Numerous studies have established the significant association between tobacco/alcohol usage and mental issues. Smoking tobacco has been linked to a higher risk of developing anxiety disorders and depression. Nicotine, the addictive substance in tobacco, can temporarily alleviate stress and anxiety, but its long-term use can lead to increased anxiety and depression symptoms. Alcohol consumption is also a known factor for both depression and anxiety disorders. Its abuse can disrupt the brain's chemistry, leading to mood swings, increased anxiety and depressive symptoms. However, there has been relatively less focus on understanding how disability status influence the association between tobacco/alcohol usage and mental health. For individuals with disabilities, these risks are often compounded by a range of factors, such as social isolation, poverty, and limited access to healthcare. In this paper, 27,170 participants with/without disability were used to examine the association between tobacco and alcohol usage and mental health outcomes.</span></p></div><div><h3>Objective</h3><p>This cross-sectional study aims to investigate the relationship between tobacco and alcohol use and mental health outcomes among individuals with and without disabilities, using data from the 2020 National Survey on Drug Use and Health (NSDUH).</p></div><div><h3>Methods</h3><p><span>In this study, we conducted bivariate analysis to compare baseline covariates between respondents reporting serious mental issues and those not.

Interventions targeting their adaptive coping in response to IPC events may bolster their emotional security and coping efficacy. However, existing coping interventions have not been tested with children exposed to high post-separation/divorce IPC, nor has any study assessed the effects of individual intervention components on children's coping with IPC and their mental health.

Thus, we examined the association between workplace social capital and mental health among hospital employees using electronic survey data collected from Danish hospital employees. The study sample consisted of 1452 employees, corresponding to 40% of the hospital staff. Mental health was assessed using the Mental Health Continuum Short Form, in which mental health is understood as a combination of emotional, psychological, and social well-being.

Third, mental health was significantly poorer among employees aged between 25 and 35 years than among employees aged between 46 and 55 years. However, unlike our theoretical expectation, linking social capital in relation to the workplace as a whole was not associated with mental health.
