Alcohol and breast cancer in an area with high alcohol consumption

The association between alcohol drinking and breast cancer risk was investigated in 132 breast cancer cases and 499 controls with acute conditions unrelated to alcohol or any of the suspected risk factors for breast cancer, in an area which shows among the highest levels of alcohol consumption and prevalence of alcohol-related diseases in Europe (i.e. Pordenone Province, Northeastern part of Italy). Compared with non-drinkers, the multivariate odds ratio (OR) for ever drinkers was 1.5 (95% confidence interval, CI: 0.8-2.6). The risks for wine (the almost exclusive source of alcohol in the present investigation) were 1.2 for up to 1 drink, 1.4 for up to two drinks, 1.9 for up to 3 and 1.6 for over 3 drinks per day. Time-related factors (i.e. drinking habit duration and age at start of drinking) did not seem to be risk indicators.     

Alcohol consumption and blood pressure

The relationship between alcohol consumption and systolic and diastolic blood pressure was examined in a representative population sample of 1,429 men and women aged 35-64 years in Auckland, New Zealand during 1982. Univariate plots demonstrated a U-shaped relationship between alcohol consumption and systolic and diastolic blood pressures in men and in women aged 50 years and older, with light and moderate drinkers (less than 0-34 g alcohol/day) having lower blood pressure levels than either nondrinkers or heavy drinkers. No clear relationship was seen in younger women. The U-shaped relationship in men, particularly for systolic blood pressure, remained after controlling for potential confounders, whereas in women aged 50 years and older, there appeared to be a threshold level of approximately four drinks per day, below which drinkers had similar blood pressure levels to nondrinkers. In the multivariate analyses, it was calculated that among men, light and moderate drinkers had systolic levels 4.8 mmHg lower and diastolic levels 1.7 mmHg lower than nondrinkers and heavy drinkers, while among women aged 50-64 years, nondrinkers, light drinkers, or moderate drinkers had systolic levels 10.2 mmHg lower and diastolic levels 4.5 mmHg lower than heavy drinkers. These findings suggest that in men and in women aged 50 years and older, there is a nonlinear relationship between blood pressure and alcohol consumption, and that there is a level of alcohol consumption, of approximately four drinks per day, below which drinkers have either similar or lower blood pressure levels compared to nondrinkers.     

Boissons alcooliques, poids et paramètres d’adiposité chez 520 adultes issus de l’étude Fleurbaix Laventie Ville Santé

Epidemiological studies show that alcohol consumption is associated with body weight and adiposity. Data from Fleurbaix Laventie Ville Santé study, a prospective epidemiological study on the relationships between health and nutrition, were used to explore the effect of total alcohol, wine or beer consumption on body weight and adiposity. A total of 520 subjects were included in this transversal analysis. Among women, light to moderate alcohol consumption is associated with a lower body weight and adiposity, adjusted for physical activity, smoking habits and age. Women who drinks one drink per week to one drink per day have better adiposity indicators than non-drinkers or drinkers of more than one drink per day. However, there is no relation between adiposity and specific consumption of beer or wine. Among men, there is no significant relation between total alcohol, beer or wine consumption and adiposity.     

The population attributable risk of hypertension from heavy alcohol consumption

The association between alcohol consumption and hypertension was studied in 11,899 men aged 40-55 years. The prevalence of hypertension among heavy drinkers was significantly higher than among those who did not drink heavily. Heavy drinking was defined as consumption of five or more drinks daily or four or more drinks daily. A total of 136 persons fulfilled the five drinks or more per day definition and 230, the four drinks daily definition. The population-attributable risk of hypertension contributed by heavy drinking, depending on the diagnostic criteria used to define each endpoint, varied from 3 to 12 percent. There is reason to suspect that the contribution of alcohol to hypertension in the general population may be somewhat higher at the present time than in the late 1950s when the study was conducted. Moderation of alcohol consumption, in addition to weight reduction and salt restriction, is another important nonpharmacological means to control hypertension.     

