Abstract
Different studies have shown that females develop liver diseases at lower levels of alcohol consumption than males. Our aim was to quantify the dose-response relationship between alcohol consumption and the risk of liver cirrhosis by sex and identify the differences between females and males. A systematic review was conducted using PubMed/Medline and Embase to identify longitudinal and case-control studies that analyzed the relationship between the level of alcohol use and liver cirrhosis (LC) incidence, and mortality (ICD-8 and ICD-9 codes 571 and ICD-10 codes K70, K73, K74). Pooled relative risks (RR) were calculated by random effects models. Restricted cubic splines were used to model the dose-response relationship. A total of 24 studies were included in the analysis. There were collectively 2,112,476 females and 924,853 males, and a total of 4,301 and 4,231 cases of LC for females and males, respectively. We identified a non-linear dose-response relationship. Females showed a higher risk for LC compared to males with the same amount of alcohol consumed daily. For instance, drinking 40 g/day showed RRs of 9.35 (95% CI 7.64-11.45) in females and 2.82 (95% CI 2.53-3.14) in males, while drinking 80 g/day presented RRs of 23.32 (95% CI 18.24-29.82) in females and 7.93 (95% CI 7.12-8.83) in males. Additional analyses showed that a higher risk for females was found for morbidity and for mortality. Understanding the influence of sex on the association of alcohol consumption and the risk of LC is needed to develop recommendations and clinical guidelines for prevention and treatment.

Abstract
Reviewing 59 studies of the risk curve for alcohol consumption level and all-cause mortality, a general J-shaped curve is confirmed, particularly in cohorts with experience starting at middle age (rather than in youth or old age). The divergence in most studies that are exceptions to this rule can be plausibly explained. A pooled analysis of studies with cohorts age 45 and above at entry shows the most beneficial effect for women in a drinking category with a midpoint of one drink every second day, and for men in the drinking category with a midpoint of one and a half drinks per day though most of the benefit can be obtained by men, too, in the category with a midpoint of one-half drink per day. For men under 45, there was an almost linear increase in mortality risk with increasing consumption; data are lacking for a similar analysis for women. Directions are suggested for development in future studies, including the use of data on patterns of drinking.

Abstract
INTRODUCTION AND AIMS Alcohol is an established risk factor for liver cirrhosis. It remains unclear, however, whether this relationship follows a continuous dose-response pattern or has a threshold. Also, the influences of sex and end-point (i.e. mortality vs. morbidity) on the association are not known. To address these questions and to provide a quantitative assessment of the association between alcohol intake and risk of liver cirrhosis, we conducted a systematic review and meta-analysis of cohort and case-control studies. DESIGN AND METHODS Studies were identified by a literature search of Ovid MEDLINE, EMBASE, Web of Science, CINAHL, PsychINFO, ETOH and Google Scholar from January 1980 to January 2008 and by searching the references of retrieved articles. Studies were included if quantifiable information on risk and related confidence intervals with respect to at least three different levels of average alcohol intake were reported. Both categorical and continuous meta-analytic techniques were used to model the dose-response relationship. RESULTS Seventeen studies met the inclusion criteria. We found some indications for threshold effects. Alcohol consumption had a significantly larger impact on mortality of liver cirrhosis compared with morbidity. Also, the same amount of average consumption was related to a higher risk of liver cirrhosis in women than in men. DISCUSSION AND CONCLUSIONS Overall, end-point was an important source of heterogeneity among study results. This result has important implications not only for studies in which the burden of disease attributable to alcohol consumption is estimated, but also for prevention.

Abstract
This paper reviews the epidemiological evidence on the association of alcohol consumption with the major cardiovascular diseases (hypertension, stroke and coronary heart disease), and all causes of death. The focus is on light and moderate consumption and several important methodological issues are apparent with the epidemiological evidence on alcohol and mortality. The epidemiological data justify the following recommendations on alcohol consumption. The evidence does not support the unqualified claim that light and moderate drinking confers overall health benefits. However, in persons over 35 years of age, there is no consistent evidence that daily consumption of up to 2-3 drinks in men or up to 1-2 drinks in women increases the risk of dying. Non-drinkers should not be encouraged to change their drinking status. The consumption of more than 2-3 drinks per day in men and more than 1-2 drinks per day in women should be actively discouraged. Further research on the effects of light and moderate alcohol consumption on cardiovascular disease and all causes of death are required, particularly in young people, women and the elderly.

Abstract
Studies evaluating the health benefits of alcohol and wine have demonstrated that moderate consumption is associated with a decrease in all-cause and cardiovascular mortality. Various populations and alcoholic beverages exhibit this effect to different degrees. Alcoholic beverages exhibit multiple mechanisms that may favorably influence cardiac risk potential actions on platelets, antioxidants, fibrinolysis, and lipids. However, other data suggest that the perceived benefit of alcoholic beverages in general, and wine in particular, are the result of socioeconomic confounders. In the absence of more rigorous evidence, it is not currently possible to define the role of wine in human health.

