“…Sullivan et al found that female patients with a BMI > 35 kg/m 2 had a higher prevalence of depressive symptoms and anxiety in comparison with other groups. 20 Similar results were obtained in various other studies, [21][22][23] come of which involved community samples. For instance, in a sample of adults residing in the United States, Simon et al noted that obesity is associated with an increase of approximately 25% in the risk of eating disorders and anxiety.…”

Objective: Obesity is a complex condition associated with a host of medical disorders. One common assumption is that obesity is also related to psychological and emotional complications. However, some studies have shown that obesity itself does not appear to be systematically associated with psychopathological outcomes. The objective of the present study was to evaluate the impact that the various degrees of obesity have on the psychopathological profile of obese patients. Method: The study sample consisted of 217 women classified as obese (body mass index ≥ 30 kg/m 2 ) who sought medical treatment for weight loss and were consecutively invited to participate in the study. Anthropometric data were registered for all participants. Psychiatric evaluations were performed using the Beck Depression Inventory and Symptom Checklist-90. Multiple regression analysis was used in order to determine whether any of the studied variables (age, level of education, Beck Depression Inventory score and body mass index) were independently correlated with the score on the different subscales of the Symptom Checklist-90. Results: Only body mass index was found to correlate significantly with the score on the somatization subscale of the Symptom Checklist-90 (r = 0.148, p = 0.035). This correlation remained significant after multiple regression analysis (p = 0.03). No correlation was found between body mass index and the score on any of the other subscales. Conclusion: The degree of obesity did not correlate with any of the psychological profiles commonly described in the medical literature, including depression and anxiety. The correlation between obesity and somatization, although weak, might simply be related to an overlapping of symptoms. Descriptors

“…a personality trait associated with overeating and obesity, 3 predicts how the amygdala responds to appetizing food pictures [118]. Additionally, self-directedness (i.e., the ability to set and pursue meaningful goals, which is typically reported as altered in eating disorders, e.g., [158]) is negatively correlated with the amygdala response to appetizing food pictures [48]. Moreover, in healthy-weight patients, the orbitofrontal cortex and nucleus accumbens, which are both involved in feeding, modulate the amygdala response to food cues.…”

• The amygdala and hippocampus play a major role in food intake and weight regulation.• These functions are far less known to cognitive and affective scientists.• This review uniquely expands on the interactions between these two brain structures. a b s t r a c t a r t i c l e i n f o The anterior medial temporal lobes are one of the most studied parts of the brain. Classically, their two main structures -the amygdalae and the hippocampi -have been linked to key cognitive and affective functions, related in particular to learning and memory. Based on abundant evidence, we will argue for an alternative but complementary point of view: they may also play a major role in food intake and body weight regulation. First, an overview is given of early clinical evidence in this line of thought. Subsequently, empirical evidence is presented on how food intake, including in the extreme case of obesity, may relate to amygdalian and hippocampal functioning. The focus is on the amygdala's role in processing the relevance of food stimuli, cue-induced feeding, and stress-induced eating and on the hippocampus' involvement in the use of interoceptive signals of hunger and satiety, as well as memory and inhibitory processes related to food intake. Additionally, an elaboration takes place on possible reciprocal links between food intake, body weight, and amygdala and hippocampus functioning. Finally, issues that seemed particularly critical for future research in the field are discussed.

“…Personality traits have previously been associated with a number of the components of metabolic syndrome, but there has yet to be a comprehensive study of the associations between personality and the syndrome as a whole. For example, impulsive individuals tend to have larger waistlines (Sullivan et al 2007;Terracciano et al 2009), higher levels of triglycerides (Sutin et al 2010b), and are more likely to have hypertension . In contrast, conscientious individuals tend to be leaner (Chapman et al 2009;Roehling et al 2008;Terracciano et al 2009), have lower triglycerides and higher HDL cholesterol (Sutin et al 2010b), and are less likely to have hypertension (Goodwin and Friedman 2006).…”

The prevalence of metabolic syndrome has paralleled the sharp increase in obesity. Given its tremendous physical, emotional, and financial burden, it is of critical importance to identify who is most at risk and the potential points of intervention. Psychological traits, in addition to physiological and social risk factors, may contribute to metabolic syndrome. The objective of the present research is to test whether personality traits are associated with metabolic syndrome in a large community sample. Participants (N= 5,662) from Sardinia, Italy, completed a comprehensive personality questionnaire, the NEO-PI-R, and were assessed on all components of metabolic syndrome (waist circumference, triglycerides, highdensity lipoprotein cholesterol, blood pressure, and fasting glucose). Logistic regressions were used to predict metabolic syndrome from personality traits, controlling for age, sex, education, and current smoking status. Among adults over age 45 (n= 2,419), Neuroticism and low Agreeableness were associated with metabolic syndrome, whereas high Conscientiousness was protective. Individuals who scored in the top 10% on Conscientiousness were approximately 40% less likely to have metabolic syndrome (OR=0.61, 95% CI=0.41-0.92), whereas those who scored in the lowest 10% on Agreeableness were 50% more likely to have it (OR=1.53, 95% CI= 1.09-2.16). At the facet level, traits related to impulsivity and hostility were the most strongly associated with metabolic syndrome. The present research indicates that those with fewer psychological resources are more vulnerable to metabolic syndrome and suggests a psychological component to other established risk factors.
