Other Household Health Survey [hh/hea]
In December 1998, TFI convened a meeting in Geneva with the Centers for Disease Control and Prevention (CDC), the United Nations Children’s Fund (UNICEF), the World Bank and representatives from countries in each of the six WHO regions to discuss the need for standardized mechanisms to collect youth tobacco use information on a global basis. The outcome of this meeting was the development by WHO and CDC of a Global Tobacco Surveillance System, which uses the Global Youth Tobacco Survey (GYTS) as its data collection mechanism.
The GYTS is a school-based survey designed to enhance the capacity of countries to monitor tobacco use among youth and to guide the implementation and evaluation of tobacco prevention and control programmes. The GYTS uses a standard methodology for constructing the sampling frame, selecting schools and classes, preparing questionnaires, following consistent field procedures, and using consistent data management procedures for data processing and analysis. The information generated from the GYTS can be used to stimulate the development of tobacco control programmes and can serve as a means to assess progress in meeting programme goals. In addition, GYTS data can be used to monitor seven Articles in the WHO FCTC.
Sample survey data [ssd]
Individuals
Scope
GYTS is composed of 56 "core" questions designed to gather data on the following seven domains. The questionnaire also allows countries to insert their own country-specific questions.
- Knowledge and attitudes of young people towards cigarette smoking
- Prevalence of cigarette smoking and other tobacco use among young people
- Role of the media and advertising in young people’s use of cigarettes
- Access to cigarettes
- Tobacco-related school curriculum
- Environmental tobacco smoke (ETS)
- Cessation of cigarette smoking

Sampling
The Lebanon GYTS was a school-based survey of students in grades 7-9, conducted in 2005. A two-stage cluster sample design was used to produce representative data for Lebanon. At the first stage, schools were selected with probability proportional to enrollment size. At the second stage, classes were randomly selected and all students in selected classes were eligible to participate. The school response rate was 98.0%, the class response rate was 100%, the student response rate was 99.2% and the overall response rate was 97.2%. A total of 3,314 students aged 13-15 participated in the Lebanon GYTS.
Methodology
- School-based survey of students aged 13-15 years
- Multistage sample design with schools selected proportional to enrollment size
- Classrooms chosen randomly within selected schools
- All students in selected classes eligible for participation
- Anonymous and confidential self-administered questionnaire
- Countries may add questions to the questionnaire
- Computer-scannable answer sheets
- Requires only 30-40 minutes to administer
- Fieldwork conducted in 6-8 weeks
- Country-level data with regional-level stratification possible
- Core questionnaire (standard set of survey questions used in all locations)
Data collection

Agreement for national data collection
Before collecting data, all Research Coordinators (RCs) must participate in a training workshop, organized by the WHO Regional Office (RO) in collaboration with other partners, to ensure a common methodology and unified procedures. This training assures continuity across the regions; consistency in sample design, selection procedures, and questionnaire development (ensuring the core remains intact); and uniformity in field procedures for data collection.
Organization of the Training Workshop
- The ROs and CDC jointly set a date and name a place for the training workshop.
- The ROs in cooperation with CDC, and associate partners when applicable, arrange the logistics and timing for the regional GYTS training workshops.
- The ROs and CDC prepare all materials for the training; send school enrollment files and data needs to countries; and ask each country to prepare a short presentation for the workshop, describing the country's educational system and its efforts to control tobacco use among youth.
- The ROs in collaboration with CDC, and associate partners when applicable, will conduct the GYTS training workshop.
- CDC and ROs, and associate partners when applicable, will work with each country to develop the sample frame and design. CDC in collaboration with ROs, and associate partners when applicable, works with countries on all issues concerning the sample design and sample selection.
Collection of National Data
At the end of the training workshop, the RCs for each participating survey site or country will have a clear understanding of all issues concerning GYTS implementation. The national government ensures that survey data collection is completed within six months after the training workshop. To ensure successful collection of national data, the following steps are taken:
- The RO and, when applicable, associate partners follow up with the countries on all budget issues.
- The RO, CDC and, when applicable, associate partners work with the countries to review their questionnaire.
- CDC and the RO collaborate with the countries on all issues pertaining to sample selection.
- CDC provides the countries and survey sites with survey supplies (e.g. answer sheets and header sheets).
- CDC provides ongoing technical assistance to the ROs and RCs during the implementation phase.
Data processing
After completing the data collection phase of GYTS, the RCs send the survey forms (answer and header sheets and school and classroom level forms) to CDC for data processing. For each survey site, the sheets are optically scanned, a data file is prepared and edited, and survey weight adjustments are applied. CDC staff and the RC and RO interact throughout the cleaning and editing of data files. After the data file is completed, CDC produces 100+ weighted frequency tables and 100+ preferred tables. CDC drafts a one-page fact sheet highlighting the main GYTS findings. The final data file, tables, and fact sheet are sent to the corresponding RC via e-mail and as hard copy.
