Objectives. This study identified high school seniors at low, moderate, and high risk for cigarette use to examine changes in the prevalence of daily smoking within risk groups from 1976 to 1995. Methods. Data were taken from the Monitoring the Future Project's national surveys of high school seniors. Risk classification was based on grade- point average, truancy, nights out per week, and religious commitment. Logistic regression models were used to estimate trends for all seniors and separately for White (n = 244 221), African American (n = 41 005), and Hispanic (n = 18 457) male and female subgroups. Results. Risk group distribution (low=45%, moderate = 30%, high = 25%) changed little over time. Between 1976 and 1990, greater absolute declines in smoking occurred among high-risk students (17 percentage points) than among low-risk students (6 percentage points). Particularly large declines occurred among high-risk African Americans and Hispanics. Smoking increased in all risk groups in the 1990s. conclusions. Among high school seniors, a large part of the overall change in smoking occurred among high-risk youth. Policies and programs to reduce smoking among youth must have broad appeal, especially to those at the higher end of the risk spectrum. [ABSTRACT FROM AUTHOR]

Introduction: This study assessed the prevalence of current high-intensity drinking (i.e., having ten or more drinks in a row in the past 2 weeks) among national samples of U.S. eighth and tenth grade students (at modal ages 14 and 16 years, respectively).Methods: Data on high-intensity drinking were provided by 10,210 students participating in the nationally representative Monitoring the Future study in 2016, and analyzed in 2016-2017. Prevalence levels and interactions between grade and key covariates were estimated using procedures that adjusted for the Monitoring the Future study's complex sampling design.Results: Approximately 2% of adolescents reported current high-intensity drinking, with significant differences by grade (1.2% of eighth graders; 3.1% of tenth graders) and gender (1.7% female; 2.3% male). High-intensity drinking was significantly higher among eighth and tenth grade students who reported any cigarette or marijuana use than among students who reported never using either substance.Conclusions: A meaningful percentage of young adolescents in the U.S. engage in high-intensity drinking.

Objective: The study describes the most common reasons for using vaporizers (such as e-cigarettes) among US adolescents and investigates how reasons for use differ by grade, lifetime cigarette use, frequency of vaporizer use, gender, race/ethnicity, and parent education.Method: Data were collected from 4066 students in the 8th, 10th, and 12th grades in 2015 as part of the Monitoring the Future study, a cross-sectional and nationally representative US survey.Results: Common reasons for vaporizer use reported by respondents who had ever used a vaporizer were experimentation (53.0%), taste (37.2%), boredom (23.5%), having a good time (22.4%), and relaxation (21.6%). Reasons differed little across grades or parent education; reasons differed by lifetime use of regular cigarettes, frequency of vaping, gender, and race/ethnicity.Conclusions: Overall, results suggest that decisions to vape are based on curiosity, taste, and pleasure, rather than for reasons such as quitting regular cigarettes or substituting for regular cigarette smoking.

To demonstrate that intentions predict long-term future levels of smoking, irrespective of level of past smoking experience. A growing body of research suggests that intentions about future smoking might play an important role in addition to the influence of past smoking experience on the likelihood of smoking in future. Using logistic regression analyses, we assessed the relationship between baseline smoking experience and a firm intention ‘not to be smoking cigarettes 5 years from now’ with four outcome measures of smoking at follow-up: 30-day smoking at a 3/4- and 5/6-year follow-up and current established smoking (self-described regular smokers or former smokers who had smoked in the past 30 days) at a 3/4- and 5/6-year follow-up. US nationally representative samples of 12th graders who responded to the Monitoring the Future (MTF) survey from the years 1976 to 1993, inclusive. For these panels, we linked stage of smoking and intentions at 12th grade to follow-up measures of smoking collected at 3/4 years after baseline and 5/6 years after baseline. Analysis of 3/4-year follow-up data (weighted n = 4544) and 5/6-year follow-up data (weighted n = 3885) for both definitions of smoking outcome indicated that there was a dose–response relationship between levels of baseline smoking experience and the likelihood of future smoking. In addition, independent of baseline smoking experience, there was a statistically significant protective effect for a firm intention not to smoke in five year's time on future smoking behavior. The findings suggest that evaluative studies of tobacco control policies and programs might usefully employ smoking uptake categories that incorporate smoking intentions as early indicators of outcome.

Presents a study which examined differences in adolescents' use of tobacco, alcohol and illicit drugs by racial and ethnic groups. Methods; Results; Conclusions.

Objectives. The US armed forces adopted "zero tolerance" policies concerning illicit drug use in 1980 and later developed policies to discourage tobacco and alcohol abuse. This article examines drug use among young active-duty recruits both before and after enlistment, compared with non- military age-mates, and documents historical shifts in such drug use across 2 decades. Methods. Analyses employed longitudinal panel data from 20 nationally representative samples of high school seniors (cohorts of 1976-1995), each surveyed just before graduation and again within 2 years. Separate analyses for men (n = 12082) and women (n = 15 345) contrasted those who entered military service, college, and civilian employment. Results. Illicit drug use declined more among young military recruits than among their civilian counterparts. Analyses of male recruits at multiple time periods showed (1) declines in the prevalence of marijuana use and cocaine use after the initiation of routine military drug testing and (2) lower proportions of smokers of half a pack or more of cigarettes per day who entered service after the initiation of tobacco bans during basic training. conclusions. Recent military drug policies appear to deter illicit drug use among enlistees and discourage some smokers from enlisting. [ABSTRACT FROM AUTHOR]

Objective. We examined the relationship between state-level tobacco control expenditures and youth smoking prevalence and cigarette consumption. Methods. We estimated a 2-part model of cigarette demand using data from the 1991 through 2000 nationally representative surveys of 8th-, 10th-, and 12th-grade students as part of the Monitoring the Future project. Results. We found that real per capita expenditures on tobacco control had a negative and significant impact on youth smoking prevalence and on the average number of cigarettes smoked by smokers. Conclusions. Had states represented by the Monitoring the Future sample and the District of Columbia spent the minimum amount of money recommended by the Centers for Disease Control and Prevention, the prevalence of smoking among youths would have been between 3.3% and 13.5% lower than the rate we observed over this period.

Abstract: Background: This study uses large nationally representative samples of White, Black, Mexican American, Puerto Rican, Other Latina, Asian American, and American Indian 8th-grade girls to examine racial/ethnic differences and similarities in patterns, trends, and socioeconomic correlates of cigarette use. Methods: The data are drawn from the University of Michigan''s Monitoring the Future study. Prevalence and trend data (from 1991 to 2007) in girls’ cigarette use were examined by racial/ethnic subgroup. Logistic regression analyses were conducted to determine the extent to which socioeconomic factors predict girls’ cigarette use, and whether the relationships between socioeconomic status (SES) and smoking differed across racial/ethnic subgroup. Results: Cigarette use was highest among American Indian girls; at an intermediate level among Mexican American, Puerto Rican, Other Latinas, and White girls; and lowest among Black and Asian American girls. Trend data show that cigarette use has declined for all racial/ethnic subgroups, and that small but consistent racial/ethnic differences in girls’ cigarette use have persisted. Generally, girls who did not live in two-parent households, whose parents had lower levels of educational attainment, who attended lower SES schools, and who had more disposable income were more likely than their peers to smoke. That said, however, the relationships between smoking and parental education and school SES were, on average, stronger for White girls than for Black or Hispanic (Mexican American, Other Latina, Puerto Rican) girls. Conclusions: Future research should seek to understand the mechanisms by which low SES impacts smoking. [Copyright &y& Elsevier]
