Project description:AimTo quantify the trends in frequent and occasional cannabis vaping, demographic differences and concurrent nicotine and alcohol use.DesignObservational study. Survey-weighted multinomial logistic regression models assessed trends and disparities in past 30-day cannabis use. Trends were assessed overall and by sex, race/ethnicity, parental education and urbanicity. Multinomial logistic regression models also estimated associations of cannabis use (none, use without vaping, use with vaping) with past 2-week binge drinking and past 30-day nicotine/tobacco use.SettingUnited States, 2017-19.ParticipantsParticipants in the national Monitoring the Future (n = 51 052) survey.MeasurementsPast 30-day frequent cannabis use (six or more times/30 days) and past 30-day occasional use (one to five times/30 days), with and without vaping.FindingsPast 30-day frequent cannabis use with vaping and occasional use with vaping rose from 2017 to 2019. Past 30-day frequent and occasional cannabis use without vaping declined. Certain groups, such as Hispanic/Latino or lower socio-economic status adolescents, experienced particularly notable increases in frequent cannabis use with vaping (e.g. prevalence among Hispanic/Latino adolescents). Adolescents who reported smoking and vaping nicotine, and 10+ occasions of binge drinking, were 42.28 [95% confidence interval (CI) = 33.14-53.93] and 10.09 (95% CI = 4.51-22.53) times more likely to report past 30-day cannabis use with vaping, respectively, compared with no use.DiscussionCannabis use without vaping appears to be declining among adolescents in the United States, while cannabis use with vaping is accelerating; frequent cannabis vaping is especially increasing, with consistent increases across almost all adolescent demographic groups. Cannabis use among US adolescents remains highly associated with other substance use.

Project description:ImportanceUS adolescent nicotine vaping increased at a record pace from 2017 to 2019, prompting new national policies to reduce access to flavors of vaping products preferred by youth.ObjectiveTo estimate prevalence, perceived harm, and accessibility of nicotine vaping products among US adolescents from 2017 to 2020.Design, setting, and participantsThis survey study includes data from Monitoring the Future, which conducted annual, cross-sectional, school-based, nationally representative surveys from 2017 to 2020 of 10th- and 12th-grade students (results pooled grades, n = 94 320) about vaping and other topics.Main outcomes and measuresPrevalence of self-reported nicotine vaping; vaping brand and flavor used most often; perceived risk of nicotine vaping; and perceived ease of getting vaping devices, nicotine solutions for vaping, and flavored solutions.ResultsIn 2020, Monitoring the Future surveyed 8660 students in 10th and 12th grade, of whom 50.6% (95% CI, 47%-54%) were female, 13% (95% CI, 8%-21%) were non-Hispanic Black, 29% (95% CI, 21%-40%) were Hispanic, and 53% (95% CI, 42%-63%) were non-Hispanic White. Nicotine vaping prevalence in 2020 was 22% (95% CI, 19%-25%) for past 30-day use, 32% (95% CI, 28%-37%) for past 12-month use, and 41% (95% CI, 37%-46%) for lifetime use; these levels did not significantly change from 2019. Daily nicotine vaping (use on ≥20 days of the last 30 days) significantly declined from 9% (95% CI, 8%-10%) to 7% (95% CI, 6%-9%) over 2019 to 2020. JUUL brand prevalence in the past 30 days decreased from 20% (95% CI, 18%-22%) in 2019 to 13% (95% CI, 11%-15%) in 2020, while use of other brands increased. Among youth who vaped in the past 30 days in 2020, the most often used flavor was fruit at 59% (95% CI, 55%-63%), followed by mint at 27% (95% CI, 24%-30%) and menthol at 7% (95% CI, 5%-9%); significantly fewer reported easy access to vaping devices and nicotine solutions compared with 2019; and 80% (95% CI, 75%-84%) reported they could easily get a vaping flavor other than tobacco or menthol. Among all youth, perceived risk of both occasional and regular nicotine vaping increased from 2019 to 2020.Conclusions and relevanceIncreasing US adolescent nicotine vaping trends from 2017 to 2019 halted in 2020, including a decline in daily vaping. Decreases in perceived accessibility of some vaping products, as well as increases in perceived risk of nicotine vaping, occurred from 2019 to 2020. Yet, adolescent nicotine vaping remains highly prevalent, flavors remain highly accessible, and declines in JUUL use were countered by increased use of other brands.

