JAMA Netw Open 2023; 6:e236185. [PMID: 37000449 PMCID: PMC10066463 DOI: 10.1001/jamanetworkopen.2023.6185] [Citation(s) in RCA: 46] [Impact Index Per Article: 46.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 02/17/2023] [Indexed: 04/01/2023] Open
Abstract
Importance A previous meta-analysis of the association between alcohol use and all-cause mortality found no statistically significant reductions in mortality risk at low levels of consumption compared with lifetime nondrinkers. However, the risk estimates may have been affected by the number and quality of studies then available, especially those for women and younger cohorts. Objective To investigate the association between alcohol use and all-cause mortality, and how sources of bias may change results. Data Sources A systematic search of PubMed and Web of Science was performed to identify studies published between January 1980 and July 2021. Study Selection Cohort studies were identified by systematic review to facilitate comparisons of studies with and without some degree of controls for biases affecting distinctions between abstainers and drinkers. The review identified 107 studies of alcohol use and all-cause mortality published from 1980 to July 2021. Data Extraction and Synthesis Mixed linear regression models were used to model relative risks, first pooled for all studies and then stratified by cohort median age (<56 vs ≥56 years) and sex (male vs female). Data were analyzed from September 2021 to August 2022. Main Outcomes and Measures Relative risk estimates for the association between mean daily alcohol intake and all-cause mortality. Results There were 724 risk estimates of all-cause mortality due to alcohol intake from the 107 cohort studies (4 838 825 participants and 425 564 deaths available) for the analysis. In models adjusting for potential confounding effects of sampling variation, former drinker bias, and other prespecified study-level quality criteria, the meta-analysis of all 107 included studies found no significantly reduced risk of all-cause mortality among occasional (>0 to <1.3 g of ethanol per day; relative risk [RR], 0.96; 95% CI, 0.86-1.06; P = .41) or low-volume drinkers (1.3-24.0 g per day; RR, 0.93; P = .07) compared with lifetime nondrinkers. In the fully adjusted model, there was a nonsignificantly increased risk of all-cause mortality among drinkers who drank 25 to 44 g per day (RR, 1.05; P = .28) and significantly increased risk for drinkers who drank 45 to 64 and 65 or more grams per day (RR, 1.19 and 1.35; P < .001). There were significantly larger risks of mortality among female drinkers compared with female lifetime nondrinkers (RR, 1.22; P = .03). Conclusions and Relevance In this updated systematic review and meta-analysis, daily low or moderate alcohol intake was not significantly associated with all-cause mortality risk, while increased risk was evident at higher consumption levels, starting at lower levels for women than men.

Postdetoxification Factors Predicting Alcohol-Related Emergency Room Visits 12 to 24 Months After Discharge: Results from a Prospective Study of Patients with Alcohol Dependence. Alcohol Clin Exp Res 2015; 39:1236-42. [PMID: 26033309 DOI: 10.1111/acer.12753] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2014] [Accepted: 04/14/2015] [Indexed: 11/27/2022]
Abstract
BACKGROUND Relapse is common in patients with alcohol dependence, even after detoxification. The aims of this prospective study were to investigate changes affecting patients during the first 6 months after discharge from hospitalization for detoxification and to determine the influence of these changes on the likelihood of alcohol-related emergency room (ER) visits in the following 18-month period. METHODS The study included 88 patients hospitalized for participation in a detoxification program in the addiction department of a university hospital in Rennes, France. Alcohol consumption, psychiatric symptoms, and life events were investigated by addiction specialists during hospitalization and 6 months afterward. For each patient, the number of alcohol-related ER visits in the last 6 months was prospectively recorded at the hospital 12, 18, and 24 months after hospitalization. The rate ratios of ER visits as a function of sociodemographic variables and changes observed 6 months after discharge were estimated using Poisson regression with autoregressive errors. RESULTS Nearly half of the patients (47.7%) had ER visits in the 12- to 24-month period following discharge. The likelihood of ER visits was higher for patients living with friends/parents and for those with aggravated psychiatric symptoms, negative changes in their family life, and who had a medical follow-up in the 6 months after discharge. In contrast, the likelihood of ER visits was lower for patients living with children and those with improved psychiatric morbidity. Alcohol consumption and psychiatric symptoms at baseline had no significant effect. CONCLUSIONS Monitoring changes in psychiatric symptoms and family life early after a detoxification program may help identify patients who are vulnerable to relapse in the subsequent 18-month period. Systematic screening for these changes as early as possible, in combination with appropriate treatment and the establishment of a social support system, could be fundamental in avoiding further relapses and ER visits.

