Communities mobilizing for change on alcohol: outcomes from a randomized community trial.

OBJECTIVE: Communities Mobilizing for Change on Alcohol (CMCA) was a randomized 15-community trial of a community organizing intervention designed to reduce the accessibility of alcoholic beverages to youths under the legal drinking age. METHOD: Data were collected at baseline before random assignment of communities to intervention or control condition, and again at follow-up after a 2.5-year intervention. Data collection included in-school surveys of twelfth graders, telephone surveys of 18- to 20-year-olds and alcohol merchants, and direct testing of the propensity of alcohol outlets to sell to young buyers. Analyses were based on mixed-model regression, used the community as the unit of assignment, took into account the nesting of individual respondents or alcohol outlets within each community, and controlled for relevant covariates. RESULTS: Results show that the CMCA intervention significantly and favorably affected both the behavior of 18- to 20-year-olds (effect size = 0.76, p<.01) and the practices of on-sale alcohol establishments (effect size = 1.18, p<.05), may have favorably affected the practices of off-sale alcohol establishments (effect size = 0.32, p = .08), but had little effect on younger adolescents. Alcohol merchants appear to have increased age-identification checking and reduced propensity to sell to minors. Eighteen- to 20-year-olds reduced their propensity to provide alcohol to other teens and were less likely to try to buy alcohol, drink in a bar or consume alcohol. CONCLUSIONS: Community organizing is a useful intervention approach for mobilizing communities for institutional and policy change to improve the health of the population.

Relationships between physician advice and tobacco and alcohol use during pregnancy.

INTRODUCTION: We sought to examine relationships between physician advice and use of tobacco and alcohol during pregnancy among 683 women in the upper Midwest. METHODS: Data on risk of substance use during pregnancy were analyzed using logistic regression analysis. RESULTS: A higher proportion of women used tobacco (34%) than alcohol (25%) during their most recent pregnancy. Women who received advice from a physician to abstain from alcohol reported a lower risk of smoking and drinking during pregnancy than women who did not receive such advice. Risk of smoking and drinking during pregnancy was also common among women who reported early onset of alcohol use. CONCLUSIONS: Results suggest that physician advice regarding alcohol use during pregnancy is protective against maternal smoking and drinking during pregnancy.

Drinking patterns and problems among African-Americans: recent findings.

The findings of recent research on drinking patterns and problems among African-Americans can be summarized as follows: (1) African-Americans report higher abstention rates than do whites; (2) African-Americans and whites report similar levels of frequent heavy drinking; (3) rates of heavy drinking have not declined at the same rate among African-American men and women as among white men; and (4) variables such as age, social class, church attendance, drinking norms, and avoidance coping may be important in understanding differences in drinking and drinking problem rates among African-Americans and whites. Limitations of the research are described and suggestions are made for possible directions for future research.

Alcohol-related problems among black, Hispanic and white men: the contribution of neighborhood poverty.

OBJECTIVE: We examined the cross-sectional relationships between race/ethnicity, neighborhood poverty and alcohol-related problems among black, Hispanic and white male drinkers. Test hypotheses were that black and Hispanic men living in more impoverished neighborhoods would report increased numbers of alcohol-related problems than comparable white men. METHOD: Study hypotheses were tested in a sample of 744 black, Hispanic and white men participating in the 1992 National Alcohol Follow-up Survey. Study hypotheses were analyzed using generalized linear model regression analysis. RESULTS: Neighborhood poverty had a greater effect on alcohol-related problems in black than in white men, partially supporting our hypothesis. Black men living in more impoverished neighborhoods reported greater numbers of alcohol-related problems than comparable white men; there were no race differences among more affluent men. Neighborhood poverty had little effect on alcohol-related problems in Hispanic men. CONCLUSIONS: Findings suggest that, giving unfavorable economic conditions, black men will report greater numbers of alcohol-related problems than comparable white men.

Environmental predictors of drinking and drinking-related problems in young adults.

