Protocol - History of Being Breast-Fed - Adult
Description
The respondent is asked whether or not his or her mother breast-fed him or her.
Specific Instructions
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.
Availability
This protocol is freely available; permission not required for use.

1. Did your mother breast-feed you?
1 [ ] Yes
2 [ ] No

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).
Equipment Needs
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.
