The association between attachment avoidance and quality of life in bariatric surgery candidates.

Objective: Patients presenting for bariatric surgery have high rates of psychiatric co-morbidity and reduced health-related quality of life (HRQOL) compared to the general population. In this study, we aimed to determine the relationship between insecure attachment styles and HRQOL in bariatric surgery candidates.

Methods: We assessed depression, social support, attachment avoidance, attachment anxiety, HRQOL (SF-36), and eating disorder psychopathology in 70 consecutive patients assessed for bariatric surgery.

Is human seasonality implicated in the risk profile for obesity?

Although seasonality might once have been a successful energy conservation strategy for people living in temperate regions, this physiological phenomenon may now foster accumulating annual weight gain and thereby feature in the risk profile for obesity. We tested the hypothesis that seasonality relates to BMI, and that this association is mediated by a preference for carbohydrates and the tendency to binge eat. In a sample of men and women, gender significantly moderated the relationship between seasonality and BMI.

Education level moderates learning on two versions of the Iowa Gambling Task.

The Iowa Gambling Task (IGT) is the major plank of behavioral support for the Somatic Marker Hypothesis--a prominent theory of emotionally-based decision making. Despite its widespread use, some have questioned the ecological and discriminative validity of the IGT because a substantial proportion of neurologically-normal adults display a response pattern indistinguishable from those with ventromedial prefrontal cortical brain lesions. In a large sample of healthy adults, we examined the statistical influence of several demographic variables on two versions of the IGT, with the specific prediction that educational attainment would moderate learning across trials.

Symptoms of attention-deficit/hyperactivity disorder, overeating, and body mass index in men.

Background: The high prevalence of obesity currently poses a global health crisis. Previous research has identified a novel link between obesity and Attention-Deficit/Hyperactivity Disorder (AD(H)D). Davis, Levitan, Smith, Tweed and Curtis [Davis, C.
