Event-level analyses of energy drink consumption and alcohol intoxication in bar patrons

AIM To assess event-level associations between energy drink consumption, alcohol intoxication, and intention to drive a motor vehicle in patrons exiting bars at night. METHOD Alcohol field study. Data collected in a U.S. college bar district from 802 randomly selected and self-selected patrons. Anonymous interview and survey data were obtained as well as breath alcohol concentration (BrAC) readings. RESULTS Results from logistic regression models revealed that patrons who had consumed alcohol mixed with energy drinks were at a 3-fold increased risk of leaving a bar highly intoxicated (BrAC> or =0.08g/210L), as well as a 4-fold increased risk of intending to drive upon leaving the bar district, compared to other drinking patrons who did not consume alcoholic beverages mixed with energy drinks. DISCUSSION These event-level associations provide additional evidence that energy drink consumption by young adults at bars is a marker for elevated involvement in nighttime risk-taking behavior. Further field research is needed to develop sound regulatory policy on alcohol/energy drink sales practices of on-premise establishments.

The Feasibility of a Web-Based Surveillance System to Collect Health Risk Behavior Data from College Students

This study examined the feasibility of collecting health risk behavior data from undergraduate students using a Web-based survey. Undergraduates were randomly selected and assigned randomly to a mail survey group and a Web survey group. There were no statistically significant differences between the two groups for demographics, response rates, item completion, and item completion errors. Yet differences were found for response time and sensitive item completion. This is the first study to demonstrate the feasibility of collecting health risk behavior data from undergraduates using the Web. Undergraduates are just as likely to respond to a Web survey compared with a mail survey and more likely to answer socially threatening items using this method. Also, the Web format and protocol required less time to administer. Researchers and practitioners conducting health survey research with college students or other homogeneous populations who have access to e-mail and the Web should consider using a Web-based survey design as an alternative to a mail, self-administered survey. In such a population, a Web-based survey should not discourage participation, particularly if participants are interested in the questionnaire content.

Relationship between Frequency and Intensity of Physical Activity and Health Behaviors of Adolescents

BACKGROUND While studies have determined the importance of physical activity in advancing health outcomes, relatively few have explored the relationship between exercise and various health behaviors of adolescents. The purpose of this study is to examine the relationship between frequency and intensity of physical activity and both health risk and health promoting behaviors of adolescents. METHODS Data were collected from 822 students attending a large, diverse suburban high school in northeast Florida using a self-administered survey. Multivariate analysis of variance (MANOVA) and analysis of variance (ANOVA) tests examined differences on mean health behavior measures on 3 exercise frequency levels (low, medium, and high) and 2 intensity levels (vigorous physical activity [VPA] and moderate physical activity [MPA]). RESULTS Results showed adolescents engaged in high levels of VPA used marijuana less frequently (p = .05) and reported heavy use of marijuana less frequently (p = .03); consumed greater numbers of healthy carbohydrates (p < .001) and healthy fats in their diets (p < .001); used stress management techniques more frequently (p < .001); and reported a higher quality of sleep (p = .01) than those engaged in low levels of VPA. Fewer differences were found on frequency of MPA and health behaviors of adolescents. CONCLUSIONS These findings suggest that adolescents who frequently participate in VPA may be less likely to engage in drug use, and more likely to participate in a number of health promoting behaviors. Longitudinal and experimental studies are needed to determine what role frequent VPA may play in the onset and maintenance of health enhancing and protecting behaviors among adolescent populations.

Healthy workplaces: the effects of nature contact at work on employee stress and health.

Objectives. Cultivating healthy workplaces is a critical aspect of comprehensive worksite health promotion. The influence of healthy workplace exposures on employee health outcomes warrants research attention. To date, it is unknown if nature contact in the workplace is related to employee stress and health. This study was designed to examine the effects of nature contact experienced at work on employee stress and health. Methods. Office staff at a southeastern university (n=503, 30% response rate) participated in the cross-sectional study. We used a 16-item workplace environment questionnaire, the Nature Contact Questionnaire, to comprehensively measure, for the first time, nature contact at work. The Perceived Stress Questionnaire and 13 established health and behavioral items assessed the dependent variables, general perceived stress, stress-related health behaviors, and stress-related health outcomes. Results. There was a significant, negative association between nature contact and stress and nature contact and general health complaints. The results indicate that as workday nature contact increased, perceived stress and generalized health complaints decreased. Conclusions. The findings suggest that nature contact is a healthy workplace exposure. Increasing nature contact at work may offer a simple population-based approach to enhance workplace health promotion efforts. Future researchers should test the efficacy of nature-contact workplace stress interventions.

Is there a misplaced focus on AmED? Associations between caffeine mixers and bar patron intoxication

BACKGROUND Previous research on alcohol mixed with energy drinks (AmED) suffers from measurement problems. Missing from the research literature are studies that assess caffeine-alcohol co-ingestion in natural drinking environments. METHODS This field study collected data in a U.S. college bar district from 328 randomly selected patrons. Anonymous data were obtained from face-to-face interviews and self-administered surveys, and from breath tests. RESULTS Cola-caffeinated alcoholic beverage consumers left bars in a more highly intoxicated state than those who consumed alcohol only. There was no significant difference between the intoxication level of the AmED group and the cola-caffeinated alcoholic beverage group. Results from a multivariate regression model indicated that quantity of caffeinated alcoholic beverage consumption had a significant, positive association with bar patron intoxication after adjusting for potential confounders. CONCLUSIONS Findings indicate that caffeine may have a dose-dependent relationship with alcohol intoxication in the bar/nightclub setting. In addition, results revealed that cola-caffeinated alcoholic drinks may pose similar levels of risk to bar patrons as those associated with AmED beverage consumption. Product labeling requirements about alcohol risks may need to be extended not only to energy drinks, but to caffeinated soft drinks as well.

