The Prevalence of the Burnout Syndrome and Factors Associated in the Students of Dentistry in Integral Clinic: A Cross-Sectional Study

Background

Burnout syndrome (BS) is composed of three interrelated dimensions (emotional exhaustion, depersonalization, and personal fulfillment), and it has been documented that it affects health professionals from an early age.

Aims

Determine the prevalence of BS and associated factors in the integral clinic of the Dentistry Pilot School. Material and Methods. Two instruments were applied: (1) Maslach Burnout Inventory, which measures the degree of professional burnout through 22 items that describe the professional's attitudes and feelings toward work, as well as symptoms associated with this phenomenon; (2) the second questionnaire determines the possible symptoms of BS and consists of 14 questions that describe tiredness, sleep problems, digestive problems, respiratory problems and headaches, temporomandibular joint (TMJ), neck pain, back pain, and upper and lower extremity pain. The instruments were answered anonymously by a total of 300 students who participated in the study.

Results

The emotional exhaustion of the participants was 48.3% at a higher level, the depersonalization was 46.7% at a higher level, and the low perception of personal fulfillment was 73%. In addition, it was shown that BS is significantly related to marital status (p < 0.001∗), with single people reporting being more exhausted, with the 6-month level (p = 0.011) and with the following symptoms: non-neck pain, head, TMJ, back, waist, upper and lower body pain.

Conclusion

It was found that the BS had a prevalence of high levels of exhaustion and depersonalization correlated with the marital status and level of preparation (academic degree) of the person, finding a prevalence of symptoms such as pain in the neck, head, TMJ, and back.

Illicit drug use in university students in the UK and Ireland: a PRISMA-guided scoping review

BACKGROUND

Interest in the health and well-being of university students has increased in the UK and Ireland in the past two decades as their numbers have grown. Recent high-profile deaths of students after using illicit drugs have highlighted the importance of the topic for policy makers. This scoping review maps the state of the existing literature evaluating use of illicit drugs in university students in the UK and Ireland. It aims to highlight research gaps and inform policy.

METHOD

We conducted a systematic search of papers related to psychoactive drug use in university students in the UK and Ireland published before August 2021. The 18 extracted study characteristics included author(s); year of publication; journal; location of data collection; study design; delivery method (e.g., online survey, in-person, postal survey); number of participants; response rate; participant course of study, year of study, degree level (i.e., undergraduate, postgraduate), gender and age; time-period assessed (e.g., lifetime, current use, past 12 months); primary aim; primary outcome; ethical approval; and funding source.

RESULTS

The PRISMA-guided search strategy identified 1583 papers for abstract review; of 110 papers retained for full-text review, 54 studies met criteria for inclusion for this paper. Primary outcomes were coded into five groups: prevalence and patterns of drug use; factors associated with drug use; attitudes and knowledge about, and motivation for, drug use; supply of drugs; consequences of drug use. The results show that there is no coherent body of research in this area. The prevalence of reported drug use has crept up and the range of substances reported has broadened over time, and attitudes to drugs on average have normalised. However, there are significant methodological limitations that limit the utility of these findings. There was little evidence of published work on prevention of, or intervention to reduce, drug-related harms.

CONCLUSION

The domains identified offer a framework for university administrators, researchers and policy makers to understand the potential response to drug use in university students in the UK and Ireland. Recommendations are made to fill the gaps in the research evidence base.

Prevalence and Psychiatric Correlates of Illicit Substance Use in UK Undergraduate Students

This study examined the prevalence of illegal drug use in UK students and motivators behind such behavior. Additionally, we explored possible relationships between substance use, psychosocial motivators, and psychiatric distress. A group (n = 543) of students completed online measures of substance use, anxiety, depression, perceived stress, and insomnia. A series of reasons behind their use were ranked based on importance. Reported cannabis, cocaine, nitrous oxide, ketamine, and MDMA use were most prevalent based on lifetime, past year, and month assessments. The experience of anxiety, depression, perceived stress, and insomnia were related to increased reports of substance use. Poor self-confidence and self-medication were key motivators of illicit drug use in those presenting greater psychiatric distress. These outcomes add to the sparse body of literature concerning illicit substance use in relation to psychiatric distress amongst UK students. Furthermore, we provided novel insight into the psychosocial motivators of such use.

Recreational Nitrous Oxide Use and Associated Factors among Health Profession Students in France

The first aim of this study was to investigate the recreational use of nitrous oxide (N₂O) among health profession students at Montpellier University (France). The second aim was to identify the factors associated with N₂O use. All students in medicine, dentistry, pharmacy and midwifery of the Montpellier University were contacted by email to participate in the survey. The students answered directly online by filling out anonymously a questionnaire including demographic information and questions about N₂O, illicit drugs and alcohol use. Ethical approval was granted by the ethics committee of the Montpellier University. The sample comprised 593 students (mean age = 22.3 ± 2.6 yr), with 68.6% of females. Lifetime N₂O use was reported by 76.6% and frequent alcohol use by 30.5% of the respondents. The lifetime use of cannabis, 'poppers', cocaine, ecstasy and LSD was 26.8%, 54.6%, 9.6%, 10.1% and 2.0% respectively. In multivariate analysis, the substances significantly associated with lifetime N₂O were alcohol drinking and 'poppers' use. With respect to this self-nominated sample, our results indicate that respondents who were alcohol drinkers, were poppers users, follow longer studies, divert medical products for recreational use or were members of a students' corporation had higher odds of lifetime N₂O use.

