Outcome Measures

Primary Outcomes (1)

• Food literacy score assessed with the Food Literacy Questionnaire for Spanish older adults (FLQ-e)

  The Food Literacy Questionnaire for Spanish older adults (FLQ-e) consists of 41 items covering five domains of food literacy: (1) basic healthy eating, (2) label consultation and food selection, (3) meal planning and budgeting, (4) food safety, preparation and cooking, and (5) awareness of the influence of food on personal wellbeing. The questionnaire generates a total food literacy score ranging from 0 to 123 points. Based on this score, participants are classified into three levels of food literacy: low (0-41 points), medium (42-82 points), and high (83-123 points).

  From enrollment to the end of the intervention after 12 months

Secondary Outcomes (2)

• Dietary intake assessed by 3-day dietary record and nutrient analysis using DIAL software

  From enrollment to the end of the intervention at 12 months

• Physical activity level assessed with the International Physical Activity Questionnaire - Short Version (IPAQ-sv)
