Selection and socialization effects of fraternities and sororities on US college student substance use: a multi-cohort national longitudinal study

Aims  To examine how membership in fraternities and sororities relates to the prevalence and patterns of substance use in a national sample of full-time US college students. Design  Nationally representative probability samples of US high school seniors (modal age 18 years) were followed longitudinally across two follow-up waves during college (modal ages 19/20 and 21/22). Setting  Data were collected via self-administered questionnaires from US high school seniors and college students. Participants  The longitudinal sample consisted of 10 cohorts (senior years of 1988–97) made up of 5883 full-time undergraduate students, of whom 58% were women and 17% were active members of fraternities or sororities. Findings  Active members of fraternities and sororities had higher levels of heavy episodic drinking, annual marijuana use and current cigarette smoking than non-members at all three waves. Although members of fraternities reported higher levels than non-members of annual illicit drug use other than marijuana, no such differences existed between sorority members and non-members. Heavy episodic drinking and annual marijuana use increased significantly with age among members of fraternities or sororities relative to non-members, but there were no such differential changes for current cigarette use or annual illicit drug use other than marijuana. Conclusions  The present study provides strong evidence that higher rates of substance use among US college students who join fraternities and sororities predate their college attendance, and that membership in a fraternity or sorority is associated with considerably greater than average increases in heavy episodic drinking and annual marijuana use during college. These findings have important implications for prevention and intervention efforts aimed toward college students, especially members of fraternities and sororities.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71423/1/j.1360-0443.2005.01038.x.pd

Non-medical use of prescription stimulants among US college students: prevalence and correlates from a national survey

Aims  To examine the prevalence rates and correlates of non-medical use of prescription stimulants (Ritalin, Dexedrine or Adderall) among US college students in terms of student and college characteristics. Design  A self-administered mail survey. Setting  One hundred and nineteen nationally representative 4-year colleges in the United States. Participants  A representative sample of 10 904 randomly selected college students in 2001. Measurements  Self-reports of non-medical use of prescription stimulants and other substance use behaviors. Findings  The life-time prevalence of non-medical prescription stimulant use was 6.9%, past year prevalence was 4.1% and past month prevalence was 2.1%. Past year rates of non-medical use ranged from zero to 25% at individual colleges. Multivariate regression analyses indicated non-medical use was higher among college students who were male, white, members of fraternities and sororities and earned lower grade point averages. Rates were higher at colleges located in the north-eastern region of the US and colleges with more competitive admission standards. Non-medical prescription stimulant users were more likely to report use of alcohol, cigarettes, marijuana, ecstasy, cocaine and other risky behaviors. Conclusions  The findings of the present study provide evidence that non-medical use of prescription stimulants is more prevalent among particular subgroups of US college students and types of colleges. The non-medical use of prescription stimulants represents a high-risk behavior that should be monitored further and intervention efforts are needed to curb this form of drug use.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74786/1/j.1360-0443.2005.00944.x.pd

Consumo de drogas ilegales, apoyo familiar y factores relacionadosen estudiantes universitarios. Un estudio transversal basado en datosdel Proyecto uniHcos

Objective: To assess the prevalence of illegal drug use in college students on any previous occasion, duringthe previous year and the previous month, and to analyze the relationship between illegal drug use andfamily support and other factors.Methods: A cross-sectional study using data from students participating in the uniHcos project (n = 3767)was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives,stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent vari-ables were: family support, age, residence, and employment status. To determine the factors related todrug use multivariate logistic regression models stratified by gender were fitted.Results: Differences between men and women in prevalence of illegal drug use except non-prescriptionsedatives were observed. In both genders, less family support was associated with higher consumptionof all drugs, except depressants, and with polyconsumption. To be studying and looking for work wasrelated to cannabis and stimulant use and to polyconsumption among women, but only to cannabis useamong men.Conclusions: These results support the notion that the start of university studies is a particularly relevantstage in the onset of illegal drug use and its prevention, and that consumption may be especially associatedwith family support.Objetivo: Evaluar la prevalencia del consumo de drogas ilegales en estudiantes universitarios y analizarla relación entre dicho consumo, el apoyo familiar y otros factores.Método: Se realizó un dise?no transversal basado en datos de participantes en el proyecto uniHcos (n =3767). Se evaluaron la prevalencia y la edad de inicio del consumo de cannabis, tranquilizantes sin receta,estimulantes y depresores, y el policonsumo. Como variables independientes se consideraron el apoyofamiliar, la edad, la residencia y la situación laboral. Para la determinación de los factores asociados alconsumo de drogas se ajustaron modelos de regresión logística estratificados por sexo.Resultados: Se observaron diferencias entre hombres y mujeres en la prevalencia del consumo de todaslas drogas ilegales, excepto tranquilizantes sin receta. En ambos sexos, cuanto peor apoyo familiar, mayorconsumo de todas las drogas, excepto depresores y policonsumo. Encontrarse estudiando y buscandotrabajo se relacionó con el consumo de cannabis, estimulantes y policonsumo en las mujeres, y solo concannabis en los hombres.Conclusiones: Los resultados de este estudio aportan nueva evidencia a favor de que el inicio de la etapauniversitaria es un momento de especial relevancia en el inicio del consumo de drogas ilegales y suprevención, pudiendo este consumo estar especialmente relacionado con el apoyo familiar

