Polycystic ovary syndrome (PCOS) affects ⩽10% of women of reproductive age in the UK and obesity is a common feature of this syndrome. Food craving, emotional eating and uncontrolled eating have all been anecdotally reported by women with PCOS(Reference Herriot, Whitcroft and Jeanes1,Reference Bailey2). The present study aims to describe the eating behaviours and snacking habits in women with PCOS and investigate their relationship with BMI.

Twenty-four women (aged 31.5 (sd 6.9) years) completed a 3 d food diary and the three-factor eating questionnaire (TFEQ-R18)(Reference Stunkard and Messick3); these data were analysed to provide eating frequency and emotional eating score, uncontrolled eating score and cognitive restraint score respectively. Eating episodes were calculated by splitting foods into subcategories of drinks, mixed meals and savoury or sweet snacks. Snacks were classified as foods consumed between meals. Weight and height were measured and BMI calculated. BMI was split into categories of <25 kg/m2, 25–29.9 k/gm2 and >30 kg/m2.

The mean BMI of women with PCOS was 29.1 (sd 5.6) kg/m2; there were six of normal weight, eleven were overweight and seven were obese. Eighteen (75%) had a waist circumference ≥88 cm, denoting a substantially increased risk to health(4). The mean score for emotional eating was 59 (sd 32), uncontrolled eating score 43(sd 24) and cognitive restraint score 39 (sd 21).

Emotional eating score and BMI were positively related (r 0.53, P=0.01) as was uncontrolled eating score and BMI(r 0.47, P=0.04). These findings are similar to previous findings reported in healthy women(Reference van Strein, Frijter and Roosen5). There was a trend towards a significantly greater emotional eating score in overweight and obese women compared with lean women (27 (sd 12) v. 33 (sd 8) respectively; P=0.08). Additionally, there was a trend towards a relationship between number of eating episodes (excluding drinks) and uncontrolled eating score (r 0.42, P=0.06). There was no correlation between eating frequency and BMI, which is in agreement with the findings of a study in healthy adults(Reference Hampl, Heaton and Taylor6).

The present study is the first to report the eating behaviours in women with PCOS and relate them to BMI. Although the study population is small, it is imperative to identify the incidence and severity of disordered eating in this population to allow dietary information for this population to be more effectively tailored to help maximize the success of lifestyle interventions.
