Fluoride is unable to reduce dental erosion from soft drinks.

The main aim of the present study was to compare the erosive capabilities of some fruit-flavoured drinks, fresh or saturated with CaF2, with their content of acids and with previous results from some carbonated soft drinks. The other aim was to measure and compare the rates of dissolution of CaF2 in some carbonated and non-carbonated drinks and water. Seven commercially available fruit-flavoured drinks were diluted for drinking. Two human molars, each with two approximately 4 x 4 mm windows, were exposed continuously to 500 ml of each drink with or without prior equilibration with CaF2 under gentle agitation for 48 h. The depths of the erosions were then measured on microradiographs made from sections. Dissolution rate of CaF2 was measured by suspending 0.5 g of the salt in 0.5 litre of the drinks for 2, 10 and 60 min followed by solution analysis. The pH of the drinks was 2.83-3.51. The amount of NaOH required to bring pH to 5.5 ranged from 12-42 mmol/l, which is more than the amount necessary for most carbonated soft drinks. Equilibration with CaF2 gave total fluoride concentrations of 3-8 ppm. The depths of the lesions induced by the drinks without added fluoride were 450-625 microm whilst those developed by the drinks equilibrated with CaF2 were 350-625 microm. The dissolution of CaF2 was faster in the carbonated drinks and in distilled water than in the non-carbonated drinks. In conclusion, non-carbonated fruit-flavoured drinks contain considerable amounts of acids which, in vitro, induce erosions in teeth similar to those induced by carbonated soft drinks. Saturation with CaF2 reduced the in vitro development of erosions by 28% induced by drinks with pH above 3; in drinks with pH below 3, erosions were not affected by pH, despite total fluoride concentrations of up to 20 ppm.

Problem drinking and intimate partner violence.

OBJECTIVE: This study examined the role of problem drinking in intimate partner violence (IPV) perpetration and victimization for men and women. We assessed (1) whether the relationship between problem drinking and IPV was spurious and (2) if relationship dissatisfaction and partner drinking mediated the effects of problem drinking on IPV. METHOD: Five waves of longitudinal data from a nonclinical sample (N = 725; 400 women), aged 12 through 31 years, were analyzed to determine the effects of problem drinking on IPV after controlling for eight common risk factors. Regression analyses were conducted to determine whether relationship dissatisfaction and partner drinking patterns mediated the effects of problem drinking on IPV after controlling for these same risk factors. RESULTS: With controls, problem drinking significantly predicted perpetration and victimization for men and women. Partner drinking was not related to perpetration or victimization for men. For women, partner drinking was strongly related to perpetration and victimization. It fully mediated the effects of problem drinking on perpetration, but did not mediate these effects on victimization. Relationship dissatisfaction fully mediated the effects of problem drinking on male and female perpetration and partially mediated the effects on male victimization. Relationship dissatisfaction did not mediate the effects of problem drinking on female victimization. CONCLUSIONS: The relationship between problem drinking and IPV was not spurious for men or women. Heavier drinking by partners put women at greater risk for perpetration and victimization and mediated the effects of their own problem drinking on perpetration. Programs that prevent and treat problem drinking among young men should have a beneficial impact on reducing IPV.

Young drivers' health attitudes and intentions to drink and drive.

PURPOSE: To evaluate young drivers' intentions to drink and drive in the context of a health attitude model, the Protection Motivation Theory (PMT). METHODS: Licensed drivers attending college and ranging from 17 to 20 years of age (n = 304) completed questionnaires assessing PMT variables in the context of drinking and driving. More than half the sample consisted of females (62%) and most were white (89%). The drivers rated the extent to which they found drinking and driving to be personally rewarding, their perceived vulnerability to the risks of drinking and driving, the severity of the risks, the response efficacy of alternative adaptive responses to drinking and driving, their self-efficacy for implementing alternative responses, and the response costs associated with the responses. The relationship between PMT variables and drivers' intention to drink and drive was tested using hierarchical multiple regression analyses with attitudes concerning drinking and driving (rewards, vulnerability, and severity) entered in the regression equation first, followed by attitudes concerning alternative adaptive responses (response efficacy, self-efficacy, and response costs). RESULTS: The PMT model was found to predict intentions to drink and drive. Young drivers who perceived rewards for drinking and driving and who felt vulnerable to the risks of drinking and driving were significantly more likely to report intentions to drink and drive. Attitudes about alternative adaptive responses to drinking and driving, including perceiving low self-efficacy for implementing alternative responses and perceiving personal costs for engaging in alternative options, also contributed to drivers' intentions to drink and drive. CONCLUSIONS: Although teenaged drivers are well informed of the dangers of drinking and driving, they still put themselves and others at risk by driving after consuming alcohol. Health professionals promoting safer alternatives might consider how young drivers' attitudes about both drinking and driving and alternative adaptive responses contribute to their intentions to drink and drive.