Abstract
BACKGROUND AND METHODS We examined rates and predictors of mortality in individuals (47% women) who had just initiated help-seeking for their alcohol use disorders (AUDs) at the start of the study (n=628) and were followed for 16 years. RESULTS For both women and men, the observed-to-expected mortality ratio (1.4) was lower than rates found in samples of treated individuals with AUDs, suggesting that those initiating help-seeking careers have better chances of long-term survival. Of the individuals for whom cause of death was known, 68% died of alcohol-related causes. Men were more likely to die than were women. When gender was controlled, individuals who were older and unmarried and had more alcohol dependence symptoms at baseline were more likely to die over the 16-year period. When these baseline characteristics were controlled, better drinking outcomes at 1 year were associated with a lower likelihood of subsequent death. The combination of a shorter duration of inpatient/residential care and better drinking outcomes at 1 year was related to a lower probability of death, as was the combination of a longer duration of outpatient care or Alcoholics Anonymous attendance and better drinking outcomes at 1 year. CONCLUSIONS Efforts should be made to help providers identify individuals who are not responding positively to inpatient or residential treatment and intervene to motivate participation in continuing outpatient care and community 12-step self-help groups to reduce the likelihood of a chronic and fatal AUD course.

Abstract
OBJECTIVES The present study is designed to estimate the health impact of alcohol consumption in terms of the number of deaths and person-years of life lost (PYLL) in Switzerland. To that end, three hypothetical situations have been compared to the current situation used as a reference. The underlying question was: how many deaths and person-years of life lost would be avoided if all individuals were: (1) non-drinkers, (2) low drinkers only or (3) both (either abstainers or low level drinkers)? METHODS Etiological fractions of alcohol-related health consequences by age and gender were applied to the officially reported numbers of deaths to estimate the total number of deaths and PYLL. RESULTS Depending upon the hypothetical situation, the estimated number of alcohol-related deaths varied between an overall net protective and an overall net causal effect: in situation (1), there would occur 730 additional deaths in reference to the current situation (+1.2% of the total alcohol-related mortality in Switzerland), whereas in situation (2) there would be 3460 deaths less (-5.5%). Thus, the current situation in Switzerland would be preferable compared to a society, in which no one drinks alcohol. A society, however, in which every individual drinks at low levels, would be preferable to the current situation. The corresponding figures for PYLL are 23,596 vs. 29,229 (6.4% vs. 7.9% of total PYLL). CONCLUSIONS The hypothetical situation decisively impacts on the number of deaths attributable to alcohol. In contrast, it has much less influence on the number of alcohol-related PYLL. Thus, mortality is at least a questionable indicator of alcohol-related health outcomes. The study also indicated that more lives and PYLL were saved in the low-risk situation than in the abstinence situation. Public health policies should not concentrate on the promotion of abstinence.

