Malt liquor use, heavy/problem drinking and other problem behaviors in a sample of community college students.

OBJECTIVE: This study examined the prevalence of malt liquor use and its relationship with heavy or problem drinking, other substance use and other problem behaviors in a sample of 1,029 (58% female) students attending a community college in California. METHOD: Data were collected using anonymous surveys that were administered during daytime classes. Bivariate analyses were conducted to examine relationships between malt liquor use and demographic characteristics, heavy/problem drinking and other types of substance use and problem behaviors. Logistic regression analyses also were conducted to determine whether malt liquor use was predictive of problem drinking, drug use and other problem behavior after adjusting for background variables. RESULTS: Malt liquor use was most prevalent among male, white and Latino students. Compared with nonmalt liquor drinkers, malt liquor drinkers consumed significantly more alcohol, engaged in heavy drinking more often and experienced intoxication more often. Malt liquor drinkers scored significantly higher on the Alcohol Use Disorders Identification Test than nonmalt liquor drinkers. Malt liquor drinkers were more likely than nonmalt liquor drinkers and abstainers to report use of cigarettes, marijuana and illicit drugs and to exhibit problem behaviors. Malt liquor use was predictive of problem drinking, drug use and other problem behavior after adjusting for demographics and alcohol use in regression analyses. CONCLUSIONS: The findings of this study suggest that malt liquor use is associated with heavy and problem drinking, other drug use and behavioral problems among community college students.

College student protective strategies and drinking consequences.

OBJECTIVE: This study explored the relationships between college student gender, alcohol use, protective strategies and harmful drinking consequences. METHOD: A derivation sample (N = 3,851; 54% women) and a replication sample (N = 4,151; 55% women) of undergraduate students completed the Campus Alcohol Survey (CAS) in classroom settings. RESULTS: Although women drank less than men and were less likely to experience harmful consequences, they were more likely to use protective strategies. Hierarchical regression analyses revealed that students who consumed at least six drinks when they partied--especially men-were less likely to experience more common consequences (e.g., poor academic performance, property damage, unconsciousness, riding in a vehicle with others who have been drinking) if they engaged in self-protective strategies. Such strategies also helped students who exceeded the median number of drinks to moderate the effect of drinking on less common consequences (e.g., vehicular accidents, class failure, conflicts with authorities). CONCLUSIONS: These findings add to the growing literature on contextual events that protect students from harm while drinking.

Hazardous drinking and relationship violence perpetration and victimization in women arrested for domestic violence.

OBJECTIVE: Research has shown that women who perpetrate partner violence or are victims of partner violence are more likely than comparison groups to have alcohol problems. The present study represents the largest sample collected to date of women arrested for domestic violence and court referred to batterer intervention programs. The aim of this study is to compare hazardous and nonhazardous drinking women on violence perpetration and victimization and to examine whether group differences in these variables are attributable to women's drinking, their general propensity for violence, their partners' drinking, or a combination of these factors. METHODS: We recruited 103 women who were arrested for domestic violence and divided the sample into groups of hazardous drinkers (HD) and nonhazardous drinkers (NHD). We administered multiple measures of substance use and problems and assessed the women's relationship aggression, use of general violence and their relationship partners' substance use. RESULTS: Relative to the NHD group, the HD group scored higher on violence perpetration (physical assault, psychological abuse, sexual abuse, injuries) and violence victimization (physical assault). In addition, the HD group scored higher than the NHD group on general violence perpetration and partner alcohol and drug problems. Results from regression analyses indicated that women's drinking, women's general violence, and partner drinking all contributed to some form of violence perpetration or victimization; women's hazardous drinking group status was particularly important in the prediction of physical assault perpetration and victimization. CONCLUSIONS: The results of the study suggest that substance use and problems should be assessed routinely as part of violence intervention programs for women and that intervention programs would be improved by offering adjunct or integrated alcohol treatment.

Coping motives as a moderator of daily mood-drinking covariation.

