While the community impacts of drug-related street disorder have been well described, lesser attention has been given to the potential health and social implications of drug scene exposure on street-involved people who use illicit drugs. Therefore, we sought to assess the impacts of exposure to a street-based drug scene among injection drug users (IDU) in a Canadian setting. Data were derived from a prospective cohort study known as the Vancouver Injection Drug Users Study. ⋯ Our findings indicate that drug scene exposure is associated with markers of vulnerability and higher intensity addiction. Intensity of drug scene exposure was associated with indicators of vulnerability to harm in a dose-dependent fashion. These findings highlight opportunities for policy interventions to address exposure to street disorder in the areas of employment, housing, and addiction treatment.

The negative impact of extreme temperatures on health is well-established. Individual help-seeking behavior, however, may mitigate the extent of morbidity and mortality during elevated temperatures. This study examines individual help-seeking behavior during periods of elevated temperatures among a Chinese population. ⋯ Call frequency among females appeared to be more sensitive to high temperatures, with a threshold between 28.5°C and 30.5°C while calls among males were more sensitive to cold temperatures (threshold 31.5-33.5°C). Results indicate differences in community help-seeking behavior at elevated temperatures. Potential programs or community outreach services might be developed to protect vulnerable subgroups from the adverse impact of elevated temperatures.

Adolescent obesity is a national public health problem, particularly among urban populations. Recent evidence has linked neighborhood food environments to health and nutrition status, with easier access to convenience stores being associated with increased risk for obesity. Little is known about the availability of healthy purchasing options within small, urban food stores, or the extent to which these factors are relevant to youth. ⋯ All stores had less healthful impulse purchase items available (e.g., candy) while only 46% carried healthier impulse items (e.g., fruit). Most stores (97%) had food/beverage advertising. Overall, convenience stores located in close proximity to secondary schools represent an important and understudied component of the youth food environment.

Evidence has linked residential instability and engagement in high-risk behaviors. This paper longitudinally examines the relationship between changes in residential stability and changes in HIV risk behaviors among Montréal street youth (SY). Between April 2006 and May 2007, 419 SY (18-25 years old) were recruited in a cohort study. ⋯ Residential stability was significantly associated with the following: sex exchange (adjusted odd ratio [AOR], 0.25; 95% confidence interval [CI], 0.14-0.37), drug injection (AOR, 0.55; CI, 0.33-0.76), daily alcohol consumption (AOR, 0.58; CI, 0.42-0.74), polydrug consumption (AOR, 0.61; CI, 0.50-0.73), polydrug consumption excluding marijuana (AOR, 0.55; CI, 0.45-0.65), and multiple sex partners (≥3 partners; AOR, 0.57; CI, 0.40-0.74). Our results suggest a reciprocal relationship between residential instability and HIV risk behaviors. This calls for more integrated services combining both individual and structural-level interventions to improve the health of street youth.

Injection drug users (IDUs) are at risk for acquiring human immunodeficiency virus (HIV) through parenteral and sexual transmission. In this paper, we describe the prevalence and correlates of unsafe drug injecting and sexual behaviors among IDUs recruited across five cities in Georgia in 2009. IDUs were administered a questionnaire collecting information on demographics, drug use, sexual behaviors, and HIV testing behaviors. ⋯ The following variables were significantly associated with unsafe injecting behavior at last injection and not using condoms at last sex with commercial and/or occasional partners in the multivariate analysis: marital status [p = 0.0002; (for divorced, widowed, and separated aOR = 2.62, 1.62-4.25; for single aOR = 1.61, 1.08-2.39)], being a member of a regular injecting group (aOR = 0.62, 0.44-0.88), types of drugs injected in the past month [p = 0.0024; (for buprenorphine aOR = 0.34, 0.18-0.63)], city of residence (p = 0.0083), and not receiving information on HIV (aOR = 1.82, 1.07-3.09). Though only ephedrine was injected by a smaller number of IDUs (9.1%), the vast majority of these (81.4%) reported unsafe injecting practices at last injection. High prevalence of unsafe injecting behaviors and diverse and at-risk sexual partnerships highlight the need to implement complex and targeted HIV interventions among IDUs in Georgia.
