Diet quality in older adults and how two dietary tools compare

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study examines dietary quality among adults aged 60 and older who regularly participate in the Los Angeles County Food Rx Produce Distribution Program. Participants will complete two dietary assessment tools, the PREDIMED Mediterranean Diet Scale and the Global Diet Quality Questionnaire, to see how well they align and which better relates to self-reported BMI. The research also explores barriers and facilitators to healthy eating and participation in produce distribution, using a mixed-methods approach to capture both quantitative scores and participant perspectives. The study aims to validate and compare dietary assessment methods and to inform culturally appropriate nutrition interventions for food-insecure older adults. The project is led by UCLA with support from NIA and NCATS and is conducted at a Los Angeles-based Food Rx site.

  * Be 60 years of age or older
  * Be a regular attendee (i.e., more than one visit) at L.A. County Food Rx produce distribution events
  * Be able to communicate in English or Spanish, as these are the languages in which study materials and interviews are available
  * Be able to provide informed consent and complete the brief study activities These criteria reflect the study's focus on older adults at increased risk for chronic disease due to food insecurity and poor diet quality. English and Spanish were selected based on the primary languages spoken at Food Rx distribution sites and the capacity of the study team to support accurate, culturally sensitive data collection.

Exclusion Criteria:

* Individuals will be excluded if they:

  * Are younger than 60 years old
  * Are first-time attendees at the produce distribution site (i.e., not familiar with program operations)
  * Are unable to understand or communicate in English or Spanish
  * Are unable to provide informed consent or complete the questionnaires or interview due to cognitive or physical limitations Language and participation history were included as exclusion criteria to ensure participant familiarity with the setting and the ability to engage meaningfully in data collection. ose who cannot provide informed consent will be excluded in accordance with ethical research protections for vulnerable adults.
