Alcohol and Self-Rated Health in a Mediterranean Country: The Role of Average Volume, Drinking Pattern, and Alcohol Dependence

Background: The association between average alcohol consumption and self‐rated ill‐health is “J‐shaped” in Scandinavian and Anglo‐Saxon countries, but it has shown an inverse linear relationship in the few studies conducted in Mediterranean countries, based on average volume solely. Objective: To examine the relationship between alcohol and self‐rated health in the general population of a Mediterranean country, by simultaneously taking into account average volume, drinking pattern, and alcohol abuse. Methods: From 2000 to 2005, we conducted telephone interviews on 12,037 persons, representative of the population aged 18 to 64 years in Madrid, Spain. The drinking pattern encompassed binge drinking, beverage preference, and drinking at mealtimes. Alcohol abuse was estimated by the CAGE test. The association between each alcohol‐related variable and self‐rated suboptimal (fair, poor, or very poor) health was estimated from logistic regression, with adjustment for the remaining alcohol‐related variables and other potential confounders. Results: In comparison with never‐drinkers, suboptimal health was less frequent among occasional drinkers [odds ratio (OR) 0.72; 95% confidence interval (CI): 0.61 to 0.86], average moderate drinkers (OR 0.57; 95% CI: 0.48 to 0.69), and excessive drinkers (OR 0.51; 95% CI: 0.36 to 0.72), but more frequent among former drinkers with ≥1 year of abstinence (OR 1.30; 95% CI: 1.03 to 1.64). Frequency of suboptimal health was likewise higher in subjects with ≥3 episodes of binge drinking (OR 1.55; 95% CI: 1.12 to 2.14) or alcohol abuse (OR 1.47; 95% CI: 1.22 to 1.76). No differences were observed in suboptimal health according to beverage preference or drinking at mealtimes. Results in each gender were similar to those for total study participants. Conclusions: Occasional, moderate, and excessive consumption of alcohol are associated with better self‐rated health, even after adjustment for drinking pattern and alcohol abuse. In contrast, former‐drinking, frequent binge drinking, and alcohol abuse are all associated with suboptimal self‐rated health.     

Patterns of alcohol consumption and alcohol-impaired driving in the United States

Background:  Alcohol-related motor vehicle crashes kill approximately 17,000 Americans annually and were associated with more than $51 billion in total costs in 2000. Relatively little is known about the drinking patterns of alcohol-impaired (AI) drivers in the United States.
Methods:  2006 Behavioral Risk Factor Surveillance System (BRFSS) was analyzed for alcohol consumption and self-reported AI driving among U.S. adults aged ≥18 years for all states. Alcohol consumption was divided into 4 categories: binge/heavy, binge/nonheavy, nonbinge/heavy, and nonbinge/nonheavy. Binge drinking was defined as ≥5 drinks for men or ≥4 drinks for women on one or more occasions in the past month, and heavy drinking was defined as average daily consumption of >2 drinks/day (men) or >1 drink/day (women). The prevalence of AI driving was examined by drinking pattern and by demographic characteristics. Logistic regression analysis was used to assess the association between drinking patterns and AI driving.
Results:  Five percent of drinkers were engaged in AI driving during the past 30 days. Overall, 84% of AI drivers were binge drinkers and 88% of AI driving episodes involved binge drinkers. By drinking category, binge/nonheavy drinkers accounted for the largest percentage of AI drivers (49.4%), while binge/heavy drinkers accounted for the most episodes of AI driving (51.3%). The adjusted odds of AI driving were 20.1 (95% CI: 16.7, 24.3) for binge/heavy, 8.2 (6.9, 9.7) for binge/nonheavy, and 3.9 (2.4, 6.3) for nonbinge/heavy drinkers, respectively.
Conclusions:  There is a strong association between binge drinking and AI driving. Most AI drivers and almost half of all AI driving episodes involve persons who are not heavy drinkers (based on average daily consumption). Implementing effective interventions to prevent binge drinking could substantially reduce AI driving.     

