Factors influencing alcohol and illicit drug use amongst medical students

Alcohol consumption and alcohol-related problems among Vietnamese medical students

INTRODUCTION AND AIMS

This study examined prevalence and predictors of alcohol consumption and alcohol problems in a sample of medical students in Vietnam.

DESIGN AND METHODS

A cross-sectional survey using a multi-stage cluster sampling approach was conducted in 2007 in two universities in Vietnam. The students (n = 619, 100% response rate) completed questionnaires based on the Alcohol Use Disorder Identification Test. A score of >or=8 defined presence of alcohol problems. Data analyses adjusted for the cluster sampling approach.

RESULTS

Overall 65.5% of students had drunk alcohol during the previous year while alcohol problems were detected in 12.5%. Male students, students who reported that their family members drank and students who reported that their flat mates were drinking were more likely to be current drinkers. Male students were 14.3 times more likely to have an Alcohol Use Disorder Identification Test score of >or=8 compared with female students (P = 0.005).

DISCUSSION AND CONCLUSIONS

Intervention programs focusing on male students and their social environment are warranted. As Vietnamese society rapidly modernises prevention programs for female students may also be needed.

Psychoactive substance use and dependence among Spanish university students: prevalence, correlates, polyconsumption, and comorbidity with depression

In this study, the prevalence of psychoactive substance use and dependence was estimated among students at a Spanish university, together with associated factors, polyconsumption, and comorbidity with depression, using a 554-member sample stratified by sex, degree year, and discipline. 86.5% had consumed some potentially addictive psychoactive substance in the past month, and 10.5% satisfied DSM-IV criteria for dependence on nicotine, alcohol, caffeine, or cannabis. Polyconsumers (90.4%) consumed an average 3.2 different substances. Current depression implied increased likelihood of having consumed tobacco or psychoactive pharmaceutical drugs in the past month, and DSM-IV symptoms of major depressive episode were shown by 8.6% of 58 substance-dependent participants, 8.7% of 540 past-month legal substance consumers, and 12.1% of 140 past-month illegal substance consumers.

Drug consumption among medical students in São Paulo, Brazil: influences of gender and academic year

OBJECTIVE

To analyze alcohol, tobacco and other drug use among medical students.

METHOD

Over a five-year period (1996-2001), we evaluated 457 students at the Universidade de São Paulo School of Medicine, located in São Paulo, Brazil. The students participated by filling out an anonymous questionnaire on drug use (lifetime, previous 12 months and previous 30 days). The influence that gender and academic year have on drug use was also analyzed.

RESULTS

During the study period, there was an increase in the use of illicit drugs, especially inhalants and amphetamines, among the medical students evaluated. Drug use (except that of marijuana and inhalants) was comparable between the genders, and academic year was an important influencing factor.

DISCUSSION

Increased inhalant use was observed among the medical students, especially among males and students in the early undergraduate years. This is suggestive of a specific behavioral pattern among medical students. Our findings corroborate those of previous studies.

CONCLUSION

Inhalant use is on the rise among medical students at the Universidade de São Paulo School of Medicine. Because of the negative health effects of illicit drug use, further studies are needed in order to deepen the understanding of this phenomenon and to facilitate the development of preventive measures.

Social support and non-safe use of licit substances by Greek medical students

This study aims to investigate the relationship between social support and non-safe use of nicotine and alcohol among medical students, in relation to other contributing factors. Data were collected during 2002-2003. Participants (N = 135), medical students at the Democritus University of Thrace, Alexandroupolis, Greece, were allocated into groups per sex according to their smoking and alcohol drinking patterns. Comparisons were made with respect to rating scores on measures assessing perceived social support, psychopathological problems, stressful life events, physical health, and satisfaction with life. Data were analyzed using chi-square, Mann-Whitney U test, and factor analysis. Female students' non-safe use of licit substances is positively related to higher scores on perceived social support and lower scores on psychopathological dimensions. Despite some limitations of this study, findings bring about implications on antismoking and antialcoholic campaigns.

