Scientific title | Hypnotherapy for adherence to nutritional and physical activity recommendations during pregnancy in obese pregnant women: feasibility of an intervention, a randomised controlled trial |
Study objectives | Obesity exposes mother and foetus to higher risks of perinatal complications. Institute of Medicine (IOM) recently suggested that obese women gain between 5 and 9 kg during pregnancy. Almost 30% of pregnant women are overweight and 60% of them had a gestational weight gain (GWG) that did not meet IOMs recommendations. Weight gain during pregnancy over the recommended values exposes the mother and her infant to higher risks for perinatal adverse outcomes independently of the body mass index (BMI), such as diabetes or large for gestational age infants. Lifestyle interventions might improve nutritional habits and the practice of physical activity during pregnancy. Psychological interventions have to be targeted to elicit effective responses to intervention programs. Cerebral structures act as a network to influence feeding behaviour and appetite control. A hypnotherapy intervention was thus developed to enhance motivation and adherence to healthy lifestyle habits (i.e. healthy nutrition and physical activity) during pregnancy in obese pregnant women. Hypnotherapy is a promising tool for inducing changes in attitudes and perceptions in the management of eating disorders. By increasing self-esteem, self-efficacy and resilience, it may assist pregnant obese women with integrating healthy behaviours in a meaningful way in order to achieve successful perinatal outcomes. We hypothesised that a standardised hypnotherapy intervention for obese women during pregnancy will enhance motivation and adherence to nutritional and physical recommendations. |
Ethics approval(s) | Ethics Committee of the Clinical Research, University Hospital Centre of Quebec ((Comite d'ethique de la recherche clinique du Centre Hospitalier Universitaire de Quebec) approved on 22nd April 2009, reference number:129.05.07(5-09-03-04) |
Health condition(s) or problem(s) studied | Gestational obesity |
Intervention | If the woman is randomised in the hypnosis group, she will receive four sessions of hypnotherapy (weeks 16, 18, 20 and 24). She is also given the option to attend two additional hypnotherapy sessions at weeks 27 and 32. Each session is delivered individually, lasting between 30 to 40 min in duration and is provided by one experienced hypnotherapist who reliably mastered all key elements of the intervention after training and observation. The intervention protocol is standardised in a manual for all six sessions. A written script is read to the participants. If the woman is randomised in the control group, she does not receive any hypnotherapy session. |
