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).