Self-Reported Illicit Drug Use Among Norwegian University and College Students. Associations With Age, Gender, and Geography

Background and Aims: Several studies have pointed to relatively high levels of illicit drug use among students in higher education compared to the general population. The aim of the present study was to provide an updated examination of self-reported illicit drug use among Norwegian University and college students. Methods: Data stem from the SHoT study (Students' Health and Well-being Study), a nationwide cross-sectional survey for higher education in Norway including Norwegian full-time students aged 18-35. Self-reported illicit drug use across a range of specified drugs comprised the outcome variables. Information on gender, age, and study location (geographical area) was also collected and used as stratification variables. The SHoT-survey from 2018 (N = 50,054) was used for the analyses of associations between demographical variables and illicit drug use, while trends in illicit drug use were estimated by comparing the 2018-results with data from the SHoT-surveys conducted in 2010 and 2014. Results: The proportion of students reporting having ever tried illicit drugs increased from 2014 to 2018, for both males (30.8 vs. 36.7%) and females (17.5 vs. 24.0%, both p < 0.001), while only minimal changes occurred between 2010 and 2014. The most commonly used illicit drugs during the past 12 months in 2018 were cannabis (15.2%), followed by MDMA (4.0%), cocaine (3.0%), and LSD/psilocybin (2.1%). Illicit drug use showed both linear increase with age, and inverted U-shaped relationships that peaked in the age span from 23 to 28 years of age. Males reported higher illicit drug use compared with females for all drugs. Proportions of illicit drug use varied across geographical areas within the country, with the highest use being reported in the Oslo area (the largest city and capital of Norway). Conclusions: The present study reports an increase from 2010 to 2018 among Norwegian University and college students in the proportion of those reporting to have tried illicit drugs. Despite varying proportions of use across type of drug, age, gender, and geographical location, the overall high levels of illicit drug use past 12 months confirm the need to address illicit drug use in this population.

The legal and moral perceptions of clinical and non-clinical undergraduates regarding substance use: a pilot project

Introduction Heavy alcohol and illicit drug use has been documented amongst medical and dental professionals and educational programs have been developed to attempt to reduce such behaviour in clinical undergraduates. This pilot study aims to investigate the legal and moral perceptions of substance use in clinical and non-clinical undergraduates.Method A cross-sectional self-report questionnaire was administered to 107 clinical and non-clinical undergraduates to investigate their moral and legal perceptions of alcohol and illicit substance use.Results More clinical (72.5%) than non-clinical students (66%) drink alcohol regularly. Both groups perceive ecstasy, cocaine and ketamine as 'high risk' drugs. A third of both clinical (34%) and non-clinical (36%) students support the legalisation of illicit drugs. Forty-seven percent of non-clinical students would consider changing their behaviour if illicit substances were legalised compared to 32% of clinical students. Clinical students believe the legal punishment for Class A drugs is appropriate, but disagree with that for Class C drug use. Personal values of clinical students differ regarding some immoral activities. Social perceptions of illicit substance users are similar for both clinical and non-clinical students with those who use heroin perceived most negatively by 86.5% of all undergraduates.Conclusion Individual substance use behaviours may be influenced by legal perceptions of illicit substance use. Personal values and social norms are also likely to be important. Further research is required to investigate how these perceptions affect a clinical student's decision to participate in excessive alcohol and illicit substance use behaviours.

Substance Use among a Sample of Healthcare Workers in Kenya: A Cross-Sectional Study

This study describes reported substance use among Kenyan healthcare workers (HCWs), as it has implications for HCWs' health, productivity, and their ability and likelihood to intervene on substance use. The Alcohol Smoking and Substance Involvement Screening Test (ASSIST) was administered to a convenience sample of HCWs (n = 206) in 15 health facilities. Reported lifetime use was 35.8% for alcohol, 23.5% for tobacco, 9.3% for cannabis, 9.3% for sedatives, 8.8% for cocaine, 6.4% for amphetamine-like stimulants, 5.4% for hallucinogens, 3.4% for inhalants, and 3.9% for opioids. Tobacco and alcohol were also the two most commonly used substances in the previous three months. Male gender and other substance use were key predictors of both lifetime and previous three months' use rates. HCWs' substance use rates appear generally higher than those seen in the general population in Kenya, though lower than those reported among many HCWs globally. This pattern of use has implications for both HCWs and their clients.

Coping strategies and the Salutogenic Model in future oral health professionals

BACKGROUND

Attention to the role of context in shaping individuals' coping strategies is necessary. This study used the Salutogenic Model (SM) as a framework to identify the coping strategies of oral health profession students from three countries.

METHODS

Students from Australia, New Zealand and Chile were invited to participate in this cross-sectional study, and were given a questionnaire including socio-demographics, the Perceived Stress Scale, The SOC-13 and the Brief COPE. Descriptive analysis, correlation analysis and profile analysis were computed using SPSS v 20.0.

