    Background Non-daily smoking and heavy alcohol use are prevalent behaviors among young adults, with non-daily smoking occurring primarily in the context of alcohol use. Although the relationship between drinking and daily smoking has been well characterized in young adults, few epidemiological investigations have investigated the association between non-daily smoking and drinking behavior. Methods We examined Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; Grant et al., 2003; n=43,093). Young adults (age 18-25; n=5,838) were stratified on current smoking behavior (daily, non-daily, and non-smokers in the past 12 months) and differences in weekly quantity of alcohol use, frequency of alcohol use, frequency of binge drinking behavior, rates of NIAAA-defined hazardous drinking, and rates of DSM-IV alcohol diagnoses were investigated. College student status was examined. Results 25% were current smokers and 7% were smoking on a non-daily basis. 71% were current drinkers, 39% reported binge drinking at least once a month, 41% met criteria for hazardous drinking, and 18% had alcohol use disorders. Across all measures of alcohol use there was a significant effect of smoking status, with daily smokers having greater alcohol use patterns, compared to non-daily smokers, with non-smokers consuming the least. Non-daily smokers were more likely to report any binge drinking in the past 12 months. However, daily smokers were more likely to report daily binge drinking. With regard to hazardous drinking and alcohol use disorders, non-daily smoking conferred the greatest risk, followed by daily smoking with non-smoking as the reference group. Multinomial logistic regression demonstrated the odds of being a hazardous drinker were 16 times greater (95% CI 9.46 — 26.48) in a non-daily smoker compared to a non-smoker, whereas the odds for a daily smoker were increased by 7-fold (95% CI 5.54 — 9.36). A similar pattern of results was demonstrated

    Objectives To explore associations between subjective social status (SSS) and smoking level among 2274 adult current smokers. Methods Associations were investigated using a covariate-adjusted proportional odds cumulative logit model. Moderation (via race/ethnicity or sex) and mediation (via depressive symptoms, social/emotional support, or life satisfaction) were explored in additional models. Results Higher SSS was associated with greater likelihood of nondaily versus light daily or moderate/ heavy daily smoking (p = .017). Life satisfaction partially mediated the association of SSS and smoking level (p = .003). Conclusions Higher SSS was associated with greater likelihood of nondaily relative to light daily or moderate to heavy smoking, potentially via greater life satisfaction. Additional studies are needed to confirm these findings. PMID:24629553

    Russian levels of alcohol consumption and suicide are among the highest in the world. While observers have long suspected an association between the two, they were unable to investigate this hypothesis until recently due to past Soviet secrecy and thus a lack of data. This study took advantage of the newly available data during the post-Soviet era to examine the cross-sectional association between heavy drinking and suicide mortality in Russia. Aggregate mortality data for the Russian regions (n = 78) for the year 2000 were used to measure heavy drinking and suicide rates. Government data were used to control for the regional economic situation and strength of social institutions. Ordinary Least Squares regression was employed to estimate the effect of a proxy for heavy drinking on overall and sex-specific age-adjusted suicide rates. The results showed a positive and significant association between the two, and the association held for overall, male and female rates. These results not only confirmed an association between heavy drinking and suicide in Russia, but when compared to findings from previous studies of other countries they led to the hypothesis that a nation’s beverage preference may be as important as its wet/dry drinking culture in its sensitivity of suicide rates to alcohol consumption.

    Background Heavy alcohol use during adolescence may alter the trajectory of normal brain development. Whether developmental trajectories of regional cortical volume and white matter structures are differentially affected in heavy drinkers relative to non-drinking controls has not been studied over extended periods or with sample sizes adequate to address potential sex differences. Methods This longitudinal study examined gray and white matter volume trajectories in 134 adolescents (75 who transitioned into heavy drinking and 59 who remained light to non-drinkers over roughly 3.5 years). Each underwent magnetic resonance imaging (MRI) on a 3T system two to six times (390 total scans) between ages 12 to 24 and was followed up to 8 years. Volumes of neocortex, allocortex, and white matter structures were measured using atlas-based parcellation with longitudinal registration. Linear mixed-effects models described differences in trajectories of drinkers and controls over age; secondary analyses considered the contribution of other drug use to identified alcohol use effects. Results Heavy-drinking adolescents showed accelerated gray matter reduction in cortical lateral frontal and temporal volumes and attenuated white matter growth of the corpus callosum and pons relative to controls. These results were essentially the same when marijuana and other drug use were examined. Male and female drinkers showed similar patterns of development trajectory abnormalities. Discussion Longitudinal analysis enabled detection of accelerated typical volume decline in frontal and temporal cortical volumes and attenuated growth in principal white matter structures in adolescents who started to drink heavily. These results provide a call for caution regarding heavy alcohol use during adolescence, whether heavy alcohol drinking is the cause or one of many factors in a constellation of causes of these alterations in brain development.

  6. Relations between heavy drinking, gender, and substance-free reinforcement.

    Behavioral economic theory and laboratory research have suggested that substance abuse may be associated with diminished engagement in enjoyable substance-free activities (substance-free reinforcement). However, college students, in particular men, have reported numerous social benefits from drinking that might mitigate the expected inverse relation between drinking and substance-free reinforcement. In this study, we examined the relations between college student heavy drinking, gender, and several categories of substance-free reinforcement (peer, dating, sexual, school, and family activities). Participants were 246 undergraduate students who were classified as a function of their reported frequency of heavy drinking during a typical week in the past month (120 heavy drinkers, 126 light drinkers). Heavy drinking was associated with significantly higher substance-free peer and sexual reinforcement. This association was gender invariant and remained significant in multiple regression models that controlled for gender, ethnicity, and fraternity or sorority membership. Substance-free reinforcement did not predict frequency of heavy drinking in models that included levels of substance-related reinforcement. The results indicate that college student heavy drinking is not associated with global deficits in substance-free reinforcement and is instead associated with increased peer and sexual activity that occurs outside the context of drinking or drug use. Prevention programs should help students to compensate for the potential loss of social reinforcement associated with reductions in drinking.

    Objective: This investigation examined patterns of heavy drinking among Black and White young adults from a person-centered perspective and linked family and individual factors in adolescence to young adult drinking patterns. Method: The analysis focuses on 331 10th-grade students (168 Whites, 163 Blacks; 51% males) who were followed into young adulthood (ages 20 and 22). Cluster analyses using heavy episodic drinking, drunkenness, and alcohol problems in young adulthood resulted in groups of drinkers with different patterns. Groups were examined across and within race. Associations between young adult drinking groups and adolescent family and individual factors were tested. Results: Groups followed well-established race differences, with Whites clustering into frequent drinking groups more than Blacks, and Blacks clustering into non–heavy drinking groups more than Whites. Further, Black heavy drinkers reported fewer alcohol problems than White counterparts. Parental monitoring, consistent discipline, ethnic identity, and delinquency were associated with adult heavy episodic drinking groups for both races. Monitoring and delinquency, along with parental norms, were associated with drunkenness groups for both races. However, race differences were observed for drunkenness clusters such that attachment was predictive for White clusters, and parental guidelines and discipline were predictive for Black clusters. Conclusions: Large race differences in heavy drinking at young adulthood were confirmed. Family dynamics in 10th grade were identified as important for the development of different drinking patterns in the early 20s, when many individuals have left home, which suggests a key target for substance use prevention programs.

    The recent Amethyst Initiative argues that a minimum legal drinking age (MLDA) of 21 has created a culture of heavy alcohol use on college campuses by making drinking clandestine and extreme. This group and others argue that lowering the MLDA will reduce the problem of "binge drinking" on college campuses. However, such a policy change would…

  9. Drinking identity as a mediator of the relationship between drinking motives and weekly alcohol consumption among heavy drinking undergraduate students

    2014-01-01

    Objectives The present study assessed relationships among social, coping, enhancement, and conformity drinking motives and weekly alcohol consumption by considering drinking identity as a mediator of this relationship. Methods Participants were 260 heavy drinking undergraduate students (81% female; Mage = 23.45; SD = 5.39) who completed a web-based survey. Results Consistent with expectations, findings revealed significant direct effects of motives on drinking identity for all four models. Further, significant direct effects emerged for drinking identity on weekly drinking. Results partially supported predictions that motives would have direct effects on drinks per week; total effects of motives on drinking emerged for all models but direct effects of motives on weekly drinking emerged for only enhancement motives. There were significant indirect effects of motives on weekly drinking through drinking identity for all four models. Conclusions Findings supported hypotheses that drinking identity would mediate the relationship between drinking motives and alcohol consumption. These examinations have practical utility and may inform development and implementation of interventions and programs targeting alcohol misuse among heavy drinking undergraduate students.

    2013-01-01

    This study investigates the relationship between the level of acculturation and acculturation stress and the extent to which each predicts problems related to drinking. Hispanics who met criteria for hazardous drinking completed measures of acculturation, acculturation stress, and drinking problems. Sequential multiple regression was used to determine whether the levels of self-reported acculturation stress predicted concurrent alcohol problems after controlling for the predictive value of the acculturation level. Acculturation stress accounted for a significant variance in drinking problems, while adjusting for acculturation, income, and education. Choosing to drink in response to acculturation stress should be an intervention target with Hispanic heavy drinkers.

  13. Predictors of heavy drinking and drinking problems over the first 4 years of marriage.

    2008-03-01

    This study investigated the factors predictive of heavy drinking and drinking problems over the early years of marriage, focusing on premarital drinking and the relatively stable individual risk and protective factors that were present prior to marriage and on social-interpersonal factors that may change or emerge over marriage. Newlywed couples were assessed at the time of marriage and at the 1st, 2nd, and 4th anniversaries with respect to frequency of heavy drinking and the extent of drinking problems and a variety of factors that have been found to be predictive of adult alcohol problems. The results indicated that antisocial characteristics, family history of alcoholism, negative affect, and alcohol expectancies were related to heavy drinking and alcohol problems at the time of marriage. Changes after marriage were predicted by the drinking of one's partner and of one's peers and by alcohol expectancies for social/physical pleasure for both men and women. In addition, the quality of the marriage was longitudinally protective from the experience of alcohol problems for both men and women, although it was not related to changes in heavy drinking.

  14. Heavy Drinking Relates to Positive Valence Ratings of Alcohol Cues

    2009-01-01

    Background A positive family history of alcohol use disorders (FH) is a robust predictor of personal alcohol abuse and dependence. Exposure to problem-drinking models is one mechanism through which family history influences alcohol-related cognitions and drinking patterns. Similarly, exposure to alcohol advertisements is associated with alcohol involvement and the relationship between affective response to alcohol cues and drinking behavior has not been well established. In addition, the collective contribution that FH, exposure to different types of problem-drinking models (e.g., parents, peers), and personal alcohol use have on appraisal of alcohol-related stimuli has not been evaluated with a large sample. Objective We investigated the independent effects of FH, exposure to problem-drinking models, and personal alcohol use on valence ratings of alcohol pictures in a college sample. Method College students (N=227) completed measures of personal drinking and substance use, exposure to problem-drinking models, FH, and ratings on affective valence of 60 alcohol pictures. Results Greater exposure to non-familial problem-drinkers predicted greater drinking among college students (β = .17, p < .01). However, personal drinking was the only predictor of valence ratings of alcohol pictures (β= −.53, p < .001). Conclusions Personal drinking level predicted valence ratings of alcohol cues over and above FH, exposure to problem-drinking models, and demographic characteristics. This suggests that positive affective responses to alcohol pictures are more a function of personal experience (i.e., repeated heavy alcohol use) than vicarious learning. PMID:18855802

    Heavy drinking has increased in recent years and has been linked to numerous health-related risks, particularly in women. A number of factors may play a role in exacerbating the risks linked to heavy drinking, such as impulsivity, which itself is related to a number of risky behaviors. The present study investigated the effects of alcohol (0, 0.5, 0.75 g/kg) on impulsivity in female heavy drinkers (n = 23) and female light drinkers (n = 23) using a double-blind, placebo-controlled outpatient design; all women were tested during follicular phase of the menstrual cycle. Each session, participants completed a range of tasks including subjective measures of abuse liability, cognitive performance tasks, three behavioral impulsivity tasks, and a risk-taking task. Alcohol increased impulsivity on the Immediate and Delayed Memory Task (IMT and DMT) and Delay Discounting task. Heavy drinkers scored higher on impulsivity self-reports and were more impulsive on the IMT and the GoStop task than light drinkers. The high dose of alcohol further increased impulsive performance on the IMT and DMT in heavy drinkers. There were no group differences or alcohol effects on the Balloon Analogue Risk Task. Alcohol increased sedative-like effects more in light drinkers and increased stimulant-like effects and alcohol liking more in heavy drinkers. In summary, female heavy drinkers are less sensitive to the negative effects of alcohol, report more positive effects of alcohol, and are more impulsive than female light drinkers. Moreover, impulsive responding was exacerbated by alcohol drinking among female heavy drinkers, indicating that women who drink at this level are at increased risk for developing alcohol use disorders and engaging in other risky behaviors, particularly after drinking.

    Kranzler, Henry R.; Wetherill, Reagan; Feinn, Richard; Pond, Timothy; Gelernter, Joel; Covault, Jonathan

    2014-01-01

    Background We examined whether the effects of topiramate and a single nucleotide polymorphism (SNP; rs2832407) in GRIK1, which encodes a kainate receptor subunit, persisted following a 12-week, placebo-controlled trial in 138 heavy drinkers with a treatment goal of reduced drinking. During treatment, topiramate 200 mg/day significantly reduced heavy drinking days and increased the frequency of abstinent days (Kranzler et al. 2014a). In the European-American (EA) subsample (n=122), rs2832407 moderated the treatment effect on heavy drinking. Methods Patients were re-interviewed 3 and 6 months after the end of treatment. During treatment, we obtained 92.4% of drinking data, with 89.1% and 85.5% complete data at the 3- and 6-month follow-up visits, respectively. We examined four outcomes over time in the overall sample and the EA subsample: percent heavy drinking days (PHDD), percent days abstinent (PDA), serum γ-glutamyl transpeptidase (GGTP) concentration, and a measure of alcohol-related problems. Results In the full sample, the lower PHDD and higher PDA seen with topiramate treatment were no longer significant during follow-up. Nonetheless, the topiramate-treated patients had lower alcohol-related problem scores during treatment and both follow-up periods. Further, in the EA subsample, the greater reduction in PHDD seen during treatment in rs2832407*C-allele homozygotes persisted throughout follow-up, with no significant effects in A-allele carriers. A reduction in GGTP concentration was consistent with the reduction in heavy drinking, but did not reach statistical significance. Conclusion There are persistent therapeutic effects of topiramate in heavy drinkers, principally in rs2832407*C-allele homozygotes. PMID:25581656

    2015-01-01

    Adolescent heavy alcohol drinking increases the risk for alcohol use disorders in adulthood, yet mechanisms conferring increased risk are not well understood. We propose that adolescent alcohol drinking shapes alcohol’s aversive or appetitive properties in adulthood. Alcohol normally drives aversive learning and alcohol-predictive cues are avoided. We hypothesize that through adolescent heavy drinking alcohol gains access to appetitive learning. A primary consequence is that alcohol-predictive cues become valued and sought out. To test this hypothesis, we gave genetically heterogeneous, male Long Evans rats voluntary, chronic intermittent access to water or alcohol throughout adolescence and then identified moderate and heavy alcohol drinkers. After a short abstinence period, we assessed the aversive or appetitive properties of alcohol using flavor learning procedures. We compared alcohol to the known appetitive properties of sugar. Flavor learning in adult rats who were alcohol-naïve or adolescent moderate alcohol drinkers revealed alcohol to be aversive and sugar to be appetitive. The same flavor learning procedures revealed both alcohol and sugar to be appetitive in adult rats who were adolescent heavy drinkers. The results demonstrate that alcohol gains access to neurobehavioral circuits for appetitive learning through adolescent heavy alcohol drinking. PMID:26052793

    2011-01-01

    Objective: This article extends the compartmental model previously developed by Scribner et al. in the context of college drinking to a mathematical model of the consequences of lowering the legal drinking age. Method: Using data available from 32 U.S. campuses, the analyses separate underage and legal age drinking groups into an eight-compartment model with different alcohol availability (wetness) for the underage and legal age groups. The model evaluates the likelihood that underage students will incorrectly perceive normative drinking levels to be higher than they actually are (i.e., misperception) and adjust their drinking accordingly by varying the interaction between underage students in social and heavy episodic drinking compartments. Results: The results evaluate the total heavy episodic drinker population and its dependence on the difference in misperception, as well as its dependence on underage wetness, legal age wetness, and drinking age. Conclusions: Results suggest that an unrealistically extreme combination of high wetness and low enforcement would be needed for the policies related to lowering the drinking age to be effective.

    Background This research investigated the sensitivity and specificity of heavy and binge drinking for screening of alcohol use disorder. Methods This retrospective study was conducted with 976 adults who visited the Sun Health Screening Center for health screenings in 2015. Daily drinking amount, drinking frequency per week, and weekly drinking amount were investigated. Using criteria from the National Institute on Alcohol Abuse and Alcoholism, participants were classified as normal drinkers, heavy drinkers, or binge drinkers, and grouped by age and sex. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of heavy and binge drinking were compared for the diagnosis of alcohol abuse and alcohol dependence using the Diagnostic and Statistical Manual of Mental Disorders (DSM) 4th edition-text revision and alcohol use disorder using the DSM 5th edition. Results The sensitivity of heavy and binge drinking for the diagnosis of alcohol abuse, alcohol dependence, and alcohol use disorder were 51.7%, 43.8%, and 35.3%, and 69.0%, 62.5%, and 48.2%, respectively. The specificity of these were 90.1%, 91.7%, and 95.5%, and 84.3%, 86.8%, and 91.2%, respectively. The PPV of these were 24.8%, 40.5%, and 72.7%, and 21.7%, 38.0%, and 65.2%, respectively. The NPV of these were 96.7%, 92.6%, and 81.2%, and 97.8%, 94.7%, and 83.7%, respectively. Conclusion Heavy and binge drinking did not show enough diagnostic power to screen DSM alcohol use disorder although they did show high specificity and NPV. PMID:27468339

  4. Decisional balance: Alcohol decisional balance intervention for heavy drinking undergraduates

    PubMed Central

    2015-01-01

    Background This study evaluated a decisional balance intervention among heavy drinking undergraduates and compared a non-weighted decisional balance proportion (DBP; Collins, Carey, & Otto, 2009) to a participant-weighted DBP with weights based on relative importance of items. We expected: 1) the intervention to decrease drinking compared to control; 2) the weighted intervention to be more effective compared to the non-weighted or control in reducing drinking; and 3) intervention efficacy to be moderated by initial DBP. Method Participants (N =162, Mean age = 24.37, SD = 6.81, 27% male) were randomly assigned to an alcohol intervention wherein they were either asked to assign weights of importance to pros and cons (weighted intervention), or not (non-weighted intervention), or to control. Participants completed web-based questionnaires at baseline and again during a one month follow-up assessment. Results Consistent with expectations, the non-weighted intervention was associated with reduced follow-up weekly drinking, and the weighted intervention was associated with reductions in drinking frequency. Results further indicated that initial decisional balance did not moderate intervention efficacy. Discussion Findings suggest that the decisional balance procedure can reduce drinking but there was not compelling evidence for the addition of weights. This study lays the groundwork for enhancing future interventions by increasing empirical knowledge of the role motivation plays in heavy alcohol use. PMID:26555004

    2013-01-01

    We test whether heavy or binge drinkers are overly optimistic about probabilities of adverse consequences from these activities or are relatively accurate about these probabilities. Using data from a survey in eight cities, we evaluate the relationship between subjective beliefs and drinking. We assess accuracy of beliefs about several outcomes of heavy/binge drinking: reduced longevity, liver disease onset, link between alcohol consumption and Driving While Intoxicated (DWI), probability of an accident after drinking, accuracy of beliefs about encountering intoxicated drivers on the road, and legal consequences of DWI—ranging from being stopped to receiving fines and jail terms. Overall, there is no empirical support for the optimism bias hypothesis. We do find that persons consuming a lot of alcohol tend to be more overconfident about their driving abilities and ability to handle alcohol. However, such overconfidence does not translate into over-optimism about consequences of high levels of alcohol consumption. PMID:24058265

  7. Heavy drinking on college campuses: no reason to change minimum legal drinking age of 21.

    PubMed

    Saylor, Drew K

    2011-01-01

    The recent Amethyst Initiative argues that a minimum legal drinking age (MLDA) of 21 has created a culture of heavy alcohol use on college campuses by making drinking clandestine and extreme. This group and others argue that lowering the MLDA will reduce the problem of "binge drinking" on college campuses. However, such a policy change would remove one of the most researched and supported policies in the nation's alcohol control arsenal. There is little evidence that other interventions or policies are capable of working on the same broad level as MLDA 21, and there could also be a deleterious ripple effect in related legislation because MLDA 21 works in conjunction with other drinking laws. In addition, historic and international experiences with a lowered MLDA indicate there are serious social and public health consequences. Instead of removing efficacious interventions, we must remain committed to implementing and enforcing evidence-based practices and legislation.

    18 pregnant women identified as heavy drinkers by the criteria of Cahalan et al., gave birth to 6 normal infants, 5 infants with fetal alcohol syndrome (FAS) and 7 with partial FAS. Average daily alcohol consumption of mothers of normal infants was less than that of mothers of FAS and partial FAS infants. Lower socioeconomic class, higher parity and increased use of tobacco and other drugs were non-alcohol-related maternal factors which appeared to influence the outcome of pregnancy in heavy-drinking women.

    Few studies examining the link between personality and alcohol use have adopted a comprehensive modeling framework to take into account individuals’ profiles across multiple personality traits. In this study, latent profile analysis (LPA) was applied to a national sample of young adults in the United States to identify subgroups defined by their profiles of mean scores on the Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness personality factors. Personality profiles were then used to predict heavy drinking. Five profiles were identified: Reserved, Rigid, Confident, Ordinary, and Resilient. Compared to individuals in the Ordinary profile, those with Reserved and Resilient profiles were at increased risk of frequent heavy drinking. These findings suggest which comprehensive personality profiles may place individuals at risk for problematic alcohol-related outcomes. PMID:25892836

    Objective This study examined patterns of drinking motives endorsed by heavy drinking veterans who either did or did not meet criteria for posttraumatic stress disorder (PTSD). Method Data were collected from 69 veterans of Operations Enduring Freedom or Iraqi Freedom (OEF/OIF) who had screened positive for hazardous drinking. The sample was 91.3% male and 65.2% Caucasian. Based on a structured interview, 58% of the sample met criteria for PTSD. Results The PTSD group scored higher than the non-PTSD group on scales measuring drinking to cope with anxiety and depression and similarly to the non-PTSD group on scales measuring social, enhancement and conformity motives. Coping and social motives were significantly correlated with adverse alcohol consequences. Overall, the PTSD group showed stronger relations between coping scales and aspects of alcohol misuse, relative to the non- PTSD group. Conclusion These findings suggest first, that among heavy drinking OEF/OIF veterans there is a high base rate of PTSD. Second, coping motives are frequently reported in this population, and they seem to be related to a more severe pattern of alcohol-related consequences. These findings underscore the importance of assessing the interplay between PTSD and substance abuse in trauma-exposed samples.

    Introduction The present study investigated the rate and pattern of neuropsychological recovery in heavy episodic drinking teens during the initial days to weeks of abstinence from alcohol. Method Adolescents (ages 16–18) with histories of heavy episodic drinking (HED; N=39) and socio-demographically similar control teens (CON; N=26) were recruited from San Diego area schools. HED and CON were comparable on 5th grade standardized math and language arts test performance to ensure similar functioning prior to onset of substance use. Participants were administered three neuropsychological test batteries with 2-week intervals during a 4-week monitored abstinence period. Results HED teens performed worse overall than CON on tests of prospective memory (p=.005), cognitive switching (p=.039), inhibition task accuracy (p=.001), verbal memory (p's<.045), visuospatial construction (p’s<.043), and language and achievement (p’s<.008). The statistically significant group × time interaction for block design demonstrated normalization within the four weeks of abstinence for the HED (p=.009). Discussion This study identified cognitive performance deficits associated with heavy episodic drinking in adolescence during early abstinence and with sustained 4-week abstention. These findings suggest alcohol-related influences on several underlying brain systems that may predate the onset of alcohol abuse or dependence or take longer than four weeks to recover.

    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. PMID:17017304

    Few studies have examined correlates of heavy drinking among rural immigrant Latino men. This analysis identified correlates of typical week drunkenness and past 30-day heavy episodic drinking, within a sample of immigrant Latino men in rural North Carolina (n = 258). In the bivariate analyses, Mexican birth, entering the United States as an adult, and year-round employment were associated with increased odds of typical week drunkenness, and higher acculturation and affiliation with a religion with strict prohibitions against drinking alcohol were associated with lower odds of typical week drunkenness. Being older, Mexican birth, and entering the United States as an adult were associated with increased odds of heavy episodic drinking, and affiliation with a religion with strict prohibitions against drinking alcohol was associated with decreased odds of heavy episodic drinking. In multivariable modeling, only religious affiliation was associated with typical week drunkenness. Mexican birth, entering the United States as an adult and were associated with increased odds of heavy episodic drinking, and affiliation with a religion with strict prohibitions against drinking alcohol and completing high school was associated with lower odds of heavy episodic drinking. The health of minority men in the United States has been neglected, and immigrant Latino men comprise a particularly vulnerable population. This analysis provides initial data on some factors associated with heavy drinking within a population about whom little is known. Future studies should examine moderating or mediating factors between age, acculturation, religiosity, and heavy drinking that might be targets for behavioral interventions. PMID:24457467

    2014-01-01

    This study tested associations between positive and negative affect and heavy drinking in 734 college students who completed daily diaries in 14-day bursts once per semester over 7 semesters (≤98 days per person). Three-level multilevel models tested whether affect and heavy drinking were linked across days, semesters, and persons. Higher daily, between-semester, and between-person positive affect were each associated with a greater odds of heavy drinking on weekdays and on weekend days. A significant interaction with semester in college showed that the association between daily positive affect and heavy drinking on weekend days became stronger over time. That is, heavy drinking on a weekend day with higher positive affect was more likely in later years of college (OR=2.93, Fall of 4th year), compared to earlier in college (OR=1.80, Fall of 1st year). A similar interaction was found for between-semester positive affect and heavy drinking on weekdays. Higher daily negative affect was associated with a greater odds of heavy drinking on weekdays only for students who first began drinking in 7th grade or earlier (OR=2.36). Results of this study highlight the importance of varied time spans in studying the etiology, consequences, and prevention of heavy drinking. Harm-reduction strategies that target positive affect-related drinking by encouraging protective behaviors during celebratory events may become increasingly important as students transition to later years of college.

    Objective Hazardous alcohol use by HIV-infected women is associated with poor HIV outcomes and HIV transmission risk behaviors. We examined the effectiveness of brief alcohol intervention (BI) among hazardous drinking women receiving care in an urban, HIV clinic. Methods Women were randomized to a 2-session BI or usual care. Outcomes assessed at baseline, 3, 6 and 12 months included 90-day frequency of any alcohol use and heavy/binge drinking (≥4 drinks per occasion), and average drinks per drinking episode. Secondary outcomes included HIV medication and appointment adherence, HIV1-RNA suppression, and days of unprotected vaginal sex. We examined intervention effectiveness using generalized mixed effect models and quantile regression. Results Of 148 eligible women, 74 were randomized to each arm. In mixed effects models, 90-day drinking frequency decreased among intervention group compared to control, with women in the intervention condition less likely to have a drinking day (OR: 0.42 (95% CI: 0.23–0.75). Heavy/binge drinking days and drinks per drinking day did not differ significantly between groups. Quantile regression demonstrated a decrease in drinking frequency in the middle to upper ranges of the distribution of drinking days and heavy/binge drinking days that differed significantly between intervention and control conditions. At follow-up, the intervention group had significantly fewer episodes of unprotected vaginal sex. No intervention effects were observed for other outcomes. Conclusions Brief alcohol intervention reduces frequency of alcohol use and unprotected vaginal sex among HIV-infected women. More intensive services may be needed to lower drinks per drinking day and enhance care for more severely affected drinkers. PMID:25967270

    Alcohol can disrupt goal-directed behavior by impairing the ability to inhibit attentional shifts towards salient but goal-irrelevant stimuli. Individuals who are highly sensitive to this effect of the drug may be at increased risk for problematic drinking, especially among those whose attention is drawn to alcohol-related cues in the environment (i.e., attentional bias). The current study examined the acute impairing effect of alcohol on inhibitory mechanisms of attentional control in a group of healthy social drinkers. We then examined whether increased sensitivity to this disinhibiting effect of alcohol was associated with heavy drinking, especially among those who have an attentional bias towards alcohol-related stimuli. Eighty nondependent social drinkers performed a delayed ocular response task that measured their inhibitory control of attention by their ability to suppress attentional shifts to irrelevant stimuli. Attentional bias was measured using a visual probe task. Inhibitory control was assessed following a moderate dose of alcohol (0.64 g/kg) and a placebo. Participants made more inhibitory failures (i.e., premature saccades) following 0.64 g/kg alcohol compared with placebo and the relation of this effect to their drinking habits did depend on the level of the drinker’s attentional bias to alcohol-related stimuli. Among drinkers with higher attentional bias, greater impairment of inhibitory control was associated with heavier drinking. In contrast, drinkers with little or no attentional bias showed no relation between their sensitivity to the disinhibiting effects of alcohol and drinking habits. These findings have implications for understanding how heightened incentive-salience of alcohol cues and impaired attentional control can interactively contribute to excessive alcohol use.

    Objectives To explore demographics, contextual factors, and health risk behaviors associated with nondaily smoking by college students. Methods In fall 2005, a random sample of 4,100 students completed an online survey. Results 29% reported current smoking, of which 70% were nondaily smokers. Compared to daily smokers, nondaily smokers were younger, African American (compared to White), had mothers with higher education, belonged to Greek organizations, and attended private (vs. public) schools. Nondaily smokers were less likely to have used illicit drugs. Conclusions Nondaily and daily smokers differed on several demographic and contextual factors, but reported mostly similar health risk behaviors. PMID:22370259

    There is a high prevalence of comorbid tobacco use and alcohol use disorder (AUD), affecting more than 6 million people in the US. Globally, tobacco and alcohol use rank fourth and fifth, respectively, for disability-adjusted life-years lost. Levels of alcohol use are higher in smokers than nonsmokers, and the prevalence of smoking is higher in heavy drinkers compared with nondrinkers. This relationship is driven by many different factors, including genetics, neurobiological mechanisms, conditioning processes, and psychosocial influences. Although this unique population tends to experience more negative health consequences, more severe AUD, and poorer response to treatment than those with either AUD or tobacco use disorder alone, there are currently no available treatment protocols tailored to this comorbid condition. In this review, we provide a comprehensive review of ongoing clinical research into smoking cessation options for heavy-drinking smokers (HDS) through an evaluation of the effect of promising novel pharmacotherapies as well as combination therapies, including varenicline, naltrexone, the combination of varenicline and naltrexone, and the combination of naltrexone and nicotine replacement therapy (NRT). These treatments are considered in light of the standard of care for smoking cessation, and seek to improve upon the available guidelines for this sizeable subgroup of smokers, namely those smokers who drink heavily.

    Recent models of alcohol use in youth and young adulthood have incorporated personality change and maturation as causal factors underlying variability in developmental changes in heavy drinking. Whereas these models assume that personality affects alcohol use, the current prospective study tested the converse relation. That is, we tested whether, after accounting for the effect of traits on drinking, collegiate heavy drinking in turn predicted individual differences in change in alcohol-related aspects of personality. We also examined whether affiliation with heavy-drinking peers better accounted for this relation. Following a cohort of recent high school graduates (N = 1,434) through the college years, we found evidence for transactional relations between heavy drinking and changes in impulsivity and sensation seeking. Both traits predicted increases in heavy drinking, but more importantly, heavy drinking predicted increases in sensation seeking and impulsivity. In final models, social influences did not underlie the effect of heavy drinking on increases in sensation seeking and impulsivity. The results of this investigation suggest that collegiate heavy drinking may negatively and pervasively impact a wide range of behaviors because of its effect on personality change. PMID:21443288

    Heavy metals in drinking water pose a threat to human health. Populations are exposed to heavy metals primarily through water consumption, but few heavy metals can bioaccumulate in the human body (e.g., in lipids and the gastrointestinal system) and may induce cancer and other risks. To date, few thousand publications have reported various aspects of heavy metals in drinking water, including the types and quantities of metals in drinking water, their sources, factors affecting their concentrations at exposure points, human exposure, potential risks, and their removal from drinking water. Many developing countries are faced with the challenge of reducing human exposure to heavy metals, mainly due to their limited economic capacities to use advanced technologies for heavy metal removal. This paper aims to review the state of research on heavy metals in drinking water in developing countries; understand their types and variability, sources, exposure, possible health effects, and removal; and analyze the factors contributing to heavy metals in drinking water. This study identifies the current challenges in developing countries, and future research needs to reduce the levels of heavy metals in drinking water.

    Background Risks and potential benefits associated with alcohol use vary with the amount of alcohol consumed on a drinking occasion. Over time, changes in the absolute and relative numbers of light or heavy drinking episodes may occur, impacting health and social problems. Methods Analyses of the 2000, 2005 and 2010 NAS surveys focus on trends in the volumes of alcohol consumed on days where the drinker had 1–2, 3–4 or 5 or more drinks separately. These volume measures were obtained from graduated frequency questions with adjustments for estimated drink alcohol content for each drinker based on reported beer brand, spirits drink and pour method, contexts of drinking and demographic characteristics. Respondents with especially high alcohol content drinks were adjusted up one category and those with especially low alcohol content drinks were adjusted down one category. Trend significance was tested with adjusted Wald tests and in negative binomial models with 2000 as the reference year, indicators for race/ethnicity group and interactions between these and survey year, and adjustments for age, educational attainment, income, employment status and wetness region. Analyses were conducted both in the overall sample including abstainers, and in the current drinker sample only. Results Overall trend results indicate an increase in drink-alcohol-content-adjusted alcohol volume of 25% from 2000 to 2010 with similar changes between 2000 to 2005 and 2005 to 2010. Most of the increase from 2000 to 2005 resulted from increased volume from light (1–2 drink) days for men and women and moderate to heavy (3–4 drink) days for women, while the change from 2005 to 2010 resulted mostly from volume from heavy drinking days (5+ drinks per day) for men. Black and Hispanic women were found not to have participated in the overall trend of increased alcohol volume. Conclusions Findings highlight shifts in drinking patterns suggesting increased heavy occasion drinking in 2010

    Burke and Stephens (1999) [Burke, R.S., Stephens, R.S. Social anxiety and drinking in college students: A social cognitive theory analysis. Clinical Psychology Review, 19, (1999) 513-530.] proposed a social cognitive theory of heavy drinking in college students. According to this theory, alcohol expectancies for social facilitation and self-efficacy for refusing heavy drinking in anxiety-producing social situations moderate the relationship between social anxiety and drinking. In the current study, a significant three-way interaction was observed among social anxiety, expectancies, and self-efficacy when amount and frequency of drinking was the dependent variable. As predicted by the model, socially anxious college students with low self-efficacy for avoiding heavy drinking in social situations and high positive expectancies for social facilitation reported more alcohol consumption than other socially anxious individuals.

    This is the first randomized trial testing whether heavy drinking undergraduates mandated to the Brief Alcohol Screening and Intervention for College Students (BASICS) program following a campus alcohol violation would benefit as much as heavy drinking volunteers up to one year post-intervention using control groups with high-risk drinkers to model disciplinary-related and naturalistic changes in drinking. Participants (61% male; 51% mandated; 84% Caucasian; Mage = 20.14 years) were screened for heavy drinking and randomized to BASICS (n = 115) or assessment-only control (n = 110). Outcome measures (drinking, alcohol problems) were collected at baseline, 4 weeks, 3, 6, and 12 months post-intervention. At 4 weeks post-intervention, intent-to-treat multilevel longitudinal models showed that regardless of referral group (mandated or volunteer) BASICS significantly decreased weekly drinking, typical drinks, and peak drinks relative to controls (ds = .41-.92). BASICS had a large effect on decreases in alcohol problems (d = .87). At 12 months post-intervention, BASICS participants (regardless of referral group) reported significantly fewer alcohol problems (d = .56) compared to controls. Significant long-term intervention gains for peak and typical drinks were sustained in both referral groups relative to controls (ds = .42; .11). Referral group had no significant main effect and did not interact with intervention condition to predict outcomes. Given that BASICS was associated with less drinking and fewer alcohol problems (even among heavier drinking mandated students up to one year post-intervention), provision of BASICS-style programs within disciplinary settings may help reduce heavy and problematic drinking among at-risk students.

    Heavy drinking patterns during marriage can be problematic for both spouses and the relationship. Moreover, spouses use different strategies in an attempt to change their partner's drinking behavior, which can impact the relationship in different ways. The current research examined whether associations between heavy drinking and marital adjustment are mediated by partner regulation strategies (i.e., punishment and reward). Married couples (N=123 dyads) with at least one spouse who consumed alcohol regularly and at least one undergraduate spouse completed web-based assessments at baseline and three and six months later. Mediation hypotheses were tested using a repeated-measures version of the Actor-Partner Interdependence Model. As predicted, a significant partner effect emerged suggesting that heavy drinking was associated with greater use of punishment strategies, which were in turn associated with diminished satisfaction. Another significant partner effect revealed that heavy drinking also predicted greater use of reward strategies, which were positively associated with satisfaction. However, the magnitude of the indirect effects via punishment was more than twice as large as the mediated effect via reward. Results underscore the importance of an interdependent, dyadic perspective in understanding associations between heavy drinking and marital outcomes as well as differences between punishing and rewarding regulation strategies in these associations.

    Aims Managing patients with alcohol dependence includes assessment for heavy drinking, typically by asking patients. Some recommend biomarkers to detect heavy drinking but evidence of accuracy is limited. Methods Among people with dependence, we assessed the performance of disialo-carbohydrate-deficient transferrin (%dCDT, ≥1.7%), gamma-glutamyltransferase (GGT, ≥66 U/l), either %dCDT or GGT positive, and breath alcohol (> 0) for identifying 3 self-reported heavy drinking levels: any heavy drinking (≥4 drinks/day or >7 drinks/week for women, ≥5 drinks/day or >14 drinks/week for men), recurrent (≥5 drinks/day on ≥5 days) and persistent heavy drinking (≥5 drinks/day on ≥7 consecutive days). Subjects (n = 402) with dependence and current heavy drinking were referred to primary care and assessed 6 months later with biomarkers and validated self-reported calendar method assessment of past 30-day alcohol use. Results The self-reported prevalence of any, recurrent and persistent heavy drinking was 54, 34 and 17%. Sensitivity of %dCDT for detecting any, recurrent and persistent self-reported heavy drinking was 41, 53 and 66%. Specificity was 96, 90 and 84%, respectively. %dCDT had higher sensitivity than GGT and breath test for each alcohol use level but was not adequately sensitive to detect heavy drinking (missing 34–59% of the cases). Either %dCDT or GGT positive improved sensitivity but not to satisfactory levels, and specificity decreased. Neither a breath test nor GGT was sufficiently sensitive (both tests missed 70–80% of cases). Conclusions Although biomarkers may provide some useful information, their sensitivity is low the incremental value over self-report in clinical settings is questionable. PMID:24740846

    This paper examines the real life contexts in which decisions surrounding heavy drinking are made by young adults (that is, on occasions when five or more alcoholic drinks are consumed within a few hours). It presents a conceptual model that views such decision making as a multi-faceted and multi-staged process. The mixed method study draws on purposive data gathered through direct observation of eight social networks consisting of 81 young adults aged between 18 and 25 years in Perth, Western Australia, including in-depth interviews with 31 participants. Qualitative and some basic quantitative data were gathered using participant observation and in-depth interviews undertaken over an eighteen month period. Participants explained their decision to engage in heavy drinking as based on a variety of factors. These elements relate to socio-cultural norms and expectancies that are best explained by the theory of planned behaviour. A framework is proposed that characterises heavy drinking as taking place in a multi-staged manner, with young adults having: 1. A generalised orientation to the value of heavy drinking shaped by wider influences and norms; 2. A short-term orientation shaped by situational factors that determines drinking intentions for specific events; and 3. An evaluative orientation shaped by moderating factors. The value of qualitative studies of decision making in real life contexts is advanced to complement the mostly quantitative research that dominates research on alcohol decision making. PMID:21632161

    Aims: Acute alcohol intoxication itself may act as a trigger for suicidal thoughts and attempts among individuals at risk and may influence the potential lethality of the suicide attempt. This study in alcohol-dependent patients compared the correlates of suicide attempts during a heavy drinking episode with those of suicide attempts during relative sobriety. Methods: In two outpatient and two residential alcohol treatment programs in Warsaw, Poland, 113 patients who reported a suicide attempt during their lifetime were interviewed. The analyses focused on the patients’ most serious suicide attempts and on whether these occurred during a heavy drinking episode. Results: Over two-thirds of the patients reported that their most serious suicide attempt occurred during a period of heavy drinking. A multivariable logistic model indicated that the following factors significantly distinguished those patients whose most serious suicide attempt occurred during a heavy drinking episode: male gender, younger current age, greater severity of alcohol dependence and the attempt being unplanned. Conclusion: Among the patients in treatment for alcohol dependence who made a suicide attempt, the most serious attempt was likely to have been unplanned and committed by men when it occurred during a heavy drinking episode.

    College students are at high risk for engaging in heavy episodic drinking and for experiencing sexual assault. Further, drinking to cope with anxiety motives are associated with sexual assault history and drinking, and thus should be examined when targeting both sexual assault and drinking in college populations. The current study examined the effectiveness of decreasing coping with anxiety drinking motives among underage heavy episodic drinking college women (n=264). Results indicate that a web-based combined alcohol use and sexual assault risk reduction intervention was effective at decreasing drinking to cope with anxiety motives among those with stronger drinking to cope with anxiety motives at baseline. However, the alcohol-only and sexual assault-only interventions were not. Decreases in drinking motives were associated with decreases in heavy episodic drinking. This suggests that alcohol interventions in college populations may not be effectively targeting drinking motives and this preliminary study provides evidence indicating that targeting alcohol and sexual assault together may decrease drinking to cope motives among a high risk population.

