Food-deprivation effects on punished schedule-induced drinking in rats.

Food-deprived rats (at 80% of their free-feeding weights) were exposed to a fixed-time 60-s schedule of food-pellet presentation and developed schedule-induced drinking. Lick-dependent signaled delays (10 s) to food presentation led to decreased drinking, which recovered when the signaled delays were discontinued. A major effect of this punishment contingency was to increase the proportion of interpellet intervals without any licks. The drinking of yoked control rats, which received food at the same times as those exposed to the signaled delay contingency (masters), was not consistently reduced. When food-deprivation level was changed to 90%, all master and yoked control rats showed decreases in punished or unpunished schedule-induced drinking. When the body weights were reduced to 70%, most master rats increased punished behavior to levels similar to those of unpunished drinking. This effect was not observed for yoked controls. Therefore, body-weight loss increased the resistance of schedule-induced drinking to reductions by punishment. Food-deprivation effects on punished schedule-induced drinking are similar to their effects on food-maintained lever pressing. This dependency of punishment on food-deprivation level supports the view that schedule-induced drinking can be modified by the same variables that affect operant behavior in general.

Empirically based guidelines for moderate drinking: 1-year results from three studies with problem drinkers.

OBJECTIVES: The study was conducted to refine guidelines on moderate drinking for problem drinkers, persons whose alcohol use is hazardous or harmful. Information on levels of alcohol intake unlikely to cause problems is useful for health professionals, educators, and policymakers. METHODS: Based on their reports of alcohol-related problems, participants in three studies assessing interventions to reduce heavy drinking (114 men, 91 women) were categorized as "problem-free" or "problem" drinkers at follow-up. Drinking measures were examined to identify patterns separating these outcome categories. RESULTS: Analyses using 95% confidence intervals for means on drinking measures showed that guidelines should be sex-specific. Based on analyses of positive and negative predictive value, sensitivity, and specificity, it is recommended that men consume no more than 4 standard drinks in any day and 16 drinks in any week, and that women consume no more than 3 drinks in any day and 12 drinks in any week. CONCLUSIONS: These guidelines are consistent with those from several official bodies and should be useful for advising problem drinkers when moderation is a valid treatment goal. Their applicability to the general population is unevaluated.

Drinking patterns of recent Russian immigrants and other Israelis: 1995 national survey results.

OBJECTIVES: A large group of Russian Jews has immigrated to Israel since 1989. Russia has one of the highest alcohol consumption levels in the world, while the level in Israel is among the lowest. This study was designed to provide empirical information on the drinking of these Russian immigrants compared with the drinking of other Jewish Israeli residents. METHODS: The data came from a 1995 national survey of drinking in Israel. Of 4984 Israelis, 292 were Russian immigrants who had arrived since 1989. Russians were compared with other respondents on several drinking variables. Logistic regression was the principal method of analysis, allowing the relationship to be tested with demographic and cultural variables controlled. A subsidiary analysis was conducted on data about parents' drinking from a survey of secondary school students. RESULTS: There were significant effects for Russian status for several drinking variables, with significant odds ratios ranging from 1.45 to 2.38. These results indicate that recent Russian immigrants to Israel drink more than their Israeli counterparts. CONCLUSIONS: Further investigation of the stability of these patterns may provide valuable information about cultural effects on drinking.

Coping, drinking motives, goal attainment expectancies and family models in relation to alcohol use among college students.

Associations between coping responses, drinking motivations, expectations of meeting social and academic goals, and family of origin problem drinking and measures of college students' quantity/frequency of alcohol use and social complications of alcohol use were investigated in a sample of 218 college students. Positive associations were found between "emotion-focused" forms of coping such as detachment and the criterion measures, whereas "problem-focused coping" was not significantly associated with quantity/frequency of alcohol use or drinking complications. Positive correlations were also found between drinking motives, goal attainment expectancies and family models measures and the criterion measures. Regression models constructed for alcohol quantity/frequency and drinking complications implicated the total number of drinking motives, family models of problem drinking and the coping strategy of self-blame as strongly related to criterion measures. Positive social drinking motives and coping by seeking social support were implicated as possible protective factors.