RESULTS

Eight-hundred and ninety-seven valid questionnaires were returned, achieving a 44 % response rate. The coping dimension that the participants most commonly reported using was "Active Coping" with a mean value of 5.9 ± 1.5. Chilean respondents reported higher stress levels (19.8 vs. 17.7) and a lower Sense of Coherence (55.6 vs. 58.0) compared to Australian/New Zealand participants (p < 0.001). The SOC was positively correlated with active coping (p < 0.01) and positive reframing (p < 0.01). Profile analysis showed that when the differences in responses by sex were accounted for, there was no significant effect by country on the coping strategies used (p < 0.32).

CONCLUSION

This initial investigation provides insights into the students' coping strategies and the validity of the SM. Students reporting high SOC scores where those who demonstrated the use of active coping and positive reframing as strategies to deal with stressful situations, which indicates the accuracy of the theoretical framework of the SM in health education environments. The results also suggest that a distinctive coping strategy pattern may apply to all participants, regardless of their country and sex.

Tobacco, Alcohol and Drug Use among Dental Undergraduates at One UK University in 2015

The aim of this study was determine the prevalence of tobacco, alcohol and illicit substance use among dental undergraduates at one UK university in 2015. A cross-sectional survey of all 344 dental undergraduates using an anonymous self-report questionnaire was carried out. The response rate was 77%, of which 29% were male and 71% female. Tobacco smoking was reported by 23.6% of males and 12.2% of females, with only 1.6% of females reporting to smoke ≥10 cigarettes per day. Alcohol consumption was reported by 85.5% of males and 84% of females, and reported levels of alcohol consumption increased since becoming undergraduates. Binge drinking was reported by 35.3% of males and 41% of female students. Only 2.6% of males and 0.5% of females reported to be current regular users of cannabis. The vast majority of respondents claimed to have never used any illicit substance. The only other reported regularly used substances by males was Ecstasy (1.3%) and by females were LSD (0.5%), Ecstasy (1.5%), Cocaine (0.5%), Inhalants (0.5%) and Ketamine (0.5%). These results are encouraging. Fewer students reported smoking than in the general population, levels of binge drinking were considerably lower than previously reported figures, as were the numbers of regular users of cannabis and other illicit substances.

Social norms information for alcohol misuse in university and college students

BACKGROUND

Drinking is influenced by youth perceptions of how their peers drink. These perceptions are often incorrect, overestimating peer drinking norms. If inaccurate perceptions can be corrected, young people may drink less.

OBJECTIVES

To determine whether social norms interventions reduce alcohol-related negative consequences, alcohol misuse or alcohol consumption when compared with a control (ranging from assessment only/no intervention to other educational or psychosocial interventions) among university and college students.

SEARCH METHODS

The following electronic databases were searched up to July 2015: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, PsycINFO. The Cumulative Index to Nursing and Allied Health Literature (CINAHL) only to March 2008. Reference lists of included studies and review articles were manually searched. No restriction based on language or date was applied.

SELECTION CRITERIA

Randomised controlled trials or cluster-randomised controlled trials that compared a social normative intervention versus no intervention, alcohol education leaflet or other 'non-normative feedback' alcohol intervention and reported on alcohol consumption or alcohol-related problems in university or college students.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by Cochrane. Each outcome was analysed by mode of delivery: mailed normative feedback (MF); web/computer normative feedback (WF); individual face-to-face normative feedback (IFF); group face-to-face normative feedback (GFF); and normative marketing campaign (MC).

MAIN RESULTS

A total of 70 studies (44,958 participants) were included in the review, and 63 studies (42,784 participants) in the meta-analyses. Overall, the risk of bias assessment showed that these studies provided moderate or low quality evidence.Outcomes at four or more months post-intervention were of particular interest to assess when effects were sustained beyond the immediate short term. We have reported pooled effects across delivery modes only for those analyses for which heterogeneity across delivery modes is not substantial (I(2) < 50%).Alcohol-related problems at four or more months: IFF standardised mean difference (SMD) -0.14, 95% confidence interval (CI) -0.24 to -0.04 (participants = 2327; studies = 11; moderate quality evidence), equivalent to a decrease of 1.28 points in the 69-point alcohol problems scale score. No effects were found for WF or MF.Binge drinking at four or more months: results pooled across delivery modes: SMD -0.06, 95% CI -0.11 to -0.02 (participants = 11,292; studies = 16; moderate quality evidence), equivalent to 2.7% fewer binge drinkers if 30-day prevalence is 43.9%.Drinking quantity at four or more months: results pooled across delivery modes: SMD -0.08, 95% CI -0.12 to -0.04 (participants = 21,169; studies = 32; moderate quality evidence), equivalent to a reduction of 0.9 drinks consumed each week, from a baseline of 13.7 drinks per week.Drinking frequency at four or more months: WF SMD -0.11, 95% CI -0.17 to -0.04 (participants = 9929; studies = 10; moderate quality evidence), equivalent to a decrease of 0.17 drinking days/wk, from a baseline of 2.74 days/wk; IFF SMD -0.21, 95% CI -0.31 to -0.10 (participants = 1464; studies = 8; moderate quality evidence), equivalent to a decrease of 0.32 drinking days/wk, from a baseline of 2.74 days/wk. No effects were found for GFF or MC.Estimated blood alcohol concentration (BAC) at four or more months: peak BAC results pooled across delivery modes: SMD -0.08, 95% CI -0.17 to 0.00 (participants = 7198; studies = 11; low quality evidence), equivalent to a reduction in peak BAC from an average of 0.144% to 0.135%. No effects were found for typical BAC with IFF.

