Differential alcohol use patterns and personality traits among three Alcoholics Anonymous attendance level groups: further considerations of the affiliation profile.

The present study was designed to identify personality and drinking behavior correlates associated with membership in Alcoholics Anonymous (A.A.). Affiliation profiles were developed on the basis of frequency of A.A. attendance; subtypes were defined as non, low, and high affiliates, respectively. An initial canonical correlation analysis assessed the amount of common variance between personality and drinking characteristics. Subsequent discriminant function analyses on the second-order scales of the drinking and personality variables sets identified those variables differentiating the A.A. affiliated groups. High levels of affiliation were associated with a greater degree of anxiety, a tendency to be more affected by feelings rather than intellect, and more deterioration in the physical, exhibited significant differences in perceived benefits, style, and consequences of alcohol usage. The potential therapeutic utility of A.A. affiliation profiles was discussed.

Stable preference for high ethanol concentrations after ethanol deprivation in Sardinian alcohol-preferring (sP) rats.

Results of a recent study have demonstrated that exposure to multiple ethanol concentrations and repeated ethanol deprivation periods in Indiana ethanol-preferring (P) rats resulted in the development of an alcohol deprivation effect (ADE; the temporary increase in voluntary ethanol intake after a period of deprivation from ethanol) characterized by consumption of intoxicating amounts of ethanol. The current study was designed to possibly extend these results to Sardinian alcohol-preferring (sP) rats, generated with the same selective program previously used for P rats. To this aim, ethanol-naive sP rats were exposed initially to the home cage four-bottle choice [10%, 20%, and 30% (vol./vol.) ethanol solutions and water] for eight consecutive weeks. Subsequently, rats were divided into two groups: The first group had continuous access to the four-bottle regimen (nondeprived rats), and the second group was exposed to five cycles of 14-day periods of deprivation from ethanol and 14-day periods of reexposure to the four-bottle regimen. An ADE developed after each deprivation period. However, the extra intake of ethanol was limited to the first hour of each reaccess period. Magnitude of ADE did not change with repeated periods of deprivation. However, a shift in preference toward the two highest concentrations of ethanol solutions was evident from the first reexposure to ethanol and was maintained throughout the study. These results provide further evidence on the heterogeneity of ethanol-drinking behavior among rat lines selectively bred for high ethanol preference and consumption.

Alcohol input and creative output.

Is alcohol use a help or a hindrance for creativity? And, conversely, what effect does creative activity have on alcohol use? In order to answer these questions, relevant information was obtained from the biographies of 34 well known, heavy drinking, 20th century writers, artists or composers/performers. Analysis of this information yielded a number of interesting findings. Alcohol use proved detrimental to productivity in over 75% of the sample, especially in the latter phases of their drinking careers. However, it appeared to provide direct benefit for about 9% of the sample, indirect benefit for 50% and no appreciable effect for 40% at different times in their lives. Creative activity, conversely, can also affect drinking behavior, leading, for instance, to increased alcohol consumption in over 30% of the sample. Because of the complexities of this relationship, no simplistic conclusions are possible.

Tobacco and alcohol use in lung transplant candidates and recipients.

Tobacco and alcohol use among lung transplant candidates and recipients is unknown. Our first goal was to describe tobacco and alcohol use before and after lung transplant in patients with cystic fibrosis (CF) and other pulmonary diseases (non-CF). Our second goal was to determine whether demographic variables, depression, anxiety and social support predicted tobacco and alcohol use. Self-report data from transplant candidates and recipients, and transplant nurse coordinator ratings of post-transplant smoking and drinking were utilized. Data from two samples were analyzed. Sample 1 comprised 219 patients being evaluated for lung transplant, and sample 2 comprised 45 transplant recipients who were 1-7 yrs post-transplant. The results from analyzing sample 1 indicated that 72% of non-CF patients and 16% of CF patients had a history of smoking cigarettes, and the majority of patients in both groups had consumed alcohol in the past. For CF patients, past smoking was related to higher depression scores, and past drinking was related to higher education and lower social support. For non-CF patients, a history of smoking was associated with being Caucasian and older. For CF patients, a history of drinking was associated with being older and less depressed, and for non-CF patients a history of drinking was associated with higher education and lower social support. Post-transplant 100% of recipients reported abstinence from tobacco, and over 60% reported abstinence from alcohol. Transplant coordinator ratings corroborated that no transplant recipients were using tobacco products or consuming alcohol in an excessive or problematic manner. For both groups, consuming alcohol after transplant was related to lower levels of social support. In conclusion, lung recipients remain abstinent from tobacco, and although over 30% of patients consume alcohol after transplant, it is not at problematic levels. Smoking and drinking behaviors were related to demographic variables, depression, and low social support.