A new measure of binge drinking: prevalence and correlates in a probability sample of undergraduates

BACKGROUND: A standard measure defines binge drinking as the consumption of 5 or more drinks in a row for men (4 or more drinks for women) on at least 1 occasion during the past 2 weeks. A revised operational definition of binge drinking was developed by the National Institute on Alcohol Abuse and Alcoholism in 2004 and incorporated the duration of the drinking episode in addition to the quantity of alcohol consumed. This study compares the standard and new binge measures for overall and subgroup prevalence rates; associations with gender, race/ethnicity, and age of drinking onset; and associations with negative drinking consequences. METHODS: A probability sample of 4,580 randomly selected college students (50.3% female, M age=19.9, SD=2.0) at a large Midwestern university in the United States completed a Web-based survey of alcohol and other drug use. Participants reported on past 2-week binge drinking using the standard measure and past-year binge drinking using the new measure. RESULTS: The longer past-year time frame of the new measure yielded a higher prevalence estimate of binge drinking (63.6%) compared with the 2-week standard measure (53.2%). Approximately 9.9% of those who were classified as binge drinkers using the 2-week standard measure were classified as non-binge drinkers using the new measure specification of a 2-hour duration for the drinking episode. The past-year new binge measure was positively associated with negative drinking consequences even when the 2-week measure was statistically controlled. CONCLUSIONS: Using a longer time frame and incorporating the duration of the drinking episode, the new measure of binge drinking appears to capture an important element of risky alcohol involvement in college students that is not fully assessed by the standard measure.     

Revising the preventive paradox: the Swiss case

Aims. To examine Kreitman's preventive paradox of alcohol consumption and its revisions by Stockwell and colleagues and by Skog, with regard to alcohol‐related social harm in Switzerland, and to shed light on the reporting of alcohol‐related social harm in the low‐volume drinking, non‐bingeing subpopulation. The paper compares occurrence and severity of social harm in four subgroups defined by average consumption (volume) and binge drinking. Stage‐of‐change membership was used to further distinguish low‐risk drinkers who might have changed their drinking patterns from those who had not. Design, setting, and participants. Telephone interviews were conducted with 1256 current drinkers of a probabilistic two‐stage sample of the general population of Switzerland. Moderate and hazardous mean consumption (volume) was defined by means of a quantity‐frequency instrument. Daily average consumption of 20 g was set as the cut‐off point for women, and 30 g for men. Binge drinking was defined as taking four or more drinks on an occasion for women, and five or more for men. Structural equation modelling was used to construct a severity scale of six alcohol‐related consequences: work problems, accidents and problems with the police, with friends, with a partner or with the family. Explanatory factor analysis was used to assign drinkers to motivational stages of change. Findings. Moderate drinkers in terms of volume reported more problems than hazardous drinkers, which confirms Kreitman's view. Binge drinkers reported more problems than non‐binge drinkers, confirming the view of Stockwell and colleagues. Binge drinkers were more numerous in the moderate drinking group, which constituted the majority of drinkers, in accordance with Skog's view. Binge drinkers in the moderate‐volume and hazardous‐volume drinking groups did not differ significantly as to either severity or number of problems. Approximately 40% of moderate‐volume, non‐binge drinkers who reported alcohol‐related social harm had already changed their consumption pattern, which indicated that reported harm was related to an earlier drinking pattern. Conclusions. As Skog has pointed out, the second‐order preventive paradox of binge drinking reappeared, in that most binge drinkers were found to occur in the drinker group with low average consumption. Findings also indicate that, with respect to social harm, a preventive strategy aimed at the majority of the population, but on heavy‐drinking occasions rather than on mean consumption, may be valuable.     

Many college freshmen drink at levels far beyond the binge threshold

BACKGROUND: Binge drinking is a dichotomous variable that allows researchers to sort students into categories based upon a specific threshold of consumption, commonly 4 (females) or 5 (males) drinks. Crossing the binge threshold increases the risk of negative alcohol-related consequences. The use of such thresholds has played a vital role in the study of college drinking. While extremely valuable, the dichotomous nature of binge drinking variables removes information about how heavily students actually drink, leaving the characterization of college drinking incomplete. The present study examined patterns of alcohol use beyond the binge threshold. METHODS: The data set consisted of self-reported 2-week drinking histories from 10,424 first-semester freshmen at 14 schools across the United States during the fall of 2003. The number of students who reached the 4+/5+ binge-drinking threshold was calculated, as was the number who reached 2 times (8+/10+ drinks) or 3 times (12+/15+ drinks) the binge threshold. Logistic regression analyses were used to explore gender differences and to assess whether frequent binge drinkers (3+ binges per 2 weeks) were more likely than infrequent binge drinkers (1-2 binges per 2 weeks) to reach high peak levels of consumption. RESULTS: Roughly 1 of 5 males consumed 10+ drinks and 1 of 10 females consumed 8+ drinks, twice the binge threshold, at least once in the previous 2 weeks. Gender differences were observed at every drinking level and were particularly large at higher peak levels. Frequent binge drinkers were more likely than infrequent binge drinkers to consume 2 or 3 times the binge threshold. DISCUSSION: A surprisingly large percentage of students, particularly males, drink at peak levels well beyond the binge threshold. Such findings suggest that schools might make additional progress in the battle against alcohol misuse by focusing on extreme drinking practices in addition to binge drinking per se.     

