AbstractBackgroundAimsMethodsResultsConclusionsLimited evidence exists regarding how sex differences in mental health are changing over time, especially in the context of recent health and economic adversities.To examine the temporal shifts in mental health issues among males and females, and explore the influence of education and loneliness on these trends.Data were utilized from the 2020 to 2023 Monitor study, a repeated cross-sectional survey of adults 18 years and older in Ontario, Canada. The study employed a Qualtrics-based web panel survey (n = 5,317). Mental health was assessed using Kessler-6 questionnaire, and analyses were performed using Generalized Linear Model (GLM) with gamma distribution.The results showed that there was a significant three-way interaction effect between sex, time and education with psychological distress (p = 0.014), suggesting that psychological distress increased between 2020 and 2023 among males who had less than college education. However, it remained stable among males with college/university degrees and females overall. Interaction between sex and feeling lonely on psychological distress was also evident (p = 0.004).Mental health issues remained a significant public health challenge among adults, especially psychological distress increasing among males with less than a college education. This underscores the importance of targeted interventions addressing males’ mental health. [ABSTRACT FROM AUTHOR]

Objectives: Drowsiness has been shown to impair reaction times, decision-making abilities, and awareness of hazards critical to driving in a manner similar to the effects of driving under the influence of alcohol.1 Drowsy driving has been estimated to cause thousands of fatal crashes per year and has resulted in billions of dollars in lost revenue.2 However, while breathalyzers and ignition interlock devices can be used to mitigate the risk of drunk driving, no such devices are commercially available for roadside or behind-the-wheel diagnostics for drowsiness. To address this gap, the objective of this study was to demonstrate the efficacy and feasibility of a breath sensor to detect fatigue and drowsiness in a simulated driving environment. Data and methods: Solid state breath sensors calibrated to previously identified breath biomarkers of fatigue and drowsiness were arrayed to determine changes in the breath profiles of subjects undergoing a full-motion driving simulation designed to elicit driver fatigue. A multi-sensor approach was used rather than relying on a single biomarker. The biomarker profile targeted compounds such as benzene derivatives (e.g., benzene, benzaldehyde, toluene, phenol), 2-butanone, and 2-ethyl-1-hexanol, among others. To address potential confounders such as eating/drinking, cigarette smoke, alcohol, and medical conditions like COPD or diabetes, the study was conducted under controlled conditions: participants refrained from eating for a couple of hours before the experiment, were nonsmokers, had not consumed alcohol for the past day, and had no known medical conditions. The breath biomarker profiles were then correlated with established drowsiness metrics, specifically the PERCLOS (Percentage of Eye Closure) and the Karolinska Sleepiness Scale (KSS). Results: The breath sensor array collected breath biomarker profiles for 61 subjects. The biomarker profiles demonstrated a trend consistent with increasing PERCLOS and KSS responses (see Figure). During the 60-minute driving simulation designed to elicit driver fatigue, the PERCLOS showed a steady increase in response over time, while the KSS did not show an increase in perceived sleepiness until the 60 min mark. Similarly, the breath biomarker sensor response showed a significant increase at the 60-minute timepoint, consistent with increases in both the PERCLOS and the KSS, demonstrating evidence of increased driver fatigue and drowsiness. Conclusions: These findings suggest that integrating drowsiness breath sensor arrays into vehicle systems could significantly enhance drowsiness detection, thereby reducing crashes, injuries, and fatalities. Moreover, the scalability and non-invasiveness of the proposed system lays the groundwork for broader applications, extending beyond vehicles to fields such as aviation and healthcare.

Background: Intimate partner violence (IPV) is a global public health crisis. Often repetitive and occurring over prolonged periods of time, IPV puts survivors at high risk of brain injury (BI). Mental health concerns are highly prevalent both among individuals who have experienced IPV and those who have experienced BI, yet the interrelatedness and complexity of these three challenges when experienced together is poorly understood. This qualitative study explored care provision for IPV survivors with BI (IPV-BI) and mental health concerns from the perspectives of both survivors and providers. Methods: This qualitative interpretive description study was part of a broader research project exploring employment, mental health, and COVID-19 implications for survivors of IPV-BI. Participants (N = 24), including survivors and service providers, participated in semi-structured group and individual interviews between October 2020 and February 2021. Interviews were recorded, transcribed, and thematically analyzed. Findings: Four themes were developed from interview findings: 1) identifying BI and mental health as contributing components to survivors' experiences is critical to getting appropriate care; 2) supporting survivors involves a "toolbox full of strategies" and a flexible approach; 3) connecting and collaborating across sectors is key; and 4) underfunding and systemic barriers hinder access to care. Finally, we share recommendations from participants to better support IPV survivors. Conclusions: Identifying both BI and mental health concerns among IPV survivors is critical to providing appropriate supports. Survivors of IPV experiencing BI and mental health concerns benefit from a flexible and collaborative approach to care; health and social care systems should be set up to support these collaborative approaches.