Efficacy of a Brief Image-Based Multiple-Behavior Intervention for College Students

BackgroundEpidemiologic data indicate most adolescents and adults experience multiple, simultaneous risk behaviors.PurposeThe purpose of this study is to examine the efficacy of a brief image-based multiple-behavior intervention (MBI) for college students.MethodsA total of 303 college students were randomly assigned to: (1) a brief MBI or (2) a standard care control, with a 3-month postintervention follow-up.ResultsOmnibus treatment by time multivariate analysis of variance interactions were significant for three of six behavior groupings, with improvements for college students receiving the brief MBI on alcohol consumption behaviors, F(6, 261) = 2.73, p = 0.01, marijuana-use behaviors, F(4, 278) = 3.18, p = 0.01, and health-related quality of life, F(5, 277) = 2.80, p = 0.02, but not cigarette use, exercise, and nutrition behaviors. Participants receiving the brief MBI also got more sleep, F(1, 281) = 9.49, p = 0.00, than those in the standard care control.ConclusionsA brief image-based multiple-behavior intervention may be useful in influencing a number of critical health habits and health-related quality-of-life indicators of college students.

Are effects from a brief multiple behavior intervention for college students sustained over time

OBJECTIVE This study examined whether 3-month outcomes of a brief image-based multiple behavior intervention on health habits and health-related quality of life of college students were sustained at 12-month follow-up without further intervention. METHODS A randomized control trial was conducted with 303 undergraduates attending a public university in southeastern US. Participants were randomized to receive either a brief intervention or usual care control, with baseline, 3-month, and 12-month data collected during fall of 2007. RESULTS A significant omnibus MANOVA interaction effect was found for health-related quality of life, p=0.01, with univariate interaction effects showing fewer days of poor spiritual health, social health, and restricted recent activity, ps<0.05, for those receiving the brief intervention. Significant group by time interaction effects were found for driving after drinking, p=0.04, and moderate exercise, p=0.04, in favor of the brief intervention. Effect sizes typically increased over time and were small except for moderate size effects for social health-related quality of life. CONCLUSION This study found that 3-month outcomes from a brief image-based multiple behavior intervention for college students were partially sustained at 12-month follow-up.

Guidelines for Designing a Web-Delivered College Health Risk Behavior Survey: Lessons Learned From the University of Florida Health Behavior Survey

Collecting health-risk behavior data from college students is a Web survey research application with extraordinary potential that has implications for individual schools and for the next National College Health Risk Behavior Survey. Recent evidence suggests that it is now feasible to collect health-risk behavior data from college students using the Web. This article describes the eight steps used in the 1999 University of Florida Health Behavior Survey that demonstrated the feasibility of the Web to collect health-risk behavior data from undergraduates. Practical issues researchers should consider when conducting Web-delivered survey research also are presented. Information in this article can be used by college and university health survey researchers and student health service administrators to plan and conduct their own health-risk behavior Web-delivered survey, and to develop an electronic college health-risk behavior surveillance system for their schools.

Covariates of alcohol consumption among career firefighters

BACKGROUND Little is known about rates of alcohol consumption in career firefighters. AIMS To assess the quantity and frequency of alcohol consumption among career firefighters and the covariates that influence consumption levels. METHODS A convenience sample of career firefighters completed an online, self-administered, health assessment survey. Hierarchical binary logistic regression assessed the ability of several covariates to predict binge drinking status. RESULTS The majority of the sample (n = 160) consumed alcohol (89%), with approximately one-third (34%) having a drinking binge in the past 30 days. The regression model explained 13-18% of the variance in binge drinking status and correctly classified 71% of cases. Race (P < 0.05) and time of service (P < 0.01) were the only covariates that made a statistically significant contribution to the model. After controlling for other factors in the model, white respondents were ~4.5 times more likely to binge drink than non-white respondents (95% CI: 1.15-17.4). For each additional year of service, firefighters were 1.08 times less likely to binge drink (95% CI: 0.87-0.97). CONCLUSIONS Drinking levels observed in this study exceed those of the general adult population, including college students. Thus, it appears that firefighters represent an at-risk drinking group. Further investigations addressing reasons for alcohol use and abuse among firefighters are warranted. This study and subsequent research will provide information necessary for the development and testing of tailored interventions aimed at reducing firefighter alcohol consumption.

An Exploratory Study of Bar and Nightclub Expectancies

Objective: The authors identified the principal components of bar and nightclub expectancy in college students and the associations between these factors and the risk behavior of night-clubbing. Participants: A total of 4,384 undergraduates enrolled at a large, public university participated. Methods: In the first phase (July-September 2007), the authors collected preliminary data from a convenience sample. In the second phase (March 2008), the authors collected data from a separate probability sample. Results: A principal components analysis revealed 4 reliable and distinct expectancy factors. Regression analyses revealed that after adjusting for the effects of alcohol and demographic variables, expectancies explained a significant proportion of variance in bar/nightclub attendance. Different expectancy profiles distinguished high-frequency nightclubbers from the most common bar attendance practice and nonmonogamous nightclubbers from monogamous nightclubbers. Conclusions: From a developmental perspective, nightclubbing appears to assist young adults with establishing and maintaining social networks, romantic and sexual relationships, and collegiate acculturation.
