World Health Survey [hh/whs]
The 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 Global School-based Student Health Survey known as (GSHS) was introduced by World Health Organization in collaboration with Centers for Diseases control (CDC) in USA , the aim of this survey is to obtain baseline information to monitor the prevalence of important health risk behaviors and protective factors among students in following aspects : Dietary behaviors, Violence and unintentional injury, HIV-related knowledge, Hygiene, Tobacco use, Physical activity, Protective factors.
The GSHS was implemented in Libya, in February 2007 in 50 schools in which students of age from 13 to 15 are taught at school grades 7th, 8th, 9th. The sample was drawn through computerized process by CDC in two-stage cluster sample design used to select schools with probability proportional to school enrolment size , and classes were randomly selected. The Questionnaire was translated in to Arabic language and modified to be understandable to students; The total number of questions was 66. The answer sheets were designed to be filled by students in very simple way by using pencils to fill circle to answer each question. The survey was anonymous, so that students can express them selves and answer questions in complete privacy. The total number of students surveyed was 2242 male and female students .The data was processed by CDC and analyzed in same center using EPI INFO 2005, a software package that capable for analyzing complex data.

Sampling
The 2007 Libya GSHS employed a two-stage cluster sample design to produce a representative sample of students in GRADES 7-9. The first-stage sampling frame consisted of all schools containing any of GRADES 7-9. 2700 Schools were eligible to participate.schools were selected to participate with probability proportional to school enrolment size. 50 schools were selected to participate in the Libyan GSHS.
The second stage of sampling consisted of randomly selecting intact classrooms (using a random start) from each school to participate. All classrooms in each selected school were included in the sampling frame. All students in the sampled classrooms were eligible to participate in the GSHS.
The school response rate was 100 %, the student response rate was 98%, and the overall response rate was 98%.
A weighting factor was applied to each student record to adjust for non-response and for the varying probabilities of selection.
Survey instrument
The GSHS uses a standardized scientific sample selection process; common school-based methodology; and core questionnaire modules, core-expanded questions, and country-specific questions that are combined to form a self-administered questionnaire that can be administered during one regular class period.
For the 2007 Libya GSHS, 2,242 questionnaires were completed in 50 schools. The Libya GSHS questionnaire contained 66 questions (35 questions from core questionnaire and 31 questions from core - expanded and country - specific questions ) addressing the following topics:
- Dietary behaviours
- Hygiene
- Violence and unintentional injury
- Tobacco use
- HIV-related knowledge
- Physical activity
- Protective factors
The questionnaire was developed by Secretariat of Health & environment – Health Information& documentation Centre and translated in to Arabic language and tested before the start of the survey.

Survey administration occurred from 4 - February 2007 to 12- march 2007. Survey procedures were designed to protect student privacy by allowing for anonymous and voluntary participation. Students completed the self-administered questionnaire during one classroom period and recorded their responses directly on a computer-scannable answer sheet. 20 Survey Administrators were specially trained to conduct the GSHS. All necessary arrangement were made with secretariat of education at all levels and schools contacted by survey administrators for the day and time suitable to selected classes.
Data processing
The data set was cleaned and edited for inconsistencies. Missing data were not statistically imputed. Software that takes into consideration the complex sample design was used to compute prevalence estimates and 95% confidence intervals. GSHS data are representative of all students attending GRADES 7 – 9 in Libya.
