NCT02155751

Brief Summary

This is a pilot project in which investigators will recruit obese (pre-pregnancy BMI of ≥ 35 kg/m2) women from the newly developed "My Clinic" at London Health Sciences Centre as well as normal obstetrical care at London Health Sciences Centre. Patients will be randomized to one of three treatment groups: 1) the full Nutrition and Exercise Lifestyle Intervention Program (NELIP), 2) Nutrition program only, or 3) Exercise program only. The investigators hypothesize that the evidence-based NELIP for obese pregnant women will be feasible to adopt in a clinical setting and will prevent excessive gestational weight gain, gestational diabetes and promote healthy infant growth patterns at the 6 and 12 month milestones. Outcomes may be improved in My Clinic over normal obstetrical care patients with interprofessional services.

Outcome Measures

Primary Outcomes (1)

  • Weight gain in pregnancy

    Average weekly weight gain and total weight gained throughout pregnancy; recorded from initial recruitment (12-20 weeks GA) to date of delivery (up to 42 weeks). This would include approximately 20 weeks on average of follow-up in the clinic, but up to a maximum of 30 weeks total. Women are assessed at 6 months post partum and weight change measured also.

    up to 42 weeks

Secondary Outcomes (6)

  • Infant birth weight

    Measured at time of birth

  • Neonatal morphometrics

    Measured at birth, 6 months postpartum, 12 months postpartum

  • Birth complications

    Measured at time of birth

  • Breast feeding

    Measured at birth, 6 months postpartum, 12 months postpartum

  • Maternal weight retention

    Measured at 6 and 12 months postpartum

  • +1 more secondary outcomes

Study Arms (4)

Full NELIP group

EXPERIMENTAL

These women (n=10) will receive the full NELIP intervention and will be introduced to both the dietary program and the exercise program as described above under "detailed description".

Behavioral: Nutrition Lifestyle Intervention Program (NLIP)Behavioral: Exercise Lifestyle Intervention Program (ELIP)

Exercise program only/ELIP

EXPERIMENTAL

These women (n=10) will only be given the exercise component (ELIP) of NELIP, as outlined below in interventions. Once dietary intake has been assessed, this group will not be given any dietary intervention but will be encouraged to eat a healthy, balanced diet. Access to the nutritionist in the clinic is available and encouraged.

Behavioral: Exercise Lifestyle Intervention Program (ELIP)

Nutrition program only/NLIP

EXPERIMENTAL

These women (n=10) will only be given the nutrition program (NLIP) of NELIP as outlined below in intervention. They will be encouraged to be more active but will not be given an exercise intervention.

Behavioral: Nutrition Lifestyle Intervention Program (NLIP)

Control

NO INTERVENTION

A control group (n=30) of obese pregnant women will also be recruited and will be matched by pre-pregnancy BMI, maternal age and parity, with no intervention, but will attend the clinic for standard obstetric care and follow-up.

Interventions

The dietary program will mimic the gestational diabetic meal plan: a) individualize total energy intake with a minimum of 2000 kcal/day (8360 kJ/day), taking into account the usual energy intake as indicated by each dietary assessment (including 3-day food intake records) with a restriction of not more than 33% total energy intake; b) adjust if necessary the total carbohydrate intake to 40-50% of total energy intake, distributing carbohydrate intake throughout the day with three balanced meals, and three snacks per day emphasizing complex carbohydrates and low glycemic index foods; c) adjust the total fat intake to 30% of total energy intake (substituting monounsaturated fatty acids for saturated and trans-fatty acids), with the remaining 30% dedicated to protein intake; and d) meet all micronutrient and fluid needs recommended during pregnancy.

Full NELIP groupNutrition program only/NLIP

The exercise program includes a walking program in which pregnant women walk for 25 minutes, 3 to 4 times per week, adding 2 minutes each week, until 40 minutes is reached and then maintained until delivery. Each woman will be given a pedometer and log sheet to keep track of daily steps and to initiate self-monitoring behaviour.
