Measuring Nutrition Literacy in Clinical Practice: Evaluating Effects Upon Providers and Patients

March 19, 2020 updated by: University of Kansas Medical Center

The Effects of Nutrition Literacy Assessment on Patient-Centered Nutrition Education Provided by Dietitians

This study evaluates the effects of assessing patient nutrition literacy prior to an initial session with an outpatient dietitian on the patient-centeredness of the session. We will randomize 6 dietitians, 4 of whom will have access to their participating patients' nutrition literacy scores. These dietitians will use this information to better inform their interventions, and hopefully improve their patients' nutrition literacy as a result.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Nutrition Literacy Assessment Tool (NLit): a validated, 64-question survey that assesses nutrition literacy across 6 subscales:

  • Nutrition and Health
  • Energy Sources in Food
  • Household Food Measurement
  • Food Label and Numeracy
  • Food Groups
  • Consumer Skills

Dietitians who work within 6 different outpatient clinics (1 dietitian per clinic) will be recruited to the study; each dietitian will recruit 19 patients from their clinic. All patient participants will take the NLit survey prior to an initial visit with their dietitian. Dietitians randomized to the intervention arm (n=4) will have access to their participating patients' NLit results, and tailor their intervention to the patient's nutrition literacy weaknesses. Dietitians randomized to the control group (n=2) will not have access to their participating patients' NLit scores, and will provide the same standard-of-care intervention usually provided.

All participating patients will then re-take the NLit a month after their initial session with their dietitian, and we will examine the results to see if a) nutrition literacy improved within groups, and b) if the patients of the intervention dietitians showed more improvement in nutrition literacy than their counterparts being treated by the control dietitians.

We will also collect dietary pattern information from participating patients before their initial session with their dietitian, and again one month after their initial session with their dietitian. We will examine the results to see if a) dietary patterns improve with increased nutrition literacy, and b) if the dietary patterns of patients in the intervention group improve more than patients in the control group.

Finally, we will collect survey information from patients pertaining to the perceived patient-centeredness of the session with their dietitian. We will also collect audio recordings of the sessions between patients and dietitians, which will be analyzed for patient-centeredness. We will also analyze readability and clearness of printed materials used by dietitians during their interventions with patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • subjects must be at least 18 years old
  • subjects must be able to read English
  • subjects must be scheduled with a participating dietitian

Exclusion Criteria:

  • subjects with cognitive disabilities or overt mental illnesses
  • subjects with vision issues severe enough to disrupt reading of the NLit.

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Intervention
Dietitians randomized to the intervention arm will have access to their participating patients' Nutrition Literacy Assessment Instrument (NLit) scores, and base their intervention on these results.
Diagnostic test: Nutrition Literacy Assessment Instrument (NLit)
The NLit is a 64-question survey broken into 6 subscales. each subscale examines a different aspect of nutrition literacy (Nutrition and Health, Energy Sources in Food, Household Food Measurement, Food Label and Numeracy, Food Groups, and Consumer Skills). Global and subscale NLit scores will be generated for each participating patient.
NO_INTERVENTION: Control
Dietitians randomized to the control arm will not have access to their participating patients' Nutrition Literacy Assessment Instrument (NLit) scores, and will provide the standard-of-care intervention for their patients.