Enhancing the health of medical students: outcomes of an integrated mindfulness and lifestyle program

Medical students experience various stresses and many poor health behaviours. Previous studies consistently show that student wellbeing is at its lowest pre-exam. Little core-curriculum is traditionally dedicated to providing self-care skills for medical students. This paper describes the development, implementation and outcomes of the Health Enhancement Program (HEP) at Monash University. It comprises mindfulness and ESSENCE lifestyle programs, is experientially-based, and integrates with biomedical sciences, clinical skills and assessment. This study measured the program's impact on medical student psychological distress and quality of life. A cohort study performed on the 2006 first-year intake measured effects of the HEP on various markers of wellbeing. Instruments used were the depression, anxiety and hostility subscales of the Symptom Checklist-90-R incorporating the Global Severity Index (GSI) and the WHO Quality of Life (WHOQOL) questionnaire. Pre-course data (T1) was gathered mid-semester and post-course data (T2) corresponded with pre-exam week. To examine differences between T1 and T2 repeated measures ANOVA was used for the GSI and two separate repeated measures MANOVAs were used to examine changes in the subscales of the SCL-90-R and the WHOQOL-BREF. Follow-up t-tests were conducted to examine differences between individual subscales. A total of 148 of an eligible 270 students returned data at T1 and T2 giving a response rate of 55%. 90.5% of students reported personally applying the mindfulness practices. Improved student wellbeing was noted on all measures and reached statistical significance for the depression (mean T1 = 0.91, T2 = 0.78; p = 0.01) and hostility (0.62, 0.49; 0.03) subscales and the GSI (0.73, 0.64; 0.02) of the SCL-90, but not the anxiety subscale (0.62, 0.54; 0.11). Statistically significant results were also found for the psychological domain (62.42, 65.62; p < 0.001) but not the physical domain (69.11, 70.90; p = 0.07) of the WHOQOL. This study is the first to demonstrate an overall improvement in medical student wellbeing during the pre-exam period suggesting that the common decline in wellbeing is avoidable. Although the findings of this study indicate the potential for improving student wellbeing at the same time as meeting important learning objectives, the limitations in study design due to the current duration of follow-up and lack of a control group means that the data should be interpreted with caution. Future research should be directed at determining the contribution of individual program components, long-term outcomes, and impacts on future attitudes and clinical practice.

The use of psychoactive substances among medical students in southern Brazil

The objective of our study was to investigate the patterns of use of psychoactive substances among students of a medical school in Southern Brazil and to explore a putative role of discrete behavioral and social variables in their drug use. This is a descriptive and transversal cut study. All regularly enrolled medical students at the University of Caxias do Sul were invited to participate in the study. A self-administered questionnaire, which analyses lifetime drug use as well as drug use in the previous 30 days and 12 months was utilized to collect data. From a total of 318 regularly enrolled students, 183 (57.5%) completed and returned the questionnaires. The highest prevalence rates of lifetime drug use, drug use in the last 12 months and drug use in the last 30 days were observed, according to drug type, as follow in descending order: alcohol, tobacco, marijuana, inhalants, tranquilizers, amphetamine and cocaine. A multivariate analysis indicated that research respondents who live with their parents as well as those whose parents live together harmoniously, those who deny close ties to drug users, those who disapprove drug use, those who are not tobacco smokers and those who manifest religious beliefs and practice presented the most reduced levels of illicit drug use. The use of psychoactive substances among medical students in the University of Caxias do Sul is a significant problem. Appropriate and timely initiatives are needed to prevent and curb drug use among medical students.

Prescription opioid abuse and dependence among physicians: hypotheses and treatment

Physician impairment is a serious public health issue affecting physicians as well as their families, colleagues, and patients. Though physicians generally display healthier habits than members of the general population, overall rates of impairment are similar among both groups, and prescription drug abuse (including prescription opioids) is particularly problematic among physicians. The current review focuses mainly on prescription opioid abuse and dependence among physicians. It includes a brief history of early physician experiences with anesthetic and analgesic agents, and explores several hypotheses regarding the etiology of prescription opioid abuse and dependence among physicians. Barriers to identification and to treatment entry among physicians are discussed. In addition, methods of assessment and successful treatment in specialized impaired physician programs are described. Medical and psychosocial interventions, 12-step involvement, and extensive use of evaluations are highlighted. Attention is paid to typical follow-up contracting and monitoring strategies, as well as strategies for prevention. Given the extremely positive outcomes demonstrated by specialized programs for treating impaired professionals, it is recommended that their methods be disseminated and utilized in treatment centers for the general public.

