Drunk in Public, Drunk in Private: The Relationship Between College Students, Drinking Environments and Alcohol Consumption

This study examines environmental differences in public (bars) and private (parties) drinking settings among of-age (21 and up years of age) and underage (18–20 years of age) college students attending college near the US/Mexico border. A random telephone survey of graduate and undergraduate students attending two large public universities in the southwestern United States was conducted during the 2000–2003 academic years. A university-based social science research laboratory conducted the telephone interviews with respondents who reported an occasion in the past 28 days where alcohol was being consumed (N = 4,964). The data were analyzed using ordinary least squares multiple regression. The results suggests that drinking settings contributed to the amount of alcohol consumed by respondents. Additionally, environmental factors contributing to drinking vary by setting. In general, having many people intoxicated at an event, BYOB parties, playing drinking games, and having illicit drugs available contribute to heavier drinking.

Blood alcohol concentrations among bar patrons: A multi-level study of drinking behavior.

This paper presents data from a study that collected observational data, survey data, and breath samples to estimate blood alcohol concentrations (BrAC) from patrons attending 30 bars. The study examines: (1) drinking behavior and settings prior to going to a bar; (2) characteristics of the bar where respondents are drinking; (3) person and environmental predictors of BrAC change (entrance to exit). Purposive sampling of bars that cater to young adults gave a sample of 30 bars. Patrons were randomly selected from bars (n=839). Approximately half of the sample was female (48.7%). Nearly three-quarters of participants reported drinking before attending the bar. Serving practices of the bars were observed; majority of bars served excessive amounts of alcohol in short periods of time. On average, those who drank before attending the bar had BrACs at approximately half the legal limit. Implications for responsible beverage service coupled with law enforcement strategies are discussed.

College Undergraduate Ritalin Abusers in Southwestern California: Protective and Risk Factors

During the past five years, a few studies have reported that college students are using stimulants such as Ritalin without a prescription. To date, studies on college Ritalin/Adderall use have been from samples in the eastern or midwestern U.S. This study was designed to examine risk and protective factors associated with Ritalin/Adderall use among a college sample in Southern California. Our findings indicate that 11.2% of students reported past year and over 4% reported past 30 day use of Ritalin/Adderall. In our final analysis, students with lower GPAs, in a fraternity/sorority, not in a committed relationship, and who smoke and use other drugs were more likely to report past year and past 30 day Ritalin/Adderall use. Implications for prevention programming of these findings are discussed.

Self-Reported Age of Onset and Telescoping for Cigarettes, Alcohol, and Marijuana: Across Eight Years of the National Longitudinal Survey of Youth.

Smoking, drinking, and illicit drug use are leading causes of morbidity and mortality, both during adolescence as well as later in life. The determination of how well national and local policy and intervention efforts address teen substance use depends largely on the collection of valid and accurate data. Assessments of substance use rely heavily on retrospective self-report measures, but the reliability and validity, however, may be limited by various sources of measurement error. This study utilizes four waves of data from the National Longitudinal Survey of Youth spanning eight years. Results from multiple linear regression analyses showed that the single most consistent variable associated with telescoping was the number of years since the substance was first reported. Time since first report was the single consistent variable and was strongly associated with telescoping in each wave-to-wave comparison for all three substances under study. Implications for policy and research are discussed.

The Effect of Cigarette Price Increases on Smoking Cessation in California

We investigated whether smoking cessation increased in California after a cigarette manufacturer’s retail price increase and an increase in the state cigarette excise tax. The sample for this study was drawn from the 1996 and 1999 California Tobacco Surveys. The rate of unsuccessful and successful quit attempts and the rate of abstinence were calculated for each month of the 14-month period preceding each survey administration. We combined the monthly rates for both surveys and used multiple regression modeling to test whether the proportion of smokers reporting a quit attempt and the proportion of smokers reporting abstinence increased during the period following the price increases. We included several covariates in our models to control for factors other than the price increases that could account for any increases observed in quit attempts and abstinence. Because smokers recall quits occurring closer to the date of the survey better than quits occurring further back in time, we included a term in the models representing the number of months elapsed between the survey administration and the reported quit. We also included terms in the models representing the months before and after the over-the-counter (OTC) availability of the nicotine patch and nicotine gum in 1996 to control for the increase in smoking cessation observed following the availability of OTC nicotine replacement therapy (NRT). Lastly, in order to control for increased quits made in January as a result of New Year’s resolutions, we included a term in our models for quit attempts and successful quits (abstinence) made during this month. Results of the regression analyses indicated a significantly greater proportion of smokers reported quit attempts (p < 0.05) in the months immediately following the cigarette price increases (after November 1998); however, a significant increase in abstinence was only observed from December 1998 through March 1999 (p < 0.05) relative to abstinence occurring before the price increases.

