Fraternity membership and binge drinking

This paper examines the relationship that social fraternity and sorority membership has with binge drinking incidence and frequency among 18-24 year old full-time 4-year college students who participated in the 1995 National College Health Risk Behavior Survey. To net out unobserved heterogeneity, several measures of situational and total alcohol use are entered into the regressions as explanatory variables. Fraternity membership coefficients are substantially reduced in size, but remain large and highly significant, suggesting a causal effect on binge drinking. Otherwise, the estimates identify idiosyncratic selection into fraternities and binge drinking across students with similar overall drinking profiles. Particularly notable is that behavior by underage students appears to drive the relationship.     

Modeling continuous response variables using ordinal regression

We study the application of a widely used ordinal regression model, the cumulative probability model (CPM), for continuous outcomes. Such models are attractive for the analysis of continuous response variables because they are invariant to any monotonic transformation of the outcome and because they directly model the cumulative distribution function from which summaries such as expectations and quantiles can easily be derived. Such models can also readily handle mixed type distributions. We describe the motivation, estimation, inference, model assumptions, and diagnostics. We demonstrate that CPMs applied to continuous outcomes are semiparametric transformation models. Extensive simulations are performed to investigate the finite sample performance of these models. We find that properly specified CPMs generally have good finite sample performance with moderate sample sizes, but that bias may occur when the sample size is small. Cumulative probability models are fairly robust to minor or moderate link function misspecification in our simulations. For certain purposes, the CPMs are more efficient than other models. We illustrate their application, with model diagnostics, in a study of the treatment of HIV. CD4 cell count and viral load 6 months after the initiation of antiretroviral therapy are modeled using CPMs; both variables typically require transformations, and viral load has a large proportion of measurements below a detection limit.     

Binge eating and binge drinking: an integrative review

The primary goal of this review is to provide a framework for understanding two highly overlapping behaviors: binge eating and binge drinking. Research is presented that suggests binge eating and drinking behaviors may share several important features, including personality correlates such as neuroticism and urgency, as well as affective characteristics, such as elevated levels of negative affect. Additionally, the review describes common explanatory models, which are helpful in terms of their potential to link these common features to the functions of, or reasons why individuals engage in, binge eating and drinking behaviors. Implications for understanding potentially common etiological pathways and development of interventions designed to target multiple behaviors are discussed.     

Personality,attitudinal and behavioral risk profiles of young female binge drinkers and smokers

PurposeAnalyses were conducted to identify personality, attitudinal and behavioral correlates of binge drinking and smoking among adolescent girls and young women, a population whose substance use attitudes and behaviors have received only limited attention in the literature.MethodsA nationally representative sample of girls and young women (n = 929) from three age cohorts completed a telephone interview assessing various personality, attitudinal, and behavioral characteristics. Respondents were categorized into four groups based on self-reported binge drinking and smoking (binge drinker/nonsmoker, smoker/non-binge drinker, binge drinker/smoker, or non-binge drinker/nonsmoker) and were assessed on a number of variables, including self-monitoring, depressive symptoms, coping style, religiosity/spirituality, popularity, dieting behavior, and smoking- and alcohol-related expectations. Univariate and multiple regression analyses were conducted to identify characteristics that best describe each of these types of substance users.ResultsRisk profiles varied across the groups. Girls and young women who binge drank but did not smoke were more likely to be high self-monitors, to engage in disordered dieting, and to believe drinking provided an excuse to act with less inhibition. Those who smoked but did not binge drink were more likely to report depressive symptoms. Those who binge drank and smoked were more likely to be popular and to report depressive symptoms. Certain forms of avoidant coping and low religiosity were associated with all three types of substance use.ConclusionUnderstanding the risk profiles of girls and young women who engage in specific forms of substance use can facilitate the identification of those at risk and the development of more targeted and effective prevention programs and interventions.     

One-year drinking history and mortality

The one-year drinking history of 94 men was recorded by recurrent interviews (mean: 20 per person). The cohort was followed for 18.3 years; during that time, 13 men died. Cox's proportional hazards survival models including age and social class as confounders, indicated that mortality was significantly associated with total annual alcohol consumption, frequency of drinking, and frequency of intoxicating drinking. Estimates of risk of death for various consumption levels are presented: For having 10 drinks (each containing 12 grams of pure ethanol) a week vs one drink a week, the estimated relative risk of death (95% confidence limits in parentheses) was 2.3 (1.6-3.3). For being intoxicated once a week vs no intoxications at all during one year the respective risk was 2.1 (1.3-3.1). The risk estimates for the frequency of intoxication were found to be higher than those in an earlier study using single interview data on drinking. This suggests that more accurate measurement of alcohol consumption may yield higher risk of death estimates than found in studies based on single interview data on alcohol.     

