Abstract

First effective mHealth nutrition and lifestyle coaching program for subfertile couples undergoing in vitro fertilization treatment: a single-blinded multicenter randomized controlled trial. Fertility and sterility, 114(5), 945-954.

Smartphone-based lifestyle coaching modifies behaviours in women with subfertility or recurrent miscarriage: a randomized controlled trial

“…In developing the programme, elements of Prochaska and Diclemente's transtheoretical model with a focus on the readiness for change, Bandura's social cognitive theory for self-efficacy and Fogg's behaviour model to include triggers to motivate and increase the ability to change were applied (Bandura, 2004;Fogg BJ, 2009;Prochaska and Velicer, 1997). The validity of the Smarter Pregnancy programme has been confirmed by previous studies and serum biomarkers, such as serum folate levels reflect the reported change in lifestyle behaviours in users (Oostingh et al, 2020;van Dijk et al, 2017b).…”

“…efficacy was not assessed in the women's partners). The effect of the intervention when partners have been included has been explored previously in a Dutch cohort (Oostingh et al, 2020;Van Dijk et al, 2016;van Dijk et al, 2017a). Although this study identified improvement in lifestyle risk scores at 24 weeks after randomisation, it was not determined whether these behaviours are sustained beyond 24 weeks.…”

“…The women's diet and lifestyle were self-reported through questionnaires, and although the questionnaires have been validated (Oostingh et al, 2020;, it was not possible to eliminate reporting biases in our sample. The randomisation rate of 60% of the recruited women was due to participants failing to register for the programme within one week of recruitment, after which the activation code given to them was invalid.…”

Polycystic Ovary Syndrome: A Brain Disorder Characterized by Eating Problems Originating during Puberty and Adolescence

“…Finally, clinicians should consider the importance of underlying chronic psychological distress and eating disorders in the etiology of PCOS during both pregnancy and puberty. However, this does not preclude clinicians from implementing dietary assessment and evidence-based behavioral interventions as part of preconception and reproductive care (e.g., www.smarterpregnancy.co.uk [139][140][141]). In particular, treatment may be warranted in the case of obesity or severe emotional problems, with cognitive-behavioral therapy, with or without a lifestyle component focused on weight loss, being most commonly recommended [142].…”

Limitations of randomization for the study of nutrition, lifestyle, and in vitro fertilization success

“…Other IVF programs have our permission to copy any of the materials we have placed there. As with the study by Oostingh et al (1), a blinded study of our approach would not be possible, and we could not consider assigning couples to a control group without access to the materials. However, it would be possible for any program recommending such materials to their patients to assess improvements in those behaviors through questionnaires.…”
