Lowered legal blood alcohol limits for young drivers: effects on drinking, driving, and driving-after-drinking behaviors in 30 states.

OBJECTIVES: This study evaluated the effects on drinking and driving of lowered allowable blood alcohol concentration (BAC) limits for drivers younger than 21 years in 30 US states between 1984 and 1998. METHODS: Outcome measures were based on self-reports from a cross-sectional sample of more than 5000 high school seniors in 30 states surveyed before and after BAC limits were implemented in their states. RESULTS: Frequency of driving after any drinking and driving after 5 or more drinks declined 19% and 23%, respectively. Lower BAC limits did not affect overall amount of drinking or total number of miles driven. CONCLUSIONS: Significant beneficial effects of lowered youth BAC limits have appeared despite limited publicity and enforcement of the new laws.

Drinking games and problems related to drinking among moderate and heavy drinkers.

The playing of drinking games, the quantity-frequency of alcohol consumption, and various problems related to drinking were assessed among a national sample of 3,830 alcohol consuming students from 58 American colleges and universities during the 1990-1991 academic year. Among Light-Moderate drinkers, a significantly higher proportion of students who had played a drinking game experienced 15 of 17 drinking-related problems. On the other hand, among Heavy drinkers there was little difference between game and nongame players. A higher percentage of game players had experienced five of the problems. Generally, for many problems, more than twice as many Heavy drinkers among both game and nongame players had exhibited the problem compared to more moderate drinkers. It was concluded that game playing appeared to increase problems related to alcohol primarily among more moderate drinkers whereas those who were heavy drinkers were exhibiting more problems regardless of their game-playing status. Education about the effect of game playing among students who are moderate drinkers should be addressed.

Staff drinking patterns and approach to patient drinking problems within a psychiatric hospital.

Previous studies at this VA hospital had indicated considerable evidence of "serious problem drinking" among the psychiatric patients. Mailed questionnaires to 344 treatment staff members assessed their attitudes toward and recommended approach to this problem as a function of job classification and personal drinking patterns. Results indicated that physicians, psychologists, and social workers favored a "therapeutic" approach to the problem, while nurses and nursing assistants advocated "punitive" measures. Interestingly, staff members who reported light or moderate personal drinking recommended additional therapy for these patients, while staff members who reported personal abstinence or heavy drinking generally suggested punitive actions.

The social context of drinking among high school drinking drivers.

Over 2,000 high school students were surveyed with an anonymous questionnaire to determine their frequency of drunk driving, social context of alcohol consumption, beliefs about drunk driving, and quantity and frequency of alcohol consumed. About 10% of the sample was identified as drunk drivers and they were compared with non-drunk driving drinkers according to a number of measures of where and why they drank. The results revealed highly significant differences in the social context of alcohol consumption for beer, wine, and liquor consumption. Across all three beverage categories, the most important discriminating social context factors were drinking at a dormitory and drinking to get along better on dates. Beer and liquor consumption were more important than wine consumption for discriminating drunk drivers from the non-problem drinking high school population. Quantity and frequency measures of alcohol consumption along with belief measures about drinking and driving did not substantially increase the discrimination between the two groups, but significantly increased the predictive power in a multiple regression analysis including the social context of alcohol consumption items.

Drinking in bars: an observational study of companion status and drinking behavior.

The drinking behavior of 329 patrons was observed in three public drinking settings in Boston. Variations in drinking behavior and patron characteristics at each site were noted. Group setting was significantly related to duration of stay among males in two sites. Duration of stay was related to level of consumption in all sites for men and women. The relationship between companion status and drinking behavior varied by site and sex of patron.

Drinking reasons, alcohol consumption levels, and drinking locations among drunken drivers.

In a DUI offender sample, four drinking reason factors are regressed on alcohol consumption variables and frequency of drinking in seven types of locations. Drinking for "pleasure" and "opposite sex/drunkenness" reasons are associated with both quantity consumed per occasion and away-from-home locations such as automobiles, bars, and parties, suggesting high traffic accident risk. "Escapism" reasons are related to quantity consumed per occasion, but are only weakly associated with specific locations; and "sociability" reasons are associated with drinking in friends' homes, but are not related to high consumption levels. Implications for DUI countermeasures are discussed.