Drinking patterns and drinking problems among Asian-Americans and Pacific Islanders.

Researchers are increasingly investigating the drinking behavior and associated consequences among Asian-Americans and Pacific Islanders (APIs) in the United States. Among adolescents, APIs generally have lower rates of alcohol consumption and appear to be at lower risk for alcohol abuse compared with other ethnic groups. Similarly, the rates of drinking and heavy drinking have been found to be lower among API college students than among other ethnic groups. Among adult Asian-Americans, Japanese-Americans have the highest and Chinese-Americans have the lowest lifetime prevalence of drinking and heavy drinking. Southeast Asians (e.g., Vietnamese) living in the United States appear to be at high risk for heavy drinking. Numerous factors help determine the drinking patterns of APIs, including their economic status, educational attainment, and degree of acculturation as well as genetic and environmental factors, such as drinking norms and alcohol availability.

Dental pathology and alcohol-related indicators in an outpatient clinic sample.

A relationship between alcoholism and dental pathology (particularly missing teeth), has been reported in studies of male, inpatient alcoholics. The present exploratory study was undertaken to assess how readily these findings can be generalized to an unselected sample of male and female dental patients. Data on drinking behavior, alcohol-related problems, and risk factors for alcoholism were obtained through an interview and questionnaire. A dental chart review provided measures of dental pathology. The results showed that measures of dental pathology (including tooth loss, carious teeth, and periodontal disease) correlated significantly with alcohol-related indicators. The associations were more evident for males than for females, which is consistent with some studies of alcohol-related medical consequences. The results suggest that further analytic studies of alcohol consumption and dental pathology are warranted. Because the relationship between tooth loss and harmful drinking was clearest among males with a history of conduct problems, subsequent research would benefit from a focus on this high-risk group.

Subgroup differences in drinking patterns among black and white men: results from a national survey.

Despite major increases in alcohol-related health problems and indications of shifts in the cultural role of alcoholic beverages among U.S. blacks, few studies have examined drinking patterns in this population. To address gaps in the literature, data from a 1984 national survey were used to compare drinking patterns and their sociocultural correlates among male, black (n = 723) and male, white (n = 743) Americans. Findings from the survey indicate that, at the aggregate level, black and white men exhibit very similar drinking patterns. The proportion of abstainers, infrequent, frequent and heavier drinkers is very similar for the two groups of men. However, major black-white differences occur when the relationship between drinking rates and major social characteristics is considered. Bivariate tables suggest that frequent heavier drinking among whites is associated with youthfulness, high-income status and residing in "wetter" areas, whereas among blacks these patterns are reversed or absent. Log-linear analysis confirmed some of these findings. When drinking behavior was modeled with respect to race, age, income and region, race emerged as an independent predictor and the effects of age and income varied by race. When the two groups of men were analyzed separately, age and region were the only significant determinants of heavier drinking among whites. Among blacks, income and age emerged as significant variables and the influence of age differed from the findings for whites. The results suggest that there may be important differences in the cultural environments of drinking in black and white men.

Regional CNS densities of serotonin 1A and dopamine D2 receptors in periadolescent alcohol-preferring P and alcohol-nonpreferring NP rat pups.

The objective of the present study was to use quantitative autoradiography to determine binding densities of serotonin(1A) (5-HT(1A)) and dopamine (DA) D(2) receptors in alcohol-naive periadolescent P and NP rat pups. P (n=8) and NP (n=7) rat pups, 25 days of age, from different litters were used. Coronal brain sections were incubated with 2 nM [3H]8-OH-DPAT or 20 nM [3H]sulpiride for 5-HT(1A) or D(2) binding, respectively. Approximately 15-40% higher densities of [3H]8-OH-DPAT binding were observed in the anterior cortical regions of the periadolescent P rat compared with NP rat pups. Similar differences were also observed in posterior cortical regions with P rats having 25-40% higher [3H]8-OH-DPAT binding than NP rats. [3H]8-OH-DPAT binding was approximately 10-20% higher in posterior hippocampal regions of the P rat pups compared with the NP line. [3H]sulpiride binding was significantly different only in the ventral tegmental area (VTA), where binding was approximately 20% lower in the periadolescent P rats compared with the NP rat pups. Overall, these results are very similar to findings observed in adult alcohol-naive P and NP rats, and suggest that the innate differences in the neural systems implicated in high alcohol drinking behaviors may already be established in the periadolescent animal.

