Psychometric Properties of Brief Screening Tests for Alcohol Use Disorders during Pregnancy in Argentina

Does This Patient Have Alcohol Use Disorder?: The Rational Clinical Examination Systematic Review

Importance

The accuracy of screening tests for alcohol use disorder (defined as a problematic pattern of alcohol use leading to clinically significant impairment or distress) requires reassessment to align with the latest definition in the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5).

Objective

To assess the diagnostic accuracy of screening tools in identifying individuals with alcohol use disorder as defined in the DSM-5.

Data Sources and Study Selection

The databases of MEDLINE and Embase were searched (January 2013-February 2023) for original studies on the diagnostic accuracy of brief screening tools to identify alcohol use disorder according to the DSM-5 definition. Because diagnosis of alcohol use disorder does not include excessive alcohol use as a criterion, studies of screening tools that identify excessive or high-risk drinking among younger (aged 9-18 years), older (aged ≥65 years), and pregnant persons also were retained.

Data Extraction and Synthesis

Sensitivity, specificity, and likelihood ratios (LRs) were calculated. When appropriate, a meta-analysis was performed to calculate a summary LR.

Results

Of 4303 identified studies, 35 were retained (N = 79 633). There were 11 691 individuals with alcohol use disorder or a history of excessive drinking. Across all age categories, a score of 8 or greater on the Alcohol Use Disorders Identification Test (AUDIT) increased the likelihood of alcohol use disorder (LR, 6.5 [95% CI, 3.9-11]). A positive screening result using AUDIT identified alcohol use disorder better among females (LR, 6.9 [95% CI, 3.9-12]) than among males (LR, 3.8 [95% CI, 2.6-5.5]) (P = .003). An AUDIT score of less than 8 reduced the likelihood of alcohol use disorder similarly for both males and females (LR, 0.33 [95% CI, 0.20-0.52]). The abbreviated AUDIT-Consumption (AUDIT-C) has sex-specific cutoff scores of 4 or greater for males and 3 or greater for females, but was less useful for identifying alcohol use disorder (males: LR, 1.8 [95% CI, 1.5-2.2]; females: LR, 2.0 [95% CI, 1.8-2.3]). The AUDIT-C appeared useful for identifying measures of excessive alcohol use in younger people (aged 9-18 years) and in those older than 60 years of age. For those younger than 18 years of age, the National Institute on Alcohol Abuse and Alcoholism age-specific drinking thresholds were helpful for assessing the likelihood of alcohol use disorder at the lowest risk threshold (LR, 0.15 [95% CI, 0.11-0.21]), at the moderate risk threshold (LR, 3.4 [95% CI, 2.8-4.1]), and at the highest risk threshold (LR, 15 [95% CI, 12-19]). Among persons who were pregnant and screened within 48 hours after delivery, an AUDIT score of 4 or greater identified those more likely to have alcohol use disorder (LR, 6.4 [95% CI, 5.1-8.0]), whereas scores of less than 2 for the Tolerance, Worried, Eye-Opener, Amnesia and Cut-Down screening tool and the Tolerance, Annoyed, Cut-Down and Eye-Opener screening tool identified alcohol use disorder similarly (LR, 0.05 [95% CI, 0.01-0.20]).

Conclusions and Relevance

The AUDIT screening tool is useful to identify alcohol use disorder in adults and in individuals within 48 hours postpartum. The National Institute on Alcohol Abuse and Alcoholism youth screening tool is helpful to identify children and adolescents with alcohol use disorder. The AUDIT-C appears useful for identifying various measures of excessive alcohol use in young people and in older adults.

Alcohol consumption and associated factors among pregnant women attending antenatal care at governmental hospitals in Harari regional state, Eastern, Ethiopia

BACKGROUND

Alcohol consumption during the pregnancy period is high despite the well-established evidence of its harmful effects on pregnancy and infant development. Early identification and behavioral modification are of great significance. This study aimed to assess the prevalence and associated factors of alcohol consumption among pregnant women attending antenatal care at governmental hospitals in the Harari regional state, Eastern Ethiopia.