Relationships among alcohol availability, drinking location, alcohol consumption, and drinking problems in adolescents.

We examined relationships among perceived alcohol availability, drinking location, alcohol consumption, and drinking problems. Subjects were 3,372 adolescent drinkers, ages 16-18, who participated in the Communities Mobilizing for Change on Alcohol Project baseline survey. Mixed-model regression was employed to identify predictors of alcohol consumption and drinking consequences. Perceived alcohol availability was significantly associated with higher levels of alcohol consumption for males. Drinking in a public location with higher levels of alcohol consumption for females. Results underscore the importance of youth alcohol assessibility.

Local cerebral glucose utilization rates in alcohol-naïve high-alcohol-drinking (HAD) and low-alcohol-drinking (LAD) rats.

BACKGROUND: The present study compared baseline local cerebral glucose utilization (LCGU) values within reward-relevant brain regions in alcohol-naïve, adult male high-alcohol-drinking (HAD) and low-alcohol-drinking (LAD) rats from replicate lines 1 and 2. METHODS: 2-[14C]Deoxyglucose ([14C]2-DG) was injected (125 microCi/kg) intravenously during the rats' dark cycle. Timed arterial blood samples were collected over 45 min and assayed for glucose as well as [14C]2-DG content. Rats were then decapitated; their brains quickly removed and frozen in isopentane at -50 degrees C. Coronal sections from each brain were apposed to film and exposed for 2 days. Image densities were analyzed using quantitative autoradiography. RESULTS: Data were collected from several key limbic (nucleus accumbens, ventral tegmental area, olfactory tubercle, amygdala, hippocampus, ventral pallidum, and septum), basal ganglia, cortical (medial prefrontal, frontal, parietal, temporal, occipital, entorhinal, pyriform, and cingulate), and subcortical (thalamus, habenula, and superior colliculus) structures. Because there were no significant differences between the replicates within each drinking line, data from the two replicates were combined to determine drinking line differences. When both replicate lines were combined, there were trends toward higher (approximately 15%) LCGU rates in HAD (n = 15) versus LAD (n = 16) rats within the parietal and occipital cortices, but neither of these line differences reached statistical significance (p < 0.01). CONCLUSIONS: The findings suggested that, within the HAD and LAD replicate rat lines, the selection for alcohol preference did not lead to differences in functional brain activity, as measured with the 2-DG method.

Binge drinking, sensible drinking, and abstinence after alcohol-related vehicular crashes: the role of intervention versus screening.

Brief interventions have been shown to reduce problem drinking in a variety of populations and settings. The hypothesis for our randomized trial was that individuals injured in alcohol-related crashes who received a more intensive intervention (brief counseling) would have reduced binge drinking as compared to those with a less intensive intervention (simple advice) and controls. Non-alcohol dependent, seriously injured individuals (N = 186) were enrolled in the protocol. At baseline, mean binges/month (b/m) were 5.88 and at 12 months were 2.02 b/m. Although there was no significant difference by condition, at 12 months the brief counseling group had the lowest rate of binge drinking (1.97 b/m). Whether these drinking patterns were a result of the crash, injury, screening for alcohol use, or combination of these factors is difficult to determine.

Familial alcoholism and problem drinking in a national drinking practices survey.

This study examined the prevalence of alcoholism and problem drinking among the first degree relatives of respondents in a national survey. A stratified area-probability sample of adults 18 years of age or older living in households in the U.S. was used for this analysis. Data were collected on familial alcoholism/problem drinking as well as the prevalence of alcohol problems and depressive symptoms of the respondents themselves. Overall, women reported more alcoholic/problem drinking first degree relatives than men. This relationship was enhanced for women with alcohol problems alone or in conjunction with depressive symptoms. However, rates of reported familial alcoholism/problem drinking among men and women who had depressive symptoms only were quite similar. The implications of these findings are discussed.

Removal of saxitoxins from drinking water by granular activated carbon, ozone and hydrogen peroxide--implications for compliance with the Australian drinking water guidelines.

