Drinking Frequency (drinking + frequency)
Selected AbstractsThe importance of drinking frequency in evaluating individuals' drinking patterns: implications for the development of national drinking guidelinesADDICTION, Issue 7 2009Catherine Paradis ABSTRACT Aims This paper examines the relationship between frequency of drinking, usual daily consumption and frequency of binge drinking, taking into consideration possible age and gender differences. Participants and design Subjects were 10 466 current drinkers (5743 women and 4723 men) aged between 18 and 76 years, who participated in the GENACIS Canada (GENder Alcohol and Culture: an International Study) study. Setting Canada. Measurements The independent variable was the annual drinking frequency. The dependent variables were the usual daily quantity consumed, annual, monthly and weekly frequency of binge drinking (five drinks or more on one occasion). Findings Logistic regressions show (i) that those who drink less than once a week are less likely than weekly drinkers to take more than two drinks when they do drink; (ii) that the usual daily quantity consumed by weekly drinkers is not related to their frequency of drinking; but that (iii) the risk and frequency of binge drinking increase with the frequency of drinking. Conclusions Given that risk and frequency of binge drinking among Canadians increases with their frequency of drinking, any public recommendation to drink moderately should be made with great caution. [source] Alcohol outlet density and university student drinking: a national studyADDICTION, Issue 7 2008Kypros Kypri ABSTRACT Aims To examine the geographic density of alcohol outlets and associations with drinking levels and related problems among university students. Design Cross-sectional survey study using geospatial data, with campus-level and individual-level analyses. Participants A total of 2550 students (mean age 20.2, 60% women) at six university campuses in New Zealand (63% response). Measurements Counts of alcohol outlets within 3 km of each campus were tested for their non-parametric correlation with aggregated campus drinking levels and related problems. Generalized estimating equations were used to model the relation between outlet counts within 1 km and 3 km of student residences and individual drinking levels/problems, with control for gender, age, ethnicity and high school binge drinking frequency, and adjustment for campus-level clustering. Findings Correlations for campus-level data were 0.77 (P = 0.07) for drinking and personal problems, and 0.31 (P = 0.54) for second-hand effects. There were consistent significant associations of both on- and off-licence outlet densities with all outcomes in student-level adjusted models. Effects were largest for 1 km densities and off-licence outlets. Conclusions There are positive associations between alcohol outlet density and individual drinking and related problems. Associations remain after controlling for demographic variables and pre-university drinking, i.e. the associations are unlikely to be due to self-selection effects. Increasing alcohol outlet density, and particularly off-licences, may increase alcohol-related harm among university students. [source] Drinking patterns, drinking contexts and alcohol-related aggression among late adolescent and young adult drinkersADDICTION, Issue 7 2005Samantha Wells ABSTRACT Aims The main objectives of this study were to determine: (1) the relative roles of heavy episodic drinking (HED), drinking frequency and drinking volume in explaining alcohol-related aggression and (2) whether drinking context variables (i.e. usual drinking locations, typical drinking companions and extent of peer drinking) confound or modify the relationship between HED and alcohol-related aggression or whether they predict alcohol-related aggression independently. Design A secondary analysis of the US National Longitudinal Survey of Youth was conducted. Alcohol-related aggression (denoted fights after drinking) was measured based on self-reports of arguments or fights that occurred during or after drinking in the previous 12 months. Participants A composite sample of drinkers, ages 17,21, from the 1994, 1996 and 1998 Young Adult surveys (n = 738) was used. Findings Frequency of drinking and drinking volume largely confounded the association between HED and fights after drinking. Usually drinking in public locations away from home versus private locations was found to be significantly associated with a greater likelihood of fights after drinking among females. Among males, usual drinking location modified the relationship between drinking frequency and alcohol-related aggression, with the greatest risk of aggression for males who drank frequently and usually drank in public locations away from home. Conclusions Programs designed to reduce drinking frequency in this population and to increase the safety of drinking locations in public places away from home may prove to be beneficial in reducing alcohol-related aggression. [source] Individual Differences in Alcohol Drinking Frequency Are Associated With Electrophysiological Responses to Unexpected NonrewardsALCOHOLISM, Issue 4 2010Ingmar H. A. Franken Background:, It has been suggested that alcohol use is related to sensitivity of the reward system. Although there are several studies using self-reported measures supportive of this notion, objective biological data in humans on this issue are lacking. Aims:, This study is designed to test whether alcohol drinking frequency is associated with electrophysiological indices of reward processing. Materials and Methods:, In a passive gambling task, stimuli predicted the presence (reward) and absence (nonreward) of rewards resulting in P2 and medial frontal negativity (MFN) indices of reward processing. Forty-seven undergraduate students were asked about their habitual drinking frequency and the P2 and MFN to stimuli predicting reward were measured. Results:, Most importantly, the MFN to unpredicted nonrewards at the frontal midline (Fz) location correlated significantly with drinking frequency, with frequent drinkers showing larger MFN amplitudes. The results did not show a significant association between frequency and alcohol drinking