Sleep complaints are very common among the general population and are usually accompanied by significant medical, psychological and social disturbances (Redline S, Strohl K, Otolaryngol Clin North Am, 132:303, 1999). A higher prevalence of sleep complaints has been described in the elderly (Vgontzas AN, Kales A, Annu Rev Med, 50:387-400, 1999). It is manifested by breathing disturbances during sleep, loud snoring, difficulties maintaining sleep, fatigue, daytime sleepiness, mood effects and impairment of daily activities (Lugaresi E, Cirignotta F, Zucconi M et al., Good and poor sleepers: an epidemiological survey of the San Marino population, Raven, New York, pp 1-12, 1983; Kales A, Soldatos CR, Kales JD, Am Fam Physician, 22:101-108, 1980). It has been associated with cardiovascular, endocrine and neurocognitive manifestations. Growing interest in early diagnosis and treatment has been noted in recent years based on emerging knowledge about the potential health consequences when the disease goes untreated (Nanen AM, Dunagan DP, Fleisher A et al., Chest, 121:1741, 2002). The veteran population in the mainland has a higher tendency for obesity, high blood pressure (HBP), sleep disorders and chronic alcohol consumption (Mustafa M, Erokwu N, Ebose I, Strohl K, Sleep Breath, 9:57-63, 2005). The Hispanic veteran population has never been studied in detail for sleep disorders and related conditions. We used previously validated screening tools for sleep disturbance breathing. Two hundred and forty-five questionnaires were administered. We found a higher prevalence of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) in our population compared with data from the mainland (USA). The mean age was 64 years (+/-11). Ninety seven per cent were males. The mean body mass index was 25 kg/cm(2); mean Epworth Sleepiness Scale score was 8. Thirty-four per cent met high-risk criteria for sleep apnea, 53% for insomnia, 13% for symptoms suggestive of narcolepsy and 13% for those suggestive of restless leg syndrome. There were high incidences of alcohol consumption (37.6%), diabetes (32.7%), hypercholesterolemia (31.8%), depression (31.8%), hypertension (39.6%) and post-traumatic stress disorder (PTSD) (9.8%).

The purpose of this study was to examine the prevalence, risk factors, and consequences of obesity in borderline patients 6 years after an index admission for psychiatric reasons. Two hundred and sixty-four borderline patients who met Revised Diagnostic Interview for Borderlines (DIB-R; Zanarini, Gunderson, Frankenburg, & Chauncy, 1989) and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. ref.) (DSM-III-R; APA, 1987) criteria for BPD were interviewed concerning their body mass index (BMI) and related medical problems. Seventy-four of the 264 borderline patients at 6-year follow up were obese, having a BMI > or = 30 kg/m2. They were significantly more likely than the nonobese patients to report suffering from diabetes, hypertension, osteoarthritis, chronic back pain, carpal tunnel syndrome, urinary incontinence, gastroesophageal reflux disorder, gallstones, and asthma. Four significant risk factors were found: chronic PTSD, lack of exercise, a family history of obesity, and a recent history of psychotropic polypharmacy. These results suggest that obesity is common among heavily treated borderline patients and is associated with a number of chronic medical disorders.

Although prior evidence exists concerning the association between posttraumatic stress disorder (PTSD) and cardiovascular disease, few studies have examined associations of PTSD symptomatology and the metabolic syndrome in the high stress occupation of police work. The metabolic syndrome is a clustering of cardiovascular disease risk factors that have also been independently associated with psychological conditions. The aim of this study was to examine associations between the PTSD symptoms and metabolic syndrome in police officers. A stratified sample of 115 police officers was randomly selected from the Buffalo, NY Police Department. PTSD symptoms were measured with the Impact of Event scale (IES), divided into categories of subclinical, mild, moderate and severe symptom levels. The metabolic syndrome was considered present if three or more of its component parameters (obesity, elevated blood pressure, reduced high density lipoprotein (HDL) cholesterol, elevated triglycerides, and abnormal glucose levels) were present in each officer. Results indicated a significantly increased prevalence of the metabolic syndrome among those officers in the severe PTSD symptom category compared with the lowest PTSD severity category (prevalence ratio (PR) = 3.31, 95% C.I. = 1.19 - 9.22). Adjustment for age did not alter the association appreciably (PR = 3.12, 95% C.I. = 1.15 - 8.50). Adjustment for several demographic and lifestyle factors (age, education, smoking, alcohol intake) reduced the magnitude of the prevalence ratio slightly for the severe versus subclinical PTSD category (PR = 2.69, 95% C.I. = 0. 79 - 9.13), with adjustment for age and education accounting for most of the attenuation (PR = 2.71, 95% C.I. = 0.99 - 7.37). Thus, officers with severe PTSD symptoms were approximately three times more likely to have the metabolic syndrome and education may account for some of this association.

