Comparison of Brown Rice Based-meal or Polished Rice Based-meal or Wheat Based-meal on Functional Constipation in Young Korean Women: A Opened, Clinical Trial

This study was conducted to investigate the effects of rice based-meal on functional constipation in young Korean women.

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

Studies comparing and evaluating the effects of a rice-based diet and a wheat-based diet on bowel movements are insufficient. In summary, efficient measures are needed to help individuals consume enough dietary fiber from natural sources in daily life to improve their bowel movements, rather than to consume a fiber supplements separated or synthesized from a particular natural food. In this study, investigators compare and evaluate the effects and safety of eating rice-based diets (brown rice-based and white rice-based) and a wheat-based diet in terms of bowel health and bowel movements among young women with functional constipation.

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

19 years to 30 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Inclusion Criteria:

  • Age of 19 to 30 years females
  • Meet of Rome Ⅲ diagnostic criteria of functional constipation

Exclusion Criteria:

  • Subject with a history or evidence of clinically significant gastrointestinal, anorectal, hepatic, renal, neurological, pulmonary, endocrine, blood tumor, psychiatric, cardiovascular disease
  • Subjects who have a gastrointestinal (GI) disease (Crohn's disease, etc.) that would increase the influence with absorbance medication or a GI surgery excluding appendectomy and hernia surgery
