Nutrition Knowledge of Elderly Women: Effect of Two Food and Nutrition Education Programs.

Objective: To compare the effect of two programs of Food and Nutrition Education (FNE) on the Nutrition knowledge of elderly women, Brazil.

Methods: Randomized field trial. Community-based elderly women over 60 years (n = 36) participated in a twelve-week intervention in either of two FNE programs: Psychopedagogical Program (PP) or Culinary Workshop Program (CWP). There were three moments of data collection in the study; pre-intervention knowledge data); post intervention and follow up (after 6 months upon intervention completion). A questionnaire about knowledge of food and Nutrition was administered at every data collection moment.

Results: In the analysis performed by the Generalized Estimation Equation Models (GEE) there was a significant interaction effect (P = 0.033) in the diabetes block in which the percentage of correct answers in the follow-up moment was higher compared to the pre-intervention moment in the CWP group (65.65% and 45.66%, respectively). In the knowledge blocks: total percentage of correct answers, hypertension, food processing, the evaluation effect was observed, regardless of the intervention performed.

Three blocks of knowledge, including the block of the total percentage of correct answers in knowledge in Nutrition, presented a significant evaluation effect, which suggests that the interventions were important for the gain of knowledge, regardless of the type of intervention performed. Elderly-focused FNE programs should include a methodology that encompasses recreational education activities, and practical activities, such as culinary workshops.