    This study sought to examine predictors of parenting trajectories in a sample of heavy drinking and abstaining/light drinking parents. Mixture modeling was used to estimate trajectories of parental discipline styles over time. Two dimensions of parenting were examined: laxness and overreactivity. Changes in these dimensions were examined for each parent. Trajectories for mothers and fathers were very similar and were generally stable from 18 months to 5-6 years child age. Fathers' binge drinking was associated with high levels of both paternal and maternal overreactivity. Mothers with depressed affect had the highest levels of overreactivity, whereas fathers reporting depressed affect were more likely to have moderate levels of laxness. Mothers with high levels of marital satisfaction were more likely to have partners in the stable low overreactivity group. Findings begin to elucidate the nature of early family processes that may contribute to maladaptive child outcomes in heavy drinking families. PMID:18818023

    The ratio of triglycerides to HDL cholesterol (TG/HDL-C ratio) and lipid accumulation product (LAP: a continuous marker of lipid over-accumulation determined by waist circumference and triglycerides) have been proposed to be good predictors of cardiovascular disease. The aim of this study was to clarify the relationships between heavy alcohol drinking and lipid-related indices including TG/HDL-C ratio, LAP, and ratio of LDL cholesterol to HDL cholesterol (LDL-C/HDL-C ratio). The subjects were middle-aged male nondrinkers and heavy drinkers (ethanol intake: ≥66 g per drinking day, which is 2-3 times or more than the generally recommended border level of daily alcohol consumption of 20-30 g). The levels of each lipid-related index after adjustment for age, smoking, and regular exercise were compared among nondrinkers, occasional heavy drinkers, and regular heavy drinkers. Log-transformed TG/HDL-C ratio was significantly higher in occasional heavy drinkers (mean ± standard error: 0.445 ± 0.014) than in nondrinkers (0.388 ± 0.004) and regular heavy drinkers (0.359 ± 0.013), and was not significantly different in nondrinkers and regular heavy drinkers. Log-transformed LAP was significantly higher in occasional heavy drinkers (1.51 ± 0.02) and regular heavy drinkers (1.44 ± 0.02) than in nondrinkers (1.34 ± 0.01), and was significantly higher in occasional heavy drinkers than in regular heavy drinkers. LDL-C/HDL-C ratio was significantly lower in occasional heavy drinkers (2.41 ± 0.04) and regular heavy drinkers (1.72 ± 0.04) than in nondrinkers (2.62 ± 0.01) and was significantly lower in regular heavy drinkers than in occasional heavy drinkers. Results of logistic regression analysis, using odds ratios for high lipid indices of occasional or regular heavy drinkers vs. nondrinkers, agreed with the above results of analysis of covariance. Occasional heavy drinkers showed more detrimental and less favorable levels of the lipid indices than did regular heavy

    To determine whether alcohol outlet density was correlated with heavy and frequent drinking and drinking-related problems, we compared ecological measures of outlet density with survey measures of drinking using a geographic information system and the Harvard School of Public Health College Alcohol Study (n=3,421, site n=8). We identified 966 outlets within 8 2-mile study areas. Densities/site ranged from 32 to 185. Density was correlated with heavy drinking (r=0.82, p=0.01), frequent drinking (r=0.73, p=0.04) and drinking-related problems (r=0.79, p=0.02). Women, underage students and students who picked up binge drinking in college were affected. Implications for prevention and research are discussed.

    Background. State-level ‘age 21’ drinking laws conform generally with the United States National Minimum Drinking Age Act of 1984 (US), and are thought to protect young people from adverse drinking experiences such as heavy episodic drinking (HED, sometimes called ‘binge drinking’). We shed light on this hypothesis while estimating the age-specific risk of transitioning from 1st full drink to 1st HED among 12-to-23-year-old newly incident drinkers, with challenge to a “gender gap” hypothesis and male excess described in HED prevalence reports. Methods. The study population consisted of non-institutionalized civilians in the United States, with nine independently drawn nationally representative samples of more than 40,000 12-to-23-year-olds (2006–2014). Standardized audio computer-assisted self-interviews identified 43,000 newly incident drinkers (all with 1st HED evaluated within 12 months of drinking onset). Estimated age-specific HED risk soon after first full drink is evaluated for males and females. Results. Among 12-to-23-year-old newly incident drinkers, an estimated 20–30% of females and 35–45% of males experienced their 1st HED within 12 months after drinking onset. Before mid-adolescence, there is no male excess in such HED risk. Those who postponed drinking to age 21 are not spared (27% for ‘postponer’ females; 95% CI [24–30]; 42% for ‘postponer’ males; 95% CI [38–45]). An estimated 10–18% females and 10–28% males experienced their 1st HED in the same month of their 1st drink; peak HED risk estimates are 18% for ‘postponer’ females (95% CI [15–21]) and 28% for ‘postponer’ males (95% CI [24–31]). Conclusions. In the US, one in three young new drinkers transition into HED within 12 months after first drink. Those who postpone the 1st full drink until age 21 are not protected. Furthermore, ‘postponers’ have substantial risk for very rapid transition to HED. A male excess in this transition to HED is not

    Background Recent trial results show that an interactive short message service (SMS) text message intervention, Texting to Reduce Alcohol Consumption (TRAC), is effective in reducing heavy drinking in non-treatment-seeking young adults, but may not be optimized. Objective To assess the usability of the TRAC intervention among young adults in an effort to optimize future intervention design. Methods We conducted five focus groups with 18 young adults, aged 18-25 years, who had a history of heavy drinking and had been randomized to 12 weeks of the TRAC intervention as part of a clinical trial. A trained moderator followed a semistructured interview guide. Focus groups were audiotaped, transcribed, and analyzed to identify themes. Results We identified four themes regarding user experiences with the TRAC intervention: (1) ease of use, (2) comfort and confidentiality, (3) increased awareness of drinking behavior, and (4) accountability for drinking behavior. Participants’ comments supported the existing features of the TRAC intervention, as well as the addition of other features to increase personalization and continuing engagement with the intervention. Conclusions Young adults perceived the TRAC intervention as a useful way to help them reduce heavy drinking on weekends. Components that promote ease of use, ensure confidentiality, increase awareness of alcohol consumption, and increase accountability were seen as important. PMID:27335099

    Poor response inhibition has been associated with a wide range of problem behaviours, including addictive behaviours, and could represent a general vulnerability factor. Standard tests of response inhibition have used neutral stimuli. Here we tested whether a deficit in response inhibition in heavy drinkers would be stronger for stimuli related to their problem (alcohol) or not. Response inhibition was assessed with a stop signal task, using four classes of pictures: alcohol-related, soft drinks, erotic (control appetitive categories) and neutral pictures. Participants were 32 heavy and 32 light drinkers. An equal amount of men and women were tested in both drinking groups, in view of recent studies reporting that response disinhibition may be most pronounced in heavy drinking women. Main results were first that no domain-specific differences in response inhibition were found in both groups. Second, heavy drinking females showed stronger response inhibition deficits than other groups. Results are discussed in light of a possible gender difference in response inhibition as a risk factor for addictive behaviours. PMID:19409923

    Objective To assess the impact of a parenting intervention, Familias: Preparando la Nueva Generación (FPNG), intended to support children, on parents heavy drinking. We hypothesized that parent participants of FPNG would reduce their heavy drinking at 1-year follow-up. Methods Parents (N = 281) of middle school children from a large, low-income metropolitan area in the Southwest United States participated in a randomized control trial over 2 years. Results A logistic regression analysis using the maximum likelihood test determined that at Wave 3, parents receiving FPNG reduced heavy drinking behaviors compared to parents in the youth-only condition (odds ratio = .86, p < .05). Conclusions Participating in the parenting program can effectively curb heavy drinking behaviors in parents—an important mechanism through which one may expect changes in youth risk behavior. The practice, policy, and research implications of these unintended findings are promising to the overall effectiveness of a parenting intervention for Mexican-heritage families. PMID:25755619

    Objective This research was designed to evaluate the relative contribution of social norms, demographics, drinking motives, and alcohol expectancies in predicting alcohol consumption and related problems among heavy-drinking college students. Method Participants included 818 (57.6% women) first-year undergraduates who reported at least one heavy-drinking episode in the previous month. In addition to providing demographic information (gender and fraternity/sorority membership) participants completed Web-based assessments of social norms (perceived descriptive norms regarding typical student drinking, injunctive norms regarding friends’ and parents’ approval), motives (social, enhancement, coping, and conformity), and expectancies and evaluations of positive and negative alcohol effects. Results Regression results indicated that descriptive and injunctive norms were among the best predictors of college student drinking. With respect to alcohol problems, results indicated that coping motives accounted for the largest proportion of unique variance. Finally, results revealed that alcohol consumption mediated the relationships between predictors and problems for social norms, whereas coping motives, negative expectancies, and evaluation of negative effects were directly associated with alcohol problems despite having relatively weak or null unique associations with consumption. Conclusions The results of this study substantiate social norms as being among the best predictors of alcohol consumption in this population and suggest that drinking to cope is a better predictor of problems. The findings are discussed in terms of practical prevention and treatment implications. PMID:17568961

    Objective To examine use of and interest in cessation strategies among nondaily and daily college student smokers. Participants 800 undergraduate student smokers aged 18 to 25. Methods The authors examined nondaily versus daily smoking in relation to use of and interest in cessation strategies using an online survey. Results Nondaily (65.8%) versus daily smokers (34.3%) were more likely to have made a quit attempt (p = .01) but less likely to have used any assistance (p < .001). Nondaily smokers were less interested in pharmacotherapy and traditional behavioral interventions; however, there was no difference in interest in technology-based interventions among nondaily versus daily smokers. Controlling for covariates, there were no significant differences in interest in traditional or technology-based behavioral interventions. Higher motivation, lower confidence, and depressive symptomatology were related to interest in each intervention. Smoking for social reasons was related to interest in technology-based interventions. Conclusions Different intervention strategies may be appropriate for nondaily and daily smokers. PMID:22420696

    Heavy drinking among young people is linked to negative consequences including other risky behaviours, educational failure and premature mortality. There is a lack of research examining factors that influence heavy and binge drinking in early adolescence as prior work has focused on older teenagers. The objective of this paper was to identify individual and family factors associated with drunkenness and episodes of heavy drinking in early adolescence. We analysed data on 11,046 11year olds from the UK Millennium Cohort Study. Multivariate logistic regression was used to estimate odds ratios for associations. 1.2% of participants reported having been drunk, and 0.6% reported having had 5 or more drinks in a single episode. Participants who reported drunkenness were more likely to be boys (1.6% vs 0.7%, p<0.01), to have socioemotional difficulties (2.6% vs 1.0%, p<0.001), to report antisocial behaviours (none=0.6%, 1=2.0%, 2 or more=7.0%, p<0.001), report truancy (6.0% vs 1.0%, p<0.001), smoke cigarettes (12.0% vs 0.8%, p<0.001). Parental drinking did not appear to be associated with the odds of drunkenness. Associated with higher odds of drunkenness were: having friends who drank (OR=5.17); having positive expectancies towards alcohol (OR 2+=2.02); ever having smoked cigarettes (OR=5.32); the mother-child relationship not being close (OR=2.17). Associated with a reduced odds of drunkenness was having a heightened perception of harm from drinking 1-2 drinks daily (OR - some risk=0.48, great risk=0.40). Our findings support policies aimed at multiple levels, starting in the preadolescent years, which incorporate individual, family, and peer factors. PMID:27413004

    Heavy alcohol consumption has been associated with collegiate sporting events, but little is known about specific levels of consumption over the course of an entire sports season. Ongoing web-based daily monitoring at the University of Texas at Austin allowed assessment of drinking levels of students (n=541) over two full football seasons. High-profile football game days were among the heaviest days for alcohol consumption, comparable to consumption on other well-known drinking days such as New Years Eve and Halloween weekend. Men increased their drinking for all games, and women with greater social involvement were more likely to drink heavily during away games. Among lighter drinkers, away games were associated with a greater likelihood of behavioral risks as intoxication increased. PMID:17662537

    The authors examined the ownership of false identification (fake ID) for the purpose of obtaining alcohol and the relation of fake ID ownership to heavy drinking in a longitudinal sample of college students under 21 years of age. A sample of 3,720 undergraduates was assessed the summer prior to college entrance and during the 4 semesters comprising freshman and sophomore years. Regression analyses were used to estimate bidirectional relations between consumption and fake ID ownership. Sex, Greek membership, and prior drinking were controlled. Results showed that fake ID ownership increased over time (12.5% pre-college to 32.2% fourth semester) and that Greek members were more likely than others to own fake IDs. Fake ID ownership predicted concurrent and next-semester heavy drinking with increasing strength over time. Also, the acquisition (onset) of fake ID ownership at each time point was predicted by previous-semester consumption. When traditional, robust risk factors of consumption are controlled, fake ID ownership meaningfully relates to heavy drinking in college. It thus presents a significant public health problem, addressable through training for alcohol servers and retailers, punitive measures toward fake ID owners, and other possible interventions.

    The concentrations of heavy metals such as Cd, Cr, Cu, Mn, Ni, Pb and Zn were investigated in drinking water sources (surface and groundwater) collected from Swat valley, Khyber Pakhtunkhwa, Pakistan. The potential health risks of heavy metals to the local population and their possible source apportionment were also studied. Heavy metal concentrations were analysed using atomic absorption spectrometer and compared with permissible limits set by Pakistan Environmental Protection Agency and World Health Organization. The concentrations of Cd, Cr, Ni and Pb were higher than their respective permissible limits, while Cu, Mn and Zn concentrations were observed within their respective limits. Health risk indicators such as chronic daily intake (CDI) and health risk index (HRI) were calculated for adults and children separately. CDIs and HRIs of heavy metals were found in the order of Cr > Mn > Ni > Zn > Cd > Cu > Pb and Cd > Ni > Mn > Cr > Cu > Pb > Zn, respectively. HRIs of selected heavy metals in the drinking water were less than 1, indicating no health risk to the local people. Multivariate and univariate statistical analyses showed that geologic and anthropogenic activities were the possible sources of water contamination with heavy metals in the study area.

    The DSM-5 has created significant changes in the definition of alcohol use disorders (AUDs). Limited work has considered the impact of these changes in specific populations, such as heavy-drinking college students. Latent class analysis (LCA) is a person-centered approach that divides a population into mutually exclusive and exhaustive latent classes, based on observable indicator variables. The present research was designed to examine whether there were distinct classes of heavy-drinking college students who met DSM-5 criteria for an AUD and whether gender, perceived social norms, use of protective behavioral strategies (PBS), drinking refusal self-efficacy (DRSE), self-perceptions of drinking identity, psychological distress, and membership in a fraternity/sorority would be associated with class membership. Three-hundred and ninety-four college students who met DSM-5 criteria for an AUD were recruited from three different universities. Two distinct classes emerged: Less Severe (86%), the majority of whom endorsed both drinking more than intended and tolerance, as well as met criteria for a mild AUD; and More Severe (14%), the majority of whom endorsed at least half of the DSM-5 AUD criteria and met criteria for a severe AUD. Relative to the Less Severe class, membership in the More Severe class was negatively associated with DRSE and positively associated with self-identification as a drinker. There is a distinct class of heavy-drinking college students with a more severe AUD and for whom intervention content needs to be more focused and tailored. Clinical implications are discussed.

    Alcohol use disorder (AUD) is debilitating and costly. Identification and better understanding of risk factors influencing the development of AUD remain a research priority. Although early life exposure to trauma increases the risk of adulthood psychiatric disorders, including AUD, many individuals exposed to early life trauma do not develop psychopathology. Underlying genetic factors may contribute to differential sensitivity to trauma experienced in childhood. The hypothalamic-pituitary-adrenal (HPA) axis is susceptible to long-lasting changes in function following childhood trauma. Functional genetic variation within FKBP5, a gene encoding a modulator of HPA axis function, is associated with the development of psychiatric symptoms in adulthood, particularly among individuals exposed to trauma early in life. In the current study, we examined interactions between self-reported early life trauma, past-year life stress, past-year trauma, and a single nucleotide polymorphism (rs1360780) in FKBP5 on heavy alcohol consumption in a sample of 1,845 college students from two university settings. Although we found no effect of early life trauma on heavy drinking in rs1360780*T-allele carriers, rs1360780*C homozygotes exposed to early life trauma had a lower probability of heavy drinking compared to rs1360780*C homozygotes not exposed to early life trauma (P < 0.01). The absence of an interaction between either current life stress or past-year trauma, and FKBP5 genotype on heavy drinking suggests that there exists a developmental period of susceptibility to stress that is moderated by FKBP5 genotype. These findings implicate interactive effects of early life trauma and FKBP5 genetic variation on heavy drinking. © 2016 Wiley Periodicals, Inc. PMID:27196697

    Toenail is metabolic end product of the skin, which can provide information about heavy metal accumulation in human cells. Slow growth rates of toenail can represent heavy metal exposure from 2 to 12 months before the clipping. The toenail is a non-invasive biomarker that is easy to collect and store and is stable over time. In this systematic review, the suitability of toenail as a long-term biomarker was reviewed, along with the analysis and validation of toenail and confounders to heavy metal. This systematic review has included 30 articles chosen from a total of 132 articles searched from online electronic databases like Pubmed, Proquest, Science Direct, and SCOPUS. Keywords used in the search included "toenail", "biomarker", "heavy metal", and "drinking water". Heavy metal in toenail can be accurately analyzed using an ICP-MS instrument. The validation of toenail heavy metal concentration data is very crucial; however, the Certified Reference Material (CRM) for toenail is still unavailable. Usually, CRM for hair is used in toenail studies. Confounders that have major effects on heavy metal accumulation in toenail are dietary intake of food and supplement, smoking habit, and overall health condition. This review has identified the advantages and limitations of using toenail as a biomarker for long-term exposure, which can help future researchers design a study on heavy metal exposure using toenail.

    The levels of heavy metals in Shanghai drinking water conservation area were determined, and the spatial distributions and main sources of heavy metals were investigated. Moreover, the ecological risk assessment of heavy metals was conducted. Some conclusions can be drawn as follows: (1) The average concentrations of Cd, Hg, Pb, Cu, Zn, Ni, Cr and As in road dust were 0.80, 0.23, 148.45, 127.52, 380.57, 63.17, 250.38 and 10.37 mg x kg(-1) respectively. In terms of the pollution level, the values of soils were relatively lower, with the mean contents of 0.16 (Cd), 0.33 (Hg), 30.14 (Pb), 30.66 (Cu), 103.79 (Zn), 24.04 (Ni), 65.75 (Cr) and 6.31 mg x kg(-1) (As) severally; meanwhile the average levels of heavy metals in vegetables were 0.010 (Cd), 0.016 (Hg), 0.36 (Pb), 12.80 (Cu), 61.69 (Zn), 2.04 (Ni), 2.41 (Cr) and 0.039 mg x kg(-1) (As) respectively. (2) Semivariogram and multivariate analysis indicated that heavy metals pollution of soils was induced by anthropogenic activities mostly, and the pollutants produced by traffic were the major source of heavy metals in road dust. (3) The order for heavy metal enrichment coefficients of vegetables was as following: Zn (0.589) > Cu (0.412) > 0.102 (Ni) > Cd (0.059) > Cr (0.061) > Hg (0.056) > Pb (0.012) > As (0.007), and the results indicated that Cd and Zn in vegetables were mainly from the soils, and the other metals were probably from the pollutants in the atmosphere. (4) Sediments in drinking water conservation area were probably derived from soils around; however, there was no significant relationship between heavy metals contents of them. (5) The results of ecological risk assessment of heavy metals showed that heavy metals in soils were in no-warning to warning situation, and warning to light-warning situation for road dust and vegetables. The fuzzy synthesis judgment for all the environmental media around drinking water conservation area was warning to light-warning.

    The purpose of this mixed methods study was to describe the sleep and psychological characteristics of heavy-drinking college students, their perceptions of sleep and sleep/alcohol interactions, and their reactions to a proposed integrated sleep and alcohol Web-based intervention. Students (N = 24) completed standardized surveys and participated in semistructured focus group interviews. Participants reported a high degree of sleep disturbance, sleep obstacles, and sleep-related consequences, which were validated by both quantitative and qualitative investigations. Sleep disturbance and sleep-related impairment were associated with more frequent drinking and greater risks from drinking. Participants perceived that alcohol has positive and negative effects on sleep latency, continuity, and quality. They expressed overall enthusiasm for the intervention but had specific content and format preferences.

    The aim of the present study was to examine the mediational effect of masculine gender role stress on the relation between adherence to dimensions of a hegemonic masculinity and male-to-female intimate partner physical aggression. Men’s history of heavy episodic drinking was also examined as a moderator of the proposed mediation effect. A sample of 392 heterosexual men from the southeastern United States who had been in an intimate relationship within the past year completed measures of hegemonic masculine norms (i.e., status, toughness, and antifemininity), masculine gender role stress, alcohol use patterns, and intimate partner physical aggression. Results indicated that the indirect effects of adherence to the antifemininity and toughness norms on physical aggression toward female intimate partners via masculine gender role stress were significant and marginal, respectively. A significant indirect effect of status was not detected. Moreover, subsequent analyses revealed that the indirect effects of antifemininity and toughness were significant only among men with a history of heavy episodic drinking. These findings suggest that heavy episodic drinking exacerbates a gender-relevant stress pathway for intimate partner aggression among men who adhere to specific norms of masculinity. Overall, results suggest that the proximal effect of heavy episodic drinking focuses men’s attention on gender-based schemas associated with antifemininity and toughness, which facilitates partner-directed aggression as a means to demonstrate these aspects of their masculinity. Implications for the intersection between men’s adherence to specific norms of hegemonic masculinity, cognitive appraisal of gender relevant situations, and characteristic patterns of alcohol consumption are discussed.

    Providing high-quality, uncontaminated drinking water is an essential component of rodent husbandry. Acidification of drinking water is a common technique to control microbial growth but is not a benign treatment. In addition to its potential biologic effects, acidified water might interact with the water-delivery system, leading to the leaching of heavy metals into the drinking water. The goal of the current study was to evaluate the effects of water acidification and autoclaving on water-bottle assemblies. The individual components of the system (stainless-steel sipper tubes, rubber stoppers, neoprene stoppers, and polysulfone water bottles) were acid-digested and analyzed for cadmium, chromium, copper, iron, lead, magnesium, manganese, selenium, and zinc to quantify the metal composition of each material. In addition the amounts of these metals that leached into tap and acidified water with and without autoclaving were quantified after 1 wk of contact time. On a weight basis, sipper tubes contained the largest quantities of all metals except magnesium and zinc, which were greatest in the neoprene stoppers. Except for cadmium and selenium, all metals had leached into the water after 1 wk, especially under the acidified condition. The quantities of copper, lead, and zinc that leached into the drinking water were the most noteworthy, because the resulting concentrations had the potential to confound animal experiments. On the basis of these findings, we suggest that water-quality monitoring programs include heavy metal analysis at the level of water delivery to animals. PMID:23562029

    This study was undertaken to assess the heavy metal concentration of the drinking water with respect to zinc, copper, cadmium, manganese, lead and arsenic in Kamrup district of Assam, India. Ground water samples were collected from tube wells, deep tube wells and ring wells covering all the major hydrogeological environs. Heavy metals in groundwater are estimated by using Atomic Absorption Spectrometer, Perkin Elmer Analyst 200. Data were assessed statistically to find the distribution pattern and other related information for each metal. The study revealed that a good number of the drinking water sources were contaminated with cadmium, manganese and lead. Arsenic concentrations although did not exceeded WHO limits but was found to be slightly elevated. Copper and zinc concentrations were found to be within the prescribed WHO limits. An attempt has also been made to ascertain the possible source of origin of the metals. Positive and significant correlation existing between manganese with zinc and copper indicates towards their similar source of origin and mobility. In view of the present study and the level of heavy metal contamination, it could be suggested to test the potability of the water sources before using it for drinking purpose.

    Concentrations distribution of the Cu, Hg, Cd, As in drinking water in the 8 city districts and 10 counties in Beijing was studied based on a total of 120 random samples. Health risks associated with 4 metals in drinking water were assessed using USEPA health risk assessment model. The results showed that the concentrations of the heavy metals in drinking water in Beijing ranged from 0.81 to 6.96 micrograms.L-1 for Cu, 0.34-0.82 microgram.L-1 for Cd, 0.10-0.74 microgram.L-1 for Hg and 0.19-3.02 micrograms.L-1 for As. Among the health risks caused by the carcinogens in drinking water, the largest risk associated with As should be in Tongzhou County (2.0 x 10(-5).a-1) and that with Cd should be in Changping County (2.3 x 10(-6).a-1), while both were significantly lower than the maximum allowance levels recommended by ICRP(5 x 10(-5).a-1). Among the non-carcinogenic risks in drinking water, the largest risk was the risk associated with Hg, followed by Cu. The non-carcinogenic risks levels ranged from 10(-8) to 10(-9), much lower than the maximum allowance levels recommended by ICRP. PMID:15202233

    Heavy drinking smokers constitute a distinct sub-population of smokers for whom traditional smoking cessation therapies may not be effective. Recent evidence suggested that combined varenicline (VAR) and naltrexone (NTX) therapy may be more efficacious than either monotherapy alone in reducing smoking and drinking-related behavior in this population. The manner in which individuals smoke a cigarette (i.e., smoking topography) may be predictive of smoking cessation outcomes, yet the effects of smoking pharmacotherapies on puffing behavior have not been thoroughly examined. Therefore, the current double-blind medication study examined the effects of VAR alone (1mg BID), low dose NTX alone (25mg QD), the combination of VAR+NTX, and placebo on smoking topography measures in heavy drinking, non-treatment seeking daily smokers (n=120). After a 9-day titration period, participants completed a laboratory session in which they smoked their first cigarette of the day using a smoking topography device following 12-hrs of nicotine abstinence and consumption of an alcoholic beverage (BrAC = 0.06 g/dl). The primary measures were puff count, volume, duration, and velocity and inter-puff interval (IPI). Independent of medication group, puff velocity and IPI increased, while puff volume and duration decreased, over the course of the cigarette. The active medication groups, vs. the placebo group, had significantly blunted puff duration and velocity slopes over the course of the cigarette, and this effect was particularly evident in the VAR+NTX group. Additionally, the VAR+NTX group demonstrated lower average IPI than the monotherapy groups and lower average puff volume than all other groups. These results suggest that smoking pharmacotherapies, particularly the combination of VAR+NTX, alter smoking topography in heavy drinking smokers, producing a pattern of less intense puffing behavior. As smoking topography has been predictive of the ability to quit smoking, future studies should

    Along with post-traumatic stress disorder (PTSD), mild traumatic brain injury (mTBI) is considered one of the “signature wounds” of combat operations in Iraq (Operation Iraqi Freedom [OIF]) and Afghanistan (Operation Enduring Freedom [OEF]), but the role of mTBI in the clinical profiles of Veterans with other comorbid forms of postdeployment psychopathology is poorly understood. The current study explored the deployment risk and postdeployment health profiles of heavy drinking OIF and OEF Veterans as a function of mTBI. Sixty-nine heavy-drinking OIF/OEF Veterans were recruited through a Veterans’ Affairs Medical Center and completed questionnaires and structured interviews assessing war-zone experiences, postdeployment drinking patterns, and PTSD symptoms. Veterans with positive mTBI screens and confirmed mTBI diagnoses endorsed higher rates of combat experiences, including direct and indirect killing, and met criteria for PTSD at a higher rate than Veterans without a history of mTBI. Both PTSD and combat experiences independently predicted screening positive for mTBI, whereas only combat experiences predicted receiving a confirmed mTBI diagnosis. mTBI was not associated with any dimension of alcohol use. These results support a growing body of literature linking mTBI with PTSD. PMID:22808885

  3. Negative affect is associated with alcohol, but not cigarette use in heavy drinking smokers.

    Co-use of alcohol and cigarettes is highly prevalent, and heavy drinking smokers represent a large and difficult-to-treat subgroup of smokers. Negative affect, including anxiety and depressive symptomatology, has been associated with both cigarette and alcohol use independently, but less is known about the role of negative affect in heavy drinking smokers. Furthermore, while some studies have shown negative affect to precede substance use, a precise biobehavioral mechanism has not been established. The aims of the present study were twofold. First, to test whether negative affect is associated with alcohol and cigarette use in a large community sample of heavy drinking smokers (n=461). And second, to examine craving as a plausible statistical mediator of the association between negative affect and alcohol and/or cigarette use. Hypothesis testing was conducted using a structural equation modeling approach with cross-sectional data. Analysis revealed a significant main effect of negative affect on alcohol use (β=0.210, p<0.05), but not cigarette use (β=0.131, p>0.10) in this sample. Mediational analysis revealed that alcohol craving was a full statistical mediator of this association (p<0.05), such that there was no direct association between negative affect and alcohol use after accounting for alcohol craving. These results are consistent with a negative reinforcement and relief craving models of alcohol use insofar as the experience of negative affect was associated with increased alcohol use, and the relationship was statistically mediated by alcohol craving, presumably to alleviate negative affect. Further longitudinal or experimental studies are warranted to enhance the causal inferences of this mediated effect. PMID:25117849

    Heavy drinking smokers represent a sizeable subgroup of smokers for whom nicotine deprivation and alcohol use increases the urge to smoke in the laboratory and predicts lapses during smoking cessation. The manner in which individuals smoke a cigarette (i.e. smoking topography) provides a reliable index of smoking intensity and reinforcement, yet the effects of affect on smoking topography have not been thoroughly examined in heavy drinking smokers. The current study examined how affect and nicotine deprivation predict smoking behavior as participants (N=27) smoked one cigarette using a smoking topography device after 12-h of nicotine abstinence and after a priming dose of alcohol (target BrAC=0.06g/dl). Primary smoking topography measures were puff volume, velocity, duration, and inter-puff interval (IPI). The effect of nicotine deprivation was measured by the Minnesota Nicotine Withdrawal Scale (MNWS) and the Profile of Mood States (POMS). Measures were obtained at baseline (i.e. 12-h of nicotine abstinence and pre-alcohol) and 30-minutes after alcohol administration (i.e. peak BrAC). Results revealed post-priming negative affect significantly moderated the trajectories of puff volume, puff duration and IPI (p's<0.05) over the course of the cigarette, such that those with greater negative affect had flatter slopes for volume and duration and increasingly infrequent puffs. Our results suggest that baseline and post-priming negative affect following nicotine deprivation alters smoking patterns and increases nicotine exposure throughout a single cigarette. Future studies need to examine differential amounts of nicotine deprivation on response to alcohol and smoking in heavy drinking smokers. PMID:27240211

    Co-use of alcohol and cigarettes is highly prevalent, and heavy drinking smokers represent a large and difficult-to-treat subgroup of smokers. Negative affect, including anxiety and depressive symptomatology, has been associated with both cigarette and alcohol use independently, but less is known about the role of negative affect in heavy drinking smokers. Furthermore, while some studies have shown negative affect to precede substance use, a precise biobehavioral mechanism has not been established. The aims of the present study were twofold. First, to test whether negative affect is associated with alcohol and cigarette use in a large community sample of heavy drinking smokers (n=461). And second, to examine craving as a plausible statistical mediator of the association between negative affect and alcohol and/or cigarette use. Hypothesis testing was conducted using a structural equation modeling approach with cross-sectional data. Analysis revealed a significant main effect of negative affect on alcohol use (β=0.210, p<0.05), but not cigarette use (β=0.131, p>0.10) in this sample. Mediational analysis revealed that alcohol craving was a full statistical mediator of this association (p<0.05), such that there was no direct association between negative affect and alcohol use after accounting for alcohol craving. These results are consistent with a negative reinforcement and relief craving models of alcohol use insofar as the experience of negative affect was associated with increased alcohol use, and the relationship was statistically mediated by alcohol craving, presumably to alleviate negative affect. Further longitudinal or experimental studies are warranted to enhance the causal inferences of this mediated effect.

    Heavy drinking smokers represent a sizeable subgroup of smokers for whom nicotine deprivation and alcohol use increases the urge to smoke in the laboratory and predicts lapses during smoking cessation. The manner in which individuals smoke a cigarette (i.e. smoking topography) provides a reliable index of smoking intensity and reinforcement, yet the effects of affect on smoking topography have not been thoroughly examined in heavy drinking smokers. The current study examined how affect and nicotine deprivation predict smoking behavior as participants (N=27) smoked one cigarette using a smoking topography device after 12-h of nicotine abstinence and after a priming dose of alcohol (target BrAC=0.06g/dl). Primary smoking topography measures were puff volume, velocity, duration, and inter-puff interval (IPI). The effect of nicotine deprivation was measured by the Minnesota Nicotine Withdrawal Scale (MNWS) and the Profile of Mood States (POMS). Measures were obtained at baseline (i.e. 12-h of nicotine abstinence and pre-alcohol) and 30-minutes after alcohol administration (i.e. peak BrAC). Results revealed post-priming negative affect significantly moderated the trajectories of puff volume, puff duration and IPI (p's<0.05) over the course of the cigarette, such that those with greater negative affect had flatter slopes for volume and duration and increasingly infrequent puffs. Our results suggest that baseline and post-priming negative affect following nicotine deprivation alters smoking patterns and increases nicotine exposure throughout a single cigarette. Future studies need to examine differential amounts of nicotine deprivation on response to alcohol and smoking in heavy drinking smokers.

    Importance of peer counselor posttraining supervision on motivational interviewing (MI) microskills and postintervention drinking outcomes were evaluated in a sample of heavy-drinking undergraduate students completing Brief Alcohol Screening and Intervention for College Students (BASICS; L.A. Dimeff, J.S. Baer, D.R. Kivlahan, & G.A. Marlatt, 1999). Two peer counselor groups were trained using identical protocols. Posttraining, one group was randomized to receive supervision, whereas the other received no supervision. Groups were subsequently compared on MI microskills. College students (n = 122) were randomly assigned to either assessment-only control, supervision, or no supervision groups and completed a BASICS intervention. Postintervention drinking outcomes were examined. Results suggested supervision aided peer counselors in reducing use of closed-ended questions. Both treatment groups reduced total drinks per week and heavy-drinking behaviors compared to control. No differences on peak blood alcohol concentration (BAC) or alcohol-related consequences were observed. Differences in supervision did not influence drinking outcomes; however, posttraining supervision for peer counselors deficient in MI microskills may be needed to improve BASICS fidelity.

    Objectives. We examined loose cigarette (loosie) purchasing behavior among young adult (aged 18–26 years) smokers at bars in New York City and factors associated with purchase and use. Methods. Between June and December 2013, we conducted cross-sectional surveys (n = 1916) in randomly selected bars and nightclubs. Using multivariable logistic regression models, we examined associations of loose cigarette purchasing and use with smoking frequency, price, social norms, cessation behaviors, and demographics. Results. Forty-five percent (n = 621) of nondaily smokers and 57% (n = 133) of daily smokers had ever purchased a loosie; 15% of nondaily smokers and 4% of daily smokers reported that their last cigarette was a loosie. Nondaily smokers who never smoked daily were more likely than were daily smokers to have last smoked a loosie (odds ratio = 7.27; 95% confidence interval = 2.35, 22.48). Quitting behaviors and perceived approval of smoking were associated with ever purchasing and recently smoking loosies. Conclusions. Loosie purchase and use is common among young adults, especially nondaily smokers. Smoking patterns and attitudes should be considered to reduce loose cigarette purchasing among young adults in New York City. PMID:25880951

    A large subset of individuals who smoke cigarettes do not smoke regularly, but the assessments used to collect data on cigarette consumption in nondaily smokers have not been rigorously evaluated. The current study examined several self-report and biomarker approaches to the assessment of cigarette use in a sample of nondaily smokers (n = 176). Participants were randomly assigned to a daily monitoring condition (n = 89), requiring a daily report of the number of cigarettes smoked in the previous 24 hours, or a no monitoring condition (n = 87). Number of cigarettes smoked over the first 28 days of the study was assessed using 2 quantity frequency measures, a graduated frequency measure, and a timeline follow back (TLFB) interview at the Session 5 study visit. Hair nicotine (NIC), hair cotinine (COT), and expired-air carbon monoxide (CO) were collected from each participant. Total cigarettes reported via daily report were strongly correlated with all Session 5 measures of total cigarettes, but were most strongly associated with TLFB total cigarettes. Collapsed CO across 5 sessions was the biomarker most strongly correlated with daily report total cigarettes. The results support the use of daily report and TLFB methods of assessing cigarette use in nondaily smokers. Results also support the use of CO as appropriate biological markers of exposure in nondaily smokers, and point to some limitations in the use of hair biomarkers in this population.

    Malaysia has abundant sources of drinking water from river and groundwater. However, rapid developments have deteriorated quality of drinking water sources in Malaysia. Heavy metal studies in terms of drinking water, applications of health risk assessment and bio-monitoring in Malaysia were reviewed from 2003 to 2013. Studies on heavy metal in drinking water showed the levels are under the permissible limits as suggested by World Health Organization and Malaysian Ministry of Health. Future studies on the applications of health risk assessment are crucial in order to understand the risk of heavy metal exposure through drinking water to Malaysian population. Among the biomarkers that have been reviewed, toenail is the most useful tool to evaluate body burden of heavy metal. Toenails are easy to collect, store, transport and analysed. This review will give a clear guidance for future studies of Malaysian drinking water. In this way, it will help risk managers to minimize the exposure at optimum level as well as the government to formulate policies in safe guarding the population.

    This study used latent growth mixture modeling to identify discrete developmental patterns of heavy drinking, perceived parental disapproval of substance use, and association with peers who drink from early to late adolescence among a sample of 5,591 youth. We also examined associations among these trajectories to determine how the development of heavy drinking relates to the development of perceived parental disapproval of substance use and association with peer drinkers, both separately and jointly. We found that youth who perceived that their parents maintained consistently strong disapproval of substance use throughout adolescence were much more likely to abstain from heavy drinking during this period than were youth who reported that their parents’ disapproval for substance use either decreased or was maintained at only a moderate level. Furthermore, we found that across a variety of peer contexts—stable high association with drinking peers, stable low association, and increasing association—youth were at lowest risk for developing problematic patterns of heavy drinking when they perceived that their parents maintained strong disapproval of substance use throughout adolescence.

    Background and Aims Excessive alcohol use is assumed to affect maturation of cognitive functioning in adolescence. However, most existing studies that have tested this hypothesis are seriously flawed due to the use of selective groups and/or cross-sectional designs, which limits the ability to draw firm conclusions. This longitudinal study investigated whether patterns of alcohol use predicted differences in maturation of executive functioning in adolescence. Additionally, gender was tested as a possible moderator. Methods We used data from the Tracking Adolescents’ Individual Lives Survey (TRAILS), which comprises a cohort of 2,230 Dutch adolescents. Maturation of executive functioning was measured by assessing the standardized improvement on each of four basic executive functions (i.e., inhibition, working memory, and shift- and sustained attention) between ages 11 and 19. Participants were assigned to one of six (heavy) drinking groups (i.e., non-drinkers, light drinkers, infrequent heavy drinkers, increased heavy drinkers, decreased heavy drinkers, and chronic heavy drinkers). We conducted linear regression analyses, and adjusted for relevant confounders. Results The six drinking groups did not reveal significant differences in maturation between drinking groups. E.g., maturation executive functioning of chronic heavy drinkers in comparison to non-drinkers; inhibition: B = -0.14, 95% CI [-0.41 to 0.14], working memory: B = -0.03, 95% CI [-0.26 to 0.21], shift attention: B = 0.13, 95% CI [-0.17 to 0.41], sustained attention: B = 0.12, 95% CI [-0.60 to 0.36]. Furthermore, gender was not found to be a significant moderator. Conclusions Four years of weekly heavy drinking (i.e., chronic heavy drinkers) did not result in measurable impairments in four basic executive functions. Thus, regular heavy drinking in adolescence does not seem to affect these basic behavioural measures of executive functioning. PMID:26489080

    Nearly all college student smokers also drink alcohol, and smoking and heavy episodic drinking (HED) commonly co-occur. However, few studies have examined the factors that concurrently influence smoking and HED among college students and, to date, no interventions have been developed that target both HED and smoking in this population. The objective of the current study was to develop and evaluate a mobile feedback intervention that targets HED and smoking. Participants (N = 94) were non-treatment-seeking college students (M(age) = 20.5 years, SD = 1.7) who engaged in at least a single HED episode in the past 2 weeks and reported concurrent smoking and drinking at least once a week. Participants were randomized to receive either the mobile intervention for 14 days, complete mobile assessments (without intervention) for 14 days, or complete minimal assessments (without intervention or mobile assessments). At a 1-month follow-up, compared with the minimal assessment condition, we observed significant reductions in the number of cigarettes per smoking day in both the mobile intervention (d = 0.55) and mobile assessment (d = 0.45) conditions. Among those randomized to the mobile intervention, receiving more modules of the intervention was significantly associated with a lower likelihood of any drinking during the 14-day assessment period and significant reductions in smoking at 1-month follow-up. The mobile intervention did not result in significant reductions in HED or concurrent smoking and drinking. Future research should continue to examine ways of using technology and the real-time environment to improve interventions for HED and smoking.

    Heavy drinking and associated negative consequences remain a serious problem among college students. In a secondary analysis of data from two published study, the authors examine the correlation between minimum legal age to purchase and/or consume alcohol and rates of heavy drinking among college students in 22 countries. The published studies use identical definitions of heavy drinking and similar methodologies. In the study of 20 European countries and the United States, there is a positive correlation between prevalence of heavy drinking and both minimum legal purchase age (r =.34) and minimum legal drinking age (r =.19); in the study of Canada and the United States, there is a perfect positive correlation (r = 1.0). Examination of this evidence does not support the conclusion that a lower minimum legal age for purchase and/or consumption of alcoholic beverages is a protective factor for decreasing heavy drinking among college students.

