Clinical Trial Summary

The study is a single site parallel randomized controlled study. The study will be assessing the effect of a 10% pre-conceptional weight loss intervention vs a control group among healthy couples where the prospective mother is pregnant and overweight or obese (BMI 27-44.9 kg/m^2). The couples in intervention group will receive dietitian counseling and participate in physical activity sessions to attain the 10% weight loss. The overall objective is to test whether a comprehensive pre-conceptional parental weight loss intervention effectively reduces the risk of offspring overweight, and adiposity and its complications compared to a control group.


Description:

The study is a single site parallel randomized controlled study. The study will be assessing the effect of a pre-conceptional weight loss intervention vs a control group among healthy couples where the prospective mother is pregnant (recruited at gestational age 18-36), overweight or obese (BMI 27-44.9 kg/m^2), between 18-38 years and planning an additional pregnancy within the following 3 years. The investigators will recruit a total of 140 healthy pregnant couples who will be randomized 1:1 to either intervention or control, stratified according to maternal pre-pregnancy BMI and previous or present diagnosis of gestational diabetes. The couples in intervention group will receive dietary counseling by a dietitian from 3 months post-partum of the 1st child until birth of the 2nd child. The goal is to achieve a healthy lifestyle and a moderate weight loss of 10% according to pre-pregnancy weight during the first year. Hereafter, the couples will be guided in weight maintenance until pregnancy of the second child. During pregnancy the goal is to achieve a healthy weight gain. Couples in intervention group will also participate in physical activity sessions every 2nd week and advised to walk with moderate intensity at least 2-4 times a week for at least half an hour. The overall objective is to test whether a comprehensive pre-conceptional parental weight loss intervention effectively reduces the risk of offspring overweight, and adiposity and its complications compared to a control group. The 1st baby born before intervention is started will be the "index child" and the metabolic and anthropometric parameters of the 1st child will be compared to parameters of the second child to assess the effect of the parent's healthy lifestyle between the two pregnancies. The investigators hypothesize that parental weight loss intervention, initiated before conception, will facilitate lower parental insulin resistance, inflammation, body weight and adiposity, incretin responses and energy expenditure compared to usual care. For the offspring the investigators hypothesize that the intervention will reduce adverse pregnancy outcomes with a short-term reduction in the risk of being born large for gestational age with excessive fat mass and a long-term reduction in the risk of developing overweight or obesity as a consequence of both social (family approach) and biological (epigenetic modifications) pathways.

Study Design


Intervention

Behavioral:
Weight loss intervention
Subjects will receive dietary counseling by a dietitian from 3 months post-partum of the 1st child until birth of the 2nd child. The mother (and father if overweight, BMI =25 kg/m^2) will receive advice to provide a moderate caloric restriction (-500 to 1000 kcal/d) and power walk 2-4 times a week for a half an hour and attend physical activity sessions every 2nd week to attain a minimum weight loss of approximately 0,5-1,0 kg/week. The weight loss will last until a 10% weight loss (according to pre-pregnancy weight) has been achieved or until 1-year post-partum. If the subject has not achieved a weight loss of 10%, she or he will receive Very low-calorie diet (VLCD) until target weight loss is reached, though no longer than 8 weeks. After weight loss subjects will receive counseling to maintain weight loss and healthy weight gain during pregnancy until birth of the 2nd child.

Primary Neonatal fat mass Offspring's neonatal fat mass (grams) assessed by air displacement plethysmography (Pea POD) Collected within the first week of birth (strived <48 hours)
Primary Difference in epigenetic changes in child 1 and 2 Cord blood from offspring will be collected at birth and stored at -80 °C until use. At the Department of Molecular Medicine AUH genomic DNA will be extracted from peripheral blood using standard methods e.g., QIAmp® Mini Kit (Qiagen, Germany). 1 µg of genomic DNA will be bisulfide converted using Illumina iScan (platform). The methylation level will be measured using Infinium MethylationEPIC DNA Analysis BeadChip (Array type) at Eurofins Genomics AS (Denmark) or similar methods.
The stated required sample size (140 couples) is calculated based on the neonatal fat mass. As no other studies have performed methylation analysis using WGBS in similar cohorts, precise power calculations on epigenetic changes are impractical. However, since the EPICOM study found differentially methylated regions in only 20 cases and 20 controls using Illumina's 450K methylation assay, the power to elucidate epigenetic changes is considered sufficient in the planned study.