Obesity (defined as body mass index (BMI) higher than 30), is a serious and global public health problem, associated with increased morbidity and mortality and it represents a risk factor for developing various somatic and psychiatric disorders. Combat-related posttraumatic stress disorder (PTSD) is frequently associated with increased BMI which leads to overweight and obesity. We therefore evaluated BMI in the ethnically uniform Croatian male participants of the Caucasian origin, combat exposed veterans with or without PTSD, controlled for the effect of trauma, age, smoking, alcohol consumption, physical activity and comorbid psychiatric disorders, and in age matched healthy control subjects. BMI did not differ significantly between veterans with or without PTSD and healthy control subjects, or when participants were subdivided according to the age groups, BMI categories, or the presence of psychiatric disorders. Limitation of the study might be a small number of veterans with or without PTSD. Similar BMI was found in Croatian male veterans with or without PTSD, and age matched healthy control subjects. The data provided evidence of overweight and obesity in large number of veterans but also in healthy control subjects, and indicated that public health organizations should develop more effective strategies to prevent overweight and obesity.

The relationships among the severity of childhood abuse and neglect, posttraumatic stress disorder (PTSD), and adult obesity were investigated. 207 women (M age = 26.5 yr., SD = 6.7) completed the Childhood Trauma Questionnaire, Millon Clinician Multiaxial Inventory, and a demographic questionnaire. Analyses of variance indicated that women who reported moderate-to-extreme emotional neglect (n = 71) had significantly higher PTSD scores and increased BMI compared to women who reported low emotional neglect (n = 84). Women who reported severe sexual or emotional abuse also had higher PTSD scores, but no relationship was found with BMI when other factors were controlled. Although PTSD scores and self-reported severity of childhood emotional neglect were strongly correlated (r = .61, p < .001), PTSD was not found to be a mediating factor in obesity in women who reported childhood emotional neglect, although depression was.

Much progress has been achieved in cannabinoid research. A major breakthrough in marijuana-cannabinoid research has been the discovery of a previously unknown but elaborate endogenous endocannabinoid system (ECS), complete with endocannabinoids and enzymes for their biosynthesis and degradation with genes encoding two distinct cannabinoid (CB1 and CB2) receptors (CBRs) that are activated by endocannabinoids, cannabinoids, and marijuana use. Physical and genetic localization of the CBR genes CNR1 and CNR2 have been mapped to chromosome 6 and 1, respectively. A number of variations in CBR genes have been associated with human disorders including osteoporosis, attention deficit hyperactivity disorder (ADHD), posttraumatic stress disorder (PTSD), drug dependency, obesity, and depression. Other family of lipid receptors including vanilloid (VR1) and lysophosphatidic acid (LPA) receptors appear to be related to the CBRs at the phylogenetic level. The ubiquitous abundance and differential distribution of the ECS in the human body and brain along with the coupling to many signal transduction pathways may explain the effects in most biological system and the myriad behavioral effects associated with smoking marijuana. The neuropharmacological and neuroprotective features of phytocannabinoids and endocannabinoid associated neurogenesis have revealed roles for the use of cannabinoids in neurodegenerative pathologies with less neurotoxicity. The remarkable progress in understanding the biological actions of marijuana and cannabinoids have provided much richer results than previously appreciated cannabinoid genomics and raised a number of critical issues on the molecular mechanisms of cannabinoid induced behavioral and biochemical alterations. These advances will allow specific therapeutic targeting of the different components of the ECS in health and disease. This review focuses on these recent advances in cannabinoid genomics and the surprising new fundamental roles that the ECS plays in the retrograde signaling associated with cannabinoid inhibition of neurotransmitter release to the genetic basis of the effects of marijuana use and pharmacotherpeutic applications and limitations. Much evidence is provided for the complex CNR1 and CNR2 gene structures and their associated regulatory elements. Thus, understanding the ECS in the human body and brain will contribute to elucidating this natural regulatory mechanism in health and disease.