The effects of fatal vision goggles on drinking and driving intentions in college students.

The present study was designed to examine the effectiveness of Fatal Vision Goggles in reducing intentions to drink and drive. Participants performed a field sobriety task and drove in a traffic simulator while wearing the goggles. A regression analysis was performed in order to predict changes in intentions to drink and drive, using typical drinking patterns, perceived likelihood of getting into a collision when drinking and driving, self efficacy, and driving independence as predictor variables. Results showed that drinking and driving intentions were reduced following the use of Fatal Vision Goggles among those that typically drink more during outings, among those that believe the likelihood of collisions when drinking and driving are greater, and among those less likely to drive to achieve independence and autonomy. These results indicate that Fatal Vision Goggles can be an effective tool in altering drinking and driving attitudes among drivers with specific attitudinal and personal characteristics.

The provision of drinking water to veal calves for welfare purposes.

Growth performance, behavior, physiology, forestomach development, abomasal lesions, and meat quality of veal calves fed a milk-replacer diet (No Water) were compared to those obtained from calves fed the same diet and provided with increasing amounts of drinking water (Water). Two groups of 69 Polish Friesian calves, balanced according to initial BW, were assigned to two water treatments in a 3 x 2 x 2 factorial arrangement that provided solid feed in addition to the milk-replacer diet (No solid feed, 250 g x calf(-1) x d(-1) of wheat straw or the same amount of beet pulp), and the adoption of two housing systems (individual stall vs group pen). The fattening trial lasted 160 d, and calves received drinking water starting from the 2nd wk of the study. The amount of drinking water was progressively increased from 3 to 8 L x cal(-1) x d(-1). Although not dehydrated, as shown by hematocrit and Na, K, and total protein hemoconcentration, calves consumed almost all the offered amount of water throughout the fattening period. Therefore, the water provided by the milk replacer alone, which ranged between 6 to 16 L calf d(-1), was not sufficient to satisfy the need of the animal. Drinking water did not affect the calves' growth performance but it reduced nonnutritive oral behavior throughout the fattening period. Based on these results, drinking water did not cover a shortage in the calves' water requirement but it played a role in environmental enrichment. Health status was similar between treatments, although water provision reduced the episodes of feed refusal. The measurement of chronic stress by ACTH challenge showed that the administration of drinking water would be advisable when calves are fed with small amounts of solid feed for well-being. Feces consistency and animal cleanliness were not affected by drinking water. At slaughter, forestomach development was similar between treatments, and drinking water did not affect the number of calves showing rumen hair-balls and abomasal lesions. No differences in color and other meat quality traits were observed between Water and No Water calves. Despite the lack of direct effects on productive traits, when water was available, the calves drank it, and positive effects were noticed on their nonnutritive oral behaviors and chronic stress indicators.

Family experience and the motives for drinking.

Family socialization experience as reported by 128 students was posited to be related (both linearly and curvilinearly) to the seriousness of the reasons or motives for drinking. A correlational analysis, following orthogonalization of the independent variables, indicated that the frequency of intoxication by the mother was linearly and positively related to the number of reasons checked by students for drinking. Extreme closeness and extreme distance between the parents was related to drinking for personal effects (i.e., to improve self-esteem), while neutral or ambiguous attitudes toward drinking by the father were related principally to moderately serious personal and interpersonal reasons for drinking. The findings suggest that college students are at risk of becoming problem drinkers to the extent their family socialization experience included maternal deviant drinking, weak or fuzzy paternal norms about drinking, and extreme closeness or distance between parents. Family conditions that lead to poor self-esteem were seen as a necessary but not sufficient cause of problem drinking. Suggestions are made for future research and for a new, conceptually related alcoholism-prevention program.