Abstract
BACKGROUND/OBJECTIVE Moderate alcohol consumption has beneficial effects on survival. Sex differences, however, have been suggested implying less beneficial effect among women. We examined the impact of alcohol consumed on weekdays and at weekends, respectively, on risk of death among women. SUBJECTS AND METHODS At baseline in 1993, a total of 17 772 female members of the Danish Nurse Association completed questionnaires on alcohol intake and other lifestyle factors. The influence of alcohol intake on risk of death was analyzed using Cox proportional hazard model. RESULTS Alcohol intake of 1-3 drinks per week was associated with the lowest risk of death. Intake above six drinks per weekend (Friday through Sunday) increased risk of death from all causes by 3% for each additional drink consumed per weekend (corresponding to an increased risk by 9% per drink per weekend day). Consumption of one or more drinks per weekday (Monday, Tuesday, Wednesday or Thursday) increased risk by 4% for each additional drink consumed per day. CONCLUSIONS The results indicated an increasing risk of death for intake above six drinks per weekend and of one or more drinks per weekday.

Abstract
PURPOSE OF REVIEW Light-to-moderate alcohol intake is known to have cardioprotective properties in some subsets of the population. This review focuses on factors that modify the relation between alcohol and cardiovascular disease. RECENT FINDINGS Several large American studies have shown that the J-shaped relation is influenced by age and coronary heart disease risk-factor status since only middle-aged and elderly and those already at risk of developing coronary heart disease seem protected by drinking alcohol. It has also been suggested that only those who have a steady - in contrast to a binge - intake of alcohol have benefits with regard to cardiovascular disease. Prospective studies from the UK, Sweden and Denmark have further suggested that wine drinkers have a lower mortality than beer and spirits drinkers. SUMMARY The J-shaped relation between alcohol intake and cardiovascular disease seems to be influenced by age, gender, drinking pattern and type of alcohol.

Abstract
OBJECTIVE To evaluate the effect of alcohol on coronary heart disease (CHD), cancer incidence, and cancer mortality by smoking history. DESIGN/SETTING A prospective, general community cohort was established with a baseline mailed questionnaire completed in 1986. PARTICIPANTS A population-based sample of 41,836 Iowa women aged 55-69 years. MEASUREMENTS Mortality (total, cancer, and CHD) and cancer incidence outcomes were collected through 1999. Relative hazard rates (HR) were calculated using Cox regression analyses. MAIN RESULTS Among never smokers, alcohol consumption (> or =14 g/day vs none) was inversely associated with age-adjusted CHD mortality (HR, 0.40; 95% confidence interval [CI], 0.19 to 0.84) and total mortality (HR, 0.71; 95% CI, 0.55 to 0.92). Among former smokers, alcohol consumption was also inversely associated with CHD mortality (HR, 0.45; 95% CI, 0.23 to 0.88) and total mortality (HR, 0.78; 95% CI, 0.62 to 0.97), but was positively associated with cancer incidence (HR, 1.25; 95% CI, 1.03 to 1.51). Among current smokers, alcohol consumption was not associated with CHD mortality (HR, 1.05; 95% CI, 0.73 to 1.50) or total mortality (HR, 1.07; 95% CI, 0.92 to 1.25), but was positively associated with cancer incidence (HR, 1.30; 95% CI, 1.10 to 1.54). CONCLUSIONS Health behavior counseling regarding alcohol consumption for cardioprotection should include a discussion of the lack of a decreased risk of CHD mortality for current smokers and the increased cancer risk among former and current smokers.

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
The impact of alcohol intake on mortality from all causes has been described in a large number of prospective population studies from many countries. Most have shown a J-shaped relation between alcohol intake and subsequent mortality, indicating that there are both beneficial and harmful effects of ethanol on health. The risk of death from ischemic heart disease is seen to be significantly increased, and highest among abstainers, but not significantly increased among heavy drinkers. Some studies have found plausible mechanisms for the beneficial effect of light to moderate drinking. Subjects with a moderate alcohol intake have a higher level of high density lipoprotein than abstainers. Further, moderate drinkers are seen to have a lower low density lipoprotein. Also, alcohol has a beneficial effect on platelet aggregation, and thrombin level in blood is higher among drinkers than among non-drinkers. In the other end of the range of intake, the ascending leg of the U-shaped curve has been explained by the increased risk of cirrhosis, pancreatitis, and development oropharynx, oesophagus, and breast cancer. In exploring the French paradox, it has been suggested that wine may have beneficial effects additional to that of ethanol. Recently, several prospective population studies have supported this idea. It is, however, also likely that the apparent additional beneficial effect of wine on health in addition to the effect of ethanol itself is a consequence of confounding.

Abstract
BACKGROUND: We examined the association between alcohol consumption and all-cause mortality in Japanese men and women. METHODS: From June through August 1990, a total of 39,076 subjects (20,660 men and 18,416 women) in 14 municipalities of Miyagi Prefecture in rural northern Japan (40-64 years of age) completed a self-administered questionnaire that included information about alcohol consumption and various health habits. During 11 years of follow-up, we identified 1,879 deaths (1,335 men and 544 women). We used Cox proportional-hazards regression to estimate relative risk (RR) of all-cause mortality according to categories of alcohol consumption and to adjust for age, education, marital status, past histories of chronic diseases, body mass index, smoking, walking and dietary variables. RESULTS: Among men, the risk for all-cause mortality was significantly higher in past drinkers than never-drinkers (multivariate RR, 1.86; 95% confidence interval [CI], 1.50-2.29). There was a dose-response association between alcohol consumption and the risk of all-cause mortality among current drinking men: multivariate RRs in reference to never-drinkers (95% CI) were 1.10 (0.90-1.33), 1.17 (0.96-1.42), 1.16 (0.96-1.40), and 1.62 (1.32-1.99) in current drinkers who consumed less than 22.8 g, 22.8-45.5 g, 45.6-68.3 g, and 68.4 g or more alcohol per day, respectively (P for trend<0.001). Similar association was observed among women (P for trend=0.005). CONCLUSIONS: The results indicated that alcohol consumption tended to be associated with linear increase in risk of all-cause mortality among Japanese men and women, and the association was remarkable for younger men.

