Socio-demographic factors related to binge drinking in Ontario

Sexual Identity and Heavy Drinking Among Adults in Canada by Racially Minoritized Status and Income, 2015-2020

Purpose: Our objective was to estimate inequities in heavy drinking between heterosexual, gay or lesbian, and bisexual or pansexual individuals, by sex/gender, and to determine whether this association is heterogeneous across racially minoritized status and income groups in Canadians aged 15 and older. Methods: We pooled three Canadian Community Health Survey cycles (2015-2020) and used separate modified Poisson regressions to explore the sex/gender-specific association between sexual identity and heavy drinking prevalence by racially minoritized status, and income, adjusted for survey cycle, age, marital status, and region. Results: With racially minoritized status, and income categories collapsed, heavy drinking was 1.3 times higher (95% confidence interval [CI] = 1.0-1.7) among bisexual or pansexual women compared with heterosexual women, with no differences among men. Among racially minoritized women, heavy drinking was 2.9 (95% CI = 1.3-6.4) times higher among bisexual or pansexual women and 1.9 (95% CI = 0.7-5.2) times higher among gay or lesbian women compared with heterosexual women. Among racially minoritized men, heavy drinking was 1.9 (95% CI = 0.9-4.0) times higher among gay men compared with heterosexual men. No differences were observed across sexual identity in White men or women. Bisexual or pansexual women reported increased heavy drinking relative to heterosexual women across income quintiles. Conclusion: Heavy drinking is distributed heterogeneously across sexual identity, sex/gender, racially minoritized status, and income. These results encourage equity-focused interventions to reduce heavy drinking among intersecting sociodemographic groups experiencing a greater burden of heavy drinking.

Trends in alcohol-attributable hospitalisations and emergency department visits by age, sex, drinking group and health condition in Ontario, Canada

INTRODUCTION

Alcohol-attributable harms are increasing in Canada. We described trends in alcohol-attributable hospitalisations and emergency department (ED) visits by age, sex, drinking group, attribution and health condition.

METHODS

Hospitalisation and ED visits for partially or wholly alcohol-attributable health conditions by age and sex were obtained from population-based health administrative data for individuals aged 15+ in Ontario, Canada. Population-level alcohol exposure was estimated using per capita alcohol sales and alcohol use data. We estimated the number and rate of alcohol-attributable hospitalisations (2008-2018) and ED visits (2008-2019) using the International Model of Alcohol Harms and Policies (InterMAHP).

RESULTS

Over the study period, the modelled rates of alcohol-attributable health-care encounters were higher in males, but increased faster in females. Specifically, rates of alcohol-attributable hospitalisations and ED visits increased by 300% (19-76 per 100,000) and 37% (774-1,064 per 100,000) in females, compared to 20% (322-386 per 100,000) and 2% (2563-2626 per 100,000) in males, respectively. Alcohol-attributable ED visit rates were highest among individuals aged 15-34, however, increased faster among individuals aged 65+ (females: 266%; males: 44%) than 15-34 years (females:+17%; males: -16%). High-volume drinkers had the highest rates of alcohol-attributable health-care encounters; yet, low-/medium-volume drinkers contributed substantial hospitalisations (11%) and ED visits (36%), with increasing rates of ED visits in females drinking low/medium volumes.

DISCUSSION AND CONCLUSIONS

Alcohol-attributable health-care encounters increased overall, and faster among females, adults aged 65+ and low-/medium-volume drinkers. Monitoring trends across subpopulations is imperative to inform equitable interventions to mitigate alcohol-attributable harms.

The association between early onset of alcohol, smokeless tobacco and marijuana use with adult binge drinking in United States

Binge drinking is a deadly pattern of excessive alcohol use that is associated with multiple diseases in the United States. To date, little is known about the associations between the early onset of substance use and other factors with the severity of adult binge drinking. The 2018 National Survey on Drug Use and Health data was used to identify binge drinking (binary and in number of days in the past month). Age at onset was categorized into four groups as 1-12, 13-14, 15-17, or beyond 18. Weighted multivariate logistic regression and Poisson regression analyses were performed to examine the associations between early onset of alcohol, smokeless tobacco, and marijuana use with binge drinking. The severity of binge drinking was statistically significantly associated with substance use (4.15 days in a month), early onset of alcohol, smokeless tobacco, and marijuana use (2.15-4.93 days, all p-values < 0.0001), after accounting for the covariates. Past year substance use disorder is strongly associated with binge drinking. The severity of adult binge drinking is significantly associated with early onset of substance use including alcohol, smokeless tobacco, and marijuana. Continued efforts are warranted to improve substance use prevention and treatment tailored for adolescents and youths to prevent development of adult binge drinking.

Binge drinking in Japan during the COVID-19 pandemic: Prevalence, correlates and association with preventive behaviors

BACKGROUND

There is some evidence that alcohol use may have changed during the coronavirus pandemic. However, as yet, there has been comparatively little focus on heavy/excessive drinking. This study examined binge drinking (BD) in Japan during the coronavirus pandemic and its association with COVID-19 preventive behaviors.

METHOD

Data were analyzed from an online sample of 1452 individuals aged 18 and above that were collected one year after the beginning of the pandemic. Self-reported information was obtained on current and pre-pandemic BD and a range of sociodemographic and health-related variables. Logistic regression analysis was used to examine associations.

RESULTS

Just under one-third of the sample (29.3%) reported past-month BD. More individuals reduced rather than increased BD during the pandemic (11.5% > 6.5%). Worsening household finances and depressive symptoms were associated with both current and increased BD, while young age (18-29) was linked to both increased and decreased BD. Individuals who binged had significantly lower odds for engaging in several COVID-19 preventive behaviors including wearing a mask (odds ratio [OR]: 0.47, 95% confidence interval [CI]: 0.30-0.76), hand washing (OR: 0.58, 95%CI: 0.44-0.76) and avoiding crowds/staying at home (OR: 0.72, 95%CI: 0.55-0.93).

CONCLUSION

BD is prevalent in Japan during the coronavirus pandemic and associated with poorer adherence to COVID-19 preventive behaviors. Increasing public awareness of the potentially detrimental effects of heavy alcohol use during the ongoing pandemic is now a public health priority.