and P2. Discussion:, Although several studies showing increased reward-sensitivity in addictive behaviors, the present results indicate that, in frequent alcohol drinkers, electrophysiological responsiveness is particularly activated by unpredicted nonrewards. In general, this may point to the involvement of the reward system in alcohol drinking frequency. Conclusion:, More specifically, the results demonstrate an increased vulnerability of high frequency drinkers to signals of (frustrative) nonrewards. [source] Drinking Patterns and Myocardial Infarction: A Linear Dose,Response ModelALCOHOLISM, Issue 2 2009Marcia Russell Background:, The relation of alcohol intake to cardiovascular health is complex, involving both protective and harmful effects, depending on the amount and pattern of consumption. Interpretation of data available on the nature of these relations is limited by lack of well-specified, mathematical models relating drinking patterns to alcohol-related consequences. Here we present such a model and apply it to data on myocardial infarction (MI). Methods:, The dose,response model derived assumes: (1) each instance of alcohol use has an effect that either increases or decreases the likelihood of an alcohol-related consequence, and (2) greater quantities of alcohol consumed on any drinking day add linearly to these increases or decreases in risk. Risk was reduced algebraically to a function of drinking frequency and dosage (volume minus frequency, a measure of the extent to which drinkers have more than 1 drink on days when they drink). In addition to estimating the joint impact of frequency and dosage, the model provides a method for calculating the point at which risk related to alcohol consumption is equal to background risk from other causes. A bootstrapped logistic regression based on the dose,response model was conducted using data from a case-control study to obtain the predicted probability of MI associated with current drinking patterns, controlling for covariates. Results:, MI risk decreased with increasing frequency of drinking, but increased as drinking dosage increased. Rates of increasing MI risk associated with drinking dosage were twice as high among women as they were among men. Relative to controls, lower MI risk was associated with consuming < 4.55 drinks per drinking day for men (95% CI: 2.77 to 7.18) and < 3.08 drinks per drinking day for women (95% CI: 1.35 to 5.16), increasing after these cross-over points were exceeded. Conclusions:, Use of a well-specified mathematical dose,response model provided precise estimates for the first time of how drinking frequency and dosage each contribute linearly to the overall impact of a given drinking pattern on MI risk in men and women. [source] Concurrent and Discriminant Validity of DSM-IV Symptoms of Impaired Control Over Alcohol Consumption in AdolescentsALCOHOLISM, Issue 4 2002Tammy Chung Background: Little research has examined impaired control over alcohol consumption in adolescents. This study examined the concurrent and discriminant validity of two DSM-IV dependence criteria that reflect impaired control over drinking: "using more or longer than intended" (Larger/Longer) and "persistent desire or unsuccessful efforts to quit or cut down" (Quit/Cut Down). Methods: Adolescent drinkers, ages 13,19 (N= 173), were recruited from addictions treatment (76%) and community sources (24%). A modified SCID that included assessment of alcohol craving and questionnaires measuring dependence severity, attempts to limit drinking, and impulsivity were administered. Results: Larger/Longer had higher prevalence and an earlier onset than Quit/Cut Down, suggesting that the symptoms respectively represent milder and more severe manifestations of impaired control over drinking. Both symptoms were associated with drinking frequency, dependence severity, episodes of passing out, and an independent measure of unsuccessful attempts to limit drinking. Alcohol craving was associated with both Larger/Longer and Quit/Cut Down. Impulsivity was correlated with Larger/Longer but not Quit/Cut Down. Conclusions: Larger/Longer and Quit/Cut Down demonstrated adequate concurrent validity. The two symptoms were distinguished by severity and differential relations with impulsivity, suggesting that Larger/Longer and Quit/Cut Down reflect different types of impaired control over alcohol consumption. Results suggest the need for improved description and scaling of the impaired control construct in adolescents. [source] Moderate alcohol intake increases fibrosis progression in untreated patients with hepatitis C virus infectionJOURNAL OF VIRAL HEPATITIS, Issue 3 2002J. Westin Although excessive alcohol consumption in combination with hepatitis C virus (HCV) infection is known to increase the risk of liver cirrhosis, the effect of moderate alcohol intake remains to be elucidated. The aim of this study was to evaluate the effect of moderate alcohol consumption on fibrosis progression in HCV infection. A group of 78 patients with HCV infection and moderate alcohol consumption were analysed retrospectively. All patients had undergone two liver biopsies, with a median time between biopsies of 6.3 years, and had not received any antiviral therapy. Their lifetime drinking history was recorded. All patients except one had daily alcohol consumption below 40 g of ethanol (median 4.8 g/day, interquartile range 1.1,11.6 g/day) during the period between the biopsies. The patients whose liver fibrosis had deteriorated had a higher total alcohol consumption and higher drinking frequency between the biopsies. The degree of fibrosis progression was greater in patients with a total alcohol intake and drinking frequency above the median level for the group. A multiple logistic regression analysis showed that drinking frequency and time between biopsies were independently associated with fibrosis progression. Hence, even moderate alcohol intake seems to increase fibrosis progression in HCV-infected patients. From that point of view, total abstention ought to be recommended. If this is not achieved, occasional use of alcohol is probably less harmful than daily drinking for patients with low or moderate alcohol consumption. [source] | ||||||||||
