    Abstract: Changes in ovarian hormones predict changes in emotional eating across the menstrual cycle. However, in prior studies, researchers have not examined whether the nature of associations varies across dysregulated-eating severity. In the current study, we determined whether the strength or nature of hormone/dysregulated-eating associations differ on the basis of the presence of clinically diagnosed binge episodes (BEs). Participants included 28 women with BEs and 417 women without BEs who provided salivary hormone samples, ratings of emotional eating, and BE frequency for 45 days. Results revealed stronger associations between dysregulated eating and ovarian hormones in women with BEs relative to women without BEs. The nature of associations also differed, as progesterone moderated the effects of lower estradiol levels on dysregulated eating in women with BEs only. Although hormone/dysregulated-eating associations are present across the spectrum of pathology, the nature of associations may vary in ways that have implications for etiological models and treatment.

    Abstract: Recent data show shifts in genetic and environmental influences on emotional eating across the menstrual cycle, with significant shared environmental influences during pre-ovulation and primarily genetic effects during post-ovulation. Factors driving differential effects are unknown, although increased estradiol during pre-ovulation and increased progesterone during post-ovulation are thought to play a role. We indirectly investigated this possibility by examining whether overall levels of estradiol and progesterone differentially impact genetic and environmental risk for emotional eating in adult female twins ( N = 571) drawn from the Michigan State University Twin Registry. Emotional eating, estradiol levels, and progesterone levels were assessed daily and then averaged to create aggregate measures for analysis. As predicted, shared environmental influences were significantly greater in twins with high estradiol levels, whereas additive genetic effects increased substantially across low versus high progesterone groups. Results highlight significant and differential effects of ovarian hormones on etiologic risk for emotional eating in adulthood.

    Abstract: Ovarian hormones significantly influence dysregulated eating in females. However, most women do not develop appreciable disordered eating, which suggests that ovarian hormones may not affect all women equally. We examined whether individual differences in trait negative affect (NA) moderate ovarian hormone–dysregulated eating associations in 446 women who provided saliva samples for hormone measurements and ratings of NA and emotional eating daily for 45 consecutive days. Women were at greatest risk for emotional eating when they had high trait NA and experienced a hormonal milieu characterized by low estradiol or high progesterone. Although effects were evident in all women, the combination of high trait NA and high progesterone was particularly risky for women with a history of clinically significant binge-eating episodes. These findings provide initial evidence that affective and hormonal risk interact to promote emotional eating and that effects may be amplified in women with clinically significant binge eating.

    Abstract: Eating disorders are a significant source of psychiatric morbidity in young women and demonstrate high comorbidity with mood, anxiety, and substance use disorders. Thus, clinicians may encounter eating disorders in the context of treating other conditions. This review summarizes the efficacy of current and emerging treatments for anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Treatment trials were identified using electronic and manual searches and by reviewing abstracts from conference proceedings. Family based therapy has demonstrated superiority for adolescents with AN but no treatment has established superiority for adults. For BN, both 60 mg fluoxetine and cognitive behavioral therapy (CBT) have well-established efficacy. For BED, selective serotonin reuptake inhibitors, CBT, and interpersonal psychotherapy have demonstrated efficacy. Emerging directions for AN include investigation of the antipsychotic olanzapine and several novel psychosocial treatments. Future directions for BN and BED include increasing CBT disseminability, targeting affect regulation, and individualized stepped-care approaches.

    Abstract: A classical twin study was used to estimate the magnitude of genetic and environmental influences on four measurements of within-person variability, namely dominance flux, warmth flux, spin, and pulse. Flux refers to the variability of an individual’s interpersonal dominance and warmth. Spin measures changes in the tone of interpersonal styles, and pulse measures changes in the intensity of interpersonal styles. Daily reports of interpersonal styles were collected from 494 same-sex female twins (142 monozygotic pairs and 105 dizygotic pairs) over 45 days. For dominance flux, warmth flux, and spin, genetic effects accounted for a larger proportion of variance (37%, 24%, and 30%, respectively) than shared environmental effects (14%, 13%, and 0%, respectively), with the remaining variance due to the nonshared environment (62%, 50%, and 70%, respectively). Pulse appeared to be primarily influenced by the nonshared environment, although conclusions about the contribution of familial influences were difficult to draw from this study.

    Abstract: Personality traits are known to be associated with a host of important life outcomes, including interpersonal dysfunction. The interpersonal circumplex offers a comprehensive system for articulating the kinds of interpersonal problems associated with personality traits. In the current study, traits as measured by the Multidimensional Personality Questionnaire in a sample of 124 young women were correlated with interpersonal dysfunction as measured by the Inventory of Interpersonal Problems–Circumplex. Results suggest that Multidimensional Personality Questionnaire traits vary in their associations with interpersonal distress and in their coverage of specific kinds of interpersonal difficulties among women undergoing the transition to adulthood.
