Once online poker, always online poker? Poker modality trajectories over two years.

Online poker is considered more at-risk than land-based poker in terms of intense gambling behaviors and gambling problems. The development of many online gambling sites has raised public health concerns about the potential increase in online poker players. Longitudinal studies are useful to better understand the evolution of gambling behaviors; however, very few consider online poker players.

Real-World Eligibility for HIV Pre-exposure Prophylaxis Among People Who Inject Drugs.

Recent studies have highlighted the efficacy of and willingness to use pre-exposure prophylaxis (PrEP) to prevent HIV infection among people who inject drugs (PWID), however knowledge of real-world applicability is limited. We aimed to quantify the real-world eligibility for HIV-PrEP among HIV-negative PWID in Montreal, Canada (n = 718). Eligibility was calculated according to US Centers for Disease Control and Prevention (CDC) guidelines and compared to risk of HIV acquisition according to the assessing the risk of contracting HIV (ARCH-IDU) risk screening tool.

Gambling Problem Trajectories and Associated Individuals Risk Factors: A Three-Year Follow-Up Study Among Poker Players.

Despite the popularity in poker-related activities in recent years, few studies have focused on the evolution of gambling habits of poker players over a long period of time. The aim of this study is to examine factors influencing trajectories of poker players. The results are based on data collected at a four-time measurement of a prospective cohort study conducted in Quebec (n = 304 poker players).

[Clinical profile of adolescents being treated for problematic internet use].

Objectives: This study highlights the clinical profile of adolescents having consulted with an addiction treatment center (ATC) in Québec for a problematic internet use (PIU) to develop knowledge about these specific clients and precisely target their needs relative to treatment.

Method: The study was conducted with 80 adolescents between ages 14 and 17 (M = 15.59) who had consulted with an ACT for a PIU.

Risk and protective factors for heat-related events among older adults of Southern Quebec (Canada): The NuAge study.

Objectives: Extreme heat is known to increase heat-related health outcomes (HRHO). Incidence and predictors of HRHO were examined among older adults living in Quebec (Canada).

Method: This prospective five-year study used data from the first follow-up of community-dwelling older adults from the NuAge cohort (2005-2006), located in three health regions of Southern Quebec.

Prevalence and correlates of prescription opioid residue injection.

Background: There is growing evidence of intravenous administration of prescription opioids (POs) in several countries. Preparation of POs for injection may leave residues in containers and filters used by people who inject drugs and may lead to adverse health outcomes if they are injected.

Methods: This exploratory study used cross-sectional data from the COSMO study, a prospective cohort of out-of-treatment cocaine users carried out in Montréal (Canada) between October 2010 and August 2015.

Predictors of residential stability among homeless young adults: a cohort study.

Background: Homelessness episodes have been shown to be associated with serious health outcomes among youth. This study was undertaken to estimate the probability of reaching residential stability over time and to identify predictors of residential stability among homeless young adults aged 18 to 25 years.

Methods: A prospective cohort study was carried out in Montréal, Canada, between April 5(th) 2006 and January 21(th) 2009.

Prevalence of risk and protective factors associated with heat-related outcomes in Southern Quebec: A secondary analysis of the NuAge study.

Objectives: Heat vulnerability is increasing owing to climate change, aging and urbanization. This vulnerability may vary geographically. Our study examined the prevalence and distribution of risk and protective factors of heat-related outcomes among older adults across three health regions of Southern Quebec (Canada).

Anxiety, mood disorders and injection risk behaviors among cocaine users: Results from the COSMO study.

Background And Objectives: Despite being common among cocaine users, mental health problems and their relationship with HIV and hepatitis C high risk injection behaviors are poorly documented. This study was undertaken to examine the relationships between mood and anxiety disorders and the sharing of drug injection equipment among cocaine users who inject drugs.

Methods: The sample was drawn from a prospective cohort study and comprised of 387 participants.

Surveillance of social and geographic inequalities in housing-related issues: the case of the Eastern Townships, Quebec (Canada).

Even though health inequalities are conditioned by many aspects of the environment, much of the existing research focuses on the social environment. This emphasis has the effect to neglect other environmental aspects such as its physical dimension. The physical environment, which is linked to housing conditions, may contribute to the uneven distribution of health.