    Drinking water containing heavy metals above the maximum permissible limits cause potential risk to human health. The aim of this study was to determine the groundwater suitability for drinking use based on heavy metal concentration and the associated human exposure risk in an intensively irrigated part of the Cauvery river basin, Tamil Nadu, India. Sixteen heavy metals analysed were in the order of dominance of chromium < zinc < copper < cadmium < cobalt < iron < aluminium < nickel < titanium < zirconium < boron < silver < manganese < lead < lithium < silicon in groundwater. Chromium and zinc were within permissible limits of the Bureau of Indian Standards for drinking water quality, and silver, lead and nickel were above limits in all the groundwater samples. In less than 50 % of the groundwater samples, aluminium, boron, cadmium, copper, iron and manganese exceeded their individual permissible limits. Heavy metal pollution index based on 11 heavy metals indicated that groundwater quality of this area is poor-to-unsuitable. Non-carcinogenic risk for humans due to ingestion of groundwater through drinking water pathway was very high for infants, children and adults. Silver, lead, nickel, cadmium and manganese largely contributed to the health hazard. Sources of heavy metals were identified to be geological and from human activities, i.e., application of fertilizers in agricultural fields, seawater intrusion due to intensive pumping for agriculture and wastewater from industries. Groundwater and surface water in this area pose large threat due to high levels of heavy metals, and it is necessary to avoid this water for drinking due to potential risk of health hazard. This study also demonstrated the application of HPI and human exposure hazard index to study the groundwater quality based on heavy metals' concentration.

    Using retrospective reports obtained during treatment visits in 138 heavy drinkers, we found that topiramate’s reduction of heavy drinking was moderated by a polymorphism (rs2832407) in GRIK1, which encodes the GluK1 kainate subunit (Kranzler et al., 2014a). A subsequent analysis of that 12-week topiramate treatment trial showed similar effects of medication and genotype on daily drinking reports obtained via interactive voice response technology (IVR; Kranzler et al., 2014b). Specifically, rs2832407*C-allele homozygotes treated with topiramate reported lower levels of drinking than those receiving placebo. This group also had the largest decreases in the expected positive effects of drinking (i.e., expectancies) and desire to drink. To extend that analysis, which focused on how mean levels of desire and expectancies changed over time with treatment, we used a within-person approach to examine whether daily variation in expectancies and desire to drink interact with topiramate treatment and genotype to predict nighttime drinking levels. In contrast to the previous analysis (Kranzler et al., 2014b), here we focus on whether alcohol expectancies and desire to drink moderate the effects of topiramate on drinking. Results showed a three-way interaction of daily expectancies with genotype and medication, such that the protective effect of topiramate on nighttime drinking among rs2832407*C-allele homozygotes was decreased on days characterized by relatively high levels of anticipated positive effects of alcohol. There was no moderating effect of desire to drink or negative alcohol expectancies. Thus, there is specific moderation of the effects of topiramate by both genotype and cognitive process.

    Aims To identify childhood and adolescent factors differentiating heavy alcohol users in early adulthood from more moderate users or abstainers. Design Low-income participants followed from birth to age 28 years. Participants A total of 178 adults (95 males) who were first-born children of low-income mothers recruited in Minneapolis, Minnesota, during their third trimester of pregnancy. Measurements Maternal hostility (24/42 months), externalizing and internalizing behavior problems (9 years), peer acceptance and academic achievement (12 years), maternal alcohol use and participants’ drinking behavior (16 years), quantity of alcohol use per occasion (19, 23 and 26 years), alcohol use disorders (28 years). Findings For men: (i) higher amounts of alcohol consumption at age 16 increased the odds of being a heavy drinker compared to an abstainer (age 19) and a moderate drinker (ages 23 and 26); (ii) lower achievement scores at age 12 and having a mother who drank more when the participant was age 16 increased the odds of being a heavy drinker compared to moderate drinker (age 26). Higher levels of externalizing behavior problems at age 9 and drinking more when the participants were age 16 increased the odds that men would have a current alcohol use disorder at age 28. For women: (i) drinking more at age 16 increased the odds of being a heavy drinker compared to being either an abstainer or a moderate drinker (age 26); (ii) having higher levels of achievement at age 12 increased the odds of being a heavy drinker compared to an abstainer at age 23. Adolescent alcohol use mediated the relation between externalizing behavior at age 9 and alcohol use at age 26 for women. Conclusions Problem drinking may be the result of a long-term developmental process wherein childhood externalizing behavior problems sets a pathway leading to heavy drinking during and after adolescence.

    This study examines the sociodemographic factors associated with daily fruit and vegetable (FV) consumption in Malaysia. Based on a cross-sectional sample of 2447 individuals from the Malaysia Non-Communicable Disease Surveillance-1, a multivariate sample selection system is developed and estimated, to accommodate high frequencies of daily FV consumption and the days of servings among nondaily consumers. Results indicate that the authors' attempt to account for endogenous sample selectivity and cross-equation correlations is justified. There exist positive correlations between FV consumption likelihoods and longer work hours, higher levels of education, high income, female gender, nonsmoking status, and being from East Malaysia. Among nondaily consumers, those with longer work hours, singles, and people with diabetes are less inclined to eat fruits on more days. Overall, higher-educated, affluent people, nonsmokers, and East Malaysians display more days of FV consumption. Based on these outcomes, several policy implications are recommended vis-à-vis FV consumption patterns in Malaysia.

    Concentrations of heavy metals and metalloid in borehole drinking water from 18 communities in Tarkwa, Ghana, were measured to assess the health risk associated with its consumption. Mean concentrations of heavy metals (μg/L) exceeded recommended values in some communities. If we take into consideration the additive effect of heavy metals and metalloid, then oral hazard index (HI) results raise concerns about the noncarcinogenic adverse health effects of drinking groundwater in Huniso. According to the US Environmental Protection Agency's (USEPA) guidelines, HI values indicating noncarcinogenic health risk for adults and children in Huniso were 0.781 (low risk) and 1.08 (medium risk), respectively. The cancer risk due to cadmium (Cd) exposure in adults and children in the sampled communities was very low. However, the average risk values of arsenic (As) for adults and children through drinking borehole water in the communities indicated medium cancer risk, but high cancer risk in some communities such as Samahu and Mile 7. Based on the USEPA assessment, the average cancer risk values of As for adults (3.65E-05) and children (5.08E-05) indicated three (adults) and five (children) cases of neoplasm in a hundred thousand inhabitants. The results of this study showed that residents in Tarkwa who use and drink water from boreholes could be at serious risk from exposure to these heavy metals and metalloid.

    Posttraumatic stress disorder (PTSD) patients have low cortical concentrations of γ-aminobutyric acid (GABA) and elevated glutamate (Glu) as measured by proton magnetic resonance spectroscopy (1H MRS). Alcohol use disorder (AUD) is highly comorbid with PTSD, but the neurobiological underpinnings are largely unknown. We wanted to determine if PTSD patients with AUD have normalized cortical GABA and Glu levels in addition to metabolite alterations common to AUD. We compared brain metabolite concentrations in 10 PTSD patients with comorbid AUD (PAUD) with concentrtations in 28 PTSD patients without AUD and in 20 trauma-exposed controls (CON) without PTSD symptoms. We measured concentrations of GABA, Glu, N-acetylaspartate (NAA), creatine- (Cr) and choline-containing metabolites (Cho), and myo-Inositol (mI) in three cortical brain regions using 1H MRS and correlated them with measures of neurocognition, insomnia, PTSD symptoms, and drinking severity. In contrast to PTSD, PAUD exhibited normal GABA and Glu concentrations in the parieto-occipital and temporal cortices, respectively, but lower Glu and trends toward higher GABA levels in the anterior cingulate cortex (ACC). Temporal NAA and Cho as well as mI in the ACC were lower in PAUD than in both PTSD and CON. Within PAUD, more cortical GABA and Glu correlated with better neurocognition. Heavy drinking in PTSD is associated with partially neutralized neurotransmitter imbalance, but also with neuronal injury commonly observed in AUD. PMID:25444536

    Non-daily smokers commonly smoke cigarettes following the consumption of alcohol, yet the reason(s) for this remains poorly understood. The present study examined the impact of alcohol consumption on responses in tobacco salient cues 49 male and 50 female non-daily smokers. After the administration of an alcohol, placebo, or control beverage, participants were exposed to series neutral video clips and tobacco smoking salient video clips, and their subjective states and heart rates were monitored. The timing of the exposure to the tobacco smoking clips was randomly determined to coincide with the timing of either the ascending limb or the descending limb of the blood alcohol concentration (BAC) curve of the alcohol beverage condition. The tobacco smoking clips were found to increase cigarette craving regardless of beverage condition or timing of exposure (p = .002). Alcohol consumption was associated with increased ratings of intoxication (p < .001), increased heart rate across participants (p < .001), and increased cigarette craving in female participants specifically (p = .017). Alcohol did not influence responses to the smoking videos. These results suggest that smoking salient cues and alcohol may impact cigarette craving in non-daily smokers through independent processes.

    Little has been reported on the efficacy of brief intervention (BI) among heavy episodic drinkers, although this drinking style is known to be especially harmful in relation to negative consequences including alcohol-related injuries. The comparative efficacy of BI is analyzed in two similar randomized controlled clinical trials of emergency department (ED) patients in two different cultures, both of which exhibit similar drinking styles of heavy episodic drinking: Poland and Mexican-Americans in the U.S. Improvements in drinking and problem outcomes are analyzed at 3-month and 12-month follow-up, using random effects modeling, among 446 Polish patients and 698 Mexican-American patients, randomized to screened only, assessment, and intervention conditions in each study. In Poland significant improvement was observed in all outcome measures for the assessed condition at 3-months compared to baseline, but only in the two problem variables at 12-months, while for the intervention condition, significant improvement was found in all outcome measures at both time periods; however, estimates of the interaction terms were not statistically significant. In the Mexica-American study, while significant improvement in nearly all outcome measures were observed at 3 months and 12 months for both conditions, estimates of the interaction terms suggest that for all drinking variables, but not problem variables, outcomes were significantly improved for the intervention condition over the assessed condition at 12 months, suggesting a 12-month intervention effect. Findings here are non-conclusive regarding a treatment effect of BI for heavy episodic drinking in ED patients. Given the mixed findings for BI in other ED studies, future studies need to explore the efficacy of BI in other populations and cultures exhibiting different drinking patterns to help identify what type of drinker would most benefit from BI in the ED setting.

Conversely, the risk for heavy episodic drinking may be enhanced in men who strive to demonstrate traditional notions of masculinity through risk-taking and endorsement of playboy norms (Iwamoto et al. 2010). Although this review has illustrated the contemporary state of research on alcohol use among Asian Americans, it also highlights the significant limitations in this literature. Many of the studies reviewed here have used cross-sectional data, which do not allow researchers to infer causality between the various sociocultural factors and problematic alcohol use. One way of addressing this gap in the existing literature may be to implement longitudinal designs to further understand how the temporal relationship between sociocultural factors, including acculturation and gender norms, may impact alcohol use and alcohol-related problem trajectories. There also is a pressing need to develop greater understanding of within-group differences among U.S.-born and foreign-born Asian Americans as well as among as specific ethnic groups. To date, epidemiological research has largely neglected to examine these significant discrepancies. Given the growing prevalence of alcohol use and alcohol-related problems among Asian-American women (Grant et al. 2004; Iwamoto et al. 2010), studies also should focus on this group and explore how the intersection of gender and culture may influence alcohol use. Finally, the majority of research on this population has been conducted in college samples; therefore, it is important to also examine community samples, including U.S.-born young adults who are not attending college and older adult Asian-American populations.

    Drinking groundwater is a significant pathway for human exposure to heavy metals. To evaluate the health effect of some heavy metals ingestion through the groundwater drinking pathway, the authors collected 35 groundwater samples from the drinking water wells of local residents and the exploitation wells of waterworks in Baotou, China. The monitoring results indicate that the groundwater had been polluted by heavy metals in some regions of the study area. A health risk assessment model derived from the U.S. Environmental Protection Agency was used to determine the noncarcinogenic and carcinogenic effects to residents who drink groundwater. All the respondents in the study area were at potential risk of carcinogenic health effects from arsenic when using the lowest safe standard for carcinogenic risk (1E-06). The hazard quotient values for noncarcinogenic health risk of arsenic exceeded 1 in 14.3% of the sampling wells in the study area. The research results could provide baseline data for groundwater utilization and supervision in the Baotou plain area. PMID:26867296

    The aim of this study was to investigate heavy drinking and social and health correlates in university students in low, middle income and emerging economy countries. Using anonymous questionnaires, data were collected in a cross-sectional survey of 17,590 undergraduate university students (mean age 20.8, SD 2.9) from 25 universities in 24 countries across Asia, Africa and the Americas. Overall, 71.6 % were non-drinkers, 17.1 % moderate and 11.3 % heavy alcohol drinkers (14.2 % in men and 9.2 % in women) in the past 2 weeks. In a multivariate logistic regression analysis, older age, poorer family background, living in a higher income country, weak beliefs in the importance of limiting alcohol use, higher country per capita alcohol consumption, other substance use (tobacco and illicit drug use), and poor life satisfaction was associated with heavy drinking. Addressing health beliefs and co-occurring addictive behaviors may be crucial in the prevention of heavy drinking in this population. PMID:26298475

    This study used an experimental paradigm to investigate the roles of sexual victimization history and alcohol intoxication in young women’s sexual-emotional responding and sexual risk taking. A nonclinical community sample of 436 young women, with both an instance of heavy episodic drinking and some HIV/STI risk exposure in the past year, completed childhood sexual abuse (CSA) and adolescent/adult sexual assault (ASA) measures. A majority of them reported CSA and/or ASA, including rape and attempted rape. After random assignment to a high alcohol dose (.10%) or control condition, participants read and projected themselves into an eroticized scenario of a sexual encounter involving a new partner. As the story protagonist, each participant rated her positive mood and her sexual arousal, sensation, and desire, and then indicated her likelihood of engaging in unprotected sex. Structural equation modeling analyses revealed that ASA and alcohol were directly associated with heightened risk taking, and alcohol’s effects were partially mediated by positive mood and sexual desire. ASA was associated with attenuated sexual-emotional responding and resulted in diminished risk taking via this suppression. These are the first findings indicating that, compared to non-victimized counterparts, sexually victimized women respond differently in alcohol-involved sexual encounters in terms of sexual-emotional responding and risk-taking intentions. Implications include assessing victimization history and drinking among women seeking treatment for either concern, particularly women at risk for HIV, and alerting them to ways their histories and behavior may combine to exacerbate their sexual risks.

    Despite increases in nondaily smoking among young adults, no prior research has aimed to develop and test an intervention targeting this group. Thus, we aimed to develop and test the feasibility, acceptability, and potential effectiveness of an online intervention targeting college student nondaily smokers. We conducted a one-arm feasibility and acceptability trial of a four-week online intervention with weekly contacts among 31 college student nondaily smokers. We conducted assessments at baseline (B), end of treatment (EOT), and six-week followup (FU). We maintained a 100% retention rate over the 10-week period. Google Analytics data indicated positive utilization results, and 71.0% were satisfied with the program. There were increases (P < .001) in the number of people refraining from smoking for the past 30 days and reducing their smoking from B to EOT and to FU, with additional individuals reporting being quit despite recent smoking. Participants also increased in their perceptions of how bothersome secondhand smoke is to others (P < .05); however, no other attitudinal variables were altered. Thus, this intervention demonstrated feasibility, acceptability, and potential effectiveness among college-aged nondaily smokers. Additional research is needed to understand how nondaily smokers define cessation, improve measures for cessation, and examine theoretical constructs related to smoking among this population.

    This paper models heterogeneity in the relationship between exposure to information at school or in the media and cannabis use and heavy drinking, using latent class techniques applied to data on French teenagers collected in 1993. Teenagers cluster in five classes which differ in their tastes for drunkenness and cannabis, and in the correlations between information exposure and cannabis use or heavy drinking. Teenager heterogeneity and habit-formation or precociousness effects limit the effectiveness of general information policies. Improving the impact of prevention requires that interventions be better targeted and personalised. We show how economic theory, latent class techniques and existing psychometric questionnaires can be used to build simple statistical tools for targeting prevention policies.

    Given the dynamic fluctuating nature of alcohol use among emerging adults (Del Boca, Darkes, Greenbaum, & Goldman, 2004), patterns of alcohol use were modeled across 70 days in an intensive repeated-measures diary design. Two hundred first-year college students provided 10 weekly reports of their daily alcohol consumption via computer-assisted telephone interviews. Multi-level models demonstrated large within-person variability across days in drinks consumed, binge drinking, and days exceeding self-reported limits for stumbling around and passing out; these outcome variables were predicted by weekdays vs. weekend days (within-person) and gender, age of drinking initiation, fraternity/sorority membership, and alcohol motivations (between-persons). Repeated measurement of alternate indicators of alcohol use permits the examination of novel and important questions about alcohol use and abuse particularly in young adult and other erratically drinking populations.

A total of 128 water samples from 42 different brands of bottled mineral and drinking water were collected and analysed for contamination levels of lead (Pb), cadmium (Cd), copper (Cu), arsenic (As) and mercury (Hg). Determinations were performed using a graphite furnace atomic absorption spectrophotometer for Pb, Cd and Cu, a hydride vapour generation as well as an Arsenator digital kit (Wagtech WTD, Tyne and Wear, UK) for As and a direct mercury analyser for Hg. Arsenic concentration in six bottled gaseous mineral samples was higher than the related limit. Regardless of these, mean concentrations of Pb, Cd, Cu, As and Hg in all types of water samples were 4.50 ± 0.49, 1.08 ± 0.09, 16.11 ± 2.77, 5.80 ± 1.63 and 0.52 ± 0.03 µg L⁻¹, respectively. Values obtained for analysed heavy metals in all samples were permissible according to the limits of national and international standards.

    Background Global association and experimental studies suggest that alcohol use may increase sexual behavior that poses risk for exposure to sexually-transmitted infections (STI) among heterosexual men and women. However, results from longitudinal and daily recall studies exploring the co-occurrence of alcohol use with various sexual risk outcomes in more naturalistic contexts have been mixed, and the bulk of this research has focused on college students. Methods The current study enrolled heavy-drinking emergency department (ED) patients and used a cross-sectional, 30-day Timeline Followback (TLFB) method to examine the daily co-occurrence between alcohol use and three sexual behavior outcomes: Any sex, unprotected intercourse (UI), and UI with casual partners (vs. protected intercourse [PI] with casual partners, or UI/PI with steady partners). Results Results indicated that increasing levels of alcohol use on a given day increased the odds of engaging in any sexual activity and that heavy drinking (but not very heavy drinking) on a given day was associated with an increased odds of engaging in UI with either steady or casual partners. However, day-level alcohol use was not associated with an increased odds of UI with casual partners. Conclusions These findings suggest that alcohol may play an important role in increasing risk for HIV/STIs among heterosexuals, and support the continued need to target heavy drinking in sex risk reduction interventions. However, our results also suggest that alcohol may not universally result in unprotected sex with casual partners, a behavior posing perhaps the highest risk for HIV/STI transmission. PMID:25962789

    Objective: The purpose of this study was to conduct a meta-analysis summarizing the effectiveness of brief, single-session interventions to reduce alcohol use among heavy drinking college students. Method: A comprehensive literature search identified 73 studies comparing the effects of single-session brief alcohol intervention with treatment-as-usual or no-treatment control conditions on alcohol use among heavy drinking college students. Random-effects meta-analyses with robust variance estimates were used to synthesize 662 effect sizes, estimating the average overall effect of the interventions and the variability in effects across a range of moderators. Results: An overall mean effect size of ḡ = 0.18, 95% CI [0.12, 0.24] indicated that, on average, single-session brief alcohol interventions significantly reduced alcohol use among heavy drinking college students relative to comparison conditions. There was minimal variability in effects associated with study method and quality, general study characteristics, participant demo-graphics, or outcome measure type. However, studies using motivational enhancement therapy/motivational interviewing (MET/MI) modalities reported larger effects than those using psychoeducational therapy (PET) interventions. Further investigation revealed that studies using MET/ MI and feedback-only interventions, but not those using cognitive-behavioral therapy or PET modalities, reported average effect sizes that differed significantly from zero. There was also evidence that long-term effects were weaker than short-term effects. Conclusions: Single-session brief alcohol interventions show modest effects for reducing alcohol consumption among heavy drinking college students and may be particularly effective when they incorporate MET/MI principles. More research is needed to directly compare intervention modalities, to develop more potent interventions, and to explore the persistence of long-term effects. PMID:26098028

    In both clinical and forensic settings, hair analysis for ethyl glucuronide (HEtG) has been increasingly employed for diagnosing chronic excessive drinking and, more recently, for monitoring abstinence. This paper aims at meta-analysing published data on HEtG concentrations in teetotallers, social drinkers and heavy drinkers in order to evaluate the use of this marker in hair for identifying chronic excessive drinking and for monitoring abstinence. In May 2012, a systematic multi-database search retrieved 366 records related to HEtG and further screened for relevant publications in the field. Fifteen (4.1 %) records matched the selection criteria and were included in the meta-analysis. The mean and 95 % confidence intervals (CI) of HEtG concentrations in social drinkers (mean 7.5 pg/mg; 95 % CI 4.7-10.2 pg/mg; p < 0.001), heavy drinkers (mean 142.7 pg/mg; 95 % CI 99.9-185.5 pg/mg; p < 0.001) and deceased subjects with a known history of chronic excessive drinking (mean 586.1 pg/mg; 95 % CI 177.2-995.0 pg/mg; p < 0.01) were calculated. The ranges of mean values and 95 % confidence intervals for single studies involving teetotallers/social or social/heavy drinkers showed a partial overlap with a down-trespassing of both the 7 and 30 pg/mg thresholds for social and heavy drinkers, respectively. Although larger and well-designed population studies are required to draw any definitive conclusion, our data show that the cut-off of 30 pg/mg limits the false-negative effect in differentiating heavy from social drinkers, whereas the recently proposed 7 pg/mg cut-off value might only be used for suspecting an active alcohol use, and not for proving complete abstinence.

    This study tested the effect of marriage on young adult heavy drinking and tested whether this effect was mediated by involvement in social activities, religiosity, and self-control reasons for limiting drinking. The sample of 508 young adults was taken from an ongoing longitudinal study of familial alcoholism that over-sampled children of alcoholics (Chassin, Rogosch, & Barrera, 1991). In order to distinguish role socialization effects of marriage from confounding effects of role selection into marriage, analyses used both the analysis of covariance (ANCOVA) method and the change score method of adjusting for pre-marriage levels of heavy drinking and the mediators. Results showed role socialization effects of marriage on post-marriage declines in heavy drinking. This effect was mediated by involvement in social activities such that marriage predicted decreased involvement in social activities, which in turn predicted decreased heavy drinking. There were no statistically significant mediated effects of religiosity. The mediated effect of self-control reasons for limiting drinking was supported by the ANCOVA method only, and further investigation suggested that this result was detected erroneously due to violation of an assumption of the ANCOVA method that is not shared by the change score method. Findings from this study offer an explanation for the maturing out of heavy drinking that takes place for some individuals over the course of young adulthood. Methodologically, results suggest that the ANCOVA method should be employed with caution, and that the change score method is a viable approach to confirming results from the ANCOVA method.

    The effectiveness of cognitive-affective stress management training (SMT) as a drinking reduction program for heavy social drinking college students was investigated. The SMT package included muscle relaxation and meditation training, cognitive restructuring, and coping skill rehearsal during induced affect. Treated and control subjects rated the frequency and intensity of their anxiety, anger and depression and recorded their alcohol consumption on a daily basis over a 6-month period. SMT significantly reduced posttreatment daily anxiety ratings and was associated with changes in four of ten irrational beliefs and a shift toward more internal locus of control in treated subjects. Reduction in anxiety was no longer evident at the 2 1/2- and 5 1/2-month follow-ups. The men in the SMT group showed a significant decrease in daily drinking rates at posttreatment and at the 2 1/2-month follow-up, but drinking returned to baseline levels by 5 1/2 months for the group as a whole. However, significant improvement variance in daily moods and in drinking rates over all posttreatment periods was accounted for by individual difference variables in the trained subjects but not in the control group, suggesting that these cognitive, personality, and social support variables are associated with response to stress management training. Implications of these results for future prevention research are discussed.

    Human beings are frequently exposed to pathogens and heavy metals through ingestion of contaminated drinking water throughout the world particularly in developing countries. The present study aimed to assess the quality of water used for drinking purposes in Malakand Agency, Pakistan. Water samples were collected from different sources (dug wells, bore wells, tube wells, springs, and hand pumps) and analyzed for different physico-chemical parameters and bacterial pathogens (fecal coliform bacteria) using standard methods, while heavy metals were analyzed using atomic absorption spectrophotometry (AAS-PEA-700). In the study area, 70 % of water sources were contaminated with F. coliform representing high bacterial contamination. The heavy metals, such as Cd (29 and 8 %), Ni (16 and 78 %), and Cr (7 %), exceeded their respective safe limits of WHO (2006) and Pak-EPA (2008), respectively, in water sources, while Pb (9 %) only exceeded from WHO safe limit. The risk assessment tools such as daily intake of metals (DIMs) and health risk indexes (HRIs) were used for health risk estimation and were observed in the order of Ni > Cr > Mn > Pb > Cd and Cd > Ni > Pb > Mn > Cr, respectively. The HRI values of heavy metals for both children and adults were <1, showing lack of potential health risk to the local inhabitants of the study area. PMID:27075311

    Objective . Aboriginal people in Canada are at higher risk to heavy alcohol consumption than are other Canadians. The objective of this study was to examine a set of culturally specific correlates of heavy drinking among First Nations and Métis youth and adults. Methods . Demographic, geographic, socioeconomic and health-related variables were also considered. Data were used from Statistics Canada's 2012 Aboriginal Peoples Survey to predict heavy drinking among 14,410 First Nations and Métis 15years of age and older. Separate sets of binary sequential logistic regression models were estimated for youth and adults. Results . Among youth, those who had hunted, fished or trapped within the last year were more likely to be heavy drinkers. In addition, current smokers and those who most frequently participated in sports were at higher odds of heavy alcohol consumption. Among adults, respondents who had hunted, fished or trapped within the last year were more likely to drink heavily. On the other hand, those who had made traditional arts or crafts within the last year were less likely to drink heavily. Conclusions . Men, younger adults, smokers, those who were unmarried, those who had higher household incomes, and those who had higher ratings of self-perceived health were more likely to be heavy drinkers. Efforts aimed at reducing the prevalence of heavy drinking among this population may benefit from considering culturally specific factors, in addition to demographic variables and co-occurring health-risk behaviors.

    This article estimates the effects of heavy alcohol consumption on Social Security Old-Age and Survivor Insurance (OASI) contributions and benefits. The analysis accounts for differential earnings and mortality experiences of individuals with different alcohol consumption patterns and controls for other characteristics, including smoking. Relative to moderate drinkers, heavy drinkers receive fewer OASI benefits relative to their contributions. Ironically, for each cohort of 25-year-olds, eliminating heavy drinking costs the program an additional $3 billion over the cohort's lifetime. Public health campaigns are designed to improve individual health-relevant behaviors and, in the long run, increase longevity. Therefore, if programs for the elderly are structured as longevity-independent defined benefit programs, their success will reward healthier behaviors but increase these programs’ outlays and worsen their financial condition.

    Contamination of drinking water by arsenic and other heavy metals and their related toxicology is a serious concern now-a-days. Millions of individual world-wide are suffering from the arsenic and other heavy metal related diseases due to the consumption of contaminated groundwater. 60 water samples from different sources of 6 small tea gardens of Sonitpur district were collected to study the potability of water for drinking purposes. The water samples collected from sources like tube wells, ring wells and ponds were analyzed for arsenic, heavy metals like iron, manganese and mercury with sodium, potassium, calcium, magnesium, pH, total hardness, chloride, fluoride and sulphate. Some drain water samples of the tea garden areas were also collected to analyze the above mentioned water parameters to see the contamination level. Experiments revealed that 78% samples of total collection had arsenic content above the permissible limit (0.01 ppm) of WHO guideline value for drinking water. The highest arsenic was observed 0.09 ppm at one sample of Gobindra Dahal tea garden of Gohpur sub division of Sonitpur district. 94% samples had contamination due to manganese 39% samples had iron and 44% samples had Hg. The water quality data was subjected to some statistical treatments like NDA, cluster analysis and pearson correlation to observe the distribution pattern of the different water quality parameters. A strong pearson correlation coefficient was observed between parameters-arsenic and manganese (0.865) and arsenic and mercury (0.837) at 0.01 level, indicated the same sources of drinking water contamination.

    Objective This study examines racial differences between Caucasians and African Americans in the association of parenting style typologies with changes in heavy episodic drinking from adolescence to young adulthood. Methods The analytic sample consists of 9,942 adolescents drawn from the National Longitudinal Study of Adolescent Health, which followed respondents from ages 12 to 31 years. Confirmatory factor analysis and factor mixture modeling are used to classify parenting style typologies based on measures of parental acceptance and control. HED trajectories are evaluated using a zero-inflated Poisson multigroup latent growth curve modeling approach. Results The mixture model identified four heterogeneous groups that differed based on the two latent variables (parental acceptance and control): balanced (65.8% of the sample), authoritarian (12.2%), permissive (19.4%), and uninvolved/neglectful (2.7%). Regardless of race, we found that at age 12 years, children of authoritarian parents have a higher probability of not engaging in HED than children of parents with balanced, permissive, or neglectful parenting styles. However, among African American youth who reported HED at age 12, authoritarian parenting was associated with greater level of HED at age 12 but a less steep increase in level of HED as age increased yearly as compared with balanced parenting. For Caucasian adolescents, uninvolved, permissive, and authoritarian parenting were not associated with a greater level of HED as age increased yearly as compared with adolescents exposed to balanced parenting. Conclusion The influence of parenting styles on HED during adolescence persists into young adulthood and differs by race for youth engaging in HED. PMID:25222086

    Objective Given widespread alcohol misuse among college students, numerous intervention programs have been developed, including personalized normative feedback (PNF). Most research evaluating PNF assumes that presenting one's own perceived norms is necessary to correct normative misperceptions and thereby reduce drinking. Alternatively, simply providing social comparison information showing that one drinks more than others may be sufficient. The present study evaluated the efficacy of full PNF (one's own drinking, campus drinking rates, and perceived norms) and a partial personalized social comparison feedback (PSCF; one's own drinking and campus drinking rates) in a randomized trial among heavy-drinking college students. Method Participants included 623 heavy-drinking students from three universities. Assessments occurred at baseline and three- and six-months post-baseline. Results Primary analyses examined differences across four drinking outcomes (drinks per week, total drinks past month, frequency of past month drinking, and negative alcohol-related consequences) at three- and six-month follow-ups controlling for the baseline variable. Results revealed significant reductions across all alcohol consumption outcomes at three months in both intervention conditions compared to attention-control. Mediation analyses demonstrated significant indirect effects of the intervention on six-month drinking through changes in perceived norms at three months. Moreover, evidence emerged for changes in drinking at three months as a mediator of the association between PSCF and six-month perceived norms. Conclusions The present research suggests PNF may not require explicit consideration of one's perceived norms in order to be effective and that direct social comparison provides an alternative theoretical mechanism for PNF efficacy.

    This study examines the sociodemographic factors associated with daily fruit and vegetable (FV) consumption in Malaysia. Based on a cross-sectional sample of 2447 individuals from the Malaysia Non-Communicable Disease Surveillance-1, a multivariate sample selection system is developed and estimated, to accommodate high frequencies of daily FV consumption and the days of servings among nondaily consumers. Results indicate that the authors' attempt to account for endogenous sample selectivity and cross-equation correlations is justified. There exist positive correlations between FV consumption likelihoods and longer work hours, higher levels of education, high income, female gender, nonsmoking status, and being from East Malaysia. Among nondaily consumers, those with longer work hours, singles, and people with diabetes are less inclined to eat fruits on more days. Overall, higher-educated, affluent people, nonsmokers, and East Malaysians display more days of FV consumption. Based on these outcomes, several policy implications are recommended vis-à-vis FV consumption patterns in Malaysia. PMID:23007483

    The study assessed levels of heavy metals in drinking water sources in two small-scale mining communities (Nangodi and Tinga) in northern Ghana. Seventy-two (72) water samples were collected from boreholes, hand dug wells, dug-out, and a stream in the two mining communities. The levels of mercury (Hg), arsenic (As), lead (Pb), zinc (Zn), and cadmium (Cd) were determined using an atomic absorption spectrophotometer (AAS). Mean levels (mg/l) of heavy metals in water samples from Nangodi and Tinga communities were 0.038 and 0.064 (Hg), 0.031 and 0.002 (As), 0.250 and 0.031 (Pb), 0.034 and 0.002 (Zn), and 0.534 and 0.023 (Cd), respectively, for each community. Generally, levels of Hg, As, Pb, Zn, and Cd in water from Nangodi exceeded the World Health Organisation (WHO) stipulated limits of 0.010 for Hg, As, and Pb, 3.0 for Zn and 0.003 for Cd for drinking water, and levels of Hg, Pb, and Cd recorded in Tinga, exceeded the stipulated WHO limits. Ingestion of water, containing elevated levels of Hg, As, and Cd by residents in these mining communities may pose significant health risks. Continuous monitoring of the quality of drinking water sources in these two communities is recommended.

    In the Netherlands, young adults' drinking practices have become an issue of public concern since their drinking levels are high. Heavy drinking can place young adults at an increased risk for developing short- and long-term health-related problems. Current national alcohol prevention programmes focus mainly on adolescents and their parents and paying less systematic attention to young adults. The present study describes the theory and evidence-based development of a web-based brief alcohol intervention entitled What Do You Drink (WDYD). We applied the Intervention Mapping (IM) protocol to combine theory and evidence in the development and implementation of WDYD. The WDYD intervention aims to detect and reduce heavy drinking of young adults who are willing to decrease their alcohol consumption, preferably below the Dutch guidelines of low-risk drinking. According to the IM protocol, the development of WDYD resulted in a structured intervention. Reducing heavy drinking to low-risk drinking was proposed as the behavioural outcome. Motivational interviewing principles and parts of the I-Change Model were used as methods in the development of WDYD, whereas computer tailoring was selected as main strategy. An effect and a process evaluation of the intervention will be conducted. IM was found to be a practical instrument for developing the WDYD intervention tailored to a specific target population in the area of alcohol prevention.

    Young adults are at risk for initiation of tobacco use and progression to tobacco dependence. Not every person who smokes cigarettes becomes tobacco dependent, however, and non-daily smoking is becoming more prevalent among those who use tobacco. It is likely that individual differences in psychosocial and behavioral factors influence risk for engaging in non-daily and daily cigarette smoking. The objective of this study was to investigate the associations between impulsivity and smoking status in young adults who vary in frequency of cigarette smoking. Young adult first-year college students between the ages of 18-24 (512) were classified to one of three groups: non-smokers, non-daily smokers, or daily smokers, and impulsivity was assessed using the UPPS-P (negative and positive urgency, lack of premeditation, lack of perseverance, sensation seeking). When all impulsivity dimensions were used simultaneously to predict smoking status, negative urgency predicted increased risk of membership in the daily smoking group and lack of premeditation predicted increased risk of membership in the non-daily smoking group. These results suggest that dimensions of impulsivity may contribute differentially to forms of smoking behavior in young adults.

    Rainwater samples harvested for drinking from the west part of Hebron (south of West Bank in Palestine), the largest city in the West Bank, were analyzed for the content of different trace heavy metals (Cr, Mn, Co, Ni, Cu, Zn, Mo, Ag, Cd, Bi, and Pb) by inductively coupled plasma mass spectrometry (ICP-MS). This study was conducted to determine the water quality of harvested rainwater used for drinking of south West Bank (case study, Hebron area). A total of 44 water samples were collected in November 2012 from 44 house cisterns used to collect rainwater from the roofs of houses. The samples were analyzed for their pH, temperature, electrical conductivity, total dissolved solids, and different heavy metal contents. The pH of all water samples was within the US Environmental Protection Agency limits (6.5-8.5), while some water samples were found to exceed the allowed WHO limit for total dissolved solids (TDSs) in drinking water. Results showed that concentrations of the heavy metals vary significantly between the 44 samples. Results also showed that the concentration of five heavy metals (Cr, Mn, Ni, Ag, and Pb) is higher than the WHO limits for these heavy metals in drinking water. Overall, our findings revealed that harvested rainwater used for drinking of this part of south West Bank is contaminated with heavy metals that might affect human health.

    The decisional balance, a brief detailing of the advantages and disadvantages of behavior change, serves as a key component to interventions in Motivational Interviewing. The impact of this component alone is not well understood. Forty-seven men completed a Timeline Followback interview assessing alcohol consumption and unsafe sexual practices. They then completed a decisional balance, listing the Pros and Cons of decreasing their drinking, but not one for safer sex. One-month follow-up data showed that they had statistically significant and clinically meaningful increases in their motivation to alter drinking and decreases in the number of drinks that they intended to drink, the actual drinks consumed per month, the days per month that they drank, their maximum number of drinks consumed on one occasion, and their average number of drinks per occasion. They did not alter their sexual behavior or their motivation to increase safe sex behavior. These results suggest that the decisional balance plays an important role in Motivational Interviewing and could serve as a quick and efficient intervention by itself. PMID:15970393

    Background Identifying novel ways to recruit smokers for treatment studies is important. In particular, certain subgroups of adult smokers, such as heavy-drinking smokers, are at increased risk for serious medical problems and are less likely to try quitting smoking, so drawing this hard-to-reach population into treatment is important for improving health outcomes. Objective This study examined the utility of Facebook advertisements to recruit smokers and heavy-drinking smokers for treatment research and evaluated smoking and alcohol use and current treatment goals among those who responded to the Web-based survey. Methods Using Facebook’s advertising program, 3 separate advertisements ran for 2 months targeting smokers who were thinking about quitting. Advertisements were shown to adult (at least 18 years of age), English-speaking Facebook users in the greater New Haven, Connecticut, area. Participants were invited to complete a Web-based survey to determine initial eligibility for a smoking cessation research study. Results Advertisements generated 1781 clicks and 272 valid, completed surveys in 2 months, with one advertisement generating the most interest. Facebook advertising was highly cost-effective, averaging $0.27 per click, $1.76 per completed survey, and $4.37 per participant meeting initial screening eligibility. On average, those who completed the Web-based survey were 36.8 (SD 10.4) years old, and 65.8% (179/272) were female. Advertisements were successful in reaching smokers; all respondents reported daily smoking (mean 16.2 [SD 7.0] cigarettes per day). The majority of smokers (254/272, 93.4%) were interested in changing their smoking behavior immediately. Many smokers (161/272, 59.2%) also reported heavy alcohol consumption at least once a month. Among smokers interested in reducing their alcohol use, more were heavy drinkers (45/56, 80.4%) compared to non-heavy drinkers (11/56, 19.6%; χ2[1,N=272]=13.0, P<.001).

    BACKGROUND Epidemiological research on alcohol-related harm has long given priority to studies on harm to the drinker. A limitation with this perspective is that it neglects the harm drinking causes to people around the drinker, and thus, it fails to give a full picture of alcohol-related harm in society. AIM The aim was to compare the prevalence and correlates of experiencing harm from the heavy drinking by family and friends across the Nordic countries and Scotland and to discuss whether potential differences match levels of drinking, prevalence of binge drinking, and alcohol-related mortality. DATA AND METHOD Data from recent national general population surveys with similar questions on experiences of harms from the drinking of family and friends were collected from Sweden, Finland, Denmark, Norway, Iceland, and Scotland. RESULTS National estimates of the overall population prevalence of harm from the drinking of family and friends ranged from 14% to 28% across these countries, with the highest prevalence in Finland, Iceland, and Norway and lower estimates for Denmark, Sweden, and Scotland. Across all countries, the prevalence of harm from heavy drinking by family and friends was significantly higher among women and young respondents. CONCLUSION This study revealed large differences in the prevalence of harm across the study countries, as well as by gender and age, but the differences do not match the variation in population drinking and other indicators of harm. The implications of the findings for future research are discussed. PMID:26884681

    An emerging literature suggests that temporary deficits in the ability to inhibit impulsive urges may be proximally associated with intimate partner aggression. The current study examined the experience of alcohol use and the depletion of self-control in the prediction of relationship functioning. Daily diary data collected from 118 heterosexual couples were analyzed using parallel multi-level Actor Partner Interdependence Models to assess the effects of heavy episodic drinking and depletion of self-control across partners on outcomes of participant-reported daily arguing with and anger toward an intimate partner. Heavy episodic drinking among actors predicted greater arguing but failed to interact with either actor or partner depletion. We also found that greater arguing was reported on days of high congruent actor and partner depletion. Both actor and partner depletion, as well as their interaction, predicted greater partner-specific anger. Greater partner-specific anger was generally reported on days of congruent actor and partner depletion, particularly on days of high partner depletion. The current results highlight the importance of independently assessing partner effects (i.e., depletion of self-control), which interact dynamically with disinhibiting actor effects, in the prediction of daily adverse relationship functioning. Results offer further support for the development of prospective individualized and couples-based interventions for partner conflict. PMID:24700558

    Men who have sex with men (MSM) account for the largest proportion of new HIV infections in the United States. Alcohol may facilitate HIV transmission by increasing unprotected anal sex, but few studies have focused on transmission behaviors in HIV-positive MSM. This study explored daily associations between alcohol use and sexual behavior among heavy drinking HIV-positive MSM using a 30-day Timeline Followback interview. Results of generalized estimating equations indicated that greater alcohol consumption on a given day was associated with a linear increase in the odds of having unprotected anal sex with partners of any HIV status. However, the odds of reporting unprotected anal sex with HIV-negative or HIV-status unknown partners increased in a curvilinear fashion, occurring primarily at very heavy levels of use (12+ drinks). Results suggest that very heavy drinking increases the risk of engaging in sexual behavior that has the potential for transmitting HIV to other men. PMID:25194967

    This study tested the effect of marriage on young adult heavy drinking and tested whether this effect was mediated by involvement in social activities, religiosity, and self-control reasons for limiting drinking. The sample of 508 young adults was taken from an ongoing longitudinal study of familial alcoholism that over-sampled children of alcoholics (Chassin, Rogosch, & Barrera, 1991). In order to distinguish role socialization effects of marriage from confounding effects of role selection into marriage, analyses used both the analysis of covariance (ANCOVA) method and the change score method of adjusting for pre-marriage levels of heavy drinking and the mediators. Results showed role socialization effects of marriage on post-marriage declines in heavy drinking. This effect was mediated by involvement in social activities such that marriage predicted decreased involvement in social activities, which in turn predicted decreased heavy drinking. There were no statistically significant mediated effects of religiosity. The mediated effect of self-control reasons for limiting drinking was supported by the ANCOVA method only, and further investigation suggested that this result was detected erroneously due to violation of an assumption of the ANCOVA method that is not shared by the change score method. Findings from this study offer an explanation for the maturing out of heavy drinking that takes place for some individuals over the course of young adulthood. Methodologically, results suggest that the ANCOVA method should be employed with caution, and that the change score method is a viable approach to confirming results from the ANCOVA method.

