Increase in MedDiet Adherence in Pregnancy

May 17, 2023 updated by: Andriana C Kaliora, Harokopio University

Application of Clinical Decision Support System to Assist Pregnant Women to Increase Mediterranean Diet Adherence : A Randomised Controlled Trial

In the present randomised-controlled 3-month dietary intervention, we aim to a) increase Mediterranean diet adherence among apparently healthy pregnant women with the support of CDSS, and b) assess nutritional status and psychological parameters (anxiety and depression). To our knowledge, this is the first attempt investigating the effectiveness of CDSS in Mediterranean diet adherence of pregnant women.

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

In this two-armed, single center, randomised controlled 3-month trial, apparently healthy pregnant women are randomly assigned to either the Control or the Intervention arm. The appointed statistician applies simple randomisation through a computer-generated randomization sequence. Treatment allocation is exposed to the statistician only after the assessment of outcomes.

At baseline before the start of the trial, each enrolled participant is appointed to a well-experienced dietician. In the Intervention group (CDSS group), women receive a personalised daily dietary plan based on the Mediterranean diet and according to participant's needs, habits and preferences. All elements needed for the synthesis of the dietary plan i.e., gestational age, body mass index (BMI) before the fetus conception, daily total energy expenditure, physical activity level based on the concept of metabolic equivalent of task (MET), caloric needs according to nutritional status, and macronutrient distribution are calculated using the CDSS database. The CDSS-dietary regimen consists of a daily eating program that was renewed every 15 days, paired with nutritional recommendations that are in line with the "National Dietary Guidelines for Pregnancy" [http://www.diatrofikoiodigoi.gr/?page=summary-women].

Before the start of the trial, women are trained to use the CDSS and receive individual login passwords. On a weekly basis, participants are instructed to input a 3-day food diary in the CDSS, made automatically available to the dieticians. When entering the CDSS, women monitor their personal goals i.e., body weight, physical activity, consumption of fruits and vegetables. Every other week, phone interviews are also performed to support nutritional and lifestyle consultation. Additionally, unexpected phone calls are made to obtain 24-hour dietary recalls.

Participants of the Control group do not have access to CDSS and only received general lifestyle guidelines based on the "National Dietary Guidelines for Pregnancy" via scheduled phone calls every 15 days with the appointed dietician. Women of the Control group are instructed to keep a 3-day food diary every week, sent by e-mail to the appointed dietician. Again, unexpected phone calls are made to obtain 24-hour dietary recalls.

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)

Accepts Healthy Volunteers

Yes

Description

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
Change in the Mediterranean diet adherence
Time Frame: 3 months
Differences in MedDiet adherence will be assessed by MedDiet score.
3 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