Alcohol use among pregnant African American women: ecological considerations.

Alcohol use across pregnancy causes growth and other abnormalities in the offspring. Confirmation of pregnancy leads some women to discontinue alcohol use and other women to continue use. The study discussed in this article assessed alcohol use at the first and third trimesters and at delivery for 393 pregnant African American women in an urban area. At the first trimester, 118 women were moderate to heavy drinkers (one or more drinks per day), compared with 38 women who were at delivery. Socioenvironmental and psychological differences were identified for both women who reduced consumption and women who continued. An understanding of continued drinkers' vulnerability to factors that influence their drinking behaviors demands the development of appropriate, early, and effective intervention strategies. Social welfare implications are discussed.

Diagnosis of chronic alcoholism--classificatory problems.

Since Magnus Huss introduced the diagnosis of 'chronic alcoholism' into medical literature in 1849, two unsolved problems concerning classification have remained: (1) Differentiation between problem drinkers and chronic alcoholics fluctuates, whereby the cut point of differentiation between abuse and addiction remains differently defined by different authors. Some authors view alcohol-induced damage as a building-stone of diagnosis of chronic alcoholism whereas other authors define these damages as illnesses developed as a consequence of chronic alcohol intake. This fact is also mirrored in the different definitions of chronic alcoholism by different classification systems, like ICD-9, DMS-III or DMS-III-R. Valid and reliable questionnaires, like the Munich Alcoholism Test or the Problem Drinking Scale did not succeed in solving this problem of definition, either. (2) The fact that chronic alcoholics are sick--in the sense of a biological-medical approach--is undoubted. Our research group was able to prove that chronic alcoholic patients metabolize methanol in a different way from that of healthy persons. The biological, sociological and psychopathological heterogeneity of this illness has been stressed for more than a century. A prospective long-term study carried out over 4-7 years has led to the development of a new typology in chronic alcoholism that is able to differentiate subgroups of chronic alcoholic patients cross-sectionally in a clinical, biochemical and neurophysiological way. Diagnosis according to this typology qualitatively differentiates patients in many spheres other than drinking behavior. These subgroups also require correspondingly modified therapeutic strategies.

Prediction of readmission in a cohort of alcoholics: a 2-year follow-up.

A cohort of 1,192 first admissions to metropolitan public alcohol treatment programs was examined after 2 years. With the sample sub-divided by number of readmissions, discriminant analysis based on demographic data, social history, and current drinking behavior provided only modest prediction of group membership (k = .46), but may be sufficient to provide an alerting function for recidivism.

[Effects of intraperitoneally administered spermine on ingestive behavior, serum glucose and free fatty acids concentrations in rats (author's transl)].

The intraperitoneal administration of spermine (SPM) produced a dual-phasic feeding suppression. The first suppression appeared immediately after the administration and disappeared on the 2nd day. The next suppression was observed on the 3rd day and continued for 2-4 days. The 50% dose which induced suppression on the 3rd day was 64.9 (60.9-69.2) mumol/kg. Drinking behavior was also suppressed on the 1st day, but was facilitated on the 2nd day and lasted for 4-5 days. Serum glucose and free fatty acids concentrations increased after the administration of SPM (80 mumol/kg). Their maximal values obtained at 3 hours after the dosing were 116% and 156% of the control values, respectively. These increases in both substances were not observed in the adrenal-demedullated rats. The same dose of SPM enhanced serum glutamic oxaloacetic transaminase and glutamic pyruvic transaminase activities. The maximal values obtained at 2 hours after the dosing were 264% and 142% of the control values, respectively. On the contrary, serum cholinesterase activity decreased to 44% of the control value at the same hour. These variations of the enzyme activities disappeared at 3 hour, but were again observed between the 1st and 4th days. The results suggest that SPM releases catecholamines from the adrenal medulla, and exerts a toxic action on the liver. The anorexia induced by SPM may be due to these actions on the viscera.

Regional CNS densities of serotonin and dopamine receptors in high alcohol-drinking (HAD) and low alcohol-drinking (LAD) rats.