Abstract
BACKGROUND The objective of this study is to weigh the risks of moderate alcohol consumption against its benefits and, as a result, to derive tolerable upper alcohol intake levels (TUALs) for the German adult population. METHODS Human studies assessing the effects of moderate alcohol consumption (< or = 40 g/day) on coronary heart disease, stroke, blood pressure, diseases of the liver, gallbladder, bile duct, and pancreas, cancer of the mouth/pharynx/larynx/oesophagus, stomach, colon/rectum, and breast, foetal alcohol syndrome/foetal alcohol effects, as well as all-cause mortality, published in the 10-15 years before 1999, have been systematically reviewed. The quality of studies has been evaluated using a self-constructed evaluation scheme. As a result of comparing the critical endpoints of alcohol intake related to morbidity and mortality, the TUALs have been derived. RESULTS The TUALs have been set at 10-12 g/day for healthy women and 20-24 g/day for healthy men of the adult population (18 years and older). Additional guidelines on alcohol use have been defined, taking into account further important aspects like alcohol consumption patterns and high-risk groups. CONCLUSIONS The TUALs are not intended to be recommended intake levels. However, if the TUALs and the additional guidelines are followed, a relation of alcohol consumption to an increased risk of alcohol-associated diseases is unlikely for the majority of the population.

Abstract
Impaired health caused by alcohol abuse has been known throughout recorded history. Over the past century, alcohol abuse has been clearly linked to host susceptibility to infectious disease, particularly bacterial pneumonia. Recently, both acute and chronic alcohol intake have been shown to result in specific defects in innate and adaptive immunity; these could, in principle, be subjected to specific modulation to overcome the immunosuppressive effects of the most commonly abused substance in the Western world.

Abstract
OBJECTIVES To elaborate a state-of-the-art list of alcohol-related fatal medical conditions for future social-cost studies in Western societies. METHODS Three major social-cost studies were compared with regard to their respective section on fatal health effects attributable to long-term as well as short-term use of alcohol. On discordant conditions, a systematic literature search was conducted in the Medline and ETOH databases. RESULTS There is no consensus between social-cost studies with respect to alcohol-related causes of mortality. Based on the recent epidemiological evidence on alcohol and health, this paper suggests an up-to-date list of fatal medical conditions for which the causal relationship has been established with sufficient scientific evidence. A further investigation is needed, however, to reestimate relative risks by meta-analysis. CONCLUSIONS Evaluating new epidemiological evidence regularly is necessary for the purpose of up-to-date social-cost studies.

Abstract
Alcohol-dependent populations have a high lifetime suicide rate (between 7 and 15%, relative risk = 7), and alcoholism is one of the two psychiatric disorders most frequently found in suicidal cases (between 15 and 25%). Biological factors that would detect patients at risk could thus be of value. Carbohydrate-deficient transferrin, monoamine oxidase B, soluble interleukin-2 receptor and cholesterol have been proposed as markers of suicidal risk in alcohol-dependent patients, although nonspecific and with low predictive value. On the other hand, there is large and convergent data stressing the importance of serotonin dysregulation as increasing the risk for aggressive behaviour toward the self, although it is not clear whether serotonin is involved through the altered behavior inhibition system, enhancement of anxiety and depression, or association with specific subtypes of alcohol-dependence, such as early-onset type II alcoholism. Considering the complex but significant impact of alcohol on serotonin metabolism and turnover, it is likely that serotonin mediates a large part of the proneness of ethanol to commit impulsive-aggressive behavior.

Abstract
BACKGROUND The potential of dietary habits to confound the association between alcohol consumption and health needs further study. OBJECTIVE We examined whether eating habits differed according to alcohol consumption in a large cohort of French women. DESIGN This was a cross-sectional study of the French cohort of the European Prospective Investigation into Cancer and Nutrition (E3N-EPIC). The cohort was established in 1990 and includes 100000 women born between 1925 and 1950. Dietary data were obtained between 1993 and 1995 by using self-administered food-frequency questionnaires. About 73000 questionnaires were analyzed, and women were placed into 7 categories of alcohol consumption. RESULTS After adjustment for energy derived from alcohol, increasing alcohol consumption was associated with a higher total energy intake, a higher percentage of energy intake as protein and lipids, and higher intakes of cholesterol, fatty acids, retinol, iron, and vitamin E. Conversely, energy provided by carbohydrates decreased with increasing alcohol consumption, as did beta-carotene intake. Increasing alcohol consumption was associated with higher consumption of animal products, cheese, potatoes, oil, bread, and breakfast cereals and with lower consumption of vegetables and dairy products. CONCLUSION In this population of middle-aged, highly educated French women, marked differences in dietary patterns and nutrient intakes were found according to alcohol consumption. Part of the detrimental effect of alcohol on health may be due to the less healthy dietary habits of drinkers. This points to a confounding role of eating habits and nutrient intakes in the relation between alcohol and health.

