Association of Alcohol Screening Scores With Adverse Mental Health Conditions and Substance Use Among US Adults

The Disease Model of Addiction: The Impact of Genetic Variability in the Oxidative Stress and Inflammation Pathways on Alcohol Dependance and Comorbid Psychosymptomatology

Oxidative stress and neuroinflammation are involved in the pathogenesis of alcohol addiction. However, little is known regarding the effect of genetic, behavioral, psychological, and environmental sources of origin on the inflammation and oxidative stress pathways of patients with alcohol addiction. Our study aimed to evaluate the impact of selected common functional single-nucleotide polymorphisms in inflammation and oxidative stress genes on alcohol addiction, and common comorbid psychosymptomatology. Our study included 89 hospitalized alcohol-addicted patients and 93 healthy individuals, all Slovenian males. Their DNA was isolated from peripheral blood and patients were genotyped for PON1 rs705379, rs705381, rs854560, and rs662, SOD2 rs4880, GPX1 rs1050450, IL1B rs1143623, rs16944, and rs1071676, IL6 rs1800795, IL6R rs2228145, and miR146a rs2910164. Kruskal-Wallis and Mann-Whitney tests were used for the additive and dominant genetic models, respectively. Our findings suggested the involvement of IL6 rs1800795 in alcohol addiction. Moreover, our data indicated that the genetic variability of SOD2 and PON1, as well as IL1B and IL6R, may be related to comorbid psychosymptomatology, revealing a potential indirect means of association of both the oxidative stress and inflammation pathways.

Dementias Among Older Males and Females in the U.S. Medicare System With and Without HIV

BACKGROUND

Despite the growing concern that people with HIV (PWH) will experience a disproportionate burden of dementia as they age, very few studies have examined the sex-specific prevalence of dementia, including Alzheimer disease and related dementias (AD/ADRD) among older PWH versus people without HIV (PWOH) using large national samples.

METHODS

We constructed successive cross-sectional cohorts including all PWH aged 65+ years from U.S. Medicare enrollees and PWOH in a 5% national sample of Medicare data from 2007 to 2019. All AD/ADRD cases were identified by ICD-9-CM/ICD-10-CM diagnosis codes. Prevalence of AD/ADRD was calculated for each calendar year by sex-age strata. Generalized estimating equations were used to assess factors associated with dementia and calculate the adjusted prevalence.

RESULTS

PWH had a higher prevalence of AD/ADRD, which increased over time compared with PWOH, especially among female beneficiaries and with increasing age. For example, among those aged 80+ years, the prevalence increased from 2007 to 2019 (females with HIV: 31.4%-44.1%; females without HIV: 27.4%-29.9%; males with HIV: 26.2%-33.3%; males without HIV: 21.0%-23.5%). After adjustment for demographics and comorbidities, the differences in dementia burden by HIV status remained, especially among older age groups.

CONCLUSIONS

Older Medicare enrollees with HIV had an increased dementia burden over time compared with those without HIV, especially women and older subjects. This underscores the need to develop tailored clinical practice guidelines that facilitate the integration of dementia and comorbidity screening, evaluation, and management into the routine primary care of aging PWH.

Maternal depression, alcohol use, and transient effects of perinatal paraprofessional home visiting in South Africa: Eight-year follow-up of a cluster randomized controlled trial

BACKGROUND

South African mothers confront synergistic challenges from depression, alcohol use, and HIV/AIDS. The importance of maternal functioning for child development motivates interventions, yet long-term outcomes seldom are tracked. Furthermore, little is known about trajectories and the role of social-cultural factors in maternal depression and alcohol use across parenthood in low- and middle-income countries.

METHODS

We examined maternal outcomes at 5- and 8-years' post-birth, from the Philani Intervention Program (PIP), a randomized controlled trial of a prenatally-initiated home visiting intervention lasting through 6 months' post-birth which yielded some benefits for children and mothers through 3 years. Longitudinal Bayesian mixed-effects models assessed intervention effects for maternal depression and alcohol use from pre-birth through 8 years post-birth. We plotted trajectories of depression and alcohol use and analyzed their relationship over time.

