title: Dietary intake, eating behaviors, and quality of life in women with polycystic ovary syndrome who are trying to conceive.
abstract: The Healthy Eating for Reproductive Health study was conducted among 18 (45% non-white) mostly obese (BMI 39.9 ± 6.1) women with polycystic ovary syndrome (PCOS) who were experiencing infertility and interested in losing weight. A variety of markers were measured at baseline: body mass index (BMI), diet, physical activity, eating behaviors (using an Eating Behavior Inventory, a questionnaire which assesses both positive and negative eating behaviors associated with weight status, with a higher score indicating adoption of eating behaviors which have been shown in prior weight-loss research to promote a healthy weight (EBI) and the Three-Factor Eating Questionnaire, which assesses cognitive and behavioral components of eating among overweight adults), and a quality of life (PCOS Health-Related Quality of Life (PCOSQ)) index, which assesses satisfaction around five 'domains': emotional health, presence of body hair, infertility, weight, and menstrual problems). A comparison group of overweight women without PCOS (n = 28) was used to examine differences in measured outcomes between women with and without PCOS. Participants' habitual diets were high in fat and saturated fat and low in fiber, folate, and iron and contained significantly lower amounts of carbohydrate, iron, and whole grains compared with women without PCOS who had enrolled in a behavioral weight loss programme. Participants had a low EBI (indicating that most were not adopting eating behaviors associated with achieving a healthy weight), disinhibition (indicating participants had a tendency to overeat in the presence of highly palatable foods or were susceptible to emotional cues for eating, such as stress), and hunger scores (indicating participants did not report being susceptible to hunger, prompting overeating) and moderate dietary restraint (indicating they were not consistently attempting to restrict food intake consciously). PCOSQ scores were lowest for infertility and weight domains (indicating low satisfaction with current infertility and weight status); however all domains received low scores (emotional health, body hair, and menstrual problems). Higher energy intakes (kcal/day) were associated with a lower EBI score (r = - 0.60, P = 0.02), lower dietary restraint (r =- 0.50, P = 0.04), and higher disinhibition (r = 0.63, P = 0.01). Greater energy expenditure (kcal/day) was associated with lower PCOSQ scores for body weight (r =-0.54, P = 002) and infertility (r =- 0.51, P = 0.003) domains. Results suggest that overweight women with PCOS-related infertility have poor dietary intake, particularly in terms of whole grains, fiber, and iron, and eating behaviors inconsistent with achieving a healthy body weight, as well as low scores for PCOS-related quality of life.
