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., pencil-and-paper and computer-assisted interviews).

Equipment Needs

While the source instrument was administered over the telephone, 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/handheld computer to administer a computer-assisted questionnaire.

Requirements

Selection Rationale

This question captures whether or not a child was breast-fed, the duration of breast-feeding, the age when first fed formula (if breast-fed) and age at introduction of first food (all respondents).

History of Being Breast Fed

Release Date

Definition

Question about whether or not the respondent was breast-fed as a child.

Purpose

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.