Predictors of partying prior to bar attendance and subsequent BrAC

Pre-drinking (e.g., pre-gaming, pre-loading) occurs frequently among young adult and college-aged drinkers and is associated with increased intoxication as well as alcohol-related problems. The purpose of the following study was to examine pre-drinking behaviors in situ, and to test whether drinking intentions mediate the relationship between heavy episodic drinking history and pre-drinking behaviors. We randomly selected a sample of 1040 young adults bar patrons at 32 bars in a major metropolitan city in Southern California and asked participants to complete an interview concerning drinking behavior as well as provide a breath sample used to measure breath alcohol concentration. We used multilevel path analysis to test two meditational models. Results showed drinking intentions mediated the relationship between heavy episodic drinking history and pre-drinking behavior as well as the relationship between heavy episodic drinking history and level of pre-drinking intoxication. Gender did not moderate these meditational relationships suggesting similar pre-drinking behaviors for both men and women. Potential methods to prevent pre-drinking behaviors in this population of young people are discussed.

A population-based examination of racial and ethnic differences in receiving physicians' advice to quit smoking

We examined the rate of physician-delivered smoking cessation advice in the United States over time for five different racial/ethnic groups. We analyzed three waves (1992--1993, 1995--1996, 1998--1999) of population-based survey data (Tobacco Use Supplement of the Current Population Survey) to examine the relationship between a smokers race/ethnicity and past-year receipt of physician-delivered smoking cessation advice. Results of a multivariate logistic regression showed no difference in the receipt of advice as a function of a smokers race/ethnicity in any of the surveys, with the exception of 1998--1999, after controlling for factors such as smokers gender, years of education, household income, and cigarettes smoked per day. In the 1998--1999 survey, Asian smokers were more likely to report receiving smoking cessation advice from a physician relative to non-Hispanic White smokers. With the exception of American Indian/Alaska Native smokers, the receipt of advice by each racial/ethnic group increased significantly from the 1992--1993 survey to the 1998--1999 survey, after controlling for gender, age, education, and cigarettes smoked per day. Because rates of advice for American Indian/Alaska Native smokers did not increase over time, specific public health interventions should be developed and integrated into medical settings serving smokers from American Indian/Alaska Native communities.

The Effect of Over-the-Counter Sales of the Nicotine Patch and Nicotine Gum on Smoking Cessation in California

The Food and Drug Administration approved over-the-counter (OTC) sale of nicotine gum and nicotine patches in 1996. We used data from the 1996 California Tobacco Survey to compare the rates of nicotine replacement therapy (NRT) use and smoking abstinence in California for each month during a period immediately preceding and immediately following the OTC availability of nicotine gum and patches. For smokers eligible to report a quit attempt, the proportion making a quit attempt using NRT and the proportion remaining abstinent was calculated for each of the 12 months prior to the survey interview. Multiple regression modeling of quit attempts and abstinence included a term for the number of months between the quit attempt and survey interview and dummy variables for the months before and after the OTC availability of NRT. Results showed a significant increase in the fraction of smokers using the patch (P < 0.01) and gum (P < 0.05) immediately following their availability OTC. There was also a significantly higher proportion of smokers reporting abstinence with gum use (P < 0.01) and a significant increase in reported abstinence with patch use (P < 0.01) during the period of time immediately following the availability of these products without a prescription. The results of this study suggest that removing the prescription status of NRT products resulted in an immediate increase in quit attempts and smoking abstinence with the use of nicotine gum or patches.

Three exploratory studies of college theme parties

INTRODUCTION AND AIMS The objectives of this exploratory research were to (1) explore the characteristics and risks associated with college theme parties, (2) assess differences in risk associated with college theme parties compared to non-theme parties and (3) to assess differences in risk associated with risqué theme parties as compared to non-risqué theme parties. DESIGN AND METHODS We used a mixed methods design. Results are presented from three exploratory studies of alcohol consumption in college theme parties: (1) four qualitative focus groups of students who have attended such events, (2) a web-based survey and (3) a multi-level (observational, survey, breath blood alcohol samples) study of 226 college parties, 29 of which were themed events. Focus group participants included a convenience sample of 17 college students aged 18-24 years; participants for the web survey included a convenience sample of 407 college students; participants for the multi-level study of college parties included 1725 randomly selected individuals at college parties. RESULTS Themes tended to be highly sexualized. Compared to non-themed parties, theme parties have been observed to be more rowdy, louder, involve drinking games, feature kegs and feature hard liquor. DISCUSSION AND CONCLUSIONS Themed parties are associated with heavy drinking and are consistent with environments sought by heavy drinkers. As a result, themed parties are marked by a greater number of alcohol-related problems. Further research is needed to understand more clearly the risks involved in themed and risqué themed events.

Self-Report Stability of Adolescent Cigarette Use Across Ten Years of Panel Study Data

This study is the first to examine adolescent cigarette report stability over 10 years. Six waves of data were utilized from the National Longitudinal Survey of Youth. This study examined internal/logical consistency and external consistency. Report stability was higher for lifetime use reports than the age of onset reports. Wave-by-wave differences revealed stability increased across time, with one-third denying use in the first two wave comparisons but dropping to 20% by the last comparison. Overall, report agreement was higher for females, older adolescents, and non-Hispanic/non-black youths. Implications regarding misclassification of users for prevention programs and measurement issues are discussed.
