Alcohol Use Among Young Adults in Northern California During the COVID-19 Pandemic-An Electronic Health Records-Based Study.

BackgroundIndividuals globally were affected by the COVID-19 pandemic in myriad of ways, including social isolation and economic hardship, resulting in negative impacts on mental health and substance use. Young adults have been subjected to extraordinary challenges such as job loss, virtual school, or childcare issues, but have received limited attention from research so far.MethodsUsing electronic health record data from a large integrated healthcare system in Northern California, this longitudinal observational study examined changes in the prevalence of unhealthy alcohol use (identified via systematic alcohol screening in adult primary care) from pre- (3/1/2019–12/31/2019) to post-COVID onset (3/1/2020–12/31/2020) among young adults (18–34 years). Among the 663,111 and 627,095 young adults who utilized primary care in the pre- and post-COVID onset periods, 342,889 (51.9%) and 186,711 (29.8%) received alcohol screening, respectively. We fit generalized estimating equation Poisson models to estimate the change in prevalence of unhealthy alcohol use from pre- to post-COVID onset among those who were screened, while using inverse probability weighting to account for potential selection bias of receiving alcohol screening. Heterogeneity in the change of prevalence by patient characteristics was also examined.ResultsOverall, the unadjusted prevalence of unhealthy alcohol use slightly decreased from 9.2% pre-COVID to 9.0% post-COVID onset. After adjusting for patient covariates, the prevalence of unhealthy alcohol use decreased by about 2% [adjusted prevalence ratio (aPR) = 0.98, 95% CI = 0.96, 1.00]. The prevalence of unhealthy alcohol use increased among women by 8% (aPR = 1.08, 95% CI = 1.06, 1.11), patients 18–20 years by 7% (aPR = 1.07, 95% CI = 1.00, 1.15), and Latino/Hispanic patients by 7% (aPR = 1.07, 95% CI = 1.03, 1.11). While the prevalence of unhealthy alcohol use decreased among men by 12% (aPR = 0.88, 95% CI = 0.86, 0.90), patients 21–34 years by 2% (aPR = 0.98, 95% CI = 0.96, 0.99), White patients by 3% (95% CI = 0.95, 1.00), and patients living in neighborhoods with the lowest deprivation indices by 9% (aPR = 0.91, 95% CI = 0.88, 0.94), their unadjusted prevalence remained higher than their counterparts post-COVID onset. There was no variation in the change of prevalence by comorbid mental health conditions or drug use disorders.ConclusionsWhile changes in unhealthy alcohol use prevalence among young adults were small, findings raise concerns over increased drinking among women, those younger than the U.S. legal drinking age, and Latino/Hispanic patients.

Testing the validity of the AUDIT-C and AUDIT-3 to detect unhealthy alcohol use among high-risk populations in Zambia: A secondary analysis from two randomized trials

BackgroundThis study evaluated the test characteristics of brief versions of the Alcohol Use Disorders Identification Test (AUDIT), the AUDIT-C and AUDIT-3, compared to the full AUDIT in populations with heavy drinking living in Zambia and compared differences in effect size estimates when using brief versions in clinical trials. MethodsData were obtained from two randomized trials of the Common Elements Treatment Approach (CETA) for reducing unhealthy alcohol use among adult couples and people living with HIV (PLWH) in Zambia. The full AUDIT was administered to participants at baseline and at 6- or 12-month follow-up. Sensitivity and specificity of the brief versions were calculated in comparison to the full AUDIT. Mixed effects regression models were estimated to calculate the effect sizes from the trials using the brief versions and these were compared to the originally calculated effect sizes using the full version. ResultsThe AUDIT-C performed well at cut-off ≥ 3 for both men (sensitivity: >80%; specificity: >76%) and women (sensitivity: >84%; specificity: >88%). The AUDIT-3 performed best at cut-off ≥ 1, but with comparatively reduced validity for men (sensitivity: >77%; specificity: ≥60%) and women (sensitivity: ≥72%; specificity: >62%). Effect sizes were different by up to 52% using the AUDIT-C and up to 60% for the AUDIT-3 compared to the AUDIT. ConclusionsThe AUDIT-C is recommended as a brief screening tool for community-based and clinic-based screening in Zambia among populations with high prevalence of unhealthy alcohol use. For research studies, the full AUDIT is recommended to calculate treatment effect.

Support for Aboriginal health services in reducing harms from alcohol: 2-year service provision outcomes in a cluster randomized trial.