The distribution of alcohol consumption and the prevention paradox in Brazil

Aims To examine the proportion of self‐reported alcohol consumed by different gender and age groups in Brazil over the past year, and to examine whether the ‘prevention paradox’ applies to Brazilian data on alcohol‐related problems. Design A multi‐stage cluster sample, representative of the Brazilian household population. Setting This study was conducted in Brazil between November 2005 and April 2006. Participants Respondents were aged ≥ 14 years (n = 3007). Measurements Measures included past year estimates of (i) number of standard drinks, (ii) frequency of binge drinking, and (iii) alcohol‐related problems. Findings The survey response rate was 66.4%. The top 2.5% of the drinkers by volume consume 14.9%, the top 5% consume 27.4% and the top 10% consume 44.2% of all alcohol consumed in Brazil. Men consume 77.8% of the total alcohol, and 18–29‐year‐olds consume 40.3%. Individuals below risky drinking guidelines for weekly volumetric intake account for 49–50% of all problem drinkers and 45–47% of all problem types reported. Individuals who do not binge or who binge infrequently (1–3 times/year) account for 50–51% of all problem drinkers and 45–46% of all reported problem types. Most binge drinkers are low‐volume drinkers. Conclusions Consistent with the prevention paradox literature, most drinking problems in Brazil are associated with low or moderate drinking. Binge drinking accounts more clearly for the distribution of alcohol problems than total volume consumed.     

Alcohol drinking patterns and biomarkers of coronary risk in the Spanish population

Background and aimsTo estimate the association between patterns of alcohol consumption and biomarkers of coronary heart disease (CHD) risk.Methods and resultsCross-sectional study among 10,793 individuals representative of the Spanish population aged ≥18 years. The threshold between moderate and heavy drinking was 40 g of alcohol/day in men and 24 g/day in women. Binge drinking was defined as intake of ≥80 g of alcohol in men and ≥60 g in women at any drinking occasion in the preceding 30 days. Analyses were performed with generalized linear models with adjustment for the main confounders, and results were expressed as the percentage change in the geometric mean (PCGM). Compared to non-drinkers, moderate and heavy drinkers had progressively higher serum HDL-cholesterol, with a PCGM ranging from 4.8% (95% CI: 3.7–6.0%) in moderate drinkers without binge drinking (MNB) to 9.6% (5.1–14.2%) in heavy drinkers with binge drinking (HB). Fibrinogen decreased progressively with alcohol intake, from −2.2% (−3.1 to −1.3%) in MNB to −5.8% (−9.4 to −2.0%) in HB. Leptin, glycated hemoglobin and the HOMA-index also decreased with increasing alcohol intake, and particularly with binge drinking.ConclusionsModerate alcohol intake is associated with improved HDL-cholesterol, fibrinogen and markers of glucose metabolism, which is consistent with the reduced CHD risk of moderate drinkers in many studies. Heavy and binge drinking were also associated with favorable levels of CHD biomarkers; since these drinking patterns produce substantial health harms, our results should not be used to promote alcohol consumption.     