In a laboratory-scale trial, we studied the removal of saxitoxins from water by ozone, granular activated carbon (GAC) and H(2)O(2), and considered the implications of residual toxicity for compliance with the Australian drinking water standards. Cell-free extracts of Anabaena circinalis were added to raw, untreated drinking water obtained from a water supply reservoir to provide a toxicity of 30 microg (STX equivalents)l(-1). Ozone alone, or in combination with H(2)O(2), failed to destroy the highly toxic STX and GTX-2/3, and only partially destroyed dc-STX, and the low-toxicity C-toxins and GTX-5. In all cases, the toxicity of the water was reduced by less than 10%. GAC removed all of the STX, dc-STX and GTXs, but only partially removed the C-toxins. However, the residual toxicity was reduced to the suggested Australian drinking water guideline concentration of 3 microg (STX equivalents)l(-1) without O(3) pre-treatment. Modelling the spontaneous chemical degradation of residual C-toxins following treatment shows that residual toxicity could increase to 10 microgl(-1) after 11 d due to formation of dc-GTXs and would then gradually decay. In all, residual toxicity would exceed the Australian drinking water guideline concentration for a total of 50 d.

Aluminium content of drinking waters, fruit juices and soft drinks: contribution to dietary intake.

Concentrations of aluminium in drinking waters (tap water, still mineral water and sparkling mineral water), fruit juices and soft drinks were determined using graphite furnace atomic absorption spectrometry (GFAAS) of samples processed with a HNO3-V205 acid digestion pre-treatment. In water samples, aluminium was determined directly. We verified the sensitivity, accuracy and precision of the method and ruled out matrix interferences. In analysed samples, aluminium values ranged from 4.2 to 165.3 microg/l in drinking water (n=41), from 49.3 to 1,144.6 microg/l in fruit juices (n=47), and from 44.6 to 1053.3 microg/l in soft drinks (n=88). According to the type of container (glass or can) statistically significant differences (P<0.01) have been demonstrated. Considering the mean daily individual consumption of these beverages in Spain, the daily dietary intake of Al supplied by this source is estimated as 156 microg/person/day. This study contributes new data on the Al content of a variety of foods and beverages in Spain and to estimate reliably the total dietary intake of aluminium.

"Through a drinking glass and what was found there": pseudocontamination of a hospital's drinking water.

OBJECTIVE: Examination of suspended macroscopic debris that was noted in hospital cafeteria drinking water over a prolonged period of time. SETTING: A tertiary care hospital. DESIGN: A retrospective description of events. METHODS: Conventional medical microbiology techniques were employed to determine if contamination of drinking water had occurred. RESULTS: Microscopic examinations of the debris showed live nematodes similar to Strongyloides stercoralis rhabditiform larvae and amoebic trophozoites. A culture of an ice container in the cafeteria yielded coliform bacteria. Hospital employees lost work because of a diarrheal illness thought to be contracted from drinking cafeteria water. Further investigation revealed that the debris contained numerous ciliated organisms, nematodes, fresh water amoebae, bacterial mats, flagellated fungi, and unidentified cysts suggesting that the debris was of a freshwater origin rather than fecal contamination. Another hospital served by a collateral city water line experienced a similar problem. The debris was observed in November when lake water in the reservoir undergoes inversion. CONCLUSIONS: Nonpathogenic freshwater microbiota probably originating from the city reservoir were the cause of pseudocontamination of hospital drinking water.

Alcohol availability, drinking contexts and drinking problems: the Iowa experience.

Before/after survey data were used to investigate the effects that a wine and spirits privatization-induced increase in alcohol availability might have had on drinking contexts and, in turn, what effect any context changes might have had on specific drinking-related troubles. State surveys representing the aged 18+ noninstitutionalized population of Iowa were conducted in 1985, prior to the wine privatization; in 1986, after the wine privatization but before the spirits privatization; and in 1989, after both wine and spirits sales had been privatized. Despite substantial increases in the number of off-premise outlets for bottled wine and spirits following their privatizations, there was little or no change in the frequency of drinking in several different contexts or in the specific kinds of drinking-related problems studied.

Chronic drinking, binge drinking and drunk driving.

Data from the Brief Risk Factor Surveillance System on 47 states were examined in an ecological analysis of the relationship between rates of binge drinking, chronic drinking, and driving while intoxicated (DWI). DWI rates were significantly associated with rates of binge drinking but not with chronic heavy drinking. This finding has implications for the nature and targets of efforts toward prevention.

