Protocol - History of Being Breast-Fed - Adult
The respondent is asked whether or not his or her mother breast-fed him or her.
1. Did your mother breast-feed you?
1 [ ] Yes
2 [ ] No
8 [ ] Don’t know
Protocol Name from Source:
Long Island Breast Cancer Study
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.*
* There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).
While the source instrument was administered in-person via a paper-and-pencil instrument, the PhenX Working Group acknowledges that these questions can be administered in a computerized format (i.e., computer-assisted personal interview). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer or handheld computer to administer a computer-assisted questionnaire.
|Specialized requirements for biospecimen collection||No|
|Average time of greater than 15 minutes in an unaffected individual||No|
Mode of Administration
Ideally, a question about the duration of breast-feeding also would be added to this protocol. Men may be less likely than women to know whether they had been breast-fed as an infant.
If the subject is a child and the respondent is the child’s adult parent or guardian, consider the more detailed Child Protocol.
This is a simple question that captures the basic information needed about whether or not the person was breast-fed.

History of Being Breast Fed
May 31, 2016
Question about whether or not the respondent was breast-fed as a child.
Human milk has health benefits for infants (i.e., nutritional and immunologic benefits). Lactation has been shown to be beneficial to the health of mothers (e.g., lower risk of some cancers). Breast-feeding also has been shown to have psychological and neurodevelopmental benefits. Unfortunately, human milk may also be a vehicle for transfer of viruses (e.g., HIV) and environmental chemicals (e.g., polyhalogenated chemicals). Generally, the benefits of human milk and lactation have been found to outweigh the risks of exposures to pathogens or toxic substances in breast milk but there are higher-risk situations that have been recognized. Researchers can use information about breast-feeding to make inferences relevant to early nutritional status and immunologic development, the mother-child relationship, and potential exposures.