Alcohol consumption and the risk of type 2 diabetes mellitus: atherosclerosis risk in communities study

Evidence regarding the association between alcohol consumption and type 2 diabetes risk remains inconsistent, particularly with regard to male-female differences. The authors conducted a prospective study of type 2 diabetes risk associated with alcohol consumption in a cohort of 12,261 middle-aged participants of the Atherosclerosis Risk in Communities Study (1990-1998), who were followed between 3 and 6 years. Alcohol consumption at baseline was characterized into lifetime abstainers, former drinkers, and current drinkers of various levels. Incident diabetes was determined by blood glucose measurements and self-report. After adjustment for potential confounders, an increased risk of diabetes was found in men who drank >21 drinks/week when compared with men who drank < or =1 drink/week (odds ratio = 1.50, 95% confidence interval: 1.02, 2.20) while no significant association was found in women. This increased diabetes risk among men who drank >21 drinks/week was predominantly related to spirits rather than to beer or wine consumption. The relative odds of incident diabetes in a comparison of men who drank >14 drinks of spirits per week with men who were current drinkers but reported no regular use of spirits, beer, or wine were 1.82 (95% confidence interval: 1.14, 2.92). Results of this study support the hypothesis that high alcohol intake increases diabetes risk among middle-aged men. However, more moderate levels of alcohol consumption do not increase risk of type 2 diabetes in either middle-aged men or women.     

Alcohol drinking patterns differentially affect central adiposity as measured by abdominal height in women and men

Alcohol drinking in light-to-moderate amounts has been associated with reduced coronary heart disease (CHD) risk. However, there is evidence that the way people consume alcohol (drinking pattern) may affect risk. Central adiposity, a known CHD risk factor may be one mechanism in the pathway between alcohol consumption and CHD risk. Our study examined whether various drinking patterns differentially affect fat distribution, particularly abdominal fat in women and men. In a randomly selected population-based cohort (n = 2343), 35-79 y old, we assessed drinking pattern as reported for the past 30 d, including beverage type and amount, frequency of consumption, percentage of time drinking while eating and number of drinks consumed/drinking day. Central adiposity was determined using an abdominal caliper to measure supine height of the abdomen. Current drinkers tended to have smaller abdominal heights than nondrinkers (women, P < 0.0001; men, P = 0.0559). For drinking pattern, frequency was inversely associated, but drinking intensity (drinks/drinking day) was positively associated with central adiposity in women (P trend for frequency, 0.0007; intensity, 0.0010) and men (P trend for frequency, 0.0005; intensity, 0.0004), even when age, education, physical activity, smoking status and amount of alcohol (g) were included in the models. When frequency and intensity were considered together, daily drinkers of <1 drink/drinking day had the smallest mean abdominal height measures with the largest measures in less than weekly drinkers who consumed 4 or more drinks/drinking day. These results support the hypothesis that drinking pattern affects the distribution of body fat, an important CHD risk factor.     

The association between stress and drinking: modifying effects of gender and vulnerability

AIMS: To assess the relationship between number and type of past-year stressful experiences and alcohol consumption, with a focus on how gender, poverty, and psychological vulnerability moderate this association. METHODS: Data from 26 946 US past-year drinkers 18 years of age and over, interviewed in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), were used to construct multivariate linear regression models predicting six measures of drinking pattern and volume. RESULTS: There was a consistent positive relationship between number of past-year stressors experienced and all measures of heavy drinking. Frequency of heavy (5+ drinks for men; 4+ drinks for women) drinking increased by 24% with each additional stressor reported by men and by 13% with each additional stressor reported by women. In contrast, the frequency of moderate drinking (<5 drinks for men; <4 drinks for women) decreased as stress levels increased. Job-related and legal sources of stress were more strongly associated with alcohol consumption than were social and health-related stress. Men showed a stronger association than women between the number of stressors and the most consumption measures; they also responded more strongly to the presence of any legal and job-related stress. Having an income below the poverty level intensified the effects of job-related stress, but having a mood or anxiety disorder did not affect any of the associations between stress and consumption. CONCLUSIONS: Stress does not so much lead individuals to drink more often as to substitute larger quantities of alcohol on the days when they do drink. Treatment and brief interventions aimed at problem drinkers might benefit from addressing the issue of tension alleviation and the development of alternative coping mechanisms.     

