Tiivistelmä
Objective: The aim of this study was to gain insight into the understanding of genetics and perceptions on the ethical issues related to genotype disclosure of the participants in a nutrigenetic study.
Methods: A close-ended questionnaire was developed based on literature and discussions among the research group members. The questionnaire contained a -total of 33 questions, which were divided into 4 categories - demographics, knowledge assessment, concerns related to participation, and opinions on disclosure of information. Majority of the participants (250 out of 281) of a nutrigenetic study, in which effect of disclosing APOE allele status on lifestyle changes was studied, completed the questionnaire online following the informed consent process. The responses from the knowledge assessment and the concern categories were transformed into knowledge and concern scales, respectively, and analysed by descriptive statistical methods. The statistical associations between the categorical variables were determined using chi(2) test of independence. The relationship between the continuous variables was assessed using Pearson product-moment correlation coefficient and internal consistency of questions by Cronbach's alpha.
Results: No correlation was observed between the level of education and knowledge scores. About 10% of the participants thought that the genetic predisposition would be stressful to them and their family members.
Conclusions: Careful distribution of information before a nutrigenetic study supports understanding and reduces concerns of genetic susceptibility. In Finland, strong basic education is likely to have strengthened the trust in research process.