Abstract
CONTEXT Observational studies suggest that heavy alcohol consumption may increase the risk of stroke while moderate consumption may decrease the risk. OBJECTIVE To examine the association between alcohol consumption and relative risk of stroke. DATA SOURCES Studies published in English-language journals were retrieved by searching MEDLINE (1966-April 2002) using Medical Subject Headings alcohol drinking, ethanol, cerebrovascular accident, cerebrovascular disorders, and intracranial embolism and thrombosis and the key word stroke; Dissertation Abstracts Online using the keywords stroke and alcohol; and bibliographies of retrieved articles. STUDY SELECTION From 122 relevant retrieved reports, 35 observational studies (cohort or case control) in which total stroke, ischemic stroke, or hemorrhagic (intracerebral or total) stroke was an end point; the relative risk or relative odds and their variance (or data to calculate them) of stroke associated with alcohol consumption were reported; alcohol consumption was quantified; and abstainers served as the reference group. DATA EXTRACTION Information on study design, participant characteristics, level of alcohol consumption, stroke outcome, control for potential confounding factors, and risk estimates was abstracted independently by 3 investigators using a standardized protocol. DATA SYNTHESIS A random-effects model and meta-regression analysis were used to pool data from individual studies. Compared with abstainers, consumption of more than 60 g of alcohol per day was associated with an increased relative risk of total stroke, 1.64 (95% confidence interval [CI], 1.39-1.93); ischemic stroke, 1.69 (95% CI, 1.34-2.15); and hemorrhagic stroke, 2.18 (95% CI, 1.48-3.20), while consumption of less than 12 g/d was associated with a reduced relative risk of total stroke, 0.83 (95%, CI, 0.75-0.91) and ischemic stroke, 0.80 (95% CI, 0.67-0.96), and consumption of 12 to 24 g/d was associated with a reduced relative risk of ischemic stroke, 0.72 (95%, CI, 0.57-0.91). The meta-regression analysis revealed a significant nonlinear relationship between alcohol consumption and total and ischemic stroke and a linear relationship between alcohol consumption and hemorrhagic stroke. CONCLUSIONS These results indicate that heavy alcohol consumption increases the relative risk of stroke while light or moderate alcohol consumption may be protective against total and ischemic stroke.

Abstract
OBJECTIVE The aim of this article was to describe death rates and years of life lost prematurely (YLLP) in relation to alcohol consumption in the Canary Islands. The study covered the period between 1980 and 1998. METHODS Deaths from 1980 to 1998 were classified by age, sex, and cause using data obtained from the National Institute of Statistics (Natural Changes in the Population). The number of alcohol-related deaths was calculated by year, sex, and age group using the attributable population fraction as proposed by the Centers for Disease Control (USA). The YLLP attributed to alcohol consumption were calculated for each cause of death by multiplying deaths by the attributable population fraction in 5-yearly age groups for both sexes (average span of five years), up to the age of 65 years. RESULTS Between 1980 and 1998, the number of alcohol-related deaths was 12,614, averaging 6.4% per year and with a male-to-female ratio of approximately 2:1. The main causes of death and YLLP in both men and women were malignant neoplasms, diseases of the digestive system, and alcohol-related accidents, although accidents were by far the main cause producing 50.6% of alcohol-related YLLP in men and 55.5% in women. Over the study period, the incidence of cirrhosis of the liver and that of other chronic liver diseases (CIE 571) decreased in men whilst remaining stable in women. CONCLUSIONS The finding that the percentage of alcohol-related deaths and cirrhosis of the liver remained high in the Islas Canarias between 1980 and 1998 highlights the need for educational strategies on the effects of alcohol, together with policies designed to reduce its consumption, particularly among the young.

Abstract
The impact of alcohol intake on mortality has been described in a large number of prospective population studies from many countries. Most have shown a J-shaped relation between alcohol intake and subsequent mortality, indicating that there are both beneficial and harmful effects of ethanol on health. In exploring the French paradox, it has been suggested that wine may have beneficial effects additional to that of ethanol. Recently, several prospective population studies have supported this idea. However, it is also likely that the apparent additional beneficial effect of wine on health is confounding.

Abstract
The objective of this study was to investigate the determinants of abstinence and drinking patterns among 14,367 Greeks. Participants older than 60, single and widowed men, as well as participants living outside the Greater Athens area were significantly more likely to abstain than to be "light to moderate" drinkers. In contrast, those at higher educational levels and those separated or divorced were less likely to abstain than their counterparts. With respect to excessive drinking, older people and those at higher educational levels were less likely to engage excessive drinking than their counterparts. Among men, subjects who were separated or divorced were more likely to drink excessively than those who were married. The results of our study help detect groups at high risk for diseases associated with high or low consumption of alcohol, and outline preventive strategies.