METHOD

From April 1/2022-May 1/2022, an institutional-based cross-sectional survey was conducted among 589 pregnant women attending antenatal care governmental hospitals in Harari regional state. A systematic random sampling technique was used to select study participants during the study period. Data were collected through face-to-face interview methods using AUDIT-C. The collected data were coded, entered into Epi-data data version 3.1, and analyzed by SPSS Version 26. Binary logistic regression was carried out to identify independent predictors of alcohol consumption at a 95% confidence level.

RESULTS

From a total of 617 eligible participants, 589 participated in the study with a response rate of 95.46%. The overall prevalence of alcohol consumption among pregnant women in Harari regional state governmental hospitals was 21.2% (95% CI:17.8, 24.4). In multivariate analysis, single marital status (AOR = 5.18;95% CI (2.66,10.11), previous history of abortion(AOR = 4.07;95% CI(2.06,8.04), family history of mental illness (AOR = 4.79;95% CI (1.94,11.83), depression (AOR 2.79; 95%CI(1.35,5.76), and anxiety(AOR = 2.51; 95% CI (1.23, 5.12) were variables found to have a statistically significant association with alcohol consumption during pregnancy in Harari regional state governmental hospitals.

CONCLUSION

In comparison to the majority of other research, the prevalence of alcohol usage during pregnancy was high in this study. This study observed that single marital status, previous history of abortion, family history of mental illness, depression, and anxiety were highly associated with alcohol consumption during pregnancy. Hence, responsible bodies working on mother and child health should try to mitigate or remove the above-mentioned risks when developing interventions.

Uptake of HIV Self-Testing and Associated Factors Among Female Sex Workers at Non-Governmental HIV Testing Facilities in Debre Markos and Bahir Dar Towns, Northwest Ethiopia, 2022

Background

Human immunodeficiency virus self-testing (HIVST) is universally accepted as an HIV testing option to achieve the United Nations Agency for International Development first 95 goal by 2030. HIV testing coverage through voluntary counseling and testing and provider initiated testing and counseling is low among female sex workers (FSWs). However, there is no evidence on the level of HIVST among FSWs in the study area.

Objective

To assess the uptake of HIVST and associated factors among FSWs at non-governmental facilities in Debre Markos and Bahir Dar towns, Northwest Ethiopia, 2022.

Methods

An institution-based cross-sectional study design was employed. A total of 423 study participants were selected by systematic random sampling technique. The data were collected using a structured and pre-tested questionnaire; entered into EpiData version 3.1 and exported to SPSS version 25 for analysis. An adjusted odds ratio (AOR) with a 95% confidence interval (CI) was estimated to assess the strength of association between independent variables and dependent variable. Bivariable logistic regression was done for each variable and those with a P-value of < 0.25% were selected for multivariable analysis. Finally, P-value < 0.05% was declared statistically significant.

Results

The magnitude of HIVST uptake among FSWs was 59.3%. Time since engagement of sex work > 5 years [AOR 2.16 (95% CI: 1.158-4.013)], age of first sexual debut >19 years [AOR 3.23 (95% CI: 2.045-5.093)], previous urban residence [AOR 3.99 (95% CI: 2.58-6.18)], good knowledge towards HIVST [AOR 1.78 (95% CI: 1.066-2.964)], education status being college and above [AOR 5.6 (95% CI: 3.12-9.30)] were significantly associated factors.

Conclusion

HIVST uptake among FSWs was 59.3% which is lower than expected at national level. Educational status, age at first sexual debut, knowledge towards HIVST, and time since engagement in sex work were significantly associated with HIVST uptake.

Alcohol consumption and its determinants among pregnant women in Gozamin district, Amhara, Ethiopia, 2020

Objective

Alcohol consumption during pregnancy can cause many major severe illnesses to both mothers and their offspring. Despite this, many pregnant women consume both homemade and manufactured alcoholic beverages. We conducted this study to assess the prevalence and determinants of alcohol consumption among pregnant women in Gozamin district, Amhara, Ethiopia, in 2020.