Background and aimsThere is a higher prevalence of unhealthy alcohol use among Indigenous populations, but there have been few studies of the effectiveness of screening and treatment in primary health care. Over 24 months, we tested whether a model of service‐wide support could increase screening and any alcohol treatment.DesignCluster‐randomized trial with 24‐month implementation (12 months active, 12 months maintenance).SettingAustralian Aboriginal Community Controlled primary care services.ParticipantsTwenty‐two services (83 032 clients) that use Communicare practice software and see at least 1000 clients annually, randomized to the treatment arm or control arm.Intervention and comparatorMulti‐faceted early support model versus a comparator of waiting‐list control (11 services).MeasurementsA record (presence = 1, absence = 0) of: (i) Alcohol Use Disorders Identification Test—Consumption (AUDIT‐C) screening (primary outcome), (ii) any‐treatment and (iii) brief intervention. We received routinely collected practice data bimonthly over 3 years (1‐year baseline, 1‐year implementation, 1‐year maintenance). Multi‐level logistic modelling was used to compare the odds of each outcome before and after implementation.FindingsThe odds of being screened within any 2‐month reference period increased in both arms post‐implementation, but the increase was nearly eight times greater in early‐support services [odds ratio (OR) = 7.95, 95% confidence interval (CI) = 4.04–15.63, P < 0.001]. The change in odds of any treatment in early support was nearly double that of waiting‐list controls (OR = 1.89, 95% CI = 1.19–2.98, P = 0.01) but was largely driven by decrease in controls. There was no clear evidence of difference between groups in the change in the odds of provision of brief intervention (OR = 1.95, 95% CI = 0.53–7.17, P = 0.32).ConclusionsAn early support model designed to aid routine implementation of alcohol screening and treatment in Aboriginal health services resulted in improvement of Alcohol Use Disorders Identification Test—Consumption screening rates over 24 months of implementation, but the effect on treatment was less clear.

Frequency of Hazardous and Binge Drinking Alcohol Among Hospitalized Cardiovascular Patients

Excessive alcohol use is a risk factor for most cardiac diseases. The prevalence of unhealthy alcohol use among hospitalized cardiac patients is uncertain as is the frequency with which it is addressed. We performed a single center, patient-level anonymous survey among hospitalized cardiac patients eligible for cardiac rehabilitation. Hazardous drinking was defined as an Alcohol Use Disorders Identification Test (AUDIT) score of 8 or greater. Binge drinking was defined as 5+ drinks for men or 4+ for women on ≥1 occasion within the past 30 days. Unhealthy drinking was defined as either hazardous or binge drinking. Of 300 patients approached, 290 (96.7%) completed the survey. Mean ( ± SD) age was 69 ± 11 years; 70% were male and 31% were cardiac surgical patients. The proportion (95% CI) of hazardous, binge, and unhealthy drinking was 12% (9 to 16), 16% (12 to 20), and 18% (14-23), respectively. Overall, 58% of subjects reported being screened for alcohol use, mostly by nurses (56%). Those with unhealthy drinking reported being counseled more frequently about their alcohol use compared to non-unhealthy drinkers (11% versus 3%, p=0.03), but the large majority (89%) of unhealthy drinkers reported receiving no advice about their alcohol use while admitted. In conclusion, almost one-fifth of hospitalized cardiac patients reported unhealthy drinking, these patients were only screened about half of the time, and were rarely counseled about their alcohol use.

Association of Bariatric Surgical Procedures With Changes in Unhealthy Alcohol Use Among US Veterans