Abstract
Over the past decade, we have observed a disparity between alcohol consumption and related mortality, especially in its regional distribution. Two epidemiological surveys carried out by CRSSA and INSERM (unit 472) focused on drinking behaviour patterns among young conscripts and secondary school students. Regular drinkers in particular were studied. Geographical distribution of regular alcohol use differs from that of alcohol-related deaths. Alcohol consumption is higher in the south of France than in the north, while mortality from alcohol abuse remains higher in the north.

Abstract
PURPOSE In France the low rates of death due to ischemic heart disease have been attributed to the high consumption of alcohol. However, the question remains: are the higher death rates for causes associated with alcohol consumption an explanation? METHODS Diseases were defined according to the International Classification of Diseases, revision 9. World Health Organization data on country- and age-specific death rates were used. RESULTS Official causes-of-death statistics for men 40-74 years of age show that in 1990 French men under 50 years old had low death rates from ischemic heart disease but a relatively high all-cause mortality rate, in contrast to low rates for men 60 to 74 years of age. Among French men aged 40-44 years in 1960, 34% had died before reaching the age of 70-74 years. In comparison, 37% in the United States and 36% in England and Wales, had died by this age, with 4.5%, 14.1%, and 15.2% of deaths, respectively, due to ischemic heart disease. If all of the men who died early of causes associated with alcohol had died of ischemic heart disease, there would still be a lower rate in France (21%) than in the United States (26%) or in England and Wales (25%). CONCLUSION Thus, although some of the chronic heavy drinkers in France die early of causes associated with excessive alcohol consumption, this is not the only reason for the low ischemic heart disease death rates.

Abstract
Epidemiological studies of the relationships between pulmonary function and reported alcohol intake showed inconsistent results. The use of biological markers of alcohol is needed. The objective of this study was to assess the relationships of alcohol consumption, assessed by a standardized questionnaire, and gamma-glutamyl transpeptidase (GGT), to forced expiratory volume in 1 sec (FEV1) level and decline over 10 years, in working men. Three hundred twenty-eight policemen aged 22-55 years were examined in 1980 (first survey) and again in 1990 (second survey). The two cross-sectional analyses used the 1980 data and the 1990 data separately. Longitudinal analysis used 1980 alcohol consumption and GGT values, and 10-year FEV1 decline. In both cross-sectional surveys, elevated alcohol consumption was significantly associated with impaired age-adjusted and height-adjusted FEV1. Further adjustment for smoking habit, education level, and asthmatic status did not alter these results. An increase of 25 g/day of alcohol was associated with 50.0 ml (95% confidence interval: 1.5 to 98.5) and 55.3 ml (95% confidence interval: 7.8 to 102.8) decrease of corresponding multivariate-adjusted FEV1 in 1980 and in 1990, respectively. GGT was also negatively associated with FEV1 in both cross-sectional surveys. Similar patterns of associations were also observed between vital capacity measurements and alcohol variables. In the longitudinal analysis, there was no relationship between either alcohol consumption or GGT and FEV1 decline. Findings suggest that alcohol consumption was associated with impaired lung function, but there was no evidence of accelerated FEV1 decline over 10 years related to alcohol consumption in this "healthy" population of middle-aged men.
