Why do young people drink? A review of drinking motives.

This article reviews evidence of adolescent and young adult drinking motives and their relation to possible consequences over the last 15 years. To this end, a computer-assisted search of relevant articles was conducted. Results revealed that most young people reported drinking for social motives, some indicated enhancement motives, and only a few reported coping motives. Social motives appear to be associated with moderate alcohol use, enhancement with heavy drinking, and coping motives with alcohol-related problems. However, an enormous heterogeneity was found in terms of how motives were measured: 10 to 40 items were grouped into between 2 and 10 dimensions and sometimes the same items occurred under different dimensions. Future studies should therefore use well-defined, theoretically based, homogenous instruments to disentangle cultural from measurement differences across surveys.

Alcohol expectancies, drinking refusal self-efficacy and drinking behaviour in Asian and Australian students.

The effects of alcohol expectancies (AE) and drinking refusal self-efficacy (DRSE) in predicting alcohol consumption in Caucasians has been well studied. However, the role of AE and DRSE in Asian students is still not well understood. This study reported on this using Caucasian (n=98) and Asian (n=92) student samples. Participants completed the Alcohol Use Disorder Identification Test (AUDIT) to measure their hazardous alcohol consumption, and the drinking expectancy profile (DEP) to assess their alcohol related expectancies and ability to resist drinking in certain situations. Results showed that Caucasians reported significantly higher confidence, higher sexual interest, and higher tension reduction expectancies than Asians. Conversely, Asians significantly expected cognitive enhancement and negative consequences more than Caucasians. Relative to Caucasians, the Asian sample also reported that they would be more able to refuse alcohol when under social pressure. Results from regression analyses showed that for the Caucasian sample, AE, DRSE and their interactions were significant predictors of alcohol consumption. For the Asian group, the only significant effect to emerge was that DRSE was negatively related to alcohol consumption. The clinical implications of the differential pattern of results between the samples are discussed in terms of self-efficacy and negative consequences of alcohol consumption, especially when dealing with university aged individuals.

Do good things come to those who drink? A longitudinal investigation of drinking expectancies and hazardous alcohol use in female college athletes.

PURPOSE: To prospectively examine the link between positive and negative drinking expectancies and hazardous alcohol use, and to explore the reciprocal associations between expectancies and hazardous use among female college athletes. METHOD: Participants were part of a larger (n = 189), ongoing longitudinal study on female athletes' socialization experiences and health behaviors from an all-women's college in the Northeastern United States. The sample for the present study were 85 college-aged (17-22 years) female students (Mean age = 19.6) who indicated alcohol use in the past year and provided data at both time points (baseline and one year later). Respondents completed self-report questionnaires on their age, hazardous alcohol use, and expectations about the effects of drinking. RESULTS: Logistic regression analyses showed that positive drinking expectancies predicted increased odds of hazardous alcohol use at baseline and one year later (even after controlling for baseline hazardous use). Positive expectancies accounted for a higher proportion of variance in predicting increased odds of hazardous alcohol use at both time points than did negative expectancies. Bivariate correlational analyses examining the bi-directional associations between expectancies and hazardous alcohol use also revealed some indication that positive expectancies were associated with hazardous alcohol use rather than vice-versa. No such relations emerged for negative expectancies. CONCLUSIONS: Findings shed light on the utility of positive expectancies in predicting concurrent and subsequent hazardous alcohol use among female student-athletes. Future research directions and potential implications for prevention efforts are discussed.

An inter-gender effect on ethanol drinking in rats: proximal females increase ethanol drinking in males.