Bariatric surgical procedures have been associated with increased risk of unhealthy alcohol use, but no previous research has evaluated the long-term alcohol-related risks after laparoscopic sleeve gastrectomy (LSG), currently the most used bariatric procedure. No US-based study has compared long-term alcohol-related outcomes between patients who have undergone Roux-en-Y gastric bypass (RYGB) and those who have not. To evaluate the changes over time in alcohol use and unhealthy alcohol use from 2 years before to 8 years after a bariatric surgical procedure among individuals with or without preoperative unhealthy alcohol use. This retrospective cohort study analyzed electronic health record (EHR) data on military veterans who underwent a bariatric surgical procedure at any of the bariatric centers in the US Department of Veterans Affairs (VA) health system between October 1, 2008, and September 30, 2016. Surgical patients without unhealthy alcohol use at baseline were matched using sequential stratification to nonsurgical control patients without unhealthy alcohol use at baseline, and surgical patients with unhealthy alcohol use at baseline were matched to nonsurgical patients with unhealthy alcohol use at baseline. Data were analyzed in February 2020. LSG (n = 1684) and RYGB (n = 924). Mean alcohol use, unhealthy alcohol use, and no alcohol use were estimated using scores from the validated 3-item Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), which had been documented in the VA EHR. Alcohol outcomes were estimated with mixed-effects models. A total of 2608 surgical patients were included in the final cohort (1964 male [75.3%] and 644 female [24.7%] veterans. Mean (SD) age of surgical patients was 53.0 (9.9) years and 53.6 (9.9) years for the matched nonsurgical patients. Among patients without baseline unhealthy alcohol use, 1539 patients who underwent an LSG were matched to 14 555 nonsurgical control patients and 854 patients who underwent an RYGB were matched to 8038 nonsurgical control patients. In patients without baseline unhealthy alcohol use, the mean AUDIT-C scores and the probability of unhealthy alcohol use both increased significantly 3 to 8 years after an LSG or an RYGB, compared with control patients. Eight years after an LSG, the probability of unhealthy alcohol use was higher in surgical vs control patients (7.9% [95% CI, 6.4-9.5] vs 4.5% [95% CI, 4.1-4.9]; difference, 3.4% [95% CI, 1.8-5.0])). Similarly, 8 years after an RYGB, the probability of unhealthy alcohol use was higher in surgical vs control patients (9.2% [95% CI, 8.0-10.3] vs 4.4% [95% CI, 4.1-4.6]; difference, 4.8% [95% CI, 3.6-5.9]). The probability of no alcohol use also decreased significantly 5 to 8 years after both procedures for surgical vs control patients. Among patients with unhealthy alcohol use at baseline, prevalence of unhealthy alcohol use was higher for patients who underwent an RYGB than matched controls. In this multi-site cohort study of predominantly male patients, among those who did not have unhealthy alcohol use in the 2 years before bariatric surgery, the probability of developing unhealthy alcohol use increased significantly 3-8 years after bariatric procedures compared with matched controls during follow-up.

The Kaiser Permanente Northern California Adult Alcohol Registry, an Electronic Health Records-Based Registry of Patients With Alcohol Problems: Development and Implementation.

BackgroundElectronic health record (EHR)–based disease registries have aided health care professionals and researchers in increasing their understanding of chronic illnesses, including identifying patients with (or at risk of developing) conditions and tracking treatment progress and recovery. Despite excessive alcohol use being a major contributor to the global burden of disease and disability, no registries of alcohol problems exist. EHR-based data in Kaiser Permanente Northern California (KPNC), an integrated health system that conducts systematic alcohol screening, which provides specialty addiction medicine treatment internally and has a membership of over 4 million members that are highly representative of the US population with access to care, provide a unique opportunity to develop such a registry.ObjectiveOur objectives were to describe the development and implementation of a protocol for assembling the KPNC Adult Alcohol Registry, which may be useful to other researchers and health systems, and to characterize the registry cohort descriptively, including underlying health conditions.MethodsInclusion criteria were adult members with unhealthy alcohol use (using National Institute on Alcohol Abuse and Alcoholism guidelines), an alcohol use disorder (AUD) diagnosis, or an alcohol-related health problem between June 1, 2013, and May 31, 2019. We extracted patients’ longitudinal, multidimensional EHR data from 1 year before their date of eligibility through May 31, 2019, and conducted descriptive analyses.ResultsWe identified 723,604 adult patients who met the registry inclusion criteria at any time during the study period: 631,780 with unhealthy alcohol use, 143,690 with an AUD diagnosis, and 18,985 with an alcohol-related health problem. We identified 65,064 patients who met two or more criteria. Of the 4,973,195 adult patients with at least one encounter with the health system during the study period, the prevalence of unhealthy alcohol use was 13% (631,780/4,973,195), the prevalence of AUD diagnoses was 3% (143,690/4,973,195), and the prevalence of alcohol-related health problems was 0.4% (18,985/4,973,195). The registry cohort was 60% male (n=432,847) and 41% non-White (n=295,998) and had a median age of 41 years (IQR=27). About 48% (n=346,408) had a chronic medical condition, 18% (n=130,031) had a mental health condition, and 4% (n=30,429) had a drug use disorder diagnosis.ConclusionsWe demonstrated that EHR-based data collected during clinical care within an integrated health system could be leveraged to develop a registry of patients with alcohol problems that is flexible and can be easily updated. The registry’s comprehensive patient-level data over multiyear periods provides a strong foundation for robust research addressing critical public health questions related to the full course and spectrum of alcohol problems, including recovery, which would complement other methods used in alcohol research (eg, population-based surveys, clinical trials).