BACKGROUND: Mild traumatic brain injury (mTBI) can profoundly impact overall health, employment, and family life. Incidence of mTBI in the workplace represents an important subgroup with poorer outcomes. Mental health (MH) and substance use (SU) challenges are a primary correlate of TBI, but are rarely assessed among individuals with a work-related (wr)-mTBI, particularly at a population-level. OBJECTIVE: This study aimed to assess the association between lifetime wr-mTBI and non-wr-mTBI and the experience of MH and SU challenges. METHODS: The 2019 Centre for Addiction and Mental Health (CAMH) Monitor is a cross-sectional telephone survey of adults aged≥18 years in Ontario, Canada, employing a stratified (six regions) two-stage (telephone number, respondent) list-assisted random digit dialing probability selection procedure (N = 1792). Adjusting for sociodemographic variables, binary logistic regression was conducted to assess the association between lifetime wr-mTBI and non-wr-mTBI (relative to no TBI) and four outcomes: hazardous use of alcohol and of cannabis, psychological distress, and fair/poor mental health. RESULTS: Adjusting for sociodemographic variables, non-wr-mTBI demonstrated increased odds of hazardous alcohol (AOR = 2.12, 95% CI = 1.41, 3.19) and cannabis use (AOR = 1.61, 95% CI = 1.05, 2.45), psychological distress (AOR = 1.68, 95% CI = 1.14, 2.49), and fair/poor mental health (AOR = 1.70, 95% CI = 1.11, 2.59). Lifetime wr-mTBI demonstrated increased odds of reporting psychological distress (AOR = 3.40, 95% CI = 1.93, 5.97) and fair/poor mental health (AOR = 2.16, 95% CI = 1.12, 4.19) only. CONCLUSIONS: Non-wr-mTBI was associated with both MH and SU, whereas wr-mTBI was associated with MH only. MH outcomes were more strongly associated with wr-mTBI than non-wr-mTBI. Physicians, employers, and insurers need to consider the potential association between wr-mTBI and MH, and provide care accordingly. [ABSTRACT FROM AUTHOR]

Background: Intimate partner violence (IPV) is a global public health crisis, with physical violence leaving IPV survivors at high risk of brain injury (BI). Both BI and IPV have significant physical, psychological, cognitive, and social impacts, including a high risk of mental health concerns, yet there is limited exploration of IPV survivors' experiences with BI and mental health. This study aimed to explore the BI- and mental health-related needs and experiences of IPV survivors from the perspectives of survivors and service providers with the objective of developing knowledge translation materials to raise awareness and support survivors and service providers in addressing these concerns. Methods: This qualitative interpretive description study involved 19 semi-structured interviews and two focus group discussions (2–3 participants each) with 24 participants including IPV survivors experiencing BI and mental health concerns as well as IPV, mental health, and BI service providers between October 2020 and February 2021. Three screening questions were used to identify probable BI among survivors. Participants across groups were an average of 48.5±12.7 years old and were predominantly cisgender women (96%), of European origin (75%), with a university degree (71%). Interviews were recorded, transcribed, and thematically analyzed. Findings: Across interviews, participants spoke about IPV, BI, and mental health as being complex and interrelated experiences that have impacts across the survivor's life and extend well beyond the abusive relationship. Because of the underrecognized nature of BI in IPV, finding and accessing care requires persistence that survivors spoke of as being like "a full-time job." The benefit of making meaningful connections, particularly with other survivors, was highlighted. Conclusions: Recognition of BI as a contributing factor shaping the lived experience of IPV survivors; acknowledgement that the impacts of IPV, BI, and mental health are far reaching and long lasting; and reducing barriers to finding and accessing appropriate care are critical to better supporting IPV survivors with BI and mental health concerns. Clinicians should consider BI and its lingering impacts among the IPV survivors with whom they work. Health and social policy that supports integration of care and the reduction of unnecessary barriers should be a priority. [ABSTRACT FROM AUTHOR]

Financial debt and associated stress might increase the risk of substance use problems or exacerbate existing ones. Little evidence is available about the degree of debt stress and its association with substance use. The objective of this study was to examine the associations of the frequency of worry about debt with heavy episodic drinking (HED), daily smoking, e-cigarette use, and cannabis use in the past 30 days. Data were utilized from the 2020/2022 Monitor study, a repeated cross-sectional survey of adults 18 years and older in Ontario, Canada. The surveys employed a web-based panel survey of 6038 adults and collected data on debt-related stress, HED, tobacco smoking, e-cigarettes, and cannabis use in the past 30 days. Odds ratios (OR) were estimated from logistic regression models accounting for sociodemographic factors. Overall, 18.4% of respondents reported that they were worried about their debt most or all of the time. Accounting for household income, educational status, employment status, and other factors, the results revealed that there was a dose-response relationship between the frequency of worry about debt and substance use including daily smoking, e-cigarette use, and cannabis use in the past 30 days compared to those who were not worried at all about their debt. Sex differences were also found in the association between worry about debt and e-cigarette use. The frequency of worry about debt might have an important role in substance use, which suggests that financial well-being is vital in substance use prevention and harm reduction.

Rising rates of unionization in university settings suggest that campus labour disputes are likely to become an increasingly relevant issue. The research question in the current analysis asked which factors contributed to students' perception of fair treatment following a university labour disruption. A longitudinal survey of students' experiences was conducted before, during, and following a 12-week strike by teaching assistants and contract faculty at a large Canadian university. Hierarchical regression analysis revealed that students' pre-strike satisfaction with their academic program contributed to a perception of post-strike fairness. The more students' plans had been affected by the strike, the greater the reduction in perceived fairness. Post-strike fairness increased significantly the more students were satisfied with course remediation and the more they felt they had a faculty member to turn to following the strike. Interestingly, neither students' levels of financial concern, nor their attitudes toward the strike, predicted perceived fairness. Implications for addressing students' concerns in the wake of an academic labour dispute are discussed. (Contains 5 tables and 2 notes.)