Wine and other types of alcoholic beverages and the risk of esophageal cancer

OBJECTIVE: To investigate the separate and combined effect of wine-drinking and other alcoholic beverages on esophageal cancer, in a high wine-consuming population. DESIGN: Combined analysis of two hospital-based case-control studies. SETTING: Major teaching and general hospitals in the greater Milan area and in the province of Pordenone, in northern Italy. SUBJECTS: A total of 714 incident cases of esophageal cancer, and 3137 controls admitted to hospital for acute, non-neoplastic conditions, unrelated to alcohol consumption. INTERVENTION: Trained interviews identified and questioned cases and controls using standardized structured questionnaires, including information on the average number of days per week each type of alcoholic beverages (wine, beer, spirits) was consumed, and the average number of drinks per day. Odds ratios (ORs) were calculated using unconditional multiple logistic regression equations. RESULTS: With reference to total alcohol drinking, as compared to non- or moderate drinkers (<3 drinks per day), the multivariate ORs were 1.98 for drinkers of 3-4 drinks per day, 4.22 for 5-7, 7.60 for 8-11, and 12.35 for > or =12 drinks per day. Higher risks were observed for wine-only drinkers and the corresponding values were 1.70, 4.21, 8.76 and 17.90. After allowance for wine intake, no association was observed between beer and spirit drinking and esophageal cancer, in a population in which 80% of alcohol came from wine. CONCLUSION: The amount of ethanol determines the risk of esophageal cancer, and the most commonly used alcoholic beverage appear to be most strongly associated.     

Alcohol consumption and risk of prostate cancer: The Harvard Alumni Health Study

BACKGROUND: Although many studies suggest that consumption of alcohol increases the risk of several site-specific cancers, the evidence remains unclear for prostate cancer. Few data exist on beverage-specific associations as well as lifetime patterns of alcohol consumption and prostate cancer risk. METHODS: We prospectively followed 7612 Harvard alumni (mean age 66.6 years) from 1988 through 1993, during which 366 cases of incident prostate cancer occurred. Self-reported alcohol consumption was assessed at baseline from wine, beer, and liquor intake. Previous assessments during college and in 1977 were also available. RESULTS: Overall, the mean total alcohol consumption in 1988 was 123.1 g/week, of which 28.6% was from wine, 15.8% from beer, and 55.6% from liquor. Compared to men reporting almost never drinking alcohol in 1988, the multivariate relative risks (95% CI) for 1 drink/month to < 3 drinks/week, 3 drinks/week to < 1 drink/ day, 1 to < 3 drinks/day, and > or = 3 drinks/day were 1.33 (0.88-2.01), 1.65 (1.12-2.44), 1.85 (1.29-2.64), and 1.33 (0.86-2.05), respectively. Wine or beer consumption was unassociated with prostate cancer; however, moderate liquor consumption was associated with a significant 61-67% increased risk of prostate cancer (P, non-linear trend < 0.001). Men initiating alcohol consumption between 1977 and 1988 had a twofold increased risk of prostate cancer compared to men with almost no alcohol consumption at both times. CONCLUSIONS: In contrast to the majority of previous studies, we found a positive association between moderate alcohol consumption and the risk of prostate cancer. Liquor, but not wine or beer, consumption was positively associated with prostate cancer.     

Examining Australia's heaviest drinkers

Objective : This study examined the distribution of alcohol consumption in Australia, identifying the heaviest drinking 10% of the population and examining their sociodemographic characteristics and their alcohol consumption and purchasing practices. Methods : Data came from the 2016 National Drug Strategy Household Survey and the 2013 International Alcohol Control Study. The heaviest drinking 10% of the population identified based on estimates of annual alcohol consumption. Logistic regression was then used to assess the factors that distinguished these heaviest drinkers from the rest of the drinking population. Results : The heaviest drinking 10% of the population consumed 54.4% of all alcohol consumed. These heavy drinkers were more likely to be men and to live in regional and remote areas. They were more likely to drink cask wine and full‐strength beer and to purchase cheaper alcohol than other drinkers. Conclusions : Australian alcohol consumption is heavily skewed. Alcohol consumption practices appear to differentiate the heaviest drinkers from others more clearly than sociodemographic factors. Implications for public health : Public health interventions that reduce drinking among the heaviest 10% of drinkers in Australia have the potential to markedly reduce per‐capita consumption and reduce alcohol‐related harm. Interventions focused on cheap alcohol may be effective with these drinkers.     