Hostility, drinking pattern and mortality

AIMS: This study examined the association of hostility to drinking pattern and whether this association mediated the relation of hostility to mortality. PARTICIPANTS AND DESIGN: Subjects were 3326 current drinkers from the Vietnam Experience Study cohort who were followed for vital status. SETTING: United States. MEASUREMENTS: Hostility was measured by an abbreviated version of the Cook-Medley Hostility Scale (ACM). The alcohol variables were total monthly intake of alcohol, drinking frequency, drinks per drinking day and drinking > or = 5 drinks on at least one occasion in the past month (i.e. heavy episodic drinking). FINDINGS: Regression analyses showed associations between the ACM and total monthly intake of alcohol (P < 0.0001), drinks per drinking day (P < 0.0001) and heavy episodic drinking (P < 0.0001), but not with frequency of drinking days. Hostility, drinks per drinking day, heavy episodic drinking and total monthly alcohol intake were also associated with all-cause mortality (all Ps < 0.0001). Further analyses showed that drinking pattern, particularly drinks per drinking day, may account partially for the relation of hostility to mortality. CONCLUSIONS: High hostility is associated with elevated mortality and a deleterious drinking pattern characterized by relatively high intake per drinking occasion. Drinking pattern could help explain the relationships between hostility and health.     

The Hispanic Americans Baseline Alcohol Survey (HABLAS): Is the “Prevention Paradox” Applicable to Alcohol Problems Across Hispanic National Groups?

Background: The “prevention paradox,” a notion that most alcohol‐related problems are generated by nonheavy drinkers, has significant relevance to public health policy and prevention efforts. The extent of the paradox has driven debate over the type of balance that should be struck between alcohol policies targeting a select group of high‐risk drinkers versus more global approaches that target the population at‐large. This paper examines the notion that most alcohol problems among 4 Hispanic national groups in the United States are attributable to moderate drinkers. Methods: A general population survey employing a multistage cluster sample design, with face‐to‐face interviews in respondents’ homes was conducted in 5 metropolitan areas of the United States. Study participants included a total of 2,773 current drinkers 18 years and older. Alcohol consumed in the past year (bottom 90% vs. top 10%), binge drinking (binge vs. no binge), and a 4‐way grouping defined by volume and binge criteria were used. Alcohol‐related harms included 14 social and dependence problems. Results: Drinkers at the bottom 90% of the distribution are responsible for 56 to 73% of all social problems, and for 55 to 73% of all dependence‐related problems reported, depending on Hispanic national group. Binge drinkers are responsible for the majority of the social problems (53 to 75%) and dependence‐related problems (59 to 73%), also depending on Hispanic national group. Binge drinkers at the bottom 90% of the distribution are responsible for a larger proportion of all social and dependence‐related problems reported than those at the top 10% of the volume distribution. Cuban Americans are an exception. Conclusions: The prevention paradox holds when using volume‐based risk groupings and disappears when using a binge‐drinking risk grouping. Binge drinkers who drink moderately on an average account for more harms than those who drink heavily across all groups, with exception of Cuban Americans.     

The relationship between recent alcohol use and sexual behaviors: gender differences among sexually transmitted disease clinic patients

Background: Binge drinking is associated with risky sexual behaviors and sexually transmitted diseases (STDs). Few studies have investigated this by gender or in an STD clinic. This cross‐sectional study examined the association between binge drinking and risky sexual behaviors/STDs among patients attending an urban STD clinic. Method: A total of 671 STD clinic patients were tested for STDs, and queried about recent alcohol/drug use and risky sexual behaviors using audio computer‐assisted‐self‐interview. The association between binge drinking and sexual behaviors/STDs was analyzed using logistic regression adjusting for age, employment, and drug use. Results: Binge drinking was reported by 30% of women and 42% of men. Gender differences were found in rates of receptive anal sex which increased linearly with increased alcohol use among women but did not differ among men. Within gender analyses showed that women binge drinkers engaged in anal sex at more than twice the rate of women who drank alcohol without binges (33.3% vs. 15.9%; p < 0.05) and 3 times the rate of women who abstained from alcohol (11.1%; p < 0.05). Having multiple sex partners was more than twice as common among women binge drinkers than women abstainers (40.5% vs. 16.8%; p < 0.05). Gonorrhea was nearly 5 times higher among women binge drinkers compared to women abstainers (10.6% vs. 2.2%; p < 0.05). The association between binge drinking and sexual behaviors/gonorrhea remained after controlling for drug use. Among men, rates of risky sexual behaviors/STDs were high, but did not differ by alcohol use. Conclusion: Rates of binge drinking among STD clinic patients were high. Among women, binge drinking was uniquely associated with risky sexual behaviors and an STD diagnosis. Our findings support the need to routinely screen for binge drinking as part of clinical care in STD clinics. Women binge drinkers, in particular, may benefit from interventions that jointly address binge drinking and risky sexual behaviors. Developing gender‐specific interventions could improve overall health outcomes in this population.     