RESULTS

Maternal benefits appeared limited and intervention outcomes differed at 5 and 8 years. Reduced depression in PIP versus standard care (SC) mothers at 3 years disappeared by 5 and 8 years. Depression prevalence declined from 35.1% prenatally to 5.5% at 8 years, independent of intervention or alcohol use. Alcohol use in both groups rebounded from a post-birth nadir; fewer PIP than SC mothers drank alcohol and reported problematic use at 5 but not 8 years. HIV+ prevalence did not differ by condition and increased from 26% to 45% over the reported period.

CONCLUSIONS

Dissipation of early child benefits from home visiting by age 8 years likely reflects lack of durable change in maternal behaviors compounded by social-cultural factors and cumulative effects of community deprivation. High prenatal rates warrant screening and treatment for depression in standard antenatal care. Low-and-middle income countries may need sustained interventions, including alcohol use reduction, to capitalize on initial gains from targeted interventions and address community social-cultural factors. HIV/AIDS continues to spread in this population.

Assessing incident depression among older people with and without HIV in U.S

PURPOSE

Despite substantially higher prevalence of depression among people living with HIV/AIDS (PLWHA), few data exist on the incidence and correlates of depression in this population. This study assessed the effect of HIV infection, age, and cohort period on the risk of developing depression by sex among older U.S. Medicare beneficiaries.

METHODS

We constructed a retrospective matched cohort using a 5% nationally representative sample of Medicare beneficiaries (1996-2015). People with newly diagnosed (n = 1309) and previously diagnosed (n = 1057) HIV were individually matched with up to three beneficiaries without HIV (n = 6805). Fine-Gray models adjusted for baseline covariates were used to assess the effect of HIV status on developing depression by sex strata.

RESULTS

PLWHA, especially females, had higher risk of developing depression within five years. The relative subdistribution hazards (sHR) for depression among three HIV exposure groups differed between males and females and indicated a marginally significant interaction (p = 0.08). The sHR (95% CI) for newly and previously diagnosed HIV (vs. people without HIV) were 1.6 (1.3, 1.9) and 1.9 (1.5, 2.4) for males, and 1.5 (1.2, 1.8) and 1.2 (0.9, 1.7) for females. The risk of depression increased with age [sHR 1.3 (1.1, 1.5), 80 + vs. 65-69] and cohort period [sHR 1.3 (1.1, 1.5), 2011-2015 vs. 1995-2000].

CONCLUSIONS

HIV infection increased the risk of developing depression within 5 years, especially among people with newly diagnosed HIV and females. This risk increased with older age and in recent HIV epidemic periods, suggesting a need for robust mental health treatment in HIV primary care.

Cessation of self-reported opioid use and impacts on co-occurring health conditions

BACKGROUND

Among veterans in care reporting opioid use, we investigated the association between ceasing opioid use on subsequent reduction in report of other substance use and improvements in pain, anxiety, and depression.

METHODS

Using Veterans Aging Cohort Study survey data collected between 2003 and 2012, we emulated a hypothetical randomized trial (target trial) of ceasing self-reported use of prescription opioids and/or heroin, and outcomes including unhealthy alcohol use, smoking, cannabis use, cocaine use, pain, and anxiety and depressive symptoms. Among those with baseline opioid use, we compared participants who stopped reporting opioid use at the first follow-up (approximately 1 year after baseline) with those who did not. We fit logistic regression models to estimate associations with change in each outcome at the second follow-up (approximately 2 years after baseline) among participants with that condition at baseline. We examined two sets of adjusted models that varied temporality assumptions.