Three groups of male Long-Evans hooded rats were assessed for effects of social opportunity on drinking of ethanol or water. The ethanol/female group received intermittent presentations of a sipper containing ethanol that was followed by 15 s of social interaction opportunity with a female rat. The ethanol/male group received similar training except the social interaction opportunity was with a male rat. The water/female group received training similar to the ethanol/female group except that the sipper contained water. For the ethanol groups, the concentration of ethanol [3%, 4%, 6%, 8% and 10% (vol/vol)] in the sipper was increased across sessions. With 10% ethanol in the sipper, social opportunity with females induced more drinking and ethanol intake than did social opportunity with males. Social opportunity with females induced more intake of ethanol than water. Post-session plasma samples revealed social opportunity with females induced higher corticosterone and testosterone levels than did social opportunity with males, irrespective of the sipper fluid. This study documents, for the first time, an inter-gender effect on ethanol drinking in rats.

Gender stereotypes and drinking cognitions as indicators of moderate and high risk drinking among young women and men.

The study examined differences in gender stereotypes, restrained drinking and self-efficacy for alcohol refusal between moderate and high risk drinkers among a university sample of 301 women and 118 men. Both female and male high risk drinkers displayed a response conflict, typified by high scores on restrained drinking but low scores on self-efficacy. This pattern of response conflict was more pronounced for high risk drinking women, who also identified poorly with feminine traits (e.g. 'nurturing', 'love children', 'appreciative'). The findings are discussed in relation to society's double standard that accepts intoxication in men but condemns it in women.

Hard liquor drinking is associated with higher risk of cancer of the oral cavity and pharynx than wine drinking. A case-control study in Uruguay.

In order to examine the relationship between pure drinkers of alcoholic beverages and cancer of the oral cavity and pharynx, a case-control study was conducted in Uruguay between 1992 and 1996. 471 cases and 471 controls, admitted for diagnosis or treatment in the four major hospitals in Montevideo, were considered eligible for the study. Pure hard liquor drinking was associated with an increased risk of 3.6 (95% confidence limit (CL) 2.1-6.2), whereas pure wine drinking showed an odds ratio (OR) of 2.1 (95% CL 1.3-3.3). When pure hard liquor drinkers were compared with pure wine drinkers, the OR for pure liquor drinkers was 1.7 (95% CL 1.1-2.7). Furthermore, the risk associated with pure hard liquor drinking was analysed by subsite, and the highest odds ratios were observed for oral cavity cancer. Further studies should be carried out in order to replicate these findings in other populations.

More Canadian students drink but American students drink more: comparing college alcohol use in two countries.

AIMS: To compare alcohol use among US and Canadian college students. DESIGN: Results of the 1999 College Alcohol Study and the 1998 Canadian Campus Survey are compared. SETTING: One hundred and nineteen nationally representative US 4-year colleges and universities in 40 states and 16 nationally representative Canadian 4-year universities. PARTICIPANTS: Randomly selected students under 25 years (12 344 US and 6729 Canadian). MEASUREMENTS: Self-reports of alcohol use and heavy alcohol use. FINDINGS: The prevalence of life-time and past year alcohol use is significantly higher among Canadian students than US students (92% versus 86%, 87% versus 81%). The prevalence of heavy alcohol use (typically consuming five or more drinks in a row for males/four or more for females) among past-year and past-week drinkers is significantly higher among US students than Canadian students (41% versus 35%, 54% versus 42%). In both countries older [corrected] students and students living at home with their parents are less likely to be heavy drinkers; students who report first drunkenness before the age of 16 are more likely to be heavy drinkers in college. CONCLUSION: Programs aimed at students' heavy alcohol use should target freshman at entry or earlier. Since students living with their parents are less likely to be heavy drinkers, parents may play a potentially important role in prevention efforts. The patterns of drinking in both countries may be influenced by the legal minimum drinking age. However, the relationship is complex and must be viewed in the context of other variables such as chronological age.

Drinking and drinking patterns and health status in the general population of five areas of China.

