Previous history

• Need for an alcohol and drug policy for the Antwerp university and Colleges

=> Collaboration initiated by SODA (Antwerp Platform for consultation on drug problems) towards an alcohol and drug policy in the Antwerp university and colleges

• Difficult to reach a consensus on the strategy and approach

• => first “evidence” is needed by means of a large-scale survey in the involved students

4

Methodology: research questions• 10 research questions:

- What is the state of the art of the substance use in Antwerp students?- To what extent do so called typical manifestations of substance use in students occur (binge drinking, medication use during exams, …)?- Where and when does the substance use take place?- Which are the motives for substance use?- To what extent do problematic substance use and/or negative consequences of substance use occur?

5

Methodology: research questions- Is there a relationship between leisure time activities

and substance use?- Is there a relationship between the state of mind and

substance use?- Is there a relationship between personal

characteristics (sex, living situation, …) and substance use?

- To what extent are social services (as well inside as outside the setting of the university or college) known and are they used in case of questions and problems?

- To what extent is the theme of alcohol- and drugs a part of the study curriculum?

6

Methodology: used instruments

• Questionnaire elaborated by means of:

- validated instruments (AUDIT, CORE, DAST, GHQ, …)

- own questions, based on questions from other studies (for example leisure time activities)

• Pretest questionnaire in 10 students• Final questionnaire distributed among all Antwerp

students by intranet (BlackBoard) • A lot of attention was given to the announcement and

promotion

Students and alcohol: do they go hand in hand with one another?

“The university student generally has the reputation that he does not scorn alcohol. (…) Some even go that far to label the combination of beer and student as being fundamental.” (W. Prové - 1965)

14Students and alcohol: do they go hand in hand with one another?

“College students drink. No matter how you slice it, most people would agree with some version of that statement.” (Walters & Baer, 2006)

15

Alcohol: prevalence• Prevalence 2009:

– 96.8% has ever drunk alcohol (beer, wine, liquors, aperitif)– 92.4% has drunk alcohol during the last year– for each of the alcoholic drinks, there is an ever-use between

84.0% en 92.5%– For each of the alcoholic drinks the last year use was between

74.8% en 83.9%

Alcohol use is very current in students

… but these figures do not say anything concerning the possible problematic character of the alcohol use => frequencies of use and instruments to trace problematic use are needed

16

Alcohol: frequency

Strikingly more frequent use during the academic year and during holidays than during examination periods

>50% frequent beer users during academic year and holidays

Low frequencies of daily users during examination periods, which can be an indication of a small number of students with alcohol dependency (0.9% for beer).

User frequencies give indications but no clear picture of a possible problematic use.

17

Alcohol: problematic use measuredTwo validated instruments:• Alcohol Use Disorder Identification Test (AUDIT)

– self report-questionnaire– 10 questions on drinking pattern and experienced

consequences of alcohol use– Usefulness in adolescents and students is proven

• Quantitative norms British Medical Association– self report-question on the mean number of glasses of alcohol

drunk per week– risk-assessment of physical harm due to alcohol use:

• women: >14 glasses alcohol/week• men: >21 glasses alcohol/week• How many drinks containing alcohol do you usually drink weekly?…………drinks

19

AUDIT (1)

• How often do you have a drink containing alcohol?

- Never (0)- Monthly or less (1)- 2-4 times a month (2)- 2-3 times a week (3)- 4 or more times a week (4)

21

AUDIT (3)

• How often do you have six or more drinks on one occasion?

- Never (0)- Less than monthly (1)- Monthly (2)- Weekly (3)- Daily or almost daily (4)

29

AUDIT – How to interpret?

• Total scores of 8 or more are recommended as indicators of hazardous and harmful alcohol use, as well as possible alcohol dependence. (Applicable to women and elderly people from a total score of more than 5)

• AUDIT-scores in the range of 8-15 represent a medium level of possible alcohol problems, whereas scores of 16 and above represent a high level of possible alcohol problems.

• Total scores of 20 or above represent a high level of possible dependence.

Alcohol: problematic use (AUDIT) 

AUDIT-score Male students Female students

0-7 48.1% 80.7%

8-15 40.9% 17.6%

16-19 7.1% 1.1%

20-40 4.0% 0.6%

  (²=388.467; df=3; p<0.001)

Binge drinking

32

Alcohol: binge drinking  • Hot item in the media, but what is binge drinking?

• Binge drinking means drinking several glasses of alcohol in a short time with the intention to get drunk quickly.

On that point, there is a consensus, but unfortunately, there are many more differences concerning the definition…

33

Binge drinking: what’s in a name? 

1. Number of glasses per occasion?

USA: 4+ (♀) / 5+ (♂)

Europe: tendency to use higher numbers (6+/8+?)

2. What is an occasion?

Strongly culturally determined: closing hour pubs, drinking habits (for example dinner during hours with wine),…

It is important to come to a universal definition of binge drinking in the near future, with the BAC as a basis.

In our study: at least 4 standard glasses in 2 hours (women) and at least 6 standard glasses in 2 hours (men)

34Binge drinking: results 

• 0.3% means more or less 300 students

Frequency binge drinking

Percentage students

Percentage students (♂)

Percentage students (♀)

Never 43.6% 34.0% 51.6%

Less than monthly 35.7% 35.1% 36.4%

Monthly 13.0% 16.8% 9.8%

Weekly 7.4% 12.2% 3.5%

Daily or almost daily 0.3% 0.6% 0.1%

  (² = 174.471; df = 4; p < 0.001)

35

Binge drinking: results

• The more frequent binge drinking, the higher the risk of problematic use, measured by the AUDIT (rs =

0.72; p<0.001); approximately evenly strong in women and men.

36

37

Alcohol: other results• No relationship between age and alcohol use…• but between starting age and alcohol use: the lower the

starting age, the higher the risk to end up with problematic alcohol use

• Places where alcohol is used: pub, restaurant, parties and own place of residence. – Positive relation between frequency of visiting parties and pubs and

frequency of drinking beer – Positive relation between frequency of visiting parties and pubs and

frequency of drinking liquors

38

Alcohol: other results (2)

• Motives for alcohol use: sociability with friends (95.6%), to have fun (58.2%), because it is pleasant (57.1%), to relax (55.8%), to create a good atmosphere (50.0%), to get a good feeling (30.7%), to let off steam in case of stress (30.7%).

39

Alcohol: other results (3)

• Relationship between board membership of a student organisation and a higher frequency of alcohol use (beer and liquors)…

• Relationship between board membership of a student organisation and consumed quantity of alcohol: 14 glasses per week vs. 6 glasses per week

40

Alcohol: other results (4)

• Students who are board member of a student organisation have a 3 times higher risk of becoming problematic alcohol users

• Students living with peers have a higher alcohol use than students living with their parents (study in Antwerp and Amsterdam – Boot CRL, Rosiers JFM, Meijman FJ, Van Hal GFG, 2010).

41

Students living with peers and students living with their parents Hypotheses:

=> parental supervision

=> peer-influences

=> a common underlying characteristic (adventurous type)?

42Some conclusions• The bulk of students in Antwerp and Ghent do not

show characteristics of risky or problematic use• Though, problematic use is not that far away:

– 1/9 ♂ students shows signs of problematic alcohol use– Widespread binge drinking is risk-increasing

An information and sensibilisation campaign could be useful for all students

A minority of students needs advice and/or help!!! 3/10 students want more attention for the alcohol

and drugs theme in the study curriculum
