Alcohol Availability (alcohol + availability)
Selected AbstractsAlcohol Availability and Intimate Partner Violence Among US CouplesALCOHOLISM, Issue 1 2009Christy M. McKinney Objectives:, We examined the relation between alcohol outlet density (the number of alcohol outlets per capita by zip code) and male-to-female partner violence (MFPV) or female-to-male partner violence (FMPV). We also investigated whether binge drinking or the presence of alcohol-related problems altered the relationship between alcohol outlet density and MFPV or FMPV. Methods:, We linked individual and couple sociodemographic and behavioral data from a 1995 national population-based sample of 1,597 couples to alcohol outlet data and 1990 US Census sociodemographic information. We used logistic regression for survey data to estimate unadjusted and adjusted odds ratios between alcohol outlet density and MFPV or FMPV along with 95% confidence intervals (CIs) and p -values. We used a design-based Wald test to derive a p -value for multiplicative interaction to assess the role of binge drinking and alcohol-related problems. Results:, In adjusted analysis, an increase of one alcohol outlet per 10,000 persons was associated with a 1.03-fold increased risk of MFPV (p -value for linear trend = 0.01) and a 1.011-fold increased risk of FMPV (p -value for linear trend = 0.48). An increase of 10 alcohol outlets per 10,000 persons was associated with 34% and 12% increased risk of MFPV and FMPV respectively, though the CI for the association with FMPV was compatible with no increased risk. The relationship between alcohol outlet density and MFPV was stronger among couples reporting alcohol-related problems than those reporting no problems (p -value for multiplicative interaction = 0.01). Conclusions:, We found that as alcohol outlet density increases so does the risk of MFPV and that this relationship may differ for couples who do and do not report alcohol-related problems. Given that MFPV accounts for the majority of injuries related to intimate partner violence, policy makers may wish to carefully consider the potential benefit of limiting alcohol outlet density to reduce MFPV and its adverse consequences. [source] Alcohol control policies and alcohol consumption by youth: a multi-national studyADDICTION, Issue 11 2009Mallie J. Paschall ABSTRACT Aims The study examined relationships between alcohol control policies and adolescent alcohol use in 26 countries. Design Cross-sectional analyses of alcohol policy ratings based on the Alcohol Policy Index (API), per capita consumption and national adolescent survey data. Setting Data are from 26 countries. Participants Adolescents (aged 15,17 years) who participated in the 2003 European School Survey Project on Alcohol and Other Drugs (ESPAD) or national secondary school surveys in Spain, Canada, Australia, New Zealand and the United States. Measurements Alcohol control policy ratings based on the API; prevalence of alcohol use, heavy drinking and first drink by age 13 based on national secondary school surveys; per capita alcohol consumption for each country in 2003. Analysis Correlational and linear regression analyses were conducted to examine relationships between alcohol control policy ratings and past 30-day prevalence of adolescent alcohol use, heavy drinking and having first drink by age 13. Per capita consumption of alcohol was included as a covariate in regression analyses. Findings More comprehensive API ratings and alcohol availability and advertising control ratings were related inversely to the past 30-day prevalence of alcohol use and prevalence rates for drinking three to five times and six or more times in the past 30 days. Alcohol advertising control was also related inversely to the prevalence of past 30-day heavy drinking and having first drink by age 13. Most of the relationships between API, alcohol availability and advertising control and drinking prevalence rates were attenuated and no longer statistically significant when controlling for per capita consumption in regression analyses, suggesting that alcohol use in the general population may confound or mediate observed relationships between alcohol control policies and youth alcohol consumption. Several of the inverse relationships remained statistically significant when controlling for per capita consumption. Conclusions More comprehensive and stringent alcohol control policies, particularly policies affecting alcohol availability and marketing, are associated with lower prevalence and frequency of adolescent alcohol consumption and age of first alcohol use. [source] Effects of home access and availability of alcohol on young adolescents' alcohol useADDICTION, Issue 10 2007Kelli A. Komro ABSTRACT Aims The purpose of the present study was to examine the effects of parental provision of alcohol and home