Abstract
A large body of scientific evidence associates the moderate intake of alcohol with reduced mortality among middle-aged and older people in industrialized societies. This association is due largely to a reduced risk of death from coronary heart disease, which appears to outweigh any possible adverse effects of moderate drinking. The regular consumption of small amounts of alcohol is more healthful than the sporadic consumption of larger amounts. No beneficial effect of moderate drinking on mortality has been demonstrated in young adults (premenopausal women and men who have not reached their forties). It is theoretically possible that moderate drinking in young adulthood might reduce the risk of later heart disease; however, this has not been clearly demonstrated. For some individuals (e.g., those who cannot keep their drinking moderate, pregnant women, and those who are taking medications that may interact adversely with alcoholic beverages), the risks of alcohol consumption, even in moderation, outweigh any potential benefits. Because even small amounts of alcohol can impair judgment and coordination, no one should drink alcoholic beverages, even in moderation, before driving a motor vehicle or performing other activities that involve attention and skill.

Abstract
BACKGROUND Although heavy alcohol consumption increases total mortality, light to moderate consumption decreases cardiovascular and all-cause mortality in apparently healthy people. Since data are sparse on the relation of light to moderate alcohol intake to mortality in patients with previous myocardial infarction, we did a prospective study of mortality in men. METHOD Of 90,150 men in the Physicians' Health Study enrollment cohort who provided information on alcohol intake and who had no history of cancer, stroke, or liver disease, 5358 had a previous myocardial infarction. We estimated alcohol consumption by food-frequency questionnaire. FINDINGS During a mean follow-up of 5 years, 920 men died. After adjustment for several potential confounders, moderate alcohol intake was associated with a significant decrease in total mortality (p=0.016). Compared with men who rarely or never drank alcohol, those who drank one to four drinks per month had a relative risk for total mortality of 0.85 (95% CI 0.69-1.05); for two to four drinks per week, the relative risk was 0.72 (0.58-0.89); for one drink per day 0.79 (0.64-9.96); and for two or more drinks per day 0.84 (0.55-1.26). INTERPRETATION Men with previous myocardial infarction who consume small to moderate amounts of alcohol have a lower total mortality.

Abstract
BACKGROUND Alcohol consumption has both adverse and beneficial effects on survival. We examined the balance of these in a large prospective study of mortality among U.S. adults. METHODS Of 490,000 men and women (mean age, 56 years; range, 30 to 104) who reported their alcohol and tobacco use in 1982, 46,000 died during nine years of follow-up. We compared cause-specific and rates of death from all causes across categories of base-line alcohol consumption, adjusting for other risk factors, and related drinking and smoking habits to the cumulative probability of dying between the ages of 35 and 69 years. RESULTS Causes of death associated with drinking were cirrhosis and alcoholism; cancers of the mouth, esophagus, pharynx, larynx, and liver combined; breast cancer in women; and injuries and other external causes in men. The mortality from breast cancer was 30 percent higher among women reporting at least one drink daily than among nondrinkers (relative risk, 1.3; 95 percent confidence interval, 1.1 to 1.6). The rates of death from all cardiovascular diseases were 30 to 40 percent lower among men (relative risk, 0.7; 95 percent confidence interval, 0.7 to 0.8) and women (relative risk, 0.6; 95 percent confidence interval, 0.6 to 0.7) reporting at least one drink daily than among nondrinkers, with little relation to the level of consumption. The overall death rates were lowest among men and women reporting about one drink daily. Mortality from all causes increased with heavier drinking, particularly among adults under age 60 with lower risk of cardiovascular disease. Alcohol consumption was associated with a small reduction in the overall risk of death in middle age (ages 35 to 69), whereas smoking approximately doubled this risk. CONCLUSIONS In this middle-aged and elderly population, moderate alcohol consumption slightly reduced overall mortality. The benefit depended in part on age and background cardiovascular risk and was far smaller than the large increase in risk produced by tobacco.

Abstract
This study examines the magnitude of alcohol-related premature death in the French population, which still has the highest average alcohol intake in the world and a relatively low coronary heart disease mortality rate. Two data sources were used: the national mortality data in 1990 and a prospective mortality experience in a cohort of 2,687 middle-aged working men examined in 1980-1985 and followed-up during an average of 9.3 years. In the general population study, alcohol-related premature mortality (35-64 years) was calculated using alcohol-attributable fractions (AAFs) derived from studies of alcohol involvement in deaths from various causes. In the cohort, it was estimated from AAFs and attributable risk using both alcohol exposure prevalence and relative risks of death according to alcohol intake categories. In 1990, estimates of 19.1% and 13.0% of all premature deaths in French men and women were attributed to alcohol. Digestive diseases followed by malignant neoplasms in men and by unintentional injuries in women were major contributors to the total number of alcohol-related premature deaths. In the cohort study, 90 deaths occurred during the follow-up period. The estimation of alcohol-related premature mortality using AAFs was 24.4%. The relative risk of total mortality (adjusted for age, smoking habits, and body mass index) for men who consumed > 60 ml/day of alcohol, compared with those who consumed 0-25 ml/day was 1.9 (95% confidence interval: 1.1-3.5). The consumption of 26-60 ml/day was not associated with reduced risk of mortality, and the adjusted relative risk for this group was 1.3 (95% confidence interval: 0.7-2.5). The estimated attributable risk of premature mortality caused by consumption of > 25 ml/day of alcohol was 29.9%. This study reports the persisting high alcohol-related premature mortality in the French general population, as well as in middle-aged working men. The results suggest that efforts should be paid to reduce further the consumption of alcohol in France.