Does gender predict medical students' stress in mansoura, egypt?

BACKGROUND

Medical education is perceived as being stressful with negative effects on students' mental health. However, few studies have addressed the influence of gender on stress in medical students.

AIM

To compare male and female medical students in Egypt on sources of stress, perception of stress, anxiety, depression, physical symptomatology, and personality profile.

METHODS

Data were collected through an anonymous self-administered questionnaire covering socio-demographic data, stressors, perceived stress scale, physical wellbeing factors, the Hospital Anxiety and Depression scale as well as neuroticism and extraversion subscales of the Eysenck Personality Questionnaire.

RESULTS

Stressors were reported by 94.5% of the total sample with equal gender proportions. Univariate analysis indicated that female students scored higher than males on depression and neuroticism scales while male and female medical students were similar on level of perceived stress, number of stressors, clinical anxiety, physical well-being factors and the extraversion scale. Multivariate logistic regression revealed that the independent predictors of a high stress level were the presence of more than five stressors, clinical anxiety and depression, and increased scores on the global sickness index and on the extraversion and neuroticism sub-scales.

CONCLUSION

Despite there being no significant difference in perceived stress according to gender, females were less likely to cite relationship problems with teachers and substance abuse as sources of stress. Moreover, females scored significantly higher than males on depression and neuroticism scales.

Evolutional pattern of drug use by medical students

Recent use of psychoactive substances among 456 medical students throughout the six grades was surveyed by way of a self-report questionnaire using World Health Organisation criteria. Among male medical students, the most frequently used substances were alcohol (80.5%), cannabis (25.3%), solvents (25.2%), and tobacco (25.2%), whereas among female students the most frequently used drugs were alcohol (72.6%), tobacco (14.6%), solvents (10.5%), and tranquillizers (7.5%). Switch from illegal to legal drugs were observed only among female medical students. Male students tend to alternate cannabis and solvents throughout college years. Interventions aiming to influence patterns of drug consumption among medical students must consider both gender differences and evolutional patterns of substance use throughout medical course.

Factors associated with the use of solvents and cannabis by medical students

INTRODUCTION

The use of alcohol and other drugs among medical students has been a theme of growing interest and concern on the part of researchers, teaching institutions and medical associations since the decade of the 1960's.

OBJECTIVE

Recent use of alcohol, tobacco, tranquillisers, amphetamines, cannabis, organic solvents, and cocaine among 456 medical students was surveyed.

METHOD

Assessment was done by means of a self-report questionnaire according to World Health Organisation guidelines.

RESULTS

Among medical students, after alcohol and tobacco, cannabis and solvents are the most frequently used psychoactive substances. As such, they were the most deeply analysed drugs in this study. Factors associated with the recent use of cannabis and solvents were established by logistic regression. Living with parents or a companion appeared as a protective factor for the use of cannabis. However, being male and regularly participating in the activities at the campus Sports Association showed as risk factors for the use of both cannabis and solvents.

DISCUSSION

Concepts and misconceptions concerning protective and risk factors must be discussed in the light of cultural and circumstantial interferences. Harm reduction strategies should be seriously considered.

Alcohol use in Czech pharmacy students

In academic years 2002/3-2004/5, the use of alcohol was investigated by anonymous questionnaire in 1,032 first and third year pharmacy students in the Czech Republic. Frequencies of beer, wine and spirits use, the age of the first contact with alcoholic beverages, the age of the first drunkenness and the frequency of drunkenness in the last month were ascertained. Average age of the first contact with alcoholic beverages was 12.9 years. 40.5% and 10.9% of students reported regular and hazardous drinking, respectively, with significantly higher proportion of men than women. Hazardous alcohol drinking significantly increased between academic years 2002/3 and 2004/5, no significant differences were found in the proportion of non-drinkers and regular alcohol drinkers over the 3-year-period of the survey. Both regular and hazardous drinking patterns were significantly related to the financial situation of the students. Significant associations were also found between alcohol consumption and using of both licit and illicit drugs of abuse.

