The observer should determine whether the woman is pregnant and, if she is pregnant, request how many weeks pregnant. Pregnancy status may be sensitive information, so the participants should be asked this in a private setting. Measured weight is recommended, and self-reported weight should only be recorded as a last resort.* Please indicate how the weight was collected (i.e., measured vs. self-reported). In instances where both self-reported and measured weight are collected, collect the self-reported weight first before measuring weight. *NOTE: Self-reported weight values are considered to be less accurate. Self-reported weight is subject to error and is used when measured weight cannot be obtained.
