About this trial

The goal of this clinical trial is to evaluate the feasibility, acceptability, and effectiveness of a culturally tailored nutrition education intervention designed to improve diet quality and reduce nutrition-related cardiometabolic disease risk among low-income adults participating in the Los Angeles County Food Rx Fresh Produce Distribution Program. Participants are adults aged 18 years and older who experience food insecurity and receive services through Food Rx produce distribution sites.

The main questions it aims to answer are:

Does participation in the Diet Quality Matters intervention reduce food neophobia (reluctance to try unfamiliar foods)? Does participation improve overall dietary quality as measured by validated diet quality assessment tools? Does participation improve food resource management skills, nutrition-related self-efficacy, and food security? Does participation lead to improvements in cardiometabolic risk indicators, including body mass index (BMI) and blood pressure? Is the intervention acceptable, feasible, and culturally relevant to participants and program staff?

Participants will:

Complete baseline surveys assessing food neophobia, diet quality, food security, food resource management skills, and self-efficacy.

Attend three monthly nutrition education sessions that include:

Guided group motivational interviewing discussions. Live culturally tailored cooking demonstrations. Taste-testing of featured foods. Group discussions about adapting recipes to participants' cultural and household preferences.

Undergo height, weight, and blood pressure measurements. Complete follow-up surveys approximately 3 months after the final intervention session.

Participate in optional feedback interviews regarding their experiences with the program.

Treatments tested in this trial

Diet Quality Matters (DQM) Nutrition Education and Culinary Skills Program
Behavioral
Diet Quality Matters (DQM) is a culturally tailored behavioral nutrition education intervention designed to improve diet quality and reduce cardiometabolic disease risk among food-insecure adults participating in the Los Angeles County Food Rx Program. Adapted from the evidence-based Cooking Matters curriculum, DQM combines motivational interviewing, nutrition education, cooking demonstrations, taste testing, and culturally relevant group discussions to increase consumption of diverse minimally processed plant foods and reduce food neophobia. Participants attend three monthly in-person group sessions, each lasting approximately 60 minutes and delivered during Food Rx produce distribution events. Sessions include guided motivational interviewing (15 minutes), a live recipe demonstration and taste testing (30 minutes), and a discussion on adapting healthy eating practices to participants' cultural and household preferences (15 minutes).

Trial outcomes

Primary outcomes

Change in Diet Quality - GDQQ GDR Score

Change in overall diet quality as measured by the Global Dietary Quality Questionnaire (GDQQ)-Global Dietary Recommendations (GDR) Score. Range 0-18 with higher score indicating better diet quality. Calculated by GDR Score = NCD-Protect Score - NCD-Limit socre + 9

Time frame

Assessed at baseline, prior to study intervention, and again 30 days post last intervention session

Change in Diet Quality - MDS

Change in overall diet quality as measured by the PREDIMED Mediterranean Diet Score. Range 0-9 with higher score indicating increased adherence to mediterranean diet.

Time frame

Assessed at baseline, prior to study intervention, and again 30 days post last intervention session

Change in NCD-Protect Score

Change in consumption of food groups associated with protection against noncommunicable diseases (NCDs) will be assessed using the NCD-Protect score derived from the Global Diet Quality Questionnaire (GDQQ). The score reflects consumption of health-promoting food groups, including fruits, vegetables, whole grains, legumes, nuts and seeds, and other recommended foods represented in the GDQQ. Higher scores indicate greater consumption of NCD-protective foods and a more favorable dietary pattern with a range 0-9

Time frame

Assessed at baseline, prior to study intervention, and again 30 days post last intervention session

Change in NCD-Limit Score

Change in consumption of food groups recommended for limitation for prevention of noncommunicable diseases (NCDs) will be assessed using the NCD-Limit score derived from the Global Diet Quality Questionnaire (GDQQ). The score reflects consumption of foods that dietary recommendations advise limiting, such as highly processed foods and foods high in added sugars, sodium, or unhealthy fats, as represented in the GDQQ. Lower scores indicate lower consumption of foods recommended for limitation and a more favorable dietary pattern with a range 0-9.

Time frame

Assessed at baseline, prior to study intervention, and again 30 days post last intervention session

Secondary outcomes

Change in Cardiometabolic Risk Indicators - BMI

Change in body mass index (BMI). Weight and height will be combined to report BMI in kg/m\^2

Time frame

Baseline, prior to study intervention, and again 30 days post last intervention session.

Change in Cardiometabolic Risk Indicators - Grip Strength

Change in grip strength (kg) using dynamometer.

Time frame

Baseline, prior to study intervention, and again 30 days post last intervention session.

Change in Cardiometabolic Risk Indicators - Systolic BP

Change in systolic blood pressure (mmHg) collected using sphygmomanometer.

Time frame

Baseline, prior to study intervention, and again 30 days post last intervention session.

Change in Cardiometabolic Risk Indicators - Diastolic BP

Change in diastolic blood pressure (mmHg). Collected using sphygmomanometer.

Time frame

Baseline, prior to study intervention, and again 30 days post last intervention session.

Other outcomes

Participant-Reported Acceptability of the Diet Quality Matters Intervention

Participant-reported acceptability of the Diet Quality Matters intervention, including overall experience with the program, satisfaction with intervention activities, and perceptions of the cooking demonstrations, taste-testing, and nutrition education components. Acceptability will be assessed through participant responses to a semi-structured feedback interview. Unit of Measure: Participant-reported perceptions/themes related to intervention acceptability Measurement Tool: Diet Quality Matters Participant Feedback Survey (semi-structured interview)

Time frame

Assessed one time at the 30 day post-intervention follow-up assessment

Participant-Reported Usefulness of the Diet Quality Matters Intervention

Participant perceptions of the usefulness and perceived impact of the intervention, including whether cooking demonstrations, recipes, taste-testing, and nutrition education were helpful for supporting healthier food choices and incorporating foods distributed through the Food Rx program into meals. Unit of Measure: Participant-reported perceptions/themes related to intervention usefulness and perceived impact Measurement Tool: Diet Quality Matters Participant Feedback Survey (semi-structured interview)

Time frame

Assessed one time at the 30 day post-intervention follow-up assessment

Participant-Reported Cultural Relevance of the Intervention

Participant perceptions of the cultural relevance and appropriateness of intervention recipes, foods, taste-testing activities, and nutrition education, including how well intervention strategies could be adapted to participants' cultural food preferences and household practices. Unit of Measure: Participant-reported perceptions/themes related to cultural relevance and appropriateness Measurement Tool: Diet Quality Matters Participant Feedback Survey (semi-structured interview)

Time frame

Assessed one time at the 30 day post-intervention follow-up assessment

Participant-Reported Feasibility and Barriers to Participation

Participant perceptions of the feasibility of participating in the Diet Quality Matters intervention, including barriers and facilitators related to attending sessions, accessing and preparing recommended foods, using Food Rx produce, and incorporating intervention recommendations into daily life. Unit of Measure: Participant-reported perceptions/themes related to feasibility, barriers, and facilitators Measurement Tool: Diet Quality Matters Participant Feedback Survey (semi-structured interview)