The regional geography of alcohol consumption in England: Comparing drinking frequency and binge drinking

Alcohol consumption frequency and volume are known to be related to health problems among drinkers. Most of the existing literature that analyses regional variation in drinking behaviour uses measures of consumption that relate only to volume, such as ’binge drinking’. This study compares the regional association of alcohol consumption using measures of drinking frequency (daily drinking) and volume (binge drinking) using a nationally representative sample of residents using the Health Survey for England, 2011–2013. Results suggest the presence of two differentiated drinking patterns with relevant policy implications. We find that people in northern regions are more likely to binge drink, whereas people in southern regions are more likely to drink on most days. Regression analysis shows that regional variation in binge drinking remains strong when taking into account individual and neighbourhood level controls. The findings provide support for regional targeting of interventions that aim to reduce the frequency as well as volume of drinking.     

The state sets the rate: the relationship among state-specific college binge drinking, state binge drinking rates, and selected state alcohol control policies

OBJECTIVES: We assessed the relationship between college binge drinking, binge drinking in the general population, and selected alcohol control policies. METHODS: We analyzed binge drinking rates from 2 national surveys, the Harvard School of Public Health College Alcohol Study and the Centers for Disease Control and Prevention's Behavioral Risk Factor Surveillance System. Binge drinking data were linked to a summary measure of 7 salient alcohol control policies and a rating of resources devoted to law enforcement. RESULTS: State-level college and adult binge drinking rates were strongly correlated (Pearson correlation coefficient=0.43; P<.01). Attending college in states with the lowest binge drinking rates (adjusted odds ratio [OR]=0.63; 95% confidence interval [CI]=0.41, 0.97) and presence of more stringent alcohol control policies (adjusted OR=0.57; 95% CI=0.33, 0.97) were independent predictors of student binge drinking, after adjusting for state law enforcement and individual-, college-, and state-level covariates. CONCLUSIONS: State of residence is a predictor of binge drinking by college students. State-level alcohol control policies may help reduce binge drinking among college students and in the general population.     

Same-sex attraction, drug injection and binge drinking among Australian adolescents

OBJECTIVE: To document the prevalence of same-sex attraction among students in years 10 and 12 in Australian Government high schools and to assess the association between same-sex attraction, binge drinking and drug injection. METHOD: Cross-section survey by anonymous, self-administered questionnaire of 3,387 students in Years 10 and 12 of the Government school system in Australia. RESULTS: Approximately 6% of respondents reported being currently attracted to members of their own sex. Being attracted to members of the same-sex was associated with more frequent binge drinking among boys and girls, and a three- to four-fold increase in the likelihood of reporting injecting drug use both over the lifetime and within the previous 12 months. CONCLUSIONS: Adolescents attracted to members of the same-sex report engaging in elevated levels of health-limiting behaviours. There is an urgent need for further research to document the reasons for this. It is recommended that health promotion activities directed at moderating young people's drug and alcohol practices explicitly acknowledge the over-representation of same-sex attracted young people in their target audience.     

Parental and school correlates of binge drinking among middle school students

OBJECTIVES: We examined the prevalence and dynamics of binge drinking among middle school students. METHODS: We analyzed data from the National Longitudinal Study of Adolescent Health. The sample was composed of approximately 5300 seventh-and eighth-grade students who were interviewed at 2 points in time. RESULTS: Approximately 8% of seventh graders and 17% of eighth graders reported engaging in binge drinking during the past 12 months. These rates varied as a function of school characteristics. Low scores on the parenting variables-communication quality, use of reasoning, and control and supervision-and binge drinking during middle school also were predictive of binge drinking during high school. CONCLUSIONS: Binge drinking among middle school students is an important phenomenon that for many students forecasts future binge drinking during high school.     

Periconceptional binge drinking and acculturation among pregnant Latinas in New Mexico

