Model of reciprocal relationships between health, health behaviour and educational achievement*. *Socio-economic factors serve as background factors with potential influence on all other factors in the model. 1.3. Aim of the Study This study assessed the association between health awareness, health behaviour and subjective health status and three educational achievement outcomes. It was hypothesised that indicators of positive health (high health awareness, low level of complaints, high level of subjective health and health conducive behaviours) would be associated with three positive academic outcomes (internal: the importance of good grades; comparative: performance relative to other students; external: actual achieved module mark/grade). This research seeks to contribute to the evidence base on the importance of health and health promotion for academic outcomes and therewith for academic institutions. 2. Methods 2.1. Data Collection Procedures Two cross-sectional studies were simultaneously undertaken among students from the University of Gloucestershire, UK during 2008–2009. Ethical approval was obtained from the university ethics committee after their review of the study design, tool, other research material, and participant information sheet which included a letter of invitation that highlighted that participation is voluntary. Both surveys employed a ‗universal sampling‘ technique where all students were invited to participate. The first study was a general student health survey [48]. The second study was a survey of students‘ satisfaction with different aspects of their learning and teaching experience. The responses to the questionnaires of both studies were subsequently linked together by using the student‘s registration number which participants provided when completing the questionnaires. The student‘s registration number was also used to link the questionnaires to the university database and import the student‘s