RESULTS

Among 2473 participants reporting opioid use, 872 did not report use, 606 reported use, and 995 were missing data on use at the first follow-up. Ceasing opioid use was associated with no longer reporting cannabis (adjusted odds ratio [AOR]=1.82, 95% confidence interval [CI] 1.10, 3.03) and cocaine use (AOR=1.93, 95% CI 1.16, 3.20), and improvements in pain (AOR=1.53, 95% CI 1.05, 2.24) and anxiety (AOR=1.56, 95% CI 1.01, 2.41) symptoms.

CONCLUSION

Cessation of opioid misuse may be associated with subsequent cessation of other substances and reduction in pain and anxiety symptoms, which supports efforts to screen and provide evidence-based intervention where appropriate.

Incident depression among Medicare beneficiaries with disabilities and HIV

OBJECTIVE

Despite disproportionally high prevalence of HIV and depression in persons with disabilities, no data have been published on the incidence and correlates of depression in Medicare beneficiaries with disabilities. We assessed the effect of HIV infection on developing depression in this population.

DESIGN

We conducted a retrospective matched cohort study using a 5% sample of Medicare beneficiaries who qualified for disability coverage (1996-2015).

METHODS

Beneficiaries with incident ( n  = 2438) and prevalent ( n  = 5758) HIV were individually matched with beneficiaries without HIV (HIV-, n  = 20 778). Fine-Gray models with death as a competing risk were used to assess the effect of HIV status, age, and cohort period on developing depression by sex strata.

RESULTS

Beneficiaries with HIV had a higher risk of developing depression within 5 years ( P  < 0.0001). Sex differences were observed ( P  < 0.0001), with higher subdistribution hazard ratios (sHR) in males with HIV compared with controls. The risk decreased with age ( P  < 0.0001) and increased in recent years ( P  < 0.0001). There were significant age-HIV ( P  = 0.004) and period-HIV ( P  = 0.006) interactions among male individuals, but not female individuals. The sHR was also higher within the first year of follow-up among male individuals, especially those with incident HIV.

CONCLUSION

Medicare enrollees with disabilities and HIV had an increased risk of developing depression compared to those without HIV, especially among males and within the first year of HIV diagnosis. The HIV-depression association varied by sex, age, and cohort period. Our findings may help guide screening and comprehensive management of depression among subgroups in this vulnerable population.

Screening, Diagnosis, and Treatment of Alcohol-Related Liver Disease and Alcohol-Associated Hepatitis

Alcohol-related liver disease is a spectrum of disease in which continued, significant alcohol use can cause progression from fatty changes in the liver to inflammation, fibrosis, and eventually cirrhosis. The rates of alcohol consumption, alcohol use disorder, and alcoholrelated liver disease have increased substantially during the past several years. However, the amount of alcohol consumption may not be the only risk factor for such progression of disease. Studies have found several other risk factors, including sex, race, and genetic predisposition, as possible culprits of worsening disease. As a result, clinicians must understand and implement screening tools for early diagnosis and remain up-to-date with the evolving nature of treatment options. This article reviews the diagnosis and treatment of alcohol use disorder as well as the pathophysiology, clinical presentation, and treatment of alcohol-related liver disease, including alcohol-associated hepatitis.

Substance use disorders among primary care patients screening positive for unhealthy alcohol use

BACKGROUND

Despite high prevalence of polysubstance use, recent data on concurrent alcohol use in patients with specific substance use disorders (SUDs) are lacking.

OBJECTIVE

To examine associations between specific SUDs and alcohol consumption levels.

METHODS

Using electronic health record data, we conducted a cross-sectional study of 2,720,231 primary care adults screened for alcohol use between 2014 and 2017 at Kaiser Permanente Northern California. Alcohol consumption levels were categorized as no reported use, low-risk use, and unhealthy use (exceeding daily, weekly, or both recommended drinking limits). Using multinomial logistic regression, and adjusting for sociodemographic and health characteristics, we examined the odds of reporting each alcohol consumption level in patients with a prior-year SUD diagnosis (alcohol, cannabis, cocaine, inhalant, opioid, sedative/anxiolytic, stimulant, other drug, nicotine, any SUD except nicotine) compared to those without.