Project description:BackgroundThe world has made considerable progress in the reduction of adolescent maternity and early marriage. However, this progress has been uneven, with many countries finding themselves far from achieving the Sustainable Development Goals in this dimension. We assessed levels and trends over time in adolescent marriage and maternity prevalence within the West and Central African region as well as their correlation with select macro-level indicators for income and social institutions.MethodsWe estimated country-specific prevalence rates using survey data (pooled cross-sectional) conducted between 1986 and 2017. The pooled sample provides information on 262 721 adolescent girls between the ages of 15 and 19. We assessed the relative country-level trends by comparing prevalence rates from the first and latest available survey in each country. We further analyzed regional trends by country income group (low- and middle-income) and examined the association of prevalence rates with measurements of gender discrimination and social institutions at the country-level. Estimations were conducted using survey weights and country-specific weights for population shares in the pooled sample.ResultsPrevalence of adolescent maternity declined from 30.1 percent (95% confidence interval (CI) = 29.6%-32.2%) in the 1990s, to 28.7 percent (95% CI = 27.9%-29.6%) in the 2000s and 26.2 percent (95% CI = 25.4%-27.1%) in the 2010s. Adolescent marriage rates decreased from 37.3 percent (95% CI = 35.5%-39.1%) in the 1990s to 27.5 percent (95% CI = 26.5%-28.6%) in the 2000s, and to 24.9 percent (95% CI = 24.1%-25.7%) in the 2010s. Between 1986 and 2017, adolescent marriage decreased in all countries except for the Central African Republic (with a rise from 39% to 55%) and Niger (56% to 61%). The prevalence of adolescent maternity decreased in all but three countries: Congo, Dem. Rep. (25% to 37%), Niger (36% to 40%), and the Central African Republic (36% to 49%). When grouped by income level, the prevalence was 8 percentage points higher in low-income countries than in middle-income countries in both outcomes. We did not establish any statisticly significant association between adolescent marriage and maternity with country-level measures of discrimination against women. However, we found evidence of an association between specific legal measures of protection against early marriage and lower prevalence rates for both early marriage and maternity.ConclusionsDespite considerable progress in the reduction of adolescent maternity and marriage over the last 30 years, current levels of both indicators remain overall high in the WCA region, with high heterogeneity across individual countries. Countries with higher income level and higher standard in legal protection of young girls perform consistently better on both indicators. The prevalence rates of adolescent marriage and maternity reversed over the course of three decades, so that nowadays adolescent maternity rates exceed adolescent marriage rates in most countries. Further research is needed to understand the weak or non-existent association between adolescent marriage and maternity with gender discrimination and social institutions.

Project description:Background and aimsAccording to recent criticism, survey-based measures of adolescent psychosomatic complaints have poor content validity insofar as they conflate trivial with severe complaints. It is argued that this means that estimates of prevalence and trends in complaints may reflect trivial complaints that are not indicators of health problems. In this study, two observable implications of this criticism were investigated: (a) that self-reported psychosomatic complaints should have a bimodal distribution; and (b) that the increase in complaints over time should be of approximately equal size throughout the distribution of complaints.MethodsThree decades (1985/1986-2017/2018) of repeated cross-sectional data from the Swedish Health Behaviour in School-aged Children survey were used. Psychosomatic complaints were measured using the screening instrument Health Behaviour in School-aged Children symptom checklist. Histograms, bar charts and quantile regression models were used for the analysis.Results and conclusions

Project description:Since 2016, a series of horrific acts motivated by antisemitism appear to have caused a fundamental shift in the prevalence of antisemitism in the United States. Little is known, however, about how the events during this time have affected the day-to-day experiences and concerns of American Jews. Using repeated cross-sectional data from surveys of Jewish young adults who applied to Birthright Israel, this paper analyzes recent trends in Jewish young adults' experiences and perceptions of antisemitism. Despite the high-profile incidents during this period, there is no evidence of a major increase in experiences of antisemitic harassment among Jewish young adults-either on or off campus-between 2017 and 2019. At the same time, data show a substantial increase in concerns among young Jews about antisemitism in the United States and on college campuses, with concerns about antisemitism in the United States (but not on campus) being especially concentrated among liberal Jews. These results suggest that Jewish concerns about antisemitism are linked to broader views about the climate for marginalized populations in the United States. They also point to growing Jewish anxieties over violence, safety, and acceptance in the United States. In an era of widely disseminated antisemitic conspiracy theories, even young Jews who have no first-hand experience of antisemitic harassment have become concerned.Supplementary informationThe online version of this article (10.1007/s12397-021-09354-6) contains supplementary material, which is available to authorized users.

Project description:PurposeAlthough estimates of heroin and injection drug use (IDU) among U.S. adolescents have remained low and stable, national data may mask local variation in use. Adolescent use may be higher in urban areas, many of which have historically high rates of heroin use and IDU. We investigate trends in heroin use and IDU among 9th-12th grade students in major urban centers in the U.S.MethodsWe used local Youth Risk Behavior Survey data from all large, urban school districts (n = 9) with at least 5 years of weighted, publicly available data. We used time series mean estimation to estimate the prevalence of heroin use and IDU among high school students from 1999 to 2017 and used logistic regression to test for linear and quadratic trends.ResultsWe observed statistically significant linear increases in (1) lifetime heroin use in New York (β = .43, 1%-3.9%), Chicago (β = .15, 3.1%-4.6%), and Milwaukee (β = .35, 2.8%-7.4%); and (2) lifetime IDU in New York (β = .34, .8%-2.7%), Orange County (β = .17, 2.2%-3.5%), and Miami-Dade County (β = .16, 2.7%-3.9%). Only San Bernardino experienced significant decreases in heroin use (β = -.34, 4.6%-1.6%) and IDU (β = -.20, 2.5%-1.9%) over the time period.ConclusionsIn contrast to national trends, the prevalence of heroin use is increasing among adolescents in certain urban centers in the U.S. Our results illustrate that national averages mask local variation in adolescent heroin use. Further research with locally representative samples is needed to inform public health policy and practice, especially in cities where heroin problems have been historically endemic and continue to rise.
