[ ] NO................................................................. 2

[ ] REFUSED ..................................................... 7

SP = study participant

Protocol Name from Source:

National Health and Nutrition Examination Survey (NHANES) Reproductive Health Module

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.

Equipment Needs

The PhenX Working Group acknowledges these questions can be administered in a computerized or noncomputerized 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

Major equipment 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

Life Stage:

Adolescent, Adult, Pregnancy

Participants:

Women ages 12 years and over

Specific Instructions:

Although menarche typically occurs after age 12, the Pregnancy Working Group acknowledges this could be applicable for females following menarche.

Note that a Current Pregnancy Status - Bioassay assay is the most accurate method and should be used to confirm pregnancy, if pregnancy determination is critical to the study.

Selection Rationale

Current pregnancy status can be a critical inclusion or exclusion criterion to many research protocols. Depending on specific needs and implications, researchers may accept self-report of pregnancy or require a biological sample to test for pregnancy (urine or blood). The National Health and Nutrition Examination Survey (NHANES) question on current pregnancy status was chosen as valid source from a major national study.

Definition

This measure is used to determine if a woman is currently pregnant or not.

Purpose

A biological assay is the most accurate pregnancy test. It may be important to know whether or not a woman is pregnant prior to some tests (e.g., dual-energy X-ray absorptiometry) or to the use of pharmaceutical agents as in a clinical trial. In addition, pregnancy may influence the results of several physical and health measures such as weight, blood pressure, stress, and depression. This measure can also be used to make a determination of whether the subject can be included or excluded from a research study or whether she should be excluded.