    We have built a high-resolution differential surface plasmon resonance (SPR) sensor for heavy metal ion detection. The sensor surface is divided into a reference and sensing areas, and the difference in the SPR angles from the two areas is detected with a quadrant cell photodetector as a differential signal. In the presence of metal ions, the differential signal changes due to specific binding of the metal ions onto the sensing area coated with properly selected peptides, which provides an accurate real-time measurement and quantification of the metal ions. Selective detection of Cu2+ and Ni2+ in the ppt-ppb range was achieved by coating the sensing surface with peptides NH2-Gly-Gly-His-COOH and NH2-(His)6-COOH. Cu2+ in drinking water was tested using this sensor.

    Alcohol misuse is increasing in Southeast Asia. We investigated the extent of and risk factors for alcohol use disorder (AUD) and heavy episodic drinking (HED) in a rural community in Cambodia. We also attempted to explore the communities' perception of alcohol misuse and elicited potential community-based strategies to address the alcohol problem. A mixed-methods study design was used, combining a cross-sectional questionnaire survey with qualitative interviews (focus group discussions and key informant interviews). AUD and HED were measured using the AUDs Identification Test Alcohol Consumption questionnaire. The prevalence of AUD and HED was high: 25% and 31%, respectively. Male sex, younger age, and increasing income were significant risk factors. The communities were well aware of the harmful effects of alcohol, expressed the importance of implementing community-based measures, and proposed various community-led solutions. Evidence-based strategies that are culturally appropriate, accepted, and driven by communities are urgently needed.

    This study was carried out in Biyang County, located in the junction of Yangtze river and Huaihe river. Drinking water samples of 20 sites in urban and rural areas in this county were collected to measure 14 heavy metals by ICP/MS. About 2 500 subjects with different age and sex were selected to measure exposure factors. Time-activity of drinking water by ingestion and dermal contact of each individual subject during the last three days were kept in dairy in detail by questionnaires. Intake of drinking water from direct and indirect consumption of water and time duration of dermal contact to water in each individual subject were kept in record based on real time measurements. Human health risks were assessed and sensitivity of exposure factors and uncertainty of risks were also analyzed. The results showed that the average drinking water intake rate of male and female are 2276 mL/d, 2265 mL/d in urban adults and 2464 mL/d, 2170 mL/d in rural adults respectively. Body surface area of male and female are 1.806 m2, 1.641 m2 in urban adults and 1.747 m2, 1.617 m2 in rural adults respectively. The contents of 14 heavy metals in this study area are all below the national drinking water standards. Cancer risks from exposure to As are ranged from 2.5 x 10(-6) to 5.2 x 10(-6) through ingestion and 1.1 x 10(-7) to 2.3 x 10(-7) through dermal exposure. Non-cancer risks are ranged from 2.1 x 10(-7) to 1.7 x 10(-6) through ingestion and 1.0 x 10(-8) to 6.0 x 10(-8) through dermal exposure. Non-cancer risks in rural population are 2.1 times to 5.6 times to the risks in urban populations. However all the risks are below the acceptable level. The sensitivity of various exposure factors including drinking water intake rate, dermal exposure time and body surface area are 71.5%. This indicates that exposure factors play a very important role in health risk assessment. Health risks in this research based on real measurement of exposure factors are about 0.94 time to 6.33 times higher

    Purpose To examine whether associations between perceived discrimination and heavy episodic drinking (HED) varies by age and by discrimination type (e.g., racial, age, physical appearance) among African American youth. Methods National data from the Panel Study of Income Dynamics Transition to Adulthood Study were analyzed. Youth participated in up to four interviews (2005, 2007, 2009, 2011; n=657) between ages 18–25. Respondents reported past-year engagement in HED (4 or more drinks for females, 5 or more drinks for males), and frequency of discriminatory acts experienced (e.g., receiving poor service, being treated with less courtesy). Categorical latent growth curve models, including perceived discrimination types (racial, age, and physical appearance) as a time-varying predictors of HED, were run in MPlus. Controls for gender, birth cohort, living arrangement in adolescence, familial wealth, parental alcohol use, and college attendance were explored. Results The average HED trajectory was curvilinear (increasing followed by flattening), while perceived discrimination remained flat with age. In models including controls, odds of HED were significantly higher than average around ages 20–21 with greater frequency of perceived racial discrimination; associations were not significant at other ages. Discrimination attributed to age or physical appearance was not associated with HED at any age. Conclusions Perceived racial discrimination may be a particularly salient risk factor for HED around the ages of transition to legal access to alcohol among African American youth. Interventions to reduce discrimination or its impact could be targeted before this transition to ameliorate the negative outcomes associated with HED. PMID:26499858

    Aims: To describe inconsistencies in reporting past-year drinking status and heavy drinking occasions (HDOs) on single questions from two different instruments, and to identify associated characteristics and impacts. Methods: We compared computer-presented Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) with categorical response options, and mental health interview (MHI) with open-ended consumption questions, completed on the same day. Participants were 464 men and 459 women aged 38 (91.7% of surviving birth cohort members). Differences in dichotomous single-item measures of abstention and HDO frequency, associations of inconsistent reporting with sex, socioeconomic status (SES) and survey order, and impacts of instrument choice on associations of alcohol with sex and SES were examined. Results: The AUDIT-C drinking frequency question estimated higher past-year abstention prevalence (AUDIT = 7.6%, MHI = 5.4%), with one-third of AUDIT-C abstainers being MHI drinkers. Only AUDIT-C produced significant sex differences in abstainer prevalence. Inconsistencies in HDO classifications were bidirectional, but with fewer HDOs reported on the MHI than AUDIT-C question. Lower SES was associated with inconsistency in abstention and weekly+ HDOs. Abstention and higher HDO frequency were associated with lower SES overall, but sex-specific associations differed by instrument. Conclusions: In this context, data collection method affected findings, with inconsistencies in abstention reports having most impact. Future studies should: (a) confirm self-reported abstention; (b) consider piloting data collection methods in target populations; (c) expect impacts of sex and SES on measurements and analyses.

    Impulsivity is a multifaceted construct that has been linked to dysregulated eating and problematic alcohol use. The UPPS model identifies five personality-based impulsivity traits that have unique predictive utility: Negative Urgency, Perseverance, Premeditation, Sensation Seeking, and Positive Urgency. Delayed reward discounting (DRD) is an index of impulsive decision making characterized by preference for smaller immediate gains at the cost of larger delayed gains. In the current study, we sought to refine the influence of impulsive personality traits and DRD on disordered eating patterns and problematic drinking. One hundred and eight treatment-seeking heavy drinkers were assessed for UPPS impulsivity traits, DRD, disordered eating, alcohol use, and demographic information. With regard to disordered eating patterns, DRD predicted higher levels of Dietary Restraint and Weight and Shape Concerns. Negative Urgency predicted binge eating and Weight and Shape Concerns. Positive Urgency predicted Eating Concerns. Female sex predicted Eating, Weight, and Shape Concerns. When considering problematic alcohol use, only Negative Urgency and Sensation Seeking were predictive. This is the first study to examine both personality-based impulsivity and DRD in relation to pathological eating and drinking behavior. The results suggest the importance of disentangling the contributions of various impulsivity constructs on dysregulated eating. PMID:24816318

    The present study was conducted to investigate the physico-chemical characteristics in drinking water of Mardan District, Pakistan. Furthermore, water quality was evaluated for the risk assessment of arsenic and heavy metals (HMs) and their contamination sources. Representative groundwater samples of shallow and deep sources were collected in the study area. These samples were analyzed for physical parameters, anions, light metals (LMs) and HMs. Results were compared with the drinking water guideline values set by the World Health Organization and the US Environmental Protection Agency. Average concentrations of anions, LMs and HMs were found within the maximum allowable contaminant levels except for bicarbonates, Fe, Cu, and Pb. Results revealed that hazard quotients >1 were observed for shallow groundwater for 10% samples only, suggesting potential health risk from water consumption. Correlation analysis and principal component analysis showed a relationship among various physico-chemical parameters in both shallow and deep groundwater. Statistical analyses suggested the geogenic and anthropogenic sources for possible enhancement of various physico-chemical parameters in the aquifer system of the study area. PMID:26608769

    There is a need for longitudinal research to understand how psychopathology relates to the onset and maintenance of substance use from adolescence into young adulthood. Hence, we investigate the longitudinal, reciprocal influences of internalizing (anxiety and depression) and externalizing (oppositional defiance) symptoms on heavy episodic drinking (HED; ≥5 drinks per occasion) and alcohol-related harms in a community-based sample of youth aged 12–27 years. Participants were chosen from the Victoria Healthy Youth Survey, followed six times, biennially between 2003 and 2013 (N = 662). Analyses used cross-lagged panel models to examine reciprocal relations over time. Differences across age and sex were also tested. Defiance symptoms predicted increases in HED, which reciprocally predicted increases in defiance symptoms for females. Internalizing symptoms were related to HED within time for females. Alcohol-related harms had reciprocal positive associations with internalizing and defiance symptoms for both males and females. Associations were largely invariant across age groups, suggesting that the presence and strength of associations persisted across development. While psychopathology preceded the onset of HED and harms, the overall findings suggest that these risk processes are mutually reinforcing across development and that youth may become entrenched in an interdependent cycle that significantly increases their risk of comorbid disorders in adulthood.

    This study analyzed whether discrepant (husband or wife use only) or concordant (both partners use) patterns of heavy drinking, marijuana use, and smoking are associated with increased risk for male-to-female partner violence and female-to-male partner violence among adult couples. Based on a geographic sample of married or cohabiting couples residing in 50 California cities, logistic regression analyses were conducted using dyadic data on past-year partner violence, binge drinking and frequency of intoxication, marijuana use, and smoking. When all substance use patterns were included simultaneously, wife-only heavy drinking couples were at elevated risk for male-to-female partner violence, as were concordant marijuana-using couples. Husband-only marijuana discrepant couples were at increased risk for female-to-male partner violence. Further research is needed to explore the processes by which discrepant and concordant substance use patterns may contribute to partner aggression.

    We examined predictors for age at onset of first alcohol use and onset of heaviest alcohol use among men (n = 43) and women (n = 46) with alcohol dependence and PTSD, PTSD only, alcohol dependence only, and controls, with a particular focus on individuals with child versus adult trauma. Using analysis of variance procedures, results showed differences in onset of first alcohol use and heaviest drinking between childhood and adulthood trauma victims. These preliminary results indicate that behavioral mechanisms associated with alcohol use patterns between individuals with childhood and adulthood trauma are dissimilar, suggesting greater psychopathological consequences for individuals with childhood trauma.

    Nondaily, or intermittent smokers (ITS), represent a growing pattern in adult smoking that needs to be explained by models of drug dependence. ITS regularly and voluntarily abstain from smoking, yet have difficulty quitting. We examine potential accounts of ITS' smoking by exploring their experience of craving and withdrawal on the days they abstain. For 3 weeks, 146 ITS and 194 daily smokers used the Ecological Momentary Assessment (EMA) to monitor craving, withdrawal, and smoking in real-time. ITS' craving (p < .001) and arousal (p < .001) were significantly lower on the 34.4% of days when they abstained (compared with days they smoked), and they experienced no increases in withdrawal symptoms. ITS who abstained for longer experienced lower craving, even on their first day of abstinence (p < .001). Within strata defined by longest duration of abstinence (1, 2-3, 4-6, ≥7 days), craving did not change over time, demonstrating no increase as resumption of smoking approached. Craving increased only at the moment smoking resumed. Furthermore, duration of abstinence runs varied more within persons than across persons. These findings contradict the predictions of a model positing that craving recurs at fixed intervals. Findings are consistent with the hypothesis that ITS' smoking is cued or primed by particular stimuli rather than by temporal cycles. These analyses demonstrate that ITS do not experience increased craving or withdrawal on days they do not smoke, and show neither signs of classical dependence nor regular cycles of craving and smoking.

    The aim of the present study was the molecular identification of a common source of infection of Campylobacter coli in two grandparent breeder farms. Campylobacter jejuni and C. coli were isolated from well water and cloacal swabs from grandparent chickens. Colonies were genotyped using restriction fragment length polymorphism-flaA gene, pulsed field gel electrophoresis and multi-locus sequence typing. The same genotype of C. coli was found in both farms and in the well from which drinking water was supplied to the farms. The well water was epidemiologically linked as the source of C. coli infection. The molecular identification for epidemiological source-tracking of C. coli in breeder farms could aid in combating the colonization of this pathogen and therefore to reduce their incidence in human campylobacteriosis.

The Turkish cities of Trabzon, Rize, and Giresun in the eastern Black Sea region were chosen as the study areas. Cancer registry data, population information, heavy metal chemical analysis results for drinking water, and other spatial information for the region were collected in a database designed in GIS. Information on a total of 13,012 registered cancer cases from the years 2000-2007 was obtained from a cancer record center and depicted spatially on a map. The incidence values explaining cancer density in residential units were calculated. Chemical analyses were then conducted to determine the presence of 17 different heavy metals by collecting a total of 541 drinking water samples. It was determined that among the 17 analyzed heavy metals, beryllium, nickel, antimony, and molybdenum had a significant relationship with cancer incidence values in the residential units.

    The six heavy metal concentrations (Cr, Cr, As, Cd, Cu, Zn and Pb) in water samples collected from five reservoirs of Liao River Basin were studied. The health risk assessment for heavy metals pollution in reservoirs was conducted based on the environmental health risk assessment model recommended by U. S. Environmental Protection Agency. The results showed that the average concentrations of Cr, Cu, Zn, As, Cd and Pb in five reservoirs of Liao River Basin were 3.36, 1.03, 2. 70, 1.23, 0. 02 and 0. 03 microg L-1, respectively. In fact, these heavy metals concentrations were obviously lower than the Standard of National Drinking Water in China (GB 5749-2006). The results also showed that the metal carcinogenic risk was relatively high in this region. The order of the risk level of carcinogenic metals was Cr>As>Cd. The highest carcinogenic risk was from Cr, with the risk for adults ranging from 4. 50 X 10(-5) approximately 7. 53 X 10(-5) a-1' and the risk for children ranging from 6. 29 X 10(-5) to 1. 05 X 10(-4) a-1. The health risk levels caused by non-carcinogenic metals ranging from 10-13 to 10(-10) a-1 were lower than the acceptable range suggested by International Commission on Radiological Protection (ICRP) and the order of the risk level of non-carcinogenic metals was Cu>Zn>Pb. The total health risk of heavy metals for adults ranging from 1. 07X 10(-4) to 1. 72X 10(-4) a-1 and for children ranging from 1. 49 X 10(-4) to 2. 40 X 10(-4) a-1 exceeded the accepted level of 5 X 10(-5) a-1 as suggested by ICRP. The health risk levels of carcinogenic metals were significantly higher than those of non-carcinogenic metals in the reservoirs for Liao River Basin.

    Pinggu District is adjacent to the county of Miyun, which contains the largest drinking water source of Beijing (Miyun Reservoir). The Wanzhuang gold field and tailing deposits are located in Pinggu, threatening Beijing's drinking water security. In this study, soil samples were collected from the surface of the mining area and the tailings piles and analyzed for physical and chemical properties, as well as heavy metal contents and particle size fraction to study the relationship between degree of pollution degree and particle size. Most metal concentrations in the gold mine soil samples exceeded the background levels in Beijing. The spatial distribution of As, Cd, Cu, Pb, and Zn was the same, while that of Cr and Ni was relatively similar. Trace element concentrations increased in larger particles, decreased in the 50-74 μm size fraction, and were lowest in the <2 μm size fraction. Multivariate analysis showed that Cu, Cd, Zn, and Pb originated from anthropogenic sources, while Cr, Ni, and Sc were of natural origin. The geo-accumulation index indicated serious Pb, As, and Cd pollution, but moderate to no Ni, Cr, and Hg pollution. The Tucker 3 model revealed three factors for particle fractions, metals, and samples. There were two factors in model A and three factors for both the metals and samples (models B and C, respectively). The potential ecological risk index shows that most of the study areas have very high potential ecological risk, a small portion has high potential ecological risk, and only a few sampling points on the perimeter have moderate ecological risk, with higher risk closer to the mining area.

    High rates of cognitive impairment persist in human immunodeficiency virus (HIV) infection, despite improved health outcomes and reduced mortality through widespread use of antiretroviral therapy (ART). Heavy alcohol use and cigarette smoking are potential contributors to neurocognitive impairment in people living with HIV (PLWH), yet few studies have examined their influence concurrently. Here we investigated the effects of self-reported alcohol use and smoking on learning, memory, processing speed, verbal fluency, and executive function in 124 HIV-positive men who have sex with men [age (mean ± SD) = 42.8 ± 10.4 years], engaged with medical care. All participants were heavy drinkers. Duration of HIV infection averaged 9.9 ± 7.6 years, and 92.7% were on a stable ART regimen. Participants completed a neuropsychological battery and assessment of past 30-day substance use. Average number of drinks per drinking day (DPDD) was 5.6 ± 3.5, and 33.1% of participants were daily smokers. Rates of neurocognitive impairment were the highest in learning (50.8%), executive function (41.9%), and memory (38.0%). Multiple regression models tested DPDD and smoking status as predictors of neurocognitive performance, controlling for age and premorbid intelligence. Smoking was significantly, negatively related to verbal learning (p = .046) and processing speed (p = .001). DPDD was a significant predictor of learning (p = .047) in a model that accounted for the interaction of DPDD and smoking status. As expected, premorbid intelligence significantly predicted all neurocognitive scores (ps < .01), and older age was associated with slower processing speed (ps < .01). In conclusion, smoking appears to be associated with neurocognitive functioning deficits in PLWH beyond the effects of heavy drinking, aging, and premorbid intelligence. Smoking cessation interventions have the potential to be an important target for improving functional outcomes

    Introduction The prognostic impact of smoking and drinking on esophageal squamous cell carcinoma (ESCC) was scarcely discussed. We investigated the prognostic value of smoking and drinking and their relationships with clinicopathological characteristics in a large cohort of patients with locoregional ESCC. Patients and methods We retrospectively analyzed 488 patients who underwent curative treatment at a single institution between January 2007 and December 2008. A chi-square test was used to evaluate the relationships between smoking and drinking and clinicopathological variables, the Kaplan–Meier method was used for 5-year overall survival (OS) and disease-free survival, and Cox proportional hazards models were applied for univariate and multivariate analyses of variables with respect to OS and disease-free survival. Results Heavy smokers were more likely to have advanced Tumor-Node-Metastases (TNM) stage and higher neutrophil/lymphocyte ratio at diagnosis (P<0.05). Drinkers were more likely to have advanced TNM stage, to present with a larger tumor, and to undergo multidisciplinary treatment (P<0.05). For patients who used neither heavy tobacco nor alcohol, used either tobacco or alcohol, and used both, the 5-year OS rates and OS times were 57.4%, 46.4%, and 39.1% (P<0.05) and not reached, 55.2 months, and 41.2 months (P<0.05), respectively. On multivariate analysis, patients who both heavily smoked and drank had 1.392 times the risk of dying during follow-up compared with neither-users (95% CI =1.020–1.901, P=0.037). Conclusion We identified that combined heavy smoking and drinking might predict poor prognosis in ESCC patients. PMID:27471400

    High rates of cognitive impairment persist in human immunodeficiency virus (HIV) infection, despite improved health outcomes and reduced mortality through widespread use of antiretroviral therapy (ART). Heavy alcohol use and cigarette smoking are potential contributors to neurocognitive impairment in people living with HIV (PLWH), yet few studies have examined their influence concurrently. Here we investigated the effects of self-reported alcohol use and smoking on learning, memory, processing speed, verbal fluency, and executive function in 124 HIV-positive men who have sex with men [age (mean ± SD) = 42.8 ± 10.4 years], engaged with medical care. All participants were heavy drinkers. Duration of HIV infection averaged 9.9 ± 7.6 years, and 92.7% were on a stable ART regimen. Participants completed a neuropsychological battery and assessment of past 30-day substance use. Average number of drinks per drinking day (DPDD) was 5.6 ± 3.5, and 33.1% of participants were daily smokers. Rates of neurocognitive impairment were the highest in learning (50.8%), executive function (41.9%), and memory (38.0%). Multiple regression models tested DPDD and smoking status as predictors of neurocognitive performance, controlling for age and premorbid intelligence. Smoking was significantly, negatively related to verbal learning (p = .046) and processing speed (p = .001). DPDD was a significant predictor of learning (p = .047) in a model that accounted for the interaction of DPDD and smoking status. As expected, premorbid intelligence significantly predicted all neurocognitive scores (ps < .01), and older age was associated with slower processing speed (ps < .01). In conclusion, smoking appears to be associated with neurocognitive functioning deficits in PLWH beyond the effects of heavy drinking, aging, and premorbid intelligence. Smoking cessation interventions have the potential to be an important target for improving functional outcomes

    Gender and living environment are two of the most consistent factors associated with heavy episodic drinking on college campuses. This study aimed to determine group differences in alcohol misuse and its attendant consequences between undergraduate women living in four distinct on-campus residential environments. A Web-based survey was self-administered to a stratified random sample of full-time students attending a large Midwestern University, and living in four distinct on-campus residential environments: 1) single-sex (all female) residential learning communities (RLCs), 2) mixed-sex (male and female) RLCs, 3) single-sex (all female) non-RLCs and 4) mixed-sex (male and female) non-RLCs. Respondents living in single-sex and mixed-sex RLCs had significantly lower rates of alcohol use, heavy episodic drinking and related primary alcohol-related consequences when compared to respondents living in non-RLCs; however, women in single-sex RLCs had the lowest rates. RLCs - particularly single-sex learning communities - appear to provide undergraduate women with an environment that supports lower rates of alcohol use and abuse. PMID:18485609

    Neuroeconomics integrates concepts and methods from psychology, economics, and cognitive neuroscience to understand how the brain makes decisions. In economics, demand refers to the relationship between a commodity's consumption and its cost, and, in behavioral studies, high alcohol demand has been consistently associated with greater alcohol misuse. Relatively little is known about how the brain processes demand decision making, and the current study is an initial investigation of the neural correlates of alcohol demand among heavy drinkers. Using an event-related functional magnetic resonance imaging (fMRI) paradigm, participants (N=24) selected how much they would drink under varying levels of price. These choices determined access to alcohol during a subsequent bar laboratory self-administration period. During decisions to drink in general, greater activity was present in multiple distinct subunits of the prefrontal and parietal cortices. In contrast, during decisions to drink that were demonstrably affected by the cost of alcohol, significantly greater activation was evident in frontostriatal regions, suggesting an active interplay between cognitive deliberation and subjective reward value. These choices were also characterized by significant deactivation in default mode network regions, suggesting suppression resulting from greater cognitive load. Across choice types, the anterior insula was notably recruited in diverse roles, further implicating the importance of interoceptive processing in decision-making behavior. These findings reveal the neural signatures subserving alcohol cost-benefit decision making, providing a foundation for future clinical applications of this paradigm and extending this approach to understanding the neural correlates of demand for other addictive commodities.

    Most local people in the agricultural areas of Hua-ruea sub-district, Ubon Ratchathani province (Thailand), generally consume shallow groundwater from farm wells. This study aimed to assess the health risk related to heavy metal contamination in that groundwater. Samples were randomly collected from 12 wells twice in each of the rainy and the dry seasons and were analyzed by inductive coupled plasma spectrometry-mass spectrometry (ICP-MS). The concentration of detected metals in each well and the overall mean were below the acceptable groundwater standard limits for As, Cd, Cr, Cu, Hg, Ni and Zn, but Pb levels were higher in four wells with an overall average Pb concentration of 16.66 ± 18.52 μg/l. Exposure questionnaires, completed by face-to-face interviews with 100 local people who drink groundwater from farm wells, were used to evaluate the hazard quotients (HQs) and hazard indices (HIs). The HQs for non-carcinogenic risk for As, Cu, Zn and Pb, with a range of 0.004-2.901, 0.053-54.818, 0.003-6.399 and 0.007-26.80, respectively, and the HI values (range from 0.10 to 88.21) exceeded acceptable limits in 58 % of the wells. The HI results were higher than one for groundwater wells located in intensively cultivated chili fields. The highest cancer risk found was 2.6 × 10(-6) for As in well no. 11. This study suggested that people living in warmer climates are more susceptible to and at greater risk of groundwater contamination because of their increased daily drinking water intake. This may lead to an increased number of cases of non-carcinogenic and carcinogenic health defects among local people exposed to heavy metals by drinking the groundwater.

    Binge drinking is a pattern of heavy drinking which is observed all over Europe. The term Binge drinking implies a lot of different meanings to different people. The most popular definition used for this term is five or more 'standard drinks' in a single occasion. Binge drinking is different from intoxication, although this kind of heavy alcohol consumption can be lead to intoxication. This condition is manifested by different signs, for example slurred speech. Binge drinking is very common among the European population. In 2006 some 80 million Europeans aged 15 plus reported this kind of alcohol consumption patterns. European surveys showed that there is an increase of binge drinking across Europe amongst young people (15-16 years) old since 1995. The consequences of binge drinking contain acute and chronic effects, which are caused by long term alcohol use. The individual risks are brain damage, suicide, sexually transmitted diseases, etc. It has also an impact on harm to others than the drinkers. This includes violence and crime, accidents, etc. Each year in the European Union 2000 homicides are related to heavy drinking. There a lot of effective measures to reduce binge drinking. Strong evidence is shown by drink-driving laws, tax, reduced access to and availability of alcohol, brief interventions such as physician advice and advertising controls. PMID:18173097

    Examining individual characteristics may not yield an understanding of the complex array of factors that affect college student alcohol use. Utilizing a latent class analysis, the present study investigated an alcohol and drug use database of first-year college students at 89 U.S. colleges and universities (N = 21,945). These data were collected between December, 2010 and September, 2011. This study identified: (1) classes based on alcohol consumption, alcohol-related behaviors, and past-year use of illegal drugs and nonmedical use of prescriptions medications (NMUPM); (2) demographic covariates of these classes; and (3) differential social norms awareness, perceived harmfulness of illegal drugs and NMUPM, and protective strategies. Four classes were identified: (1) Low Risk Drinking/Low Prevalence Drug Use (Class 1); (2) Lower Intake Drinking/Moderate Prevalence Drug Use (Class 2); (3) Moderate Risk Drinking/Moderate Prevalence Drug Use (Class 3); and (4) High Risk Drinking/High Prevalence Drug Use (Class 4). Classes differed in self-reported typical week drinking, estimated peak blood alcohol content over the past 2 weeks, high-risk alcohol use, negative alcohol-related consequences, driving under the influence or riding with drinking drivers, alcohol-related protective behaviors, and past-year substance use. Of particular interest was the identification of a latent class (Class 2) composed primarily of females with a relatively low alcohol intake, but with a high probability of past-year other substance use. This group reported negative alcohol-related consequences despite their relatively low intake. To our knowledge, this is the first latent class analysis of college student alcohol use that includes a drug use indicator and compares social norms awareness, harmfulness perceptions, and alcohol-related protective behaviors between classes.

    Previous research has found that adolescent ethanol (EtOH) exposure alters drug seeking behaviors, cognition and neuroplasticity. Using male Sprague Dawley rats, differences in spatial working memory, non-spatial discrimination learning and behavioral flexibility were explored as a function of age at the onset (mid-adolescent vs. adult) of chronic EtOH exposure (CET). Concentrations of mature brain-derived neurotrophic factor (mBDNF) and beta-nerve growth factor (β-NGF) in the prefrontal cortex and hippocampus were also assessed at different time-points: during CET, following acute abstinence (48-hrs), and after protracted abstinence (6-8 wks). Our results revealed that an adolescent onset of CET leads to increased EtOH consumption that persisted into adulthood. In both adult and adolescent onset CET groups, there were significant long-term reductions in prefrontal cortical mBDNF and β-NGF levels. However, only adult onset CET rats displayed decreased hippocampal BDNF levels. Spatial memory, assessed by spontaneous alternation and delayed alternation, was not significantly affected by CET as a function of age of drinking onset, but higher blood-EtOH levels were correlated with lower spontaneous alternation scores. Regardless of the age of onset, EtOH exposed rats were impaired on non-spatial discrimination learning and displayed inflexible behavioral patterns upon reversal learning. Our results indicate that adolescent EtOH exposure changes long-term consumption patterns producing behavioral and neural dysfunctions that persist across the lifespan. PMID:26930631

    The detection of ethyl-beta-D-6-glucuronide (EtG), a stable phase II metabolite of ethanol, is of interest in both clinical and forensic contexts with the aim of monitoring alcohol abuse. We present a liquid chromatography-electrospray ionisation-tandem mass spectrometry method for the detection and quantification of EtG in hair. Thirty milligrams of washed and cut hair were cleaned up using solid-phase extraction graphite cartridges. Separation was then performed using an Uptisphere-3SI column, and the detection was operated in the negative mode. After validation, the method was applied to hair samples taken from four fatalities (F) with documented excessive drinking habits, 12 heavy drinkers (HD) and seven social drinkers (SD). The method exhibits limits of detection and quantification of 4 and 10 pg/mg, respectively. Intra- and inter-assay standard deviation and relative bias were less than 20% over the calibrating range (10 to 3,000 pg/mg). EtG hair concentrations in SD were <10 pg/mg and >50 pg/mg for F and HD (range, 54 to 497 pg/mg). The present assay appears convenient to carry out owing to the very small quantity of hair samples required to determine an effective heavy alcohol consumption (EtG hair concentration >50 pg/mg).

    Despite previously found co-occurrence of youth gambling and alcohol use, their relationship has not been systematically explored in a national sample using DSM-based gambling measures and multivariate modeling, adjusted for potential confounders. This study aimed to empirically examine the prevalence patterns and odds of at-least-weekly alcohol use and heavy episodic drinking (HED) in relation to various levels of gambling severity in college athletes. Multivariate logistic regression analyses were performed on data from a national sample of 20,739 U.S. college athletes from the first National Collegiate Athletic Association national survey of gambling and health-risk behaviors. Prevalence of at-least-weekly alcohol use significantly increased as DSM-IV-based gambling severity increased, from non-gambling (24.5%) to non-problem gambling (43.7%) to sub-clinical gambling (58.5%) to problem gambling (67.6%). Multivariate results indicated that all levels of gambling were associated with significantly elevated risk of at-least-weekly HED, from non-problem (OR = 1.25) to sub-clinical (OR = 1.75) to problem gambling (OR = 3.22); the steep increase in the relative risk also suggested a possible quadratic relationship between gambling level and HED risk. Notably, adjusted odds ratios showed problem gambling had the strongest association with at-least-weekly HED, followed by marijuana (OR = 3.08) and cigarette use (OR = 2.64). Gender interactions and differences were also identified and assessed. In conclusion, attention should be paid to college athletes exhibiting gambling problems, especially considering their empirical multivariate associations with high-risk drinking; accordingly, screening for problem gambling is recommended. More research is warranted to elucidate the etiologic mechanisms of these associations.

    Background The low level of response (LR) to alcohol is one of several genetically-influenced characteristics that increase the risk for heavy drinking and alcohol problems. Efforts to understand how LR operates through additional life influences have been carried out primarily in modest sized U.S.-based samples with limited statistical power, raising questions about generalizability and about the importance of components with smaller effects. This study evaluates a full LR-based model of risk in a large sample of adolescents from the U.K. Methods Cross-sectional structural equation models (SEM) were used for the approximate first half of the age 17 subjects assessed by the Avon Longitudinal Study of Parents and Children (ALSPAC), generating data on 1,905 adolescents (0 age 17.8 years, 44.2% males). LR was measured with the Self-Rating of the Effects of Alcohol (SRE) Questionnaire, outcomes were based on drinking quantities and problems, and standardized questionnaires were used to evaluate peer substance use, alcohol expectancies, and using alcohol to cope with stress. Results In this young and large U.K. sample, a low LR related to more adverse alcohol outcomes both directly and through partial mediation by all three additional key variables (peer substance use, expectancies, and coping). The models were similar in males and females. Conclusions These results confirm key elements of the hypothesized LR-based model in a large U.K. sample, supporting some generalizability beyond U.S. groups. They also indicate that with enough statistical power multiple elements contribute to how LR relates to alcohol outcomes, and reinforce the applicability of the model to both genders. PMID:21762180

    Immunotoxicity is an important health hazard of heavy metal exposure. Because the risk of combined exposure in the population cannot be neglected, we examined whether subchronic exposure to a mixture of metals (arsenic, cadmium, lead, mercury, chromium, nickel, manganese, and iron) via drinking water at contemporary Indian groundwater contamination levels and at concentrations equivalent to the WHO maximum permissible limit (MPL) in drinking water can induce immunotoxicity in male rats. Data on groundwater contamination with metals in India were collected from literature and metals were selected on the basis of their frequency of occurrence and contamination level above the MPL. Male albino Wistar rats were exposed to the mixture at 0, 1, 10, and 100 times the mode concentrations (the most frequently occurring concentration) of the individual metals in drinking water for 90 days. In addition, one group was exposed to the mixture at a concentration equal to the MPL of the individual metal and another group was used as positive control for immune response studies. The end points assessed were weights of organs, hematological indices, humoral and cell-mediated immune responses, and histopathology of skin and spleen. The MPL and 1x doses did not significantly affect any of the parameters and none of the doses induced any significant changes after 30 days of exposure. The mixture at 10x and 100x doses increased the relative weight of the spleen, but that of thymus, adrenals, and popliteal lymphnodes were increased with the 100x dose. After 90 days, 10x and 100x doses decreased serum protein and globulin contents and increased the albumin:globulin ratio; the albumin level was decreased only with the 100x dose. After 60 days, the total erythrocyte count (TEC), hemoglobin (Hb) level, and packed cell volume (PCV) were decreased with the 100x dose, whereas after 90 days, 10x and 100x doses reduced the TEC, total leukocyte count, Hb level, PCV, mean corpuscular volume, and

    Heavy drinking among individuals with HIV is associated with poor medication adherence and other health problems. Understanding reasons for drinking (drinking motives) in this population is therefore important and could inform intervention. Using concepts of drinking motives from previous alcohol research, we assessed these motives and drinking in 254 HIV-positive primary care patients (78.0% male; 94.5% African American or Hispanic) prior to their participation in an alcohol intervention trial. Three motives had good factor structure and internal consistency: “drinking to cope with negative affect”, “drinking for social facilitation” (both associated with heavier drinking), and “drinking due to social pressure” (associated with less drinking). Drinking motives may provide important content for alcohol intervention; clinical trials could indicate whether inclusion of such content improves intervention efficacy. Discussing motives in session could help providers assist clients in better managing psychological and social aspects of their lives without reliance on alcohol. PMID:24165984

  19. Role Transitions and Young Adult Maturing Out of Heavy Drinking: Evidence for Larger Effects of Marriage among More Severe Pre-Marriage Problem Drinkers

    PubMed Central

    Lee, Matthew R.; Chassin, Laurie; MacKinnon, David P.

    2015-01-01

    Background Research has shown a developmental process of “maturing out” of problem drinking beginning in young adulthood. Perhaps surprisingly, past studies suggests that young adult drinking reductions may be particularly pronounced among those exhibiting relatively severe forms of problem drinking earlier in emerging adulthood. This may occur because more severe problem drinkers experience stronger ameliorative effects of normative young adult role transitions like marriage. Methods The hypothesis of stronger marriage effects among more severe problem drinkers was tested using three waves of data from a large ongoing study of familial alcohol disorder (Chassin et al., 1992; N=844; 51% children of alcoholics). Results Longitudinal growth models characterized (1) the curvilinear trajectory of drinking quantity from ages 17-40, (2) effects of marriage on altering this age-related trajectory, and moderation of this effect by pre-marriage problem drinking levels (alcohol consequences and dependence symptoms). Results confirmed the hypothesis that protective marriage effects on drinking quantity trajectories would be stronger among more severe pre-marriage problem drinkers. Supplemental analyses showed that results were robust to alternative construct operationalizations and modeling approaches. Conclusions Consistent with role incompatibility theory, findings support the view of role conflict as a key mechanism of role-driven behavior change, as greater problem drinking likely conflicts more with demands of roles like marriage. This is also consistent with the developmental psychopathology view of transitions and turning points. Role transitions among already low-severity drinkers may merely represent developmental continuity of a low-risk trajectory, whereas role transitions among higher-severity problem drinkers may represent developmentally discontinuous “turning points” that divert individuals from a higher- to a lower-risk trajectory.

    High heavy drinking prevalence persists in students. Recently, drinking motivation received a lot of attention as an important determinant. Enhancement and coping motives are mostly positively related and conformity motives are mostly negatively related with heavy drinking. Relations are less clear for social motives. This study aimed at gaining more insight in the role of drinking motives in heavy drinking students. Overall, 15 897 Belgian university and college students (mean age: 20.7, SD = 2.6) anonymously participated in an online survey. Logistic regressions tested relationships between motives and problematic drinking (>weekly drinking, ≥monthly binge drinking and being at risk for problematic drinking by the Alcohol Use Disorders Identification Test [AUDIT]). Social motives had the highest prevalence, followed by enhancement, coping and conformity motives. Men engaged more in problematic drinking and reported more motives, except for coping. Enhancement, coping and social-motivated students have higher chances for problematic drinking, while the opposite is true for conformity-motivated students. Although this study found a similar ranking of motives as in other studies, a relationship between problematic drinking and all motives, including social motives, was revealed. This might indicate the different functions of social motives in heavy drinking in different cultures/sub-populations and countries. This finding is relevant for the development of interventions.

    College represents a period of risk for heavy drinking and experiencing unwanted consequences associated with drinking. Previous research has identified specific events including holidays (e.g., New Years), school breaks (e.g., Spring Break) and personally relevant events (e.g., 21st birthdays) that are associated with elevated risk of heavy drinking and negative alcohol-related consequences. The systematic evaluation of relative risk offers insights into event specific drinking and an empirical basis upon which to consider allocation of limited prevention resources. Thus, the purpose of the present study was to provide a comparative index of drinking across a wide range of holidays and compare holiday drinking to 21st birthday drinking. Participants were 1,124 students (55% female) who had turned 21 within the previous three weeks in 2008 and provided 90-day retrospective reports of their drinking using the Timeline Follow-back. Results based on a hurdle mixed model for blood alcohol content (BAC) revealed several holidays that stand out for elevated drinking, including New Year’s Eve and July 4th, whereas other holidays appear more similar to weekend drinking, such as Spring Break (approximately last week of March) and graduation (mid-June). Drinking on holidays or special days was substantially lower than drinking on 21st birthdays. Results are discussed in terms of practical applications for targeted intervention efforts on college campuses toward specific events where elevated drinking is known to occur. PMID:21639597

    The current study seeks to evaluate relationships between drinking motives and alcohol-related ambivalence in the prediction of problem drinking. We expected that: 1) main effects would emerge such that alcohol-related ambivalence would be positively associated with peak drinking and problems; drinking motives would be positively associated with drinking and problems, and 2) interactions would emerge between motives and ambivalence in predicting problematic drinking such that drinking motives would be positively associated with peak drinking and problems, especially among those high in ambivalence over drinking. Six hundred sixty-nine undergraduate students (mean age = 22.95, SD = 5.47, 82.22% female) completed study materials. Results showed that consistent with expectations, ambivalence was positively associated with peak drinking and problems. Further, consistent with expectations, drinking motives were positively associated with peak drinking and problems. Additionally, ambivalence was positively associated with drinking motives. Significant interactions emerged between drinking motives (social and coping) and ambivalence when predicting peak drinking and alcohol-related problems. These findings highlight the importance of considering motives in the relationship between ambivalence and drinking. Clinical implications include the need for tailoring interventions to target individual difference factors that increase risk for heavy drinking and associated problems. This is especially important among college students who may be at risk for problematic behavior. PMID:24094922

    We conducted a multicentre, retrospective, observational study including patients with solid tumours (excluding breast cancer) that received granulocyte colony-stimulating factors (G-CSF) and chemotherapy. We investigated the effectiveness of daily vs. non-daily G-CSFs (pegfilgrastim) adjusting by potential confounders. The study included 391 patients (211 daily G-CSF; 180 pegfilgrastim), from whom 47.3% received primary prophylaxis (PP) (57.8% pegfilgrastim), 26.3% secondary prophylaxis (SP: initiation after cycle 1 and no reactive treatment in any cycle) (51.5% pegfilgrastim) and 26.3% reactive treatment (19.4% pegfilgrastim). Only 42.2% of patients with daily G-CSF and 46.2% with pegfilgrastim initiated prophylaxis within 72 h after chemotherapy, and only 10.5% of patients with daily G-CSF received it for ≥7 days. In the multivariate models, daily G-CSF was associated with higher risk of grade 3-4 neutropenia (G3-4N) vs. pegfilgrastim [odds ratio (OR): 1.73, 95% confidence interval (CI): 1.004–2.97]. Relative to SP, PP protected against G3-4N (OR for SP vs. PP: 6.0, 95%CI: 3.2–11.4) and febrile neutropenia (OR: 3.1, 95%CI: 1.1–8.8), and was associated to less chemotherapy dose delays and reductions (OR for relative dose intensity <85% for SP vs. PP: 3.1, 95%CI: 1.7–5.4) and higher response rate (OR: 2.1, 95%CI: 1.2–3.7). Data suggest that pegfilgrastim, compared with a daily G-CSF, and PP, compared with SP, could be more effective in preventing neutropenia and its related events in the clinical practice.