Type of alcohol and drinking pattern in 56, 970 Danish men and women

OBJECTIVE: To describe drinking patterns among individuals who prefer drinking wine, beer or spirits. DESIGN: Cross-sectional study obtaining detailed information on intake of wine, beer and spirits and on frequency of alcohol intake. Adjustment for gender, age, smoking habits, educational attainment and body mass index. SETTING: Denmark. SUBJECTS: 27, 151 men and 29, 819 women, randomly selected from Copenhagen and Aarhus, Denmark. MAIN OUTCOME MEASURES: Drinking pattern-steady or binge drinking. RESULTS: A vast majority (71%) of both men and women preferred wine or beer. At all levels of total alcohol intake, beer drinkers were most likely to be frequent drinkers. Thus, light drinkers of beer had an odds ratio for being frequent drinkers of 1.97 (95% confidence limits 1.50-2.58) as compared to light drinkers of wine (total alcohol intake 3-30 drinks per month), while people who preferred beer had an odds ratio of 1. 29 (1.19-1.40) compared with wine drinkers in the moderate drinking category (31-134 drinks per month). There were no significant differences in total alcohol intake between individuals preferring different alcoholic beverages. CONCLUSION: If binge drinking is less healthy than steady drinking, the relation between wine intake and coronary heart disease mortality could be subject to negative confounding, since beer drinkers seem to have the most sensible drinking pattern.

Alcohol consumption in relation to 20-year COPD mortality and pulmonary function in middle-aged men from three European countries

Alcohol consumption shows a U-shaped relation with all-cause and cardiovascular mortality. To determine whether a similar relation exists between alcohol and chronic obstructive pulmonary disease mortality, we analyzed data on alcohol consumption in 1970 and 20-year mortality from chronic obstructive pulmonary disease among 2,953 middle-aged men from Finland, Italy, and the Netherlands. We also studied alcohol consumption in relation to pulmonary function (FEV1 or FEV0.75) at baseline. We used regression models adjusted for age, height (for pulmonary function only), body mass index, smoking habits, energy intake, and country. A smoothed spline-plot showed a U-shaped relation between alcohol and chronic obstructive pulmonary disease mortality. Compared with non-drinkers and occasional drinkers, the relative risk of chronic obstructive pulmonary disease mortality was 0.60 (95% CI = 0.33-1.09) in light drinkers (> 1 drink per week, < or = 3 drinks per day) and 1.25 (95% CI = 0.47-3.31) in moderate-to-heavy drinkers. Pulmonary function was lower in non-drinkers compared with occasional and light drinkers in Finland (75 ml, 95% CI = -2 to 151) and the Netherlands (93 ml, 95% CI = 0-186) and lower in very heavy (> 12 drinks per day) compared with moderate-to-heavy drinkers in Italy (99 ml, 95% CI = 9-189). In conclusion, we observed a U-shaped curve between alcohol consumption and 20-year chronic obstructive pulmonary disease mortality in middle-aged men that was supported by cross-sectional data on alcohol and pulmonary function.     

Changes in alcohol intake and mortality: a longitudinal population-based study

BACKGROUND: Using alcohol intake at one point in time, numerous studies have shown a J- or U-shaped relation with all-cause mortality. Mortality is lowest among the light to moderate drinkers, with the risk of dying from coronary heart disease higher among nondrinkers and the risk of dying from cancer higher among heavy drinkers. We studied whether changes in individual alcohol intake result in corresponding changes in mortality. METHODS: In a longitudinal study of 6644 men and 8010 women, age 25 to 98 years, who had attended at least 2 health surveys with a 5-year interval between them, we addressed the risk of death after combinations of changes in alcohol intake. RESULTS: Mortality after changes in alcohol intake was consistent with the mortality observed among those who reported stable drinking. Stable drinkers showed a U-shaped all-cause mortality, with relative risks of 1.29 (95% confidence interval [CI] = 1.13-1.48) for nondrinkers (< 1 drink per week) and 1.32 (1.15-1.53) for heavy drinkers (> 13 drinks per week) compared with light drinkers (1 to 6 drinks per week). For coronary heart disease mortality, stable nondrinkers had a relative risk of 1.32 (0.97-1.79) compared with stable light drinkers and those who had reduced their drinking from light to none increased their risk (1.40; 1.00-1.95), and those who had increased from nondrinking to light drinking reduced their relative risk ratio (0.71; 0.44-1.14). Cancer mortality was increased in all groups of heavy drinkers. CONCLUSION: Persons with stable patterns of light and moderate alcohol intake had the lowest all-cause mortality. Individual changes in alcohol intake were followed by corresponding changes in mortality.     

Alcohol consumption in young adults in the rural communities of Spain.

