Abstract
PURPOSE To compare the role of neighborhood social disorganization factors on human immunodeficiency virus (HIV) diagnosis rates in urban and rural areas in Florida, we conducted an ecologic study of HIV diagnosis rates during 2013-2017 and social disorganization components, including concentrated disadvantage, ethnic heterogeneity, and residential instability. METHODS Indices of social disorganization components were obtained from principal component analyses of American Community Survey variables for 910 postal codes. Rural/urban classification was based on the United States Department of Agriculture Rural Urban Commuting Area codes. Using multivariable linear regression, the relationship between social disorganization indices and HIV diagnosis rates was assessed. FINDINGS The only social disorganization index that was significantly higher in rural than urban areas was concentrated disadvantage. In rural areas, the concentrated disadvantage index was significantly associated with HIV diagnosis rates (P = .007) when controlling for the other social disorganization factors but was no longer significant after additionally controlling for prevalence of people with an HIV diagnosis who were not virally suppressed. In urban areas, even after controlling for prevalence of people with HIV who were not virally suppressed, lower male-to-female population ratios and higher scores of residential instability, concentrated disadvantage, and LatinX/immigrant density indices were associated with higher HIV diagnosis rates (all P < .01). CONCLUSIONS In addition to improving community levels of viral suppression, the community contextual environment, including the rurality of the environment, needs to be considered in strategies to end the HIV epidemic in the United States.

Abstract
Policing efforts to thwart crime typically rely on criminal infraction reports, which implicitly manifest a complex relationship between crime, policing and society. As a result, crime prediction and predictive policing have stirred controversy, with the latest artificial intelligence-based algorithms producing limited insight into the social system of crime. Here we show that, while predictive models may enhance state power through criminal surveillance, they also enable surveillance of the state by tracing systemic biases in crime enforcement. We introduce a stochastic inference algorithm that forecasts crime by learning spatio-temporal dependencies from event reports, with a mean area under the receiver operating characteristic curve of ~90% in Chicago for crimes predicted per week within ~1,000 ft. Such predictions enable us to study perturbations of crime patterns that suggest that the response to increased crime is biased by neighbourhood socio-economic status, draining policy resources from socio-economically disadvantaged areas, as demonstrated in eight major US cities.

Abstract
Sexually transmitted infections (STIs) remain serious public health problems particularly in urban environments in the USA. Despite accumulating research into the role of aggregate rates of crime in shaping rates of STIs, few studies account for spatial dependence in the structure of geographical data. Using multiple spatial analysis methodologies, the following study investigated spatial patterns in community area rates of violent, drug, and property crimes and rates of infection of gonorrhea and chlamydia in 77 community areas in Chicago. Moran's I analyses confirmed global spatial dependence and statistically significant clusters of STI. Spatial lag regression analyses found that greater rates of drug crimes were associated with higher rates of chlamydia and gonorrhea after adjusting for percent in poverty and racial composition. Finally, a weighted geographic regression identified regions in the urban environment in which local regression coefficient values diverged from their global estimates. Spatial heterogeneity of STIs suggest that public health interventions must be targeted to specific areas of the urban environment with particular attention to substance use.

Abstract
Identifying predictors that contribute to geographic disparities in sexually transmitted infections (STIs) is necessary in order to reduce disparities. This study assesses the spatial relationship condom availability and accessibility in order to better identify determinants of geographic disparities in STIs. We conducted a telephone-based audit among potential-condom selling establishments. Descriptive analyses were conducted to detect differences in condom-selling characteristics by stores and by store type. Geocoding, mapping, and spatial analysis were conducted to measure the availability of condoms. A total of 850 potential condom-selling establishments participated in the condom availability and accessibility audit in St. Louis city; 29 % sold condoms. There were several significant geographic clusters of stores identified across the study area. The first consisted of fewer convenience stores and gas stations that sold condoms in the northern section of the city, whereas condoms were less likely to be sold in non-convenience store settings in the southwestern and central parts of the city. Additionally, locations that distributed free condoms clustered significantly in city center. However, there was a dearth of businesses that were neither convenience stores nor gas stations in the northern region of the city, which also had the highest concentration of condoms sold. This initial study was conducted to provide evidence that condom availability and accessibility differ by geographic region, and likely are a determinant of social norms surrounding condom use and ultimately impact STI rates.