AIMS: To understand drinking patterns, health status related to drinking and the level of unrecorded alcoholic beverage consumption for the general population living in five areas of China in 2001. METHODS: By cluster sampling, 24992 community residents aged 15 years or older were interviewed by trained psychiatrists using structured questionnaires provided by WHO. RESULTS: The 1-year drinking rate was 59.0%, and the point prevalence rate of dependence was 3.8%. The average annual consumption of pure alcohol was 4.47 l. The 1-year morbidity from gastritis/ulcer in the whole sample was 7.9%, which associated nonlinearly to alcohol intake, and heart disease and cerebral infarction/cerebral haemorrhage showed V-shaped curve relationships. CONCLUSIONS: The rate of alcohol use was higher in men than in women, and the annual alcohol consumption per capita was higher than that in the 1990s in the selected areas. Alcohol consumption plays a role in the development of alcohol-related physical diseases.

Effects of neuropeptide Y on sucrose and ethanol intake and on anxiety-like behavior in high alcohol drinking (HAD) and low alcohol drinking (LAD) rats.

BACKGROUND: In a previous study, neuropeptide Y (NPY) administered into the lateral ventricles decreased ethanol intake in alcohol-preferring (P) rats but not in alcohol-nonpreferring (NP) or unselected Wistar rats. The purpose of the present investigation is to extend these findings in selectively-bred high-alcohol-drinking (HAD)1 and low-alcohol-drinking (LAD)1 rats by examining the effects of intracerebroventricularly administered NPY on the elevated plus maze test of anxiety and on ethanol and sucrose intake. METHODS: Female HAD1 and LAD1 rats were surgically implanted with cannula into the lateral ventricle. Following recovery, a test of anxiety was conducted in which the rats (n = 12-13/group) received either artificial cerebrospinal fluid (aCSF) or NPY (10 microg) 10 min prior to a 5-min test on an elevated plus maze. Following anxiety testing, 11 HAD and 11 LAD rats were trained to self-administer ethanol (8% w/v), and 5 HAD and 8 LAD rats were trained to self-administer sucrose (2.5%) during daily 2-hr sessions. A within-subject design was used in which the rats were pretreated once a week with aCSF, 5 microg NPY, or 10 microg NPY prior to the drinking sessions. RESULTS: HAD and LAD rats treated with aCSF did not differ in time spent in open arms of the plus maze. NPY increased time spent on the open arms to similar degrees in both rat lines. HAD rats consumed more ethanol and sucrose than LAD rats. NPY increased sucrose intake in both rat lines. However, the same doses of NPY reduced ethanol intake in HAD but not in LAD rats. CONCLUSION: The plus maze results indicated that selective breeding for high and low alcohol preference in the HAD1 and LAD1 rats, respectively, did not yield differences in anxiety-like behavior and in response to the anxiolytic effects of NPY. The increases in sucrose intake were consistent with the known orexigenic effects of NPY. The decreased ethanol intake following NPY administration in HAD rats was similar to previous observations with P rats and is consistent with the hypothesis that ethanol intake and NPY activity may be inversely related.

Effects of heavy drinking, binge drinking, and family history of alcoholism on regional brain metabolites.

BACKGROUND: The main goals are to investigate the effects of chronic active heavy drinking on N-acetylaspartate (NAA) and other metabolites throughout the brain and to determine whether they are affected by family history (FH) of alcoholism and long-term drinking pattern. METHODS: Forty-six chronic heavy drinkers (HD) and 52 light drinkers (LD) were recruited from the community and compared on measures of regional brain structure using magnetic resonance imaging and measures of common brain metabolites in gray matter (GM) and white matter (WM) of the major lobes, subcortical nuclei, brainstem, and cerebellum using short-echo time magnetic resonance spectroscopic imaging. Regional atrophy-corrected levels of NAA, myoinositol (mI), creatine, and choline-containing metabolites were compared as a function of group, FH of alcoholism, and bingeing. RESULTS: Frontal WM NAA was lower in FH-negative HD than FH-positive HD and tended to be lower in women than men. Creatine-containing metabolites in parietal GM were higher in HD than LD. FH-negative compared with FH-positive HD also had more mI in the brainstem and tended to have lower NAA and more mI in frontal GM. Although parietal GM NAA was not significantly lower in HD than LD, it was lower in non-binge drinkers than bingers. Frontal WM NAA was lower in HD than LD, with the difference driven by a small number of women, FH-negative HD, and older age. Lower frontal WM NAA in HD was associated with lower executive and working memory functions and with lower P3b amplitudes at frontal electrodes. CONCLUSIONS: Community-dwelling HD who are not in alcoholism treatment have brain metabolite changes that are associated with lower brain function and are likely of behavioral significance. Age, FH, and binge drinking modulate brain metabolite abnormalities. Metabolite changes in active HD are less pronounced and present with a different spatial and metabolite pattern than reported in abstinent alcoholics.