Abstract
This study examined mortality risk for individuals in four alcohol consumption categories and identified life context and coping factors that independently predicted mortality among late-middle-aged drinkers and former drinkers (n = 1869). Compared with light drinkers, former drinkers (current abstainers) were at increased mortality risk; moderate drinkers were at decreased risk. Consistent with previous research on older samples, heavy drinkers were not at increased risk. Abstainers' increased risk was reduced in a model that controlled for life context and coping factors. Other independent predictors of mortality included reporting an illness stressor, stressor severity, less participation in activities with friends, greater use of resigned acceptance and alternative rewards coping, and less use of cognitive avoidance and emotional discharge coping. The findings support previous research on the alcohol-mortality relationship among older adults, and highlight the fact that abstainers' life stressors and avoidance coping responses may be more important predictors of their mortality than their abstention.

Abstract
Epidemiologic evidence suggests that alcohol consumption has distinctive associations with risk of ischemic and hemorrhagic strokes; these differences help explain apparent inconsistencies in the alcohol-stroke literature (Camargo CA Jr. Stroke 1989;20:1611-1626). To better define the impact of "moderate drinking" per se (i.e. usual consumption of < or = 2 drinks daily for men, and < or = 1 drink daily for women), the present author reviewed 26 case-control and cohort studies on this subject. There is substantial evidence that moderate drinking does not increase risk of ischemic stroke; studies remain divided, however, on the question of a "protective" association. Furthermore, although the evidence is not unanimous, two major cohort studies have found that even moderate drinking may increase risk of hemorrhagic stroke. Because ischemic strokes are 3-4 times more common than hemorrhagic strokes, the net impact of moderate drinking on stroke risk depends greatly on the relation between moderate drinking and ischemic stroke. It is most likely, however, that moderate drinking does not increase risk of all strokes combined.

Abstract
This paper addresses some issues related to the hypothesis that the risk for premature death is a J-shaped function of alcohol intake. The first part of the paper contains a discussion of the individual level epidemiological evidence. It is argued that the evidence is not yet good enough to allow precise statements about "safe limits", nor does it allow a precise location of the "optimum" consumption level. Measurement errors and confounding variables not yet controlled for remain substantial problems. In particular, future studies need to control for social integration, as this factor may affect both health status and alcohol consumption. The second part of the paper discusses the population level relationship. It is argued that, typically, what is optimum for an individual is too much for a population. Unintended side effects of major public health importance should be expected in this area. In the last section, a plea is made for aggregate level studies as a way of addressing the public health side of the issue.

Abstract
OBJECTIVE To compare the National Health and Medical Research Council (NHMRC) recommendations on responsible, hazardous and harmful alcohol intake with their effects on all-cause mortality in men and women and on the occurrence of 10 specific neoplastic, cardiovascular and alimentary diseases. DESIGN Meta-analyses of relative risks of mortality in relation to usual level of alcohol intake pooled from 16 cohort studies (mostly of adults over 35 years), and alcohol and selected conditions from a further 132 epidemiological studies. Results reported by authors were assigned to sex-specific exposure categories defined by the NHMRC based on median alcohol intakes. Pooled estimates of relative risk were calculated using precision-based weighting. SETTING The assessment was part of comprehensive meta-analysis of epidemiological research undertaken for the National Drug Strategy. RESULTS Relative risk of all-cause mortality in male drinkers compared with abstainers fell to 0.84 at 1.0-1.9 standard drinks per day, returned to 1.01 by 3.0-3.9 drinks, and increased to 1.37 at six or more drinks. In female drinkers the lowest relative risk (of 0.88) was at 0-0.9 drinks per day, and by 2.0-2.9 drinks the risk exceeded that in abstainers by 1.13; at six drinks the relative risk was 1.58. Based on NHMRC categories, the relative risks of mortality were 0.93 (0.93-0.94) in responsible drinkers, 1.24 (1.22-1.27) in hazardous drinkers and 1.37 (1.35-1.49) in harmful drinkers. Risk of cancers of the oropharynx, oesophagus, liver, larynx and female breast and of cirrhosis of the liver increased with increasing alcohol intake level. CONCLUSIONS A pattern of usual alcohol intake consistent with the NHMRC recommendations will confer a mortality risk similar to or less than that observed in abstainers. The biologically effective dose of alcohol on mortality in women is approximately two standard drinks per day less than in men. Our validation is most reliable for drinkers aged 35 years or older.