Methods

Community-based cross-sectional study was employed from 1 to 30 November, 2020. The participants were recruited using a stratified multi-stage sampling technique. A structured and pretested interviewer-administered questionnaire was utilized for data collection. The collected data were entered into Epi-data Version 3.1 and exported to SPSS Version 25 for further analysis. The model fitness was checked by Hosmer and Lemeshow's goodness of fit test. Then, logistic regression models were considered to determine the associations of independent variables with the outcome variable. Variables with p < 0.25 in bivariable logistic regression were considered for multivariable logistic regression. Finally, variables with p < 0.05 in multivariable logistic regression were considered as determinants of alcohol consumption.

Result

A total of 555 pregnant women participated in this study, making the response rate of 97.4%. The prevalence of alcohol consumption among the participants was 45.6% (95% confidence interval = 41.4-49.2). The determinants of alcohol consumption among the participants were highest wealth index (adjusted odds ratio = 3.21; 95% CI = 1.68-6.14), pre-pregnancy alcohol consumption (adjusted odds ratio = 3.67; 95% confidence interval = 2.36-5.71), poor social support (adjusted odds ratio = 3.08; 95% confidence interval = 1.60-5.94), and unplanned pregnancy (adjusted odds ratio = 1.66; 95% confidence interval = 1.04-2.66).

Conclusion

In this study, the prevalence of alcohol consumption was high among the pregnant women. Our findings suggest introduction of policies and interventions that can help reduce alcohol consumption during pregnancy. The health education priority should be creation of awareness about the negative health impacts of alcohol on the health of pregnant mothers and their offspring.

Efficacy of Brief Intervention for Alcohol Consumption during Pregnancy in Argentinean Women: A Randomized Controlled Trial

INTRODUCTION

Although Brief Intervention (BI) has proven to reduce alcohol consumption during pregnancy in high income countries, there is no evidence from the Southern Cone of America. Thus, we conducted a study to assess BI efficacy among Argentinean pregnant women.

METHOD AND MATERIALS

We collected data on pregnant women receiving prenatal care at the public health system in Mar del Plata, Argentina. Women with less than 26 weeks of gestation (n = 486) were randomized to brief advice (BA) or BI. Three months later they were re-assessed; women with more than 26 weeks of gestation constituted a screening only control group (SC) (n = 154). Self-reported quantity and frequency of alcohol consumption, frequency of binge drinking, and related problems after three months were used as outcomes. We performed generalized estimating equations and clinical significance analyses. Also, we obtained newborn health indicators from the city's health system database to use as objective outcomes. Women who did not participate in any of the three former conditions were randomly selected to constitute a non-screening control group (NSC) (n = 150). We compared objective outcomes among BI, BA, and NSC groups using the Wilcoxon rank test.

RESULTS

In comparison with SC, BI and BA reduced alcohol consumption, without differences between the latter two. Newborns of women who received BI and BA had better health indicators compared with the NSC group.

CONCLUSIONS

performing either a BI or BA reduces alcohol consumption among Argentinean pregnant women and might lead to healthier newborns.

Screening for Alcohol Use in Pregnancy: a Review of Current Practices and Perspectives

Global trends of increasing alcohol consumption among women of childbearing age, social acceptability of women's alcohol use, as well as recent changes in alcohol use patterns due to the COVID-19 pandemic may put many pregnancies at higher risk for prenatal alcohol exposure (PAE), which can cause fetal alcohol spectrum disorder (FASD). Therefore, screening of pregnant women for alcohol use has become more important than ever and should be a public health priority. This narrative review presents the state of the science on various existing prenatal alcohol use screening strategies, including the clinical utility of validated alcohol use screening instruments. It also discusses barriers for alcohol use screening in pregnancy, such as practitioner constraints, unplanned pregnancies, delayed access to prenatal care, and stigma associated with substance use in pregnancy, providing recommendations to address these barriers. By implementing consistent alcohol use screening, prenatal care providers have the opportunity to facilitate access to counseling and brief interventions and thus, to prevent new cases of FASD and improve maternal and child health.