Exploring pregnancy-related changes in alcohol consumption between black and white women

Background: Although epidemiological data indicate that White women are more likely to drink and binge drink before pregnancy, fetal alcohol syndrome (FAS) is more common in the Black population than among Whites in the United States. Differences in drinking cessation between Black and White women who become pregnant may help explain the disparity in FAS rates. Methods: The study sample was comprised of 280,126 non‐Hispanic Black and White women, ages 18 to 44, from the Behavioral Risk Factor Surveillance System (BRFSS) 2001 to 2005 data sets. Predictors of reduction in alcohol consumption (in drinks per month) and binge drinking (>4 drinks on one occasion) by pregnant and non‐pregnant women were identified with logistic regression. The effect of interactions of pregnancy status with age, education, and Black or White race on drinks per month and binge occasions were explored using analysis of variance (ANOVA). Results: Pregnant White women averaged 79.5% fewer drinks per month than non‐pregnant White women (F = 1250.1, p < 0.001), and 85.4% fewer binge drinking occasions (F = 376, p < 0.001). Pregnant Black women averaged 58.2% fewer drinks per month than non‐pregnant Black women (F = 31.8, p < 0.001) and 64.0% fewer binge occasions (F = 13.8, p < 0.001). Compared to Black women, White women appear to make a 38% greater reduction in drinks per month, and a 33% greater reduction in binge occasions. Conclusions: Non‐Hispanic White women appear more likely to reduce drinks per month and binge drinking occasions than non‐Hispanic Black women during pregnancy. These findings may help explain disparities in FAS in the United States, though this cross‐sectional sample does not permit claims of causation. To better describe the impact of differential drinking reduction on FAS rates, future studies of longitudinal data should be done.     

Is There a Relationship Between Excessive Drinking and Functional Impairment in Older Persons?

OBJECTIVES: To investigate the relationship between (1) two thresholds of excessive alcohol drinking, (2) binge drinking, and (3) impairments in functional status in older drinkers. DESIGN: Cross-sectional study. SETTING: Ten internal medicine practices affiliated with an academic medical center. PARTICIPANTS: One hundred sixty-one persons aged 60 and older who reported drinking one or more drinks in the previous 3 months. MEASUREMENTS: Two commonly used thresholds of excessive drinking: (1) eight to 14 drinks per week for women and men (lower threshold) and (2) more than 14 drinks per week for women and men (higher threshold); a measure of binge drinking (> or =3 drinks per occasion for women or > or =4 drinks per occasion for men); and self-reported instrumental activities of daily living (IADLs) and advanced activities of daily living (AADLs). RESULTS: Compared with older persons consuming seven or fewer drinks per week, those exceeding the higher threshold of excessive drinking were more likely to have impairments in IADLs (adjusted odds ratio (AOR) = 8.4) and, to a lesser extent, AADLs (AOR = 3.7); those exceeding the lower threshold were more likely to have impairments in IADLs (AOR 5 6.0) but not in AADLs (AOR = 1.7). Binge drinkers were also more likely to have impairments in IADLs (AOR = 3.0) but not in AADLs (AOR = 1.5). CONCLUSIONS: In this group of older men and women, drinking more than seven drinks per week was associated with impairments in IADLs and, to a lesser extent, AADLs. Drinking more than three drinks per occasion was associated with impairments in IADLs.     

The association between alcohol consumption patterns and adherence to food consumption guidelines