Prevalence of psychoactive drug use among medical students in Rio de Janeiro

BACKGROUND

Drug use and abuse may hamper learning capabilities and the development of technical skills in medical students and, therefore, the quality of care offered to patients. The aim of this investigation was to estimate the prevalence of psychoactive drug use among medical students of public universities in Rio de Janeiro, Brazil, and to identify characteristics associated with substance use.

METHOD

This was a cross-sectional investigation designed to include all medical students of four universities. The final sample included 1,054 students. Patterns of licit and illicit drug use (at least once in lifetime drug use, drug use in the last 30 days (LTD) and CAGE) before and during medical school were assessed by a multiple-choice, self-administered anonymous questionnaire.

RESULTS

Alcohol abuse was more prevalent among male students from higher income families. Alcohol LTD use was more prevalent among male students with college-educated parents. Tobacco, cannabis and inhalant lifetime use was more prevalent among males and tranquillizer use among females. Tobacco, cannabis and tranquillizer lifetime use was more prevalent among students with divorced or dead parents. Inhalant lifetime use was more prevalent among students from higher income families. Students who had college-educated, divorced or dead parents or evidenced tobacco, cocaine or inhalant lifetime use were more prevalent among cannabis users. Male students from higher income families had higher prevalence of cocaine lifetime use.

CONCLUSION

Substance use in this group of medical students is not widespread compared to rates reported for developed countries. Preventive efforts should focus on alcohol and cannabis use by medical students.

A comparison of alcohol and drug use among dental undergraduates and a group of non-medical, professional undergraduates

OBJECTIVE

To compare the alcohol and drug use of dental and law undergraduates.

DESIGN

Anonymous self-report questionnaire.

SUBJECTS AND METHODS

All dental undergraduates (n = 263) and a randomly selected group of law undergraduates (n = 180) from the same university were questioned on their use of alcohol, tobacco and illicit drugs.

RESULTS

Current tobacco use was reported by 7% of dental students and 19% of law students. Alcohol use was reported by 86% of dental students and 88% of law students, with 44% of dental students and 52% of law students estimating they drank above recommended safe limits (14 units for females, 21 units for men). Binge drinking was reported by 71% of dental students and 75% of law students, with weekly binge drinking reported by 27% and 34% of dental and law students respectively. Cannabis experience was reported by 44% of dental students and 52% of law students, with current use reported by 12% and 25% of dental and law students respectively. A small proportion of dental and law students reported using other class A and B drugs including ecstasy, amphetamines and cocaine.

CONCLUSIONS

Dental students appear to be indulging in similar levels of alcohol and illicit drug use when compared to students of a different, non-medical faculty. Binge drinking may be more prevalent than previously thought, with potential risks to health, patient safety and professional status.

Trends in medical student use of tobacco, alcohol and drugs in an Irish university, 1973-2002

Questionnaire surveys of medical students in an Irish university were carried out in 1973 (n=765), 1990 (n=522) and 2002 (n=537), with differentiation of western students (e.g., from the Republic of Ireland, the UK, or Australia) and non-western students (e.g., Malaysia). We report on changes in tobacco smoking, drinking and drug-taking over three decades, and we note that, among western students, estimated prevalence of being a current smoker has declined overall from 28.8% in 1973 to 15.3% in 1990 to 9.2% in 2002 (p<0.001), falling in both males (p<0.001) and females (p<0.01). Ex-smokers rose from 5.9% to 15.1% between 1990 and 2002, corresponding with the decline in current smokers. The prevalence of current drinkers has risen over the period, to 82.5% among western students in 2002 (p<0.05); female drinking has increased steadily since 1973 (p<0.001), and the overall proportion of CAGE-positive drinkers has risen since 1990 (p<0.001). The mean weekly alcohol consumption has risen in both sexes since 1990 (males 14.3 units to 19.4, p<0.01; females 6.0 to 9.5, p<0.001). There was an increase in the proportion of students ever offered drugs between 1973 and 2002 (p<0.001). Although smoking rates have fallen, our findings show a marked increase in alcohol and drug consumption between 1973 and 2002. Personal misuse of addictive substances by doctors may mean that doctors will fail to take misuse by patients seriously. A need for preventative and ameliorative action during the medical school years is clear.