Is there a relationship between excessive drinking and functional impairment in older persons?

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

Effects of using recommended coping strategies on drinking outcome following a brief intervention.

AIMS: To explore the unique contribution to outcome drinking of clients' use of six strategies for moderating drinking, after statistically accounting for variance explained by some client and intervention variables. DESIGN: An exploratory hierarchical regression analysis assessed the contributions to variance in drinking outcome of pre-intervention (client characteristics, baseline drinking), assignment (level of assessment, therapist experience) and early follow-up variables. Data came from an experimental trial which evaluated the effect of adding assessment to provision of a self-help book to heavy drinkers. SETTING: Diverse Ontario communities. PARTICIPANTS: Heavy drinkers (99 males, 56 females) were selected from 185 media-recruited applicants who were screened by telephone to exclude cases with severe alcohol-related problems. Their mean (+/- SD) pre-admission weekly quantity of alcohol consumed was 22 +/- 15 drinks. Follow-up rates at 3 and 12 months were 92% and 88%. MEASUREMENTS: Regressed onto weekly quantity at follow-up were: client characteristics, previous measures of weekly quantity, experimental condition and use of the menu of strategies (setting goals for drinking, keeping track of drinking, pacing drinking, planning ahead to avoid heavy drinking, developing free-time activities and coping with problems without drinking). FINDINGS: At 3 months the variables predicting lower weekly quantity were: pre-intervention weekly quantity, developing free-time activities, setting goals for drinking and condition. Lower weekly quantity at 12 months was predicted by lower 3-month and pre-intervention weekly quantity, and regular use of: coping with problems without drinking, setting goals for drinking and keeping track of drinking. CONCLUSIONS: This descriptive study revealed a positive association between level of use of recommended coping strategies at follow-up and drinking outcome. Controlled studies of the effects of strategy use on drinking outcome are therefore warranted.

Public opinion on the health benefits of moderate drinking: results from a Canadian National Population Health Survey.

AIMS: To explore beliefs about the health benefits of drinking alcohol in the Canadian population. DESIGN: Secondary analysis of data from a national population health survey. PARTICIPANTS: Canadians age 12 or older (weighted n = 72375) in all provinces but Alberta excluding those living in remote regions, native reserves and armed forces bases. MEASURES: Responses to questions concerning the definition of moderate drinking and the belief that moderate drinking can be good for health. Self-reports of age, gender, province of residence, quantity and frequency of drinking, health problems and indicators of alcohol dependence. FINDINGS: Fifty-seven per cent of respondents believed that moderate drinking has health benefits. Forty-seven per cent defined moderate drinking as drinking less than one drink a day and believed this to be good for health. Twelve per cent defined moderate drinking as one or more drinks a day and believed this is good for health. Belief in the health benefits of moderate drinking was more common among men, those age 45 or older, residents of Ontario and Quebec, more frequent drinkers and those with ischaemic heart disease. Those who believed in the health benefits of at least one drink a day were more often males, older persons and frequent, heavy drinkers. CONCLUSIONS: Belief in the health benefits of moderate drinking is generally associated with a conservative definition of moderate drinking. However, some drinkers at risk for alcohol problems may be influenced to drink by the belief that this can have health benefits or use this belief as an excuse for drinking.

Underage drinking: frequency, consequences, and interventions.

