Criminals illegally obtaining firearms represent a great risk to many urban residents. This cross-sectional study of 54 US cities uses data on state laws governing gun sales, a survey of law enforcement agencies' practices to promote compliance with gun sales laws, and crime gun trace data to examine associations between these policies and practices with gun trafficking indicators. Higher levels of local gun ownership were linked with greater intrastate gun trafficking. ⋯ The effects of these relatively restrictive gun purchase laws on trafficking may be mediated by the laws' lowering of gun ownership. Relatively low prevalence of gun ownership may also be a prerequisite for passage of discretionary purchase. We observed no effect on intrastate trafficking of laws limiting handgun sales to a maximum of one per person per month.

Gaps in understanding of how area-based differences in exposure to violence are associated with asthma prevalence may limit the development of effective prevention programs and the identification of risk for asthma episodes. The current investigation examines the associations between sexual violence victimization and asthma episodes among US adult women across three different metropolitan settings. The association between sexual assault victimizations and asthma attacks in the past year was examined using data from the 2005, 2006, and 2007 Behavioral Risk Factor Surveillance System surveys. ⋯ Our findings show that unwanted touching, attempted unwanted intercourse, forced unwanted intercourse, and any sexual violence victimization (touching, attempted intercourse, or forced intercourse) were significantly associated with asthma episodes (OR(adj.) = 3.67, 95% CI, 1.76-7.69; OR(adj.) = 1.77, 95% CI, 1.32-2.37; OR(adj.) = 2.24, 95% CI, 1.64-3.05, and OR(adj.) = 1.93, 95% CI, 1.47-2.53, respectively). While no significant differences in the associations between asthma episodes and metropolitan status were found, a significant interaction between non-metropolitan areas and attempted sexual intercourse was identified (OR(adj) = 0.53, 95% CI, 0.29-0.96). Sexual victimization appears to be an important, but understudied, correlate of asthma morbidity among adult women in the USA, suggesting that additional research is needed to better understand the associations between sexual violence, psychological distress, and asthma.

Studies have found that between 14% and 46% of US men who have sex with men (MSM) consistently report "barebacking" behavior (i.e., intentional unprotected anal intercourse) with other men. This is of public health significance because MSM continue to constitute more than 50% of new HIV infections in the USA. Men who self-identify as barebackers may represent a different and unique subset of MSM with distinct HIV prevention needs. ⋯ These findings suggest that barebacker identity is related to intentional HIV sexual risk taking and alcohol abuse. Furthermore, strategic positioning (i.e., engaging in insertive rather than receptive sex) might be associated with barebacker identification and may indicate a harm-reduction strategy being used among some HIV-uninfected MSM to reduce their risk of becoming infected. Additional research is warranted to understand the social identity of barebacking among MSM in order to develop more nuanced prevention strategies.

Central cities have lower childhood immunization coverage rates than states in which they are located. We conducted a secondary analysis of the National Immunization Survey (NIS) 2000 and 2006 of children 19-35 months old for 26 NIS-defined central cities and the rest of their respective states in order to examine patterns in early childhood immunization disparities between central cities and their respective states and the contextual factors associated with these disparities. We examined three measures of immunization disparities (absolute, difference, and ratio of change) and the patterns of disparity change with regard to selected contextual factors derived from the census. ⋯ Central cities with a larger share of Hispanics experienced less reduction in disparities than other cities (beta = -4.2, t = -2.11, p = 0.047). Despite overall progress in childhood immunization coverage, most central cities still show significant disparities with respect to the rest of their states. Cities with larger Hispanic populations may need extra help in narrowing their disparities.

Providing care for children with asthma can be demanding and time-intensive with far-reaching effects on caregivers' lives. Studies have documented childhood asthma symptom reductions and improved asthma-related quality of life (AQOL) with indoor allergen-reducing environmental interventions. Few such studies, however, have considered ancillary benefits to caregivers or other family members. ⋯ Time trends in caregiver AQOL, controlling for child AQOL, were not explained by available social support or caregiver stress measures. Our findings suggest potential participation effects not adequately captured by standard measures. Future environmental intervention studies should more formally consider social support and participation effects for both children and caregivers.