The effects of maternal alcohol consumption during pregnancy on adverse fetal outcomes among pregnant women attending antenatal care at public health facilities in Gondar town, Northwest Ethiopia: a prospective cohort study

BACKGROUND

The teratogenic effect of fetal alcohol exposure may lead to actual and potential problems, instantly after birth, at infancy; or even later, and mental impairment in life. This study aimed to investigate the effects of maternal alcohol consumption during pregnancy on adverse fetal outcomes at Gondar town public health facilities, Northwest Ethiopia.

METHODS

A facility-based prospective cohort study was performed among 1778 pregnant women who were booked for antenatal care in selected public health facilities from 29 October 2019 to 7 May 2020 in Gondar town. We used a two-stage random sampling technique to recruit and include participants in the cohort. Data were collected using the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) standardized and pre-tested questionnaire. Multivariable analysis was performed to examine the association between reported prenatal alcohol exposure (non-hazardous and hazardous) and interested adverse birth outcomes using log-binomial regression modeling. The burden of outcomes was reported using the adjusted risk ratio and population-attributable risk (PAR).

RESULTS

A total of 1686 pregnant women were included in the analysis, which revealed that the incidences of low birth weight, preterm, and stillbirth were 12.63% (95% CI: 11.12, 14.31), 6.05% (95% CI: 5.00, 7.29) and 4.27% (95% CI: 3.4, 5.35), respectively. Non-hazardous and hazardous alcohol consumption during pregnancy was significantly associated with low birth weight (ARR = 1.50; 95% CI: 1.31, 1.98) and (ARR = 2.34; 95% CI: 1.66, 3.30), respectively. Hazardous alcohol consumption during pregnancy was also significantly associated with preterm birth (ARR = 2.06; 95% CI: 1.21, 3.52). The adjusted PAR of low birth weight related to non-hazardous and hazardous alcohol drinking during pregnancy was 11.72 and 8.44%, respectively. The adjusted PAR of hazardous alcohol consumption was 6.80% for preterm.

CONCLUSIONS

Our findings suggest that there is an increasing risk of adverse birth outcomes, particularly preterm delivery and low birth weight, with increasing levels of alcohol intake. This result showed that the prevention of maternal alcohol use during pregnancy has the potential to reduce low birth weight and preterm birth. Hence, screening women for alcohol use during antenatal care visits and providing advice with rigorous follow-up of women who used alcohol may save the fetus from the potential risks of adverse birth outcomes.

Determinants of hazardous alcohol use among pregnant women attending antenatal care at public health facilities in Gondar town, Northwest Ethiopia: A nested case-control study

BACKGROUND

Alcohol use during pregnancy has a potential negative impact on the health of women and children. Binge or hazardous drinking may do greater alcohol-related damage to the developing fetus than drinking a comparable amount spread over several days or weeks. This study aimed to identify determinants of hazardous alcohol use among pregnant women attending antenatal care at Gondar town public health facilities, Northwest Ethiopia.

METHODS

An unmatched facility-based nested case-control study was carried out to identify the determinants of hazardous alcohol use among pregnant women within a prospective cohort study from 29 October 2019 to 7 May 2020. A two-stage random sampling technique was used to select 455 (113 cases and 342 controls) pregnant women. Data collection was performed using the AUDIT-C standardized and pretested questionnaire. Bivariable and multivariable logistic regression analyses were computed to identify the predictors of alcohol consumption using the odds ratio, 95% CI, and p-value < 0.05.

RESULTS

Multivariable logistic regression model revealed that no formal education of the husbands [AOR = 2.79; 95%CI: 1.24, 6.29], being housewife[AOR = 2.43; 95%CI: 1.12, 5.26], poor household wealth index[AOR = 2.65; 95%CI: 1.07, 6.54], unplanned pregnancy [AOR = 4.36;95%CI: 2.44, 7.79], poor social support [AOR = 4.9;95%CI: 2.4, 10.04], depression[AOR = 3.84;95%CI: 2.16, 6.82], and not ever heard the risk of alcohol drinking during pregnancy [AOR = 1.97; 95%CI: 1.08, 3.58] were significantly associated with hazardous alcohol use.