Offspring of parents with drinking problems: drinking and drug-taking as young adults.

One hundred and seventy 16 to 35 year-old offspring of parents with drinking problems and 80 comparison young adults were recruited from a variety of clinical and community sources. Each was interviewed at length using a semi-structured interview and 86% were re-interviewed one year later. No between-group differences were found in current quantity of alcohol consumption nor in percentages who had ever used or were currently using illicit or prescribed drugs. However, larger numbers of offspring had commenced alcohol use in their early teens and had used other drugs in their later teens, and more offspring than comparisons were currently using alcohol in a risky way, more were using illicit drugs more than occasionally, and more were heavy smokers. These differences were not great, and gender and source of recruitment (clinical versus community) were equally important predictor variables. Analyses conducted within the offspring group offered no support for hypotheses linking adulthood risk with years of exposure, severity of childhood effects and experiences, maternal as opposed to paternal problems, or problems in the same sex parent. However, some support was found for the importance of having had two parents with drinking problems and having had a drinking parent who often drank at home.

High risk drinking settings: the association of serving and promotional practices with harmful drinking.

A household survey of 1160 Western Australian adults was used as a basis for exploring drinkers' reports about the settings in which they drank alcohol and their experiences of alcohol related harm. Of the 873 drinkers identified, 7.9% had experienced some form of acute alcohol related harm over the previous 3 months. Violent incidents were the most common of these and drink-driving offences the least. Such harm was significantly more likely among drinkers who variously drank 'heavily', were male, single, under 25 years of age and/or who drank on licensed premises. Regression analyses revealed that even when demographic characteristics of the drinkers were controlled for licensed premises were significantly more likely to be the settings used prior to harm occurring. Bar staff continuing to serve 'obviously intoxicated' customers was the most powerful predictor of harm. Premises which offered discounted drinks or permitted crowding also tended to be those where intoxication was permitted but these variables were not directly associated with an increased risk of harm. These findings lend further weight to the view that prevention efforts should focus on licensed drinking environments and, in particular, the practice of continuing to serve obviously intoxicated customers.

Drinking norms versus drinking behavior.

Data from 1002 households indicated that contextual factors (group size, subsequent activity) and individual difference factors (sex, extroversion, drinking frequency) differentially influenced consumption and normative ratings. These findings suggest that contextual cues serve as determinants of drinking norms and that drinking behavior reflects individual variation in sensitivity to these cues.

Taste reactivity in high alcohol drinking and low alcohol drinking rats.

High alcohol drinking (HAD) and low alcohol drinking (LAD) rats were tested, in three exposures, for taste reactivity to five concentrations of alcohol (5%, 10%, 20%, 30%, and 40%, v/v), water, and one concentration each of sucrose and quinine. Of the three reactivity exposures, one was done before a 3-week period of continuous access to water and 10% alcohol, the second test was done immediately after the consumption period, and the final reactivity test was done after 1 month of alcohol abstinence. The results showed that the groups did not differ in reactivity on the initial test. After the consumption tests (when the HAD rats consumed significantly more alcohol than the LAD rats), differences in reactivity were found: HAD rats produced significantly more ingestive responses (which promote consumption) and significantly fewer aversive responses (which facilitate fluid rejection) than LAD rats. These differences were maintained even after 1 month of alcohol abstinence. The present data replicate an earlier experiment with alcohol-preferring (P) rats and alcohol-non-preferring (NP) rats, and indicate that the selective breeding process does not produce differences in the innate perception of the taste of alcohol. However, after experience with drinking alcohol, rats selectively bred for high alcohol consumption exhibit a palatability shift reflected by high ingestive responding and little or no aversive responding. Such a shift would clearly contribute to the maintenance of high levels of alcohol consumption.