In the spring of 1987, the patterns of alcohol consumption in 1,886 young people (14-30 years old) from the rural communities (less than 10,000 inhabitants) of Castile and León (Spain) were analysed. 64.1% of the young adults took alcoholic drinks at least once a week, while 24.4% were 'daily' consumers. Beer (56%) was the preferred drink, followed by gin (22.4%) and wine (21.3%). The age of starting to drink was close to 16 years old and the alcohol intake per capita was 19 g/day. Both frequency and intake were higher among males and at weekends. The main reported reason for drinking was 'because I like its taste' (39.1%). The results confirm the common consumption of alcoholic drinks among Spanish young adults, the establishment of beer as the preferred drink and the more extensive consumption of alcohol by males and at weekends.     

Hazardous alcohol drinking in the former Soviet Union: a cross-sectional study of eight countries

BACKGROUND: Hazardous consumption of large quantities of alcohol is a major cause of ill-health in the former Soviet Union (fSU). The objective of this study was to describe episodic heavy drinking and other hazardous drinking behaviors in eight countries of the fSU. METHODS: Data from national surveys of adults conducted in Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, and Ukraine in 2001 were used (overall sample size 18,428; response rates 71-88%). Heavy episodic drinking, high alcohol intake, drinking alcohol during the working day, and using illegally produced strong spirits were examined. RESULTS: On average, 23% of men and 2% of women were defined as heavy episodic drinkers (> or = 2 l of beer or > or = 750 g bottle of wine or > or = 200 g strong spirits at least once every 2-3 weeks). This was more common in young males, women who are single or who are divorced/separated/widowed, in smokers, and in frequent alcohol drinkers. About half the respondents who drank strong spirits obtained at least some alcohol from private sources. Among drinkers, 11% of males and 7% of women usually took their first drink before the end of working day. CONCLUSIONS: Heavy episodic alcohol drinking is frequent in males throughout the region--although prevalence rates may have been affected by underreporting--but is still relatively rare in women. Alcohol policies in the region should address hazardous drinking patterns and the common use of illegally produced alcohol.     

Moderate alcohol consumption and primary cardiac arrest

To determine if light to moderate consumption of alcohol influences the risk of primary cardiac arrest, the authors investigated 152 cases, 25-75 years of age, without prior heart disease or co-morbidity, in whom a primary cardiac arrest occurred during a 14-month period in King County, Washington state, December 1979-January 1981. Spouses of cases and those of 152 demographically similar residents of King County were interviewed to quantify average alcohol consumption over the prior year for beer, wine, and spirits combined. After adjustment for hypertension, smoking, and physical activity, light to moderate alcohol consumption was associated with a reduced risk of primary cardiac arrest. Compared to persons who were nondrinkers (less than 1 drink/month), the estimated relative risk for light drinkers (greater than or equal to 1 drink/month but less than 1 drink/day) was 0.7 (95% confidence interval, 0.5-1.0), and for moderate drinkers (1-3 drinks/day), 0.5 (95% confidence interval, 0.3-1.0). These data are consistent with the hypothesis that light to moderate alcohol consumption reduces the risk of primary cardiac arrest.     

What Do Binge Drinkers Drink?: Implications for Alcohol Control Policy

BACKGROUND: Although binge drinking (drinking five or more drinks on an occasion) is an important public health problem, little is known about which beverage types are consumed by binge drinkers. This knowledge could guide prevention efforts because beer, wine, and liquor are taxed, marketed, and distributed differently. METHODS: Data from 14,150 adult binge drinkers who responded to the Behavioral Risk Factor Surveillance System binge-drinking module in 2003 and 2004 were analyzed. Information pertained to the amount of alcohol consumed during a binge drinker's most recent binge episode, including beverage-specific consumption. RESULTS: Overall, 74.4% of binge drinkers consumed beer exclusively or predominantly, and those who consumed at least some beer accounted for 80.5% of all binge alcohol consumption. By beverage type, beer accounted for 67.1%, liquor for 21.9%, and wine accounted for 10.9% of binge drinks consumed. Beer also accounted for most of the alcohol consumed by those at highest risk of causing or incurring alcohol-related harm, including people aged 18-20 years (67.0% of drinks were beer); those with three or more binge episodes per month (70.7%); those drinking eight or more drinks per binge episode (69.9%); those binging in public places (64.4%); and those who drove during or within 2 hours of binge drinking (67.1%). CONCLUSIONS: Beer accounted for two thirds of all alcohol consumed by binge drinkers and accounted for most alcohol consumed by those at greatest risk of causing or incurring alcohol-related harm. Lower excise taxes and relatively permissive sales and marketing practices for beer as compared with other beverage types may account for some of these findings. These findings suggest that equalizing alcohol control policies at more stringent levels would be an effective way to prevent excessive drinking.     

