The usefulness of Moynihan questionnaire in the evaluation of knowledge on healthy diet of patients undergoing cardiology rehabilitation

Abstract

Background. The aim of study was to test the usefulness of Moynihan questionnaire in the evaluation of knowledge on healthy diet of patients undergoing cardiology rehabilitation. Methods. We enrolled 51 patients (pts): 41 men and 10 women, mean age 67.97 + 11.2 years. The case study included: 21 pts that underwent coronary bypass surgery, 16 pts replaced plastic tube, 14 pts had surgery for the other reasons. All pts underwent nutritional investigation by a dietitian. Anthropometric and biochemical parameters were detected and, by the end, the Moynihan questionnaire was administrated. Pts underwent nutritional coaching, and questionnaire and dietary assessment were rechecked after 3 months. Results. At baseline, the mean Questionnaire score was 22.4 + 3.2 points, decreased to 20.6 + 3.1 points after 3 months (p<0.05). A detailed analysis of the questions showed that the major informations gaps were related to consumption of fruits and vegetables, consumption of fat and salt. In addition pts have acquired more general knowledge about food composition. Conclusions. The Moynihan questionnaire is an useful instrument of evaluation of dietary knowledge even in selected patients population. In the present study involving patients after cardiac surgery the main difficulties were related to high age of pts, the low cultural level and, mainly, to the post-surgery stress. However, an increase of correct answers as well as an increased knowledge about food composition were detected after educational intervention performed by the dietitian.