Use of ecstasy and other psychoactive substances among school-attending adolescents in Taiwan: national surveys 2004–2006

<p>Abstract</p> <p>Background</p> <p>With the backdrop of a global ecstasy epidemic, this study sought to examine the trend, correlates, and onset sequence of ecstasy use among adolescents in Taiwan, where a well-established gateway drug such as marijuana is much less popular.</p> <p>Methods</p> <p>A multistage probability survey of school-attending adolescents in grades 7, 9, 10, and 12, aged 11–19 years, was conducted in 2004, 2005, and 2006. A self-administered anonymous questionnaire elicited response rates ranging from 94.3% to 96.6%. The sample sizes were 18232 respondents in 2004, 17986 in 2005, and 17864 in 2006.</p> <p>Results</p> <p>In terms of lifetime prevalence and incidence, ecstasy and ketamine by and large appeared as the first and second commonly used illegal drugs, respectively, among middle (grades 7 and 9) and high school students (grades 10 and 12) during the 3-year survey period; however, this order was reversed in the middle school-aged students starting in 2006. Having sexual experience, tobacco use, and betel nut use were factors consistently associated with the onset of ecstasy use across years. The majority of ecstasy users had been involved in polydrug use, such as the use of ketamine (41.4%–53.5%), marijuana (12.7%–18.7%), and methamphetamine (4.2%–9.5%).</p> <p>Conclusion</p> <p>From 2004 to 2006, a decline was noted in the prevalence and incidence rate of ecstasy, a leading illegal drug used by school-attending adolescents in Taiwan since the early 2000s. The emerging ketamine use trend may warrant more attention in the future.</p

Onchocerciasis (river blindness) – more than a century of research and control

This review summarises more than a century of research on onchocerciasis, also known as river blindness, and its control. River blindness is an infection caused by the tissue filaria Onchocerca volvulus affecting the skin, subcutaneous tissue and eyes and leading to blindness in a minority of infected persons. The parasite is transmitted by its intermediate hosts Simulium spp. which breed in rivers. Featured are history and milestones in onchocerciasis research and control, state-of-the-art data on the parasite, its endobacteria Wolbachia, on the vectors, previous and current prevalence of the infection, its diagnostics, the interaction between the parasite and its host, immune responses and the pathology of onchocerciasis. Detailed information is documented on the time course of control programmes in the afflicted countries in Africa and the Americas, a long road from previous programmes to current successes in control of the transmission of this infectious disease. By development, adjustment and optimization of the control measures, transmission by the vector has been interrupted in foci of countries in the Americas, in Uganda, in Sudan and elsewhere, followed by onchocerciasis eliminations. The current state and future perspectives for control, elimination and eradication within the next 20–30 years are described and discussed. This review contributes to a deeper comprehension of this disease by a tissue-dwelling filaria and it will be helpful in efforts to control and eliminate other filarial infections

Emigration and the Foundation of West Germany, 1933-1963

This dissertation traces the development of German national life from the disintegration of the Weimar Republic in 1933 to the end of the foundational period of the Federal Republic of Germany in 1963. Charting the alliances between previously hostile groups formed in emigration in response to National Socialism, I offer a way of understanding the ideological strength of reconstruction and nation-building after Hitler. The study covers four principal areas of activity: law and politics, humanistic culture, higher education, and religion. It takes as representative case studies the careers of young Weimar-era leaders who fled the Nazi regime in the 1930s and returned to help build the infrastructure of the Federal Republic after 1945. Extensive use is made of their personal papers and other archival material from the institutions with which they were affiliated. Examining the legal, cultural, intellectual, and theological response to the failure of Germany's first democracy, I challenge arguments that have privileged economic success as the driving cause of postwar democratization in West Germany. Instead, the dissertation points to the indispensability of social and ideological reconciliation as preconditions for development
