Evaluation of Exercise, in Addition to Diet, in Women With Gestational Diabetes

June 1, 2017 updated by: Michel Boulvain, University Hospital, Geneva
The main objective is to evaluate the effect of therapeutic exercise program on blood glucose regulation in women with gestational diabetes mellitus (GDM) who are assigned to diet-and-exercise, compared to diet only (usual treatment). The primary outcome is the need for insulin treatment in the two groups.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In women with gestational diabetes, light to moderate daily physical activity may a useful therapeutic approach to improve the control of glycaemia and decrease the need for prescription of insulin. Increased physical activity in pregnant women with gestational diabetes is expected to decrease the mother and child morbidity associated with gestational diabetes, but also to improve the general health status of the mother and the child.

The objectives of this randomized trial are:

  • To evaluate the effect of therapeutic exercise program on blood glucose regulation in women with GDM who are assigned to diet-and-exercise protocol.
  • To demonstrate the feasibility of the therapeutic exercise treatment and the possibility of using the exercise program as an optional therapeutic approach for women with GDM.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Exercise + diet

Exercise intervention:

During the first session a standardized exercise prescription will be discussed with the participant. The exercise program will be of a moderate intensity, at less than 140 heart beats/min (which corresponds to 60% of the calculated maximum heart rate (HRmax) or 50% maximum oxygen volume (VO2max) ). A session of 30 to 60 minutes/week will be organised.

  • Participants will be instructed to conduct a nonsedentary lifestyle. They will be encouraged to increase their number of steps on a daily basis and perform not more that 45 minutes of continuous exercise per day. Pedometers will be used to measure the compliance and as a positive feedback for motivation.
  • The participants will return to the exercise laboratory once per week for Actiheart data downloading, number of steps recording, exercise support and counselling, and to perform the supervised group exercise intervention.

This is in addition to the diet (see below, control group)
Behavioral: Exercise
Once per week, participants will be enrolled in supervised group exercise intervention. They will be encouraged in walking 45 minutes per day
No Intervention: Diet only
Participants will receive diet counselling according to their characteristics. The usual recommendation is to have a fractioned normocaloric diet (unless the dietician identify a grossly hypercaloric diet), with low fat and increase in fibers content.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Prescription of insulin during the follow-up
Time Frame: From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery, usually 38 to 41 weeks of gestation). It is impossible in our context to give a specific time point.
The primary outcome will include any amount (dosage) of insulin and any frequency of injection. Prescription of insulin is considered when glycaemia is above 5.3 mmol/L fasting and/or above 8.0 at 1 hour after the meal.
From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery, usually 38 to 41 weeks of gestation). It is impossible in our context to give a specific time point.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Control of glycemia
Time Frame: From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
4 times per day, participants will check their blood sugar level. The investigators will record these blood sugar levels and consider as normal if below 5.3 mmol/L fasting and below 8.0 at 1 hour after the meal. Suboptimal glycemic control will be defined as 2 or more glycemia above these target values; good control will be defined as less than 2 values above the thresholds. The variable "good glycemic control" will be coded "yes" if the above criteria (<2 abnormal values) are met, and "no" otherwise (>=2 abnormal values)
From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
Compliance with the exercise (in the exercise group only)
Time Frame: From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
Satisfactory compliance will be defined as walking at least 5000 steps/day 5 days a week and attending at 50% or more of the weekly supervised exercise program. The variable "compliance" will be coded "yes" if both the above criteria are met, and "no" otherwise
From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Timing of insulin treatment
Time Frame: From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).

To better understand the effect of the intervention on the primary outcome, prescription of insulin), the investigators will compare between groups:

Time between randomization and insulin prescription (days)
From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
Gestational age at start of insulin treatment
Time Frame: From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
the investigators will compare between groups: Gestational age at start of insulin treatment (weeks) (mean ± SD)
From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
Dosage of long-acting insulin
Time Frame: From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
Maximal dose of long-acting insulin per day (mean ± SD)
From inclusion in the study (randomization usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
Dosage of short-acting insulin
Time Frame: usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
Maximal dose of short-acting insulin per day (mean ± SD)
usually between 24 and 30 weeks of gestation) until the end of pregnancy (delivery).
