The aim of the present study is to evaluate the impact of a multidisciplinary treatment of obesity prior to IVF on global reproductive outcomes and maternofetal metabolic and cardiovascular risk factors.
This is a randomized controlled trial in obese infertile women before starting an IVF cycle. The intervention is based on a structured multidisciplinary program in support groups, which includes diet, physical activity and psychological therapy. IVF will be started immediately after this therapy. Patients included in the control group will start an IVF cycle immediately after the randomization. The results of this study may allow the identification of patients who would benefit from obesity treatment, so as to establish appropriate preventive and therapeutic strategies and to reduce the maternal obesity impact in future generations.
The aim of the present study is to evaluate the impact of a multidisciplinary treatment of obesity prior to IVF on global reproductive outcomes and maternofetal metabolic and cardiovascular risk factors.
This is a randomized controlled trial in obese infertile women (body mass index ≥30 kg/m2) before starting an IVF cycle. In the intervention group, the aim is a weight loss of at least 10% in a 16-week period of treatment based on a multidisciplinary approach and support groups, which includes diet, physical activity and psychological therapy. IVF will be started immediately after this period. Patients included in the control group will start an IVF cycle immediately after the randomization. The results of this study may allow the identification of patients who would benefit from obesity treatment, so as to establish appropriate preventive and therapeutic strategies and to reduce the maternal obesity impact in future generations.