Medical school selection: Screening for dysfunctional tendencies

AIM

One of the aims of medical selection is to deselect students who have personal characteristics that would impact negatively on their ability to interact with patients, supervisors and peers and impede their ability to cope with the stress of medical training. The arduous requirements of the formal curriculum, the customs and rituals of the socialisation process and the mistreatment and abuse reportedly experienced by students all contribute to stress, mental illness, suicide, lowered self-confidence in clinical ability, decreased ability to learn and alcohol and substance abuse. There has been little research on the effectiveness of the selection interview in deselecting students with negative personal characteristics. Our research profiles the dysfunctional interpersonal tendencies of students already selected into a medical programme through the process of academic merit, application and interview.

METHODS

During 2001 and 2002, 159 students enrolled in an Australian undergraduate medical programme completed the Hogan Development Survey (HDS), which is a self-report measure of dysfunctional personality characteristics that inhibit the development of working relationships with others.

RESULTS

The HDS identified negative personality characteristics in medical students that were not detected in the selection interview.

CONCLUSIONS

The presence of patterns of dysfunctional behaviour in medical training has implications for the selection, teaching and pastoral care of medical students. The HDS has the potential to identify negative personal characteristics that are hard to detect during a selection interview, and may be a valuable adjunct to the interview.

Medical student attitudes to risk taking and self-perceived influence on medical practice

CONTEXT

Little has been published on medical student risk-taking attitudes and behaviours and whether students think these attributes will affect how they treat patients.

OBJECTIVES

Our aims were to assess for an association between risk-taking attitudes and behaviours, such as problematic substance use, self-reported risky behaviours, and self-reported accidents, and to test for an association between risk-taking attitudes and student perceptions of the influence of these attitudes on future clinical practice.

METHODS

Three consecutive classes of Year 2 medical students (n=315) completed a self-administered, 29-item questionnaire. Risk-taking attitudes were evaluated using a 6-question, risk-taking scale adapted from the Jackson Personality Inventory (JPI).

RESULTS

A significant positive correlation was demonstrated between risk-taking attitudes (JPI) and problematic substance use (r=0.34; P<0.01), self-reported risky behaviours (r=0.47; P<0.01), and self-reported accidents (r=0.33; P<0.01). Students who did not think their attitudes toward risk would affect their clinical decision making scored significantly higher on our measure of risk-taking attitudes (t306=-4.60; P<0.01). Students who did not think that their drinking, drug taking or sexual behaviour would affect how they counselled patients on these matters scored significantly higher on our measure of problematic substance use (t307=-2.51; P=0.01).

CONCLUSIONS

Although risk-taking attitudes have been associated with significant differences in clinical decision making among doctors, in our sample students with high risk-taking attitudes and behaviours were significantly less likely than their colleagues to think their attitudes would affect their clinical practice. Implications for medical education are discussed.

Excessive drinking and other problem behaviours among 14-16 year old schoolchildren

The study investigates excessive drinking and associations with other problem behaviours in 2078 school students aged 14-16 years in seven London secondary schools. Using a cross-sectional design, a self-completion questionnaire assessed lifetime and recent (past month) alcohol and drug consumption, attitudes to alcohol use education, alcohol-related problems, psychological problems, educational aspirations, truancy, and delinquent behaviour. Excessive drinking was operationally defined as 10 or more units of alcohol per drinking occasion. At least one episode of excessive drinking was reported by 32% of the sample, with 10% reporting five or more episodes. Excessive drinking was positively associated with frequency of cigarette smoking, use of cannabis, positive attitudes towards illicit drugs, low educational aspirations, higher depression scores, frequent truancy, and involvement in delinquent behaviours. Excessive drinking is a problematic behaviour in its own right but it is also a marker for other problem behaviours, including illicit drug misuse and delinquency. Understanding and responding to alcohol misuse among adolescents requires attention to psychological, social and developmental factors other than alcohol consumption alone.