alcohol accessibility on the trajectories of young adolescent alcohol use and intentions. Design Data were part of a longitudinal study of alcohol use among multi-ethnic urban young adolescents who were assigned randomly to the control group of a prevention trial. Setting Data were collected from a cohort of youth, and their parents, who attended public schools in Chicago, Illinois (2002,2005). Participants The sample comprised the 1388 students, and their parents, who had been assigned randomly to the control group and were present and completed surveys at baseline, in the beginning of 6th grade (age 12). The sample was primarily low-income, and African American and Hispanic. Measurements Students completed self-report questionnaires when in the 6th, 7th and 8th grades (age 12,14 years; response rates 91,96%). Parents of the 6th grade students also completed questionnaires (70% response rate). Findings Student report, at age 12, of parental provision of alcohol and home alcohol availability, and parental report of providing alcohol to their child and the accessibility of alcohol in the home, were associated with significant increases in the trajectories of young adolescent alcohol use and intentions from ages 12,14 years. Student report of receiving alcohol from their parent or taking it from home during their last drinking occasion were the most robust predictors of increases in alcohol use and intentions over time. Conclusions Results indicate that it is risky for parents to allow children to drink during early adolescence. When these findings are considered together with the risks associated with early onset of alcohol use, it is clear that parents can play an important role in prevention. [source] Long-Lasting Resistance to Extinction of Response Reinstatement Induced by Ethanol-Related Stimuli: Role of Genetic Ethanol PreferenceALCOHOLISM, Issue 10 2001Roberto Ciccocioppo Background: The conditioning of ethanol's reinforcing effects with specific environmental stimuli is thought to be a critical factor in long-lasting relapse risk associated with alcoholism. To study the significance of such learning factors in the addictive potential of ethanol, this experiment was designed (1) to characterize the effects of stimuli associated with alcohol availability on the reinstatement of responding at a previously ethanol-paired lever in rats with genetically determined ethanol preference versus nonpreference and (2) to examine the persistence of the motivating effects of these stimuli over time. Methods: Male alcohol-preferring (P) and alcohol-nonpreferring (NP) rats were trained to operantly self-administer ethanol (10% w/v) or water on a fixed-ratio 1 schedule in a 30-min daily session. Ethanol and water sessions were scheduled in random sequence across training days. Ethanol availability was signaled by an olfactory discriminative stimulus (banana extract, S+), and each lever press was paired with brief presentation of the conditioning chamber's house light (CS+). The discriminative stimulus signaling water availability (i.e., nonreward) consisted of anise odor (S,), and lever-responses during water sessions were paired with a brief white noise generation (CS,). The rats then were placed on extinction conditions during which ethanol and water, as well as the corresponding stimuli, were withheld. The effects of noncontingent exposure to the S+ versus S, paired with response-contingent presentation of the CS+ versus CS, on responding at the previously active lever were then determined in 30-min reinstatement sessions. To study the resistance to extinction of the effects of the ethanol-associated stimuli, additional tests were conducted at 3-day intervals for a total of 50 days. Results: The number of ethanol-reinforced responses during self-administration training was significantly greater in P than in NP rats (p < 0.01). After extinction, a significant recovery of responding was observed in both groups of rats under the stimulus conditions associated with ethanol (S+/CS+) but not those associated with water (S,/CS,). However, the response reinstatement was significantly greater in P than NP rats (p < 0.01). In addition, the results revealed a considerable resistance to extinction to the effects of the ethanol-associated stimuli. Throughout the 50-day test period, responding remained significantly above extinction levels in both P and NP rats (p < 0.01), but with an overall greater number of responses in P than NP rats (p < 0.05). Conclusions: The results support the hypothesis that conditioning factors contribute importantly to compulsive ethanol seeking and long-lasting vulnerability to relapse. In addition, the results suggest that genetic predisposition toward heightened ethanol intake extends to greater susceptibility to the motivating effects of ethanol-related environmental stimuli.