Unhealthy Alcohol Use

Unhealthy alcohol use refers to a spectrum of alcohol consumption ranging from at-risk drinking to alcohol use disorder. It is associated with both a high cost to society and to individuals. Globally, alcohol is a leading cause of death and disability, and despite the high prevalence of unhealthy alcohol use, diagnosis, and treatment of alcohol use disorder remains disproportionately low. Risk for unhealthy alcohol use and alcohol related harms is multifactorial and includes genetic factors, gender, age, socioeconomic status, cultural and societal norms, and policies regulating alcohol consumption among others. Excessive alcohol use is associated with a myriad of poor physical and mental health outcomes, and screening for unhealthy alcohol use is universally recommended and effective. This review contains 1 figures, 2 tables, and 76 references. Key Words: addiction, alcohol, cancer, diagnosis, drinking, liver disease, screening, stigma, use disorderImportant Advances

Use of web-based screening and brief intervention for unhealthy alcohol use by older adults

BackgroundWhile the number of older adults who engage in unhealthy drinking is increasing, few studies have examined the role of online alcohol screening and intervention tools for this population. The objective of this study was to describe characteristics of drinking behaviors among older adults who visited an alcohol screening and intervention website, and compare them to younger adults. MethodsWe analyzed the responses of visitors to Alcoholscreening.org in 2013 (n=94,221). The prevalence of unhealthy alcohol use, behavioral change characteristics, and barriers to changing drinking were reported by age group (ages 21–49, 50–65, 66–80). Logistic regression models were used to identify characteristics associated with receiving a plan to either help cut back or quit drinking. ResultsOf the entire study sample, 83% of respondents reported unhealthy drinking (exceeding daily or weekly recommended limits) with 84% among 21–49year olds, 79% among 50–65year olds, and 85% among adults over 65. Older adults reported fewer negative aspects of drinking, lower importance to change, highest confidence and fewer barriers to change, compared to younger adults. In the adjusted model, females (AOR=1.45, p<0.001) and older adults (AOR=1.55, p<0.002) were more likely to receive a plan to change drinking behaviors. DiscussionAn online screening and intervention tool identified many older adults with unhealthy alcohol use behaviors and most were receptive to change. Web-based screening and interventions for alcohol use have the potential to be widely used among older adults.

High prevalence of unhealthy alcohol use and comparison of self-reported alcohol consumption to phosphatidylethanol among women engaged in sex work and their male clients in Cambodia

BackgroundIn Cambodia, most of the female sex workers (FSW) work in venues where unhealthy alcohol use is ubiquitous and potentially contributing to the HIV epidemic. However, no accurate data exists. We compare self-reported unhealthy alcohol consumption to a biomarker of alcohol intake in Cambodian FSW and male clients, and determine factors associated with unhealthy alcohol use. MethodsA cross-sectional study was conducted among FSW (n=100) and male clients (n=100) in entertainment and sex work venues in Cambodia. Self-reported unhealthy alcohol use (AUDIT-C) was compared to phosphatidylethanol (PEth) positive (≥50ng/ml), a biomarker of alcohol intake. Sociodemographics data was collected. Correlates of self-reported unhealthy alcohol use and PEth positive were determined. ResultsThe prevalence of PEth positive in FSW was 60.0%. Self-reported unhealthy alcohol consumption was reported by 85.0% of the women. Almost all women (95.0%) testing PEth positive also reported unhealthy alcohol use. Prevalence of unhealthy alcohol consumption (self-report and PEth positive) was higher in FSW working in entertainment establishments compared to other sex work venues (p<0.01). Among male clients, 47.0% reported unhealthy alcohol consumption and 42.0% had a PEth positive. However, only 57.1% of male clients with PEth positive reported unhealthy alcohol use. ConclusionsUnhealthy alcohol consumption is prevalent in Cambodian sex work settings. Self-reported unhealthy alcohol use is well reported by FSW, but less by male clients. These findings highlight the urgency of using accurate measures of unhealthy alcohol consumption and integrating this health issue into HIV prevention interventions.

The Impact of a Mandated Trauma Center Alcohol Intervention on Readmission and Cost per Readmission in Arizona.