    Aims Bupropion was tested for efficacy to achieve methamphetamine (MA) abstinence in dependent, non-daily users. Methods A randomized, double-blind, placebo-controlled trial, with 12-week treatment and 4-week follow-up, was conducted with 204 treatment-seeking participants having MA dependence per DSM-IV, who used MA on a less-than-daily basis. 104 were randomized to matched placebo and 100 to bupropion, sustained-release 150mg, twice daily. Participants were seen three times weekly to obtain urine for MA and bupropion assays, study assessments, and thrice weekly, 90-minute, group psychotherapy. There was no biomarker for placebo adherence. The primary outcome was achievement of abstinence throughout the last two weeks of treatment; ‘success’ requiring at least two urine samples during each of Weeks 11 and 12, and all samples MA-negative (<300ng/mL). Results Bupropion and placebo groups did not differ significantly in the percentage achieving abstinence for the last 2 weeks of treatment (chi-square, p=0.32). Subgroup analysis of participants with lower baseline MA use (≤18 of last 30 days before consent) also revealed no difference in success between groups (p=0.73). Medication adherence per protocol (detectable bupropion, >5ng/mL, in ≥50% of urine samples from Study Weeks 1–10 and ≥66% of urine samples from Weeks 11–12) was achieved by 47% of participants taking bupropion. Conclusions These data indicate that bupropion did not increase abstinence in dependent participants who were using MA less-than-daily. Medication non-adherence was a limitation in this trial. Psychosocial therapy remains the mainstay of treatment for MA dependence. Further research on subgroups who may respond to bupropion may be warranted.

    Objective: The market and degree of consumption of energy drinks have exponentially expanded while studies that assess their psychological effects and impact on quality of life remain in the early stages, albeit on the rise. This review aims to examine the literature for evidence of the psychological effects of energy drinks and their impact on the sense of well-being and quality of life. Methods: Studies were identified through Pubmed, Medline, and PsycINFO searches from the dates of 1990 to 2011, published in English, using the keywords energy or tonic drinks, psychological effects, caffeine and cognitive functions, mood, sleep, quality of life, well-being, and mental illness. Three authors agreed independently on including 41 studies that met specific selection criteria. Results: The literature reveals that people most commonly consume energy drinks to promote wakefulness, to increase energy, and to enhance the experience of alcohol intoxication. A number of studies reveal that individuals who consume energy drinks with alcohol were more inclined to be involved in risk-taking behaviors. There was also excessive daytime sleepiness the day following energy drink consumption. Contrary to expectations, the impact of energy drinks on quality of life and well-being was equivocal. Conclusions: Energy drinks have mixed psychological and well-being effects. There is a need to investigate the different contexts in which energy drinks are consumed and the impact on mental health, especially in the psychiatrically ill. PMID:22347688

    The objective was to determine whether discrepancies between husbands’ and wives’ past year heavy drinking predicted decreased marital satisfaction over time. Participants were recruited at the time they applied for their marriage licenses (N= 634). Couples completed questionnaires about their alcohol use and marital satisfaction at the time of marriage, and again at their first and second anniversaries. Generalized estimating equation models were used to evaluate the association between discrepancies in husbands’ and wives’ heavy drinking in the year prior to marriage and marital satisfaction at the first wedding anniversary and the association between discrepancies in heavy alcohol use in the first year of marriage and marital satisfaction at the second wedding anniversary. In these prospective time-lagged analyses, discrepancies in husbands’ and wives’ heavy drinking predicted decreased marital satisfaction over time while controlling for heavy drinking. Over time, these couples may be at greater risk for decreased marital functioning that may lead to relationship dissolution. PMID:17295562

    We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections with urbanization, and their potential risk posed on the ecosystem. Determination of metal concentrations in 50 topsoil samples and nine soil profiles indicated that Hg, Pb, Zn, and Cu were present in significantly higher concentrations in topsoil than in deep soil layers. The spatial distributions of Hg, Pb, Zn, and Cu and contamination hotspots for these metals in the study area were similar to those near heavy industries and urban built-up areas. Emissions from automobiles resulted in increased soil concentrations of Cu, Pb, and Zn along roadsides, while high concentrations of Hg in the soil resulted from recent atmospheric deposition. Calculation of the potential ecological risk indicated that the integrative risk of these heavy metals in most areas was low, but a few sites surrounding high density of factories showed moderate risks.

    As it is still unclear to what extent parental drinking is a predictor of children's alcohol use, we tested the association of specific paternal and maternal drinking patterns with both initiation and development of adolescent alcohol use. Longitudinal data (four annual measurements) of parent-child dyads (N=2319) have been used. Parental drinking patterns have been identified using latent class analysis. The association of parental drinking patterns with the initiation and development of 12-15 year olds' drinking have been examined with latent growth curve modeling. Only two out of six parental drinking patterns were related to adolescent drinking. That is, having a heavy drinking father or two heavy episodic drinking parents particularly predicts early and heavier adolescent drinking. When controlled for parenting behaviors and background variables, such as adolescent gender, age and socioeconomic status (SES), these findings remained significant. Interaction analyses revealed that the influence of parental heavy (episodic) drinking differs across gender and is especially strong among adolescents with lower SES. Thus, parental heavy (episodic) drinking, and not so much the frequency of drinking, predicts the initiation and development of alcohol consumption in their offspring. Parents and professionals must be aware that parental heavy drinking affects their offspring, particularly adolescents with lower SES, resulting in earlier and heavier drinking among this high-risk group.

    As part of a multicenter project supported by the World Health Organization, we developed a web-based intervention to reduce alcohol use and related problems. We evaluated the predictors of adherence to, and the outcomes of the intervention. Success was defined as a reduction in consumption to low risk levels or to <50% of the baseline levels of number of drinks. From the 32,401 people who accessed the site, 3389 registered and 929 completed the full Alcohol Use Disorders Identification Test (AUDIT), a necessary condition to be considered eligible to take part in the intervention. Based on their AUDIT scores, these participants were classified into: low risk users (LRU; n=319) harmful/hazardous users (HHU; n=298) or suggestive of dependence users (SDU; n=312). 29.1% of the registered users (LRU=42; HHU=90; SDU=82) completed the evaluation form at the end of the six-week period, and 63.5% reported low-risk drinking levels. We observed a significant reduction in alcohol consumption in the HHU (62.5%) and SDU (64.5%) groups in relation to baseline. One month after the intervention, in the follow-up, 94 users filled out the evaluation form, and their rate of success was similar to the one observed in the previous evaluation. Logistic regression analyses indicated that HHU participants presented higher adherence than LRU. Despite a relatively low adherence to the program, its good outcomes and low cost, as well as the high number of people that can be reached by a web-based intervention, suggest it has good cost-effectiveness.

    Alcohol attitudes are often considered an important predecessor of drinking behavior, although the literature is equivocal. Lately, attention has turned to enhancing positive cognitions on alcoholic-free drinks to discourage heavy drinking. The current study was the first to longitudinally examine associations between attitudes towards binge drinking and alcohol-free drinks and binge drinking behavior in a cross-lagged path model in Mplus. Participants were 293 adolescents (131 boys, M(age)=16.1 years) who filled in two online questionnaires with a six-month interval. Binge drinking behavior and attitudes towards binge drinking and alcohol-free drinks were all significantly correlated at both waves. The multivariate model, however, showed that only higher levels of binge drinking at T1 were prospectively related to more positive binge drinking attitudes at T2, and not vice versa. Analyses were controlled for sex, educational level, and age. Findings discard the Theory of Planned Behavior, but rather seem consistent with the Theory of Cognitive Dissonance, i.e., adolescents may adapt their cognitions to their behavior. More longitudinal research with several time points and over a longer period of time is needed to further examine the development of attitudes and drinking behavior. PMID:23435271

    Increasing water pollution in developing countries poses a significant threat to environmental health and human welfare. Understanding the spatial distribution and apportioning the sources of pollution are important for the efficient management of water resources. In this study, ten types of heavy metals were detected during 2010-2013 for all ambient samples and point sources samples. A pollution assessment based on the surficial sediment dataset by Enrichment Factor (EF) showed the surficial sediment was moderately contaminated. A comparison of the multivariate approach (principle components analysis/absolute principle component score, PCA/APCS) and the chemical mass balance model (CMB) shows that the identification of sources and calculation of source contribution based on the CMB were more objective and acceptable when source profiles were known and source composition was complex. The results of source apportionment for surficial heavy metals, both from PCA/APCS and CMB model, showed that the natural background (30%) was the most dominant contributor to the surficial heavy metals, followed by mining activities (29%). The contribution percentage of the natural background was negatively related to the degree of contamination. The peak concentrations of many heavy metals (Cu, Ba, Fe, As and Hg) were found in the middle layer of sediment, which is most likely due to the result of development of industry beginning in the 1970s. However, the highest concentration of Pb appeared in the surficial sediment layer, which was most likely due to the sharp increase in the traffic volume. The historical analysis of the sources based on the CMB showed that mining and the chemical industry are stable sources for all of the sections. The comparing of change rates of source contribution versus years indicated that the composition of the materials in estuary site (HF1) is sensitive to the input from the land, whereas center site (HF4) has a buffering effect on the materials from

    Exposure to alcohol in utero can cause birth defects, including face and brain abnormalities, and is the most common preventable cause of intellectual disabilities. Here we use structural magnetic resonance imaging to measure cortical volume change longitudinally in a cohort of human children and youth with prenatal alcohol exposure (PAE) and a group of unexposed control subjects, demonstrating that the normal processes of brain maturation are disrupted in individuals whose mothers drank heavily during pregnancy. Trajectories of cortical volume change within children and youth with PAE differed from those of unexposed control subjects in posterior brain regions, particularly in the parietal cortex. In these areas, control children appear to show a particularly plastic cortex with a prolonged pattern of cortical volume increases followed by equally vigorous volume loss during adolescence, while the alcohol-exposed participants showed primarily volume loss, demonstrating decreased plasticity. Furthermore, smaller volume changes between scans were associated with lower intelligence and worse facial morphology in both groups, and were related to the amount of PAE during each trimester of pregnancy in the exposed group. This demonstrates that measures of IQ and facial dysmorphology predict, to some degree, the structural brain development that occurs in subsequent years. These results are encouraging in that interventions aimed at altering "experience" over time may improve brain trajectories in individuals with heavy PAE and possibly other neurodevelopmental disorders.

    Alcohol is the substance most frequently abused by children and adolescents in the United States, and its use is associated with the leading causes of death and serious injury at this age (ie, motor vehicle accidents, homicides, and suicides). Among youth who drink, the proportion who drink heavily is higher than among adult drinkers, increasing from approximately 50% in those 12 to 14 years of age to 72% among those 18 to 20 years of age. In this clinical report, the definition, epidemiology, and risk factors for binge drinking; the neurobiology of intoxication, blackouts, and hangovers; genetic considerations;and adverse outcomes are discussed. The report offers guidance for the pediatrician. As with any high-risk behavior, prevention plays a more important role than later intervention and has been shown to be more effective. In the pediatric office setting, it is important to ask every adolescent about alcohol use. PMID:26324872

    An investigation of arsenic, copper, nickel, manganese, zinc and selenium concentration in foodstuffs and drinking water, collected from 34 families and estimation of the average daily dietary intake were carried out in the arsenic-affected areas of the Jalangi and Domkal blocks, Murshidabad district, West Bengal where arsenic-contaminated groundwater (mean: 0.11 mg/l, n=34) is the main source for drinking. The shallow large diameter tubewells, installed for agricultural irrigation contain an appreciable amount of arsenic (mean: 0.094 mg/l, n=10).

    An investigation of arsenic, copper, nickel, manganese, zinc and selenium concentration in foodstuffs and drinking water, collected from 34 families and estimation of the average daily dietary intake were carried out in the arsenic-affected areas of the Jalangi and Domkal blocks, Murshidabad district, West Bengal where arsenic-contaminated groundwater (mean: 0.11 mg/l, n=34) is the main source for drinking. The shallow large diameter tubewells, installed for agricultural irrigation contain an appreciable amount of arsenic (mean: 0.094 mg/l, n=10).

    This study set out to investigate the pressures experienced by different individuals to drink, or drink a little more than intended, by someone who drinks or drinks more than they do. A total of 2099 Nigerian adults between the ages of 18 and 65 years were randomly sampled. The frequency with which they experienced such other drinkers encouraging them to drink or drink more than intended from various sources was examined. Logistic regression was used to identify significant individual predictors of receiving pressure by sources of influence. Focus group discussions were also held to examine how these pressures are applied in various settings. Results indicated that male friends or acquaintances were the sources respondents reported influenced them the most to drink or drink more. Significant predictors of pressure varied by source but tended to include religion (5 of 6 sources) and gender (3 of 6). Results showed that pressure to drink or drink a little more was seen to come more from males than from females. It raises the need to have a better knowledge of these factors, particularly as they may relate to heavy or problematic drinking, and their implications for prevention and treatment. PMID:20651928

    The present study examined the effectiveness of expressive writing in reducing drinking behavior. We expected that students prompted to write about negative drinking experiences would show greater decreases in future drinking intentions compared to the neutral and the positive writing conditions. We also expected that decreases in drinking intentions following the writing prompts might differ based on current drinking and AUDIT scores. Participants included 200 (76% female) undergraduates who completed measures of their current drinking behavior. They were then randomly assigned to either write about: a time when they had a lot to drink that was a good time (Positive); a time when they had a lot to drink that was a bad time (Negative); or their first day of college (Neutral), followed by measures assessing intended drinking over the next three months. Results revealed that participants intended to drink significantly fewer drinks per week and engage in marginally fewer heavy drinking occasions after writing about a negative drinking occasion when compared to control. Interactions provided mixed findings suggesting that writing about a positive event was associated with higher drinking intentions for heavier drinkers. Writing about a negative event was associated with higher intentions among heavier drinkers, but lower intentions among those with higher AUDIT scores. This research builds on previous expressive writing interventions by applying this technique to undergraduate drinkers. Preliminary results provide some support for this innovative strategy but also suggest the need for further refinement, especially with heavier drinkers.

    The current investigation sought to examine “day of the week” drinking of an at-risk sample of nonstudent emerging adults and whether specific factors are associated with differential drinking patterns. Our study aims were to: (1) identify differences in weekday versus weekend drinking, (2) examine specific expectancies (i.e., sociability, tension reduction) and demographic factors (e.g., age, sex) as relating to weekend versus weekday drinking after controlling for harmful drinking and holiday drinking. Participants were 238 (63.4% men, 35.7% women; M age = 21.92 years) heavy drinking noncollege-attenders recruited from the community. They reported daily drinking for the previous 30 days and completed measures of harmful drinking, alcohol expectancies, and demographic information. Results showed that more drinks were consumed on the weekends (i.e., Thursday to Saturday) than weekdays, with 63% of drinks consumed on weekends. Multilevel modeling analyses indicated that weekday drinking was associated with tension reduction expectancies, social expectancies, sex, and age. Weekend drinking increases were related to social expectancies but not tension reduction expectancies. Our final model indicated that, after controlling for the effect of holiday drinking, the within-person weekday/weekend distinction explained 18% of the total variance. In general, our findings highlight the importance of alcohol expectancies and drinking contexts in understanding the drinking behaviors of nonstudents. The differential role of tension reduction and social facilitation expectancies on drinking throughout the week imply different cognitive pathways are involved in weekday versus weekend drinking and both types of expected alcohol effects should be targets of risk-reduction efforts with nonstudent drinkers.

    Aims U.S. college drinking data and a simple population model of alcohol consumption are used to explore the impact of social and contextual parameters on the distribution of light, moderate, and heavy drinkers. Light drinkers become moderate under social influence, moderate drinkers may change environments and become heavy drinkers. We estimate the drinking reproduction number, Rd, the average number of individual transitions from light to moderate drinking that result from the introduction of a moderate drinker in a population of light drinkers. Methods Ways of assessing and ranking progression of drinking risks and data-driven definitions of high- and low-risk drinking environments are introduced. Uncertainty and sensitivity analyses, via a novel statistical approach, are conducted to assess Rd variability and to analyze the role of context on drinking dynamics. Results Our estimates show Rd well above the critical value of 1. Rd estimates correlate positively with the proportion of time spent by moderate drinkers in high-risk drinking environments. Rd is most sensitive to variations in local social mixing contact rates within low-risk environments. The parameterized model with college data, suggests that high residence times of moderate drinkers in low-risk environments maintain heavy drinking. Conclusions With regard to alcohol consumption in US college students, drinking places, the connectivity (traffic) between drinking venues, and the strength of socialization in local environments are important determinants in transitions between light, moderate and heavy drinking as well as in long-term prediction of the drinking dynamics.

    Objectives The time of drinking in terms of daytime versus evening and weekday versus weekend is charted for regular drinkers in 14 countries in Europe, Asia, Latin America, Africa and Oceania. Methods national or regional adult population surveys from the GENACIS project. Results: The weekly rhythm of drinking varies greatly between societies. Drinking was generally more likely after 5 pm and on weekends. To this extent, alcohol consumption is now regulated by a universal clock. The relation of time of day and of the week of drinking to problems from drinking varied between societies. Drinking at specific times was more likely to predict problems among men than women, though for men the particular time varied, while weekday evenings were the most problematic time for women. The relation of drinking at a particular time to problems in part reflected that heavy drinkers were more likely to be drinking at that time. Conclusions There are commonalities across cultures in drinking by time of day and day of the week, but the implications of the timing for alcohol-related problems are fairly culture-specific.

    2011-01-01

    Introduction and Aims For consumers to follow drinking guidelines and limit their risk of negative consequences they need to track their ethanol consumption. This paper reviews published research on the ability of consumers to utilise information about the alcohol content of beverages when expressed in different forms e.g. in standard drinks or units versus percentage alcohol content.. Design and Methods A review of the literature on standard drink definitions and consumer understanding of these, actual drink pouring, use of standard drinks in guidelines and consumer understanding and use of these. Results Standard drink definitions vary across countries and typically contain less alcohol than actual drinks. Drinkers have difficulty defining and pouring standard drinks with over-pouring being the norm such that intake volume is typically underestimated. Drinkers have difficulty using percentage alcohol by volume and pour size information in calculating intake but can effectively utilise standard drink labeling to track intake. Discussion and Conclusions Standard drink labeling is an effective but little used strategy for enabling drinkers to track their alcohol intake and potentially conform to safe or low risk drinking guidelines.

  1. GRIK1 Genotype Moderates Topiramate's Effects on Daily Drinking Level, Expectations of Alcohol's Positive Effects, and Desire to Drink

    We (Kranzler et al. 2014) reported that topiramate 200 mg/day reduced heavy drinking days and increased abstinent days in 138 heavy drinkers whose treatment goal was to reduce drinking to safe levels. In that 12-week, placebo-controlled study, we measured drinking using the Timeline Follow-back method at each treatment visit. In addition to the intent-to-treat effects of topiramate, we found that a single nucleotide polymorphism (rs2832407) in GRIK1, encoding the GluK1 subunit of the kainate receptor, moderated the treatment effect in European Americans (EAs; n=122). Topiramate reduced heavy drinking only in rs2832407*C allele homozygotes. Here, we augment those analyses by using patients’ daily reports obtained using interactive voice response technology (a) to validate the interactive effects of GRIK1 and topiramate as predictors of drinking level and (b) to examine changes in expected positive effects of drinking (i.e., positive outcome expectancies) and desire to drink. We found that rs2832407*C allele homozygotes treated with topiramate drank less overall during treatment than those receiving placebo, validating our earlier findings for heavy drinking days (Kranzler et al. 2014). There was also a study day × medication group × genotype group interaction that predicted both positive alcohol expectancies and desire to drink, with rs2832407*C-allele homozygotes treated with topiramate showing the largest decreases in these outcomes during the study period. Changes in positive alcohol expectancies or desire to drink did not mediate the effects on drinking. These findings validate and extend our previous pharmacogenetic findings with topiramate.

    2015-01-01

    Background Binge drinking (≥4 drinks for women; ≥5 drinks for men, per occasion) is responsible for more than half of the estimated 80,000 U.S. deaths annually and three-quarters of the $223.5 billion in costs in 2006. Binge drinking prevalence is assessed more commonly than binge drinking intensity (i.e., number of drinks consumed per binge episode). Risk of binge drinking–related harm increases with intensity, and thus it is important to monitor. The largest number of drinks consumed is assessed in health surveys, but its usefulness for assessing binge intensity is unknown. Purpose To assess the agreement between two potential measures of binge drinking intensity: the largest number of drinks consumed by binge drinkers (maximum-drinks) and the total number of drinks consumed during their most recent binge episode (drinks-per-binge). Methods Data were analyzed from 7909 adult binge drinkers from 14 states responding to the 2008 Behavioral Risk Factor Surveillance System (BRFSS) binge drinking module. Mean and median drinks-per-binge from that module were compared to mean and median maximum-drinks. Analyses were conducted in 2010–2011. Results Mean (8.2) and median (5.9) maximum-drinks were strongly correlated with mean (7.4) and median (5.4) drinks-per-binge (r=0.57). These measures were also strongly correlated across most sociodemographic and drinking categories overall and within states. Conclusions The maximum-drinks consumed by binge drinkers is a practical method for assessing binge drinking intensity and thus can be used to plan and evaluate Community Guide–recommended strategies for preventing binge drinking (e.g., increasing the price of alcoholic beverages and regulating alcohol outlet density).

    This study used data on 42,862 U.S. adults, including 18,352 past-year drinkers, to describe differentials by race and national origin in U.S. drinking patterns. Age-sex standardized estimates were presented within 21 categories of ethnic origin for whites and within five categories each for individuals of black and other races. Of the three racial groups, whites were the most likely to drink, but blacks had the highest volume of intake and frequency of heavy drinking. Differences by ethnic origin within racial categories were as marked as differentials between races. Compared to whites of European origin, those of Hispanic and native American origin were less likely to drink but consumed more alcohol on days when they drank. Whites of Southern and Eastern European origin drank proportionately more wine and demonstrated more moderate drinking patterns (lower intake per drinking day and/or less frequent heavy drinking) than those of Northern or Central European origin. Hispanics of Caribbean origin were less prone to heavy drinking than other white Hispanics; similarly, blacks from the English-speaking Caribbean showed more moderate drinking patterns than other blacks. Individuals of Asian origin, in particular those of non-Japanese origin, had the most moderate drinking patterns within the category of other race. Although the black/white differentials in volume of intake and frequency of heavy drinking disappeared after adjusting for marital status, education and income, most of the differences by ethnic origin retained their statistical significance if not their original magnitudes. These findings indicate that cultural forces exert a strong effect on drinking behavior. Differences among European whites with respect to prevalence of drinking, beverage preference and frequency of heavy drinking suggest that the association between ethnic origin and drinking behavior may persist even after many generations of presumed acculturation.

  4. Drinking histories of fatally injured drivers

    PubMed Central

    Baker, S; Braver, E; Chen, L; Li, G; Williams, A

    2002-01-01

    Context: About 30% of drivers killed in crashes have high blood alcohol concentrations (BACs) of 0.10+ g/dl. There is a question about whether these drivers primarily are problem drinkers who chronically drink and drive—the so-called hard core drinking drivers. Objective: To investigate drinking histories of fatally injured drivers in relation to their BACs. Design and participants: Retrospective cohort study of 818 fatally injured drivers who were included in the 1993 National Mortality Followback Survey (a national sample of US deaths in which next of kin were interviewed) and whose BACs were recorded by the Fatality Analysis Reporting System, a census of US traffic deaths. Main outcome measure: Problem drinking indicators. Results: At least one indicator of potential problem drinking, primarily heavy drinking, was reported for 68% of drivers with very high BACs (0.15+ g/dl), 41% with BACs of 0.10–0.14 g/dl, 32% with BACs of 0.01–0.09 g/dl, and 7% with zero BACs. Spouses provided more credible responses than other relatives: they were more likely to report at least occasional drinking and driving among deceased drivers with high BACs. For the most direct signs of problem drinking (described as a problem drinker during the last month of life or frequently driving after having five or more drinks), spousal reports suggested the prevalence of problem drinking among drivers with very high BACs was 22% (having both indicators), 32% (frequently driving after having five or more drinks), 44% (described as problem drinker), or 57% (having either indicator). Conclusions: Drivers with BACs of 0.10+ g/dl were far more likely than sober drivers to be described as having markers of problem drinking. However, many did not have indicators suggestive of problem drinking. In addition to programs focused on repeat offenders or problem drinkers, countermeasures such as sobriety checkpoints that target a broader spectrum of drinking drivers are appropriate.

    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. PMID:7604923

    Many efforts to prevent alcohol-related harm are aimed at reducing risk drinking. This article outlines the many conceptual and methodological challenges to defining risk drinking. It summarizes recent evidence regarding associations of various aspects of alcohol consumption with chronic and acute alcohol-related harms, including mortality, morbidity, injury, and alcohol use disorders, and summarizes the study designs most appropriate to defining risk thresholds for these types of harm. In addition, it presents an international overview of low-risk drinking guidelines from more than 20 countries, illustrating the wide range of interpretations of the scientific evidence related to risk drinking. This article also explores the impact of drink size on defining risk drinking and describes variation in what is considered to be a standard drink across populations. Actual and standard drink sizes differ in the United States, and this discrepancy affects definitions of risk drinking and prevention efforts. PMID:22330212

    Alcohol consumption and drinking habits among Finnish doctors were studied as part of a survey of stress and burnout. A questionnaire containing 99 questions or groups of questions was sent to all 3496 practising doctors aged under 66 randomly selected from the registry of the Finnish Medical Association. Altogether 2671 doctors (76%) responded; this sample was representative of the Finnish medical profession. The average weekly consumption of alcohol during the past year and various aspects of drinking behaviour were assessed, and the presence or absence of symptoms and diseases often encountered among heavy drinkers and addicts was determined. The data were analysed separately for men and women, for those aged less than or equal to 40 and greater than 40, and for the men with high and low alcohol consumption and with high and low scores on the index of drinking habits. Selected variables related to work, stress, and coping were correlated with alcohol consumption and drinking behaviour. The median consumption of alcohol among male doctors was 4876 g (6.2 litres) and among female doctors 2226 g (2.8 litres) of absolute alcohol per person per year and was higher in those aged over 40. Beer was most commonly drunk by men and wine by women. Increased alcohol consumption was associated with older age, disappointment with career, heavy smoking, use of benzodiazepines, stress and burnout symptoms, suicidal thoughts, general dissatisfaction, and diseases related to alcohol. Drinking habits were heavier among doctors working in community health centres, those taking long sick leaves, younger doctors disappointed with their careers or the atmosphere at work, and older doctors immersed in their work. Alcohol consumption among doctors seems to be higher than that of the general population in Finland, and heavy drinking seems to be associated with stress and burnout. PMID:3142564

    BACKGROUND Heavy drinking among individuals with HIV is associated with major health concerns (liver disease, medication nonadherence, immune functioning), but little is known about cognitive-motivational factors involved in alcohol consumption in this population, particularly reasons for limiting drinking. METHODS Urban HIV primary care patients (N=254; 78.0% male; 94.5% African American or Hispanic) in a randomized trial of brief drinking-reduction interventions reported on reasons for limiting drinking, alcohol consumption, and alcohol dependence symptoms prior to intervention. RESULTS Exploratory factor analysis indicated three main domains of reasons for limiting drinking: social reasons (e.g., responsibility to family), lifestyle reasons (e.g., religious/moral reasons), and impairment concerns (e.g., hangovers). These factors evidenced good internal consistency (αs=0.76–0.86). Higher scores on social reasons for limiting drinking were associated with lower typical quantity, maximum quantity, and binge frequency (ps<0.01), and higher scores on lifestyle reasons were associated with lower maximum quantity, binge frequency, and intoxication frequency (ps<0.01). In contrast, higher scores on impairment concerns were associated with more frequent drinking and intoxication, and higher risk of alcohol dependence (ps<0.05), likely because dependent drinkers are more familiar with alcohol-induced impairment. CONCLUSIONS The current study is the first to explore reasons for limiting drinking among individuals with HIV, and how these reasons relate to alcohol involvement. This study yields a scale that can be used to assess reasons for limiting drinking among HIV-positive drinkers, and provides information that can be used to enhance interventions with this population. Discussing social and lifestyle reasons for limiting drinking among less extreme drinkers may support and validate these patients’ efforts to limit engagement in heavy drinking; discussion of

    Research supports a bidirectional association between heavy alcohol use and marital quality among couples. The current research extends previous research on the role of interpersonal perception by examining how partner drinking and perceiving one's partner's drinking as problematic are associated with subsequent marital outcomes. Specifically, we evaluated how perceiving one's partner to have a drinking problem was associated with marital functioning, and whether that association differed based on the partner's actual drinking. Married couples (N = 123 dyads) with at least one spouse who consumed alcohol regularly completed measures of alcohol use and consequences, the perception that their spouse's drinking was problematic, and marital adjustment (i.e., relationship satisfaction, commitment, and trust). Results from actor-partner interdependence models using structural equations modeling indicated that for husbands, partner heavy drinking was associated with lower adjustment. Additionally, for husbands, perceiving their spouse had a drinking problem was associated with lower adjustment for both themselves and their wives. Moreover, significant interactions between partner drinking and the perception of partner drinking problem on marital adjustment emerged. Specifically, perceiving one's partner's drinking as a problem was only negatively associated with relationship adjustment if the partner reported higher levels of heavy drinking. This pattern was stronger for husbands. Results illustrate the importance of interpersonal perception, gender differences, and the use of dyadic data to model the complex dynamic between spouses with regard to alcohol use and how it affects relationship outcomes.

  13. Haemorrhagic diarrhoea and reproductive failure in Bonsmara cattle resulting from anomalous heavy metal concentrations in soils, forages and drinking water associated with geochemical anomalies of toxic elements on the farm Puntlyf, South Africa

    Poor livestock health conditions are associated with geochemical Pb anomalies on a farm approximately 40km east of Pretoria, South Africa. A generic risk assessment of drinking water for Bonsmara cattle obtained from three separate subterranean water sources on the farm, revealed the presence of several potentially hazardous constituents suspected for the development of adverse health effects in the herd. The two main symptoms of the herd, namely, severe haemorrhagic diarrhoea in calves and reproductive failure in cows, have been investigated. A selenium-induced copper deficiency was proposed as the main cause to the calf diarrhoea, due to complexing between high concentrations of Se, Mo, Hg and Pb in drinking water. It was also anticipated that such Cu deficiencies would lead to low systemic Se inducing hypothyroidism in the cows due to inadequate iodine activation required for thyroid hormone formation and consequently adversely affect reproduction. The anomalous Pb in borehole drinking water on the southem part of the farm, suggests a clear genetic link with the underlying geochemical Pb anomalies detected by means of an ongoing regional geochemical survey.

    Many college students drink heavily and experience myriad associated negative consequences. This review suggests that a developmental perspective can facilitate a better understanding of college drinking. Specifically, using an emerging adulthood framework that considers the ongoing role of parents and neurodevelopmental processes can provide insight into why students drink. Most college students drink and tend to drink more and more heavily than their non–college-attending peers. These drinking patterns are affected by environmental and temporal characteristics specific to the college environment, including residential campus living, the academic week, and the academic year. Additional psychosocial factors are of particular relevance to the drinking behavior of college-age people, and include exaggerated peer norms, the development and use of protective behavioral strategies, and mental health considerations. Understanding the unique interaction of person and environment is key to designing prevention/intervention efforts. PMID:27159817

    Researchers have found that, compared to European Americans, African Americans report later initiation of drinking, lower rates of use, and lower levels of use across almost all age groups. Nevertheless, African Americans also have higher levels of alcohol problems than European Americans. After reviewing current data regarding these trends, we provide a theory to understand this apparent paradox as well as to understand variability in risk among African Americans. Certain factors appear to operate as both protective factors against heavy use and risk factors for negative consequences from use. For example, African American culture is characterized by norms against heavy alcohol use or intoxication, which protects against heavy use but also provides within-group social disapproval when use does occur. African Americans are more likely to encounter legal problems from drinking than European Americans, even at the same levels of consumption, perhaps thus resulting in reduced consumption but more problems from consumption. There appears to be one particular group of African Americans, low-income African American men, who are at the highest risk for alcoholism and related problems. We theorize that this effect is due to the complex interaction of residential discrimination, racism, age of drinking, and lack of available standard life reinforcers (e.g., stable employment and financial stability). Further empirical research will be needed to test our theories and otherwise move this important field forward. A focus on within-group variation in drinking patterns and problems is necessary. We suggest several new avenues of inquiry. PMID:23477449

    Alcohol drinking habits and alcoholism are partly genetically determined. Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence interval (CI): 9.1-11) among men with the ADH1B.1/1 genotype compared to 7.5 drinks (95% CI: 6.4-8.7) among men with the ADH1B.1/2 genotype, and the odds ratio (OR) for heavy drinking was 3.1 (95% CI: 1.7-5.7) among men with the ADH1B.1/1 genotype compared to men with the ADH1B.1/2 genotype. Furthermore, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1/1 genotype. Results for ADH1B and ADH1C genotypes among men and women were similar. Finally, because slow ADH1B alcohol degradation is found in more than 90% of the white population compared to less than 10% of East Asians, the population attributable risk of heavy drinking and alcoholism by ADH1B.1/1 genotype was 67 and 62% among the white population compared with 9 and 24% among the East Asian population.

    This study explored narratives of drinking as a coping strategy among female drinkers in a South African township. In 2010–11, we conducted qualitative in-depth interviews with 54 women recruited from 12 alcohol-serving venues. Most women drank heavily and linked their drinking to stressors. They were motivated to use drinking to manage their emotions, facilitate social engagement, and achieve a sense of empowerment, even while recognizing the limitations of this strategy. This study helps to contextualize heavy drinking behavior among women in this setting. Multifaceted interventions that help female drinkers to more effectively manage stressors may aid in reducing hazardous drinking. PMID:23905586

    2015-01-01

    Students with trauma and posttraumatic stress are disproportionately at risk for heavy drinking and for alcohol-related consequences. Brief motivational interventions (BMIs) have been shown to reduce hazardous drinking in college students, and could serve as a first-line approach to reduce heavy drinking in students with trauma and posttraumatic stress (PTS). Yet the standard BMI format may not adequately address the factors that lead to hazardous drinking in these students. Here, we review the literature on PTS and hazardous drinking in college students, and highlight cognitive (self-efficacy, alcohol expectancies) and behavioral (coping strategies, emotion regulation skills, protective behaviors) factors that may link trauma and PTS to drinking risk. Incorporating these factors into standard BMIs in a collaborative way that enhances their personal relevance may enhance intervention efficacy and acceptability for these at-risk students.

    Background Despite tremendous growth in research examining the role of cognitive bias in addictive behaviors, scant consideration has been paid to the close association between smoking and drinking behavior. This study sought to determine whether an association between smoking and drinking could be observed at an implicit level using a novel cognitive bias task, as well as characterize the relationship between performance on this task and clinically relevant variables (i.e., heaviness of use/dependence). Methods Individuals (N = 51) with a range of smoking and drinking patterns completed a modified Stroop task in which participants identified the color of drinking, smoking and neutral words that were each preceded by drinking, smoking or neutral picture primes. Participants also provided information regarding the heaviness of their smoking and drinking behavior and completed self-report measures of alcohol and nicotine dependence. Results Response times to smoking and drinking words were significantly slowed following the presentation of either smoking or drinking picture primes. This effect did not differ across subgroups. However, the strength of the coupling between smoking and drinking prime effects was greater among heavier drinkers, who also exhibited a concordant looser coupling of the effects of smoking and drinking primes on smoking words. Conclusions Associations between smoking and drinking can be observed at an implicit level and may be strongest for heavier drinkers. PMID:25561386

    BACKGROUND For individuals with HIV, heavy drinking can pose serious threats to health. Some interventions are effective at reducing drinking in this population, but many HIV-infected heavy drinkers also use marijuana or cocaine. Although these drugs have predicted poor alcohol outcomes in other treatment studies, whether this occurs among HIV patients who drink heavily is unknown. METHODS Participants were binge-drinking HIV primary care patients (N=254) enrolled in a randomized trial of three brief drinking interventions over 60 days that varied in intensity. We investigated the relationship of baseline past-year drug use (marijuana-only, cocaine-only, both, neither) to end-of-treatment drinking quantity and frequency. We also evaluated whether the relationship between intervention type and end-of-treatment drinking varied by baseline drug use. Final models incorporated control for patients’ demographic and HIV characteristics. RESULTS In final models, drinking frequency at the end of treatment did not vary by baseline drug use, but drinking quantity did (X2 [3] = 13.87, p<0.01), with individuals using cocaine-only drinking significantly more per occasion (B=0.32, p<0.01). Baseline drug use also interacted with intervention condition in predicting end-of-treatment drinking quantity (X2 [6] = 13.98, p<0.05), but not frequency, with the largest discrepancies in end-of-treatment drinks per drinking day by intervention intensity among cocaine-only patients. CONCLUSIONS In general, HIV patients using cocaine evidenced the highest levels of drinking after alcohol intervention. However, these individuals also evidenced the most pronounced differences in end-of-treatment drinking by intervention intensity. These results suggest the importance of more intensive intervention for individuals using alcohol and cocaine. PMID:25920801

    Accounts of drinking water-borne disease outbreaks have always captured the interest of the public, elected and health officials, and the media. During the twentieth century, the drinking water community and public health organizations have endeavored to craft regulations and guidelines on treatment and management practices that reduce risks from drinking water, specifically human pathogens. During this period there also evolved misunderstandings as to potential health risk associated with microorganisms that may be present in drinking waters. These misunderstanding or "myths" have led to confusion among the many stakeholders. The purpose of this article is to provide a scientific- and clinically-based discussion of these "myths" and recommendations for better ensuring the microbial safety of drinking water and valid public health decisions.

    This statement is intended to inform pediatricians and other health care professionals, parents, superintendents, and school board members about nutritional concerns regarding soft drink consumption in schools. Potential health problems associated with high intake of sweetened drinks are 1) overweight or obesity attributable to additional calories in the diet; 2) displacement of milk consumption, resulting in calcium deficiency with an attendant risk of osteoporosis and fractures; and 3) dental caries and potential enamel erosion. Contracts with school districts for exclusive soft drink rights encourage consumption directly and indirectly. School officials and parents need to become well informed about the health implications of vended drinks in school before making a decision about student access to them. A clearly defined, district-wide policy that restricts the sale of soft drinks will safeguard against health problems as a result of overconsumption.

    2014-12-01

    Approximately 37% of college students report heavy episodic drinking (5 or more drinks in an occasion for men and 4 or more for women) in the past month. This pattern of drinking is often associated with high blood alcohol levels, accidents, injuries, and negative social and academic outcomes. There is a need for novel theoretical approaches to guide prevention efforts. Behavioral economics emphasizes the role of contextual determinants, such as drink price and the presence and amount of alternative reinforcement as determinants of drinking levels and has received strong empirical support in basic laboratory research. This translational research study used a hypothetical behavioral economic measure to investigate the impact of a variety of next-day responsibilities on night-before drinking intentions in a sample of first-year college students (N = 80; 50% female) who reported recent heavy episodic drinking. Drinking estimates were significantly lower in all of the responsibility conditions relative to the no-responsibility condition; internships were associated with the greatest reduction (d(rm) = 1.72), and earlier class times were associated with greater reductions in drinking intentions (d(rm) range = 1.22-1.35) than later class times (d(rm) range = 0.83-1.00). These results suggest that increasing morning responsibilities should be further investigated as a potential strategy to reduce drinking in college students. PMID:25402835

    Aims: There is sparse literature on drink alcohol content in developing countries. This study documented detailed information on drink sizes and ethanol content of alcoholic beverages consumed in three different parts of India. Methods: Data primarily from formative phases of studies on alcohol use patterns in the states of Delhi, Rajasthan and Goa are reported. Participant observation and semi-structured interviews with key informants and drinking respondents were used to assess different beverage types and to empirically measure actual drink sizes as poured. Investigation of ethanol content included the use of biochemical analyses, the alcoholmeter and the Analox Analyser AM3. Respondents interviewed in the post-formative phase in one study were also asked to define the volume of their drinks by indicating pour levels in select drinking vessels. Results: A wide range of alcoholic drinks were documented that varied in ethanol concentration across and within sites. Drink sizes, particularly for high-strength beverages, varied both by study site and respondent, with pours of distilled spirits on average being larger than standard measures. Conclusion: Estimates of both mean volume of alcohol consumption and heavy drinking amounts are influenced by variability in alcohol concentration and respondent-defined pour sizes. The variation in drink alcohol content found across Indian states indicates that prior to conducting quantitative surveys, preliminary work on sources of drink alcohol content variation should be undertaken to tailor measurement tools to specific beverages and drinking practices observed. Recommendations for alcohol research in developing countries are provided. PMID:18832137

    Efforts to discourage excessive alcohol use among young people can only be effective if the target audience is exposed to, attends to, and comprehends key messages. The aim of this study was to examine age and sex differences in drinking motives to better inform development of targeted interventions to reduce alcohol-related harm. Thirty individual interviews and 12 group interviews were conducted with English 13-25 year olds. Interviewees gave multiple motivations for drinking - especially those related to image and reputation, and played down the health implications of heavy drinking. Negative aspects of drinking - caring for drunk friends, being cared for when drunk and suffering through hangovers with friends - were considered to offer opportunities for closer interpersonal bonding than other social activities. Respondents distanced themselves from 'problem' drinkers, but disapproved of others' problematic drinking or antisocial behaviour. Narrative messages demonstrating the social consequences of excessive consumption were preferred to single, static messages emphasising risk or harm. Interviewees noted that interventions must use an engaging tone or pitch: they considered many campaigns to be patronising or preaching. A lack of consensus between age and sex groups highlighted a need for multifaceted, multi-modal approaches that utilise mobile technologies and new media.