AUTHORS' CONCLUSIONS

The results of this review indicate that no substantive meaningful benefits are associated with social norms interventions for prevention of alcohol misuse among college/university students. Although some significant effects were found, we interpret the effect sizes as too small, given the measurement scales used in the studies included in this review, to be of relevance for policy or practice. Moreover, the significant effects are not consistent for all misuse measures, heterogeneity was a problem in some analyses and bias cannot be discounted as a potential cause of these findings.

Prevalence of and factors associated with regular khat chewing among university students in Ethiopia

Purpose

Khat (Catha edulis) is commonly chewed for its psychostimulant and euphorigenic effects in Africa and the Arabian Peninsula. Students use it to help them study for long hours especially during the period of examination. However, how regularly khat is chewed among university students and its associated factors are not well documented. In this article we report on the prevalence of and factors associated with regular khat chewing among university students in Ethiopia.

Methods

We did a cross-sectional study from May 20, 2014 to June 23, 2014 on a sample of 1,255 regular students recruited from all campuses of Hawassa University, southern Ethiopia. The data were collected using self-administered questionnaires. We analyzed the data to identify factors associated with current regular khat chewing using complex sample adjusted logistic regression analysis.

Results

The prevalence of current regular khat chewing was 10.5% (95% confidence interval [CI]: 6.1%–14.9%). After controlling for sex, religion, year of study, having a father who chews khat, cigarette smoking and alcohol drinking in the adjusted logistic regression model, living off-campus in rented houses as compared to living in the university dormitory (adjusted odds ratio [95% CI] =8.09 [1.56–42.01]), and having friends who chew khat (adjusted odds ratio [95% CI] =4.62 [1.98–10.74]) were found to significantly increase the odds of current regular khat use.

Conclusion

Students living outside the university campus in rented houses compared to those living in dormitory and those with khat chewing peers are more likely to use khat. A multipronged prevention approach involving students, the university officials, the surrounding community, and regulatory bodies is required.

Social norms information for alcohol misuse in university and college students

BACKGROUND

Drinking is influenced by youth (mis)perceptions of how their peers drink. If misperceptions can be corrected, young people may drink less.

OBJECTIVES

To determine whether social norms interventions reduce alcohol-related negative consequences, alcohol misuse or alcohol consumption when compared with a control (ranging from assessment only/no intervention to other educational or psychosocial interventions) among university and college students.

MAIN RESULTS

A total of 66 studies (43,125 participants) were included in the review, and 59 studies (40,951 participants) in the meta-analyses. Outcomes at 4+ months post intervention were of particular interest to assess when effects were sustained beyond the immediate short term. We have reported pooled effects across delivery modes only for those analyses for which heterogeneity across delivery modes is not substantial (I(2) < 50%). Alcohol-related problems at 4+ months: IFF standardised mean difference (SMD) -0.16, 95% confidence interval (CI) -0.31 to -0.01 (participants = 1065; studies = 7; moderate quality of evidence), equivalent to a decrease of 1.5 points in the 69-point alcohol problems scale score. No effects were found for WF or MF. Binge drinking at 4+ months: results pooled across delivery modes: SMD -0.06, 95% CI -0.11 to -0.02 (participants = 11,292; studies = 16; moderate quality of evidence), equivalent to 2.7% fewer binge drinkers if 30-day prevalence is 43.9%. Drinking quantity at 4+ months: results pooled across delivery modes: SMD -0.08, 95% CI -0.12 to -0.05 (participants = 20,696; studies = 33; moderate quality of evidence), equivalent to a reduction of 0.9 drinks consumed each week, from a baseline of 13.7 drinks per week. Drinking frequency at 4+ months: WF SMD -0.12, 95% CI -0.18 to -0.05 (participants = 9456; studies = 9; moderate quality of evidence), equivalent to a decrease of 0.19 drinking days/wk, from a baseline of 2.74 days/wk; IFF SMD -0.21, 95% CI -0.31 to -0.10 (participants = 1464; studies = 8; moderate quality of evidence), equivalent to a decrease of 0.32 drinking days/wk, from a baseline of 2.74 days/wk. No effects were found for GFF or MC. Estimated blood alcohol concentration (BAC) at 4+ months: peak BAC results pooled across delivery modes: SMD -0.08, 95% CI -0.17 to 0.00 (participants = 7198; studies = 13; low quality of evidence), equivalent to a reduction in peak PAC from an average of 0.144% to 0.135%. No effects were found for typical BAC with IFF.

AUTHORS' CONCLUSIONS

The results of this review indicate that no substantive meaningful benefits are associated with social norms interventions for prevention of alcohol misuse among college/university students. Although some significant effects were found, we interpret the effect sizes as too small, given the measurement scales used in the studies included in this review, to be of relevance for policy or practice. Moreover, the statistically significant effects are not consistent for all misuse measures, heterogeneity was a problem in some analyses and bias cannot be discounted as a potential cause of these findings.