OBJECTIVES: To examine the frequency of underage drinking, driving after drinking and alcohol-related crashes, trends in these behaviors, and promising interventions. METHODS: We examined drinking and drinking- and-driving behaviors reported in the United States in the 2001 U.S. National Household Survey of Drug Abuse, the Centers for Disease Control and Prevention 2001 Youth Risk Behavior Survey, the 1992 National Longitudinal Alcohol Epidemiologic Study, and the 1999 National Survey of Drinking and Driving conducted for the National Highway Traffic Administration. We also examined the 1999 European School Survey Project on Alcohol and Other Drugs. Alcohol-related fatal crashes were examined from the U.S. Fatality Analysis Reporting System. Evaluation of interventions to reduce teenage drinking and driving after drinking were reviewed. RESULTS: In the United States, 19% of youth ages 12-20 consumed five or more drinks on an occasion in the past 30 days. Although European nations have lower legal drinking ages (16-18) than in the United States (21), similar proportions engage in underage drinking. In two-thirds of European countries, a greater percentage of 15-16 year-olds drank five or more drinks on an occasion in the past month than in the United States. In both the United States and Europe, the earlier people begin to drink, the greater the likelihood of developing alcohol dependence and other alcohol-related problems, including alcohol-related crash involvement, during adolescence and adult years. During the past 20 years alcohol-related traffic deaths among people younger than 21 have been cut in half in the United States, but progress has halted since 1995 and the problem is still large. Interventions shown by research to reduce alcohol-related crashes among youth include raising the legal drinking age to 21, zero tolerance laws, and some interventions that are family, school, or community based. CONCLUSIONS: Despite research showing that a variety of interventions can reduce underage drinking and alcohol-related crash fatalities, the frequency of these behaviors remains high and the average age of drinking initiation is declining in the United States. Efforts are needed to enhance publicized enforcement of underage drinking laws. Comprehensive community interventions that include enforcement of these laws also are needed.

Pattern of drinking and fatal injury: a population-based follow-up study of Finnish men.

AIM: To find out how the frequency of drinking one to two drinks, three to four drinks and five or more drinks of alcohol per drinking occasion predicts injury mortality in 16 years of follow-up among the Finnish 15-69-year-old male population. DESIGN: Three alcohol surveys conducted in 1969, 1976 and 1984 were pooled and linked with mortality information from the national cause of death register. METHOD: Cox proportional hazard models were used for analysing the survival time data. FINDINGS: Drinking at the level of one to two drinks, regardless of frequency, did not elevate the risk of fatal injury, nor did drinking at the level of three to four drinks. Drinking five or more drinks at a time significantly increased the risk of fatal injury in graded relation, compared with those who never drank at that level. The risk was highest for those who drank five or more drinks at a time at least weekly (RR = 5.78, 95% CI = 2.80-11.94), when adjusted for possible confounders. CONCLUSIONS: We found that besides the total volume of consumption, a drinking pattern that involves drinking occasions when consumption exceeds four drinks of alcohol at a time leads to a significant increase in the risk of fatal injury among Finnish men. The risk is highest among those who have the highest annual number of heavy drinking occasions. The finding does not support the hypothesis that alcohol tolerance would lower the risk of fatal injuries among frequent heavy drinkers.

Many college freshmen drink at levels far beyond the binge threshold.

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

Young people, alcohol, and designer drinks: quantitative and qualitative study.

OBJECTIVE: To examine the appeal of "designer drinks" to young people. DESIGN: Qualitative and quantitative research comprising group discussions and questionnaire led interviews with young people accompanied by a self completion questionnaire. SETTINGS: Argyll and Clyde Health Board area, west Scotland. SUBJECTS: Eight groups aged 12-17 years; 824 aged 12-17 recruited by multistage cluster probability sample from the community health index. RESULTS: Young people were familiar with designer drinks, especially MD 20/20 and leading brands of strong white cider. Attitudes towards these drinks varied quite distinctly with age, clearly reflecting their attitudes towards and motivations for drinking in general. The brand imagery of designer drinks-in contrast with that of more mainstream drinks-matched many 14 and 15 year olds' perceptions and expectations of drinking. Popularity of designer drinks peaked between the ages of 13 and 16 while more conventional drinks showed a consistent increase in popularity with age. Consumption of designer drinks tended to be in less controlled circumstances and was associated with heavier alcohol intake and greater drunkenness. CONCLUSIONS: Designer drinks are a cause for concern. They appeal to young people, often more so than conventional drinks, and are particularly attractive to 14-16 year olds. Consumption of designer drinks is also associated with drinking in less controlled environments, heavier drinking, and greater drunkenness. There is a need for policy debate to assess the desirability of these drinks and the extent to which further controls on their marketing are required.