We examined relationships among drinking norms, peer alcohol use, alcohol availability, drinking location, alcohol consumption, and drinking-related problems among young adult drinkers. The specific objectives of our study were to assess the relative contribution of normative and physical environmental factors to drinking and drinking consequences. Subjects were 3,095 young adults, aged eighteen to twenty years old who participated in the Communities Mobilizing for Change on Alcohol Project baseline survey. Alcohol consumption (i.e., number of drinks on the last occasion) and drinking consequences served as dependent variables. Multiple linear regression was used to identify predictors of alcohol consumption, and logistic regression was employed to identify predictors of drinking consequences. Drinking norms and peer alcohol use were positively related to alcohol consumption and to drinking consequences. Drinking in a public setting was positively related to alcohol consumption, but not to drinking-related problems. Findings suggest that policies and programs that alter the normative and physical environment surrounding drinking may reduce alcohol consumption and subsequent problems in young adults.

Predictors of increases in alcohol-related problems among black and white adults: results from the 1984 and 1992 National Alcohol Surveys.

We examined increases in self-reported alcohol-related problems among black and white adult drinkers using data from the 1984 and 1992 National Alcohol Surveys. The objectives of the study were to determine whether alcohol consumption, drinking norm, or socioeconomic status were related to increases in alcohol-related problems. Two types of self-reported alcohol-related problems were analyzed using regression methods: drinking consequences and alcohol dependence symptoms. Results indicated that increases in alcohol consumption were associated with increased drinking consequences for white men, but increased consumption had little affect for black men. Changes in drinking norms regarding non-social drinking were associated with increased in drinking consequences among black men, such norms showed little affect on drinking consequences for white men. Despite substantial increases in alcohol consumption among black women from 1984 to 1992, there were no significant racial/ethnic differences in drinking consequences or alcohol dependence symptoms among women. Changes in socioeconomic status were however related to increases in drinking consequences and alcohol dependence symptoms in women, but not in men. Findings suggest that liberal drinking norms may have greater long term consequences for black than white men. Socioeconomic status, on the other hand, may have greater explanatory power in predicting increases in alcohol-related problems in women than in men.

Why and in what context adolescents obtain alcohol from adults: a pilot study.

Four focus groups involving 26 male and female high school seniors were conducted to provide insight into the context and settings in which alcohol is provided to youth, and why some youth choose certain sources of alcohol over others. Adults over the age of 21 years were the most common source of alcohol used by participants. Participants believe that it was less risky to ask an older adult to purchase alcohol than to attempt to buy it themselves. Few restrictions were placed on youth when alcohol was provided by an older adult. Youth may seek certain alcohol sources when they perceive that alcohol is available and risks of obtaining it are low.

Relationships among alcohol availability, drinking location, alcohol consumption, and drinking problems in adolescents.

We examined relationships among perceived alcohol availability, drinking location, alcohol consumption, and drinking problems. Subjects were 3,372 adolescent drinkers, ages 16-18, who participated in the Communities Mobilizing for Change on Alcohol Project baseline survey. Mixed-model regression was employed to identify predictors of alcohol consumption and drinking consequences. Perceived alcohol availability was significantly associated with higher levels of alcohol consumption for males. Drinking in a public location with higher levels of alcohol consumption for females. Results underscore the importance of youth alcohol assessibility.

Content analysis of coverage of alcohol control policy issues in black-oriented and mainstream newspapers in the U.S.

We conducted a content analysis of alcohol control policy issues in Black-oriented and mainstream newspapers in the United States from 1993 to 1995, using computerized content analysis methods. The specific purpose of our study was to compare differences in coverage of alcohol control policy issues in Black-oriented and mainstream newspapers. Fifteen Black-oriented and 12 mainstream newspapers were selected and analyzed. The number of policy paragraphs per year and the number of paragraphs in different policy thematic categories per year were examined. Regional differences in coverage of alcohol policy themes were examined for selected policies in mainstream newspapers. We found more similarities than differences in coverage of alcohol policy issues in Black-oriented and mainstream newspapers. Limiting the marketing/advertising and promotion of alcohol products was the most widely covered alcohol control policy issue over the three-year period in both Black-oriented media and mainstream newspapers. There were some important differences in coverage of alcohol policy issues. While economic alcohol policy issues were covered extensively in mainstream newspapers, these issues received far less attention in Black-oriented newspapers. Findings suggest that certain alcohol control policies may have less salience in African-American communities than in other communities.