Abstract
INTRODUCTION The adverse health effects of lead exposure in children are well documented and include intellectual and behavioral maladies. Childhood lead exposure has also been linked to impulsive behaviors, which, in turn, are associated with a host of negative health outcomes including an increased risk for sexually transmitted infections (STI). The purpose of this study was to assess the association of lead exposure with STI rates across census tracts in St. Louis City, Missouri. METHODS Incident cases of gonorrhea and chlamydia (GC) during 2011 were identified from the Missouri Department of Health and Senior Services and aggregated by census tract. We also geocoded the home address of 59,645 children >72 months in age who had blood lead level tests performed in St. Louis City from 1996 to 2007. Traditional regression and Bayesian spatial models were used to determine the relationship between GC and lead exposure while accounting for confounders (condom and alcohol availability, crime, and an index of concentrated disadvantage). RESULTS Incident GC rates were found to cluster across census tracts (Moran's I=0.13, p=0.006). After accounting for confounders and their spatial dependence, a linear relationship existed between lead exposure and GC incidence across census tracts, with higher GC rates occurring in the northern part of St. Louis City CONCLUSIONS At the census-tract level, higher lead exposure is associated with higher STI rates. Visualizing these patterns through maps may help deliver targeted interventions to reduce geographic disparities in GC rates.

Abstract
Ecologic and cross-sectional multilevel analyses suggest that characteristics of the places where people live influence their vulnerability to HIV and other sexually-transmitted infections (STIs). Using data from a predominately substance-misusing cohort of African-American adults relocating from US public housing complexes, this multilevel longitudinal study tested the hypothesis that participants who experienced greater post-relocation improvements in economic disadvantage, violent crime, and male:female sex ratios would experience greater reductions in perceived partner risk and in the odds of having a partner who had another partner (i.e., indirect concurrency). Baseline data were collected from 172 public housing residents before relocations occurred; three waves of post-relocation data were collected every 9 months. Participants who experienced greater improvements in community violence and in economic conditions experienced greater reductions in partner risk. Reduced community violence was associated with reduced indirect concurrency. Structural interventions that decrease exposure to violence and economic disadvantage may reduce vulnerability to HIV/STIs.

Abstract
BACKGROUND Cross-sectional and ecologic studies suggest that place characteristics influence sexual behaviors and sexually transmitted infections (STIs). Using data from a predominately substance-misusing cohort of African American adults relocating from US public housing complexes, this multilevel longitudinal study tested the hypothesis that participants who experienced greater postrelocation improvements in neighborhood conditions (i.e., socioeconomic disadvantage, social disorder, STI prevalence, and male/female sex ratios) would have reduced the odds of testing positive for an STI over time. METHODS Baseline data were collected in 2009 from 172 public housing residents before relocations occurred; 3 waves of postrelocation data were collected every 9 months thereafter. Polymerase chain reaction methods were used to test participants' urine for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Individual-level characteristics were assessed via survey. Administrative data described the census tracts where participants lived at each wave (e.g., sex ratios, violent crime rates, and poverty rates). Hypotheses were tested using multilevel models. RESULTS Participants experienced improvements in all tract-level conditions studied and reductions in STIs over time (baseline: 29% tested STI positive; wave 4: 16% tested positive). Analyses identified a borderline statistically significant relationship between moving to tracts with more equitable sex ratios and reduced odds of testing positive for an STI (odds ratio, 0.16; 95% confidence interval, 0.02-1.01). Changes in other neighborhood conditions were not associated with this outcome. DISCUSSION Consonant with past research, our findings suggest that moving to areas with more equitable sex ratios reduces the risk of STI infection. Future research should study the extent to which this relationship is mediated by changes in sexual network dynamics.