Persons appearing in trauma centers have a higher prevalence of unhealthy alcohol use than the general population. Screening and brief intervention (SBI) is designed to moderate drinking levels and avoid costly future readmissions, but few studies have examined the impact of SBI on hospital readmissions and health care costs in a trauma population. This study uses comparative interrupted time-series and the Arizona State Inpatient Database to estimate the effect of the American College of Surgeons Committee on Trauma SBI mandate on the probability of readmission and cost per readmission in Arizona trauma centers. We compare individuals with and without an alcohol diagnosis code before and after the mandate was implemented. The mandate resulted in a 2.2 percentage point reduction (44%) in the probability of readmission. Total health care and readmission costs were not affected by the mandate. The estimates are consistent with a differential effect of SBI: SBI reduces readmissions among those who present with a less serious alcohol-related problem. Persons with more serious alcohol problems are less likely to respond to SBI. These higher risk individuals likely have a higher cost, which may explain the lack of change in readmission costs. Our study is a macrolevel intent-to-treat analysis of SBI's impact that corroborates the potential of SBI implied by efficacy studies in trauma centers and other settings. This study provides a framework for future research involving more states and health systems and evaluating other SBI policies.

Alcohol Consumption among Students--A Cross-Sectional Study at Three Largest Universities in Serbia.

The prevalence of unhealthy alcohol use among university students is increasing in many countries. The aim of the study was to investigate alcohol consumption and alcohol-related knowledge, attitudes and risky behaviors among Serbian university students. The cross-sectional study was carried out at the three state universities from January to June in the academic year 2009/2010 and included 2,285 students of both genders. The students filled out a questionnaire consisting of 70 questions with respect to demographic and socioeconomic characteristics, their lifestyle habits, styles and attitudes, health assessment, as well as exposure to different risk factors. It was found that 77.7% of students drank alcohol occasionally, 4.6% of them consumed it on a daily basis. Friedman's test (p < 0.001) showed that students prefer drinking beer to all other alcoholic beverages. Students in Belgrade and students of Technical faculties are undisputed champions when it comes to how often they drink six or more drinks on a single occasion. Older students in Serbia drink more and get drunk more frequently. A high percentage of Serbian students consume alcohol, and even though they have their first drink at an early age, they generally drink less than students in many other countries.

Prevalence of unhealthy alcohol use in hospital outpatients

BackgroundFew studies have examined the prevalence of unhealthy alcohol use in the hospital outpatient setting. Our aim was to estimate the prevalence of unhealthy alcohol use among patients attending a broad range of outpatient clinics at a large public hospital in Australia. MethodsAdult hospital outpatients were invited to complete the Alcohol Use Disorders Identification Test Consumption questions (AUDIT-C) using an iPad as part of a randomised trial testing the efficacy of alcohol electronic screening and brief intervention. Unhealthy alcohol use was defined as an AUDIT-C score ≥5 among men and ≥4 among women. ResultsSixty percent (3616/6070) of invited hospital outpatients consented, of whom 89% (3206/3616) provided information on their alcohol consumption (either reported they had not consumed any alcohol in the last 12 months or completed the AUDIT-C). The prevalence of unhealthy alcohol use was 34.7% (95% confidence interval [CI]: 33.0–36.3%). The prevalence among men aged 18–24 years, 25–39 years, 40–59 years and 60 years and older, was 74.4% (95% CI: 68.4–80.4%), 54.3% (95% CI: 48.7–59.8%), 44.1% (95% CI: 39.9–48.3%), and 27.0% (95% CI: 23.6–30.4%), respectively (43.1% overall; 95% CI: 40.8–45.5%). The prevalence among women aged 18–24 years, 25–39 years, 40–59 years, and 60 years and older, was 48.6% (95% CI: 39.2–58.1%), 36.9% (95% CI: 31.2–42.6%), 25.2% (95% CI: 21.5–29.0%) and 14.5% (95% CI: 11.7–17.3%), respectively (24.9% overall; 95% CI: 22.7–27.1%). ConclusionA large number of hospital outpatients who are not currently seeking treatment for their drinking could benefit from effective intervention in this setting.