Objective: To examine the association between alcohol consumption patterns and adherence to major food consumption guidelines in adults in Spain. Methods: Telephone survey of 12,037 persons, representative of the population age 18 to 64 years in the region of Madrid, conducted from 2000 to 2005. The threshold between average moderate and excessive drinking was 40 g alcohol/d in men and 24 g/d in women. Binge drinking was defined as intake of ≥80 g alcohol in men and ≥60 g in women during 1 drinking session in the last 30 days. Food consumption was measured with a 24‐hour recall. Statistical analyses were performed using logistic regression and adjusted for the main confounders. Results: In total, 4.3% of study participants were excessive drinkers and 10.3% binge drinkers; 6.5% preferred spirits and 24.2% drank with meals. In comparison with never drinking, average moderate drinking with binge drinking was associated with excessive meat consumption (>1 serving/d). Excessive alcohol consumption without binge drinking was associated with insufficient intake of milk products (<2 servings/d) and excessive consumption of meat, fish, and eggs (>2 servings/d). Excessive drinkers with binge drinking more often did not meet the guidelines on consumption of fruit and vegetables (<3 servings/d), milk products, and meat. Excessive drinkers, with and without binge drinking, were more likely to skip a meal, especially breakfast. Consumption mainly of spirits was associated with insufficient fruit and vegetable consumption, and with skipping a meal. Finally, drinking at mealtimes was associated with poor adherence to most of the food consumption guidelines. No dietary differences between men and women were found in relation to alcohol consumption. Conclusions: Average excessive alcohol consumption, binge drinking, preference for spirits, and drinking alcohol at mealtimes are associated with poor adherence to major food consumption guidelines.     

Defining “Binge” Drinking as Five Drinks per Occasion or Drinking to a .08% BAC: Which Is More Sensitive to Risk?

Heavy episodic or "binge" drinking is commonly defined as drinking 4-5 drinks per occasion (5/4 definition) or drinking that results in a blood alcohol concentration (BAC) of .08%. The present study compared the validity of each binge definition as an indicator of at-risk, problem drinking. Two hundred and fifty-one college students were classified as nonbinge drinkers or as binge drinkers based on the 5/4 definition or the .08% BAC definition. The two definitions of binge drinking were examined in terms of their sensitivity and specificity as indicators of alcohol-related problems as determined by scores on the Alcohol Use Disorders Identification Test (AUDIT). Over half the sample (56%) were at-risk drinkers according to the AUDIT. The .08% definition detected only one-half of these individuals. Gender differences were also evident. Female binge drinkers actually achieved significantly higher estimated BACs per episode than their male binge drinking counterparts. The findings suggest that drinking to a subthreshold BAC (ie, <.08%) is not sufficient to avoid alcohol-related problems, and that total quantity (ie, total standard drinks) per occasion might contribute to risk independent of the BAC achieved during drinking episodes. The findings also highlight the importance of considering frequency of consumption in determining risky drinking versus relying solely on quantity measures.     

Binge drinking in Madrid, Spain

BACKGROUND: In Mediterranean countries, the information on the prevalence of binge drinking and associated socio-demographic variables is very scarce. Moreover, there are no reported data on the amount of alcohol ingested and the type of beverage consumed during drinking episodes. This study describes the prevalence and characteristics of binge drinking in the adult population of Madrid, Spain. METHODS: Data were taken from a telephone survey conducted during the period 2000 to 2005 on 12,037 persons, representative of the population aged 18 to 64 years in the Madrid Region. Binge drinking was defined as the intake of >or=80 g of alcohol in men or >or=60 g in women, during any drinking session in the preceding 30 days. In this analysis, the threshold between moderate and heavy average weekly alcohol consumption was set at 40 g/d for men and 24 g/d for women. RESULTS: Prevalence of binge drinking was 14.4% (95% confidence interval, CI: 13.5 to 15.3%) in men and 6.5% (95% CI: 5.8 to 7.1%) in women. Prevalence was higher among persons: in the youngest age group (30.8% among men and 18.2% among women aged 18 to 24 years); having the highest educational level (14.5% in male and 9.2% in female university graduates); and with a heavy average consumption of alcohol (55.3% in men and 50.0% in women). However, 3 of 4 binge drinkers of both sexes showed a moderate average consumption. Among binge-drinkers, average monthly episodes of binge drinking were 3.2 in men and 2.6 in women, with 5.4 and 2 episodes/person/year, respectively. During each episode, a mean of 119 g of alcohol was ingested by men and 83 g by women, with spirits accounting for 72% of total alcohol intake. CONCLUSIONS: Prevalence of binge drinking is high in Madrid, particularly among younger men with higher education, and heavy average alcohol consumption. Binge drinking is characterized by frequent episodes, where large amounts of alcohol are ingested, mainly from spirits.     