Alcohol consumption and the risk of acute myocardial infarction in women.

STUDY OBJECTIVE--To investigate the relationship between alcohol consumption and the risk of acute myocardial infarction in women. DESIGN--This was a hospital based, case-control study carried out between 1983 and 1990. Main outcome measures were average daily number of drinks of various alcoholic beverages consumed and corresponding multivariate relative risk estimates and 95% confidence intervals (CI). SETTING--A network including major teaching and general hospitals in northern Italy. SUBJECTS--Cases were 298 women with acute myocardial infarction but no history of ischaemic heart disease and controls 685 women admitted to hospital for acute conditions, unrelated to alcohol consumption or to known or suspected risk factors for ischaemic heart disease. MEASUREMENTS AND MAIN RESULTS--Compared with non-drinkers, the estimated relative risks (RR) were 0.7 (95% CI 0.5, 1.0) for one drink or less per day, 0.8 (95% CI 0.6, 1.2) for more than one to two drinks per day, 1.4 (95% CI 0.8, 2.3) for more than two to three, and 2.6 (95% CI 1.5, 4.6) for more than three drinks per day. These estimates were consistent across strata of selected covariates, including age, education, and smoking. Allowance for major identified risk factors for myocardial infarction did not materially modify the risk estimate for light drinkers (RR 0.7, 95% CI 0.5, 1.1), but reduced the RR in heavy drinkers to 1.8 (95% CI 0.9, 3.5). CONCLUSIONS--This study indicates that women who do not drink alcohol have a risk of myocardial infarction that is higher than that of light drinkers, although the protection of light drinking was not significant. Among drinkers, however, there was a significant direct trend in risk with dose. The raised risks in heavy drinkers may reflect a real association or result from other unfavourable characteristics or habits associated with high alcohol consumption.     

Prospective study of alcohol consumption and metabolic syndrome

BACKGROUND: Alcohol consumption is related to the prevalent metabolic syndrome. Few studies have evaluated the effects of alcohol consumption on the development of metabolic syndrome. OBJECTIVE: We examined the association between alcohol consumption and incident metabolic syndrome. DESIGN: This was a prospective cohort study of 3833 male and female Koreans aged 40-69 y and free of the metabolic syndrome at baseline. Information on alcohol consumption was obtained periodically from interviewer-administered questionnaires. Incident cases of the metabolic syndrome were identified by biennial health examinations during 4 y of follow-up between 2003 and 2006. RESULTS: Compared with nondrinkers, the multivariate relative risk [RR (95% CI)] of the metabolic syndrome for very light drinkers consuming 0.1 to 5 g of alcohol per day (g/d) was 1.06 (0.71, 1.58), that for light drinkers consuming 5.1 to 15 g/d was 1.13 (0.69, 1.83), that for moderate drinkers consuming 15.1 to 30 g/d was 1.25 (0.75, 2.09), and that for heavy drinkers consuming >30 g/d was 1.63 (1.02, 2.62). All individual components of the metabolic syndrome were significantly associated with heavy drinking, particularly among heavy liquor drinkers. CONCLUSIONS: Heavy drinking, in particular among liquor drinkers, is associated with an increased risk of the metabolic syndrome by influencing its components. Further data are warranted to clarify the association between drinking minimal alcohol and the metabolic syndrome as well as the beverage-specific association for drinking beer or wine.     

Alcohol and breast cancer

We examined breast cancer incidence in a cohort of about 69,000 women who answered detailed questions about alcohol consumption from 1979 to 1984. Among women with no prior cancer, breast cancer had developed in 303 by the end of 1984 for an age-adjusted incidence of 1.3/1,000 person years of follow-up. In analysis controlling only for age there was a progressive increase in breast cancer incidence corresponding to each higher level of reported alcohol consumption. In multivariate analyses controlling for age, race, body mass, and smoking, the relative risk at 1-2 drinks/day was 1.5 (95% confidence interval (CI) 1.0-2.3), at 3-5 drinks/day was 1.5 (95% CI 0.8-2.8), and at 6 or more drinks/day was 3.3 (95% CI 1.2-9.3). Past drinkers tended to have been heavier drinkers than current drinkers and had a relative risk of 2.2 (95% CI 1.2-3.9). Study of wine, beer, and liquor use did not suggest that any particular alcoholic beverage was responsible. Significant associations with heavy alcohol consumption were strongest among white and postmenopausal women. This study adds support to the growing evidence that alcohol may be a risk factor for development of breast cancer.