    PubMed

    Rehm, J; Roerecke, M

    2013-01-01

    Alcohol consumption has been linked with considerable mortality, and reduction of drinking, especially of heavy drinking, has been suggested as one of the main measures to reduce alcohol-attributable mortality. Aggregate-level studies including but not limited to natural experiments support this suggestion; however, causality cannot be established in ecological analysis. The results of individual-level cohort studies are ambiguous. On the other hand, randomized clinical trials with problem drinkers show that brief interventions leading to a reduction of average drinking also led to a reduction of all-cause mortality within 1 year. The results of these studies were pooled and a model for reduction of drinking in heavy drinkers and its consequences for all-cause mortality risk was estimated. Ceteris paribus, the higher the level of drinking, the stronger the effects of a given reduction. Implications for interventions and public health are discussed. PMID:23531718

  5. Drinking consequences and subsequent drinking in college students over 4 years.

    PubMed

    Martinez, Julia A; Sher, Kenneth J; Wood, Phillip K

    2014-12-01

    There is some evidence that college student drinkers may continue drinking in the face of adverse consequences. We examined 2 hypotheses: (a) that this seemingly pathological behavior is a phenomenon of university life, occurring with consistency throughout the entirety of college, and (b) that individuals accumulate these consequences over multiple semesters in college. A sample of 3,720 students from a large Midwestern university was asked to complete surveys the summer before college and every semester thereafter for 4 years. Results showed that certain drinking-related consequences (e.g., blackouts, regretted sexual experiences) consistently predicted continued frequent heavy drinking in the following semester, even after controlling for sex, race, age, and previous-semester frequent heavy drinking (range of odds ratio = 1.17 to 1.45 across semesters, p < .01). Such potent consequences may predict subsequent drinking for a number of possible reasons that may be examined and addressed as they would pertain to specific protective behavioral strategy-related and cognitive interventions. Furthermore, consequences were accumulated over multiple semesters by notable proportions of students. For example, 13.8% of students reported blacking out 5 time-points or more--describing a full half or more of their college careers. Experimental studies which aim to modify students' perceptions of norms associated with these consequences may aid in developing interventions to reduce the burden of harm to students. In the broader context, and given the prevalence of students' accumulation of consequences, future study might aim to determine how and in what ways these findings describe either pathological or normative processes.

    Several decades of research show that lesbians are at risk for hazardous drinking. Compared with heterosexual women, lesbians are less likely to abstain from drinking, less likely to decrease their alcohol consumption as they age, and more likely to report alcohol-related problems. Stress associated with lesbian identity and reliance on lesbian or gay bars for socialization and support are frequently posited--but largely untested--explanations for lesbians' heightened risk. Results from general population studies indicate that patterns of alcohol use established early in the life-course or during life transitions influence later alcohol use and alcohol-related problems. Further, heavy-drinking peers, availability of alcohol, and drinking in particular social contexts--such as at bars and parties--are believed to contribute to heavier drinking and to alcohol-related problems. To better understand lesbians' risks for hazardous drinking, we examined relationships between retrospective accounts of drinking patterns and drinking contexts in the early stages of lesbian identity development and current drinking outcomes in a large sample of adult lesbians. Findings suggest that early drinking patterns and drinking contexts influence later alcohol use and have important implications for risk reduction and prevention among lesbians. PMID:19042906

    The aim of this survey study was to explore the influence of work on individual's drinking behavior. From October 1994 to March 1995, the present researchers implemented a self-administered questionnaire survey on workers in the manufacturing sector in Metropolitan Kaohsiung area, southern Taiwan. Of the 1,117 subjects selected, 668 (61.8%) stated that they had had one or more drinks during the preceding month. The average daily consumption of alcohol was 0.2 +/- 0.9 drinks (with a range of 0 to 12 drinks and a median of 0.02 drinks). In addition, 188 (28.8%) of the subjects reported having experienced drinking-related problems during the preceding month, and 35 respondents (5.2%) gave escape from job stress as the reason for their drinking in the preceding month. The result of multivariate analyses showed that workers who reported less autonomy in their job were more likely to experience drinking-related problems (odds ratio [OR] = 1.3) and to drinking for psychological relief (OR = 1.2); that workers who reported more demanding job conditions were more likely to drink for escape (OR = 2.5) but had lower levels of drinking (t = -2.5, p = 0.01); and that workers who reported high levels of job strain were more likely to experience drinking-related problems and to drink for relief but had lower levels of drinking. The details and implications of this result will be discussed.

    Research indicates a bidirectional association between heavy alcohol use and marital quality among couples. The current research extends previous research on the role of interpersonal perception by examining how partner drinking and perceiving one’s partner’s drinking as problematic are associated with subsequent marital outcomes. Moreover, we evaluated how perceiving one’s partner to have a drinking problem was associated with marital functioning, and whether that association differed based on the partner’s actual drinking. Married couples (N = 123 dyads) with at least one spouse who consumed alcohol regularly completed measures of alcohol use and consequences, the perception that their spouse’s drinking was problematic, and marital adjustment (i.e., relationship satisfaction, commitment, and trust). Results from actor-partner interdependence models using structural equations modeling indicated that for husbands, partner heavy drinking was associated with lower adjustment. Additionally, for husbands, perceiving their spouse had a drinking problem was associated with lower adjustment for both themselves and their wives. Moreover, significant interactions between partner drinking and the perception of partner drinking problem on marital adjustment emerged, controlling for amount of consumption. Specifically, perceiving one’s partner’s drinking as a problem was only negatively associated with relationship adjustment if the partner reported higher levels of heavy drinking. This pattern was stronger for husbands. Results illustrate the importance of interpersonal perception, gender differences, and the use of dyadic data to model the complex dynamic between spouses with regard to alcohol use and how it affects relationship outcomes.

    Objective: This study investigated relationships between local alcohol policies, enforcement, alcohol outlet density, adult alcohol use, and underage drinking in 50 California cities. Method: Eight local alcohol policies (e.g., conditional use permit, social host ordinance, window/billboard advertising) were rated for each city based on their comprehensiveness. Local alcohol enforcement was based on grants received from the California Alcoholic Beverage Control agency for enforcement of underage drinking laws. Outlet density was based on the number of on- and off-premise outlets per roadway mile. Level of adult alcohol use was ascertained from a survey of 8,553 adults and underage drinking (frequency of past-year alcohol use and heavy drinking) from surveys of 1,312 adolescents in 2009 and 2010. Multilevel regression analyses were conducted to examine the effects of policies, enforcement, and other community-level variables on adolescent drinking, controlling for youth demographic characteristics. Mediating effects of adolescents' perceived ease of obtaining alcohol, perceived enforcement, and perceived acceptability of alcohol use also were examined. Results: None of the eight local alcohol-policy ratings were associated with adolescent drinking. Funding for underage drinking enforcement activities was inversely related to frequency of past-year alcohol use, whereas outlet density and adult drinking were positively related to both past-year alcohol use and heavy drinking. These relationships were attenuated when controlling for perceived ease of obtaining alcohol, enforcement, and acceptability of alcohol use, providing evidence for mediation. Conclusions: Adolescent alcohol use and heavy drinking appear to be influenced by enforcement of underage drinking laws, alcohol outlet density, and adult alcohol use. These community-level influences may be at least partially mediated through adolescents' perceptions of alcohol availability, acceptability of alcohol use

    Study Goals To identify social processes that underlie the relationship of acculturation and heavy drinking behavior among Latinos who have immigrated to the Northeast United States of America (USA). Method Community-based recruitment strategies were used to identify 36 Latinos who reported heavy drinking. Participants were 48% female, 23 to 56 years of age, and were from South or Central America (39%) and the Caribbean (24%). Six focus groups were audiotaped and transcribed. Results Content analyses indicated that the social context of drinking is different in the participants’ countries of origin and in the United States. In Latin America, alcohol consumption was part of everyday living (being with friends and family). Nostalgia and isolation reflected some of the reasons for drinking in the USA. Results suggest that drinking in the Northeastern United States (US) is related to Latinos’ adaptation to a new sociocultural environment. Knowledge of the shifting social contexts of drinking can inform health interventions. PMID:20376331

    Although many studies have addressed adverse outcomes in children of parents with alcohol abuse/dependence, less is known about the possible long-term effects of more normative patterns of parental alcohol consumption, including drinking at lower risk levels and heavy episodic or binge drinking. The extent of harm from parental drinking may therefore be underestimated. With this research proposal, we describe a project that aims to assess possible long-term adverse effects of parental drinking by combining survey and nationwide registry data. Advantages of a longitudinal general population cohort design include that it allows for detailed information on parental drinking through survey data and identification of possible negative long-term health and social outcomes from exposure to parental drinking 1–19 years after exposure through continuously updated nationwide registers. The rich information available from combining survey and registry data allows us to take into account important confounders, mediators, and moderators. PMID:26688663

    We review types of public drinking water and bottled water and provide recommendations on the composition of water for infants. Water used with any of the commercial infant formulas in Spain should contain less than 25 mg/l of sodium. Drinking water must be boiled for a maximum of one minute (at sea level) to avoid excessive salt concentration. Bottled water need not be boiled. Fluoride content in drinking water should be less than 0.3 mg/l in first year of life to prevent dental fluorosis. Nitrate content in water should be less than 25 mg/l to prevent methemoglobinemia. Water with a calcium concentration of between 50 and 100 mg/l is a dietary source of calcium since it provides 24-56 % of the required daily intake in infancy.

    Focus groups were conducted with young Arab/Chaldeans (N = 82) from different ethno-religious groups (Chaldeans, Orthodox Christians, and Muslims) to explore the potential risk and the protective factors associated with the high level of binge (or episodic heavy) drinking among Arab/Chaldeans reported by general population surveys. Most of the participants were aware of and knowledgeable about the problem in their community. Themes identified as contributory factors consistent across ethno-religious groups included the availability of alcohol, the importance of family, conformity to group behavior, and social reasons. Differences included the context for drinking and gender roles. These findings can be used to tailor culturally appropriate interventions.

    2014-01-01

    Objective The present study examines the relationships among reasons for drinking, alcohol consumption, and alcohol-related consequences in two college-aged samples. Personal motivators such as mood enhancement and coping (tension reduction) have consistently been shown to predict problematic alcohol use, but because of the salient nature of social drinking in college, we hypothesized that social reasons for drinking would be most frequently endorsed and, in turn, predict negative consequences. Method Two distinct samples—119 coed adjudicated students sanctioned by the university for violating campus alcohol policy and 106 co-ed volunteer students—completed measures assessing alcohol consumption, reasons for drinking, and consequences. Differential effects between genders were examined. Results Social camaraderie (SC) was the most frequently endorsed reason for drinking. Regression analyses controlling for previous drinking revealed that social reasons for drinking predicted alcohol-related problems among female students in both samples. Additionally, SC was significantly correlated with every drinking measure and problem measure at 1 month for females in both the adjudicated and the volunteer groups. Total drinks, drinking days, and heavy episodic drinking events correlated with SC for males in the adjudicated sample. Conclusions For females, these results suggest a relationship between social reasons for drinking and alcohol-related consequences, which previous research has not identified. More research is needed to explore females’ reasons for drinking, accompanying problems, and the underlying psychosocial traits associated with these reasons. PMID:17446979

The waterborn transmission of all these parasites is possible (41). Surface water supplies used for drinking water are potential sources of contamination. Giardia lamblia and Cryptosporidium spp. have received great attention in industrialized countries during the last years because they are the etiological agents of waterborne diseases. The life cycles of Giardia lamblia and Cryptosporidium are described with a special reference to drinking water technologies aimed at removing these parasites. PMID:8253478

    Aims: To describe and discuss the alcohol drinking patterns of the younger generation of hospital doctors in Norway and Germany – respectively the abstainers, frequent drinkers, episodic heavy drinkers and hazardous drinkers. Methods: Data were collected in nationwide postal surveys among doctors in Norway (2000) and Germany (2006). A representative sample of 1898 German and 602 Norwegian hospital doctors aged 27–65 years were included in the analyses (N=2500). Alcohol drinking patterns were measured using the first three items of AUDIT in Norway and the AUDIT-C in Germany, scores of ≥5 (ranking from 0 to 12) indicating hazardous drinking. Episodic heavy drinking was defined by the intake of ≥60g of ethanol, on one occasion, at least once a week. Frequent drinkers were who drank alcoholic beverages at least twice a week. Abstainers were persons who drank no alcohol. The analyses were performed separately for age groups (27–44 years versus 45–65 years) and genders. Results: Compared to the age groups 45 to 65 years in the Norwegian and German samples, the younger age groups (27–44 years) tend to have higher rates of abstainers, higher rates of infrequent drinking of moderate amount of alcoholic drinks, lower rates of episodic heavy drinking and lower rates of hazardous drinking. Conclusion: The younger generation of hospital doctors in Norway and Germany showed tendencies to healthier drinking habits. Changes in professional life, and in the attitude towards alcohol consumption, may go some way towards explaining these findings. PMID:20200658

    1986-01-01

    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. PMID:3958660

    Underage drinking and its associated problems have profound negative consequences for underage drinkers themselves, their families, their communities, and society as a whole, and contribute to a wide range of costly health and social problems. There is increased risk of negative consequences with heavy episodic or binge drinking. Alcohol is a factor related to approximately 4,300 deaths among underage youths in the U.S. every year. Since the mid-1980s, the nation has launched aggressive underage drinking prevention efforts at the federal, state, and local levels, and national epidemiologic data suggest that these efforts are having positive effects. For example, since 1982, alcohol-related traffic deaths among youth aged 16-20 years have declined by 79%. Evidence-based or promising strategies for reducing underage drinking include those that limit the physical, social, and economic availability of alcohol to youth, make it illegal for drivers aged <21 years to drive after drinking, and provide mechanisms for early identification of problem drinkers. Strategies may be implemented through a comprehensive prevention approach including policies and their enforcement, public awareness and education, action by community coalitions, and early brief alcohol intervention and referral programs. This paper focuses on underage drinking laws and their enforcement because these constitute perhaps the most fundamental component of efforts to limit youth access to and use of alcohol.

    Pedersen, W

    1990-11-01

    In a study of 1230 Norwegian adolescents aged 14-19, the prevalence of participation in 'drinking games' and the consequences thereof were investigated. The findings indicate that drinking games are very common among Norwegian youth. Further, there is a substantially higher alcohol consumption among those who participate in these games than among other youth, even when we 'control' for other indicators of network 'wetness'. In particular, a high consumption of beer among the boys seems to be connected with these games. It seems reasonable to assume that the drinking games are of importance for many young people, in particular as a means of being accepted by social groups of the same age. The games provide an organized, yet exciting frame around the interaction. It seems reasonable to assume that the participants usually take part in the games as a result of an intention to drink. Even so, it might be argued that the games are probably often more than 'neutral tools' to fulfil this intention: first of all, the games involve intense contact precisely in connection with alcohol consumption. Secondly, we know from previous studies that match rates and role modelling in connection with consumption increase with an increase in the intensity of group member contact. Finally, the individual member loses control and steering of his/her own consumption to a large extent: consumption becomes to a large degree a function of other people's actions and the rules of the game in question.

    The relationship between alcohol drinking and the prognosis of nasopharyngeal carcinoma (NPC) is unknown. To investigate the prognostic value of alcohol drinking on NPC, this retrospective study was conducted on 1923 male NPC patients. Patients were classified as current, former and non-drinkers according to their drinking status. Furthermore, they were categorized as heavy drinkers and mild/none drinkers based on the intensity and duration of alcohol drinking. Survival outcomes were compared using Kaplan–Meier analysis and Cox proportional hazards model. We found that current drinkers had significantly lower overall survival (OS) rate (5-year OS: 70.2% vs. 76.4%, P < 0.001) and locoregional recurrence-free survival (LRFS) rate (5-year LRFS: 69.3% vs. 77.5%, P < 0.001) compared with non-drinkers. Drinking ≥14 drinks/week, and drinking ≥20 years were both independent unfavorable prognostic factors for OS (hazard ratio [HR] = 1.38, 95% confidence interval [CI] 1.05–1.81, P = 0.022; HR = 1.38, 95% CI 1.09–1.75, P = 0.007). Stratified analyses further revealed that the negative impacts of alcohol were manifested mainly among older patients and among smokers. In conclusion, alcohol drinking is a useful predictor of prognosis in male NPC patients; drinkers, especially heavy drinkers have poorer prognosis. PMID:26776301

    Objective: Topiramate has been shown to reduce drinking and heavy drinking in alcohol-dependent individuals whose goal was to stop drinking. The present study evaluated the efficacy and tolerability of topiramate in heavy drinkers whose treatment goal was to reduce drinking to safe levels. Method: We randomly assigned 138 individuals (62.3% male) to receive 12 weeks of treatment with topiramate (N=67), at a maximal daily dosage of 200 mg, or matching placebo (N=71), both groups receiving brief counseling to reduce drinking and increase abstinent days. We hypothesized that topiramate-treated patients would be better able to achieve these goals and predicted that, based on prior research, the effects would be moderated by a single nucleotide polymorphism (rs2832407) in GRIK1, encoding the kainate GluK1 receptor subunit. Results: The rate of treatment completion was 84.9% and equal by treatment group. Topiramate treatment significantly reduced heavy drinking days (p<0.001) and increased abstinent days (p=0.032) relative to placebo. The topiramate group also had lower concentrations of the liver enzyme γ-glutamyltranspeptidase and lower scores on a measure of alcohol-related problems than the placebo group. In a European-American subsample (N=122), topiramate’s effect on heavy drinking days (p=0.004) was significantly greater than for placebo only in rs2832407 C-allele homozygotes. Conclusions: These findings support the use of topiramate 200 mg/day to reduce heavy drinking in problem drinkers. The moderator effect of rs2832407, if validated, would facilitate the identification of heavy drinkers who are likely to respond well to topiramate treatment and provide an important personalized treatment option. The pharmacogenetic findings also implicate the kainate receptor in the mechanism of topiramate’s effects on heavy drinking. www.clinicaltrials.gov registration: NCT00626925 PMID:24525690

    The aim of this paper is to shed light on the nature of underage problem drinking by using an empirically based method to characterize the variation in patterns of drinking in a community sample of underage drinkers. A total of 4056 16-20-year-old current drinkers from 212 communities in the US were surveyed by telephone as part of the National Evaluation of the Enforcing Underage Drinking Laws (EUDL) Program. Latent class models were used to create homogenous groups of drinkers with similar drinking patterns defined by multiple indicators of drinking behaviors and alcohol-related problems. Two types of underage problem drinkers were identified; risky drinkers (30%) and regular drinkers (27%). The most prominent behaviors among both types of underage problem drinkers were binge drinking and getting drunk. Being male, other drug use, early onset drinking and beliefs about friends drinking and getting drunk were all associated with an increased risk of being a problem drinker after adjustment for other factors. Beliefs that most friends drink and current marijuana use were the strongest predictors of both risky problem drinking (OR=4.0; 95% CI=3.1, 5.1 and OR=4.0; 95% CI=2.8, 5.6, respectively) and regular problem drinking (OR=10.8; 95% CI=7.0, 16.7 and OR=10.2; 95% CI=6.9, 15.2). Young adulthood (ages 18-20) was significantly associated with regular problem drinking but not risky problem drinking. The belief that most friends get drunk weekly was the strongest discriminator of risky and regular problem drinking patterns (OR=5.3; 95% CI=3.9, 7.1). These findings suggest that underage problem drinking is most strongly characterized by heavy drinking behaviors which can emerge in late adolescence and underscores its association with perceptions regarding friends drinking behaviors and illicit drug use.

    Numerous epidemiological studies have disclosed documented evidence that light to moderate consumption of any alcoholic beverage is associated with approximately 20% reduction in cardiovascular disease risk. This finding applies to both men and women and to healthy individuals as well as those with coronary heart disease, diabetes, hypertension, or heart failure. Nevertheless, the issue of including a recommendation for mild to moderate alcohol consumption within the routine recommendations for primary and secondary prevention of coronary heart disease is still controversial. The controversy is derived partly from methodological issues and partly from documented adverse health effects of excessive alcohol drinking. The key issue is the definition of the optimal dose of alcohol which guarantees a positive benefit-risk ratio, i.e. enjoying the benefits of alcohol without substantial risk. The accumulating scientific evidence shows that a daily consumption of less than 30 grams of alcohol for men and less than 15 grams for women is compatible with the above goal and is not associated with health risks. Therefore, for most individuals it is appropriate to recommend mild to moderate alcohol consumption as part of a healthy life style for the prevention of cardiovascular disease. Recommendations should be given on an individual basis, taking into account the patient's age, gender, physical and mental health status, personality and past drinking habits. The desirable quantity and its upper limit as well as drinking patterns should be clearly defined. All persons should be warned to avoid heavy drinking. Awareness of indications for abstinence from alcohol such as pregnancy, sport activity and the use of certain medications is highly important.

    When a person consumes ethanol, the body quickly begins to convert it to acetic acid, which circulates in the blood and can serve as a source of energy for the brain and other organs. This study used 13C magnetic resonance spectroscopy to test whether chronic heavy drinking is associated with greater brain uptake and oxidation of acetic acid, providing a potential metabolic reward or adenosinergic effect as a consequence of drinking. Seven heavy drinkers, who regularly consumed at least 8 drinks per week and at least 4 drinks per day at least once per week, and 7 light drinkers, who consumed fewer than 2 drinks per week were recruited. The subjects were administered [2-13C]acetate for 2 hours and scanned throughout that time with magnetic resonance spectroscopy of the brain to observe natural 13C abundance of N-acetylaspartate (NAA) and the appearance of 13C-labeled glutamate, glutamine, and acetate. Heavy drinkers had approximately 2-fold more brain acetate relative to blood and twice as much labeled glutamate and glutamine. The results show that acetate transport and oxidation are faster in heavy drinkers compared with that in light drinkers. Our finding suggests that a new therapeutic approach to supply acetate during alcohol detoxification may be beneficial. PMID:23478412

    Energy drinks are widely consumed by adolescents as these claim to improve performance, endurance and alertness. Recent reports have shown that there are no real health benefits of these drinks. On the contrary, certain adverse effects due to energy drinks have come to the forefront, casting a big question-mark on their safety and utility. This review discusses the present status of energy drinks, their active ingredients and their safety. We conclude that energy drinks, despite having some short pleasant effects, can be harmful for the body and are best avoided.

    This study examines patterns of alcohol use among undergraduates at a moderate-size university in the deep South. The results reveal that 84% of the students consumed alcohol and that Infrequent, Light, and Moderate drinking was the rule. However, 14% of the students were Heavy Drinkers, who were primarily White males, from each academic level, and fraternity members. The drinking circumstances and the complications which resulted from use varied between the drinking types. Heavy drinkers began to drink at the elementary and middle school age levels, and were introduced to alcohol outside the home. Moreover, the greater the quantity and frequency of alcohol consumption, the greater the likelihood of experiencing alcohol-related problems regardless of an individual's sex, race, or year in college.

    Aims Research has shown that alcohol outcome expectancies are predictive of heavy alcohol consumption, which can lead to risky behavior. The purpose of the present study was to assess the incidence of various low-risk social behaviors while drinking among college students. Such social behaviors may later be regretted (referred to as regrettable social behaviors) and include electronic and in-person communications. Methods College students (N = 236) completed measures of alcohol outcome expectancies and regrettable social behaviors. Results Regrettable social behaviors were reported by 66.1% of participants, suggesting that they may occur at a much higher rate than more serious drinking-related consequences (e.g. drinking and driving, violence, etc.). Expectancies for social facilitation predicted regrettable social behavior. Further, this relationship was mediated by amount of alcohol consumed. Conclusion Given the high incidence, regrettable social behaviors may be effective targets in alcohol prevention programming. PMID:25820611

    Objective: The promotion of drinking behaviors correlates with increased drinking behaviors and intent to drink, especially when peers are the promotion source. Similarly, online displays of peer drinking behaviors have been described as a potential type of peer pressure that might lead to alcohol misuse when the peers to whom individuals feel attached value such behaviors. Social media messages about drinking behaviors on Twitter (a popular social media platform among young people) are common but understudied. In response, and given that drinking alcohol is a widespread activity among young people, we examined Twitter chatter about drinking. Method: Tweets containing alcohol- or drinking-related keywords were collected from March 13 to April 11, 2014. We assessed a random sample (n = 5,000) of the most influential Tweets for sentiment, theme, and source. Results: Most alcohol-related Tweets reflected a positive sentiment toward alcohol use, with pro-alcohol Tweets outnumbering anti-alcohol Tweets by a factor of more than 10. The most common themes of pro-drinking Tweets included references to frequent or heavy drinking behaviors and wanting/needing/planning to drink alcohol. The most common sources of pro-alcohol Tweets were organic (i.e., noncommercial). Conclusions: Our findings highlight the need for online prevention messages about drinking to counter the strong pro-alcohol presence on Twitter. However, to enhance the impact of anti-drinking messages on Twitter, it may be prudent for such Tweets to be sent by individuals who are widely followed on Twitter and during times when heavy drinking is more likely to occur (i.e., weekends, holidays).

    Objective: Although alcohol consumption and sexual risk taking are associated, not everyone who drinks alcohol engages in risky sexual behavior. The purposes of the present study were to identify patterns of alcohol use behaviors and alcohol expectancies among women who are non–problem drinkers and to examine how these patterns are associated with indices of sexual risk. Method: Data from 758 non–problem drinking women who have sex with men and were not in committed relationships were analyzed using latent profile analysis to determine patterns of alcohol use and alcohol-related expectancies. Results: Of the four patterns observed, three classes had similar alcohol-related expectancies but differed with respect to drinking behavior (moderate drinking, regular heavy episodes, and frequent heavy episodes), and the fourth class consisted of moderate drinkers with low expectancies (low expectancies). Results revealed that those in the frequent heavy episodes class had the greatest number of sexual partners in the past year and drank the most alcohol before having sex compared with the other women. Both the regular and frequent heavy episodes classes reported greater likelihood of having unprotected sex in the future, more positive beliefs about casual sex, and greater subjective intoxication before having sex than women in the moderate drinking or low expectancies classes. Women in the low expectancies class reported less positive beliefs about condoms than those in the moderate drinking and regular heavy episodes classes. Conclusions: Results suggest that different patterns of expectancies and drinking behaviors are associated with different indices of sexual risk taking and highlight the importance of individually tailored programs for prevention of sexually transmitted infections.

    A limited number of studies have examined the co-occurrence of alcohol use and smoking and their mental health effects in middle and late life. In this study, using the 2008 National Survey of Drug Use and Health, the characteristics of individuals aged 50 and older who abstained from both substances, who used both substances, and who used one or the other substance were examined. Then, the main and interaction effects of drinking and smoking on psychological distress were analyzed. Findings show that smoker-nondrinkers are the most disadvantaged group in terms of sociodemographic and health characteristics, while drinker-nonsmokers are the most advantaged group. When sociodemographic, health, and other factors were controlled, no direct effects of drinking or interaction effect of drinking and smoking were detected for either gender. However, heavy smoking (6+ cigarettes on a typical smoking day) was significantly associated with an elevated level of psychological distress among women. The findings highlight the vulnerability of heavy smoking middle-aged and older women. These women are the most psychologically distressed and may need interventions designed to help them quit smoking, reduce or quit drinking, and alleviate psychological distress.

    This study evaluated benefit finding as a moderator of the relationship between spiritual and religious attitudes and drinking. Previous research indicates that undergraduates who drink heavily experience negative alcohol-related consequences. Literature also suggests that spirituality and religiosity (S/R) are protective against heavy drinking (e.g., Yonker, Schnabelrauch, & DeHaan, 2012) and that finding meaning, which is conceptually related to benefit finding, is negatively associated with alcohol use (e.g., Wells, 2010). Seven hundred undergraduate students completed the study materials including measures of drinking, benefit finding, and S/R. Based on previous research, we expected that S/R and benefit finding would be negatively associated with drinking. Furthermore, we expected that benefit finding would moderate the association between S/R and drinking, such that S/R would be more negatively associated with drinking among those higher in benefit finding. Consistent with expectations, a negative association between S/R and drinking was present, and was stronger among those high in benefit finding. These findings extend previous research by demonstrating that the protective effect of S/R on drinking appears to be particularly true among those who find benefit following stressful experiences. This study extends previous research showing that S/R is negatively associated with drinking by evaluating benefit finding (measured via the Post-Traumatic Growth Inventory; Tedeschi & Calhoun, 1996) as a potential moderator of the relationship between S/R and drinking. This study contributes to the alcohol literature seeking to understand and identify individual factors in drinking and determine how S/R and benefit finding relate to drinking.

    Animals with incomplete cheeks (i.e. dogs and cats) need to move fluid against gravity into the body by means other than suction. They do this by lapping fluid with their tongue. When a dog drinks, it curls its tongue posteriorly while plunging it into the fluid and then quickly withdraws its tongue back into the mouth. During this fast retraction fluid sticks to the ventral part of the curled tongue and is drawn into the mouth due to inertia. We show several variations of this drinking behavior among many dog breeds, specifically, the relationship between tongue dynamics and geometry, lapping frequency, and dog weight. We also compare the results with the physical experiment of a rounded rod impact onto a fluid surface. Supported by NSF PoLS #1205642.

    Historical trends in alcohol use among U.S. adolescents, as well as data regarding alcohol-related traffic fatalities among youth, indicate decreases in alcohol use. Nevertheless, alcohol use patterns still indicate high rates of binge drinking and drunkenness and the co-occurrence of alcohol use among youth with risky sexual activity, illicit substance use, and poor school performance. This article discusses unique elements of alcohol use among adolescents relative to adults that pose risks for alcohol misuse and alcohol-related problems. These differences range from patterns of drinking to differential sensitivity to alcohol. Developmental differences between adolescents and adults also are discussed with regard to age-normative developmental tasks and distinctions in brain development that may affect differences in drinking patterns. Epidemiologic findings on sexual-minority youth are provided, as are global trends in alcohol use among early adolescents and youth. It is proposed that using information about differences between youth and adults will be helpful in directing future etiologic and intervention research by capitalizing on unique biological, psychological, and social factors that may affect the success of efforts to reduce alcohol use among early adolescents and youth.

    The authors conducted two randomized clinical trials with ethnically diverse samples of college student drinkers in order to determine (a) the relative efficacy of two popular computerized interventions versus a more comprehensive motivational interview approach (BASICS) and (b) the mechanisms of change associated with these interventions. In Study 1, heavy drinking participants recruited from a student health center (N = 74, 59% women, 23% African American) were randomly assigned to receive BASICS or the Alcohol 101 CD-ROM program. BASICS was associated with greater post-session motivation to change and self-ideal and normative discrepancy relative to Alcohol 101, but there were no group differences in the primary drinking outcomes at 1-month follow-up. Pre to post session increases in motivation predicted lower follow-up drinking across both conditions. In Study 2, heavy drinking freshman recruited from a core university course (N = 133, 50% women, 30% African American) were randomly assigned to BASICS, a web-based feedback program (e-CHUG), or assessment-only. BASICS was associated with greater post-session self-ideal discrepancy than e-CHUG, but there were no differences in motivation or normative discrepancy. There was a significant treatment effect on typical weekly and heavy drinking, with participants in BASICS reporting significantly lower follow-up drinking relative to assessment only participants. In Study 2, change in the motivation or discrepancy did not predict drinking outcomes. Across both studies, African American students assigned to BASICS reported medium effect size reductions in drinking whereas African American students assigned to Alcohol 101, e-CHUG, or assessment did not reduce their drinking.

    Obesity prevalence is increasing all over the world. Most affected are people changing from a traditional lifestyle to an environment with both availability of high energy diet and less physical activity. Glycemic index (GI) is a measure of dietary glycemic carbohydrates, representing their ability to raise blood glucose concentrations. It refers to the postprandial blood glucose response expressed as a percentage of the response to a reference food (glucose or white bread) containing the same carbohydrate content. Given the present high consumption of sugary drinks, the putative contribution of these products to obesity deserves investigation. The aim of this study was to determine the GI of some drinks from the Portuguese market. Postprandial glycemia after ingestion of apple Frutis, peach Frutis, Green tea Frutea, green tea, black tea, lupin infusion, rooibos infusion, raftilose solution or bran solution has been determined for two hours in a caucasian population of young adults of any sex, 17 to 24 years of age. Apple Frutis GI was found to be 54.3, i.e., a low GI; Frutea Green tea had a GI of 64.7, considered as a moderate GI; peach Frutis showed a high GI, 86.6. Green and Black teas as well as rooibos and lupin infusions, all with added glucose (25 g), did not change glycemic response in comparison with the reference solution (water with 25 g glucose). No differences were seen after raftilose and bran solutions by comparison with the reference solution. GI information may help the choice of carbohydrates to include in a healthy diet. Formerly considered as a parameter of interest to diabetic patients, it may actually interest anybody concerned with a healthy diet. This study has been performed by medical and nutritional science students, who observed glycemic excursions in themselves, after drink ingestion. This experiment allowed them to see the impressive rise of glycemia after ingestion of a sugary drink, by comparison with basal levels which would not

    This paper attempts to investigate the stabilization behaviours of heavy metals in ceramsite made from wastewater treatment sludge (WWTS) and drinking-water treatment sludge (DWTS). Leaching tests were conducted to find out the effects of sintering temperature, (Fe(2)O(3) + CaO + MgO)/(SiO(2) + Al(2)O(3)) (defined as F/SA ratios), pH, and oxidative condition. Results show that sintering exhibits good binding capacity for Cd, Cr, Cu, and Pb in ceramsite and leaching contents of heavy metals will not change above 1000 degrees C. The main crystalline phases in ceramsite sintered at 1000 degrees C are kyanite, quartz, Na-Ca feldspars, sillimanite, and enstatite. The main compounds of heavy metals are crocoite, chrome oxide, cadmium silicate, and copper oxide. Leaching contents of Cd, Cu, and Pb increase as the F/SA ratios increase. Heavy metals in ceramsite with variation of F/SA ratios are also in same steady forms, which prove that stronger chemical bonds are formed between these heavy metals and the components. Leaching contents of heavy metals decrease as pH increases and increase as H(2)O(2) concentration increases. The results indicate that when subjected to rigorous leaching conditions, the crystalline structures still exhibit good chemical binding capacity for heavy metals. In conclusion, it is environmentally safe to use ceramsite in civil and construction fields. PMID:20219229

    The safety of drinking water is evaluated by the results obtained from faecal indicators during the stipulated controls fixed by the legislation. However, drinking-water related illness outbreaks are still occurring worldwide. The failures that lead to these outbreaks are relatively common and typically involve preceding heavy rain and inadequate disinfection processes. The role that classical faecal indicators have played in the protection of public health is reviewed and the turning points expected for the future explored. The legislation for protecting the quality of drinking water in Europe is under revision, and the planned modifications include an update of current indicators and methods as well as the introduction of Water Safety Plans (WSPs), in line with WHO recommendations. The principles of the WSP approach and the advances signified by the introduction of these preventive measures in the future improvement of drinking water quality are presented. The expected impact that climate change will have in the quality of drinking water is also critically evaluated.

    We sought to 1) describe the settings or groups of settings where men who have sex with men (MSM) consume alcohol in 16 U.S. metropolitan statistical areas (MSA); and 2) investigate whether certain drinking settings or groups of settings are associated with higher levels of alcohol consumption, problem drinking, and sexual risk behavior. Latent class analysis was used to develop our measure of drinking settings. The final latent class model consisted of four distinct classes which captured the typical settings where MSM consumed alcohol: “home” “social,” “bar/social,” and “general” drinkers (i.e., drinks in all settings). Regression models showed that “general” drinkers were more likely than “social” drinkers to engage in frequent heavy drinking. Compared to `social' drinkers, general drinkers were also more likely to engage in unprotected anal intercourse (UAIMP) and UAIMP with men met in bars and other venues (e.g., private parties, bath houses) while intoxicated. Assessment of drinking settings may be a means of identifying MSM who are at greater risk for frequent, heavy drinking and related sexual risk behavior. PMID:23261495

    Rationale Adolescent binge drinking is concerning, as important neurodevelopments occur during this stage. Previous research suggests that binge drinking may disrupt typical brain development, and females may be particularly vulnerable. Objectives We used magnetic resonance imaging (MRI) to examine cortical thickness in adolescent females and males with and without histories of binge drinking. Methods Participants (N=59) were 16–19-year-old adolescents recruited from local schools. Recent binge drinkers (n=29, 48% female) were matched to non-drinkers (n=30, 50% female) on age, gender, pubertal development, and familial alcoholism. Participants completed a neuropsychological battery and MRI session. Cortical surfaces were reconstructed with FreeSurfer. Results Binge × gender interactions (p<.05) were seen for cortical thickness in four left frontal regions: frontal pole, pars orbitalis, medial orbital frontal, and rostral anterior cingulate. For all interactions, female bingers had thicker cortices than female controls, while male bingers had thinner cortices than male controls. Thicker left frontal cortices corresponded with poorer visuospatial, inhibition, and attention performances for female bingers (r=−0.69 to 0.50, p<0.05) and worse attention for male bingers (r=−0.69, p=0.005). Conclusions Adolescent females with recent binge drinking showed ~8% thicker cortices in left frontal regions than demographically similar female non-drinkers, which was linked to worse visuospatial, inhibition, and attention performances. In contrast, adolescent binge-drinking males showed ~7% thinner cortices in these areas than non-drinking males. These cross-sectional data suggest either different gray matter risk factors for males as for females toward developing heavy drinking, or differential adverse sequelae. PMID:21952669

    College student alcohol consumption is a major concern, and is known to increase during the celebration of special events. This study examined a student-constructed holiday, State Patty's Day, at a university with a dominant drinking culture using three sources of data - coded data from Facebook groups, daily web surveys from first-year students (N= 227, 51% male, age 18 to 20; 27.3% Hispanic/Latino; of non-Hispanic/Latino, 26.9% of sample European American/White, 19.4% Asian American/Hawaiian/Pacific Islander, 15.9% African American/Black, 10.6% more than one race), and criminal offense data from police records. Results indicated that messages about State Patty's Day on Facebook focused on drinking and social aspects of the holiday, such as the social context of drinking, a sense of belonging to a larger community, and the social norms of drinking. These messages were rarely about consequences and rarely negative. On State Patty's Day, 51% of students consumed alcohol, compared to 29% across other sampled weekend days. Students consumed more drinks (M = 8.2 [SD = 5.3] drinks per State Patty's Day drinker) and were more likely to engage in heavy drinking on State Patty's Day, after controlling for gender, drinking motives, and weekend, demonstrating the event-specific spike in heavy drinking associated with this holiday. The impact of this student-constructed holiday went beyond individual drinking behavior; alcohol-specific and other crime also peaked on State Patty's Day and the day after. Event-specific prevention strategies may be particularly important in addressing these spontaneous, quickly-constructed, and dynamic events. PMID:22685369

    Young people consume alcohol almost exclusively in social contexts, but natural drinking group dynamics are poorly understood. Our research focuses on the drivers' role within natural drinking groups. We conducted breath-test surveys of existing groups of young people at the US/Mexico border crossing before they headed to Tijuana bars, and surveyed them again upon their return. Results indicated an individual's perception of other group member's drinking plans predicts drinking intentions to a greater degree for passengers than drivers. Additionally, drivers who anticipated heavy drinking among other group members returned to the United States with BACs nearly identical to drivers who reported that other group members would not drink at all. This suggests drivers were resistant to normative pressures to drink. Evidence that group-dynamic variables may impact drinking behavior underscores the importance of systematic exploration of natural drinking groups. Furthermore, the knowledge gleaned from studying the dynamics and decision making processes of natural drinking groups could be used to design intervention designed to increase designated driver use and to reduce drinking among designated drivers.

    Background In order to identify drinking contexts towards which prevention efforts should be directed, associations of context-specific alcohol use (past-year frequency of drinking and heavier drinking in the context) with a range of alcohol-related problems were examined in a population sample of adolescents. Methods A sample of youths (ages 15–18) residing in 50 medium-to-large California cities (n=473 drinkers) was obtained. Respondents provided information about seven past-year alcohol-related problems in three domains (physiological consequences, alcohol-related violence, and conflict/trouble) and the number of times in the past year they used six distinct drinking contexts (parties, restaurants/bars, parking lots/street corners, beaches/parks, respondent’s home without parents, someone else’s home without parents). Context-specific dose-response was estimated for each context using censored Tobit models with heteroskedasticity corrections Results Physiological problems were associated with more frequent drinking in five of six contexts. Heavier drinking in restaurants/bars/nightclubs (b=0.22, s.e.=0.10) and someone else’s home without parents (b=0.14, s.e.=0.06) was associated with greater risk of violence. Conflict/trouble was associated with more frequent drinking in parking lots/street corners, declining at higher levels of drinking. Conclusions Certain drinking contexts are related to problems amongst youths, some because they are associated with frequent alcohol consumption and others because they are associated with heavier drinking. Identifying which drinking contexts are related to specific alcohol-related problems and why is an essential component of developing effective preventive interventions. PMID:26208252

  4. Drinking patterns and problems and drinking in the injury event: an analysis of emergency room patients by ethnicity.

    While a substantial literature exists on the association of alcohol consumption and injury, less is known about the context in which drinking occurs within specific ethnic groups in the United States. This paper analyzes drinking patterns, alcohol-related problems and drinking-in-the-event variables among a probability sample of 359 black, 528 Hispanic and 458 white patients who were breathalyzed and interviewed after admission to the emergency room. Injured patients among both Hispanics and whites were more likely to be positive on the breathalyzer and to report heavy drinking and more frequent drunkenness during the preceding year than their non-injured counterparts. Blacks were less likely than either Hispanics or whites to report a larger number of drinks prior to injury, feeling drunk at the time, or a causal association of alcohol and the injury event. These data suggest a differential role of alcohol in injury occurrence within ethnic groups, with alcohol possibly playing less of a role in the injury event for blacks than for Hispanics or whites.

    Primary health providers in the community must be able to field questions and guide vulnerable populations to informed decisions about drinking water quality and health. This article offers an overview of selected contaminants in drinking water and their possible effects on the health of women over the life span. Historical concerns for drinking water safety, which led to the development of current drinking water regulations, are briefly explored. Several chemical, microbial, and radionuclide contaminants of particular concern to women and children are discussed. Short- and long-term tap water alternatives are suggested for when tap water is deemed unsuitable for use.