Subjective measures of binge drinking and alcohol-specific adverse health outcomes: a prospective cohort study

Aim To determine the performance of subjectively defined intoxications, hangovers and alcohol‐induced pass‐outs in identifying drinkers at risk for adverse health outcomes. Design Prospective population‐based cohort study. Setting Working‐aged Finnish general population. Participants A total of 21 204 alcohol‐drinking men and women aged 20–24, 30–34, 40–44 and 50–54 years at baseline who participated in the Health and Social Support (HeSSup) postal survey in 1998. Measurements Binge drinking was measured by subjectively defined intoxications/drunkenness, hangovers and alcohol‐induced pass‐outs. Hazardous drinking was defined according to Finnish guidelines as weekly total intake of >287 g of ethanol for men, and for women > 191 g of ethanol (≥24 and ≥16 standard drinks, respectively). Study participants were followed‐up for 7 years for alcohol‐specific hospitalizations and deaths. Proportional hazard models and areas under the receiver operating characteristics curves (AUC) were used to analyse the data. Findings Of the drinkers, 6.5% exceeded the weekly limit for hazardous drinking, and 1.5% experienced the alcohol‐specific end‐point during the follow‐up. Subjective intoxications, hangovers and alcohol‐induced pass‐outs all predicted future alcohol‐specific diagnoses independently of average intake and of several other potential confounders. In identifying baseline hazardous drinking, subjective intoxications had a superior performance in relation to other subjective measures of binge drinking. In identifying future alcohol‐specific hospitalizations or death, subjective intoxications had also the best performance, but this was not significantly different from the other binge drinking measures, or average intake. Conclusions Subjectively defined intoxications, hangovers and alcohol‐induced pass‐outs are population‐level proxy measures of at‐risk drinking patterns.     

Prevalence of alcohol dependence among excessive drinkers in New Mexico

BACKGROUND: Excessive alcohol consumption claims more than 75,000 lives in the United States each year. The prevalence of alcohol dependence among excessive drinkers is not well known. METHODS: Data from the 2002 Behavioral Risk Factor Surveillance System (BRFSS) in New Mexico were used to assess the prevalence of excessive drinking, including binge drinking, heavy drinking, alcohol-impaired driving, and alcohol dependence. RESULTS: Of 4,761 respondents, 16.5% were excessive drinkers; 14.4% binge drank and 1.8% were alcohol dependent. While the rates of alcohol dependence were higher among the youngest age group, males, those with some college education, and those of race/ethnicity other than White, non-Hispanic, only differences by age were statistically significant. The prevalence of alcohol dependence was the highest among those who reported alcohol-impaired driving in the past 30 days (15.9%), and was lower among those who reported heavy drinking (13.4%) and binge drinking (8.1%). CONCLUSIONS: Although 16.5% of New Mexico adults had at least 1 type of excessive drinking, only 1.8% of all adults met the criteria for alcohol dependence. Furthermore, only a minority of those who reported binge drinking, heavy drinking, or alcohol-impaired driving met the criteria for alcohol dependence. This suggests that most alcohol problems in New Mexico are likely due to excessive drinking among persons who are not alcohol dependent. The adverse health and social consequences associated with excessive drinking are not limited to those who are alcohol dependent, but extend to a broader range of problem drinkers across the population.     

Characterizing and Reaching High-Risk Drinkers Using Audience Segmentation

Background: Market or audience segmentation is widely used in social marketing efforts to help planners identify segments of a population to target for tailored program interventions. Market‐based segments are typically defined by behaviors, attitudes, knowledge, opinions, or lifestyles. They are more helpful to health communication and marketing planning than epidemiologically defined groups because market‐based segments are similar in respect to how they behave or might react to marketing and communication efforts. However, market segmentation has rarely been used in alcohol research. As an illustration of its utility, we employed commercial data that describes the sociodemographic characteristics of high‐risk drinkers as an audience segment, including where they tend to live, lifestyles, interests, consumer behaviors, alcohol consumption behaviors, other health‐related behaviors, and cultural values. Such information can be extremely valuable in targeting and planning public health campaigns, targeted mailings, prevention interventions, and research efforts. Methods: We described the results of a segmentation analysis of those individuals who self‐reported to consume 5 or more drinks per drinking episode at least twice in the last 30 days. The study used the proprietary PRIZM? (Claritas, Inc., San Diego, CA) audience segmentation database merged with the Center for Disease Control and Prevention’s (CDC) Behavioral Risk Factor Surveillance System (BRFSS) database. The top 10 of the 66 PRIZM? audience segments for this risky drinking pattern are described. For five of these segments we provided additional in‐depth details about consumer behavior and the estimates of the market areas where these risky drinkers resided. Results: The top 10 audience segments (PRIZM clusters) most likely to engage in high‐risk drinking are described. The cluster with the highest concentration of binge‐drinking behavior is referred to as the “Cyber Millenials.” This cluster is characterized as “the nation’s tech‐savvy singles and couples living in fashionable neighborhoods on the urban fringe.” Almost 65% of Cyber Millenials households are found in the Pacific and Middle Atlantic regions of the United States. Additional consumer behaviors of the Cyber Millenials and other segments are also described. Conclusions: Audience segmentation can assist in identifying and describing target audience segments, as well as identifying places where segments congregate on‐ or offline. This information can be helpful for recruiting subjects for alcohol prevention research as well as planning health promotion campaigns. Through commercial data about high‐risk drinkers as “consumers,” planners can develop interventions that have heightened salience in terms of opportunities, perceptions, and motivations, and have better media channel identification.     