Abstract
Adolescents and young adults have the highest rates of sexually transmitted infections (STIs) in the USA despite national priority goals targeting their reduction. Research on the role of neighborhoods in shaping STI risk among youth has increased in recent years, but few studies have explored the longitudinal effects of neighborhoods on STI acquisition during the adolescent to young adult transition. The aims of this study were to examine: (1) the longitudinal relationships between the neighborhood context (poverty, residential instability, and racial/ethnic concentration) of exposure during adolescence and young adults' acquisition of chlamydia, and (2) the extent to which sexual risk behaviors and depression over the transition from adolescence to young adulthood mediate the relationship between the neighborhood context of exposure during adolescence and young adults' acquisition of chlamydia. A longitudinal observational design was employed using data from the National Longitudinal Study of Adolescent Health (Add Health), waves 1-3 (1994-2002). The sample was composed of 11,460 young adults aged 18 to 27 years. Neighborhood measures during adolescence were derived from the 1990 US Census appended to adolescents' interview data. Chlamydia infection was measured via urine assay at wave 3 and 4.6 % of the young adults in the sample tested positive for chlamydia. Multilevel logistic regression analyses were conducted adjusting for numerous neighborhood and individual risk factors. Multivariate findings indicated exposure to neighborhood poverty during adolescence increased the likelihood of a positive urine test for chlamydia during young adulthood (AOR = 1.23, 95 % CI = 1.06, 1.42), and the association was not mediated by sexual risk behaviors or depression. Further research is needed to better understand the pathways through which exposure to neighborhood poverty contributes to chlamydia over the life course as are comprehensive STI prevention strategies addressing neighborhood poverty.

Abstract
BACKGROUND The residential segregation of black populations, often in areas of high-economic disadvantage and low social status, may play a crucial role in the observed racial inequities in sexually transmitted disease rates. METHODS An ecological analysis of 2005 to 2009 average gonorrhea rates was performed across 277 US metropolitan statistical areas (MSAs). The black isolation index and Gini index of income inequality were used as proxy measures for racial and economic residential segregation respectively, derived from 2005 to 2009 US Census estimates. We used logistic regression modeling to produce estimates of odds ratios (ORs) and 95% confidence intervals (CIs) for the association between the segregation indices, both independently and in combination, on gonorrhea rates in MSAs. Effect measure modification was assessed by calculating the relative excess risk due to interaction between the 2 indices. RESULTS Compared with MSAs with low levels of racial segregation, MSAs with high levels of racial segregation had increased odds of high gonorrhea rates (adjusted OR, 3.37; 95% CI, 1.23-9.21). Similarly, higher levels of income inequality predicted higher gonorrhea rates, although this association did not persist after adjustment for potential confounders (adjusted OR, 1.54; 95% CI, 0.74-3.24). In combined models, the influence of racial residential segregation on gonorrhea rates was stronger than that of income inequality-based segregation; there was no evidence of additivity or a multiplicative interaction. CONCLUSIONS Residential segregation by race or income equality may be a key component in the perpetuation of high rates of gonorrhea and other sexually transmitted diseases among black populations in the United States.

Abstract
Data obtained from genitourinary medicine clinics through a comprehensive surveillance system were used in a Bayesian mixed-effects Poisson regression model to explore socio-demographic individual and ecological risk factors for gonorrhoea in London, as well as its spatial clustering. The spatial analysis was performed at the Middle-layer Super Output Area level (median population size 7200). A total of 12452 individuals were diagnosed during the 2-year study period (2009-2010). The study confirmed the presence of 'core areas' of high incidence, and identified 'core' high-risk groups, in particular young adults (16-29 years), males, black Caribbeans and more deprived areas. The individual (age, sex, ethnicity) and area-level (deprivation, teenage pregnancies, students) model covariates accounted for 48% of the variance. Most of the remaining variance was explained by the spatial effect, thus capturing other spatially distributed factors associated with gonorrhoea, such as local sexual networks. These findings will be useful in identifying areas for targeted interventions, such as STI testing and health promotion.

Abstract
OBJECTIVES In the United States, Black persons are disproportionately affected by sexually transmitted infections (STIs), including gonorrhea. Individual behaviors do not fully explain these racial disparities. We explored the association of racial residential segregation with gonorrhea rates among Black persons and hypothesized that specific dimensions of segregation would be associated with gonorrhea rates. METHODS We used 2003 to 2007 national STI surveillance data and 2000 US Census Bureau data to examine associations of 5 dimensions of racial residential segregation and a composite measure of hypersegregation with gonorrhea rates among Black persons in 257 metropolitan statistical areas, overall and by sex and age. We calculated adjusted rate ratios with generalized estimating equations. RESULTS Isolation and unevenness were significantly associated with gonorrhea rates. Centralization was marginally associated with gonorrhea. Isolation was more strongly associated with gonorrhea among the younger age groups. Concentration, clustering, and hypersegregation were not associated with gonorrhea. CONCLUSIONS Certain dimensions of segregation are important in understanding STI risk among US Black persons. Interventions to reduce sexual risk may need to account for racial residential segregation to maximize effectiveness and reduce existent racial disparities.