RESULTS

The sample was 52.9% female, 48.1% White; the mean age was 46 years (SD = 18). Patients with SUDs were less likely to report low-risk alcohol use relative to no use compared with patients without SUDs. Patients with alcohol or nicotine use disorder had higher odds of reporting unhealthy alcohol use relative to no use; however, patients with all other SUDs (except cocaine) had lower odds. Among patients who reported any alcohol use (n = 861,427), patients with SUDs (except opioid) had higher odds of exceeding recommended limits than those without.

CONCLUSION

The associations of unhealthy alcohol use and SUDs suggest that screening for both alcohol and drug use in primary care presents a crucial opportunity to prevent and treat SUDs early.

The Association Between Alcohol-Related Problems and Sleep Quality and Duration Among College Students: a Multicountry Pooled Analysis

Alcohol consumption and sleep disorders are both prevalent and relevant problems among college students, but the relationship between these conditions is unclear. This study aimed to analyze the association between alcohol-related problems and sleep in first-year college students from Brazil, Chile, and Spain. Cross-sectional analyses were performed with data from three independent studies with first-year college students from each country. The risk of alcohol-related problems (RARP) and sleep quality and duration were self-reported using mixed methods. Pooled odds ratios (p-OR) and 95% confidence intervals (95% CI) of suboptimal sleep quality and of short (< 7 h) and long (> 8 h) sleep duration were estimated according to RARP adjusting for the main confounders. Of the 1830 students included (31.2% Brazilian, 42.2% Chilean, and 26.6% Spanish), 61.6% were female, and the mean age was 20.0 ± 3.6 years. Overall, 25.0% and 9.9% of the students were classified as intermediate and high RARP, respectively. In the combined results for the three countries, intermediate-to-high RARP was associated with a higher likelihood of suboptimal sleep quality (p-OR: 1.24; 95% CI: 1.00 to 1.52; I2 heterogeneity statistics: 43.0%), regardless of sociodemographic and lifestyle covariates and of self-rated health. The frequency of alcohol consumption was not associated with sleep quality or sleep duration. In this multicountry pooled analysis, first-year college students at risk of alcohol-related problems were more likely to report worse sleep quality. The coexistence of alcohol-related problems and sleep disorders could potentiate its adverse health effects among these young adults.

Integrating Screening and Treatment of Unhealthy Alcohol Use and Depression with Screening and Treatment of Anxiety, Pain, and Other Substance Use Among People with HIV and Other High-Risk Persons

We review and synthesize results from a series of analyses estimating the benefit of screening for unhealthy alcohol use, depression, and tobacco to detect individuals at heightened risk for co-occurring anxiety, pain, depression, unhealthy alcohol use, and other substance use among people with HIV and HIV-uninfected individuals in the Veterans Aging Cohort Study. We also examine the potential impact of reducing unhealthy alcohol use and depressive symptoms on the incidence of co-occurring conditions. We found that screening for alcohol and depression may help identify co-occurring symptoms of anxiety, depression, and pain interference, treating unhealthy alcohol use may improve co-occurring pain interference and substance use, and improving depressive symptoms may improve co-occurring anxiety, pain interference, and smoking. We propose that an integrated approach to screening and treatment for unhealthy alcohol use, depression, anxiety, pain, and other substance use may facilitate diagnostic assessment and treatment of these conditions, improving morbidity and mortality.

Substance use and mental health burden in head and neck and other cancer survivors: A National Health Interview Survey analysis

BACKGROUND

Tobacco dependence, alcohol abuse, depression, distress, and other adverse patient-level influences are common in head and neck cancer (HNC) survivors. Their interrelatedness and precise burden in comparison with survivors of other cancers are poorly understood.

METHODS

National Health Interview Survey data from 1997 to 2016 were pooled. The prevalence of adverse patient-level influences among HNC survivors and matched survivors of other cancers were compared using descriptive statistics. Multivariable logistic regressions evaluating covariate associations with the primary study outcomes were performed. These included 1) current cigarette smoking and/or heavy alcohol use (>14 drinks per week) and 2) high mental health burden (severe psychological distress [Kessler Index ≥ 13] and/or frequent depressive/anxiety symptoms).