Persons with schizophrenia and post-traumatic stress disorder (PTSD) tend to have higher psychiatric and somatic morbidity. They typically have higher rates of substances abuse (including smoking), more prevalent obesity, diabetes mellitus, and cardiovascular disease (CVD). This is especially well seen in case of the metabolic syndrome, with a number of published studies on psychiatric patients in the last few years. This study investigated the associations between metabolic syndrome, anxiety, depression and suicidal tendency in schizophrenic and combat-related PTSD patients controlled by healthy controls. Higher rates of anxiety, depression and recent life changes scores in participants with metabolic syndrome were recorded compared to those without metabolic syndrome. Suicidal tendencies were equally present in both groups.

The gradual emergence of symptoms following exposure to traumatic events has presented a major conceptual challenge to psychiatry. The mechanism that causes the progressive escalation of symptoms with the passage of time leading to delayed onset post-traumatic stress disorder (PTSD) involves the process of sensitization and kindling. The development of traumatic memories at the time of stress exposure represents a major vulnerability through repeated environmental triggering of the increasing dysregulation of an individual's neurobiology. An increasing body of evidence demonstrates how the increased allostatic load associated with PTSD is associated with a significant body of physical morbidity in the form of chronic musculoskeletal pain, hypertension, hyperlipidaemia, obesity and cardiovascular disease. This increasing body of literature suggests that the effects of traumatic stress need to be considered as a major environmental challenge that places individual's physical and psychological health equally at risk. This broader perspective has important implications for developing treatments that address the underlying dysregulation of cortical arousal and neurohormonal abnormalities following exposure to traumatic stress.

The aim of this study is to examine relationships of sleep duration with sociodemographic and health-related factors, psychiatric disorders and sleep disturbances in a nationwide sample in Korea. A total of 6510 subjects aged 18-64 years participated in this study. Logistic regression was used to calculate the odd ratios and 95% confidence intervals of the covariates, psychiatric disorders and sleep disturbances across the following sleep duration categories: 5 h or less, 6, 7, 8 and 9 h or more per day. Low levels of education, unemployment and physical illness were associated with sleeping for 5 h or less and 9 h or more. Being older and widowed/divorced/separated, high levels of physical activity, pain/discomfort, obesity and high scores on the General Health Questionnaires were associated with sleeping for 5 h or less. Female, being younger and underweight were associated with sleeping for 9 h or more. Alcohol dependence, anxiety disorder and social phobia were associated significantly with sleeping for 5 h or less and 9 h or more. Other psychiatric disorders were more common in subjects who slept for 5 h or less (e.g. alcohol use disorder, mood disorder, major depressive disorder, dysthymic disorder, obsessive-compulsive disorder and specific phobia) or 9 h or more (e.g. post-traumatic stress disorder). In addition, subjects who slept for 5 h or less reported more sleep disturbances than did subjects who slept for 7 h. Short or long sleep is associated with psychiatric disorders and/or sleep disturbance, therefore attention to the mental health of short or long sleepers is needed.

The prevalence rates of obesity and metabolic syndrome are on the rise in the United States. Epidemiological surveys suggest that the rates of these medical conditions are especially high among persons with psychiatric disorders, including post-traumatic stress disorder (PTSD). A variety of factors are thought to contribute to the risk for metabolic syndrome, including excessive caloric intake, decreased activity and energy expenditure, use of certain medications, stress and genetic influences. Recent research demonstrates that stress, acting through the neuropeptide Y (NPY) and glucocorticoid systems, potentiates the development of obesity and other aspects of metabolic syndrome in mice fed a high caloric, fat and sugar diet. Alterations in the NPY and glucocorticoid systems also impact behavioral adaptation to stress, as indicated by studies in animals and persons exposed to severe, life-threatening or traumatic stress. The following review examines the biology of the NPY and neuroactive steroid systems as physiological links between metabolic syndrome and PTSD, a paradigmatic neuropsychiatric stress disorder. Hopefully, understanding the function of these systems from both a translational and systems biology point of view in relation to stress will enable development of more effective methods for preventing and treating the negative physical and mental health consequences of stress.
