Pregnancy and Antenatal

A 'how-to' guide for treatment and management during pregnancy and antenatal care.

Promoting healthy habits during pre-conception and antenatal stages

A woman’s preconception weight and gestational weight gain (GWG) are two of the most important and independent predictors of childhood obesity.[1] In Queensland, half of all women already live with overweight or obesity at conception.[2]

It is recommended that health professionals use GWG charts in consultation with women throughout their pregnancy. The charts should be provided to a pregnant woman during the first ante-natal visit and used to support ongoing discussion about weight at each antenatal visit.[3]

Ask and Assess

  • Pre-conception: Ask women about planning a pregnancy, and ask permission to discuss and assess preconception weight and explain its relevance.
  • Antenatal: Calculate BMI at entry to care, weigh and plot at every antenatal visit.

Advise and Assist

  • Pre-conception: Advise women of their weight range.
  • Antenatal: Advise women of recommended GWG based on their pre-pregnancy BMI. Regularly monitor and discuss pattern and rate of weight gain. Encourage self-monitoring. Provide general information on optimal nutrition, physical activity and sedentary time.

Arrange and Ask Again