RESULTS

In all, 918 HNC survivors and 3672 matched survivors of other cancers were identified. Compared with other cancer survivors, more HNC survivors were current smokers and/or heavy drinkers (24.6% [95% CI, 21.5%-27.7%] vs 18.0% [95% CI, 16.6%-19.4%]) and exhibited a high mental health burden (18.6% [95% CI, 15.7%-21.5%] vs 13.0% [95% CI, 11.7%-14.3%]). In multivariable analyses, 1) a high mental health burden predicted for smoking and/or heavy drinking (odds ratio [OR], 1.4; 95% CI, 1.0-1.9), and 2) current cigarette smoking predicted for a high mental health burden (OR, 1.7; 95% CI, 1.2-2.3). Furthermore, nonpartnered marital status and uninsured/Medicaid insurance status were significantly associated with both cigarette smoking and/or heavy alcohol use (ORs, 1.9 [95% CI, 1.4-2.5] and 1.5 [95% CI, 1.0-2.1], respectively) and a high mental health burden (ORs, 1.4 [95% CI, 1.1 -1.8] and 3.0 [95% CI, 2.2-4.2], respectively).

CONCLUSIONS

Stakeholders should allocate greater supportive care resources to HNC survivors. The interdependence of substance abuse, adverse mental health symptoms, and other adverse patient-level influences requires development of novel, multimodal survivorship care interventions.

Diagnosis and Treatment of Alcohol-Associated Liver Disease: A Review

IMPORTANCE

Alcohol-associated liver disease results in cirrhosis in approximately 10% to 20% of patients. In 2017, more than 2 million people had alcohol-associated cirrhosis in the US. Alcohol-associated liver disease is the primary cause of liver-related mortality and the leading indication for liver transplant, representing 40% to 50% of all liver transplant in high-income countries.

OBSERVATIONS

Steatosis, alcoholic hepatitis, and fibrosis are the 3 pathologic findings that are associated with progression to cirrhosis, with highest risk in patients with alcoholic hepatitis. The amount and duration of alcohol consumption, female sex, obesity, and specific genetic polymorphisms such as patatin-like phospholipase domain protein 3, membrane bound O-acyltransferase, and transmembrane 6 superfamily member 2 genes are risk factors for alcohol-associated liver disease progression. Ten-year survival of patients with alcohol-associated liver disease is 88% among those who are abstinent and 73% for those who relapse to alcohol consumption. Symptomatic alcoholic hepatitis is characterized by rapid onset of jaundice and a 30% risk of mortality 1 year after diagnosis. Severe alcoholic hepatitis, defined as a modified discriminant function score greater than or equal to 32 or Model for End-Stage Liver Disease score (starts at 6 and capped at 40; worst = 40) greater than 20, is associated with the development of acute-on-chronic liver failure and multiorgan failure. Corticosteroid therapy is associated with improved 1-month survival from 65% in untreated patients to 80% in treated patients. Early liver transplant may be appropriate in highly select patients with severe alcoholic hepatitis who do not respond to medical therapy. In patients with decompensated cirrhosis, liver transplant should be considered if the Model for End-Stage Liver Disease score remains greater than 17 after 3 months of alcohol abstinence. Between 2014 and 2019, the proportion of patients waiting for liver transplantation who had alcohol-associated liver disease increased from 22% to 40%. Alcohol-associated cirrhosis accounted for approximately 27% of 1.32 million deaths worldwide related to cirrhosis in 2017.

CONCLUSIONS AND RELEVANCE

Alcohol-associated liver disease is among the most common liver diseases and more than 2 million people in the US in 2017 had alcohol-associated cirrhosis. Corticosteroid therapy improves survival in select patients with severe alcoholic hepatitis. Liver transplantation is the most effective therapy in patients with decompensated liver disease.

