No results posted yet for this study

Summary

The goal of this observational study is to learn about dietary quality and barriers to healthy eating among older adults who participate in the Los Angeles County Food Rx Produce Distribution Program. The study will also evaluate whether a newer dietary assessment tool, the Global Diet Quality Questionnaire (GDQQ), performs similarly to an established dietary assessment tool, the Mediterranean Diet Scale (PREDIMED MDS), in measuring diet quality among adults aged 60 years and older.

The main questions it aims to answer are:

* Is the GDQQ associated with diet quality scores measured by the PREDIMED Mediterranean Diet Scale?
* Does the GDQQ predict self-reported body mass index (BMI) as well as or better than the PREDIMED Mediterranean Diet Scale?
* What barriers and facilitators influence healthy eating and participation in produce distribution programs among older adults?

Participants will:

* Complete questionnaires about their dietary habits, demographic characteristics, and food access experiences.
* Complete two dietary quality assessment tools: the PREDIMED Mediterranean Diet Scale and the Global Diet Quality Questionnaire.
* If randomly selected, participate in a one-time semi-structured interview to discuss healthy eating, food access, experiences with produce distribution events, and challenges to improving dietary quality.
