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.
This report describes results from the first Global School-based Student Health Survey (GSHS) conducted in Trinidad and Tobago by the Ministry of Health and Ministry of Education from 19-30, April 2007.
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; and
- Allow countries, international agencies, and others to make comparisons across countries and within countries regarding the prevalence of health behaviours and protective factors

Sampling
The 2007 Trinidad and Tobago GSHS employed a two-stage cluster sample design to produce a representative sample of students in Forms 1-4. The first-stage sampling frame consisted of all schools containing any of Forms 1-4. (25 schools in Trinidad and 7 schools in Tobago). Schools were selected with probability proportional to school enrolment size. 32 schools were selected to participate in the Trinidad and Tobago 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. Students completed the 66 item self- administered questionnaire during one classroom period. The questionnaire addressed the following areas: respondent demographics, alcohol and other drug use; BMI and dietary behaviours; hygiene-related behaviours; mental health issues; physical activity; protective factors; sexual behaviours that contribute to HIV infection, other STI,and unintended pregnancy; tobacco use; and violence and unintentional injury. Survey procedures were designed to protect students' privacy by allowing for anonymous, confidential, and voluntary participation.
The Global School-Based Student Health Survey (GSHS), was completed by 2969 students in 32 schools in Trinidad and Tobago during 2007. The school response rate was 100%, the student response rate was 78%; 2998 of the 3,786 sampled students completed questionnaires The data set was cleaned and edited for inconsistencies (2969 questionnaires were usable after data editing) and the overall response rate was 78%.
A weight has been associated with each questionnaire to reflect the likelihood of sampling each student and to reduce bias by compensating for differing patterns of non-response. A weighting factor was applied to each student record to adjust for non-response and for the varying probabilities of selection.
The weighting formula used for calculation was
W1 = the inverse of the probability of selecting the school
W2 = the inverse of the probability of selecting classrooms,
f 1 = a school–level non-response adjustment factor,
f 2 = a student-level non-response adjustment factor calculated by classroom, and
f 3 = a post stratification adjustment factor calculated by sex within grade.
Survey instrument
The Trinidad and Tobago GSHS questionnaire contained 66 questions, fifty four (54) questions (1-54) were from the core questionnaire modules and twelve (12) questions (55-66) were the core expanded GSHS questions and country–specific questions. The core GSHS questionnaire consists of all core questionnaire addressing the following topics:
- Alcohol and other drug use
- Dietary behaviours
- Hygiene
- Mental health
- Physical activity
- Protective factors
- Sexual behaviours that contribute to HIV infection, other STI, and unintended pregnancy
- Tobacco use
- Violence and unintentional injury

Survey administration occurred from 19 April 2007 to 30 April 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. Approximately, 53 survey administrators were specially trained to conduct the GSHS.
Data processing
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. Computer packages like SUDAAN, SPSS and EPI INFO were used to analyse the data.

- Public health and scientific advancement are best served by an open and timely exchange of data and data analyses.
- The privacy of participating schools and students must be protected.
- Data quality must be maintained.