Computer-delivered personalized feedback intervention for hazardous drinkers with elevated anxiety sensitivity: A pilot randomized controlled trial

Hazardous drinkers with emotional vulnerabilities (e.g., elevated anxiety sensitivity) remain an underserved group. This study aimed to evaluate the feasibility, acceptability, and initial efficacy of a single session remotely-delivered personalized feedback intervention (PFI) targeting alcohol (mis)use and anxiety sensitivity among college students. Hazardous drinkers with elevated anxiety sensitivity (N = 125; 76.8% female; M_age = 22.14; 66.4% racial/ethnic minorities) were randomized to receive the integrated PFI (n = 63) or attention control (n = 62). Follow-up assessments were conducted one-week, one-month and three-months post-intervention. Latent growth curve modeling was used to test pilot outcomes. It was feasible to recruit and retain hazardous drinking students with elevated anxiety sensitivity through follow-up with no group differences in retention. The integrated PFI was rated as more acceptable than the control with medium/large differences (p's < 0.004; d's = 0.54-0.80). The integrated PFI group had statistically significantly greater change in primary outcomes: motivation, hazardous alcohol use, and anxiety sensitivity (p's < 0.05; d's = 0.08-0.37) with larger within-group effect sizes (d's = 0.48-0.61) than in control (d's = 0.26-0.54). Despite a small sample size, this one-session intervention offers promise among a high-risk group of drinkers with emotional vulnerabilities. The computer-based format may allow for mass distribution of a low-cost intervention in the future; however, follow-up testing in larger samples is needed.

Binge Drinking, Other Substance Use, and Concurrent Use in the U.S., 2016-2018

INTRODUCTION

The use of multiple substances heightens the risk of overdose. Multiple substances, including alcohol, are commonly found among people who experience overdose-related mortality. However, the associations between alcohol use and the use of a range of other substances are often not assessed. Therefore, this study examines the associations between drinking patterns (e.g., binge drinking) and other substance use in the U.S., the concurrent use of alcohol and prescription drug misuse, and how other substance use varies by binge-drinking frequency.

METHODS

Past 30-day alcohol and other substance use data from the 2016-2018 National Survey on Drug Use and Health were analyzed in 2020 among 169,486 U.S. respondents aged ≥12 years.

RESULTS

The prevalence of other substance use ranged from 6.0% (nondrinkers) to 24.1% (binge drinkers). Among people who used substances, 22.2% of binge drinkers reported using substances in 2 additional substance categories. Binge drinking was associated with 4.2 (95% CI=3.9, 4.4) greater adjusted odds of other substance use than nondrinking. Binge drinkers were twice as likely to report concurrent prescription drug misuse while drinking as nonbinge drinkers. The prevalence of substance use increased with binge-drinking frequency.

CONCLUSIONS

Binge drinking was associated with other substance use and concurrent prescription drug misuse while drinking. These findings can guide the implementation of a comprehensive approach to prevent binge drinking, substance misuse, and overdoses. This might include population-level strategies recommended by the Community Preventive Services Task Force to prevent binge drinking (e.g., increasing alcohol taxes and regulating alcohol outlet density).

Is a better planned day a healthier day? A daily diary study

OBJECTIVE

Previous research has shown that intentions, implementation intentions, active planning and coping planning predict engagement in important health behaviours. This study investigated the role of general daily planning as opposed to specific behaviour planning as a predictor of engagement in lifestyle behaviours. The study also examined conscientiousness and mean levels of planning as moderators of that relationship.

DESIGN

This study utilised a daily diary approach wherein 76 adults were recruited to complete daily diary surveys for 14 days. Multilevel models assessed the within- and between-person relationships between planning and five lifestyle behaviours.

MAIN OUTCOME MEASURES

Physical exercise, fruit and vegetable intake, time spent in social interaction, time spent in nature and heavy alcohol intake.