CONCLUSIONS

Routine alcohol screening during ANC visits creates an appropriate referral system for clinical management and provides an opportunity for healthcare workers to offer information on the potential risks associated with alcohol use in pregnancy. Antenatal care providers have a special role to play in assuring that women receive adequate advice about alcohol use and care to manage the problems especially for pregnant women with depression, poor social support, unplanned pregnancy, low socioeconomic status, and for housewives during the antenatal visits. The warning marks on alcoholic beverages including an ongoing message about the risks of alcohol use during pregnancy could be public health good strategies to minimize preventable harms attributed to alcohol consumption during pregnancy.

Individual and community-level predictors of maternal alcohol consumption during pregnancy in Gondar town, Northwest Ethiopia: a multilevel logistic regression analysis

BACKGROUND

Prenatal alcohol consumption is a serious public health concern that is considered as one of the preventable risk factors for neonatal and childhood morbidity and several adverse pregnancy outcomes. This study aimed to determine the individual- and community-level predictors of maternal alcohol consumption during pregnancy in Gondar town, Northwest Ethiopia.

METHODS

A community-based cross-sectional study was conducted among pregnant women in Gondar town from 13 June to 24 August 2019. A cluster random sampling technique was used to select 1237 pregnant women. Data collection was carried out using the AUDIT-C pretested standard questionnaire. Bivariable and multivariable multilevel logistic regression analyses were computed to identify predictors of alcohol consumption using the odds ratio, 95% CI, and p-value < 0.05.

RESULTS

The prevalence of alcohol consumption during pregnancy was found to be 30.26% (95% CI: 27.74%, 32.91%). The study revealed that pregnant women who have a low knowledge level on harmful effect of alcohol consumption (AOR = 3.2; 95% CI: 1.9, 5.4), positive attitude towards alcohol consumption (AOR = 7.5; 95% 5, 11), history of pre-pregnancy alcohol consumption (AOR = 4.8; 95% CI: 3.4, 6.9), whose partner consume alcohol (AOR = 3.9; 95% CI: 2.5, 6), a perception that alcohol consumption is culturally or socially acceptable (AOR = 3.6; 95% CI: 2.4, 5.3), who were encouraged by their partners to consume alcohol (AOR = 4; 95% CI: 1.9, 8) were significantly associated with pregnancy alcohol consumption. Concerning the community-level characteristics, who had not ever heard/media exposure about the risk of alcohol drinking during pregnancy (AOR = 3; 95% CI: 1.7, 5.5), and who were from low community women's education attainment (AOR = 4; 95% CI: 2.2, 7.7) were statistically significant predictors of alcohol consumption during pregnancy.

CONCLUSIONS

The study revealed that alcohol consumption during pregnancy is prevalent in Gondar town. Both individual- and community-level predictors were found to be associated with alcohol consumption during pregnancy. Policymakers may take into account these predictors for individual and community-based interventions to which our results appear to point.

Neonatal near miss and the occurrence of negative outcomes in the first year of life: data from a national survey, Nascer no Brasil (Born in Brazil), 2011-2012

Abstract Objectives: estimate the strength of association between neonatal near miss and the nega-tive outcomes in the child’s first year of life. Methods: a prospective cohort study on neonatal survivors originating from a national survey “Nascer no Brasil (Born in Brazil), 2011-2012.” Main exposure: neonatal near miss (NNM). Negative outcomes: breastfeeding, hospitalization, and post neonatal death (tele-phone interview). For each outcome, the odds ratio (OR) were estimated by univariate (p<0.2) and multivariate (p<0.05) logistic regression models. Results: among 15,675 children 3.3% were neonatal near miss. Neonatal near miss was associated, after adjusting, to: weaning (OR=1.8); hospitalization after hospital discharge (OR=2.2); remained hospitalized (OR=65.6) and post neonatal death (OR=52.4) The increased OR after adjusting revealed negative confounding, such as “remained hospitalized since childbirth” (ORcrude=21.1 and ORadjusted=65.6). Conclusions: although neonatal near miss reflects a good quality of health care, avoiding neonatal death, these survivors have higher risk of negative outcomes in the first year of life.