Contribution of drinking patterns to differences in rates of alcohol related problems between three urban populations.

OBJECTIVES: To examine, on empirical data, whether drinking patterns, in addition to overall alcohol consumption, contribute to differences in rates of alcohol related problems between populations. DESIGN: Cross sectional survey. SETTINGS: One Russian, one Polish, and one Czech city. PARTICIPANTS: 1118 men and 1125 women randomly selected from population registers. MAIN OUTCOME MEASURES: Problem drinking; negative social consequences of drinking; alcohol consumption and drinking pattern. RESULTS: Rates of problem drinking and of negative consequences of drinking were much higher in Russian men (35% and 18%, respectively) than in Czechs (19% and 10%) or Poles (14% and 8%). This contrasts with substantially lower mean annual intake of alcohol reported by Russian men (4.6 litres) than by Czech men (8.5 litres), and with low mean drinking frequency in Russia (67 drinking sessions per year, compared with 179 sessions among Czech men). However, Russians consumed the highest dose of alcohol per drinking session (means 71 g in Russians, 46 g in Czechs, and 45 g in Poles), and had the highest prevalence of binge drinking. In women, the levels of alcohol related problems and of drinking were low in all countries. In ecological and individual level analyses, indicators of binge drinking explained a substantial part of differences in rates of problem drinking and negative consequences of drinking between the three countries. CONCLUSIONS: These empirical data confirm high levels of alcohol related problems in Russia despite low volume of drinking. The binge drinking pattern partly explains this paradoxical finding. Overall alcohol consumption does not suffice as an estimate of alcohol related problems at the population level.

Drinking and driving: explaining beverage-specific risks.

OBJECTIVE: This study tested whether the association of beer drinking with drinking and driving is due to cultural norms or is an artifact arising from the demographic profile of beer drinkers (young and male), the drinking patterns of this subpopulation (frequent and heavy), and the venues in which they prefer to drink (bars and restaurants). METHOD: Telephone survey data from six U.S. communities were used to establish the demographic characteristics of drinkers, their consumption patterns, beverage preferences, preferred drinking venues and self-reported drinking and driving rates. The survey completion rate was 64.6%. A total sample of 5,231 drinkers was divided into test and validity samples. After deletion of cases with missing data, the test sample included 2,275 drinkers, of whom 985 had driven after drinking. RESULTS: Controlling for a broad set of covariates, the analyses showed that frequent consumers were more likely to drink outside the home, preferred beer and spirits to wine, and were more likely than others to drink and drive. Beverage preferences were not directly associated with drinking and driving. Beer drinkers, however, were from the subpopulation most likely to drink and drive: heavier drinking younger men, who prefer to drink at bars and restaurants. CONCLUSIONS: These results suggest that the association of beer consumption with drinking-driving arises from the circumstances in which the subpopulation of beer drinkers more commonly find themselves (as a result of their efforts to maximize, within economic constraints, the social and amenity value of drinking), as opposed to any culturally induced disposition beer drinkers may have to drink and drive.

Associations between adolescent drinking and driving involvement and self-reported risk and protective factors in students in public schools in Washington State.

OBJECTIVE: This study examines associations between self-reported drinking and driving or being a passenger of a drinking driver and risk and protective factors in a general population of adolescents. METHOD: We used a two-staged sampling procedure to survey 2,955 students in Washington State public schools in Grades 9-12. Students were asked if they were a passenger of, or had been, a drinking driver in the previous month. They were also asked about individual, parent, school and community risk and protective factors. Comparisons were made using hierarchical polychotomous logistic regression, entering age and gender and parent, school and community protective factors at the first step and individual risk factors at the second step. RESULTS: Driving after drinking in the previous month was reported by 12.1% of respondents and riding with a drinking driver was reported by an additional 17.6% of respondents. At the first step, driving after drinking was more likely and riding with a drinking driver was less likely among youth who were age 16 or older, and male students were more likely than female students to report driving after drinking. Parent, school and community support were each significantly associated with less driving after drinking, and school support was significantly associated with less riding with drinking drivers. At the second step, higher quantity and frequency of drinking, more smoking cigarettes and drug use and less seat belt use were each associated with both drinking and driving and riding with drinking drivers. Gun carrying was also associated with driving after drinking. CONCLUSIONS: Drinking and driving behaviors were associated with risk and protective factors in the community, school, family and individual. Pilot prevention programs should test the effectiveness of reducing drinking and driving involvement by addressing such factors.

