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.

Study Type

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
76

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.

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.

Arms and Interventions

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
Intervention group consisting of culturally-tailored healthy eating advice through daily text messages for 2 months (delivery phase). A reinforcement phase of 2-months will follow to repeat the text messages.
Behavioral: Culturally tailored healthy eating advice
Culturally-tailored education includes strategies for healthy eating, preferences for traditional healthy foods, recommendations for limiting unhealthy traditional foods, portion sizes, etc.
Active Comparator: Control
Control group consisting of general healthy eating advice through daily text messages for 2 months (delivery phase). A reinforcement phase of 2-months will follow to repeat the text messages.
Behavioral: Standard healthy eating advice
Standard healthy eating education includes strategies, foods, portions, and cooking and eating tips for general dietary recommendations

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in diet quality score
Time Frame: 4 months
Determine the change in score of short diet quality screener (range 18-54; from lowest to highest quality)
4 months
Changes in diet habits
Time Frame: 4 months
Determine the change in the frequency of dietary behaviors (percent)
4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in diet satisfaction: diet satisfaction scale
Time Frame: 4 months
Determine the change in the score of the Diet Satisfaction Questionnaire (DSat-45) (range 45-225; from lowest to highest satisfaction) and its summed seven subscales (ranges 5-40
4 months
Changes in attitude for eating: attitudes scale
Time Frame: 4 months
Determine the change in the score of the attitudes scale (range 0-20; with positive and negative subscales for more attitudes towards healthy eating)
4 months
Changes in reasons for eating: reasons scale
Time Frame: 4 months
Determine the change in the score of the reasons scale (range 0-15; fewer to more reasons to eat healthy)
4 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in levels of adipose risk factor
Time Frame: 4 months
Estimate the change in the value of waist circumference (cm)
4 months
Change in levels of blood pressure risk factors
Time Frame: 4 months
Estimate the change in the value of systolic and diastolic blood pressure (mmHg)
4 months
Changes in depression score: CESD
Time Frame: 4 months

4 months
Changes in dysfunctional eating behaviors
Time Frame: 4 months
Determine the change in score of the Three-Factor Eating Questionnaire (range 0-4; from lowest to highest dysfunctional eating and the three subscales of emotional, uncontrolled and restrictive eating behaviors)