Perceived parental/peer attitudes and alcohol-related behaviors: an analysis of the impact of the drinking age law.

This study examined the perceived change in parental and peer attitudes toward underage drinking associated with the raising of the legal drinking age and its effect on youthful alcohol use and drinking driving. The analysis was based on the New York State Youth Alcohol Survey, a series of four surveys conducted in 1982, before the enactment of the 19 drinking age law; 1983, after the enactment of the 19 drinking age law, 1985, before the 21 drinking law; and 1986, after the 21 drinking age law. Findings indicate that the effect of perceived parental attitudes is specific to underage alcohol use, but the effect of perceived peer attitudes is general to both underage and legal drinkers. Results from this study suggest that parental supervision is a key factor in enforcing the drinking age law and reducing youthful alcohol use. Parents' participation should be included in all enforcement and prevention/intervention efforts.

International study of heavy drinking: attitudes and sociodemographic factors in university students.

The authors studied the prevalence of heavy drinking among students in 21 developed and developing countries using an anonymous survey of 7,846 male and 9,892 female students aged 17 to 30 years. There were wide variations in the prevalence of drinking among countries, and the highest rates of heavy drinking (defined as 5 or more drinks for men and 4 or more drinks for women on at least 1 occasion over the past 2 weeks) were reported in Belgium, Colombia, Ireland, and Poland (men), and Ireland and England (women). Heavy drinking was associated with living away from home, having a wealthier family background, and having well-educated parents. Beliefs about the dangers to health of excessive consumption were negatively related to heavy drinking. Heavy drinking is a concern among students in several countries and is associated with greater affluence. Challenging beliefs concerning health risks is a crucial aspect of prevention in this population.

Towards a better understanding of First Nations communities and drinking and driving.

OBJECTIVES: First Nations young people are over-represented in fatal alcohol-related crashes, necessitating culturally sensitive data that sheds light on this major health issue. The objective of this study was to understand why young First Nations drivers, aged 18 to 29 years old, become involved in drinking and driving as normal behavior displayed through socio-cultural patterns. STUDY DESIGN AND METHODS: Sixty-five First Nations respondents were individually interviewed in nine Alberta locations. Semi-structured interviews, focusing on socio-cultural patterns, norms and community ethos affecting alcohol consumption, drinking and driving, and drinking and driving interventions, were used. RESULTS: Community norms play a significant role in the drinking and driving behaviors of First Nations people. First Nations communities experience reckless driving, neighbors with alcohol and drug abuse problems, violence, economic disparity, boredom and racism, all of which contribute to responses of alcohol abuse and drinking and driving. Both are considered to be normal, community-endorsed behaviors, reflecting situational needs and ready-at-hand usage. Furthermore, the grid of rural roadways is an important contributor to drinking and driving and a community sense of practical living. Also of importance was the finding that young people embraced their parents' alcohol-related problem behaviors on the basis that "what is okay for the parents is okay for me." Finally, First Nations young people believe in personally stopping a drunken person from driving, but the risk of community censure, social discomfort and risk of physical and verbal abuse mitigate against them taking action. CONCLUSIONS: Living in First Nations communities is socially complex, highly emotionally charged, and peer-pressured. Drinking and driving and alcohol abuse amongst First Nations people reflect the community social structure, daily pressures and norms of behavior. Hence, to reduce drinking and driving casualties amongst First Nations young people, intervention strategies must address systemic issues, namely local people's social realities, norms, as well as local and peer relationships.

Leech infestation and its association with water drinking habits.