OBJECTIVE: The current study examines the extent to which college students' reports of drinking to cope (DTC) with negative affect moderate the daily covariation between specific types of negative mood (sadness, fear, hostility, shyness and boredom) and alcohol use. METHOD: Participants were full-time college students, aged 18-20, attending a large Southeastern university (N = 72; 50% male). These individuals completed an experience-sampling protocol over a 1-month interval, to assess daily mood and alcohol use. RESULTS: A series of Hierarchical General Linear Models found that individuals who reported low motives to cope through drinking showed an expected absence of daily mood and drinking covariation. For those reporting high coping motives, a complex and somewhat counterintuitive series of findings were found; students high in DTC drank less on days in which they experienced greater sadness. Analyses on the quadratic effects of mood revealed that when experiencing moderate to high levels of fear and shyness, individuals high in DTC were more likely to drink. For those low in coping motivations, fear and shyness did not predict daily drinking. CONCLUSIONS: Findings highlight the need to better our understanding of the exact meaning of DTC measures. In addition, there is a need to study how the context of college drinking influences self-medication and students' self-reports of DTC.

Latent growth curve analyses of parent influences on drinking progression among early adolescents.

OBJECTIVE: The nature of parent influences on early adolescent substance use was examined. METHOD: Latent growth curve analyses were used to examine data on a sample of 2,453 adolescents from seven middle schools who were randomized to a problem behavior prevention program or a control condition and were assessed a total of five times during sixth to ninth grade. RESULTS: Whereas the growth in the number of friends who drink was positively associated with adolescent drinking, parental involvement, monitoring and expectations over time provided direct protective effects against drinking progression and indirect effects by limiting increases in the number of friends who drink. CONCLUSIONS: The results provide evidence in a sample of early adolescents that parenting behavior--including involvement, monitoring and expectations--protected against progression in drinking directly as well as indirectly by limiting growth in the number of friends who drink.

Heavy episodic drinking in the São Paulo epidemiologic catchment area study in Brazil: gender and sociodemographic correlates.

OBJECTIVE: The aims of this study were to quantify heavy episodic drinking (HED) among adults living in two middle-class boroughs in the city of São Paulo, Brazil, and to estimate possible effects of gender, age, and other sociodemographic factors. METHOD: Data were taken from the São Paulo Catchment Area Study. A representative sample (N = 1,464) of the adult population living in households was assessed through Composite International Diagnostic Interview Version 1.1. The pattern of lifetime and last-12-month alcohol consumption was evaluated. HED was defined as consuming five or more drinks per drinking day for men and four or more drinks per drinking day for women. Prevalence rates and sociodemographic correlates were examined separately for men and women. RESULTS: The overall 12-month prevalence of HED in this sample was 10.7%, with 15.4% of the men and 7.2% of the women reporting HED. Lifetime overall abstinence was 22.2%, with 32.4% of the women and 8.7% of the men being lifetime abstainers. The odds of HED among women were increased for those between 18 and 44 years of age and for those who were not married (separated, divorced, widowed, and never married). Among men the risk was increased for those between 18 and 24 years of age. CONCLUSIONS: HED is a common pattern of drinking in this sample, mainly in young men. Among women, HED is not confined to the younger groups. Future studies are needed to assess the impact of HED on physical health, mental health, and social functioning.

Parental rules and monitoring of children's movie viewing associated with children's risk for smoking and drinking.

OBJECTIVES: Evidence suggests that media portrayals of tobacco and alcohol use are important predictors of adolescent smoking and drinking. We examined the role of parents in monitoring and limiting children's movie exposure and whether or not this was associated with a lower risk of adolescent smoking and drinking. DESIGN: We surveyed 2606 child-parent dyads between 2002 and 2003. We asked children (9-12 years of age) how often their parents engaged in specific behaviors to monitor their movie viewing and if their parents allowed them to watch R-rated movies. We also surveyed children about parental monitoring of nonmedia-related behaviors. The primary outcomes were risk of smoking and drinking alcohol, defined by attitudinal susceptibility or early experimentation with either substance. RESULTS: Less than half (45.0%) the children were prohibited from watching R-rated movies. Of those who were allowed to watch R-rated movies, one third (34.7%) always viewed them with a parent and two thirds (65.3%) sometimes watched them without a parent. Less than 10% of the children reported that their parents consistently engaged in all 4 movie-monitoring behaviors. Even after controlling for parental monitoring of nonmedia-related behaviors and other covariates, children were at lower risk of smoking and drinking if their parents prohibited them from watching R-rated movies. Parental coviewing of R-rated movies was associated with a lower risk of child smoking but not drinking if parents consistently monitored what their children watched. CONCLUSIONS: Parental rules and monitoring of children's movie viewing may have a protective influence on children's risk for smoking and drinking, over and above parental monitoring of nonmedia related behaviors. This highlights a potential role for parents in preventing early initiation of tobacco and alcohol use among adolescents.