Drink composition, voluntary drinking, and fluid balance in exercising, trained, heat-acclimatized boys.

This study examined the effects of beverage composition on the voluntary drinking pattern, body fluid balance, and thermoregulation of heat-acclimatized trained boys exercising intermittently in outdoor conditions (wet bulb globe temperature 30.4 +/- 1.0 degreesC). Twelve boys (age 13.4 +/- 0.4 yr) performed two 3-h sessions, each consisting of four 20-min cycling bouts at 60% maximal aerobic power alternating with 25-min rest. One of two beverages was assigned: unflavored water (W) or flavored water plus 6% carbohydrate and 18 mmol/l Na (CNa). Drinking was ad libitum. Total intake was higher (P < 0.05) during CNa (1,943 +/- 190 g) compared with W (1,470 +/- 143 g). Euhydration was maintained with CNa (+0.18% body wt), but a mild dehydration resulted with W (-0.94% body wt; P < 0.05). Sweat loss, much higher than previously published for children of similar age, was similar between conditions (CNa = 1,644.7 +/- 117.5; W = 1,750.2 +/- 152.7 g). The increase in rectal temperature (CNa = 0.86 +/- 0.3; W = 0.76 +/- 0.1 degreesC), heart rate, and all perceptual variables did not differ between conditions. In conclusion, a flavored carbohydrate-electrolyte drink prevents voluntary dehydration in trained heat-acclimatized boys exercising in a tropical climate despite their large sweat losses. Because hydration changes were minor, the thermoregulatory strain observed was similar between conditions.

Drinking patterns and drinking problems of college students.

Compared with the findings of previous studies, a recent survey of students at 13 U.S. colleges found that more women are drinking, fewer Black men are heavy drinkers, there are fewer differences in the drinking patterns of freshmen and seniors, and there has been no increase in the incidence of drinking-related problems.

Drinking, drinking styles and drug use in children of alcoholics, depressives and controls.

Adolescent children of alcoholic, depressive and normal control fathers were assessed with a variety of alcohol and drug use measures. Children of alcoholics were quite similar to the other two groups with regard to alcohol consumption, reasons for drinking, attitudes toward temperate and intemperate use of alcohol, and the typical drinking context. However, children of alcoholics, both male and female, were more likely to report drug use than children of depressives or children of normal controls. These findings suggest that although children of alcoholics are at risk for the development of alcoholism, deviant drinking practices may not be discernible in adolescence.

Problem drinking in a general practice population: the construction of an interval scale for severity of problem drinking.

The main aim of this article is to describe the construction of an interval scale measuring the severity of problem drinking among patients of general practitioners. A questionnaire, including the existing screening instruments CAGE, SMAST, a shortened version of the SAAST and some additional items on alcohol-related problems, was given to three categories of patients: those who, according to the general practitioner, were not problem drinkers (Group 1), those who perhaps were (Group 2) and those who were known by the general practitioner to be problem drinkers (Group 3). According to the Classical Test Theory, the three existing screening instruments and the combination of all questions form a reliable scale. Advanced scaling techniques were applied to select the best items for the construction of an interval scale. These analyses showed that 18 of the 28 questions in the complete screening list fitted in a unidimensional Rasch scale. These questions can be used to estimate the severity of problem drinking. For research purposes an interval scale is attractive, since no information is lost by dichotomization. Such a scale enables the level of problem drinking to be specified at which correlations with other factors, whether as a cause or as an effect, can be found. The scale could also be a help to general practitioners for referral decisions. In more specialized settings it can be used to assign patients to various treatments.