Abstract
This paper reviews epidemiological investigations which have identified an inverse relationship between alcohol consumption and death from coronary heart disease: evidence from studies of mixed populations as well as of single-sex populations have, on the whole, demonstrated that this relationship is independent of sex or age. This 'cardioprotective effect' of alcohol can be explained, at least in part, by ethanol-related increases in high density lipoprotein cholesterol and reduced platelet coagulability. With certain beverages, especially red wine, phenolic compounds may provide additional protection by altering eicosanoid metabolism in favour of increased prostacyclin and decreased thromboxane synthesis, as well as antioxidant functions which prevent the peroxidation of low-density lipoprotein. Trans-resveratrol, a tri-hydroxy stilbene present in the skins of specific grape cultivars, is a constituent of certain red wines which may play a crucial role in modulating lipoprotein metabolism, eicosanoid synthesis, oxidation and coagulation. Preliminary studies using the human hepatoma cell line HepG2 are described, demonstrating that this compound has no effect upon cell viability or overall protein synthesis in these cells, and at high concentrations DNA synthesis as measured by radioactive thymidine incorporation is enhanced. Reduced intracellular concentration and secretion of apolipoprotein B have been shown to occur in response to resveratrol although a clear dose-dependency has not yet been demonstrated. The mechanisms underlying these changes as well as the effects upon the synthesis and secretion of other apolipoproteins are under active investigation in our laboratory.

Abstract
BACKGROUND Studies in men suggest that light-to-moderate alcohol intake is associated with a reduction in overall mortality, due primarily to a reduced risk of coronary heart disease. Among women with similar levels of alcohol consumption, an increased risk of breast cancer has been noted that complicates the balance of risks and benefits. METHODS We conducted a prospective study among 85,709 women, 34 to 59 years of age and without a history of myocardial infarction, angina, stroke, or cancer, who completed a dietary questionnaire in 1980. During the 12-year follow-up period, 2658 deaths were documented. RESULTS The relative risks of death in drinkers as compared with nondrinkers were 0.83 (95 percent confidence interval, 0.74 to 0.93) for women who consumed 1.5 to 4.9 g of alcohol per day (one to three drinks per week), 0.88 (95 percent confidence interval, 0.80 to 0.98) for those who consumed 5.0 to 29.9 g per day, and 1.19 (95 percent confidence interval, 1.02 to 1.38) for those who consumed 30 g or more per day, after adjustment for other predictors of mortality. Light-to-moderate drinking (1.5 to 29.9 g per day) was associated with a decreased risk of death from cardiovascular disease; heavier drinking was associated with an increased risk of death from other causes, particularly breast cancer and cirrhosis. The benefit associated with light-to-moderate drinking was most apparent among women with risk factors for coronary heart disease and those 50 years of age or older. CONCLUSIONS Among women, light-to-moderate alcohol consumption is associated with a reduced mortality rate, but this apparent survival benefit appears largely confined to women at greater risk for coronary heart disease.

Abstract
BACKGROUND AND PURPOSE Understanding the effects of alcohol intake on stroke and other cardiovascular diseases is an important issue for public health. METHODS A 10.5-year prospective study of the relationship between alcohol intake and cardiovascular disease incidence was conducted in 2890 men, aged 40 to 69 years and free of a history of stroke and coronary heart disease, in three rural communities of Japan. RESULTS One hundred seventy-eight strokes (40 intracerebral hemorrhages, 18 subarachnoid hemorrhages, 104 nonhemorrhagic strokes, and 16 unclassified strokes), 34 coronary heart disease events, and 19 sudden unclassified deaths occurred. Drinkers of > or = 70 g/d ethanol had an approximately 2.5 times higher age-adjusted risk of all stroke than never-drinkers; the excess risk was more evident for hemorrhagic stroke than nonhemorrhagic stroke. When hypertension category, serum total cholesterol level, cigarette smoking, and diabetes mellitus were taken into account, these excess risks were reduced but remained significant for all stroke (2.0; 95% confidence interval, 1.3 to 3.1) and hemorrhagic stroke (3.4; 95% confidence interval, 1.2 to 9.2). A J-shaped relationship was suggested between alcohol intake and risk of nonhemorrhagic stroke; drinkers of < 42 g/d ethanol had a slightly lower risk and heavy drinkers had a higher risk than never-drinkers. Current drinkers had a slightly lower risk of coronary heart disease than never-drinkers, although the risk difference was not statistically significant. The age-adjusted risk of sudden death was 10 times higher in heavy drinkers than never-drinkers, and the excess risk did not change when the covariates were controlled for. Total cardiovascular disease showed a similar pattern as did all stroke. CONCLUSIONS Heavy drinking appeared to increase the risk of hemorrhagic stroke, in part due to hypertension, and to increase the risk of sudden death, which was probably due to drinking per se. Light or moderate alcohol consumption seemed to protect against nonhemorrhagic stroke and coronary heart disease.

Abstract
A method is proposed for estimation of alcohol-caused mortality in which the aetiologic fraction of deaths is derived from an exposure contrast between the 'unsafe' drinker and 'safe' drinker; not between the drinker and the nondrinker. The method is consistent with the objectives of public health intervention in the alcohol education field. The 'safe' drinker is the reference exposure category and aetiologic fractions are obtained for the single categories of a multiple-level exposure scale, using separate relative risks for the 'unsafe' drinker and the nondrinker. Preliminary application of the method to Australian data yields an estimate of the number of deaths caused by misuse of alcohol that is larger than those obtained under the old conceptual model. Thus, the public health importance of unsafe alcohol consumption has been underrepresented.