Alcohol Consumption Among Urban, Suburban, and Rural Veterans Affairs Outpatients

United States rural residents tend toward poorer health than urban residents. Although alcohol use is associated with multiple medical conditions and can be reduced via brief primary care-based interventions, it is unknown whether alcohol consumption differs by rurality among primary care patients. We sought to describe alcohol consumption among urban, suburban, and rural Veterans Affairs (VA) outpatients. Outpatients from 7 VA facilities responded to mailed surveys that included the validated Alcohol Use Disorders Identification Test Consumption (AUDIT-C) screening questionnaire. The ZIP code approximation of the US Department of Agriculture's rural-urban commuting area (RUCA) codes classified participants into urban, suburban, and rural areas. For each area, adjusted logistic regression models estimated the prevalence of past-year abstinence among all participants and unhealthy alcohol use (AUDIT-C ≥ 3 for women and ≥ 4 for men) among drinkers. Among 33,883 outpatients, 14,967 (44%) reported abstinence. Among 18,916 drinkers, 8,524 (45%) screened positive for unhealthy alcohol use. The adjusted prevalence of abstinence was lowest in urban residents (43%, 95% CI 42%-43%) with significantly higher rates in both suburban and rural residents [45% (44%-46%) and 46% (45%-47%), respectively]. No significant differences were observed in the adjusted prevalence of unhealthy alcohol use among drinkers. Abstinence is slightly more common among rural and suburban than urban VA outpatients, but unhealthy alcohol use does not vary by rurality. As the VA and other health systems implement evidence-based care for unhealthy alcohol use, more research is needed to identify whether preventive strategies targeted to high-risk areas are needed.

Cost‐Effectiveness of Screening for Unhealthy Alcohol Use with %Carbohydrate Deficient Transferrin: Results From a Literature‐Based Decision Analytic Computer Model

The %carbohydrate deficient transferrin (%CDT) test offers objective evidence of unhealthy alcohol use but its cost-effectiveness in primary care conditions is unknown. Using a decision tree and Markov model, we performed a literature-based cost-effectiveness analysis of 4 strategies for detecting unhealthy alcohol use in adult primary care patients: (i) Questionnaire Only, using a validated 3-item alcohol questionnaire; (ii) %CDT Only; (iii) Questionnaire followed by %CDT (Questionnaire-%CDT) if the questionnaire is negative; and (iv) No Screening. For those patients screening positive, clinicians performed more detailed assessment to characterize unhealthy use and determine therapy. We estimated costs using Medicare reimbursement and the Medical Expenditure Panel Survey. We determined sensitivity, specificity, prevalence of disease, and mortality from the medical literature. In the base case, we calculated the incremental cost-effectiveness ratio (ICER) in 2006 dollars per quality-adjusted life year ($/QALY) for a 50-year-old cohort. In the base case, the ICER for the Questionnaire-%CDT strategy was $15,500/QALY compared with the Questionnaire Only strategy. Other strategies were dominated. When the prevalence of unhealthy alcohol use exceeded 15% and screening age was <60 years, the Questionnaire-%CDT strategy costs less than $50,000/QALY compared to the Questionnaire Only strategy. Adding %CDT to questionnaire-based screening for unhealthy alcohol use was cost-effective in our literature-based decision analytic model set in typical primary care conditions. Screening with %CDT should be considered for adults up to the age of 60 when the prevalence of unhealthy alcohol use is 15% or more and screening questionnaires are negative.

Unhealthy Drinking Patterns in Older Adults: Prevalence and Associated Characteristics

To examine the prevalence of unhealthy drinking patterns in community-dwelling older adults and its association with sociodemographic and health characteristics. Cross-sectional analysis of nationally representative survey data. The data source was the 2003 Access to Care file of the Medicare Current Beneficiary Survey, which represents the continuously enrolled Medicare population. Community-dwelling Medicare beneficiaries aged 65 and older (N=12,413). The prevalence of unhealthy alcohol use by older adults defined in relation to two parameters of recommended limits: monthly use exceeding 30 drinks per typical month and "heavy episodic" drinking of four or more drinks in any single day during a typical month in the previous year. Sociodemographic and health status variables were also included. Nine percent of elderly Medicare beneficiaries reported unhealthy drinking, with higher prevalence in men (16%) than women (4%). In logistic regression analyses with the full sample, higher education and income; better health status; male sex; younger age; smoking; being white; and being divorced, separated, or single were associated with higher likelihood of unhealthy drinking. Among drinkers, in addition to sociodemographic variables, self-reported depressive symptoms were positively associated with unhealthy drinking. Among unhealthy drinkers, race and ethnicity variables were associated with likelihood of heavy episodic drinking. Almost one in 10 elderly Medicare beneficiaries report exceeding recommended drinking limits. Several distinct unhealthy drinking patterns were identified and associated with sociodemographic and health characteristics, suggesting the value of additional targeted approaches within the context of universal screening to reduce alcohol misuse by older adults.
