About DEBRA

The German Study on Tobacco Use (DEBRA) is a bi-monthly representative, face-to-face household survey on the use of tobacco and alternative nicotine delivery systems (ANDS, such as e-cigarettes and heated tobacco products) in the German population. The study is coordinated by the Addiction Research and Clinical Epidemiology unit at the Institute of General Practice of the Heinrich-Heine-University Düsseldorf. The study has been funded by the German Ministry of Health (2019 – current) and the Ministry for Innovation, Science and Research of the German Federal State of North Rhine-Westphalia (2016 – 2019).

Current national statistics

The DEBRA study collects nationally representative data on the use of tobacco and ANDS in the German population. Some key indicators are graphically presented and regularly updated on this website.

Prevalence of current tobacco smokers in the German population

Prevalence of current e-cigarette use in the German population

Prevalence of e-cigarette use in current tobacco smokers and recent ex-smokers

Prevalence of current e-cigarette use by age categories and year of data collection

"The DEBRA study monitors the use of tobacco and alternative nicotine delivery systems in the German population."

Univ.-Prof. Daniel Kotz about the DEBRA-Study

Background of DEBRA

The prevalence of tobacco smoking in Germany is still at a very high level (nearly 30%), and the use of alternative nicotine delivery systems (ANDS) has been increasing in the population. The World Health Organisation (WHO) recommends monitoring the use of tobacco and ANDS on a national level to support implementation of the WHO Framework Convention on Tobacco Control and reduce tobacco-related harm. The DEBRA study addresses this recommendation by tracking key variables of patterns and trends in the use of tobacco and ANDS in Germany. Furthermore, the study collects data on relevant associated factors, such as socioeconomic background, alcohol consumption, and mental health. DEBRA will thereby provide nationally representative information for policy health strategies and future scientific studies.

Method

Multi-stage, multi-stratified, random probability sampling

German population aged 14+ years

Bi-monthly representative sample ~N=2,000
(June 2016 – ongoing)

Computer-assisted face-to-face interview at baseline

Computer-assisted telephone interview at 6 months
follow-up (tobacco smokers only)

Methodology of DEBRA

The DEBRA study started in June 2016 and consists of cross-sectional, computer-assisted household interviews in people aged 14 years and older. Every two months a new, representative sample of approximately 2,000 respondents will complete the survey every two months. Per wave, about 500-600 respondents identify themselves as current daily or occasional tobacco smokers or recent ex-smokers (quit attempt during last 12 months). At baseline and six months later, this group will answer detailed questions about their use of tobacco and ANDS, including urges to smoke, motivation to stop, rates, smoking, duration and success of quit attempts, internal and external triggers of quit attempts, use of behavioural and pharmacological cessation aids, and attitudes towards tobacco control policies. Smokers and recent ex-smokers are asked to complete a telephone survey 6 months later.
