Protocol - Breastfeeding

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. *These questions can be administered using multiple modes (e.g., paper-and-pencil and computer-assisted interviews).

Equipment Needs

Although the source instrument was developed to be administered by computer, the PhenX Working Group acknowledges that these questions can be administered in a noncomputerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop or handheld computer to administer a computer-assisted questionnaire.

Definition

A measure to assess whether a baby was breastfed, the duration of breastfeeding, and when solid foods were introduced.

Purpose

Breastfeeding is advantageous for both mothers and their children. Breast milk is the optimal source of nutrition for infants. Its components are easy to digest, include antibodies that can protect infants from bacterial and viral infections, and contain growth factors that may prevent chronic diseases later in life. Research indicates that women who breastfeed may have lower rates of certain breast and ovarian cancers and are more likely to return to their pregravid weight faster than those who do not breastfeed.
