Abstract/Summary Background: Obesity is arguably the leading reason for a high risk pregnancy. Obese pregnant women are more likely to develop gestational diabetes and hypertensive disorders of pregnancy. Exercise improves insulin sensitivity and lowers blood pressure, and so it could be a valuable therapy in helping to prevent pregnancy complications in obese pregnant women. Aim: To assess the feasibility of a highly supported, individualized exercise program in obese pregnant women. Methods: 50 obese women were recruited early in pregnancy and randomized to either a highly supported, individualized exercise intervention or usual activity. Women in the intervention arm met with a physiotherapist/exercise physiologist, and had a detailed assessment of their preferences for physical activity and potential barriers to physical activity. A personalized program was developed, targetting 1500 kCal of physical activity per week (equivalent to 30 minutes of physical activity on most days of the week). Women could choose from a menu of options including pregnancy aqua-aerobics, pregnancy fitness classes, swimming, commercial fitness programs, walking, playing with their children, dancing and many other options. Women were provided with free memberships and passes to access these options, and extensive support. Programs were reviewed at least second weekly. Physical activity was measured in both intervention and control women using the validated Physical Activity Questionnaire and accelerometers. Results: At 28 weeks, women in the intervention arm showed a mean of 1213 kCal (SD 931) exercise per week compared to 710 kCal (SD 873) for the control group (p = 0.03). However, there was no statistically significant difference in the overall physical activity of the two groups. On objective measure with the accelerometer, there was no difference in physical activity in either group at any point during pregnancy. Discussion: Despite the intensive efforts to assist women to exercise in this study, there was no objective evidence that an exercise program of this type succeeded in providing women with a “dose” of exercise. There was an interesting difference between the results of the validated pregnancy physical activity questionnaire and objective accelerometer measurements. This highly supported, individualized exercise intervention is not a feasible way of increasing exercise in obese pregnant women.