Factors associated with recreational drug use

This study aimed to examine demographic, lifestyle, mental health and personality factors associated with illicit recreational drug use, heavy alcohol consumption and smoking in a community-based population sample. A postal questionnaire survey was conducted of people who were selected at random from the Electoral registers of Cardiff and Merthyr Tydfil. Illicit drug use was associated with risk taking, neuroticism, being male, having a higher education qualification, not being married, being unemployed, being aged under 25 years, smoking, heavy alcohol consumption and living in Cardiff. Smoking was associated with anxiety, depression, being female, lower income and educational qualifications, looking after the family or home, being aged over 25 years, illicit drug use and heavy alcohol use. Heavy alcohol consumption was associated with not being depressed, experiencing sleeping problems, risk taking, being male, higher income, no higher educational qualification, not being married, being a student, being aged under 25 years, smoking and illicit drug use. Illicit drug use, smoking and heavy alcohol use were strongly associated with each other. Illicit drug use was associated with alcohol use and, to an even greater extent, with smoking. Illicit drug and alcohol use were associated with similar characteristics, but smoking was associated with a rather different demographic combination.

The role of occupational stress in the maladaptive use of alcohol by dentists: a study of South Australian general dental practitioners

BACKGROUND

It is well recognized that dentistry is a stressful profession. However, there are conflicting views about the extent to which such stress contributes to hazardous drinking among dentists. In addition, the relative contributions of stress and pre-existing vulnerability in predicting alcohol problems among dentists generally (and Australian dentists in particular) have yet to be determined.

METHODS

The levels of stress and alcohol consumption of 312 South Australian dentists were measured. Factors known to mediate vulnerability to alcohol disorders were also assessed with appropriate psychometric instruments.

RESULTS

High levels of stress/burnout, consistent with other studies of dentists' stress, were recorded. Hazardous levels of alcohol consumption, which were between two and four times higher than the normative South Australian population, were also reported, particularly among males and rural dentists.

CONCLUSIONS

To a significant extent, stress and hazardous alcohol consumption are both present among South Australian dentists. However, compared with work stress/burnout, existing personal vulnerability factors are much stronger predictors of such hazardous alcohol consumption. We suggest that professional dental bodies, and state Dental Boards, may play a role in ensuring stress inoculation and guidance on safe limits of alcohol consumption for dentists-in-training; and in creating appropriate mechanisms for assisting dentists who experience alcohol related difficulties.

Fostering students' personal and professional development in medicine: a new framework for PPD

CONTEXT

Altruism, accountability, duty, integrity, respect for others and lifelong learning are qualities that have been identified as central to medical professionalism. However, we do not have a systematically developed understanding of what is needed to optimise medical students' personal and professional development (PPD). We need some level of agreement on how to teach and assess PPD, but traditional educational methods may not be strong determinants of students' or graduates' actual behaviour in clinical settings.

AIMS

This paper considers the factors that demonstrably influence doctors' behaviour as a contribution to the development of a model for considering PPD within the broader context of medical practice. The model presented acknowledges that behaviour change comes about through a number of influences including education, feedback, rewards, penalties and participation. These elements can be plotted against the cognitive, affective and metacognitive processes that are intrinsic to learning.

IMPLICATIONS

A framework that promotes the consideration of all of these factors in PPD can provide guidance for schools undergoing curriculum reform and inform further research into one of the most important and challenging aspects of medical education.

Padrão do ciclo sono-vigília e sua relação com a ansiedade em estudantes universitários

Neste trabalho, foram investigadas as relações entre o ciclo sono-vigília e a ansiedade. O ciclo sono-vigília e traço e estado de ansiedade foram avaliados em 37 estudantes do segundo ano do curso médico. Os estudantes responderam ao Índice de Qualidade de Sono de Pittsburgh - IQSP, ao Inventário de Estado e Traço de Ansiedade - IDATE e a um questionário de matutinidade - vespertinidade (cronotipo). Todos registraram seu sono em um diário durante duas semanas. Os resultados mostraram que os estudantes de medicina tinham altos escores de traço e estado de ansiedade. Aqueles que tinham maiores escores de traço de ansiedade acordavam mais cedo nos dias de semana e finais de semana enquanto os que apresentavam irregularidade do seu ciclo sono-vigília apresentaram maior estado de ansiedade. Sugere-se que há uma relação entre o ciclo sono-vigília e a ansiedade.