Smoking among dental students at King Saud University: Consumption patterns and risk factors

OBJECTIVE

To assess smoking prevalence among dental students at King Saud University (KSU) and to determine possible risk factors of tobacco use.

METHODS

A self-addressed invitation letter was sent to all dental students (males and females) at KSU requesting participation in this study. Data on smoking habits, associated risk factors, and demographic factors, such as age, marital status, residency status, the student's year of study, and grade point average, were collected by an electronic self-administered questionnaire sent via email. Data were analyzed using SPSS. Significant differences between different groups were assessed with a Pearson Chi-Square test at α = 0.05. Logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence interval (95% CI) and to determine the effect of different risk factors on students' smoking habits.

RESULTS

Of the 600 registered dental students, 400 students responded (230 males, 170 females), representing a response rate of 67%. More male than female students were current smokers (27.6% vs. 2.4%, p < 0.001). Most smokers used shisha tobacco only (N = 35, 51.5%), followed by both shisha tobacco and cigarettes (N = 17, 25%), or cigarettes only (N = 16, 23.5%). Male students were about 4 times more likely to be smokers if all or most of their friends were smokers compared to students who had some friends who smoked (OR = 3.9, 95% CI = 1.9-7.7). A high proportion of current smokers (47.8%) reported stress as the main reason for smoking. Twenty-six percent of dental students (N = 87) who are currently nonsmokers reported that they have used tobacco at some point in their lives. Over two thirds of sampled students (63%) believed that public tobacco usage is not well addressed in the current college curriculum.

CONCLUSION

Approximately one in every four male dental students at KSU is a smoker. Having friends who are smokers was the most important risk factor associated with smoking. There is a general belief among dental students that public tobacco use is not well addressed in the dental college curriculum.

Socio-demographic correlates of six indicators of alcohol consumption: survey findings of students across seven universities in England, Wales and Northern Ireland

Background

This study assessed the prevalence of six alcohol consumption indicators in a sample of university students. We also examined whether students’ sociodemographic and educational characteristics were associated with any of the six alcohol consumption indicators; and whether associations between students’ sociodemographic and educational characteristics and the six alcohol consumption indicators differed by gender.

Methods

A cross-sectional study of 3706 students enrolled at 7 universities in England, Wales and Northern Ireland. A self-administered questionnaire assessed six alcohol consumption measures: length of time of last (most recent) drinking occasion; amount consumed during last drinking occasion; frequency of alcohol consumption; heavy episodic drinking (≥ 5 drinks in a row); problem drinking; and possible alcohol dependence as measured by CAGE. The questionnaire also collected information on seven relevant student sociodemographic characteristics (age, gender, academic year of study, current living circumstances - accommodation with parents, whether student was in intimate relationship, socioeconomic status of parents - parental education, income sufficiency) and two academic achievement variables (importance of achieving good grades at university, and one’s academic performance in comparison with one’s peers).

Results

The majority of students (65% of females, 76% of males) reported heavy episodic drinking at least once within the last 2 weeks, and problem drinking was prevalent in 20% of females and 29% of males. Factors consistently positively associated with all six indicators of alcohol consumption were male gender and perceived insufficient income. Other factors such as living away from home, being in 1^st or 2^nd year of studies, having no intimate partner, and lower academic achievement were associated with some, but not all indicators of alcohol consumption.

Conclusions

The high level of alcohol consumption calls for regular/periodic monitoring of student use of alcohol, and for urgent preventive actions and intervention programmes at the universities in the UK.

Next day effects of naturalistic alcohol consumption on tasks of attention

OBJECTIVES

The aim of this study was to examine the next day effects of alcohol consumption on a range of attention tasks.

METHODS

The study followed a counterbalanced repeated measure design, with participants tested the morning following normal/usual alcohol consumption and again the morning after no alcohol consumption. Participants were 48 social drinkers (15 men and 33 women), who performed attention tests at 9 am, 11 am, or 1 pm. Performance was assessed by tasks measuring sustained attention, divided attention, selective attention, and spatial attention and by the Stroop test.

RESULTS

The morning after alcohol consumption, a significantly higher proportion of missed targets was observed (F(1, 40) = 6.43, p < 0.05) in the sustained attention task. In the Stroop test, participants responded significantly slower (F(1, 42) = 8.72, p < 0.005) in the interference condition (when naming the color of the ink of the words) the morning after alcohol consumption. In the selective attention task, the consumption of alcohol the night before eliminated the robust distance by compatibility interaction, which was observed the morning after no alcohol consumption (F(1, 43) = 10.41, p < 0.01). No influence of alcohol was observed in the divided attention test nor in the spatial attention task.

CONCLUSION

Alcohol consumption has a negative impact on some but not all facets of attentional processing the morning after a normal nights drinking.

Personalised normative feedback for preventing alcohol misuse in university students: Solomon three-group randomised controlled trial

BACKGROUND

Young people tend to over-estimate peer group drinking levels. Personalised normative feedback (PNF) aims to correct this misperception by providing information about personal drinking levels and patterns compared with norms in similar aged peer groups. PNF is intended to raise motivation for behaviour change and has been highlighted for alcohol misuse prevention by the British Government Behavioural Insight Team. The objective of the trial was to assess the effectiveness of PNF with college students for the prevention of alcohol misuse.