Young women and alcohol: psychosocial factors associated with their own drinking, their fathers' drinking, and both.

Psychosocial factors associated with young women's own alcohol consumption, and that of their fathers, were assessed in a sample of 231 females (mean age: 18.0 years) from the Hunter Region, NSW, Australia. Consistent with prior research, we found some evidence of poorer adjustment in girls who drank heavily and among daughters of high drinkers. In addition, we found that the "psychosocial profiles" associated with girls' and fathers' drinking were quite different, which argues against a simple additive model which might predict poorer adjustment in high drinking daughters of high drinking men. One interesting finding was that discordance between girls' and fathers' drinking patterns was independently related to some psychosocial problems.

A characterization of approach and avoidance learning in high-alcohol-drinking (HAD) and low-alcohol-drinking (LAD) rats.

BACKGROUND: This study was undertaken as one of a series of experiments designed to examine basic behavioral characteristics present in rats bred specifically for alcohol preference. The basic premise for these experiments has been the idea that alcohol-preferring and -nonpreferring rats may differ in basic activation and inhibition control mechanisms that govern behavior and that different lines of alcohol-preferring rats may demonstrate differential deficits in behavioral activation and behavioral inhibition tendencies. In the present experiment, conditioned approach and avoidance behaviors were studied in alcohol-naïve high-alcohol-drinking (HAD), low-alcohol-drinking (LAD), and N/NIH rats to evaluate behavioral activation in this line of rats. METHODS: High alcohol drinking (HAD1), low alcohol drinking (LAD1), and N/Nih stock rats were trained to press a response bar during a tone signal to avoid a mild foot shock or receive a food reward. In addition, HAD2 and LAD2 rats, independently-bred replicate lines of the HAD1/LAD1 rats, were trained on the avoidance task. RESULTS: Although the HAD1 rats easily learned the appetitive version of the bar-pressing task, they did not learn the avoidance response. The LAD1 and N/Nih rats learned both the approach and the avoidance tasks normally. Similar to HAD1 rats, the HAD2 rats did not learn the avoidance response whereas LAD2 rats showed significant avoidance performance levels. CONCLUSIONS: The present data demonstrated that both HAD1 and HAD2 rats had a rather specific behavioral activation deficit: although they easily learned to press a bar to receive food reinforcement, they did not learn to press the bar to avoid a foot shock. We speculate that this failure to learn the avoidance response may be related to heightened anxiety in the HAD rats and that this excessive anxiety may lead to the development of high levels of alcohol consumption in these selectively bred rats.

Genetics of alcoholism: simultaneous presentation of a chocolate drink diminishes alcohol preference in high drinking HAD rats.

Through selective crossbreeding of the N/Nih heterogeneous stock of rats, two genetic lines of rats have been developed that are categorized by their preference for ethyl alcohol as high alcohol drinking (HAD) and low alcohol drinking (LAD) animals. Corresponding to other strains of rat bred for alcohol selection or rejection, they were subdivided on the basis of their intake of a solution of 10% alcohol vs. water. The present experiments were designed to determine whether the HAD-1 and LAD-1 lines are similar to the P and NP rats in their profile of alcohol consumption. Five successive three-bottle preference tests for alcohol drinking in the presence of water were undertaken in both HAD (n = 9) and LAD (n = 10) rats as follows: 10% alcohol for 5 days; 3-30% concentrations of alcohol increased over 11 days; the maximally preferred concentration of alcohol for 5 days; this maximally preferred concentration of alcohol plus either chocolate Slender for 5 days, or an aspartame solution for 5 days. The intake of alcohol of the LAD rats during the 10% test was 0.4 g/kg/day, whereas during the 3-30% test, the maximum intake was 1.7 g/kg/day; their maximally preferred concentrations ranged between 7% and 9% alcohol. In contrast, the intake of 10% alcohol of the HAD rats was 6.5 g/kg/day, whereas during the 3-30% test the mean daily intake was 6.6 g/kg/day; the maximally preferred solutions of the HAD rats ranged between 13 to 20%, with the mean maximum intake of 10.57 g/kg/day reached at the 20% concentration.(ABSTRACT TRUNCATED AT 250 WORDS)