    The daily drinking of three liters of water with meals, for a period of five days, by a man twenty-two years of age who was in a condition of nitrogen equilibrium through the ingestion of a uniform diet, was productive of the following findings : 1. An increase in body weight, aggregating two pounds in five days. 2. An increased excretion of urinary nitrogen, the excess nitrogen being mainly in the form of urea, ammonia, and creatine. 3. A decreased excretion of creatinine and the coincident appearance of creatine in the urine. The decreased creatinine output is believed to indicate that the copious water drinking has stimulated protein catabolism. The appearance of creatine is considered evidence that the water has caused a partial muscular disintegration resulting in the release of creatine, but not profound enough to yield the total nitrogen content of the muscle. The output of creatine is, therefore, out of all proportion to the increase in the excretion of total nitrogen. 4. An increased output of ammonia which is interpreted as indicating an increased output of gastric juice. 5. A decreased excretion of feces and of fecal nitrogen, the decrease in the excretion of fecal nitrogen being of sufficient magnitude to secure a lowered excretion of both the bacterial and the non-bacterial nitrogen. 6. A decrease in the quantity of bacteria excreted daily. 7. An increase in the percentage of total nitrogen appearing as bacterial nitrogen. 8. A lower creatinine coefficient. 9. A more economical utilization of the protein constituents of the diet. 10. The general conclusion to be reached as the result of this experiment is to the effect that the drinking of a large amount of water with meals was attended by many desirable and by no undesirable features.

    The purpose of this study was to evaluate alcohol consumption among adolescents from Tucuman, Argentina, and to determine its possible relationship with increased levels of blood pressure. Three hundred fifty-six students aged 13-18 included in the study were asked to answer questionnaires anonymously. Two blood pressures measures were then taken. Differences between both sexes were found in quantity and frequency of alcohol consumption. Enjoyment was determined to be the main reason for drinking. There was an association between frequency and alcohol-related problems, and smoking habits. There were also differences in blood pressure among males and females. A weak, but significant, relationship between quantity/frequency index and diastolic blood pressure was found. A greater prevalence of hypertension in male heavy drinkers was noted as well. Because this addiction implies multiple social problems and it also accounts for a hypertension risk factor, the importance of aiming at developing prevention strategies for alcohol abuse among adolescents is stressed.

    The present study predicts heavy alcohol use across the high school years (aged 14 through 18) from cognitions regarding the use of alcohol assessed in middle school. Using Latent Growth Modeling, we examined a structural model using data from 1011 participants in the Oregon Youth Substance Use Project. In this model, social images and descriptive norms regarding alcohol use in grade 7 were related to willingness and intention to drink alcohol in grade 8 and these variables were subsequently related to the intercept and slope of extent of heavy drinking across the high school years (grades 9 through 12). Across the sample, both descriptive norms and social images influenced the intercept of heavy drinking (in the 9th grade) through willingness to drink alcohol. Multiple sample analyses showed that social images also were directly related to the intercept of heavy drinking, for girls only. Results suggest that cognitions regarding alcohol use in middle school predict subsequent heavy drinking in high school. These findings emphasize the need for prevention programs targeting changing students' social images and encouraging a more accurate perception of peers' use when students are in middle school.

    Aims: The purpose of this study is to estimate the prevalence of alcohol use and alcohol-related consequences, identify drinking profiles using latent profile analysis (LPA), and investigate associations between profiles and violent victimization among young people in Mexico. Methods: LPA identified profiles of drinking behavior in a survey of entering first year university students. Multinomial and logistic regression examined associations between drinking patterns, socio-demographic variables and violent victimization. Results: The LPA identified five profiles of behaviors and consequences among the 22,224 current, former and never drinkers: Non/Infrequent-No Consequences, Occasional-Few Consequences, Regular-Some Consequences, Heavy-Many Consequences and Excessive-Many Consequences drinkers. The Occasional-Few Consequences profile comprised the largest, and the Excessive-Many Consequences profile the smallest, group of drinkers. Multinomial regression showed males and older students more likely to be Heavy or Excessive-Many Consequences drinkers. Living alone was associated with higher odds, and higher maternal education with lower odds, of being a Non/Infrequent-No Consequences drinker. Heavier drinking profiles were more likely to experience violent victimization adverse consequences. Logistic regression showed male and female Heavy and Excessive-Many Consequences drinkers had the highest odds, and Non/Infrequent drinkers the lowest odds, of experiencing any victimization. Conclusion: Findings suggest changes in male and female drinking behavior and a continuation of the established pattern of infrequent but high consumption among Mexican youths. Both male and female Heavy and Excessive-Many Consequences drinkers were at elevated risk for experiencing victimization. Identifying cultural gender norms about drinking including drinker expectations and drinking context that contribute to these patterns can inform prevention efforts. PMID:25534933

    This study explored the association between alienating job conditions and problem drinking within the context of occupational status and workplace drinking subculture. From December 1994 to March 1995, a questionnaire survey was implemented in the manufactory sector in southern Taiwan. Within the questionnaire, any perceived self-estrangement, powerlessness and social isolation that the individual experienced in his work were measured as the alienating job conditions, and any negative physical, psychological and social consequences the individual experienced during the previous month were considered as affecting problem drinking. Of the 1117 subjects, 668 (61.8%) reported imbibing one or more drinks during the preceding month; the average daily alcohol consumption being 0.2+/-0.9 drinks. In addition, 188 (16.8%) subjects reported having experienced drinking-related problems in the preceding month. Workers with low occupational status were more likely to become problem drinkers when they felt comparatively self-estranged in their work. Further, those with a family history including any habitual drinker or those under more encouraging workplace drinking subculture were more likely to have drinking-related problems. For the prevention of problem-related drinking behavior, the workplace should be considered as the focus of our future intervention and management program.

    Today's regulatory environment has led to the proliferation of voluntary consensus standards and certification programs that are important to ensuring safety and health in a number of areas. One such area -- the treatment and delivery of potable water -- is addressed by the Drinking Water Additives Program.'' At the request of the Environmental Protection Agency (EPA), this program was developed in the mid-1980s by an independent, voluntary consensus standards organization called NSF International (formerly known as the National Sanitation Foundation). This paper explains the need for and the structure of the Drinking Water Additives Program; the rationale for transferring responsibility for its execution from the EPA to the private sector; and the impact of its standards on users, manufacturers, and state and local regulatory bodies. Understanding the additives program is critically important to industry suppliers because, as it continues to gain greater awareness and acceptance, there are a growing number of manufacturers sourcing materials and products primarily from suppliers whose products meet the program's certification requirements.

    We develop a gendered marital biography approach-which emphasizes the accumulating gendered experiences of singlehood, marriage, marital dissolution, and remarriage-to examine the relationship between marital statuses and transitions and heavy alcohol use. We test this approach using individual-level (n = 10,457) and couple-level (n = 2,170) longitudinal data from the Health and Retirement Study, and individual-level (n = 46) and couple-level (n = 42) in-depth interview data. Quantitative results show that marriage, including remarriage, reduces men's but increases women's drinking relative to being never married and previously married, whereas divorce increases men's but decrease women's drinking, with some variation by age. Our qualitative findings reveal that social control and convergence processes underlie quantitative results. We call attention to how men's and women's heavy drinking trajectories stop, start, and change direction as individuals move through their distinctive marital biography. PMID:26957135

    2001-01-01

    The role of human excretion, drinking water, and deposition as a source of heavy metals to municipal sewage was investigated and compared with common levels in sludge for soil application. These sources contributed more than half of the copper (Cu), zinc (Zn), and lead (Pb) content of municipal sewage sludge for soil application, while other sources dominated the fluxes of chromium (Cr) and cadmium (Cd). Drinking water was an important source for Cu and Zn. Deposition contributed about 40% to the Pb flux. Faecal excretion commonly caused less than 10% of the heavy metal load, while urinary excretion was here a negligible heavy metal source.

    2015-01-01

    Background Prazosin (PRZ, an α1-adrenergic receptor antagonist) and naltrexone (NTX, a non-specific opioid receptor antagonist) each decrease alcohol drinking when administered to rats selectively-bred for high voluntary alcohol drinking (alcohol-preferring, or “P”), and the combination of PRZ+NTX decreases alcohol drinking more effectively than does either drug alone. Since drug responsiveness can depend on history of alcohol drinking and dependence, we investigated whether various schedules of PRZ and NTX administration, alone or in combination, are effective in decreasing alcohol drinking in male P rats with a history of protracted voluntary alcohol drinking, dependence and repeated withdrawals closely resembling human alcoholism. Methods Male P rats became alcohol-dependent during 1 year of ad libitum 24 h/day access to food, water and 20% alcohol with repetitive temporary alcohol withdrawals. Four sequential studies then addressed effects of oral PRZ (2 mg/kg) and NTX (10 mg/kg), alone or together, on alcohol drinking during: 1) daily alcohol access with daily drug treatment, 2) intermittent alcohol access with daily drug treatment, 3) intermittent alcohol access with occasional drug treatment, and 4) post-deprivation reinstatement of alcohol access. Results The combination of PRZ+NTX consistently suppressed alcohol drinking during daily or intermittent alcohol access conditions and when drug treatment was either daily or occasional. PRZ+NTX was consistently more effective than either drug alone. The reduction in alcohol drinking was not due to sedation, motor effects or malaise. Conclusions Both daily and “as-needed” treatment with PRZ+NTX are highly effective in suppressing daily, intermittent and post-deprivation alcohol drinking in male P rats with a protracted history of alcohol dependence and repeated withdrawals. This drug combination may be especially effective for treating individuals with long histories of heavy alcohol abuse, dependence and

    Abstract Question A 14-year-old boy came to my office to discuss his frequent consumption of energy drinks to enhance his performance at school and while playing soccer. What is the recommended use of energy drinks in children and is there any harm in consuming them? Answer Energy drinks are beverages with a high concentration of caffeine and additional stimulants. They are sold in numerous places and are easily accessed by children, adolescents, and young adults. Many reports warn about potential adverse effects associated with their consumption, especially in combination with alcohol among adolescents, and in combination with stimulant medications among children treated for attention deficit hyperactivity disorder. Children and adolescents should avoid energy drinks, and health care providers should educate youth and their parents about the risks of caffeinated drinks. PMID:24029508

    The focus of this paper is on informal control of drinking, indicated by criticism of people in the social network on someone's alcohol consumption. It studies country and gender differences in the extent drinkers suffering from typical symptoms of heavy or prolonged alcohol use report informal control from others (reactive informal control), and country and gender differences in the extent comments on someone's drinking are (also) directed at those who do not suffer from these symptoms (pro-active informal control). The data come from eighteen general population surveys, selected from an integrated dataset on drinking and drinking-related factors including more than 35 countries. The criteria for inclusion were that data for both men and women were available and that at least 3 items about symptoms of severe physiological consequences and about criticism of drinking had valid responses. The results show that men suffering from typical symptoms of heavy or prolonged alcohol use are more likely to be criticized than equivalent women (reactive control). Irrespective of gender, reactive informal control is more prevalent in poorer countries and in countries with a high proportion of abstainers. Concerning pro-active control, among women a larger part of criticism appeared to be directed at those who (as yet) do not suffer from symptoms typical for heavy or prolonged alcohol use. There is a lot of variation between countries in pro-active informal control. This variation is only weakly related to prosperity of a country but not to its proportion of abstainers. PMID:21691455

    Anthropogenic activities associated with industrialization, agriculture and urbanization have led to the deterioration in water quality due to various contaminants. To assess the status of urban drinking water quality, samples were collected from the piped supplies as well as groundwater sources from different localities of residential, commercial and industrial areas of Lucknow City in a tropical zone of India during pre-monsoon for estimation of coliform and faecal coliform bacteria, organochlorine pesticides (OCPs) and heavy metals. Bacterial contamination was found to be more in the samples from commercial areas than residential and industrial areas. OCPs like α,γ-hexachlorocyclohexane and 1,1 p,p-DDE {dichloro-2, 2-bis(p-chlorophenyl) ethene)} were found to be present in most of the samples from study area. The total organochlorine pesticide levels were found to be within the European Union limit (0.5 μg/L) in most of the samples. Most of the heavy metals estimated in the samples were also found to be within the permissible limits as prescribed by World Health Organization for drinking water. Thus, these observations show that contamination of drinking water in urban areas may be mainly due to municipal, industrial and agricultural activities along with improper disposal of solid waste. This is an alarm to safety of public health and aquatic environment in tropics.

    We investigated relationships between drinking, other drug use, and drug craving, using ecological momentary assessment (EMA), in a sample of polydrug users who were not heavy drinkers. In a prospective longitudinal cohort study, 114 heroin and cocaine users on methadone-maintenance treatment carried handheld electronic diaries during waking hours and were screened for drug and alcohol use for up to 25 weeks. Individuals who fulfilled the Diagnostic and Statistical Manual of Mental Disorders criteria for alcohol abuse or dependence were excluded. Participants responded to 2-5 random prompts per day to report on their moods, cravings, and activities and initiated entries when they used or acutely craved heroin or cocaine. Drinking alcohol was assessed in both types of entries. Breath alcohol was measured three times weekly. Participants reported drinking alcohol in 1.6% of random-prompt entries, 3.7% of event-contingent entries when craving cocaine and/or heroin, and 11.6% of event-contingent entries when using cocaine and/or heroin. Alcohol drinking was also associated with higher craving ratings and prestudy alcohol use. More drinking was detected by ambulatory self-report than by in-clinic breath testing. Even though we had screened out heavy drinkers from our sample of polydrug users, drinking was associated with heroin and cocaine craving and actual use. PMID:27579810

    Aims: Growing data reveals deficits in perception, understanding and regulation of emotions in alcohol dependence (AD). The study objective was to explore the relationships between emotional processing, drinking history and relapse in a clinical sample of alcohol-dependent patients. Methods: A group of 80 inpatients entering an alcohol treatment program in Warsaw, Poland was recruited and assessed at baseline and follow-up after 12 months. Baseline information about demographics, psychopathological symptoms, personality and severity of alcohol problems was obtained. The Schutte Self-Report Emotional Intelligence (EI) Test and Toronto Alexithymia Scale (TAS) were utilized for emotional processing assessment. Follow-up information contained data on drinking alcohol during the last month. Results: At baseline assessment, the duration of alcohol drinking was associated with lower ability to utilize emotions. Patients reporting more difficulties with describing feelings drank more during their last episode of heavy drinking, and had a longer duration of intensive alcohol use. A longer duration of the last episode of heavy drinking was associated with more problems identifying and regulating emotions. Poor utilization of emotions and high severity of depressive symptoms contributed to higher rates of drinking at follow-up. Conclusions: These results underline the importance of systematic identification of discrete emotional problems and dynamics related to AD. This knowledge has implications for treatment. Psychotherapeutic interventions to improve emotional skills could be utilized in treatment of alcohol-dependent patients. PMID:25543129

    2012-05-01

    The term "energy drink" designates "any product in the form of a drink or concentrated liquid, which claims to contain a mixture of ingredients having the property to raise the level of energy and vivacity". The main brands, Red Bull, Dark Dog, Rockstar, Burn, and Monster, are present in food stores, sports venues, and bars among other soft drinks and fruit juices. Their introduction into the French market raised many reluctances, because of the presence of taurine, caffeine and glucuronolactone. These components present in high concentrations, could be responsible for adverse effects on health. The association of energy drinks and spirits is widely found among adolescents and adults who justify drinking these mixed drinks by their desire to drink more alcohol while delaying drunkenness. Given the importance of the number of incidents reported among the energy drinks consumers, it seemed appropriate to make a synthesis of available data and to establish causal links between the use of these products and the development of health complications. For a literature review, we selected scientific articles both in English and French published between 2001 and 2011 by consulting the databases Medline, Embase, PsycINFO and Google Scholar. The words used alone or in combination are "energy dinks", "caffeine", "taurine", "toxicity", "dependence". An occasional to a moderate consumption of these drinks seems to present little risk for healthy adults. However, excessive consumption associated with the use of alcohol or drugs in amounts that far exceed the manufacturers recommended amount, could be responsible for negative consequences on health, particularly among subjects with cardiovascular disease.

    Objective: It has been well established that college students engage in heavy drinking during specific social events; however, within the general population, evidence of event-specific drinking has been largely indirect. The present study therefore aimed to investigate the temporal variability in daily alcohol consumption in the winter holiday months among residents of a large metropolitan area. Method: A random-digit-dialing telephone survey was conducted of residents who drank alcohol at least once per month. During a 5-week period beginning December 1, 2009, the number of drinks consumed on each day within the past week was collected for 578 participants. Results: Weekly variation in alcohol consumption peaked on Fridays and Saturdays and was particularly high on Christmas and New Year’s Eve. Mean drink consumption was significantly higher on Christmas and New Year’s Eve compared with most weekends within the sampling period. Conclusions: The present findings provide the first direct evidence, with temporal specificity, that alcohol consumption within the general population is highly event specific. Targeted intervention strategies similar to those used within college student samples may be appropriate for reducing or preventing alcohol-related harmful events on a population level.

    There is a need for novel, theory-based approaches to reduce heavy drinking on college campuses. Behavioral economics has guided basic laboratory research on drug administration for over 30 years and has recently been applied to human substance use in naturalistic and clinical settings. This paper provides an introduction to behavioral economics, reviews applications of behavioral economics to college student drinking, and describes prevention and intervention strategies that are consistent with behavioral economic theory. Behavioral economic theory predicts that college students' decisions about drinking are related to the relative availability and price of alcohol, the relative availability and price of substance-free alternative activities, and the extent to which reinforcement from delayed substance-free outcomes is devalued relative to the immediate reinforcement associated with drinking. Measures of problem severity are based on resource allocation towards alcohol and the relative value of alcohol compared to other reinforcers. Policy and individual level prevention approaches that are consistent with behavioral economic theory are discussed, including strategies for increasing the behavioral and monetary price of alcohol, increasing engagement in rewarding alternatives to substance use, and counteracting student drinkers' tendency to overvalue immediate relative to delayed rewards.

    The safety of drinking water is evaluated by the results obtained from faecal indicators during the stipulated controls fixed by the legislation. However, drinking-water related illness outbreaks are still occurring worldwide. The failures that lead to these outbreaks are relatively common and typically involve preceding heavy rain and inadequate disinfection processes. The role that classical faecal indicators have played in the protection of public health is reviewed and the turning points expected for the future explored. The legislation for protecting the quality of drinking water in Europe is under revision, and the planned modifications include an update of current indicators and methods as well as the introduction of Water Safety Plans (WSPs), in line with WHO recommendations. The principles of the WSP approach and the advances signified by the introduction of these preventive measures in the future improvement of dinking water quality are presented. The expected impact that climate change will have in the quality of drinking water is also critically evaluated. PMID:21318002

    In an attempt to validate the animal model of adjunctive ethanol drinking in people, human subjects were allowed access to ad lib beer while playing a game that delivered monetary reinforcements on a FI schedule. Subjects exposed to a longer FI schedule drank significantly more than those exposed to a shorter schedule, confirming the prediction made by the animal model. A pattern of ingestion characteristic of adjunctive drinking was also observed in the longer FI condition, providing evidence that ethanol drinking in humans can be schedule-induced. PMID:3249751

    This summer I had the opportunity to work in the Environmental Management Office (EMO) under the Chemical Sampling and Analysis Team or CS&AT. This team s mission is to support Glenn Research Center (GRC) and EM0 by providing chemical sampling and analysis services and expert consulting. Services include sampling and chemical analysis of water, soil, fbels, oils, paint, insulation materials, etc. One of this team s major projects is the Drinking Water Project. This is a project that is done on Glenn s water coolers and ten percent of its sink every two years. For the past two summers an intern had been putting together a database for this team to record the test they had perform. She had successfully created a database but hadn't worked out all the quirks. So this summer William Wilder (an intern from Cleveland State University) and I worked together to perfect her database. We began be finding out exactly what every member of the team thought about the database and what they would change if any. After collecting this data we both had to take some courses in Microsoft Access in order to fix the problems. Next we began looking at what exactly how the database worked from the outside inward. Then we began trying to change the database but we quickly found out that this would be virtually impossible.

    This study aimed to describe the households’ choices of drinking water sources, and evaluate the risk of human exposure to heavy metals via different drinking water sources in Chenzhou City of Hunan Province, Southern China. A cross-sectional face-to-face survey of 192 householders in MaTian and ZhuDui village was conducted. The concentrations of heavy metals in their drinking water sources were analyzed. Carcinogenic and non-carcinogenic risk assessment was performed according to the method recommended by the United States Environmental Protection Agency. In total, 52.60% of the households used hand-pressed well water, and 34.89% used barreled water for drinking. In total, 6.67% of the water samples exceeded the Chinese drinking water standards. The total health risk of five metals is 5.20 × 10−9~3.62 × 10−5. The total health risk of five metals was at acceptable levels for drinking water sources. However, the total risk of using hand-pressed well water’s highest value is 6961 times higher than the risk of using tap water. Household income level was significantly associated with drinking water choices. Arsenic (As) and lead (Pb) are priority controlled pollutants in this region. Using safe drinking water (tap water, barreled water and so on) can remarkably reduce the risk of ingesting heavy metals. PMID:26569281

    Three researchers from the Energy and Environmental Policy Center at Harvard University have come up with a new method of calculating the risk from contaminants in drinking water, one that they believe takes into account some of the uncertainties in pronouncing water safe or dangerous to drink. The new method concentrates on the risk of cancer, which authors Edmund Crouch, Richard Wilson, and Lauren Zeise believe has not been properly considered in establishing drinking water standards.Writing in the December 1983 issue of Water Resources Research, the authors state that “current [drinking water] standards for a given chemical or class of chemicals do not account for the presence of other pollutants” that could combine to create dangerous substances. According to Wilson, “Over a hundred industrial pollutants and chlorination byproducts have been found in various samples of drinking water, some of which are known carcinogens, others suspected carcinogens.” The same chlorine that solves one major health problem—the threat of bacterial disease—can thus contribute to another, according to the authors, by increasing the long-term risk of cancer. The largest risks are due to halomethanes such as chloroform and bromoform, produced as chlorine reacts with organic matter in drinking water.

    The aim of the study was to determine the role of alcoholic drinks as a potential source of dietary fluoride by means of measuring fluoride levels in selected alcoholic drinks available on the Polish market that are also diverse in terms of the percentage content of ethanol. The study was conducted on 48 types of drinks with low, medium, and high alcohol content available on the Polish market and offered by various manufacturers, both Polish and foreign. Fluoride concentrations in individual samples were measured by potentiometric method with a fluoride ion-selective electrode. The highest fluoride levels were determined in the lowest percentage drinks (less than 10 % v/v ethanol), with the lowest fluoride levels observed in the highest percentage drinks (above 40 % v/v ethanol). In terms of types of alcoholic drinks, the highest fluoride levels were determined in beers and wines, while the lowest levels were observed in vodkas. These data confirm the fact that alcoholic beverages need to be considered as a significant source of fluoride delivered into the body. PMID:26475300

    2014-11-01

    The starting place for this essay is Knupfer and Room's insight that more restrictive norms around drinking and intoxication tend to be selectively applied to the economically dependent segments of society, such as women. However, since these authors wrote in 1964, women in the US and many other societies around the globe have experienced rising economic independence. The essay considers how the moral categories of acceptable drinking and drunkenness may have shifted alongside women's rising economic independence, and looks at evidence on the potential consequences for women's health and wellbeing. I argue that, as women have gained economic independence, changes in drinking norms have produced two different kinds of negative unintended consequences for women at high and low extremes of economic spectrum. As liberated women of the middle and upper classes have become more economically equal to men, they have enjoyed the right to drink with less restraint. For them, alongside the equal right to drink has come greater equality in exposure to alcohol-attributable harms, abuse and dependence. I further suggest that, as societies become more liberated, the economic dependency of low-income women is brought into greater question. Under such conditions, women in poverty-particularly those economically dependent on the state, such as welfare mothers-have become subject to more restrictive norms around drinking and intoxication, and more punitive social controls.

    The impact of heavy rainfall events on waterborne diarrheal diseases is uncertain. We conducted weekly, active surveillance for diarrhea in 19 villages in Ecuador from February 2004 to April 2007 in order to evaluate whether biophysical and social factors modify vulnerability to heavy rainfall events. A heavy rainfall event was defined as 24-hour rainfall exceeding the 90th percentile value (56 mm) in a given 7-day period within the study period. Mixed-effects Poisson regression was used to test the hypothesis that rainfall in the prior 8 weeks, water and sanitation conditions, and social cohesion modified the relationship between heavy rainfall events and diarrhea incidence. Heavy rainfall events were associated with increased diarrhea incidence following dry periods (incidence rate ratio = 1.39, 95% confidence interval: 1.03, 1.87) and decreased diarrhea incidence following wet periods (incidence rate ratio = 0.74, 95% confidence interval: 0.59, 0.92). Drinking water treatment reduced the deleterious impacts of heavy rainfall events following dry periods. Sanitation, hygiene, and social cohesion did not modify the relationship between heavy rainfall events and diarrhea. Heavy rainfall events appear to affect diarrhea incidence through contamination of drinking water, and they present the greatest health risks following periods of low rainfall. Interventions designed to increase drinking water treatment may reduce climate vulnerability. PMID:24256618

    Individuals who drink alcohol for the explicit motive of facilitating or enhancing sex may be more likely to engage in risky sexual behavior, including having sex under the influence of alcohol. However, efforts to assess sexual motives for drinking have been very limited to date. We examined the psychometric properties of a 5-item measure of sexual motives for drinking (SMD) in a sample of HIV-positive heavy drinking men who have sex with men. Findings provided excellent support for the scale's internal consistency and concurrent validity with a well-established measure of sexual alcohol expectancies (SAEs). Good discriminant validity was also established, as SMDs were correlated with other drinking motives but uniquely predicted the proportion of sex acts occurring under the influence of alcohol and other drugs, over-and-above other drinking motives and SAEs. SMDs were not significantly associated with unprotected anal intercourse. Adjusting for alcohol problem severity, higher SMDs were associated with lower willingness to consider changing drinking. Results suggest this measure of SMDs exhibits sound psychometric properties and may be useful in studies examining the association between alcohol use and sexual behavior. PMID:25134043

    Driving after drinking (DAD) is a serious public health concern found to be more common among college students than those of other age groups or same-aged non-college peers. The current study examined potential predictors of DAD among a dual-site sample of 3753 (65% female, 58% Caucasian) college students. Results showed that 19.1% of respondents had driven after 3 or more drinks and 8.6% had driven after 5 or more drinks in the past 3 months. A logistic regression model showed that male status, fraternity or sorority affiliation, family history of alcohol abuse, medium or heavy drinking (as compared to light drinking), more approving self-attitudes toward DAD, and alcohol expectancies for sexual enhancement and risk/aggression were independently associated with driving after drinking over and above covariates. These results extend the current understanding of this high risk drinking behavior in collegiate populations and provide implications for preventive strategies. Findings indicate that in addition to targeting at-risk subgroups, valuable directions for DAD-related interventions may include focusing on lowering both self-approval of DAD and alcohol-related expectancies, particularly those associated with risk/aggression and sexuality.

    This chapter reviews selected epidemiologic studies on drinking and associated problems among US ethnic minorities. Ethnic minorities and the White majority group exhibit important differences in alcohol use and related problems, including alcohol use disorders. Studies show a higher rate of binge drinking, drinking above guidelines, alcohol abuse, and dependence for major ethnic and racial groups, notably, Blacks, Hispanics, and American Indians/Alaskan Natives. Other problems with a higher prevalence in certain minority groups are, for example, cancer (Blacks), cirrhosis (Hispanics), fetal alcohol syndrome (Blacks and American Indians/Alaskan Natives), drinking and driving (Hispanics, American Indians/Alaskan Natives). There are also considerable differences in rates of drinking and problems within certain ethnic groups such as Hispanics, Asian Americans, and American Indians/Alaskan Natives. For instance, among Hispanics, Puerto Ricans and Mexican Americans drink more and have higher rates of disorders such as alcohol abuse and dependence than Cuban Americans. Disparities also affect the trajectory of heavy drinking and the course of alcohol dependence among minorities. Theoretic accounts of these disparities generally attribute them to the historic experience of discrimination and to minority socioeconomic disadvantages at individual and environmental levels.

    Research suggests that high school athletes are at greater risk for heavy alcohol use and alcohol-related problems than their non-athlete peers. Drinking motives unique to the athletic experience may contribute to elevated use. The Athlete Drinking Scale (ADS) was designed to assess sport-related motives for alcohol use, but has not yet been validated among high school athletes. The purpose of this study was to examine the psychometric properties of the ADS among a sample of high school athletes. Participants were 216 high school student-athlete drinkers who completed anonymous self-report surveys. A confirmatory factor analysis resulted in a revised three-factor solution with a satisfactory overall model fit. Path analyses indicated that the Positive Reinforcement motives subscale was the only ADS subscale that was significantly associated with alcohol use and alcohol-related problems when controlling for the effects of the other factors (i.e., age and gender) in this population. The ADS may be a valuable assessment tool for researchers and clinicians involved in alcohol prevention efforts for high school athletes. PMID:27082264

    Background This study examined alcohol use patterns among men and women with depression seeking outpatient psychiatric treatment, including factors associated with recent heavy episodic drinking and motivation to reduce alcohol consumption. Methods The sample consisted of 1183 patients ages 18 and over who completed a self-administered, computerized intake questionnaire and who scored ≥ 10 on the Beck Depression Inventory-II (BDI-II). Additional measures included current and past alcohol questions based on the Addiction Severity Index, heavy episodic drinking (≥ 5 drinks on one or more occasions in the past year), alcohol-related problems on the Short Michigan Alcoholism Screening Test (SMAST), and motivation to reduce drinking using the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES). Results Among those who consumed any alcohol in the past year (73.9% of the sample), heavy episodic drinking in the past year was reported by 47.5% of men and 32.5% of women. In logistic regression, prior-year heavy episodic drinking was associated with younger age (p=.011), male gender (p=.001) and cigarette smoking (p=.002). Among patients reporting heavy episodic drinking, motivation to reduce alcohol consumption was associated with older age (p=.008), greater usual quantity of alcohol consumed (p<.001), and higher SMAST score (p<.001). Conclusions In contrast to prior clinical studies, we examined sub-diagnostic alcohol use and related problems among psychiatric outpatients with depression. Patients reporting greater drinking quantities and alcohol-related problems also express more motivation to reduce drinking, providing intervention opportunities for mental health providers that should not be overlooked.

    2014-10-01

    This study examined the joint effects of contextual cues and alcohol intoxication on the associations between activation of positive and negative alcohol expectancies in memory and self-reported urges to drink alcohol after a laboratory alcohol administration. Young adult heavy drinkers were randomly assigned to drink a moderate dose of alcohol or a placebo (alcohol manipulation), and then listened to positive or negative drinking scenarios (cue manipulation). Before and after these manipulations, participants completed an alcohol expectancy Stroop task assessing positive and negative expectancy activation, as well as self-report measures of urges to drink. Regression analyses revealed that the alcohol and cue manipulations had a joint, moderating impact on the associations between expectancy activation and postcue changes in urge to drink. Specifically, both increased activation of negative expectancies and decreased activation of positive expectancies predicted decreases in urges to drink, but only for intoxicated participants in the negative cue condition. There were no associations between expectancy activation and urges to drink for those in the positive cue condition regardless of beverage condition. Results suggest that whether memory activation of alcohol expectancies has an impact on urge to drink after alcohol is on board may depend on the relevance of the activated expectancies to the current drinking context. This process appears to be influenced by a complex interaction between contextual cues in the environment and the pharmacological effects of alcohol. PMID:25111186

    Racial and ethnic disparities in alcohol use and alcohol-related problems have been well-documented. Less information is available about possible disparities in outcomes related to mental health services utilization. The differential effect of mental health services use by race on drinking outcomes was examined. Wave 2 of a national population sample of employed adults who reported having at least one alcoholic drink in the past year (n=1058) encompassed measures of the prevalence of mental health services use in response to stress, and alcohol-related outcomes. Nonwhite participants who reported using any mental health services, 4 or more mental health visits in the past year, and 8 or more mental health visits in the past year reported lower rates of problematic drinking behaviors, including frequency of drinking to intoxication, heavy episodic drinking, and modified Brief MAST scores, than whites who reported similar use of mental health services.

    Alcohol-related expectancies have been shown to correlate with and predict a wide range of drinking behaviors. Rotter's social learning theory asserts that behavioral prediction can be improved through the use of reinforcement value in addition to expectancies. The present investigation evaluated this assertion in comparing the ability of alcohol-related expectancies to predict alcohol consumption for low and high assertive college students. It was hypothesized that the expectation that alcohol would facilitate social assertion would be predictive of self-reported heavy drinking by low, but not highly assertive students. Results showed that the typical quantity, maximum quantity, and frequency of drinking by low assertive females were predicted only by the expectation of Social Assertion. For low assertive males, Social Assertion was predictive of frequency of drinking. Moreover, of the students, male and female, high in assertiveness, drinking patterns were not predicted by the expectation of enhanced Social Assertion.

    Pre-gaming, the practice of consuming alcohol before attending a social function, has not received as much research attention as drinking games among college students. This study investigated the prevalence of both pre-gaming and drinking game participation in a sample of mandated students (N = 334) who had been referred for an alcohol violation. Approximately one-third (31%) of the sample reported pre-gaming on the night of their referral event. Pre-gaming was associated with higher estimated blood alcohol content on that night, along with a greater history of pre-gaming and taking greater responsibility for the incident. A higher proportion of the students (48.7%) reported playing drinking games on the event night and reported the event to be less aversive than non-players. Neither drinking games nor pre-gaming was consistently related to recent alcohol consumption or problems, nor did they frequently occur together on the event night. Pre-gaming was a unique predictor of intoxication on the night of the referral, and drinking games were not. Therefore, pre-gaming and drinking games appear to be distinct activities. This research suggests methods of prevention for both activities as well as promising research directions for future research. PMID:17574344

    Background While the utility of experimental free-access alcohol self-administration paradigms is well-established, little data exist addressing the question of whether study participation influences subsequent natural alcohol consumption. We here present drinking reports of young adults before and after participation in intravenous alcohol self-administration studies. Methods Timeline Follow-back (TLFB) drinking reports for the 6 weeks immediately preceding the first, and the 6 weeks after the last experimental alcohol challenge were examined from subjects completing one of two similar alcohol self-administration paradigms. In study 1, eighteen social drinkers (9 females, mean age 24.1 years) participated in 3 alcohol self-infusion sessions up to a maximum blood alcohol concentration (BAC) of 160 mg%. Study 2 involved 60 participants (30 females, mean age 18.3 years) of the Dresden Longitudinal Study on Alcohol Use in Young Adults (D-LAYA), who participated in 2 sessions of alcohol self-infusion up to a maximum BAC of 120 mg%, and a non-exposed age- matched control group of 42 (28 females, mean age 18.4 years) subjects. Results In study 1, participants reported (3.7%) fewer heavy drinking days as well as a decrease of 2.5 drinks per drinking day after study participation compared to pre-study levels (p<.05 respectively).. In study 2, alcohol-exposed participants reported 7.1% and non- alcohol-exposed controls 6.5% fewer drinking days at post-study measurement (p<.001), while percent heavy drinking days and drinks per drinking day did not differ. Conclusion These data suggest that participation in intravenous alcohol self-administration experiments does not increase subsequent real-life drinking of young adults. PMID:25903217

    College student alcohol consumption is a major concern, and is known to increase during the celebration of special events. This study examined a student-constructed holiday, State Patty’s Day, at a university with a dominant drinking culture using three sources of data – coded data from Facebook groups, daily web surveys from first-year students (N= 227, 51% male, age 18 to 20; 27.3% Hispanic/Latino; of non-Hispanic/Latino, 26.9% of sample European American/White, 19.4% Asian American/Hawaiian/Pacific Islander, 15.9% African American/Black, 10.6% more than one race), and criminal offense data from police records. Results indicated that messages about State Patty’s Day on Facebook focused on drinking and social aspects of the holiday, such as the social context of drinking, a sense of belonging to a larger community, and the social norms of drinking. These messages were rarely about consequences and rarely negative. On State Patty’s Day, 51% of students consumed alcohol, compared to 29% across other sampled weekend days. Students consumed more drinks (M = 8.2 [SD = 5.3] drinks per State Patty’s Day drinker) and were more likely to engage in heavy drinking on State Patty’s Day, after controlling for gender, drinking motives, and weekend, demonstrating the event-specific spike in heavy drinking associated with this holiday. The impact of this student-constructed holiday went beyond individual drinking behavior; alcohol-specific and other crime also peaked on State Patty’s Day and the day after. Event-specific prevention strategies may be particularly important in addressing these spontaneous, quickly-constructed, and dynamic events. PMID:22685369

  6. Unintended consequences of cigarette price changes for alcohol drinking behaviors across age groups: evidence from pooled cross sections

    PubMed Central

    2012-01-01

    Background Raising prices through taxation on tobacco and alcohol products is a common strategy to raise revenues and reduce consumption. However, taxation policies are product specific, focusing either on alcohol or tobacco products. Several studies document interactions between the price of cigarettes and general alcohol use and it is important to know whether increased cigarette prices are associated with varying alcohol drinking patterns among different population groups. To inform policymaking, this study investigates the association of state cigarette prices with smoking, and current, binge, and heavy drinking by age group. Methods The 2001-2006 Behavioral Risk Factor Surveillance System surveys (n = 1,323,758) were pooled and analyzed using multiple regression equations to estimate changes in smoking and drinking pattern response to an increase in cigarette price, among adults aged 18 and older. For each outcome, a multiple linear probability model was estimated which incorporated terms interacting state cigarette price with age group. State and year fixed effects were included to control for potential unobserved state-level characteristics that might influence smoking and drinking. Results Increases in state cigarette prices were associated with increases in current drinking among persons aged 65 and older, and binge and heavy drinking among persons aged 21-29. Reductions in smoking were found among persons aged 30-64, drinking among those aged 18-20, and binge drinking among those aged 65 and older. Conclusions Increases in state cigarette prices may increase or decrease smoking and harmful drinking behaviors differentially by age. Adults aged 21-29 and 65 and older are more prone to increased drinking as a result of increased cigarette prices. Researchers, practitioners, advocates, and policymakers should work together to understand and prepare for these unintended consequences of tobacco taxation policy. PMID:22784412

    Background College drinking has become a significant health issue in China; the current study addressed the gap that no prior research has investigated drinking motives among Chinese undergraduate students. Objectives This study aimed to replicate the four-factor structure of the Drinking Motives Questionnaire-Revised (DMQ-R) reported for Western populations. Additionally, the relationships between drinking motives and alcohol use were investigated. Methods In 2012, 436 participants (mean age = 20.49 and SD = 1.49; 50% male) recruited from a college in China completed a self-administered survey in their classroom setting. Drinking motives were measured by the Chinese version of the DMQ-R; three indicators of alcohol use were assessed. Factor analysis was conducted to examine the factor structure of the DMQ-R, followed by regression analysis to investigate the associations between drinking motives and alcohol-related outcomes. Results Confirmatory factor analysis failed to replicate the measurement model tested, but exploratory factor analysis identified a similar four-dimensional factor structure. Reliability and convergent and discriminant validity of the four factors were acceptable. The results also showed that social motives were related to alcohol use and heavy drinking; conformity motives were related to alcohol use and alcohol-related problems. Enhancement motives were the strongest correlates of alcohol use; coping motives were the strongest correlates of heavy drinking and alcohol-related problems. Conclusions/Importance The DMQ-R was a reliable and valid scale measuring four types of drinking motives among Chinese college students. Findings suggested that the motivational model of alcohol use may apply to studying college drinking in China. PMID:26576670

    Objective We identify drinking styles that place teens at greatest risk of later alcohol use disorders (AUD). Design Population-based cohort study. Setting Victoria, Australia. Participants A representative sample of 1943 adolescents living in Victoria in 1992. Outcome measures Teen drinking was assessed at 6 monthly intervals (5 waves) between mean ages 14.9 and 17.4 years and summarised across waves as none, one, or two or more waves of: (1) frequent drinking (3+ days in the past week), (2) loss of control over drinking (difficulty stopping, amnesia), (3) binge drinking (5+ standard drinks in a day) and (4) heavy binge drinking (20+ and 11+ standard drinks in a day for males and females, respectively). Young Adult Alcohol Use Disorder (AUD) was assessed at 3 yearly intervals (3 waves) across the 20s (mean ages 20.7 through 29.1 years). Results We show that patterns of teen drinking characterised by loss of control increase risk for AUD across young adulthood: loss of control over drinking (one wave OR 1.4, 95% CI 1.1 to 1.8; two or more waves OR 1.9, CI 1.4 to 2.7); binge drinking (one wave OR 1.7, CI 1.3 to 2.3; two or more waves OR 2.0, CI 1.5 to 2.6), and heavy binge drinking (one wave OR 2.0, CI 1.4 to 2.8; two or more waves OR 2.3, CI 1.6 to 3.4). This is not so for frequent drinking, which was unrelated to later AUD. Although drinking was more common in males, there was no evidence of sex differences in risk relationships. Conclusions Our results extend previous work by showing that patterns of drinking that represent loss of control over alcohol consumption (however expressed) are important targets for intervention. In addition to current policies that may reduce overall consumption, emphasising prevention of more extreme teenage bouts of alcohol consumption appears warranted. PMID:26868948

    Basic behavioral and neurobiological research has demonstrated that deficiencies in naturally occurring substance-free rewards are both a cause and a consequence of substance abuse that are due in part to the systematic discounting of delayed substance-free rewards. Existing brief motivational interventions (BMIs) for alcohol abuse do not target this mechanism of change. The goal of this uncontrolled pilot study was to evaluate a behavioral economic Substance-Free Activity Session (SFAS) to traditional alcohol BMIs. Participants were 13 college freshmen who reported two or more heavy drinking episodes (>5/4 drinks in an occasion for men/ women) in the past month. All participants completed a baseline assessment and a BMI that addressed alcohol use. In addition, participants received the SFAS, a 50-min individual session that attempts to increase engagement in constructive alternatives to drinking by enhancing the salience of delayed rewards (academic and career success) and the patterns of behavior (academic and extracurricular engagement) leading to these outcomes. At the 1-month follow-up assessment, participants reported significant reductions in heavy drinking, and moderate to large effect size reductions in weekly drinking and peak blood alcohol levels. The results of this pilot study provide preliminary support for the efficacy of this behavioral economic intervention session as a supplement to traditional alcohol BMIs. PMID:24039620

    Developing discrepancy between one's values and behaviors is theoretically important in motivating change; however, existing studies lack a validated measure of value-behavior discrepancy for alcohol misuse. The current studies aimed to modify Wilson & DuFrene (2008) Valued Living Questionnaire (VLQ) to assess consistency of alcohol use with important values. In Study 1, the initial factor structure and test-retest reliability of the VLQ for Alcohol Use (VLQ-A) was tested in a sample of college students who regularly drink alcohol (N = 150). Results guided modifications to the measure. In Study 2, the revised measure's factor structure and predictive validity were tested with a second sample of college students who drink alcohol (N = 222). In both studies, exploratory factor analysis supported a unidimensional factor structure. Perceived discrepancy between alcohol use and important values predicted greater readiness to change, while perceived consistency between alcohol use and important values predicted more frequent heavy episodic drinking. Certain values were more useful in predicting outcomes than others. Alcohol use (heavy vs. moderate drinking) did not moderate outcomes. The VLQ-A is a brief and reliable self-report measure of perceived discrepancy between drinking behaviors and important values that may increase readiness to change. Future research examining the generalizability of findings to various samples and the efficacy of the VLQ-A as a supplement to brief interventions is warranted.

