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.
| Table 1. Conversion of Frequency Response to Times per Day | |
| Frequency Response | Times per Day |
| Never | 0 |
| 1-3 times per month | 0.067 |
| 1-2 times per week | 0.214 |
| 3-4 times per week | 0.5 |
| 5-6 times per week | 0.786 |
| 1 time per day | 1 |
| 2 times per day | 2 |
| 3 times per day | 3 |
| 4 times per day | 4 |
| 5 or more times per day | 5 |
2. The age- and gender-specific portion sizes (see Table 2a and 2b) for each food are multiplied by the frequency calculated in Step 1.

To estimate fiber (gm), the model is:
E (Dietary Factor).33 = b0 + b1NFG1P1 + b2NFG2P2 + ... + b20NFG20P20
For men: Cube root of fiber (mgs) =2.015301 + 0.000558 (Daily Frequency * Gender/Age Specific Portion Size per Mention for Cooked cereals) + 0.011463 (Daily Frequency * Gender/Age Specific Portion Size per Mention for High-fiber Cereal) + ... 0.001206 (Daily Frequency * Gender/Age Specific Portion Size per Mention for Cheese)
For women: Cube root of fiber (mgs) =1.838259 + 0.000671 (Daily Frequency * Gender/Age Specific Portion Size per Mention for Cooked cereals) + 0.019873 (Daily Frequency * Gender/Age Specific Portion Size per Mention for High-fiber Cereal) + ... 0.000513 (Daily Frequency * Gender/Age Specific Portion Size per Mention for Cheese) All Bran®, Bran Buds®, Raisin Bran®, Mueslix ®, Corn Flakes®, Froot Loops®, Rice Krispies®, Frosted Flakes®, Special K®, and Product 19® are registered trademarks, Kellogg NA Co.

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.
Requirements
| Requirement Category | Required |
|---|---|
| Major equipment | No |
| Specialized training | No |
| Specialized requirements for biospecimen collection | No |
| Average time of greater than 15 minutes in an unaffected individual | No |
Mode of Administration
Interviewer-administered questionnaire
Lifestage
Adult, Senior
Participants
Ages 18 years and older
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.

Measure Name
Fiber Intake
Release Date
October 30, 2009
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.
Keywords
Nutrition and Dietary Supplements, obesity, NHIS
