Protocol - Total Pregnancy Weight Gain - Self-Reported Weight Gain

Add to My Toolkit
Description

There are many research contexts in which one could collect this information, and how the information is collected will vary depending on the context.

For self-reported total weight gain during pregnancy, the participant is asked to report the total amount of weight gained during her most recent pregnancy. Other data to be collected at the same time are height, duration of the most recent pregnancy, and the date of the delivery.

Protocol

Self-reported Gestational Weight Gain

This protocol for pregnancy weight is part of a personal interview. This can also be used in a self-administered format.

For women who are currently at least 20 weeks pregnant, ask the following questions:

1. Just before you got pregnant with your current pregnancy, how much did you weigh?
_______ Pounds OR ______ Kilos

2. How much weight have you gained during this pregnancy?
_______ Pounds OR ______ Kilos

[ ] I LOST weight during my pregnancy

[ ] I don’t know

3. How many weeks pregnant are you currently?
_______ Weeks (Gestational Age)

Editor’s Note: Questions 1 and 2 are modifications of questions from the Pregnancy Risk Assessment Monitoring System (PRAMS) and question 3 is a modification to the Collaborative Perinatal Study.

For women who are not currently pregnant (but parous), ask the following questions:
1. How much did you weigh before your most recent pregnancy?
_______ Pounds OR ______ Kilos

2. How much weight did you gain during your most recent pregnancy?
_______ Pounds OR ______ Kilos

[ ] I LOST weight during my pregnancy

[ ] I don’t know

3. For your most recent pregnancy, how many weeks along were you when you delivered?
_______ Weeks (Gestational Age)

Editor’s Note: Questions 1 and 2 are modifications of questions from PRAMS and question 3 is a modification to the Collaborative Perinatal Study. The phrase "most recent" was added to these questions by the Anthropometrics Working Group. This was done to broaden the context of the question from the PRAMS and Collaborative Perinatal Study populations to a nonspecific study population.

Personnel and Training Required

For the aspects of the measures requiring chart review, the abstracter should be trained in medical terminology and records review; for measuring weights, the examiner should be trained as for Measured Weight. If measurement is conducted by computer-assisted personal interview (CAPI), an interviewer trained in CAPI administration is required; otherwise, no training is required for the paper-and-pencil interview (PAPI).

Equipment Needs

Computer (for computer-assisted personal interviews), paper and pencil (for paper-and-pencil interviews)

Selection Rationale

Weight gain in pregnancy is associated with pregnancy outcomes, and there are recommended ranges of total weight gain depending on pre-pregnancy body mass index. Women who gain weight outside these recommendations (too low or too high) are at increased risk of delivering a low and high birth weight (i.e., small and large for gestational age newborns), respectively. Risk for preeclampsia, gestational diabetes, and cesarean delivery are influenced by weight gain. Excess maternal weight gain during pregnancy, especially among women who were at a normal weight before pregnancy, has also been independently associated with risk of overweight and obesity in the offspring.