Blood pressure in young blacks and whites: relevance of obesity and lifestyle factors in determining differences. The CARDIA Study. Coronary Artery Risk Development in Young Adults.

BACKGROUND: Middle-aged black men and women have higher blood pressure, on average, than whites. However, this pattern is inconsistent in children and adolescents. This study explores how differences in lifestyle factors in young adulthood may influence blood pressure patterns in the two races. METHODS AND RESULTS: The Coronary Artery Risk Development in Young Adults (CARDIA) study is an ongoing collaborative investigation of lifestyle and the evolution of cardiovascular disease risk factors in a random sample of young adults ages 18 to 30 years at baseline (1985 to 1986). Data from four examinations over 7 years were analyzed with the use of a method that simultaneously examined cross-sectional and longitudinal relationships of lifestyle factors and blood pressure. This study included 1154 black women, 853 black men, 1126 white women, and 1013 white men. Blacks had higher systolic blood pressure and diastolic blood pressure than whites at every examination. Racial differences were much greater in women than in men and increased over time. Within each sex-race group, average diastolic blood pressure over four examinations was positively associated with baseline age, body mass index, and alcohol intake and negatively associated with physical activity, cigarette use, and intake of potassium and protein. Longitudinal change in diastolic blood pressure was positively associated with changes in body mass index and alcohol intake. After adjustment for obesity and other lifestyle factors, black-white diastolic blood pressure differences were reduced substantially: 21% to 75% for men and 49% to 129% for women. Results for systolic blood pressure were similar. CONCLUSIONS: Differences in obesity and other lifestyle factors in young adults largely explain the higher baseline blood pressure and greater increase over time of blacks relative to whites.

Relationships between depressive symptoms, anxiety, alcohol consumption, and blood pressure: results from the CARDIA Study. Coronary Artery Risk Development in Young Adults Study.

OBJECTIVES: We examined cross-sectional relationships among depressive symptoms, anxiety, alcohol intake, and blood pressure. Test hypotheses were that: (1) alcohol intake, depressive symptoms, and anxiety would be positively related to blood pressure; (2) depressive symptoms and anxiety would have a stronger association with alcohol intake in Blacks than in Whites; and (3) adjustment for differences in depressive symptoms, anxiety, and alcohol intake would reduce Black-White blood pressure differences. METHODS: Study hypotheses were tested in a sample of 4,352 Black and White adults, participating in the CARDIA study. Hypotheses were tested using multiple linear regression. RESULTS: Alcohol intake was positively related to systolic (p = 0.0001) and diastolic (p = 0.0004) blood pressure in men, but not in women. Depressive symptoms and anxiety were unrelated to blood pressure. The relationship between alcohol intake and depressive symptoms differed by race/ethnicity in men (p = 0.0719) and in women (p = 0.0002). Alcohol intake increased with increasing levels of depressive symptoms, but the increase was greater in Blacks than in Whites. After accounting for alcohol intake, body mass index, and other variables, Black-White blood pressure differences were reduced in men, but not in women; most of the reduction was caused by body mass index. CONCLUSIONS: Blacks may respond differently than Whites to psychological distress.

Sources of alcohol for underage drinkers.

