gain in pregnancy through the provision of information on healthy eating and opportunities to be physically active. The aim of this evaluation was to provide preliminary evidence on efficacy. Methods: Participants’ were assessed at the beginning and end of the course, in terms of healthy eating and physical activity (PA) behaviour, mental well-being, and mediating variables (i.e. intentions, self-efficacy and attitudes towards healthy eating and PA). Results: Thirty-four out of 60 women (57%) women completed the course. There were few differences between those women who completed and did not complete the course. After attending the service, the intention-to-treat analysis showed an improvement in healthy eating (higher intake of fruit and vegetables, lower intake of fast food), no change in PA, reduction in sedentary behaviour and an improvement in mental well-being. Participants also increased their attitude, intention and self-efficacy towards engaging in PA and intention to eat fruit and vegetables. Conclusions: These findings suggest that women who completed the Just4Mums service improved their health behaviours. More research is needed to identify why so many women dropped out of the service. doi:10.1016/j.preghy.2014.03.023
Variation in outcomes in trials reporting effects of diet and lifestyle based intervention on pregnancy outcomes: a systematic review E. Rogozinska, Y. Fen, E. Molyneaux, K.S. Khan, S. Thangaratinam (Women’s Health Research Unit, Barts & The London School of Medicine & Dentistry, United Kingdom) Obesity is a growing threat to women of childbearing age. Increased maternal weight or excessive weight gain in pregnancy is associated with adverse pregnancy outcomes. Interventions based on diet and physical activity minimise gestational weight gain with varied effect on a number of clinical outcomes. There is no consensus amongst the trialists on the core outcomes that need to be reported to inform the clinical care of pregnant women. The aim of this systematic review is to evaluate variation in the type and quality of outcomes reported in systematic reviews and randomised controlled trials on diet and lifestyle interventions on maternal and fetal outcomes. We will assess the correlation between the type of outcome, the quality of the studies and journal impact factor. We searched the major databases from the inception to October 2013 without language restrictions. We used current recommendations for quality of outcome reporting using a 6-point scale. The quality assessment of systematic reviews and RCTs was performed using the AMSTAR and Jadad scoring systems. Additionally we obtained journals’ impact factor in the year of publication. We calculated Spearman rank coefficient to assess the correlation between the type of outcome, and study quality. An overview of outcome reporting will show the current attitude of the researchers towards outcomes of importance when conducting trials on diet and lifestyle management in

Who are we missing? Examining non-participants in ‘‘Fit for Delivery’’, a randomized, controlled trial of a lifestyle intervention in pregnancy Linda Reme Sagedal (Department of Obstetrics & Gynaecology, Sørlandet Hospital, Norway) Background: Fit for Delivery (FFD) is a randomized, controlled trial of a lifestyle intervention designed to limit weight gain and increase physical activity in pregnancy. A questionnaire for non-participants was included in the design of the study. Methods: Nulliparous women residing in southern Norway were invited to participate in FFD if they had a singleton pregnancy at 620 weeks gestation, age P18 years and body mass index (BMI) of P19 kg/m2. Women who declined participation were asked to complete an anonymous questionnaire with 7 questions. They were asked reason for nonparticipation (8 choices), age, height, pre-pregnancy weight, smoking status, educational level and frequency of physical activity. Study participants (n = 606) completed a more comprehensive questionnaire before randomization. Responses were compared using independent-samples t-test and chisquare test for continuous and categorical data, respectively. Results: Non-participants who completed the nonresponse questionnaire (n = 60) most often cited satisfaction with their own nutrition and fitness plan (50%) and being too busy to exercise several days a week (43%). Compared with participants, non-participants were younger (mean difference 1.48 years, CI 0.51-2.65 (p = 0.013)), more often smokers (12.5% vs. 4%, p = 0.014), and fewer had P4 years of higher education (9.4% vs. 35.6%, p < 0.001). There were no significant differences between groups in weight, height, BMI or physical activity level. Conclusion: There is a statistically significant difference in age, smoking and educational status between FFD participants and non-participants. BMI and activity level do not differ between groups. These finding may help us in developing future interventions and trials. doi:10.1016/j.preghy.2014.03.025
Pregnancy and beyond – the role of BMI in predicting body satisfaction, eating behaviour and infant feeding across two countries Netalie Shloim (University of Leeds, United Kingdom) Introduction: Weight change during pregnancy and maternal body mass index (BMI) are associated with negative body image and restrained eating. However, there are cross-cultural differences in how these changes are experienced and how this might in turn affect maternal eating or infant feeding. The present study aimed to: (1) examine if self-esteem, eating behaviours and body satisfaction measured during pregnancy changed following birth and varied according to country (Israel vs. UK); and