Abstract
OBJECTIVES We examined relationships between neighborhood social disorganization and trichomoniasis among young US adults. METHODS We employed multilevel logistic regression modeling with secondary data from wave III of the National Longitudinal Study of Adolescent Health (2001-2002). The dependent variable-trichomoniasis-was measured via urine testing. The measures for neighborhood social disorganization were derived from the 2000 US Census-racial and ethnic composition, concentrated poverty, and residential instability. The sample comprised 11 370 individuals across 4912 neighborhoods. RESULTS Trichomoniasis was more likely in neighborhoods with higher concentrations of Black residents (adjusted odds ratio [AOR] = 1.16; 95% confidence interval [CI] = 1.03, 1.30). However, this association was mediated by neighborhood concentrated poverty. Furthermore, young adults who lived in neighborhoods with higher concentrations of poverty were significantly more likely to have trichomoniasis (AOR = 1.25; 95% CI = 1.07, 1.46). Neither immigrant concentration nor residential instability was significantly associated with trichomoniasis. CONCLUSIONS These findings strengthen the evidence that neighborhood structural conditions are associated with individual sexually transmitted infection (STI) acquisition. Research is needed to explore the mechanisms through which these conditions influence STI. In addition, STI-prevention programs that include structural interventions targeting neighborhood disadvantage are needed.

Abstract
BACKGROUND This study examined racial differences in the prevalence of sexual risk behaviors and their associations with sexually transmitted diseases (STDs) among recent heroin-using and cocaine-using women. METHODS Participants were 214 women (59% black, 41% white) who were recruited during 2002-2010 using targeted sampling to participate in a study in Baltimore, Maryland, and reported using heroin, cocaine, or crack during the previous 6 months. Participants completed self-report questionnaires about their drug use, sexual risk behaviors, and lifetime history of one of six STDs, including gonorrhea, syphilis, chlamydia, genital herpes, genital warts, or trichomoniasis. RESULTS More black women (50%) than white women (28%) reported a lifetime STD. Although there were no racial differences in the lifetime prevalence of sexual risk behaviors assessed, there were racial differences in the sexual behaviors associated with ever having a lifetime STD. Simple logistic regressions revealed that ever having a casual sex partner or anal sex were correlates of having a lifetime STD among black women but not among white women. Multiple logistic regression analyses revealed that ever having a casual sex partner was significantly associated with having a lifetime STD among black women, and ever trading sex for money was significantly associated with having a lifetime STD among white women. CONCLUSIONS Findings are consistent with national studies and elucidate racial disparities in STDs and associated sexual behaviors among recent heroin-using and cocaine-using women. Findings underscore the need to tailor STD prevention interventions differently for black and white recent heroin-using and cocaine-using women.

Abstract
We assess whether there is evidence of an association between socioeconomic position (SEP) and HIV risk-relevant behavior among lower income heterosexual men and women in San Francisco. Respondents residing in low income areas with high heterosexual AIDS case burden in San Francisco were recruited through long-chain referral in 2006–2007. Risk measures included unprotected vaginal intercourse, concurrency and exchange sex. SEP was defined as household annual income, per capita income, and employment. Analyses utilized mixed and fixed effects models. A total of 164 men and 286 women were included in the study. SEP was only significant in the case of exchange sex among men: men reporting annual income greater than $30,000 had significantly lower odds of exchange sex relative to other men. Evaluating the connection between economic status and HIV requires additional studies covering diverse populations. Future studies should focus on community economic context as well as individual SEP.

Abstract
Our goal was to define the risk factors for Chlamydia trachomatis (CT) infection among pregnant women at a large urban medical centre. In a retrospective study, clinical records at a US maternity unit from July 2005 through February 2008 were reviewed. The study population included all pregnant women with a singleton newborn of at least 20 weeks gestation and antenatal care information. Logistic regression was used to analyse the association between a positive CT test and demographic, behavioural and prenatal care variables. A total of 2127 women were included in this analysis. The prevalence of CT infection was 4.7%. Cases were more likely to be younger, black and single. Other risk factors included tobacco use and Neisseria gonorrhoeae infection. Our findings suggest that factors other than age may impact upon the diagnosis of CT in pregnant women and that a more comprehensive testing strategy should be considered.