OBJECTIVE: We assessed the extent to which various sources of alcoholic beverages are used by early, middle and older teenagers, the extent to which teenagers perceive alcohol to be available from different sources and factors related to use of alternative sources. METHOD: Ninth graders (n = 2,269), twelfth graders (n = 2,377) and youth aged 18-20 (n = 1,738) were surveyed in 15 upper-midwestern communities using a nested cross-sectional design. Analyses were based on mixed-model regressions, with both the individual and community treated as random effects, taking into account the intraclass correlation for each dependent variable. Analyses focused on current (last 30 day) drinkers to avoid recall bias for drinking events in the distant past. RESULTS: A person aged 21 or over was the most common source of alcohol for current drinkers in all three age groups; 46% of 9th graders, 60% of 12th graders and 68% of those aged 18-20 obtained alcohol from a person age 21 or older for their last drinking occasion. A person under age 21 was the second most prevalent source for 9th and 12th graders (29% of each group obtained alcohol from someone under age 21 for their last drinking occasion). A commercial outlet was the second most prevalent source for those aged 18-20 (14% obtained alcohol directly from an outlet for their last drinking occasion). CONCLUSIONS: Perceived availability, binge drinking and several demographic characteristics were independently related to source of alcohol used, and age interacted with several factors in predicting source of alcohol. We conclude that increased attention to sources of alcohol used by youths would facilitate efforts to reduce underage drinking.

Measurement of alcohol and tobacco availability to underage students.

Communities Mobilizing for Change on Alcohol (CMCA) and Tobacco Policy Options for Prevention (TPOP) are randomized multicommunity trials designed to reduce the availability of alcohol (CMCA) and tobacco (TPOP) products to underage youth. We assessed the test-retest reliability and internal consistency of perceived availability measures developed for surveys of middle and high school students. Two questionnaires were administered twice, each to separate student populations (CMCA: 9th graders; TPOP; 8th graders) 21 to 26 days apart. A total of 111 (CMCA) and 70 (TPOP) subjects participated at both times (participation rate of 93.3% and 84.3%, respectively). There were no statistically significant differences in the distribution of demographic variables, alcohol or tobacco use variables, or availability variables across administrations. The scales assessing perceived access to alcohol or tobacco had high internal consistency (Cronbach's alpha of 0.84 for alcohol and 0.77 for tobacco), but moderate to low test-retest correlations (0.58 and 0.13, respectively). Single-item measures of sources of alcohol and tobacco and reported buy attempts also had moderate to low test-retest correlates (0.10-0.65). We recommend that items assessing tobacco and alcohol availability to underage youth be further developed.

Occupational attainment, smoking, alcohol intake, and marijuana use: ethnic-gender differences in the CARDIA study.

OBJECTIVES: To evaluate the prospective interrelationship of smoking, alcohol intake, marijuana use, and educational and occupational attainment of Black and White young adults. METHODS: Logistic or mixed model linear regression were used to evaluate relationships between self-reported substance use, ethnicity, gender, college graduation, and four measures of occupational attainment. RESULTS: College graduation in the next 10 years was negatively associated with smoking and marijuana use, but not daily alcohol consumption in all ethnic and gender groups. In Whites, marijuana use was associated with less prestigious occupations and lower family income, while smoking was unrelated and moderate daily drinking was positively associated. In Blacks, marijuana use was generally unrelated to occupational measures, while smoking and daily alcohol consumption were negatively associated. CONCLUSIONS: Relationships between smoking, marijuana use, daily drinking, and occupational attainment were not universally negative in this age group. Substance use, particularly smoking, is associated with reduced occupational attainment in Blacks compared with Whites after considering sociodemographic factors potentially limiting educational progression and occupational attainment.

Qualitative assessment of training programs for alcohol servers and establishment managers.

OBJECTIVE: In an attempt to reduce the societal burden associated with alcohol-related problems such as underage drinking and drunk driving, some local communities and state governments mandate training programs for employees of establishments that serve or sell alcoholic beverages. This study was designed to assess the available training programs for employees and managers and to identify states that either mandate training programs or encourage them by reducing establishments' legal liability. METHODS: Training programs were identified through the Internet, key informants, and the research literature. Three researchers independently rated each of 22 local and national programs across 10 categories. In addition, the authors surveyed alcoholic beverage control agencies and legislative research bureaus in the 50 U.S. states. RESULTS: The results show that training programs are not standardized and vary widely in content, use of behavior change methods, and production quality. Most programs targeted waitstaff and bartenders. Only one program exclusively targeted owners and managers. CONCLUSIONS: National standards must be developed for training programs for servers, managers, and owners.
