Introduction: In this study we examined the association of homelessness and emergency department (ED) use, considering social, medical, and mental health factors associated with both homelessness and ED use. We hypothesized that social disadvantage alone could account for most of the association between ED use and homelessness.Methods: We used nationally representative data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III). Emergency department use within the prior year was categorized into no use (27,674; 76.61%); moderate use (1–4 visits: 7,972; 22.1%); and high use (5 or more visits: 475; 1.32%). We used bivariate analyses followed by multivariable-adjusted logistic regression analyses to identify demographic, social, medical, and mental health characteristics associated with ED use.Results: Among 36,121 respondents, unadjusted logistic regression showed prior-year homelessness was strongly associated with moderate and high prior-year ED use (odds ratio[OR] 2.31 and 7.34, respectively, P < 0.001). After adjusting for sociodemographic factors, the associations of homelessness with moderate/high ED use diminished (adjusted OR [AOR] 1.27 and 1.62, respectively, both P < 0.05). Adjusting for medical/mental health variables, alone, similarly diminished the association between homelessness and moderate/high ED use (AOR 1.26, P < .05 and 2.07, P < 0.001, respectively). In a final stepwise model including social and healthvariables, homelessness was no longer significantly associated with moderate or high ED usein the prior year.Conclusion: After adjustment for social disadvantage and health problems, we found no statistically significant association between homelessness and ED use. The implications of our findings suggest that ED service delivery must address both health issues and social factors.

Adolescent gambling is a public health concern and has been linked to suicidality, various risk behaviors, and poor health outcomes. However, there is a limited understanding of specific risk and protective factors that may influence gambling behavior in Connecticut adolescents, especially in changing gambling environments. This study examines relationships between adolescents reporting gambling in the past-year and a range of health risk behaviors including vaping, traumatic experiences, academic performance, and receipt of social support. Data from the 2019 Youth Risk Behavior Survey in Connecticut high school students stratified by gambling status were examined in bivariate and multivariate analyses. Among 1,807 adolescents, past-year gambling was reported by 453 individuals [25.4%; 95% confidence interval [CI] = 22.7–28.1%]. Gambling prevalence was higher among older males and lower in adolescents of Asian origin. Gambling was further associated with suicidality and risk behaviors including substance use, smoking [traditional tobacco and electronic vapor use], risky use of digital technologies, unsafe sex, and aggressive behaviors. Gambling was also associated with traumatic experiences, depression/dysphoria, poor academic performance, and less familial social support. The results provide an up-to-date estimate of the current prevalence and correlates of gambling among Connecticut adolescents. The results provide recent estimates of the prevalence and correlates of gambling among Connecticut adolescents. The findings highlight the need for further investigation of specific factors like social support that help with designing and implementing tailored interventions. [ABSTRACT FROM AUTHOR]
