner-city neighborhoods of the Baltimore metropolitan region. The baseline prevalence of HAV infection was 36.9% (N=188). One-fourth (25.5%) of the sample reported no lifetime history of incarceration, 44.6% reported incarceration in a local jail in their lifetime, and 29.9% reported incarceration in a correctional facility in their lifetime. In the multivariate logistic analysis, HAV infection prevalence was higher for whites (44.3%) [adjusted odds ratio (AOR)=2.3, 95% CI=1.5-3.5] when compared to African Americans (30.5%) adjusting for gender, age, and education. In the analysis stratified by race/ethnicity, as anticipated, jail incarceration and correctional facility incarceration were each independently associated with elevated HAV prevalence among white drug users. African American drug users with a high school diploma had significantly lower HAV infection prevalence when compared to African American drug users who did not graduate from high school. Heightened HAV prevalence among white drug users compared to African American drug users is noteworthy given the opposite association of HAV infection prevalence and these two racial/ethnic groups in the general population. Since millions of incarcerated drug users in the US return to society each year, the results suggest that incorporating systematic HAV screening, prevention, and treatment programs within correctional systems represents a vital yet underutilized strategy to reduce HAV transmission in society as a whole.

Individuals with severe and persistent mental illness (SPMI) have a preponderance of weight problems, possibly even greater than the obesity epidemic in the general population. Although atypical antipsychotics cause weight gain, their contribution to obesity has not been characterized in a community setting where individuals may take multiple psychotropics associated with weight gain. Using survey information including measured height and weight from a random sample of Maryland Medicaid recipients with SPMI, we compared obesity prevalence to the National Health and Nutrition Examination Survey (NHANES III) sample and a Maryland sample (Behavioral Risk Factor Surveillance System) of the general population adjusted to SPMI demographic characteristics. We investigated correlates of obesity in the SPMI sample. The results indicate that both men and especially women with SPMI had a higher prevalence of obesity than the general population; this portends substantial health implications. A fourfold association between atypical antipsychotics and prevalent obesity was found in men but not in women; further work should clarify mechanisms of obesity in the SPMI.
