Reeves1 and Y. Jeanes1 1 School of Human and Life Sciences, Roehampton University, London, UK and 2Faculty of Health and Medical Sciences, University of Surrey, Guildford, UK e-mail: firstname.lastname@example.org Background: Polycystic ovary syndrome (PCOS) affects up to 10% of women of reproductive age in the UK. Obesity is a common feature of PCOS with approximately 33% of UK women with PCOS (wPCOS) being obese (Barr et al., 2007) compared with 20% of women in the general population (Ruston et al., 2004). This research aims to compare the diet and lifestyle of wPCOS (normal and overweight) with matched controls. Methods: A 7-day food and activity diary, and medical questionnaire were completed by 37 wPCOS and 31 age and weight matched controls. A pedometer was also provided to on the same 7 days. Anthropometric measurements (body mass index, percentage body fat, and waist-to-hip ratio), and dietary intakes were compared. Percentage body fat measurements were taken using Bodystat tetrapolar bioimpedance (BodyStat, UK). Ethical approval was obtained from Roehampton University Ethics Board and the Huntingdon Research Ethics Committee. Results: There were no signiï¬cant differences for anthropometric measurements or mean energy intake between wPCOS and controls. However, percentage energy (%E) from fat, and absolute and percentage saturated fat intakes were all signiï¬cantly higher for wPCOS compared with controls (Table 1) and further from the recommendations for health. Percentage energy intake from carbohydrate for Stratiï¬cation by BMI identiï¬ed a signiï¬cant difference in %E from carbohydrate between lean wPCOS (41 Â± 6%) and lean controls (P = 0.042) and conversely a higher %E intake from fat in lean wPCOS versus lean controls (P = 0.039). Discussion: Results indicate both qualitative and quantitative differences in the dietary intakes of wPCOS compared to age and weight matched controls. However, no signiï¬cant differences in activity levels or body composition were identiï¬ed. Analysis is ongoing and will help to further elucidate the relationship between behaviour, weight and risk factor proï¬le in women with PCOS allowing for the development of more effective management strategies. Conclusions: This is the ï¬rst study to report the habitual dietary intake of UK wPCOS compared with matched controls, and results are similar to US ï¬ndings (Wright et al., 2004). Identiï¬cation of sub-optimal dietary patterns in wPCOS in the UK will allow dietary information for this population to be more effectively tailored to help maximise the success of lifestyle interventions.
