Pregnant women’s knowledge of obesity and ideal weight gain in pregnancy, and health behaviours of pregnant women and their partners.

We conducted a survey among a convenience sample of 149 women and their partners (n = 136) attending antenatal services in the Canberra Hospital in 2010. Over one-third (39%) of women and 63.6% of their partners were overweight/obese, and 69.2% of women had not received advice from their caregiver on their weight. Pregnant women and their partners’ health behaviours including smoking, and fruit and vegetable intake were strongly correlated (P ≤ 0.01). Pregnant women require targeted advice on their weight, ideal weight gain and impact of these on pregnancy.