Alcohol use and associated factors among women attending antenatal care in Southern Ethiopia: a facility based cross sectional study

Objectives

The aim of this study was to assess the prevalence and associated factors of alcohol use among women attending Antenatal Care in Gedeo zone rural health centers (Southern Ethiopia). This was a cross-sectional study conducted among randomly selected 718 pregnant women attending Antenatal Care. Alcohol Use Disorder Identification Test-C was used to assess alcohol consumption. Variables with p-values of < 0.05 in the multivariable logistic regression were considered as having a statistically significant association with alcohol use.

Results

The prevalence of alcohol use among pregnant women attending antenatal care service was 8.1% with 95% CI (6.3–10.0). Unplanned pregnancy [AOR = 2.12, 95% CI (1.20, 3.73)], abortion history [AOR = 2.40, 95% CI (1.16, 4.96)], pre pregnancy alcohol use [AOR 2.17, 95% CI (1.18, 4.00)] and mental distress [AOR = 3.50, 95% CI (1.99, 6.15)] were variables found to have a statistically significant association with alcohol use. This calls a holistic and multi modal approach for the prevention, early identification and intervention of alcohol use during pregnancy. More emphasis should also be given for pregnant women with unplanned pregnancy, history of abortion, pre pregnancy alcohol use and mental distress.

Challenges in Accurately Assessing Prenatal Alcohol Exposure in a Study of Fetal Alcohol Spectrum Disorder in a Youth Detention Center

BACKGROUND

Prenatal alcohol exposure (PAE) can result in permanent disability, including physical, neurodevelopmental, and cognitive impairments, known as fetal alcohol spectrum disorder (FASD). Individuals with FASD are more likely to engage with the law, including being placed in detention, than individuals without FASD. Young people who were sentenced to detention participated in a FASD prevalence study in Western Australia. The diagnosis of FASD requires a multidisciplinary assessment and confirmation of maternal alcohol consumption during pregnancy. Obtaining accurate assessment of PAE for young people participating in the study was challenging.

METHODS

An interview with the birth mother or other responsible adult for young people sentenced to detention in Western Australia was conducted as part of the FASD assessment. The Alcohol Use Disorders Identification Test consumption subset (AUDIT-C), other relevant questions, and documentary evidence were used to assess PAE. PAE was categorized according to the Australian Guide to the Diagnosis of FASD: no PAE reported, confirmed or confirmed high-risk, or unknown.

RESULTS

Among the 101 participants, information on PAE was unable to be obtained for 13 (13%) young people. Of the remaining 88 participants with information of PAE, 41 reported no PAE and 47 had confirmed PAE.

CONCLUSIONS

Accurately assessing prenatal alcohol consumption is challenging in any setting, but it is exceptionally challenging when assessed 13 to 17 years retrospectively as part of a FASD assessment for a young person sentenced to detention. Recording and recoding detailed qualitative responses was required to provide an accurate assessment of PAE using the AUDIT-C. Standardized recording of PAE in antenatal and birth records would facilitate later assessments for FASD and provide opportunities for advice and support for women who continue to drink during pregnancy.

Prenatal alcohol exposure prevalence as measured by direct ethanol metabolites in meconium in a Native American tribe of the southwest

BACKGROUND

Although fetal alcohol spectrum disorders represent a significant public health problem, Native Americans are underrepresented in population and targeted screening programs. Prior reports suggest that Native American tribal communities may have a higher prevalence of alcohol use during pregnancy; however, systematic examination using ethanol biomarkers is lacking.

METHODS

This study utilized data collected through the Navajo Birth Cohort Study (NBCS)-a birth cohort study of a Southwestern tribal community. Prevalence of prenatal alcohol exposure (PAE) was assessed by a battery of meconium biomarkers among 333 NBCS participants. Meconium samples were analyzed for nine individual fatty acid ethyl ester (FAEE) species, ethyl glucuronide (EtG), and ethyl sulfate (EtS) by LC-MS/MS.

