Obesity-fertility Cohort Study: Protocol for the Assessment of Children Aged 6-12 Years and Their Mothers

Maternal preconception obesity and adverse gestational metabolic health increase the risk of childhood obesity in offspring. A group of investigators from Université de Sherbrooke therefore developed a lifestyle intervention starting during preconception in women with obesity and infertility, which was evaluated with the Obesity-Fertility randomized controlled trial (RCT). The present study will assess children who were born in the Obesity-Fertility RCT and are now aged 6-10 years old. The objective of this study is to evaluate the effect of a lifestyle intervention during preconception and pregnancy on adiposity and cardiometabolic parameters in offspring compared to those born to mothers who did not have access to the lifestyle intervention. The hypothesis being that, at the age of 6-10 years old, children born to mothers who were in the intervention group have more favorable measurements of body composition and certain metabolic and/or inflammatory blood markers than those born to control mothers. Participants in the Obesity-Fertility RCT were women with obesity and infertility recruited at the Centre hospitalier universitaire de Sherbrooke (CHUS) fertility clinic. They were randomly allocated to the control group, which followed standard care, or to the intervention group, which received a lifestyle intervention alone for 6 months, and then in combination with fertility treatments. Those who have given birth to a single child will be invited to participate in this follow-up study with their child. During the research visit, medical history, anthropometry, body composition, lifestyle, physical fitness level, and blood or saliva markers of cardiometabolic health will be assessed for both mothers and children. This study will provide new evidence on the impact of targeting lifestyle habits during preconception on the health of children and their mothers 6-10 years later; and the potential of such interventions to counteract the intergenerational transmission of obesity.

Healthy for my Baby- RCT of a Lifestyle Intervention for Overweight Women in Preconception

The purpose of this study is to determine whether an intervention combining motivational interviewing and follow-up with a mobile phone application will help overweight women and their partners adopt healthy lifestyle habits in the preconception period. This study will also evaluate the impact of the intervention on the weight, waist circumference, and body fat of women and their partners. Women and their partners will be followed through pregnancy to explore the effects of the intervention on the adequacy of gestational weight gain, rates of pregnancy complications, delivery mode, and infant birth weight.

Generation R Next - Optimaal Opgroeien

The aim of this randomized controlled trial is to improve birth outcomes and long-term outcomes in mother and child by optimizing lifestyle,nutrition and stress experience in the preconception period and early pregnancy in women and men The main research question that will be addressed is: Does an intervention focused on optimizing preconception and early pregnancy lifestyle, nutrition and stress improve the birth outcomes and long-term outcomes in mother and child? Participants will receive an individual lifestyle consultation at the start of the study. Depending on their study arm, participants will receive an additional lifestyle program focused on health during preconception and early pregnancy, coping with stress and adherence to a healthy(er) lifestyle. The given advices are based on national guidelines. Researchers will compare the intervention group and control group to see if (adherence to) this lifestyle program improve birth outcomes and long-term outcomes in mother and child.