METHODOLOGY

Solomon three-group randomised controlled trial. 1751 students, from 22 British Universities, allocated to a PNF group, a normal control group, or a delayed measurement control group to allow assessment of any measurement effects. PNF was provided by email. Participants completed online questionnaires at baseline, 6- and 12-months (only 12-months for the delayed measurement controls). Drinking behaviour measures were (i) alcohol disorders; (ii) frequency; (iii) typical quantity, (iv) weekly consumption; (v) alcohol-related problems; (vi) perceived drinking norms; and (vii) positive alcohol expectancies. Analyses focused on high-risk drinkers, as well as all students, because of research evidence for the prevention paradox in student drinkers.

PRINCIPAL FINDINGS

Follow-up rates were low, with only 50% and 40% responding at 6- and 12-months, respectively, though comparable to similar European studies. We found no evidence for any systematic attrition bias. Overall, statistical analyses with the high risk sub-sample, and for all students, showed no significant effects of the intervention, at either time-point, in a completed case analysis and a multiple imputation analysis.

CONCLUSIONS

We found no evidence for the effectiveness of PNF for the prevention of alcohol misuse and alcohol-related problems in a UK student population.

The epidemiology of alcohol consumption and misuse among Chinese college students

AIMS

To understand alcohol-related risk behaviours among Chinese college students.

METHODS

As part of the first China National Youth Risk Behaviour Survey, undertaken in 2009, 52,150 students at 119 colleges were randomly sampled. Information was obtained from self-administered questionnaires.

RESULTS

Prevalences were: lifetime drinkers 80.8%, current drinkers 49.3% (drank alcohol in past 30 days) and binge drinkers 23.5% ('binge drinkers' reporting at least five alcoholic drinks on a single occasion at least six times during the past 30 days). Multinomial logistic analysis revealed the contribution of sociodemographic factors to three high-risk drinking behaviours: odds ratio (95% confidence interval) = 3.64 (2.69-4.60) with frequent drinking; 3.27 (1.82-4.72) with binge drinking; and 5.48 (3.20-7.77) with heavy binge drinking. These three rates were greater among males than females, in the Western more than the Eastern region, among students living off-campus and among those whose mothers had higher education. Heavy drinking was linked to lower academic self-rating.

CONCLUSION

There is a trend towards risky drinking among Chinese college students. Measures such as a minimum drinking age, advertisement restrictions, taxation, drunk-driving penalties and campaigns to heighten public awareness of alcohol-related health risks should be instituted in order to improve the situation on college campuses where alcohol abuse is particularly prevalent.

Drinking at European universities? A review of students' alcohol use

BACKGROUND

High volumes of alcohol consumption and risky single occasion drinking (RSOD) among university students have been shown to be associated with considerable harm to both those who consume alcohol and their fellow students. The vast majority of these studies are based on US and Canadian samples.

AIM

The present article provides an overview of the characteristics of alcohol-consuming university students in Europe.

METHOD

65 relevant articles published within the last 20years using European student populations could be identified.

RESULTS

Sociodemographic, individual, social, and university-related characteristics associated with alcohol consumption patterns could be identified. Male students, in particular, tended to consume alcohol more often and in higher quantities, including RSOD. Students consumed alcohol chiefly during social gatherings and for social and enhancement motives. Those without family obligations and those living alone, with roommates or in areas with a high density of students were more likely to consume alcohol in higher quantities, and to engage in RSOD. Students tend to overestimate the extent of their fellow students' alcohol consumption.

CONCLUSIONS

Health promotion and prevention efforts which focus on these characteristics (i.e., gender, drinking motives, living conditions and social norms), and which have been successful and evaluated among university students in the US and Canada, may also be very promising for their European counterparts.

Tobacco, alcohol and drug use among dental undergraduates at one English university in 1998 and 2008

OBJECTIVE

To estimate the prevalence of tobacco, alcohol and drug use among dental undergraduates at one English university in 2008, and compare these with prevalence in 1998.

DESIGN

Cross-sectional survey using an anonymous self-report questionnaire.

SUBJECTS AND METHODS

In 2008 all 384 dental undergraduates at one English university were sent a questionnaire in order to obtain data on the frequency and amount of tobacco, alcohol, cannabis and other illicit drugs used before and during their time as a dental undergraduate. The same survey had been conducted on dental undergraduates at the university 10 years earlier.

RESULTS

Tobacco smoking was reported by 27% of males and 13.5% of females, a reduction from 1998 (42% of males and 32% of females) being significant among females. 63% of males and 69.5% of females reported drinking alcohol: significantly fewer than in 1998 (82% males and 90% females). Binge drinking was reported by 69.5% of males compared to 56% in 1998. In females 66% binged compared to 58.5% in 1998. The increase in males was significant. 62% of males and 68% of females had never used cannabis compared to 38% in males and 50.5% of females in 1998, a significant reduction. A significant reduction in amphetamine use was reported among both male and female undergraduates in 2008 compared to 1998 and a significant increase in amyl nitrate use was reported by females. Reported illicit drug use was associated with alcohol drinking, and particularly with tobacco use.

