Clinical Trial Summary

The main objective of this project is to assess the effects of a novel and supervised exercise intervention in overweight pregnant and their newborn.

Methods/Design: The present study is a Randomized Controlled Trial. Sixty overweight pregnant interested in participate in the intervention program will be randomly assigned to either exercise (3 sessions/week), or to usual care (control) group (30 pregnant per group). The primary outcome measures are maternal weight gain, and maternal and neonatal glycaemic profile. Secondary outcomes measure are: i) body composition; ii) dietary patterns; iii) physical fitness; iv) objectively measured physical activity and sedentary behaviour; v) sleep quality; vi) mental health, quality of life and positive health; vii) haematology and biochemical analysis; viii) oxidative stress; ix) pro- and anti-inflammatory markers; x) bone health biomarkers; xi) adiposity-related proteins expression. The data will be analysed on an intention-to-treat basis and per protocol.

Intervention

Other:
Exercise intervention
The exercise intervention will be performed in two groups so that each group will have 12-13 participants.The groups will train 3 days/week (60min per session) from the 16th week of gestation until delivery. The exercise intervention group will go through different phases of training: a) Learning phase: which will involve the intervention plan, the goals we want to work, and how we will perform it; b) Movement Learning phase: theoretical and practical sessions with the explanation of movements and ergonomic basic patterns; and c) Physical Fitness Training phase: with training sessions aimed at improving fitness and weight loss, and training sessions focused on a correct pelvic mobilization for the delivery.The intensity will be adapted during the exercise program based on the week of gestation and each pregnant heart rate. The sessions will consist of a mixed work, composed of circuits where both muscular and cardiovascular conditioning will be implemented.

Outcome

Type Measure Description Time frame Safety issue
Primary Insulin sensitivity derived from the homeostatic model assessment for insulin resistance (HOMA-IR) Insulin sensitivity will be derived from the homeostatic model assessment for insulin resistance (HOMA-IR), which will be calculated using the formula [fasting insulin (µIU/mL) x fasting glucose (mg/dL)]/405. 34th week of gestation
Primary Maternal weight gain (kg) Maternal weight gain will be defined as the weight change from baseline measurement to the last measurement 34th week of gestation
Primary Neonatal insuline-glucose index Neonatal insulin sensitivity will be assessed through the ratio glucose/insulin. At delivery in cord blood samples
Secondary Systolic and diastolic blood pressure (mmHg) Systolic and diastolic blood pressure (mmHg) will be measured after 5 minutes of rest, on 2 separate occasions (with 2 minutes between trials), with the person seated (Omron Health Care Europe B.V. Hoolddorp). The lowest value of the two trials will be selected for the analysis. at the 16th and 34th week of gestation
Secondary Resting heart rate (bpm) Resting heart rate (bpm), will be measured after 5 minutes of rest, on 2 separate occasions (with 2 minutes between trials), with the person seated (Omron Health Care Europe B.V. Hoolddorp). The lowest value of the two trials will be selected for the analysis. at the 16th and 34th week of gestation
Secondary The Mediterranean Diet Score The Mediterranean Diet Score in a version adapted to the specific needs during pregnancy for Fe, Ca and folic acid will be used to assess the adherence to the traditional Mediterranean dietary pattern. at the 16th and 34th week of gestation
Secondary Cardiorespiratory fitness (Vo2max) The modified Bruce protocol will be performed to estimate maximal oxygen uptake (VO2max), and will be used as measure of cardiorespiratory fitness. at the 16th and 34th week of gestation
Secondary Cardiorespiratory fitness (meters in the 6-min walk test) We perform the 6-minute walk test, which measures the maximum distance (in meters) each participant can walk in 6 minutes along a 45.7 m rectangular course. at the 16th and 34th week of gestation
Secondary Muscle strength (kg) The handgrip strength test will be used as measure of strength at the 16th and 34th week of gestation
Secondary Flexibility (cm) The back-scratch test will be used as measure of flexibility at the 16th and 34th week of gestation
Secondary Physical activity and sedentary behaviour (in minutes) Accelerometry will be used to objectively assess physical activity and sedentary time. Women will be asked to wear a tri-axial accelerometer (ActiSleep+, Pensacola, Florida, United States) for 9 consecutive days, starting the same day they receive the monitor (e.g. participants who receive the accelerometer on Monday, will carry the device until Tuesday of the next week). Participants will be instructed to wear the accelerometer during the whole day (24 hours) on their wrist attached by an elastic belt. Time (in minutes) engaged in light, moderate, and moderate-vigorous intensity PA and sedentary time will be calculated. This accelerometer has been previously used in pregnancy with similar methodology as described in the present protocol. at the 16th, 24th and 34th week of gestation
Secondary Sleep behaviours (through accelerometry) Behaviours related to sleep, such as sleep onset, sleep latency, total sleep time, number and duration of awakenings and sleep efficiency will be objectively calculated by using a triaxial accelerometer (ActiSleep+, Pensacola, Florida, United States).

Secondary Adiposity-related proteins expression (in mother and cord blood) Glucocorticoid receptor; peroxisome proliferation activated receptor (PPAR); the beta-11 hydroxysteroid dehydrogenase type I (11ßHSD1), and beta-11 hydroxysteroid dehydrogenase type II (11ßHSD2) will be assessed in maternal and umbilical cord blood and in oral mucosa from the mother and newborn.
Moreover, 4 genes highly involved in foetal and postnatal development of adipose tissue have been selected; two are receptors: the Glucocorticoid receptor and the PPAR-?, and two are metabolic enzymes: beta-11 hydroxysteroid dehydrogenase type I or 11ßHSD1, and 11 beta-hydroxysteroid dehydrogenase type II or 11ßHSD2. Of great importance are PPAR-?1 and PPAR-?2, which are generated from the same gene by alternative promoter usage and mRNA. We will measure such proteins as well as paraoxonase/arylesterase 1 (PON1) concentrations in maternal and umbilical cord plasma by Polymerase Chain Reaction and Western Blot techniques.