Alcohol use in the year before marriage: alcohol expectancies and peer drinking as proximal influences on husband and wife alcohol involvement.

BACKGROUND: Models of adolescent alcohol involvement that include individual difference, family, and peer risk factors indicate a significant association between the drinking of adolescents and that of their peers. Peer drinking influences, however, have not been investigated extensively in integrative models of adult drinking. The purpose of this study was to test a model of adult drinking that incorporated the potentially important risk factor of partner drinking and in which proximal risk factors (peer drinking, alcohol expectancies) were hypothesized to be strongly associated with adult alcohol use and to mediate relationships between more distal risk factors and drinking. METHODS: Couples (n = 389) were assessed at the time of their first marriage. Separate, self-administered questionnaires were completed at home by both husbands and wives. Distal risk factors included family history of alcoholism, antisocial behavior, and depressive symptomatology. Substantive relationships were tested in a model that included spousal associations with respect to distal risk factors, proximal risk factors, and drinking. RESULTS: Findings demonstrate the unique association of alcohol expectancies and peer drinking with adult alcohol use. Of particular relevance is the significance of the social network as a correlate of adult drinking. A peer network characterized by a higher level of alcohol involvement was strongly associated with heavier drinking among both men and women. This relationship was independent of sociodemographic and individual difference factors, alcohol expectancies, and partner's drinking. Results also demonstrate the similarity between husband and wife drinking, an association that cannot be attributed to assorting with respect to the other risk factors. CONCLUSIONS: The social network continues to significantly impact drinking behavior in adulthood. The relevancy of peer and partner drinking influences to adult alcohol involvement suggests that the immediate social environment may have a prominent role in the continuity/discontinuity of heavy or problem drinking during the transition to marriage.

Experimental sports drinks with minimal dental erosion effect.

The effects of new experimental sports drinks on dental enamel were studied in vitro using bovine tooth specimens. Profilometric analysis was used to measure the loss of tooth material after immersion of the specimens in the drinks. Thereafter the specimens' surface hardness was measured and scanning electron microphotographs were taken. In addition, 13 commercial sports drinks and experimental drinks containing either citric acid or malic acid were tested for their capacity to dissolve hydroxyapatite in vitro. The erosive effect increased markedly with decreasing pH. The citric acid containing drinks were more erosive than malic acid containing drinks. No erosion was observed with the malic acid containing drink (pH 5.90) but the drink of similar composition containing citric acid caused an erosion 1.3 +/- 1.1 microns deep and a commercial citric acid containing drink caused a lesion 12.3 +/- 4.5 microns deep after 120 min immersion. Softening of enamel was greater in specimens immersed in citric acid than in those immersed in malic acid containing drink. The in vitro hydroxyapatite dissolving effect of the commercial sports drink samples studied (all having a pH under 4.22) was markedly greater (0.48-4.38 mmol/l) than that of the malic acid containing experimental drink (pH 5.50, Ca++ concentration in the supernatant 0.19 mmol/l) and of the similar citric acid containing drink (0.35 mmol/l). The hydroxyapatite dissolving effect of both drinks started to be marked at a pH level of about 5.0 but increased thereafter exponentially with decreasing pH. At pH levels above 4.0 the hydroxyapatite dissolving effect of citric acid containing drinks was greater than that of malic acid containing drinks.

At-risk drinking among patients making routine primary care visits.