OBJECTIVE: To assess the common presentations of leech infestation in leech endemic areas of Pakistan and to establish its association with unsafe water drinking habits of the individual. DESIGN: A cohort study. PLACE AND DURATION OF STUDY: CMH, Kohat, between 1st February 1997 and 30th April 2002. PATIENTS AND METHODS: Fourteen patients with leech infestation who reported to ENT department of CMH, Kohat, during the above period were selected for study. A specific comparison of their water drinking habits was made with a control group of 42 normal individuals who had come from the same leech endemic area as the first group and belonged to the same socioeconomic class. RESULTS: Twelve cases (83.4%) in the first group had unsafe water drinking habit i.e. they drank water directly from marshes without seeing its contents substituting cupped palm of hand for a drinking cup. This was in contrast to the control group where only 6 individuals (14%) gave a history of unsafe water drinking habits. Nose was the most common ENT site of leech infestation (71%) with epistaxis being the most prominent symptom. Other sites included hypopharynx (14%), nasopharynx (7 %) and oropharynx (7 %). All the 14 cases with leech infestation were males, 26.09 years being the mean age. The association between patient s unsafe water drinking habits and leech infestation in ENT region was statistically proved with odds ratio being 36. CONCLUSION: Epistaxis or any other related symptom must be taken with suspicion in leech endemic area. This condition is closely related to unsafe water drinking habits, therefore, the incidence of this infestation can be significantly reduced by educating the individuals to adopt safe water drinking habits.

Restrained drinking and cognitive control among adolescents.

The present study investigated restrained drinking and self-control in relation to alcohol consumption and problem drinking in a sample of adolescents. One hundred ninety-eight high school students (97 males and 101 females; mean age = 16.45 years) completed questionnaires that assessed levels of alcohol consumption, problem drinking, restrained drinking, and cognitive self-control. The findings were similar for males and females: higher levels of restrained drinking, as measured by cognitive emotional preoccupation (CEP), predicted higher levels of alcohol consumption and problem drinking. Moreover, it was high CEP in combination with a low score on a general measure of cognitive self-control that differentiated problem drinking from high levels of drinking. The results are consistent with previous research on young adults. The findings are discussed in relation to Baumeister and Heatherton's (1996) model of self-regulation failure.

Transitions in drinking in adolescent females: evidence from the Missouri adolescent female twin study.

BACKGROUND: Data from adult community samples indicate that alcohol dependence originates in late adolescence, thus marking that period as a fruitful one for the study of transitions in drinking. METHODS: Using retrospective data about the timing of alcohol symptom onset from 1799 female twins who participated in the Missouri Adolescent Female Twin Study (MOAFTS), we integrated person-centered (PC) and variable-centered (VC) analyses to study 1-year transitions in alcohol symptomatology. A person-year data set reflecting the onset of 15 alcohol dependence symptoms was constructed, with each year in the young woman's life from the year of her first drink to her current age counting as one observation. Latent class analysis--a PC technique--identified classes of alcohol symptomatology for each person-year, and a lag function was used to identify class membership 1 year earlier. One-year transitions in drinking--a VC analysis--were then studied. RESULTS: Smoking, marijuana use, and conduct problems were consistent promoters of transitions to more severe drinking classes, but depressed affect was not a significant predictor. Parental history of alcohol problems or excessive drinking, particularly maternal history, was a significant predictor of more serious transitions to moderate and dependent problem drinking. CONCLUSIONS: These data confirm that even over a 1-year time frame there was considerable change in drinking patterns in this adolescent sample. Smoking was as potent a risk factor as conduct problems in promoting the progression of alcohol symptomatology, and the role of familial factors was found to be influential in transitions at the more severe end of the drinking spectrum.

"Nurse, I only had a couple of beers": validity of self-reported drinking before serious vehicular injury.

