Protocol - Fiber Intake

Add to My Toolkit
Description:

These questions from the Five-Factor Screener may be useful to assess an individual’s approximate intake of several foods. These particular questions address fiber intake. No portion-size questions are asked. This screener does not attempt to assess total diet.

Scoring Procedures

The following procedures are used to convert an individual’s responses to an estimate of that individual’s daily intake of fiber (gm): 1. The frequency reported categorically on the questionnaire is converted to the number of times consumed per day as shown in Table 1. In general, the midpoint of the frequency range was used.

To estimate fiber (gm), the model is:

E (Dietary Factor).33 = b0 + b1NFG1P1 + b2NFG2P2 + ... + b20NFG20P20

Availability:

Publicly available

Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided. There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).

Equipment Needs

While the source instrument was developed to be administered by computer, the PhenX Working Group acknowledges these questions can be administered in a non-computerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

None

Selection Rationale

Vetted against several other dairy intake questions, these questions from the National Cancer Institute (NCI) Five-Factor Screener were selected because they are low burden and have been validated against the 24-hour dietary recall.

Research Domain Information
Measure Name:

Fiber Intake

Release Date:

October 1, 2015

Definition

A measure to estimate an individual’s daily average intake of fiber over the last 30 days as measured in grams.

Purpose

The Institutes of Medicine (IOM) set an Adequate Intake (AI) for Total Fiber in foods at 38 and 25 grams/day for young men and women respectively, based on the intake level observed to protect against coronary heart disease. Fiber decreases the absorption of fatty acids and cholesterol from the gut and may also reduce postprandial blood glucose concentrations and potentially have a beneficial effect on insulin sensitivity.
