Table 4:

A summary of the needs, benefits, and clinical utility of the pre-pregnancy weight calculator.

Weight is required to compute patient BMI

In pregnancy, pre-pregnancy weight is used to define healthy weight gain projections

Some women may not have access to a scale.

Patient self-reported weight is sometimes under-estimated.

Underestimating pre-pregnancy weight can lead to less conservative BMI classification prescribing more liberal weight gain in pregnancy.

The pre-pregnancy weight calculator predicts pre-pregnancy weight, confirms the validity of patient self-report and shows if pre-pregnancy BMI is misclassified.
