Thesis advisor: Barbara E. Wolfe / Studies suggest that eating disorder (ED) pathology may be linked to ovulatory and unexplained infertility in women who present to reproductive treatment centers. Specifically, studies have linked hypothalamic amenorrhea, oligomenorrhea, and anovulatory cycles to disordered eating. Advances in Assisted Reproductive Technology can lead to successful conception for women with ED; however, they have a higher risk for poor maternal and fetal outcomes. This descriptive, comparative, quantitative study examined disordered eating and psychological symptoms in women with ovulatory and unexplained infertility compared with women receiving routine health care from their primary care providers. Women ages 20 to 44 were recruited. After providing verbal consent, a study packet was mailed to the study participant's home. The Eating Disorder Inventory-3-Referral Form and Herman and Polivy Restraint Scale measured disordered eating symptoms. The Speilberger Anxiety Inventory and Beck Depression Inventory-II examined psychological symptoms. Provisional DSM IV TR diagnoses were ascertained using the Eating Disorder Inventory-3-Symptom Checklist, along with other scale items. Multivariate analysis of covariance (MANCOVA) confirmed that women with ovulatory and unexplained infertility had significantly higher Desire for Thinness (p = .001) and Bulimia (p = .007) subscale scores putting them at risk for Anorexia Nervosa or Bulimia. Women receiving routine care had significantly higher Body Dissatisfaction (p = .000) subscale scores consistent with their higher weight and tendency toward overeating. Women receiving routine care also had significantly higher Restraint (p = .000) scale scores, leaving them at risk for dietary disinhibition. The groups did not differ on psychological symptoms. Women with infertility had lifetime ED diagnoses many times the national ED prevalence rate, similar to the research findings of Freizinger et al. (2010). The study results support that women with ovulatory and unexplained infertility are at risk for having an occult ED. The critical import of integrating ED assessment into infertility evaluation, reproductive and primary care was implicated. Further study to isolate biobehavioral markers to better identify women at risk for ED and improve their maternal and fetal outcomes was recommended. / Thesis (PhD) — Boston College, 2010. / Submitted to: Boston College.