RESULTS

Within-person general daily planning predicted engagement in exercise. Interactions were found between within-person general daily planning and between-person general daily planning as predictors of exercise, social interaction and time spent in nature.

CONCLUSION

These findings introduce general daily planning as a potentially influential variable for explaining engagement in some lifestyle behaviours. Further, the interactions shed further light on when planning may be more and less helpful depending on individual differences.

Does Reducing Drinking in Patients with Unhealthy Alcohol Use Improve Pain Interference, Use of Other Substances, and Psychiatric Symptoms?

BACKGROUND

We aimed to investigate the impact of reducing drinking in patients with unhealthy alcohol use on improvement of chronic pain interference, substance use, and psychiatric symptoms.

METHODS

We analyzed longitudinal data from 2003 to 2015 in the Veterans Aging Cohort Study, a prospective, multisite observational study of US veterans, by emulating a hypothetical randomized trial (a target trial). Alcohol use was assessed using the Alcohol Use Disorders Identification Test (AUDIT) questionnaire, and outcome conditions were assessed via validated survey items. Individuals were followed from the first time their AUDIT score was ≥ 8 (baseline), a threshold consistent with unhealthy alcohol use. We compared individuals who reduced drinking (AUDIT < 8) at the next follow-up visit with individuals who did not (AUDIT ≥ 8). We fit separate logistic regression models to estimate odds ratios for improvement of each condition 2 years postbaseline among individuals who had that condition at baseline: moderate or severe pain interference symptoms, tobacco smoking, cannabis use, cocaine use, depressive symptoms, and anxiety symptoms. Inverse probability weighting was used to account for potential selection bias and confounding.

RESULTS

Adjusted 2-year odds ratios (95% confidence intervals) for associations between reducing drinking and improvement or resolution of each condition were as follows: 1.49 (0.91, 2.42) for pain interference symptoms, 1.57 (0.93, 2.63) for tobacco smoking, 1.65 (0.92, 2.95) for cannabis use, 1.83 (1.03, 3.27) for cocaine use, 1.11 (0.64, 1.92) for depressive symptoms, and 1.33 (0.80, 2.22) for anxiety symptoms.

CONCLUSIONS

We found some evidence for improvement of pain interference symptoms and substance use after reducing drinking among US veterans with unhealthy alcohol use, but confidence intervals were wide.

Insights Provided by Depression Screening Regarding Pain, Anxiety, and Substance use in a Veteran Population

Objective:

We sought to quantify the extent to which a depression screening instrument commonly used in primary care settings provides additional information regarding pain interference symptoms, anxiety, and substance use.

Methods:

Veterans Aging Cohort Study (VACS) data collected from 2003 through 2015 was used to calculate odds ratios (OR) for associations between positive depression screening result cutoffs and clustering conditions. We assessed the test performance characteristics (likelihood ratio value, positive predictive value, and the percentage of individuals correctly classified) of a positive Patient Health Questionnaire (PHQ-9 & PHQ-2) depression screen for the identification of pain interference symptoms, anxiety, and substance use.

Results:

A total 7731 participants were included in the analyses. The median age was 50 years. The PHQ-9 threshold of ≥20 was strongly associated with pain interference symptoms (OR 21.6, 95% CI 17.5-26.7) and anxiety (OR 72.1, 95% CI 52.8-99.0) and yielded likelihood ratio values of 7.5 for pain interference symptoms and 21.8 for anxiety and positive predictive values (PPV) of 84% and 95%, respectively. A PHQ-9 score of ≥10 still showed significant associations with pain interference symptoms (OR 6.1, 95% CI 5.4-6.9) and symptoms of anxiety (OR 11.3, 95% CI 9.7-13.1) and yet yielded lower likelihood ratio values (4.36 & 8.24, respectively). The PHQ-9 was less strongly associated with various forms of substance use.

Conclusion:

Depression screening provides substantial additional information regarding the likelihood of pain interference symptoms and anxiety and should trigger diagnostic assessments for these other conditions.