Abstract
BACKGROUND AND PURPOSE The relationship between alcohol intake and stroke has been inconsistent in previous studies. We examined the separate and combined effects of drinking habits and hypertension on stroke incidence in a prospective survey of a general Japanese population. METHODS A total of 1621 stroke-free Hisayama residents aged 40 years or older were classified by their alcohol intake into nondrinkers, light drinkers (< 34 g of ethanol per day), and heavy drinkers (> or = 34 g of ethanol per day) and followed up prospectively for 26 years from 1961. RESULTS During the follow-up period, cerebral infarction developed in 244 subjects and cerebral hemorrhage in 60. For men, the incidence of cerebral hemorrhage increased significantly with rising alcohol consumption. In contrast, the incidence of cerebral infarction was slightly lower in light drinkers than in nondrinkers, while it increased significantly in heavy drinkers compared with light drinkers. Female drinkers had a lower incidence of cerebral infarction but a slightly higher incidence of cerebral hemorrhage than nondrinkers, as did male light drinkers. Among the hypertensive subjects, the age- and sex-adjusted relative risk of cerebral hemorrhage was significantly elevated in heavy drinkers versus abstainers (3.13; 95% confidence interval [CI], 1.08 to 9.10), but the increase was not significant for light drinkers. In contrast, the relative risk did not significantly increase for normotensive light and heavy drinkers. Compared with hypertensive light drinkers, the relative risk of cerebral infarction significantly increased in hypertensive heavy drinkers (1.96; 95% CI, 1.08 to 3.57) but remained unchanged in normotensive heavy drinkers. Significant associations between alcohol intake and stroke were substantially the same even after controlling for other risk factors in multivariate analysis. CONCLUSIONS Among hypertensive individuals, heavy alcohol consumption leads to a significant increase in the risk of cerebral hemorrhage, suggesting a synergistic effect of alcohol and hypertension, while light alcohol consumption significantly reduces the risk of cerebral infarction.

Abstract
BACKGROUND There are no published New Zealand (NZ) studies on alcohol drinking and total mortality, despite its importance to alcohol health policy. AIMS To estimate the proportion of NZ deaths caused or prevented by alcohol drinking. METHODS The proportion of current alcohol drinkers from recent NZ surveys, and pooled relative risks from a review of the international literature on alcohol and mortality, were used to calculate disease-specific population attributable risks. The number of deaths caused (or prevented) by alcohol were calculated for 1987 New Zealand deaths. Person-years of life lost (or saved) were calculated using recent NZ life tables. RESULTS The association between alcohol and total mortality was related to age. Alcohol was estimated to have caused 3.0% of all deaths among 0-14 year olds and 20.1% of deaths among 15-34 year olds, mostly from road injuries. In contrast, alcohol was estimated to have prevented 0.5% of all deaths among 35-64 year olds and 3.4% of deaths among > or = 65 year olds due to its protective effect against coronary heart disease. For all age groups, alcohol was estimated to have prevented 1.5% of deaths. However, the number of person-years of life lost among ages less than 35 years was greater than those saved in the older age groups, so that alcohol was estimated to have caused the loss of 9525 person-years of life for all ages combined. CONCLUSIONS The adverse effects of alcohol on total mortality are confined to age groups less than 35 years. Public health policy to minimise deaths from alcohol should be concentrated on this group.

Abstract
Data on the prevalence of chronic liver disease, derived from selected series of hospitalized patients or from mortality registers, underestimate the prevalence of chronic liver disease. The Dionysos Study is a cohort study that investigated for the first time the prevalence of chronic liver disease in a general population. All the citizens of two towns in northern Italy, Campogalliano and Cormons, aged 12 to 65 yr were contacted by letter. From March 1991 through March 1993, 6,917 of a total of 10,150 citizens were enrolled (compliance, 69%). The standardized protocol for each enrollee included (a) a color-illustrated food questionnaire on dietary habits and alcohol intake; (b) a detailed medical history, including questions on risk factors for chronic liver disease; (c) a physical examination; and (d) blood tests for AST, ALT, gamma-glutamyltranspeptidase, mean cell volume, platelet count and hepatitis B virus and hepatitis C virus markers. Signs suggestive of chronic liver disease were seen in 21.3% of the subjects, and who then underwent further liver function tests, upper abdominal ultrasonography and, when necessary, liver biopsy. Persistent signs of chronic liver disease were present in 17.5% of the subjects, including 1.1% with cirrhosis and 0.07% with hepatocellular carcinoma. The prevalence rates of hepatitis B virus and hepatitis C virus positivity (second-generation enzyme-linked immunosorbent assay) were 1.3% and 3.2%, respectively. Alcohol abuse was the etiological agent in 23%.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVES Alcohol involvement is common in many fatal injuries. This study examines drinking behavior in a nationally representative sample of US adult decedents aged 25 through 64 years and its association with cause of death. METHODS Proxy-reported information from the 1986 National Mortality Followback Survey was used to profile the decedents' usual frequency and quantity of drinking. The association of drinking behavior with underlying cause of death was assessed while adjusting for demographic characteristics. RESULTS Of the decedents, 17% were daily drinkers, 22% usually consumed five drinks or more per occasion, and 27% were classified as heavier drinkers. Persons who died of injury drank more frequently and heavily than those who died of disease. The adjusted odds ratio of injury's being the underlying cause of death was 1.4 (95% confidence interval [CI] = 1.1, 1.8) for daily drinkers, 1.5 (95% CI = 1.1, 2.0) for those drinking five or more drinks per occasion, and 1.4 (95% CI = 1.1, 1.7) for heavier drinkers. CONCLUSIONS Daily drinking, binge drinking, and heavier drinking were each associated with an increased likelihood of injury as the underlying cause of death. Persons who were young, male, Native American, or divorced or separated were more likely to drink frequently and heavily.

