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.

While the English version of this protocol has been updated, the available translations have not and reflect a previous version. These differences may impact the compatibility between the English and Spanish/Chinese versions. It is the responsibility of the investigator to determine if the translations are sufficiently compatible with the English version for their research and subsequent analysis.

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.
