Objective: To estimate the effectiveness of a short-term educational-counseling worksite program focused on lipid intake, by monitoring the possible change on nutrition knowledge and eating habits.
Methods: an 8-week educational program based on the Health Belief Model was implemented in a honey packaging and sales company in Greece. 20 out of the 29 employees initially enrolled completed the program. Knowledge level and eating habits were evaluated prior and after the intervention by the "Nutrition Knowledge Questionnaire" and the "Food Habits Questionnaire". ANOVA, Spearman rho test and paired Wilcoxon test were employed in statistical analysis.
Results: Non smokers and those with higher educational level had healthier eating habits. Knowledge following the intervention was significantly improved concerning recommendations and basic food ingredients but as far as eating habits were concerned, scores were not improved significantly, while intake of fried food was increased.
Conclusions and implications: Short-term interventions may produce substantial improvement in knowledge but not necessarily modifications in unhealthy eating habits.