Alcohol drinking patterns by gender, ethnicity, and social class in Bahia, Brazil.

OBJECTIVE: To study patterns of alcohol consumption and prevalence of high-risk drinking. METHODS: A household survey was carried out in a sample of 2,302 adults in Salvador, Brazil. Cases of High-Risk Drinking (HRD) were defined as those subjects who referred daily or weekly binge drinking plus episodes of drunkenness and those who reported any use of alcoholic beverages but with frequent drunkenness (at least once a week). RESULTS: Fifty-six per cent of the sample acknowledged drinking alcoholic beverages. Overall consumption was significantly related with gender (male), marital status (single), migration (non-migrant), better educated (college level), and social class (upper). No significant differences were found regarding ethnicity, except for cachaça (Brazilian sugarcane liquor) and other distilled beverages. Overall 12-month prevalence of high-risk drinking was 7%, six times more prevalent among males than females (almost 13% compared to 2.4%). A positive association of HRD prevalence with education and social class was found. No overall relationship was found between ethnicity and HRD. Male gender and higher socioeconomic status were associated with increased odds of HRD. Two-way stratified analyses yielded consistent gender effects throughout all strata of independent variables. CONCLUSIONS: The findings suggest that social and cultural elements determine local patterns of alcohol-drinking behavior. Additional research on long-term and differential effects of gender, ethnicity, and social class on alcohol use and misuse is needed in order to explain their role as sources of social health inequities.

Effect of drinking water chlorination on Campylobacter spp. colonization of broilers.

The main source for Campylobacter spp. transmission from the environment to broiler chickens is still unclear. One implicated reservoir for the organism has been untreated broiler drinking water. This study was conducted with broilers first using experimental conditions (isolation units) and second under commercial conditions. We compared the rate of intestinal colonization in chickens provided 2 to 5 parts per million (ppm) chlorinated drinking water in relation to the frequency of colonization in chickens given unsupplemented drinking water. No significant difference (P > 0.05) was detected in isolation frequency or level of Campylobacter spp. colonization in birds provided chlorinated drinking water and control birds provided water without supplemental chlorine. In the isolation unit experiments, 86.3% (69/80) of the control and 85.0% (68/80) of the treated birds were colonized at levels corresponding to an average of 10(5.2) and 10(5.1) log colony-forming units (cfu) Campylobacter spp./g of cecal contents, respectively. Additionally, two sets of paired 20,000 bird broiler houses, with and without chlorination (2-5 ppm chlorine), were monitored in a commercial field trial. Effectiveness of chlorination was judged by prevalence of Campylobacter spp. in fecal droppings (960 samples) taken from the flocks in treated and control houses. Birds from the control houses were 35.5% (175/493) Campylobacter spp. positive, while 45.8% (214/467) of the samples from the houses having chlorinated drinking water yielded the organism. Chlorination of flock drinking water at the levels tested in this study was not effective in decreasing colonization by Campylobacter spp. under commercial production practices presently used in the United States.

Adolescent victimization and problem drinking.

This study explores the connection between violent victimization in adolescence and subsequent problem drinking. Using national data we estimate the effects of adolescent victimization on a 3-category problem drinking measure (Abstainers, Moderate, and Binge Drinkers). We also examine the differences in the social and personal consequences of drinking across victims and non-victims. These consequences include harm to friendships, health, outlook on life, marriage, work, studies, and financial position. Victims of adolescent violence are more likely to engage in subsequent binge drinking and experience negative drinking consequences, particularly negative financial consequences. The findings are consistent with the adolescent development literature, which has highlighted the importance of violent victimization in the transition to adult roles and responsibilities. Additional research, particularly longitudinal data on violent victimization and substance abuse on a nationally representative sample of young people and adults is needed to further explore the connection between violent victimization and subsequent problem drinking.

The role of coping and problem drinking in men's abuse of female partners: test of a path model.