The changing patterns of drinking, illicit drug use, stress, anxiety and depression in dental students in a UK dental school: a longitudinal study

OBJECTIVE

To investigate alcohol and illicit drug use in a cohort of dental undergraduates through to VT year.

SETTING

A UK dental school (with a medical school comparison group).

SUBJECTS AND METHODS

A cohort of dental students anonymously completed a lifestyle questionnaire about drinking and smoking, illicit drug use, stress, anxiety and depression in the spring of 1995 and 1998 as second and final year undergraduate students respectively, and in the summer of 1999 after one year working as qualified dentists. A parallel cohort of medical students also anonymously completed the questionnaire at the same time points in their undergraduate course as for the dental students, and at the end of a year working as Pre-Registration House Officers (PRHOs).

RESULTS

The proportion of dental students in Newcastle drinking above the recommended low risk limits of alcohol declined from 47% as second year students to 25% as final year students and then it increased to 41% as qualified dentists, whilst in medical students it steadily increased over the three time points of the survey (33% to 43% to 54%). A greater proportion of dental students were drinking at hazardous levels at all three time-points, compared with medical students. Experimentation with illicit drugs ranged from 47% as second year students to 54% as final year students and to 51% as dentists. The prevalence of illicit drug use in medical students was similar to that in dental students. Forty seven per cent of the dental student cohort as second year students, 67% as final year students and 16% as dentists suffered from possible pathological anxiety, compared with 47%, 26% and 30% in the medical student cohort. The proportion of dentists suffering from stress decreased from 72% as final year students to 19% as dentists. In the medical student group, the proportion increased from 32% as final year students to 39% as PRHOs.

CONCLUSION

This longitudinal study revealed that a high proportion of dental students from Newcastle continue to drink excessively and experiment with illicit drugs both as undergraduates and as practising dentists. A significant proportion also suffer from anxiety and stress. Further measures are needed in order to reduce alcohol and substance misuse and stress and anxiety among dental students and dentists.

Substance use among adolescents in Taiwan: associated personality traits, incompetence, and behavioral/emotional problems

BACKGROUND

Despite that adolescent substance use is increasingly prevalent throughout the world and leads to increased risk of progression to illicit drug use, few studies have examined in detail individual features that are associated with such use. We aimed to examine personality traits, incompetence, and behavioral/emotional problems in relation to adolescent substance use and possible interactions between these factors.

METHODS

Junior high school adolescents (N = 905) randomly selected from Taipei in 1996 completed a questionnaire consisting of substance use experience, the Junior Eysenck Personality Questionnaire (JEPQ), and the Tridimensional Personality Questionnaire (TPQ). Students' parents (N = 854) were asked to complete the Child Behavior Checklist. Logistic regression was used to assess the relationship between substance use and personality traits or behavioral problems.

RESULTS

The most commonly used substance was liquid substance (alcohol and refreshing beverage), followed by tobacco and betel nut with an age-related trend in boys. Associated factors of substance use included higher Extroversion and lower Lie Scale (as measured in the JEPQ), higher Novelty Seeking (as measured in the TPQ), poorer School Competence, and more Delinquent Behavior, Aggressive Behavior, and Somatic Complaints. The associations remained unchanged with potential confounders controlled for.

CONCLUSIONS

Adolescents who use substance have specific individual features that are readily assessable by existing instruments. This bears important implications for the early intervention of substance abuse in adolescents.

Drink and drugs: from medical students to doctors

Drinking and illicit drug use were assessed longitudinally in a cohort of medical students who were surveyed in the second and fifth year of their undergraduate studies and after 1 year as PRHOs. Mean alcohol consumption had increased significantly (P<0.015) over the three time points; 15.2-16.0-18.8 units/week. Experimentation with illicit drugs had increased from 50 to 63 to 65%. Although education on alcohol and illicit drugs should be part of core curriculum in medical schools, support and intervention in the workplace is also needed for individuals with alcohol and/or drug problems.