BACKGROUND: Addressing non-alcoholic, at-risk patterns of alcohol consumption that are associated with increased morbidity and mortality is an important health care priority. OBJECTIVE: The objective was to describe the prevalence and characteristics of at-risk drinkers in a population-based sample of adults with routine primary care visits. METHODS: Three thousand four hundred thirty-nine patients with advance appointments in 23 primary care practices completed a health survey prior to their visit. At-risk drinking was defined as consuming an average of two or more drinks per day (chronic drinking), or two or more occasions of consuming five or more drinks in the past month (binge drinking), or, in the past month, one or more occasion of driving after consuming three or more drinks (drinking and driving). RESULTS: Prevalence was: 11% at-risk drinking; 63% light to moderate drinking; 26% abstinence. Abstainers differed from alcohol users on demographics (older, fewer Caucasian, lower income, more unemployed), other health behaviors (less exercise, lower rates of smoking, and marijuana and cocaine use), and family history of alcohol problems (lower). Abstainers also reported poorer physical and psychological health. Compared to light to moderate drinkers, at-risk drinkers were more likely to be male, unmarried, and to use other substances (tobacco, marijuana, and cocaine). Among at-risk drinkers, those with two or more risk factors were more likely male, consumed more alcohol per week, had higher AUDIT scores and were more motivated to change their drinking. Among those with only one risk factor, binge drinkers reported high rates of tobacco and marijuana use, relatively poor perceived health, and the highest proportion of negative consequences from drinking. CONCLUSIONS: At least 1 in 10 patients making routine primary care visits have drinking practices that place them at risk for negative consequences from drinking. Three drinking patterns that can be used to define at-risk drinking are relatively distinct.

Histamine H3 receptors contribute to drinking elicited by eating in rats.

A role for endogenous histamine and its H3 receptor subtype for mediating drinking elicited by eating was examined in adult male Sprague-Dawley rats. The i.p. injection of the H3 agonist R-alpha-methylhistamine (Ramh, 2.5 mg/kg) shortened the latency to initiate drinking and increased 1-h water intake in nondeprived rats freely eating pellets and drinking water. The ICV injection (through a surgically implanted chronic cannula) of 10 micrograms Ramh increased water intake; this Ramh-induced drinking was abolished by previous ICV injection of the H3 antagonist thioperamide (Th, 60 micrograms). For rats drinking and eating after 24-h food deprivation, s.c. Th inhibited drinking behavior: for example, 10 mg/kg Th s.c. delayed the latency to initiate drinking and inhibited 1-h water intake without inhibition of food intake. In contrast, 60 micrograms Th ICV failed to inhibit food-related drinking in rats eating after food deprivation. For nondeprived rats eating a small cracker, 10 mg/kg Th s.c. delayed the latency to initiate drinking and abolished water intake without effect of eating, and 60 micrograms Th ICV had similar effects upon drinking elicited by ingestion of cracker. The IG infusion (through a surgically implanted gastric catheter) of 2 ml 600 or 900 mOsm/kg NaCl, a treatment that is subthreshold for increase in systemic plasma osmolality at the initiation of drinking, elicited drinking that was abolished by 10 mg/kg Th s.c. and attenuated by 60 micrograms Th ICV. The IG infusion of 2 ml 1800 mOsm/kg NaCl, a treatment that is above threshold for increase in systemic plasma osmolality, elicited drinking that was attenuated by 10 mg/kg s.c. or 60 micrograms Th ICV. These results demonstrate that peripheral and central H3 receptors for histamine have a role in drinking elicited by eating and the postprandial gastrointestinal osmotic consequences of eating. These findings extend the evidence demonstrating a histaminergic contribution to food-related drinking in rats.

Drinking and unemployment: contrasting patterns among men and women.

Research on unemployment has paid only little attention to drinking and drinking problems. From the 1970s onwards the association of drinking and unemployment has come under systematic study. Contrasting tendencies emerge from this research. This paper distinguishes three instances of drinking and drinking problems and examines their association with employment status, i.e., (i) frequency of drinking, (ii) frequency of intoxication, and (iii) frequency of health problems due to drinking. A panel survey was conducted in 1983-1984, consisting of a sample of Finnish men and women, originally jobseekers in industry. Prevalence data and results of logistic regression analyses on the association of the three instances of drinking and drinking problems with employment status are presented. The frequency of drinking was unassociated with employment status for men and women at either of the two measurement points. Neither did the frequency of intoxication show any clear association with employment status. In contrast, the frequency of health problems due to drinking was associated in a statistically significant way with unemployment among men. Among women the association was rather the opposite, but it was not statistically significant. The paper concludes that it is important to distinguish between overall drinking and drinking problems, and between the determinants of male and female drinking problems. It is likely that selective processes at the labour market as well as social causation during unemployment lie behind the observed association of male unemployment and drinking problems.