This article examines the relationship of coping and problem drinking to men's abusive behavior towards female partners. While previous research has demonstrated a consistent association between problem drinking and male abuse of intimate partners, virtually no studies have assessed the role of coping in relation to men's violence. Furthermore, multivariate studies have not examined how these factors operate together to increase risk for abusive behavior. An ethnically diverse sample of 147 men in a court-mandated program for domestic violence offenders completed questionnaires at the first session. Path modeling was conducted to test the extent to which coping and problem drinking predicted both physical and psychological abuse. In addition, the relationships of problem drinking and physical abuse to injury of the men's female partners were examined. Results indicated that both the use of avoidance and problem-solving coping to deal with relationship problems were related indirectly to abusive behavior through problem drinking. Greater use of avoidance coping strategies was more likely among problem drinkers. By contrast, men who used higher levels of problem-solving coping were less likely to be problem drinkers. Avoidance, but not problem-solving coping also was directly and positively related to physical and psychological abuse. Men identified as problem drinkers were more likely to use both physical and psychological abuse. Finally, greater use of physical violence was strongly related to higher levels of injury among female partners, and served to mediate the relationship between problem drinking and injury. Results are discussed in terms of their contribution to the identification of risk and protective factors for men's violent behavior toward intimate female partners and implications for developing intervention strategies.

Human coffee drinking: manipulation of concentration and caffeine dose.

In a residential research ward coffee drinking was studied in 9 volunteer human subjects with histories of heavy coffee drinking. A series of five experiments was undertaken to characterize adlibitum coffee consumption and to investigate the effects of manipulating coffee concentration, caffeine dose per cup, and caffeine preloads prior to coffee drinking. Manipulations were double-blind and scheduled in randomized sequences across days. When cups of coffee were freely available, coffee drinking tended to be rather regularly spaced during the day with intercup intervals becoming progressively longer throughout the day; experimental manipulations showed that this lengthening of intercup intervals was not due to accumulating caffeine levels. Number of cups of coffee consumed was an inverted U-shaped function of both coffee concentration and caffeine dose per cup; however, coffee-concentration and dose-per-cup manipulations did not produce similar effects on other measures of coffee drinking (intercup interval, time to drink a cup, within-day distribution of cups). Caffeine preload produced dose-related decreases in number of cups consumed. As a whole, these experiments provide some limited evidence for both the suppressive and the reinforcing effects of caffeine on coffee consumption. Examination of total daily coffee and caffeine intake across experiments, however, provides no evidence for precise regulation (i.e., titration) of coffee or caffeine intake.

Drinking in a patchy environment: the effect of the price of water.

Rats in a laboratory foraging paradigm searched for sequential opportunities to drink in two water patches that differed in the bar-press price of each "sip" (20 licks) of water within a bout of drinking (Experiment 1) or the price and size (10, 20, or 40 licks) of each sip (Experiment 2). Total daily water intake was not affected by these variables. The rats responded faster at the patch where water was more costly. However, they accepted fewer opportunities to drink, and thus had fewer drinking bouts, and drinking bouts were smaller at the more costly patch than at the other patch. This resulted in the rats consuming a smaller proportion of their daily water from the more costly patch. The size of the differences in bout frequency and size between the patches appears to be based on the relative cost of water at the patches. The profitability of each patch was calculated in terms of the return (in milliliters) on either effort (bar presses) or time spent there. Although both measures were correlated with the relative total intake, bout size, and acceptance of opportunities at each patch, the time-based profitability was the better predictor of these intake measures. The rats did not minimize bar-press output; however, their choice between the patches and their bout sizes within patches varied in a way that reduced costs compared to what would have been expended drinking randomly. These data accord well with similar findings for choices among patches of food, suggesting that foraging for water and food occurs on the basis of comparable benefit-cost functions: In each case, the amount consumed is related to the time spent consuming.

Parental and school correlates of binge drinking among middle school students.

