Twenty-three pregnant women, age 35.6 years (SD 4.8; range 27.0–44.6), were recruited at 16.3 weeks gestation (SD 2.2; range 11.4–20.6) from The Women's Hospital, Melbourne, Australia. Women who had quit smoking in the previous 6 months were excluded; however those who continued to smoke were not. Maternal height and weight were measured at study entry. Overweight and obesity was defined as a body mass index (BMI)≥25 kg/m2, which we believe will not …