Adolescent drinking level and adult binge drinking in a national birth cohort

AIMS: To assess (i) continuities in binge drinking across adulthood and (ii) the association between adolescent drinking level and adult binge drinking. DESIGN: Population-based prospective birth cohort. SETTING: England, Scotland and Wales. PARTICIPANTS: All births during one week in March 1958 (n = 8520 in analysis). MEASUREMENTS: Alcohol consumption reported at 16, 23, 33 and 42 years. Binge drinkers were identified by dividing number of units of alcohol consumed in the last week by usual drinking frequency, with limits of >/=10 units/occasion for men and >/=7 for women. FINDINGS: Four in five cohort members drank alcohol at least twice a month. Prevalences of binge drinking at 23, 33 and 42 years among men were 37%, 28% and 31% and among women 18%, 13% and 14%. Most binge drinkers in adulthood changed drinking status during this period. Nevertheless, binge drinking at age 23 increased the odds of binge drinking at 42 years: odds ratio (OR) 2.10 (95% CI 1.85, 2.39) for men; OR 1.56 (95% CI 1.29,1.89) for women. Women who rarely or never drank aged 16 were less likely than light drinkers (0-2 units/week) to binge drink as adults, OR at 23 years 0.65 (95% CI 0.55, 0.77). Men who were heavier drinkers (>/=7 units/week) at 16 years were more likely than light drinkers to binge drink throughout adulthood; at 42 years, OR 1.64 (95% CI 1.33, 2.08). CONCLUSIONS: Binge drinking is common in British men and women throughout adulthood with continuities between the 20s and 40s. Adolescent drinking has a modest although important association with adult binge drinking.     

Measuring average alcohol consumption: the impact of including binge drinks in quantity-frequency calculations

AIMS: Average daily alcohol consumption is usually calculated based on self-reports of the quantity (number of drinks consumed per drinking-day) and frequency (number of drinking-days) of alcohol consumption within a given time period. However, this method may underestimate average daily alcohol consumption (and in turn, the prevalence of heavy drinking), because studies demonstrate that respondents do not typically include binge drinking occasions in estimates of their 'usual' or 'average' daily alcohol consumption. DESIGN: We used the Behavioral Risk Factor Surveillance System (BRFSS), an annual random-digit telephone survey of US adults aged 18 years or older, to estimate average daily alcohol consumption using standard quantity-frequency questions, and then recalculated this measure by including self-reports of binge drinking. The proportion of respondents who met a standard, sex-specific definition of heavy drinking based on average daily alcohol consumption was then assessed nationally and for each state. FINDINGS: Compared to standard quantity-frequency methods, including binge drinks in calculations of average daily alcohol consumption increased the relative prevalence of heavy drinking among all adults by 19% to 42% (depending on the method used to estimate the number of drinks per binge). Among binge drinkers, the overall prevalence of heavy drinking increased 53% relative to standard quantity-frequency methods. As a result, half of women binge drinkers and half of binge drinkers aged 55 or older met criteria for heavy drinking. CONCLUSIONS: Including binge drinks (especially the application of age- and sex-specific estimates of binge drinks) in the calculation of average daily alcohol consumption can improve the accuracy of prevalence estimates for heavy drinking among US adults, and should be considered to increase the usefulness of this measure for alcohol surveillance.
