World Health Survey [hh/whs]
The Global School-based Student Health Survey (GSHS) is a collaborative surveillance project designed to help countries measure and assess the behavioural risk factors and protective factors in 10 key areas among young people aged 13 to 17 years. The GSHS is a relatively low-cost school-based survey which uses a self-administered questionnaire to obtain data on young people's health behaviour and protective factors related to the leading causes of morbidity and mortality among children and adults worldwide. The GSHS was developed by the World Health Organization (WHO) in collaboration with United Nations' UNICEF, UNESCO, and UNAIDS; and with technical assistance from CDC.
As of December 2011, representatives from more than 107 countries have been trained and 73 countries have completed a GSHS. Twenty-nine countries have been trained but have not conducted their surveys because of insufficient funds, staff turnover, or other in-country barriers. More than 420,000 students have participated in a GSHS survey.
The 2007 Seychelles Global School-based Student Health Survey (GSHS) is a school-based survey conducted primarily among students aged 11-17 years. It is the most recent attempt to collect information on the prevalence of a wide range of risk behaviours in adolescents and related characteristics in Seychelles.
The purpose of the GSHS is to provide accurate data on health behaviours and protective factors among students to:
- Help countries develop priorities, establish programmes, and advocate for resources for school health and youth health programmes and policies;
- Establish trends in the prevalence of health behaviours and protective factors by country for use in evaluation of school health and youth health promotion when this is repeated in the future;
- Allow countries, international agencies, and others (8) to make comparisons between countries regarding the prevalence of health behaviours and protective factors.

Sampling
A two-stage cluster sample design was employed to produce a representative sample of all students in the country attending grades S1, S2, S3, S4, and S5. In Seychelles, grades S1 to S4 are mandatory and more than 80% of student also attend grade S5. All 13 public and private schools of Seychelles containing any of the S1-S5 grades were selected to participate in the survey. Based on a listing of all schools and classes, the sample of eligible schools and classes was produced by CDC. All classrooms in each selected school were included in the
eligible sampling frame. All students in the sampled classrooms were eligible to participate in the GSHS. For analysis, a weighting factor was applied to each student record to adjust for non-response and for the varying probabilities of selection.
Out of the 1,747 eligible students, 1,432 participated (a response rate of 82%). Five (0.3%) students present in school refused to complete the questionnaire. All the other non-participants were not in class on the day of the survey.
Data were weighted for non-response and for the varying probabilities of selection. Analyses were made using EPI INFO and STATA 10. 95% confidence intervals were calculated.
Survey instrument
The questionnaire included 70 questions, 41 questions from a set of standard core questions and 29 core-expanded questions (i.e. questions developed by GSHS but that are optional) and country-specific questions(questions that are developed locally), addressing the following topics: Demographics, dietary behaviours and overweight, physical activity and sedentary behaviours, tobacco use, alcohol and other drugs use, sexual behaviours that contribute to HIV infection, other sexually transmitted infections and unintended pregnancy, bullying, mental health, protective factors and pocket money.

The survey was administered from 1st to 10th of October 2007 in the whole country (i.e. the 3 main islands that account for more than 99% of the total population of Seychelles). The Ministry of Education provided the list of all schools and organized the necessary contacts. Approximately, 33 survey administrators (mostly student nurses and qualifed nurses) were specially trained to conduct the GSHS. Administrators were assigned to the participating schools and were responsible for the delivery and collection of all the survey documentation forms, answer sheets and questionnaires. One survey administrator was present in each participating class during the administration of the questionnaire: she or he introduced the survey to the students and was the only adult present in the class when students completed the questionmaire. Survey procedures were designed to protect student privacy by allowing for anonymous and voluntary participation. Students completed the selfadministered questionnaire during one classroom period and recorded their responses directly on a computerscannable one-page answer sheet. Students were informed on the aims of the survey and that they were free to participate. Most students took 45 to 60 minutes to complete the questionnaire.
Before completing the questionnaire, students had their weight and height measured with standard equipment and administrators wrote the values on a register. Students were asked to write down their weight and height values in the answer sheet. Overweight and obesity were defined according to the sex and age specific criteria of International Obesity Task Force (9).
Data processing
The data set was cleaned and edited for inconsistencies. Missing data were not statistically imputed. Analysis was done using the statistical software EPINFO and STATA version 10.0. Associations were computed with Spearman correlation coefficients. The prevalence estimates and 95% confidence intervals were calculated taking into consideration the complex sample design.