CONCLUSION

Dental undergraduates at one English university in 2008 when compared to those in 1998 are reported to be significantly less likely to drink alcohol, use cannabis and amphetamines. If female, they are significantly less likely to smoke tobacco and overestimate the number of units of alcohol they can safely consume in a week, but more likely to use amyl nitrate. If male, those who drink alcohol are significantly less likely to drink at a level of increased risk, but more likely to binge drink.

Social norms interventions to reduce alcohol misuse in university or college students

BACKGROUND

Drinking is influenced by youth (mis)perceptions of how their peers drink. If misperceptions can be corrected, young people may drink less.

OBJECTIVES

To determine whether social norms feedback reduces alcohol misuse in university or college students.

SEARCH STRATEGY

Cochrane Drugs and Alcohol Group Register of Trials; Central; MEDLINE; EMBASE; PsyInfo; CINAHL (up to March 2008).

SELECTION CRITERIA

RCT or cluster RCT that evaluate social normative intervention with no intervention, alcohol education leaflet or other non-normative feedback intervention

DATA COLLECTION AND ANALYSIS

2/3 authors extracted data. Included studies were assessed against criteria indicated in the Cochrane Reviewers Handbook version 5.0.0.

MAIN RESULTS

Twenty-two studies were included (7,275 participants).Alcohol related problems: Significant reduction with Web/computer feedback (WF) (SMD -0.31 95% Cl -0.59 to -0.02), three studies, 278 participants. No significant effect of mailed feedback (MF), individual face-to-face feedback (IFF) or group face-to-face feedback (GFF).Peak Blood Alcohol Content (BAC) : Significant reduction with WF (SMD -0.77 95% Cl -1.25 to -0.28), two studies, 198 participants. No significant effect of MF or IFF.Drinking Frequency: Significant reduction with WF (SMD -0.38 95% Cl -0.63 to -0.13), two studies, 243 participants and IFF (SMD -0.39 95% Cl -0.66 to -0.12), two studies, 217 participants. No significant effect of MF.Drinking Quantity: Significant reduction with WF (SMD -0.35 95% Cl -0.51 to -0.18), five studies, 556 participants and GFF (SMD -0.32 95% Cl -0.63 to -0.02) three studies, 173 participants. No significant effect of MF or IF.Binge drinking: Significant reduction with WF (SMD -0.47 95% Cl -0.92 to -0.03) one study, 80 participants, IFF (SMD -0.25 95% Cl -0.49 to -0.02) three studies, 278 participants and and GFF (SMD -0.38 95% Cl -0.62 to -0.14) four studies, 264 participants. No significant effect for MF.BAC: No significant effect of MF and IFFDrinking norms: Significant reduction with WF (SMD -0.75 95% Cl -0.98 to -0.52 ) three studies, 312 participants.

AUTHORS' CONCLUSIONS

WF and IFF are probably effective in reducing alcohol misuse. No direct comparisons of WF against IFF were found, but WF impacted across a broader set of outcomes and is less costly so therefore might be preferred. Significant effects were more apparent for short-term outcomes (up to three months). For mailed and group feedback, and social norms marketing campaigns, the results are on the whole not significant and therefore cannot be recommended.

Canadian dental students' perceptions of stress and social support

This study explored the relationship between dental school stress and social support reported by undergraduate students in a Canadian dental school. Students completed questionnaires comprised of Dental Environment Scale stress items, social support measures evaluating perceived contact and two proxy measures of social support (marital status and living arrangement). Sixty-two per cent of undergraduate students in all four academic years participated in the study conducted in March--April 2005. Second-year students living with parents had significantly higher adjusted total stress scores (P < 0.001), whilst fourth-year students living with roommates had significantly lower total adjusted stress scores (P = 0.008). Social support systems utilised by students included teacher, parental, student and relationship support. Students who received more support from teachers and from students inside and outside dental school had lower adjusted total stress scores. Multiple regression analysis assessing the effect of social support on total adjusted stress scores identified two significant variables after adjustment: second-year students living with parents (P < 0.001) and low teacher support (P = 0.032). This study identified social support and proxy measures as significant predictors of dental school stress in Canadian dental students. Further studies are needed to elucidate the role of social support and proxy measures as potential dental school stress alleviators.

Changes in undergraduate student alcohol consumption as they progress through university

Background

Unhealthy alcohol use amongst university students is a major public health concern. Although previous studies suggest a raised level of consumption amongst the UK student population there is little consistent information available about the pattern of alcohol consumption as they progress through university. The aim of the current research was to describe drinking patterns of UK full-time undergraduate students as they progress through their degree course.

Method

Data were collected over three years from 5895 undergraduate students who began their studies in either 2000 or 2001. Longitudinal data (i.e. Years 1–3) were available from 225 students. The remaining 5670 students all responded to at least one of the three surveys (Year 1 n = 2843; Year 2 n = 2219; Year 3 n = 1805).

Results

Students reported consuming significantly more units of alcohol per week at Year 1 than at Years 2 or 3 of their degree. Male students reported a higher consumption of units of alcohol than their female peers. When alcohol intake was classified using the Royal College of Physicians guidelines [1] there was no difference between male and females students in terms of the percentage exceeding recommended limits. Compared to those who were low level consumers students who reported drinking above low levels at Year 1 had at least 10 times the odds of continuing to consume above low levels at year 3. Students who reported higher levels of drinking were more likely to report that alcohol had a negative impact on their studies, finances and physical health. Consistent with the reduction in units over time students reported lower levels of negative impact during Year 3 when compared to Year 1.