Binge drinking during pregnancy might lead to the development of Fetal Alcohol Spectrum Disorders in the offspring. Latinas are often considered a low-risk group for alcohol abuse, although recent reports indicate that the prevalence of alcohol consumption in this group is increasing due to changing cultural norms. The predictors of alcohol consumption during pregnancy among Latinas are largely unknown. We explored predictors of periconceptional drinking among Latinas (n = 155) recruited into an ongoing cohort study at the University of New Mexico. Women were interviewed by a bilingual trained interviewer about any episodes of binge drinking (≥4 drinks/occasion) a month around their last menstrual period (LMP) and were administered a TWEAK questionnaire. Sociodemographic, lifestyle, and reproductive health characteristics were also ascertained. Predictors of binge drinking were identified by Chi-square test and logistic regression in univariate and multivariable analyses, respectively. Backward selection procedure was used to identify covariates that were independently associated with binge drinking in the final model. The mean age of participants was 27.0 ± 5.8 years and 69% were foreign born. In the entire sample, 17.4% of pregnant Latinas admitted at least one binge-drinking episode in the month around their LMP. Results of multivariate analysis indicate that Latinas born in the United States have a much greater risk of binge drinking in the periconceptional period (odds ratio [OR] = 3.2; 95% confidence interval [CI]: 1.2, 8.9) compared with foreign-born Latinas. Similarly, Latinas who primarily speak English at home were at much greater risk (OR = 3.6; 95% CI: 1.3, 10.5) compared with primarily Spanish-speaking women. No other variables were identified as significant predictors in multivariable models. Our results indicate that more acculturated Latinas are at much greater risk of binge drinking before conception and in early pregnancy compared with less acculturated Latinas. Culturally sensitive interventions should be developed to address risky alcohol consumption among Latinas of reproductive age.     

Correcting for measurement error in binary and continuous variables using replicates.

Measurement error in exposures and confounders leads to bias in regression coefficients. It is possible to adjust for this bias if true values or independent replicates are observed on a subsample. We extend a method suitable for quantitative variables to the situation where both binary and quantitative variables are present. Binary variables with independent replicates introduce two extra problems: (i) the error is correlated with the true value, and (ii) the measurement error probabilities are unidentified if only two replicates are available. We show that - under plausible assumptions - adjustment for error in binary confounders does not need to address these problems. The regression coefficient for a binary exposure is overadjusted if methods for continuous variables are used. Correct adjustment is possible either if three replicates are available, or if further assumptions can be made; otherwise, bounds can be put on the correctly adjusted value, and these bounds are reasonably close together if the exposure has prevalence near 0.5.     

Psychosocial variables associated with binge eating in obese males and females.

OBJECTIVE: This study tested a psychosocial model of binge eating symptoms in obese men and women. Predictor variables included depression, dietary restraint, self-esteem, weight cycling, history of teasing, body dissatisfaction, and neuroticism. METHOD: Participants (N = 808) completed a packet of self-report questionnaires. RESULTS: Weight cycling, teasing about weight and shape, body dissatisfaction, negative affect, and dietary restraint comprised the best fitting models (original and cross-validation) for binge eating in women and men. These variables explained 61-72% of the variance in symptoms of binge eating in the samples of men and 70% of the variance in the samples of women. Although the male and female models were mostly similar, notable differences between them were found. DISCUSSION: The variables that comprise these etiological models should be considered in the development of prevention programs for obese binge eaters. Longitudinal studies, however, are needed to examine these etiological paths and to test for causal relationships.     

The impact of drinking and drinking consequences on short-term employment outcomes in at-risk drinkers in six southern states

Alcohol use and misuse impose economic burdens, with over half the total costs estimated associated with lost productivity. Research on labor productivity and alcohol abuse has been limited by methodologic differences, making conclusions equivocal. This study employed two waves of data from a community probability sample of 658 at-risk drinkers. It analyzed the prospective impact of several measures of drinking and drinking consequences on the 6-month follow-up probability of not being employed and fewer weeks of employment if employed. Drinking seven drinks or more on an average drinking day significantly increased the likelihood of not working and, for those who were working, reduced weeks of employment. Thus, productivity benefits may accrue from developing treatments for at-risk drinkers, particularly interventions to reduce drinking.Dr Feng is now a Senior Marketing Analyst with Corning, Inc.     

School policies and binge drinking behaviours of school-aged children in Wales--a multilevel analysis

Research has highlighted increased and earlier alcohol consumption among young people. This study aims to explore whether the type of school alcohol policy employed is associated with the frequent binge drinking behaviours of adolescents, after adjusting for known demographic and social factors. Integrated cross-sectional data were used from Welsh school surveys that assess the health behaviours of adolescents and school health policies. Frequent binge drinking was more likely to occur among older pupils, those living with one parent and pupils from more affluent backgrounds. Frequent binge drinking was also associated with pupils who bullied others, those with greater peer involvement and who felt pressured by schoolwork. The results suggested that strong parental and school bonds were protective factors against frequent binge drinking as were greater life satisfaction. Pupils who were bullied were less likely to have frequently binge drank. There was some evidence to suggest that written school policies are associated with lower likelihood of frequent binge drinking, in particular among boys and pupils with lower school attachment. However, there is a need for greater understanding of the differential population influence of school alcohol polices and an evaluation of their effectiveness.