OBJECTIVES: We examined the prevalence and dynamics of binge drinking among middle school students. METHODS: We analyzed data from the National Longitudinal Study of Adolescent Health. The sample was composed of approximately 5300 seventh-and eighth-grade students who were interviewed at 2 points in time. RESULTS: Approximately 8% of seventh graders and 17% of eighth graders reported engaging in binge drinking during the past 12 months. These rates varied as a function of school characteristics. Low scores on the parenting variables-communication quality, use of reasoning, and control and supervision-and binge drinking during middle school also were predictive of binge drinking during high school. CONCLUSIONS: Binge drinking among middle school students is an important phenomenon that for many students forecasts future binge drinking during high school.

Aging and generational effects on drinking behaviors in men: results from the normative aging study.

The effects of aging on alcohol consumption behaviors are unclear because of confounding with period and cohort effects. In 1973, 1,859 male participants in the Normative Aging Study, born between 1892 and 1945, described their drinking behaviors by responding to a mailed questionnaire. In 1982, 1,713 of the participants in this study responded to a similar questionnaire. We used multivariate techniques, adjusting regression coefficients for the correlations between repeated responses of the same individuals, to assess the effects of birth cohort and aging on mean alcohol consumption level, on the prevalence of problems with drinking, and on the prevalence of averaging three or more drinks per day. Older men drank significantly less than younger men at both times yet there was no tendency for men to decrease their consumption levels over time. Each successively older birth cohort had a prevalence of problems with drinking estimated to be 0.037 lower than the prevalence of the next youngest cohort (95 per cent confidence interval: 0.029-0.045), yet there was no decrease in drinking problems over nine years. Interpretation of these findings requires consideration of the changes in attitudes as well as the increases in per capita consumption occurring in the United States throughout the 1970s. Results suggest that aging is not as important a factor in changes in drinking behaviors as generational or attitudinal changes.

Television beer advertising and drinking knowledge, beliefs, and intentions among schoolchildren.

OBJECTIVES: The relationships between television beer advertising and drinking knowledge, beliefs, and intentions were investigated in a survey of schoolchildren. The research was guided by a theoretical model specifying that awareness of advertising, and not mere exposure, is necessary for it to have an effect on beliefs or behaviors. METHODS: Participants were a random sample of 468 fifth- and sixth-grade schoolchildren from a northern California community. Data were collected in the home with a combination of self-administered questionnaires and structured interviews. RESULTS: Nonrecursive statistical modeling indicated that awareness of television beer advertising was related to more favorable beliefs about drinking, to greater knowledge of beer brands and slogans, and to increased intentions to drink as an adult. The effects of advertising awareness on knowledge, beliefs, and intentions were maintained when the reciprocal effects of beliefs, knowledge, and intentions on awareness were controlled. CONCLUSIONS: The findings suggest that alcohol advertising may predispose young people to drinking. As a result, efforts to prevent drinking and drinking problems among young people should give attention to countering the potential effects of alcohol advertising.

Patterns of alcohol use and the risk of drinking and driving among US high school students.

Approximately one third of deaths among persons aged 15 to 24 years are the result of motor vehicle-related crashes. Data from a national sample of US high school students were used to assess patterns of alcohol use among adolescents in relation to the risk of drinking and driving. Prevalence and odds ratios were calculated for drinking and driving associated with patterns of alcohol use. Drinking and driving increased with increasing frequency of alcohol use and binge drinking and when alcohol was used in addition to other drugs. Efforts to reduce drinking and driving among adolescents should address underage drinking that is frequent or heavy.

Drinking and driving among US high school seniors, 1984-1997.

OBJECTIVES: This article reports the prevalence of, and trends in, driving after drinking and riding in a car with a driver who has been drinking among American high school seniors, based on data from more than a decade (1984-1997) of annual national surveys. METHODS: Logistic regressions were used to assess the effects of demographic factors (gender, region of country, population density, parental education, and race/ethnicity) and selected "lifestyle" factors (religious commitment, high school grades, truancy, illicit drug use, evenings out per week, and miles driven per week). RESULTS: Rates of adolescent driving after drinking and riding with a driver who had been drinking declined significantly from the mid-1980s to the early or mid-1990s, but the declines have not continued in recent years. Rates of driving or riding after drinking were higher among high school seniors who are male. White, living in the western and northeastern regions of the United States, and living in rural areas. Truancy, number of evenings out, and illicit drug use all related significantly positively with the dependent variables, whereas grade point average and religious commitment had a negative relationship. Miles driven per week related positively to driving after drinking.
