The GABRIEL Advanced Surveys: study design, participation and evaluation of bias

Exposure to farming environments has been shown to protect substantially against asthma and atopic disease across Europe and in other parts of the world. The GABRIEL Advanced Surveys (GABRIELA) were conducted to determine factors in farming environments which are fundamental to protecting against asthma and atopic disease. The GABRIEL Advanced Surveys have a multi-phase stratified design. In a first-screening phase, a comprehensive population-based survey was conducted to assess the prevalence of exposure to farming environments and of asthma and atopic diseases (n = 103,219). The second phase was designed to ascertain detailed exposure to farming environments and to collect biomaterial and environmental samples in a stratified random sample of phase 1 participants (n = 15,255). A third phase was carried out in a further stratified sample only in Bavaria, southern Germany, aiming at in-depth respiratory disease and exposure assessment including extensive environmental sampling (n = 895). Participation rates in phase 1 were around 60% but only about half of the participating study population consented to further study modules in phase 2. We found that consenting behaviour was related to familial allergies, high parental education, wheeze, doctor diagnosed asthma and rhinoconjunctivitis, and to a lesser extent to exposure to farming environments. The association of exposure to farm environments with asthma or rhinoconjunctivitis was not biased by participation or consenting behaviour. The GABRIEL Advanced Surveys are one of the largest studies to shed light on the protective 'farm effect' on asthma and atopic disease. Bias with regard to the main study question was able to be ruled out by representativeness and high participation rates in phases 2 and 3. The GABRIEL Advanced Surveys have created extensive collections of questionnaire data, biomaterial and environmental samples promising new insights into this area of research.

HEALTH AND SAFETY ISSUES IN THE WORKPLACE: THE CASE OF CAMEROON TEA ESTATE (CTE), A RISK COMMUNICATION APPROACH

In 2002, motivated largely by the uncontested belief that the private sector would operate more efficiently than the government, the government of Cameroon initiated a major effort to privatize some of Cameroon’s largest, state-run industries. One of the economic sectors affected by this privatization was tea production. In October 2002, the Cameroon Tea Estate (CTE), a privately owned, tea-cultivating organization, bought the Tole Tea Estate from the Cameroon Development Corporation (CDC), a government-owned entity. This led to an increase in the quantity of tea production; however, the government and CTE management appear not to have fully considered the risks of privatization. Using classical rhetorical theory, Richard Weaver’s conception of “god terms” (or “uncontested terms”), and John Ikerd’s ethical approach to risk communication, this study examines risks to which Tole Tea Estate workers were exposed and explores rhetorical strategies that workers employed in expressing their discontent. Sources for this study include online newspapers, which were selected on the basis of their reputation and popularity in Cameroon. Analysis of the data shows that, as a consequence of privatization, Tole Tea Estate workers were exposed to three basic risks: marginalization, unfulfilled promises, and poor working conditions. Workers’ reactions to these risks tended to grow more emotional as management appeared to ignore their demands. The study recommends that respect for labor law, constructive dialogue among stakeholders, and transparency might serve as guiding principles in responding to the politics of privatization in developing countries.