RESULTS

Participants were recruited from five hospitals at the Navajo Nation located in Arizona (Chinle, Tséhootsooí, Tuba City) and New Mexico (Gallup, Shiprock). All participants identified as Native American; most reported a personal income of <$20,000 per year (71.3%), and ≤high school education (55.3%). The most prevalent biomarker was EtS (7.8%) followed by ethyl oleate (6.9%); 5.4% of the sample were positive for at least two biomarkers.

CONCLUSIONS

Results of this study on the prevalence of PAE in the Navajo Nation, obtained for the first time with an objective comprehensive panel of meconium biomarkers, indicate that the rates in the NBCS may be comparable to the general U.S. population and are in accord with recent U.S. national survey estimates. Our findings emphasize that drinking behaviors among Native American communities in the United States can vary, and generalization across all Native American populations is not warranted.

Screening and Behavioral Counseling Interventions to Reduce Unhealthy Alcohol Use in Adolescents and Adults: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Unhealthy alcohol use is common, increasing, and a leading cause of premature mortality.

OBJECTIVE

To review literature on the effectiveness and harms of screening and counseling for unhealthy alcohol use to inform the US Preventive Services Task Force.

DATA SOURCES

MEDLINE, PubMed, PsycINFO, and the Cochrane Central Register of Controlled Trials through October 12, 2017; literature surveillance through August 1, 2018.

STUDY SELECTION

Test accuracy studies and randomized clinical trials of screening and counseling to reduce unhealthy alcohol use.

DATA EXTRACTION AND SYNTHESIS

Independent critical appraisal and data abstraction by 2 reviewers. Counseling trials were pooled using random-effects meta-analyses.

MAIN OUTCOMES AND MEASURES

Sensitivity, specificity, drinks per week, exceeding recommended limits, heavy use episodes, abstinence (for pregnant women), and other health, family, social, and legal outcomes.

RESULTS

One hundred thirteen studies (N = 314 466) were included. No studies examined benefits or harms of screening programs to reduce unhealthy alcohol use. For adolescents (10 studies [n = 171 363]), 1 study (n = 225) reported a sensitivity of 0.73 (95% CI, 0.60 to 0.83) and specificity of 0.81 (95% CI, 0.74 to 0.86) using the AUDIT-C (Alcohol Use Disorders Identification Test-Consumption) to detect the full spectrum of unhealthy alcohol use. For adults (35 studies [n = 114 182]), brief screening instruments commonly reported sensitivity and specificity between 0.70 and 0.85. Two trials of the effects of interventions to reduce unhealthy alcohol use in adolescents (n = 588) found mixed results: one reported a benefit in high-risk but not moderate-risk drinkers, and the other reported a statistically significant reduction in drinking frequency for boys but not girls; neither reported health or related outcomes. Across all populations (68 studies [n = 36 528]), counseling interventions were associated with a decrease in drinks per week (weighted mean difference, -1.6 [95% CI, -2.2 to -1.0]; 32 studies [37 effects; n = 15 974]), the proportion exceeding recommended drinking limits (odds ratio [OR], 0.60 [95% CI, 0.53 to 0.67]; 15 studies [16 effects; n = 9760]), and the proportion reporting a heavy use episode (OR, 0.67 [95% CI, 0.58 to 0.77]; 12 studies [14 effects; n = 8108]), and an increase in the proportion of pregnant women reporting abstinence (OR, 2.26 [95% CI, 1.43 to 3.56]; 5 studies [n = 796]) after 6 to 12 months. Health outcomes were sparsely reported and generally did not demonstrate group differences in effect. There was no evidence that these interventions could be harmful.

CONCLUSIONS AND RELEVANCE

Among adults, screening instruments feasible for use in primary care are available that can effectively identify people with unhealthy alcohol use, and counseling interventions in those who screen positive are associated with reductions in unhealthy alcohol use. There was no evidence that these interventions have unintended harmful effects.