Conclusion

The current findings suggest that student alcohol consumption declines over their undergraduate studies; however weekly levels of consumption at Year 3 remain high for a substantial number of students. The persistence of high levels of consumption in a large population of students suggests the need for effective preventative and treatment interventions for all year groups.

An international review of tobacco smoking among dental students in 19 countries

This study was conducted as a systematic review of all modern literature describing the prevalence of tobacco smoking among dental students. An electronic keyword search of appropriate terms was initially undertaken to identify relevant material, after which the reference lists of manuscripts were also examined to locate additional publications. A total of 27 studies from 19 countries were identified. The earliest manuscripts appeared in 1970, with the most recent being published in 2006. From a global perspective, our review suggests that tobacco smoking is relatively uncommon among contemporary dental students in Australia, Brazil, Canada, Great Britain and the United States. This is not surprising however, as it has previously been noted that dentists generally smoke at one of the lowest rates among all health professionals, and much lower than that of the communities in which they live. Somewhat discouragingly, we did find that smoking remains quite common among dental students in countries such as Greece, Serbia, Romania and Hungary. Given the fact that some of the student body continue to smoke tobacco, it is clear that more aggressive tobacco-specific measures should become a mandatory component of global dental education in future years.

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.

Emotional intelligence and stress coping in dental undergraduates--a qualitative study

OBJECTIVE

To explore how dental undergraduates with different levels of emotional intelligence (EI) cope with stress.

DESIGN

Qualitative unstructured depth interviews.

SETTING

A dental teaching hospital in the UK, 2002.

SUBJECTS AND METHODS

Subjects selected from the undergraduate population of a 5-year dental degree course. A questionnaire survey was carried out to determine the EI scores of the subjects. In each year of study, subjects were divided into low and high EI groups at the median score. From each EI group in each year, one male and one female subject were recruited.

DATA COLLECTION

Unstructured face-to-face interviews.

DATA ANALYSIS

Transcribing, sifting, indexing and charting data according to key themes.

RESULTS

10 males and 10 females with low and high EI, representing all 5 years of study were interviewed. The experience of stress, expressed in emotional terms, ranged from anger and frustration to hatred. Four sets of coping strategies, adopted at varying degrees according to EI, were identified. High EI students were more likely to adopt reflection and appraisal, social and interpersonal, and organisation and time-management skills. Low EI students were more likely to engage in health-damaging behaviours.

CONCLUSIONS

Future research needs to establish whether the enhancement of EI in dental students would lead to improved stress-coping, and better physical and psychological health.

A comparison of sensation-seeking between dental and biological science students

AIM

The aim of this study was to compare sensation-seeking behaviour amongst dental students and age-, sex-matched students studying for a standard 3-year degree in biological sciences at the Manchester University.

METHODS

A total of 268 sensation-seeking questionnaires were distributed to second- and third-year male and female dental and biological science students, studying for a degree at the University of Manchester. Each questionnaire was scored against Zuckerman's sensation-seeking scale.

RESULTS

A total of 268 questionnaires were distributed, 175 were returned. The return rate was 65%. The primary findings were: Biological Science students were more sensation-seeking in the dimensions of disinhibition and experience-seeking than dental students (P < 0.05). There was a significant gender bias in sensation-seeking. Males were significantly more sensation-seeking than females in both courses (P < 0.05). Males in both courses had similar sensation-seeking tendencies (NS). Females in the biological sciences course were less inhibited than their dental counterparts (P < 0.05).

CONCLUSIONS

There was a clear difference in sensation-seeking within and between groups of dental students and students studying biological sciences.

Alcohol and drug use among vocational dental practitioners

OBJECTIVE

This study was designed to investigate the prevalence of alcohol and drug use in vocational dental practitioners (VDPs).

DESIGN

Anonymous self-report questionnaire.

SUBJECTS AND METHODS

All UK vocational dental practitioners (n = 719) who started practice in the summer of 1999 were questioned on their use of alcohol, tobacco, cannabis and other illicit drugs whilst a VDP and before graduation.

RESULTS

Eighty-nine per cent of males and 88% of females reported alcohol use. Of these, 35% of males and 36% of females drank above sensible levels (up to 21 units per week for males, 14 units for females), with 48% of males and 52% of females "binge drinking". Thirty-three per cent of respondents reported cannabis use whilst a VDP. Regular drug use (use at least once a month) other than cannabis whilst a VDP was found to be highest among males, with regular ecstasy use reported by 4% and regular cocaine use reported by 2%. Regular tobacco use (ten or more cigarettes per day) was reported by 9% of VDPs. Regular tobacco users were found to be six times more likely to use cannabis on a regular basis, three times more likely to use ecstasy on a regular basis and four times more likely to use cocaine on a regular basis than those VDPs who reported non regular tobacco use.

CONCLUSION

VDPs are drinking above sensible limits, binge drinking, using tobacco and indulging in illicit drug use to a degree that will cause health problems. However, use of all substances had reduced since qualification.

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.
