Effectiveness of Culinary Nutrition Workshops on the Mood and Nutritional Interest of Inpatients With Mental Disorder

Background Promoting healthy eating habits through nutrition education programs is crucial to improving the overall health of people with mental disorders. This study aims to assess the effectiveness of culinary nutrition workshops on the mood and nutritional interest of hospitalized adults with mental disorders (MD) from the acute psychiatric unit of two general hospitals in Catalonia, Spain. Methods A pilot randomized control trial (RCT) was conducted with MD inpatient. Participants were randomly assigned to two groups: the intervention group received weekly culinary nutrition workshops with flexible participation and the control group continued routinary care. The interest in nutrition was analysed with an ad hoc item pre and post-intervention period. Mood changes were studied with a visual analog scale and analysed pre- and post-intervention periods as well as before and after every session. An ad hoc questionnaire was also used to assess the satisfaction of participants with the intervention. The obtained data were analysed at both descriptive and inferential levels. Results We included 81 participants, with a mean age of 45.3 (SD: 17.0); 66.7% were women, with 41 assigned to the intervention group and 40 to the control group. At the end of every culinary nutrition workshop, a statistically significant improvement in mood was observed in the intervention group (5.9 vs. 7.4 points, p<0.001). However, there were no significant differences in mood changes between the control and intervention groups after the intervention period (control group: 1.0 vs. intervention group: 1.5, p=0.473), while the nutritional interest was significantly improved after the intervention period intergroups (control group: 4.1 vs. intervention group: 37.2, p<0.001). The intervention was excellently valued by the participants regarding content, space, and health professionals, and generated interest and motivation, with scores above 9 on all these items. Conclusion The improvement of interest in nutrition and the satisfaction of hospitalised people with MD with the nutrition culinary workshops emphasize the need to design more comprehensive RCTs in hospitals and rehabilitation centers.