BACKGROUND: Of the more than 40000 Americans killed each year in vehicular crashes, 40% are involved in alcohol-related collisions. Although self-reported alcohol use has become an anchor for alcohol intervention after traffic crashes, clinicians are often skeptical about the truthfulness of self-reporting. OBJECTIVE: To determine the validity of self-reported alcohol consumption of vehicular occupants hospitalized for a serious, alcohol-related injury. METHODS: Non-alcohol-dependent subjects 18 years and older who were injured in motor vehicle crashes were interviewed. The self-reported number of standard drinks, time that drinking commenced, sex, and weight were used to calculate estimated blood alcohol concentration. This value was compared with the blood alcohol concentration measured at admission. RESULTS: Of the 181 subjects, 60% provided sufficient data to calculate the estimated concentration. Seven men with admission concentrations of 10 mg/dL or more denied drinking. Among the 113 subjects with estimated concentrations who acknowledged drinking (excluding the 7 who denied drinking), the mean concentration at admission was 158.67 mg/dL, and mean estimated concentration was 83.81 mg/dL. According to multiple regression analyses, weight and number of drinks accounted for 3% of the variance in alcohol concentration at admission for women (R=0.174, F2,40=0.623, P=.54) and for 29% of the variance in men (R=0.543, F2,128=26.71, P< .001). CONCLUSIONS: Most persons who drink before vehicular injury acknowledge drinking. Self-reported data from men generally reflect the overall trend of alcohol consumption but with systematic underreporting. Reports from women are less predictable.

Predictors of motivation to change after medical treatment for drinking-related events in adolescents.

Characteristics associated with intention to change drinking were examined in 254 adolescents treated in an emergency department for alcohol. Younger age, living at home, lower baseline level of drinking and drinking problems, greater depression, having penalties for breaking family drinking rules, higher injury severity, being frightened, and being admitted to the hospital predicted greater intention to change drinking at the time of the event. Baseline characteristics related to being in the action stage of change 3 months later were younger age; lower drinking; having penalties for breaking family drinking rules; injury severity; and number of anticipated consequences, including being in trouble with parents. This study has implications for brief interventions that capitalize on potential teachable moments with problem-drinking adolescents.

Drinking to cope and alcohol use and abuse in unipolar depression: a 10-year model.

This study examined drinking to cope with distress and drinking behavior in a baseline sample of 412 unipolar depressed patients assessed 4 times over a 10-year period. Baseline drinking to cope operated prospectively as a risk factor for more alcohol consumption at 1-, 4-, and 10-year follow-ups and for more drinking problems at 1- and 4-year follow-ups. Findings elucidate a key mechanism in this process by showing that drinking to cope strengthened the link between depressive symptoms and drinking behavior. Individuals who had a stronger propensity to drink to cope at baseline showed a stronger connection between depressive symptoms and both alcohol consumption and drinking problems.

A randomized trial of a brief primary-care-based intervention for reducing at-risk drinking practices.

This randomized trial evaluated an intervention for reducing at-risk drinking practices in a sample of 307 patients. Eligible drinking patterns included chronic drinking (> or = 2 drinks per day in the past month), binge drinking (> or = 5 drinks per occasion at least twice in the past month), and drinking and driving (driving after > 2 drinks in the past month). Members of the intervention group received a message from their physician during their regularly scheduled visit, a self-help manual, written personalized feedback, and up to 3 telephone counseling calls. Dropout was significantly higher in the intervention than control group.

[Alcohol drinking patterns of college students].

Drinking patterns of 245 college students (88 boys and 157 girls) were surveyed by using modified questionnaire of Hirayama's 18 years ago survey and the principal results were as follows. 1. The increased tendencies of the drinking of the girl students were found here and there. 2. The principal favorite drinking places of the college students were the popular taverns (YAKITORI-YA, ODEN-YA etc.).3. The doubts or tendencies of alcohol dependence of the college students were small as the results of Hirayama's 18 years ago survey. 4. The first age of drinking tends to lower. The principal purpose of drinking of the college students was social intercourse and the motive of the drinking was principally solicitation by others and the sincere lovers of drinking were unexpectedly a few similar to Hirayama's survey. So, the counterplans to drinking habits and the alcoholism among college students should be considered from the social point of view as before.