Abstract
BACKGROUND The study objective was to determine the association between reported alcohol consumption and total mortality, mortality from selected causes, and incident nonfatal chronic disease events in middle-aged (51 to 64 years old) and elderly (65 to 75 years old) men during an approximate 15-year follow-up period. METHODS AND RESULTS We conducted a prospective epidemiological study of Japanese-American men who were participating in the Honolulu Heart Program and were free from coronary heart disease, cerebrovascular disease, and cancer at baseline examination and at subsequent reexamination 6 years later. Self-reported alcohol consumption was determined twice: at the baseline examination in 1965 through 1968 and at reexamination approximately 6 years later (1971 through 1974). Four primary alcohol consumption groups who reported similar alcohol intake at the time of these two clinical examinations were considered: abstainers and light (1 to 14 mL of alcohol per day), moderate (15 to 39 mL of alcohol per day), and heavy (> or = 40 mL of alcohol per day) drinkers. Study end points were also determined in very light (1 to 4.9 mL of alcohol per day) drinkers and in men who reported a change in their alcohol intake between examinations. Longitudinal follow-up was carried out through the end of 1988 with determination of selected fatal and nonfatal events according to alcohol intake. After controlling for several potentially confounding factors, total mortality exhibited a J-shaped pattern in relation to alcohol consumption in middle-aged and elderly men. There was a trend for lower rates of occurrence of combined fatal and nonfatal coronary heart disease events with increasing alcohol consumption in both middle-aged and elderly men. Increasing alcohol consumption was related to an increased risk of fatal and nonfatal strokes in middle-aged men, whereas elderly light and moderate drinkers were at increased risk for fatal and nonfatal strokes. Heavy drinkers were at increased risk for fatal and nonfatal malignant neoplasms in the two age groups examined. CONCLUSIONS The results of this long-term prospective study provide a balanced perspective of the health effects of alcohol consumption in middle-aged and elderly men. High levels of alcohol consumption were shown to be related to an increasing risk of diseases of considerable public health importance. These findings suggest that caution be taken in formulating population-wide recommendations for increases in the population levels of alcohol consumed given the associated significant social and biological problems of high consumption levels.

Abstract
OBJECTIVE To examine the association between self reported alcohol intake and subsequent mortality from all causes and if the effect of alcohol intake on the risk of death is modified by sex, age, body mass index, and smoking. DESIGN Prospective population study with baseline assessment of alcohol and tobacco consumption and body mass index, and 10-12 years' follow up of mortality. SETTING Copenhagen city heart study, Denmark. SUBJECTS 7234 women and 6051 men aged 30-79 years. MAIN OUTCOME MEASURE Number and time of deaths from 1976 to 1988. RESULTS A total of 2229 people died, 1398 being men. A U shaped curve described the relation between alcohol intake and mortality. The lowest risk was observed at one to six alcoholic beverages a week (relative risk set at 1). Abstainers had a relative risk of 1.37 (95% confidence interval 1.20 to 1.56) whereas those drinking more than 70 beverages a week had a relative risk of 2.29 (1.75 to 3.00). Among the drinkers, the risk was significantly increased only among those drinking more than 42 beverages a week. Sex, age, body mass index, and smoking did not significantly modify the risk function. The risk among heavy drinkers was slightly reduced when smoking was controlled for. The risk function was similar in the first and second period of six years of observation. CONCLUSION Alcohol intake showed a U shaped relation to mortality with the nadir at one to six beverages a week. The risk function was not modified by sex, age, body mass index, or smoking and remained stable over 12 years.

Abstract
Although the mortality rate from coronary artery disease in Hong Kong is only one-fourth of that of northern Europe and the United States, the disease has been and remains the second major cause of death (after all cancers combined). Beginning in 1987, we have conducted a case-control study of acute myocardial infarction in four Hong Kong hospitals. This study, one of the biggest case-control studies conducted in the Chinese population of both men and women, confirms the importance of several risk factors--cigarette smoking, history of hypertension, history of diabetes, body fatness, and lack of physical activity--previously described in data collected in western populations. In addition, more adverse childhood experience was also found to be an important risk factor of acute myocardial infarction. Further research in appropriate intervention measures in education in the prevention and cessation of smoking, the control of blood pressure, diabetes, and overweight, and adequate exercise could significantly help reduce the risk of acute myocardial infarction in the Hong Kong Chinese population.
