NutriPlant - Opportunities for Increasing Consumption of Local Fruits and Vegetables (NutriPlant)

January 14, 2025 updated by: Nutrition Institute, Slovenia

Opportunities for Increasing Consumption of Local Fruits and Vegetables in Slovenian Population (NutriPlant)

The effects of different foods to normal bowel function in adult population will be investigated. A randomised controlled intervention trial will be conducted on about 120 (30 per group) adult (18-70 years) subjects with functional constipation and irritable bowel syndrome with constipation according to the IV. Rome criteria. At least one week before inclusion in the study, patients will stop taking laxatives and other anti-constipation medications. Subjects will be randomly selected to consume one of the test foods (fresh apples, dried apples, sauerkraut) or the active control (psyllium) in the equivalent amount of 3 g of fiber per day for 4 weeks. Subjects will be asked not to change their lifestyle habits, such as diet and physical activity level, and not to take oral laxatives during the period of participation in the study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

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.
120

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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 frequency of complete spontaneous bowel movements (CSBM) / week
Time Frame: fourth week vs pre-intervention
Daily measurement of number of complete spontaneous bowel movements
fourth week vs pre-intervention

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 constipation symptom score (CSC)
Time Frame: fourth week vs pre-intervention
Measurement with constipation symptom score (0-48 points, higher SCS score mean more severe symptoms)