    Objective Determine the efficacy of three brief intervention strategies that address heavy drinking among injured patients. Summary of Background Data The content or structure of brief interventions most effective at reducing alcohol misuse following traumatic injury is not known. Methods Injured patients from three trauma centers were screened for heavy drinking and randomly assigned to brief advice or BA (n=200), brief motivational intervention or BMI (n=203), or brief motivational intervention plus a telephone booster using personalized feedback or BMI+B (n=193). Among those randomly assigned, 57% met criteria for moderate to severe alcohol problems. The primary drinking outcomes were assessed at 3, 6, and 12 months. Results Compared with BA and BMI, BMI+B showed significant reductions in the number of standard drinks consumed per week at 3 (Δ adjusted means=-1.22, 95% C.I.=-.99 ∼ -1.49, p=.01) and 6 months (Δ adjusted means=-1.42, 95% C.I.=-1.14 ∼ -1.76, p=.02), percent days of heavy drinking at 6 months (Δ adjusted means=-5.90, 95% C.I.=-11.40 ∼ -0.40, p=.04), maximum number of standard drinks consumed in one day at 3 (Δ adjusted means=-1.38, 95% C.I.=-1.18 ∼ -1.62, p=.003) and 12 months (Δ adjusted means=-1.71, 95% C.I.=-1.47 ∼ -1.99, p=.02), and number of standard drinks consumed per drinking day at 3 (Δ adjusted means=-1.49, 95% C.I.=-1.35∼-1.65, p=.002) and 6 months (Δ adjusted means=-1.28,, 95% C.I.=-1.17 ∼ -1.40, p=.01). Conclusion Brief interventions based on motivational interviewing with a telephone booster using personalized feedback were most effective at achieving reductions in alcohol intake across the three trauma centers.

    Heavy-metal pollution occurs in various environments, including water, air and soil, and has serious effects on human health. Since heavy-metal pollution in drinking water causes various diseases including skin cancer, it has become a global problem worldwide. However, there is limited information on the mechanism of development of heavy-metal-mediated disease. We performed both fieldwork and experimental studies to elucidate the levels of heavy-metal pollution and mechanisms of development of heavy-metal-related disease and to develop a novel remediation system. Our fieldwork in Bangladesh, Vietnam and Malaysia demonstrated that drinking well water in these countries was polluted with high concentrations of several heavy metals including arsenic, barium, iron and manganese. Our experimental studies based on the data from our fieldwork demonstrated that these heavy metals caused skin cancer and hearing loss. Further experimental studies resulted in the development of a novel remediation system with which toxic heavy metals were absorbed from polluted drinking water. Implementation of both fieldwork and experimental studies is important for prediction, prevention and therapy of heavy-metal-mediated diseases.

  15. Portable Nanomesh Creates Safer Drinking Water

    Providing astronauts with clean water is essential to space exploration to ensure the health and well-being of crewmembers away from Earth. For the sake of efficient and safe long-term space travel, NASA constantly seeks to improve the process of filtering and re-using wastewater in closed-loop systems. Because it would be impractical for astronauts to bring months (or years) worth of water with them, reducing the weight and space taken by water storage through recycling and filtering as much water as possible is crucial. Closed-loop systems using nanotechnology allow wastewater to be cleaned and reused while keeping to a minimum the amount of drinking water carried on missions. Current high-speed filtration methods usually require electricity, and methods without electricity usually prove impractical or slow. Known for their superior strength and electrical conductivity, carbon nanotubes measure only a few nanometers in diameter; a nanometer is one billionth of a meter, or roughly one hundred-thousandth the width of a human hair. Nanotubes have improved water filtration by eliminating the need for chemical treatments, significant pressure, and heavy water tanks, which makes the new technology especially appealing for applications where small, efficient, lightweight materials are required, whether on Earth or in space. "NASA will need small volume, effective water purification systems for future long-duration space flight," said Johnson Space Center s Karen Pickering. NASA advances in water filtration with nanotechnology are now also protecting human health in the most remote areas of Earth.

    The purpose of this study was to evaluate alcohol consumption among adolescents from Tucuman, Argentina, and to determine its possible relationship with increased levels of blood pressure. Three hundred fifty-six students aged 13-18 included in the study were asked to answer questionnaires anonymously. Two blood pressures measures were then taken. Differences between both sexes were found in quantity and frequency of alcohol consumption. Enjoyment was determined to be the main reason for drinking. There was an association between frequency and alcohol-related problems, and smoking habits. There were also differences in blood pressure among males and females. A weak, but significant, relationship between quantity/frequency index and diastolic blood pressure was found. A greater prevalence of hypertension in male heavy drinkers was noted as well. Because this addiction implies multiple social problems and it also accounts for a hypertension risk factor, the importance of aiming at developing prevention strategies for alcohol abuse among adolescents is stressed.

    Hazardous drinking is prevalent among persons living with HIV/AIDS (PLWHA). Anxiety sensitivity is a vulnerability factor that is highly associated with hazardous drinking among seronegatives, but has yet to be tested in PLWHA. Additionally, there is a need to examine potential mechanisms underlying associations of anxiety sensitivity and hazardous drinking. Emotion dysregulation is one potential construct that may explain the association between anxiety sensitivity and hazardous drinking. The current study examined emotion dysregulation as a potential explanatory variable between anxiety sensitivity and four, clinically significant alcohol-related outcomes among PLWHA: hazardous drinking, symptoms of alcohol dependence, number of days consuming alcohol within the past month, and degree of past heavy episodic drinking. The sample included 126 PLWHA (Mage=48.3; SD=7.5; 65.9% male). Results indicated significant indirect effects of anxiety sensitivity via emotion dysregulation in all models. Indirect effects (κ(2)) were of medium effect size. Alternative models were run reversing the predictor with mediator and, separately, reversing the mediator with the proposed outcome(s); alternative models yielded non-significant indirect effects in all but one case. Together, the current results indicate that anxiety sensitivity is associated emotion dysregulation, which, in turn, is associated with hazardous drinking outcomes. Overall, these findings may provide initial empirical evidence that emotion dysregulation may be a clinical intervention target for hazardous drinking.

    Individuals who drink alcohol for the explicit motive of facilitating or enhancing sex may be more likely to engage in risky sexual behavior, including having sex under the influence of alcohol. However, efforts to assess sexual motives for drinking (SMDs) have been very limited to date. We examined the psychometric properties of a 5-item measure of SMDs in a sample of HIV-positive heavy drinking men who have sex with men. Findings provided excellent support for the scale's internal consistency and concurrent validity with a well-established measure of sexual alcohol expectancies (SAEs). Good discriminant validity was also established, as SMDs were correlated with other drinking motives but uniquely predicted the proportion of sex acts occurring under the influence of alcohol and other drugs, over and above other drinking motives and SAEs. SMDs were not significantly associated with unprotected anal intercourse. Adjusting for alcohol problem severity, higher SMDs were associated with lower willingness to consider changing drinking. Results suggest this measure of SMDs exhibits sound psychometric properties and may be useful in studies examining the association between alcohol use and sexual behavior. (PsycINFO Database Record

    Among the most widely predicted and accepted consequences of global climate change are increases in both the frequency and severity of a variety of extreme weather events. Such weather events include heavy rainfall and floods, cyclones, droughts, heatwaves, extreme cold, and wildfires, each of which can potentially impact drinking water quality by affecting water catchments, storage reservoirs, the performance of water treatment processes or the integrity of distribution systems. Drinking water guidelines, such as the Australian Drinking Water Guidelines and the World Health Organization Guidelines for Drinking-water Quality, provide guidance for the safe management of drinking water. These documents present principles and strategies for managing risks that may be posed to drinking water quality. While these principles and strategies are applicable to all types of water quality risks, very little specific attention has been paid to the management of extreme weather events. We present a review of recent literature on water quality impacts of extreme weather events and consider practical opportunities for improved guidance for water managers. We conclude that there is a case for an enhanced focus on the management of water quality impacts from extreme weather events in future revisions of water quality guidance documents. PMID:26311274

    This paper analyses driving under the influence of alcohol and drugs (DUI) from a governmentality perspective. The paper is based on qualitative interviews with 25 persons, convicted of drink-driving and at the time of the interviews participating in Alcohol/Traffic courses in Denmark (mandatory courses for DUI-convicted people). Four drink-driver profiles are identified: regular heavy drinkers who regard themselves as addicted; regular drinkers who claim they are in control of both their alcohol use and their drink-driving; occasional multi-substance users who associate their DUI with strong feelings of control loss; and occasional drinkers or drug users with limited experience of drink-driving. The paper analyses drink-driving as a form of "failed self-governance" and shows how some of the convicted drink-drivers negotiate guilt and blame by either justifying their DUI (they were "in full control" and hence did not risk other people's lives) or excusing it (they had "lost control" over their alcohol and/or drug intake and therefore did not engage in DUI of their own free will).

    The literature suggests that identity impairments play a role in certain forms of maladaptive behavior. Thus, this study was designed to evaluate the extent to which a "Partier" self-concept confers risk for adverse drinking-related consequences, mediating the well documented relationship between college student binge drinking and adverse outcomes. Participants completed an Internet survey examining binge drinking behaviors and related consequences, "Partier" self-concept, and demographic characteristics. This sample was comprised of 251 undergraduate psychology students (M(age)=19.90, SD(age)=1.80; 83% female). Results suggest that "Partier" self-concept partially mediates the relationship between binge drinking and adverse consequences, and it contributes unique variance beyond that explained by frequency of binge drinking and duration of alcohol consumed during binge episodes. Future research should explore whether, for undergraduate college students, binge drinking prevention efforts tailored towards self-concept may fare better than those that have traditionally focused on heavy alcohol use, negative consequences, and related sanctions.

    Daily data collected over 14 consecutive days were used to examine whether extreme drinking was more likely on days college students reported prepartying (i.e., drinking before going out) or playing drinking games in a multi-ethnic sample of college seniors (analysis subsample: N=399; 57% women; M age=21.48 years, SD=.40). Multilevel modeling with drinking occasions at Level 1 (1265 drinking days) nested within persons at Level 2 (399 drinkers) were used to predict four extreme drinking behavior outcomes at the daily level: consuming at least 8/10 (women/men) drinks, reaching an estimated blood alcohol concentration (eBAC) of .16% or greater, drinking enough to stumble, and drinking enough to pass out. Prepartying only (29% of drinking days) was more common than playing drinking games only (10%) or engaging in both behaviors on the same day (13%). Odds of extreme drinking were greater among students who frequently engaged in prepartying (ORs: 1.86-2.58) and drinking games (ORs: 1.95-4.16), except prepartying frequency did not predict drinking enough to pass out. On days students prepartied (ORs: 1.58-2.02) and on days they played drinking games (ORs: 1.68-1.78), odds of extreme drinking were elevated, except drinking games did not predict eBAC of .16% or greater. Extreme drinking is attributable to both person-level characteristics (e.g., preparty frequency) and specific drinking behaviors on a given day. Prepartying and drinking games confer elevated risk of extreme drinking and are important targets in alcohol interventions for college seniors. PMID:25437263

    As little research has examined factors influencing increased and heavy drinking behavior among American sojourners abroad, this study was designed to examine how acculturation orientations (i.e., separation versus assimilation), host country per capita drinking rates, and perceptions about the drinking behavior among other sojourners and natives in the host country predicted alcohol risk abroad. A sample of 216 American college students completing study abroad programs completed a pre-abroad questionnaire to document their pre-abroad drinking levels, followed by a post-return questionnaire to assess drinking while abroad, acculturation orientations and perceived norms of drinking behavior within the foreign environment. A dichotomous variable was created to compare United States (U.S.) per capita drinking rates with those of the host country. Hierarchical repeated-measures ANOVAs examined the changes in drinking from pre-abroad to abroad levels. Participants studying in countries with higher drinking rates than the U.S. and those with higher perceptions about the drinking behavior in the country increased their drinking to a greater extent. Those with higher separation acculturation orientations and greater perceptions drank at heavier levels while abroad. Participants with a greater assimilation orientation and higher perceptions about native drinking, as well as those with a greater separation orientation and higher perceptions about other students' alcohol use drank the heaviest while abroad. These findings have implications for future preventive work with American students and other sojourning groups to promote pre-abroad knowledge of more accurate drinking norms and greater engagement in the culture to potentially prevent increased and heavier drinking.

    The results of this paper are an initiation to capture the drinking water and/or groundwater elemental situation in the youngest European country, Kosovo. We aim to present a clear picture of the natural uranium concentration in drinking water and/or groundwater as it is distributed to the population of Kosovo. Nine hundred and fifty-one (951) drinking water samples were analyzed by inductively coupled plasma mass spectrometry (ICPMS). The results are the first countrywide interpretation of the uranium concentration in drinking water and/or groundwater, directly following the Kosovo war of 1999. More than 98% of the samples had uranium concentrations above 0.01 μg L(-1), which was also our limit of quantification. Concentrations up to 166 μg L(-1) were found with a mean of 5 μg L(-1) and median 1.6 μg L(-1) were found. Two point six percent (2.6%) of the analyzed samples exceeded the World Health Organization maximum acceptable concentration of 30 μg L(-1), and 44.2% of the samples exceeded the 2 μg L(-1) German maximum acceptable concentrations recommended for infant food preparations.

    Caffeine-containing energy drinks have emerged as a public health concern due to their association with caffeine toxicity and alcohol use. Despite the fact that previous research has linked caffeine use in the form of coffee drinking to smoking, there is little research examining the association between energy drinks and smoking. The present study examines demographic and behavioral factors associated with energy drink use among a sample of rural Ohio Appalachian smokers. It was hypothesized that male gender, young age (21-30 years.) and alcohol use would be associated with energy drink use. A sample of adult smokers (n = 298) from Ohio Appalachian counties were interviewed regarding demographic and behavioral factors. Logistic regression analysis was used to assess the association between these factors and energy drink use. Seventy percent of Ohio Appalachian smokers studied had ever used an energy drink and 40 % had used an energy drink in the past month. Young age, male gender, and single marital status were associated with higher odds of ever having used an energy drink. Young age, and binge drinking were associated with higher odds of past 30-day use while abstinence from drinking was associated with lower odds of past 30-day use. Ohio Appalachian adult smokers had higher rates of energy drink use compared to previous estimates of ever or past month use found in other studies. The combined use of caffeine, nicotine, and alcohol warrants attention due to potential for health risk.

    The quantity, frequency, and variability of alcohol and other substance use is described in a random sample of 1,436 enrolled members of four tribes from the northern United States. Overall, males begin regular drinking at an earlier age than do females (17 vs. 18.1 years), and more males drink alcohol than females (70.7% to 60.4%). There are some very heavy drinkers who drink daily in these populations, but most drinkers are binge drinkers. On any typical day abstinence from alcohol is the modal pattern. That is, most respondents indicated very infrequent drinking, and among the older age groups (40+), there is a high rate of abstinence. Males drink more frequently and in larger quantities than females. The number of drinking days per month is 4.7 for males and 2.1 for females, and on those days when drinking occurs, the males consume an average of 5.7 drinks and females an average of 3.1. The highest prevalence of drinking and the heaviest drinking occur among those who are under the age of 30. With the exception of tobacco use, which is high in all age categories, the use of other drugs is highest in those under 30. PMID:11698981

    Topiramate, which interacts with multiple neurotransmitter and enzyme systems, is approved by the Food and Drug Administration to treat seizure disorder, prevent migraine, and (in combination with phentermine) reduce weight. Topiramate has also been shown in multiple studies to reduce heavy drinking. We found that topiramate 200 mg/day significantly reduced heavy drinking in heavy drinkers with a treatment goal of reduced drinking (Kranzler et al. 2014). Further, in the European American (EA) subsample (n=122), a single nucleotide polymorphism (rs2832407) in GRIK1, which encodes the GluK1 subunit of the kainate receptor, moderated the effect on heavy drinking days. Here we examined the effects of topiramate on body-mass index (BMI) and the moderating effect of rs2832407 in the EA subsample from Kranzler et al. (2014). Across the 12 weeks of treatment, BMI was reduced by 1.2 kg/m2 (p<0.001) in the topiramate group, but was unchanged in the placebo group. There was no evidence of moderation by rs2832407 of topiramate’s effects on BMI. Controlling for changes in drinking and other potential confounders did not alter the findings. These results suggest that the effect of topiramate on drinking behavior, in which the GluK1-containing kainate receptor appears to play a key role, can be dissociated from its effect on weight, the specific mechanism of which remains to be determined. www.clinicaltrials.gov registration: NCT00626925 PMID:24978347

  10. Hazards of heavy metal contamination.

    PubMed

    Järup, Lars

    2003-01-01

    The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. These metals have been extensively studied and their effects on human health regularly reviewed by international bodies such as the WHO. Heavy metals have been used by humans for thousands of years. Although several adverse health effects of heavy metals have been known for a long time, exposure to heavy metals continues, and is even increasing in some parts of the world, in particular in less developed countries, though emissions have declined in most developed countries over the last 100 years. Cadmium compounds are currently mainly used in re-chargeable nickel-cadmium batteries. Cadmium emissions have increased dramatically during the 20th century, one reason being that cadmium-containing products are rarely re-cycled, but often dumped together with household waste. Cigarette smoking is a major source of cadmium exposure. In non-smokers, food is the most important source of cadmium exposure. Recent data indicate that adverse health effects of cadmium exposure may occur at lower exposure levels than previously anticipated, primarily in the form of kidney damage but possibly also bone effects and fractures. Many individuals in Europe already exceed these exposure levels and the margin is very narrow for large groups. Therefore, measures should be taken to reduce cadmium exposure in the general population in order to minimize the risk of adverse health effects. The general population is primarily exposed to mercury via food, fish being a major source of methyl mercury exposure, and dental amalgam. The general population does not face a significant health risk from methyl mercury, although certain groups with high fish consumption may attain blood levels associated with a low risk of neurological damage to adults. Since there is a risk to the fetus in particular, pregnant women should avoid a high intake of certain fish, such as shark, swordfish and

    Zhang, Hui

    2004-05-01

    In the Hetao region in northern China drinking water has become toxic due to the presence of arsenic (As) and other heavy metals in soil and water. The 7 counties in this region cover approx. 6100 km2, and in all 180,000 people are suffering from the toxic effects of contaminated drinking water. However, very few studies have been carried out in the region on the possible source of this arsenic. This paper is based on studies of the distribution of heavy metals in soil and groundwater. Results show that the average content of As is 0.483 microg g(-1) in groundwater and 13.74 microg g(-1) in soil. These levels are higher than the drinking water standard of 0.05 microg g(-1) recommended by the World Health Organization in 1984, and for the local background level in soil (5.20 microg g(-1)). This heavy-metal content in water and soil decreases gradually with increasing distance from the contaminated area, which fronts the Yin Mountains. The ratios of the Pb and Sr isotope contents in water are closely related to the ratios found in the water of the regions' mining area, and the ratios in soil correspond to the content of As in groundwater and soil in the area where pathological changes have been detected. Results suggest that the contaminants originate in the ore deposit zone fronting Yin mountains in the upper reaches of the Hetao Region.

    2014-01-01

    The current study describes the relative predictive power of descriptive norms (i.e., how much the target student believes referents “drink until they get drunk”) and reflective injunctive norms (i.e., target student’s perception of referents’ approval of the target student drinking until drunk) across various reference groups. The aim of this study was to gain further insight into which types of norms and reference groups are most highly concurrently correlated with risky drinking. It was hypothesized that both reflective injunctive and descriptive norms would be significantly positively correlated with risky drinking outcomes, and that more proximal reference group norms would be more highly predictive than more distal reference group norms. Participants (N = 837) were college students on the US west coast who completed questionnaires in the context of a longitudinal parent study. Cross-sectional, zero-inflated negative binomial regressions were used to test the relative strengths of correlations between descriptive and reflective injunctive norms (i.e., for typical college students, closest friend, person whose opinion they value most and closest family member) and risky drinking (i.e., peak alcohol quantity, frequency of heavy drinking episodes, and alcohol-related problems). Findings showed that descriptive and reflective injunctive norms were most consistently, strongly and positively correlated with risky drinking when they involved referents who were closer to the target college drinkers (i.e., closest friend and person whose opinion you value the most). Norms for typical college students were less consistent correlates of risky drinking. These findings may contribute to the knowledge base for enhancing normative re-education and personalized normative feedback interventions to include more personally salient and powerful normative information.

    The aim of this population-based study was to investigate differences in dietary patterns in relation to the level of alcohol consumption among Finnish adults. This study was part of the FinDrink project, an epidemiologic study on alcohol use among Finnish population. It utilized data from the Kuopio Ischaemic Heart Disease Risk Factor Study. A total of 1720 subjects comprising of 816 men and 904 women aged 53–73 years were included in the study in 1998–2001. Food intake was collected via a 4-day food diary method. Self-reported alcohol consumption was assessed with quantity-frequency method based on the Nordic Alcohol Consumption Inventory. Weekly alcohol consumption was categorized into three groups: non-drinkers (<12 grams), moderate drinkers (12–167.9 grams for men, 12–83.9 grams for women) and heavy drinkers (≥168 grams for men, ≥84 grams for women). Data were analyzed for men and women separately using multiple linear regression models, adjusted for age, occupational status, marital status, smoking, body mass index and leisure time physical activity. In women, moderate/heavy drinkers had lower fibre intake and moderate drinkers had higher vitamin D intake than non-drinkers. Male heavy drinkers had lower fibre, retinol, calcium and iron intake, and moderate/heavy drinkers had higher vitamin D intake than non-drinkers. Fish intake was higher among women moderate drinkers and men moderate/heavy drinkers than non-drinkers. In men, moderate drinkers had lower fruit intake and heavy drinkers had lower milk intake than non-drinkers. Moderate drinkers had higher energy intake from total fats and monosaturated fatty acids than non-drinkers. In contrast, energy intake from carbohydrates was lower among moderate/heavy drinkers than non-drinkers. In conclusion, especially male heavy drinkers had less favorable nutritional intake than moderate and non-drinkers. Further studies on the relationship between alcohol consumption and dietary habits are needed to

    Parental influences on youth drinking are well documented but not the influence of extended family members. This article explores extended family influences on alcohol use among Mexican youths and whether extended family members can be considered natural mentors. We conducted a qualitative study using ethnographic open ended interviews with 117 first year university students in Mexico City. The ethnographic interviews revealed six drinking groups: excessive, heavy, regular, occasional, abstainers and non drinkers. Youths reported close relationships with extended family members who provided counsel and acted as representatives of familial norms and values. The alcohol beliefs and behaviors of these family members, including their alcohol misuse, had a positive influence on youths’ alcohol attitudes. The naturally occurring mentoring relationships of Mexican extended family members can positively influence moderate youth drinking. Natural mentoring relationships should be encouraged and facilitated in prevention efforts for Mexican youths, Mexican-American youths and potentially other Hispanic/Latino youths. PMID:26187913

    2008-01-01

    This study investigated whether a behavioral economic index of the value of rewards available over different time horizons predicted patterns of alcohol consumption shortly after natural resolution when the risk of relapse is high. Using a computerized Interactive Voice Response (IVR) telephone system, untreated problem drinkers (n = 41) self-monitored their daily drinking, monetary expenditures, and surrounding contexts over intervals that ranged from a maximum of 42 to 128 days. Expanded Timeline Followback interviews were conducted before and after the IVR interval and one year after the baseline assessment. Stable resolutions generally and moderation resolutions specifically were associated with proportionally more pre-resolution expenditures on savings and less on alcohol compared to heavy drinking outcomes. The findings replicated and extended earlier research and suggested that the extent to which problem drinkers organized their behavior over longer intervals, even when drinking abusively, helped identify who resolved, including who transitioned to stable moderation.

    The concentration of uranium has been assessed in drinking water samples collected from different locations in Bathinda district, Punjab, India. The water samples are taken from hand pumps and tube wells. Uranium is determined using fission track technique. Uranium concentration in the water samples varies from 2.23+/- 0.05 to 87.05+/- 0.29 microg/L. These values are compared with safe limit values recommended for drinking water. The uranium concentration in almost all drinking water samples is found to be more than the safe limit. Analysis of some heavy metals viz. Zn, Cd, Pb and Cu in water is made. The concentration of sodium, potassium, calcium, magnesium, chlorine and total hardness along with the pH value and conductivity of the water samples are measured. Some of the samples show stunningly high values of these parameters.

Binge drinking was defined as five or more drinks per episode for men and as four or more drinks per episode for women. RESULTS. Overall, 44% of the students (50% of the men and 39% of the women) binged. While demographic factors such as sex and race were significantly related to binge drinking, prior binging in high school was crucial, suggesting that for many students, binge drinking begins before college. The strongest predictors of college binge drinking were residence in a fraternity or sorority, adoption of a party-centered life-style, and engagement in other risky behaviors. CONCLUSIONS. Interventions must be targeted at high school binge drinking as well as at several characteristics of college life--most notably fraternity residence. Legal drinking age fails to predict binge drinking, raising questions about the effectiveness of the legal minimum drinking age of 21 in college alcohol policies. PMID:7604914

    Rationale The α4β2 nicotinic acetylcholine receptor partial agonist varenicline has been reported to reduce drinking among both heavy-drinking smokers and primary alcoholics, and this effect may be related to varenicline-mediated reduction of alcohol craving. Among smokers, varenicline has been reported to modulate cigarette cue-elicited brain activation in several reward-related areas. Objectives This pilot study tested varenicline’s effects on drinking, alcohol craving, and alcohol cue-elicited activation of reward-related brain areas among non-treatment-seeking alcohol-dependent individuals. Methods Thirty-five such individuals (mean age = 30, 57% male, 76% heavy drinking days in the past month, 15 smokers) were randomized to either varenicline (titrated to 2 mg) or placebo for 14 days, and were administered an alcohol cue reactivity fMRI task on day 14. A priori regions of interest (ROIs) were bilateral and medial orbitofrontal cortex (OFC), right ventral striatum (VS), and medial prefrontal cortex (mPFC). Results Despite good medication adherence, varenicline did not reduce heavy drinking days or other drinking parameters. It did, however, increase self-reported control over alcohol-related thoughts and reduced cue-elicited activation bilaterally in the OFC, but not in other brain areas. Conclusions These data indicate that varenicline reduces alcohol craving and some of the neural substrates of alcohol cue reactivity. However, varenicline effects on drinking mediated by cue-elicited brain activation and craving might be best observed among treatment-seekers motivated to reduce their alcohol consumption.

    Objectives. We examined associations between consumption of different types of flavored alcoholic beverages (FABs) and risky drinking and drinking-related harms among underage drinkers. Methods. For the Alcohol Brand Research among Underage Youth study, we applied multivariable logistic regression analyses to data from underage drinkers (n = 1031, aged 13–20 years), recruited from a national Internet panel in 2011 to 2012, to estimate associations between consumption of malt-based drinks; spirits-based, premixed- or ready-to-drink cocktails; and supersized alcopops, alone or in combination, and alcohol-related outcomes. Results. After adjustment for confounding variables, the exclusive consumption of alcopops was associated with episodic heavy drinking (odds ratio [OR] = 4.35; 95% confidence interval [CI] = 1.24, 15.31; P < .05) and alcohol-related injuries (OR = 6.25; 95% CI = 1.34, 29.10; P < .05). Exclusive consumption of cocktails was associated with episodic heavy drinking (odds ratio [OR] = 2.61; 95% CI = 1.26, 5.41; P < .05) and injuries requiring medical attention (OR = 6.50; 95% CI = 2.09, 20.17; P < .001. Exclusive consumption of 2 or more FABs was associated with episodic heavy drinking (OR = 2.78; 95% CI = 1.25, 6.16; P < .05), fighting (OR = 3.30; 95% CI = 1.46, 7.47; P < .001), and alcohol-related injuries (OR = 2.83; 95% CI = 1.43, 5.58; P < .001). Conclusions. FABs present an emerging public health problem among youths. PMID:25713955

    Introduction Despite the strong relationship between smoking and health-related consequences, very few smokers quit. Heavy drinking is a significant risk factor for health consequences, and is implicated in persistent smoking and less success at quitting smoking. Self-efficacy (SE) to abstain from smoking is an important determinant of smoking outcomes and may link alcohol use to poor quit rates. Even though research has demonstrated a strong association between drinking and smoking, and the multiplicative effect of these substances on cancer-related, heavy-drinking smokers has been largely ignored in the literature. Further, research has not taken advantage of innovative methods, such as ecological momentary assessment, to capture the impact of daily factors on smoking cessation outcomes in this particular group. The proposed study identifies daily changing factors that impede or promote SE and future smoking cessation efforts in risky-drinking smokers. Methods and analysis This is an observational study of 84 regular smokers (≥10 cigarettes per day) who drink at risky levels, report a desire to quit in the next 6 months, and show no evidence of psychiatric disturbance, severe history of alcohol withdrawal or drug dependence (excluding nicotine and caffeine). Participants report on their smoking, alcohol consumption and SE related to smoking twice a day for 28 days using interactive voice response (IVR) surveys. Multilevel regression and path models will examine within-person daily associations among drinking, smoking and SE, and how these variables predict the likelihood of future smoking behaviour at 1 and 6 months follow-up. Ethics and dissemination This protocol was approved by an accredited Institutional Review Board. The findings will help us understand the factors that promote or impede smoking cessation among a high-risk group of smokers (heavy-drinking smokers) and will be disseminated through peer-reviewed journal articles and presentations at

    Certain heavy metals are required, as trace elements for normal cellular functions. However, heavy metals are toxic to cells once their levels exceed their low physiological values. The toxicity of heavy metals on microorganisms, and on animals has been well-documented. These interactions may induce the alteration of the primary as well as secondary structures of the DNA and result in mutation(s). The present communication reports the results in determining the mutagenicity and carcinogenicity of ten heavy metals commonly found in polluted areas by using the Salmonella/mammalian-microsome mutagenicity test.

  5. Biological Contribution to Social Influences on Alcohol Drinking: Evidence from Animal Models

    Social factors have a tremendous influence on instances of heavy drinking and in turn impact public health. However, it is extremely difficult to assess whether this influence is only a cultural phenomenon or has biological underpinnings. Research in non-human primates demonstrates that the way individuals are brought up during early development affects their future predisposition for heavy drinking, and research in rats demonstrates that social isolation, crowding or low social ranking can lead to increased alcohol intake, while social defeat can decrease drinking. Neurotransmitter mechanisms contributing to these effects (i.e., serotonin, GABA, dopamine) have begun to be elucidated. However, these studies do not exclude the possibility that social effects on drinking occur through generalized stress responses to negative social environments. Alcohol intake can also be elevated in positive social situations, for example, in rats following an interaction with an intoxicated peer. Recent studies have also begun to adapt a new rodent species, the prairie vole, to study the role of social environment in alcohol drinking. Prairie voles demonstrate a high degree of social affiliation between individuals, and many of the neurochemical mechanisms involved in regulation of these social behaviors (for example, dopamine, central vasopressin and the corticotropin releasing factor system) are also known to be involved in regulation of alcohol intake. Naltrexone, an opioid receptor antagonist approved as a pharmacotherapy for alcoholic patients, has recently been shown to decrease both partner preference and alcohol preference in voles. These findings strongly suggest that mechanisms by which social factors influence drinking have biological roots, and can be studied using rapidly developing new animal models. PMID:20616986

    Repeated cycles of binge alcohol drinking and abstinence are key components in the development of dependence. However, the precise behavioral mechanisms underlying binge-like drinking and its consequences on striatal synaptic physiology remain unclear. In the present study, ethanol and water drinking patterns were recorded with high temporal resolution over 6 weeks of binge-like ethanol drinking using the ‘drinking in the dark' (DID) protocol. The bottle exchange occurring at the beginning of each session prompted a transient increase in the drinking rate that might facilitate the acquisition of ethanol binge-like drinking. Ethanol drinking mice also displayed a ‘front-loading' behavior, in which the highest rate of drinking was recorded during the first 15 min. This rate increased over weeks and paralleled the mild escalation of blood ethanol concentrations. GABAergic and glutamatergic transmission in the dorsal striatum were examined following DID. Spontaneous glutamatergic transmission and the density of dendritic spines were unchanged after ethanol drinking. However, the frequency of GABAA receptor-mediated inhibitory postsynaptic currents was depressed in medium spiny neurons of ethanol drinking mice. A history of ethanol drinking also increased ethanol preference and altered the acute ethanol effects on GABAergic transmission differentially in dorsolateral and dorsomedial striatum. Together, the study shows that the bottle exchange during DID promotes fast, voluntary ethanol drinking and that this intermittent pattern of ethanol drinking causes a depression of GABAergic transmission in the dorsal striatum.

    Binge drinking is associated with clinically significant individual-level and public health consequences. The topography of binge drinking may influence the emergence of consequences, but studies of topography require a higher level of temporal resolution than is typically available in epidemiological research. To address topography across the 5 "peak" years of binge drinking (18 to 23 years), we assessed daily binge drinking via successive 90-day timeline follow-back interviews of 645 young adults (resulting in almost 700,000 data points). Results showed a weekend "pulse" of binge drinking that remained consistent across the entire 5 year span, with occasional holiday-based perturbations. Two-part latent growth curve modeling applied to this dataset showed that the often-observed decrease in drinking associated with "maturing out" was due more to decreased participation in binge drinking occasions, rather than to amounts consumed when drinking (intensity). Similarly, the number of binge drinkers varied by day of the week, but the intensity of binge drinking, for those drinking, varied little by day of the week. This approach also showed distinctive predictors for participation and intensity; baseline expectancies and sociability accounted for individual differences in participation, whereas impulsivity-sensation seeking predicted intensity. Individual patterns of binge drinking participation and intensity also predicted drinking consequences over the 5 years of the study. Given these results, binge drinking patterns may serve as a useful phenotype for future research on pathological drinking. PMID:25961813

    We compared the effects of similarly tasting orange flavored drinks containing 0% (P), 6.4% (E1), and 10% (E2) carbohydrate (CHO) using 12 well-trained cyclists (VO2max = 5.0 l/min-1) on metabolic responses to exercise (EX) and a sprint type performance ride (PR). Each subject completed 3 separate 2 h EX bouts at 65% VO2max followed by a PR identified as the time in sec to complete 500 revolutions at a constant belt resistance of 29.4 N (ANOVA*). The CHO feedings or placebo of 3 ml/kg body weight were given double blind and counter-balanced at 0 min and every 20 min thereafter during EX. Blood samples were drawn and core temperature (Tr) was recorded at 0, 30, 60, 90, and 120 min of EX and 1 min post PR. Blood samples were analyzed for glucose (G) and lactate [LA-]. Blood G at 0 min were similar; however, at 120 min, G was 3.96 mM for P*, 4.57 mM for E1, and 4.77 mM for E2. Blood [LA-] remained similar throughout EX averaging (P, 2.6 mM; E1, 2.9 mM; E2, 2.5 mM). Tr at 120 min was also similar (P, 38.5 degrees C; E1, 38.6 degrees C; E2, 38.3 degrees C). Mean PR times for P(264.4 s)**, E1 (255.3 s)*, E2 (252.4 s)* indicate consumption of a CHO drink during EX improves PR. Furthermore, a 10% CHO drink improves PR more than a 6.4% CHO drink.

    Imagine drinking water that you wring out of the sponge you’ve just used to wash your car. This is what is happening around the world. Rain and snow pass through soil polluted with pesticides, poisonous metals and radionuclides into the underground lakes and streams that supply our drinking water. “We need to understand this natural system better to protect our groundwater and, by extension, our drinking water,” said Pacific Northwest National Laboratory’s Applied Geology and Geochemistry Group Manager, Wayne Martin. Biologists, statisticians, hydrologists, geochemists, geologists and computer scientists at PNNL work together to clean up contaminated soils and groundwater. The teams begin by looking at the complexities of the whole environment, not just the soil or just the groundwater. PNNL researchers also perform work for private industries under a unique use agreement between the Department of Energy and Battelle, which operates the laboratory for DOE. This research leads to new remediation methods and technologies to tackle problems ranging from arsenic at old fertilizer plants to uranium at former nuclear sites. Our results help regulators, policy makers and the public make critical decisions on complex environmental issues.

    The Safe Drinking Water Act of 1974 represents an important step in improving the quality of public water supply in the United States. However, it fails to address two important problems: (1) The 1970 Public Health Service Community Water Supply Survey revealed that small public water supply systems often deliver poor quality water. The Act does not assure that these supplies will now receive appropriate attention; furthermore, the Act does not address the needs of the 50 million people not now served by public water systems; (2) About one-third of our population draws its drinking waters from polluted sources. The decisions to use these low cost sources were made generations ago when consumers could be protected from water-borne infectious disease. A new problem has now arisen--the presence of numerous synthetic organic chemicals of uncertain health consequence, not removed by conventional water treatment. The Act does not address this problem. Regionalization and the integration of water resource and water pollution control authorities are proposed as a reasonable solution to these problems. The development of dual water supply systems in order to conserve scarce pure water sources for human consumption appears to be a feasible way to avoid using polluted waters for drinking. The development of dual supplies would be enhanced by regionalization and integration of water authorities. PMID:937609

    With the worldwide consumption of energy drinks increasing in recent years, concerns have been raised both in the scientific community and among the general public about the health effects of these products. Recent studies provide data on consumption patterns in Europe; however, more research is needed to determine the potential for adverse health effects related to the increasing consumption of energy drinks, particularly among young people. A review of the literature was conducted to identify published articles that examined the health risks, consequences, and policies related to energy drink consumption. The health risks associated with energy drink consumption are primarily related to their caffeine content, but more research is needed that evaluates the long-term effects of consuming common energy drink ingredients. The evidence indicating adverse health effects due to the consumption of energy drinks with alcohol is growing. The risks of heavy consumption of energy drinks among young people have largely gone unaddressed and are poised to become a significant public health problem in the future. PMID:25360435

    Heavy drinkers prior to college have been shown to increase their drinking in college via their self-selection into the Greek societies and subsequent Greek influence on their drinking. This study characterized the dual mechanisms underlying these processes: (a) the Greek selection on the basis of personality and precollege drinking and (b) the Greek influence through alcohol-conducive environmental factors. Prospective data obtained in the summer prior to college and over the first 6 semesters of college (N = 3,099) indicated strong precollege drinking-based selection, strong initial influence immediately after college entrance, and sustained influence afterward. Impulsivity/novelty seeking was associated with Greek affiliation both directly and indirectly via precollege drinking, whereas extraversion and neuroticism were associated with Greek affiliation largely independent of precollege drinking. Greek affiliation was related to higher levels of drinking norms immediately after college entrance and alcohol availability by the sophomore year, but not afterward, after controlling for prior drinking. Findings highlight the diverse mechanisms underlying accentuation of risky drinking over the transition to college and during the college years, through dynamic interplay between individuals and high-risk environments.

    Heavy metals in wastewater sewage sludge (biosolids), applied to land, contaminate soils. Phytoremediation, the use of plants to clean up toxic heavy metals, might remove them. Chelating agents are added to soil to solubilize the metals for enhanced phytoextraction. Yet no studies follow the displacement and leaching of heavy metals in soil with and without roots following solubilization with chelates. The objective of this work was to determine the mobility of heavy metals in biosolids applied to the surface of soil columns (76 cm long; 17 cm diam.) with or without plants (barley; Hordeum vulgare L.). Three weeks after barley was planted, all columns were irrigated with the disodium salt of the chelating agent, EDTA (ethylenediamine tetraacetic acid) (0.5 g/kg soil). Drainage water, soil, and plants were analyzed for heavy metals (Cd, Cu, Fe, Mn, Ni, Pb, Zn). Total concentrations of the heavy metals in all columns at the end of the experiment generally were lower in the top 30 cm of soil with EDTA than without EDTA. The chelate increased concentrations of heavy metals in shoots. With or without plants, the EDTA mobilized Cd, Fe, Mn, Ni, Pb, and Zn, which leached to drainage water. Drainage water from columns without EDTA had concentrations of these heavy metals below detection limits. Only Cu did not leach in the presence of EDTA. Even though roots retarded the movement of Cd, Fe, Mn, Ni, Pb, and Zn through the EDTA-treated soil from 1 d (Cd) to 5 d (Fe), the drainage water from columns with EDTA had concentrations of Cd, Fe, Mn, and Pb that exceeded drinking water standards by 1.3, 500, 620, and 8.6 times, respectively. Because the chelate rendered Cd, Fe, Mn, Ni, Pb, and Zn mobile, it is suggested that the theory for leaching of soluble salts, put forward by Nielsen and associates in 1965, could be applied to control movement of the heavy metals for maximum uptake during chelate-assisted phytoremediation.

    The 2001 Harvard School of Public Health College Alcohol Study surveyed students at 119 4-year colleges that participated in the 1993, 1997, and 1999 studies. Responses in the 4 survey years were compared to determine trends in heavy alcohol use, alcohol-related problems, and encounters with college and community prevention efforts. In 2001, approximately 2 in 5 (44.4%) college students reported binge drinking, a rate almost identical to rates in the previous 3 surveys. Very little change in overall binge drinking occurred at the individual college level. The percentages of abstainers and frequent binge drinkers increased, a polarization of drinking behavior first noted in 1997. A sharp rise in frequent binge drinking was noted among students attending all-women's colleges. Other significant changes included increases in immoderate drinking and harm among drinkers. More students lived in substance-free housing and encountered college educational efforts and sanctions resulting from their alcohol use.