The densities of subtypes of serotonin (5-HT) and dopamine (DA) receptors were determined in the CNS of male alcohol-naive HAD and LAD lines of rats. Autoradiographic studies were undertaken to measure the densities of (a) 5-HT1A sites labelled with 2 nM [3H]8-OH DPAT, (b) 5-HT2A sites labelled with 2 nM [3H] ketanserin, (c) D1 sites labelled with 1 nM [3H]SCH23390, and (d) D2 sites labelled with 20 nM [3H]sulpiride. Membrane binding, using tissue combined from the olfactory bulb, olfactory tubercle, and nucleus accumbens, was carried out to determine Kd and Bmax values for the binding of 0.25-8.0 nM [3H]7-OH DPAT to D3 sites. Among the 14 regions measured for densities of 5-HT1A sites, no interline differences were found in the cerebral cortical regions or in the septal nuclei; however, within the hippocampus, 15-20% lower binding of [3H]8-OH DPAT was observed in the posterior dorsal CA3 and dentate gyrus of the HAD line. There were no interline differences in any of the 10 regions examined for [3H]ketanserin binding to 5-HT2A sites, or in the densities of D1 and D2 sites in the mesolimbic and nigrostriatal DA systems, except for a 35% higher density of D2 sites in the substantia nigra pars compacta of the HAD line. There were no interline differences in the Kd or Bmax values for [3H]7-OH DPAT binding to D3 sites. Overall, these results indicate that no marked interline differences are evident in the densities of 5-HT1A, 5-HT2A, D1, D2, and D3 receptors within the mesolimbic system that could be associated with the disparate alcohol drinking behaviors of the HAD and LAD rats.

Gender differences in animal studies. Implications for the study of human alcoholism.

The reasons for gender differences in alcohol intake, responses to alcohol, and consequences of alcohol abuse in humans and in animals are poorly understood. Animal models for the study of alcoholism have been focused primarily on the study of male rodents, although researchers have observed that female rodents drink more alcohol than males and have sex-related differences in drinking patterns and responses to alcohol. In humans, the difference between the sexes is the opposite of rodents, with males drinking more than females. These results suggest differences between the sexes and differences between humans and rodents in drinking behavior and responses to alcohol which may be based on a complex interaction of social, genetic, hormonal, neurobiologic, and environmental factors. Four new studies are introduced to identify sex-distinct genetic influences in alcohol-related phenotypes, sex-based differences in behavioral responses to alcohol, sex differences in responses of brain reward systems to alcohol, and interactions of the anxiolytic effects of alcohol with steroids and the estrous cycle.

Effects of ethanol on the levels of brain 6R-L-erythro-5, 6, 7, 8-tetrahydrobiopterin in the inbred strains of mice. DBA/2J, C3H/HeJ and C57BL/6J with different alcohol preferences.

6R-L-erythro-5, 6, 7, 8-tetrahydrobiopterin (6R-BH4) is a coenzyme for tyrosine, tryptophan and phenylalanine hydroxylases, the former two of which are the initial and the rate-limiting enzymes in the biosynthesis of the catecholamines and serotonin, respectively. The present study was designed to determine the changes in concentrations of 6R-BH4 in striatum and midbrain of the inbred strains of mice, DBA/2J, C3H/HeJ and C57BL/6J, with different genetically determined alcohol preferences, following the injection of ethanol (EtOH). The intraperitoneal administration of EtOH (0, 1, 2 and 4 g/kg) significantly and dose-dependently reduced the levels of striatal and midbrain 6R-BH4 in DBA/2J mice with the lowest alcohol preference, and EtOH (4 g/kg, i.p.) reduced the level of striatal 6R-BH4 in C3H/HeJ with medium alcohol preference. Following the administration of EtOH (4 g/kg, i.p.), brain 6R-BH4 levels in C57BL/6J mice with high alcohol preference were lowered compared with the control group, but the difference did not reach statistic significance. EtOH has a tendency to reduce the brain 6R-BH4 levels in mice with lower alcohol preference or higher sensitivity to EtOH. Based on these findings, it was proposed that differences in alcohol drinking behavior in the inbred strains of mice was influenced by brain 6R-BH4.

Weaning in the Norway rat: relation between suckling and milk, and suckling and independent ingestion.

