- Depression is associated with an increased risk of developing cardiovascular disease and type 2 diabetes mellitus. Abdominal obesity is also a high risk factor for these diseases. Therefore, symptoms of depression and anxiety were examined in relation to abdominal obesity. A total of 59 middle-aged men volunteered for measurements with the Hamilton Depression Scale (HDS), the Montgomery-Asberg Depression Rating Scale (MADRS), the Beck Depression Inventory (BDI) and the Hamilton Anxiety Scale (HAS). These results were examined in relation to body mass index (BMI), waist/hip ratio (WHR) and sagittal abdominal diameter, a measurement of intra-abdominal fat mass, and metabolic variables. Men with WHR > 1.0 (n=26) in comparison with men with normal WHR (< 1.0, n=33) showed significantly higher sum scores in all the scales used. There were positive correlations between the sum scores of all the depression scales and the WHR or the sagittal abdominal diameter. BMI correlated comparatively weakly only with the HDS. The correlations with the WHR remained when the influence of BMI was eliminated, suggesting that obesity is less involved than centralization of body fat. Insulin and glucose were significantly related to the HDS. Morning cortisol levels were negatively related to the BDI and (borderline) to the MADRS, suggesting perturbations of the regulation of the hypothalamic-pituitary-adrenal axis.. We conclude that men with abdominal obesity have symptoms of depression and anxiety.

- Several brain-imaging studies have found associations between aberrant functioning in the frontal and temporal lobes and violent offending. We have previously reported decreased frontotemporal perfusion unrelated to psychosis, substance abuse, or current medication in 21 violent offenders. In the present study, we compared the regional cerebral blood flow (rCBF) in a new group of 32 violent offenders to scores on the Psychopathy Checklist-Revised (PCL-R), which rates two aspects of psychopathy: disturbed interpersonal attitudes (Factor 1) and impulsive antisocial behavior (Factor 2). A recently proposed model has split Factor 1 into a new Factor 1 (deceitful interpersonal style), a new Factor 2 (affective unresponsiveness), and a Factor 3, which approximately corresponds to the old Factor 2. The rCBF was assessed by single-photon emission computed tomography (SPECT) with technetium-99m-d,l-hexamethylpropyleneamine oxime (HMPAO) in regions of interest (ROIs) placed in accordance with fusioned magnetic resonance images (MRI) and SPECT scans. Significant negative correlations were found between interpersonal features of psychopathy (the old and especially the new Factor 1) and the frontal and temporal perfusion. The two most clearly associated ROIs were the head of the caudate nuclei and the hippocampi. These findings in a group of violent offenders living under the same conditions, which reduced the number of state-related confounders, add to the evidence indicating that aberrant frontotemporal activity may be a factor in violent behavior.