We examined in rat pups the relation between the decline of suckling and the emergence of independent ingestion, and the role of milk delivery conditional on nipple attachment in the maintenance of suckling. Fifteen-day-old litters were reared for either 5 or 10 days, and 20-day-old litters for 5 days by either a thelectomized (no nipples), ligated (nipples but no milk), or intact (nipples and milk) dam. Pups' food and water intakes were monitored daily, and their suckling, feeding, and drinking behaviors were videorecorded for 24 hr in the presence of their foster dam (Day 19 or 24) and for 24 hr in the presence of an intact, lactating dam (Day 20 or 25). There were no differences between treatment conditions with respect to either the onset or rate of increase of independent feeding or drinking. Pups reared by a thelectomized dam for 10 days displayed a pronounced, lasting depression of suckling. Twenty-five-day-old pups reared by a ligated dam displayed suckling levels comparable to those of control pups; in the presence of the ligated dam, however, their tendency to attach to a nipple was notably reduced. The implications of the findings for our understanding of the weaning process are discussed.

Comparison of voluntary ethanol intake by two pairs of rat lines used as genetic models of anxiety.

The relationship between anxiety-related behaviors and voluntary ethanol intake was examined in two pairs of rat lines by the oral ethanol self-administration procedure. Floripa high (H) and low (L) rats selectively bred for contrasting anxiety responses in the open-field test, and two inbred strains, spontaneously hypertensive rats (SHR) and Lewis rats which are known to differ significantly when submitted to several behavioral tests of anxiety/emotionality, were used (9-10 animals/line/sex). No differences in the choice of ethanol solutions (2%, days 1-4, and 4%, days 5-8, respectively) in a 2-bottle paradigm were detected between Floripa H and L rats (1.94 +/- 0.37 vs 1.61 +/- 0.37 g/kg for ethanol intake on day 8 by the Floripa H and L rat lines, respectively). Contrary to expectations, the less anxious SHR rats consumed significantly more ethanol than Lewis rats (respective intake of 2.30 +/- 0.45 and 0.72 +/- 0.33 g/kg on day 8) which are known to be both addiction-prone and highly anxious. Regardless of strain, female rats consumed more ethanol than males (approximately 46%). The results showed no relationship between high anxiety and voluntary intake of ethanol for Floripa H and L rats. A negative association between these two variables, however, was found for SHR and Lewis rat strains. Data from the literature regarding the association between anxiety and alcohol intake in animal models are not conclusive, but the present results indicate that factors other than increased inborn anxiety probably lead to the individual differences in ethanol drinking behavior.

The reliability and validity of the self-reported drinking measures in the Army's Health Risk Appraisal survey.

BACKGROUND: The reliability and validity of self-reported drinking behaviors from the Army Health Risk Appraisal (HRA) survey are unknown. METHODS: We compared demographics and health experiences of those who completed the HRA with those who did not (1991-1998). We also evaluated the reliability and validity of eight HRA alcohol-related items, including the CAGE, weekly drinking quantity, and drinking and driving measures. We used Cohen's kappa and Pearson's r to assess reliability and convergent validity. To assess criterion (predictive) validity, we used proportional hazards and logistical regression models predicting alcohol-related hospitalizations and alcohol-related separations from the Army, respectively. RESULTS: A total of 404,966 soldiers completed an HRA. No particular demographic group seems to be over- or underrepresented. Although few respondents skipped alcohol items, those who did tended to be older and of minority race. The alcohol items demonstrate a reasonable degree of reliability, with Cronbach's alpha = 0.69 and test-retest reliability associations in the 0.75-0.80 range for most items over 2- to 30-day interims between surveys. The alcohol measures showed good criterion-related validity: those consuming more than 21 drinks per week were at 6 times the risk for subsequent alcohol-related hospitalization versus those who abstained from drinking (hazard ratio, 6.36; 95% confidence interval=5.79, 6.99). Those who said their friends worried about their drinking were almost 5 times more likely to be discharged due to alcoholism (risk ratio, 4.9; 95% confidence interval=4.00, 6.04) and 6 times more likely to experience an alcohol-related hospitalization (hazard ratio, 6.24; 95% confidence interval=5.74, 6.77). CONCLUSIONS: The Army's HRA alcohol items seem to elicit reliable and valid responses. Because HRAs contain identifiers, alcohol use can be linked with subsequent health and occupational outcomes, making the HRA a useful epidemiological research tool. Associations between perceived peer opinions of drinking and subsequent problems deserve further exploration.
