Impact of childhood adversities on specific symptom dimensions in first-episode psychosis.

BACKGROUND: The relationship between childhood adversity (CA) and psychotic disorder is well documented. As the adequacy of the current categorical diagnosis of psychosis is being increasingly questioned, we explored independent associations between different types of CA and specific psychotic symptom dimensions in a well-characterized sample of first-episode psychosis (FEP) patients. METHOD: This study involved 236 FEP cases aged 18-65 years who presented for the first time to psychiatric services in South London, UK. Psychopathology was assessed with the Positive and Negative Syndrome Scale and confirmatory factor analysis was used to evaluate the statistical fit of the Wallwork/Fortgang five-factor model of psychosis. CA prior to 17 years of age (physical abuse, sexual abuse, parental separation, parental death, and being taken into care) was retrospectively assessed using the Childhood Experience of Care and Abuse Questionnaire. RESULTS: Childhood sexual abuse [ß = 0.96, 95% confidence interval (CI) 0.40-1.52], childhood physical abuse (ß = 0.48, 95% CI 0.03-0.93) and parental separation (ß = 0.60, 95% CI 0.10-1.11) showed significant associations with the positive dimension; while being taken into care was associated with the excited dimension (ß = 0.36, 95% CI 0.08-0.65), independent of the other types of CA. No significant associations were found between parental death and any of the symptom dimensions. CONCLUSIONS: A degree of specificity was found in the relationships between different types of CA and psychosis symptom dimensions in adulthood, suggesting that distinct pathways may be involved in the CA-psychosis association. These potentially different routes to developing psychosis merit further empirical and theoretical exploration.

Clinical correlates of vitamin D deficiency in established psychosis.

BACKGROUND: Suboptimal vitamin D levels have been identified in populations with psychotic disorders. We sought to explore the relationship between vitamin D deficiency, clinical characteristics and cardiovascular disease risk factors among people with established psychosis. METHODS: Vitamin D levels were measured in 324 community dwelling individuals in England with established psychotic disorders, along with measures of mental health, cardiovascular risk and lifestyle choices. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D (25-OHD) levels below 10 ng/ml (equivalent to <25 nmol/L) and "sufficient" Vitamin D as above 30 ng/ml (>50 nmol/L). RESULTS: The mean 25-OHD serum level was 12.4 (SD 7.3) ng/ml, (range 4.0-51.7 ng/ml). Forty nine percent (n = 158) were vitamin D deficient, with only 14 % (n = 45) meeting criteria for sufficiency. Accounting for age, gender, ethnicity and season of sampling, serum 25-OHD levels were negatively correlated with waist circumference (r = -0.220, p < 0.002), triglycerides (r = -0.160, p = 0.024), total cholesterol (r = -0.144, p = 0.043), fasting glucose (r = -0.191, p = 0.007), HbA1c (r = -0.183, p = 0.01), and serum CRP levels (r = -0.211, p = 0.003) and were linked to the presence of metabolic syndrome. CONCLUSIONS: This is the largest cross sectional study of serum 25-OHD levels in community dwelling individuals with established psychosis, indicating a high level of vitamin D deficiency. Lower vitamin D levels are associated with increased cardiovascular disease risk factors and in particular metabolic syndrome. Further research is needed to define appropriate protocols for vitamin D testing and supplementation in practice to see if this can improve cardiovascular disease risk.

Cardiovascular risk factors and metabolic syndrome in people with established psychotic illnesses: baseline data from the IMPaCT randomized controlled trial.

BACKGROUND: The aims of the study were to determine the prevalence of cardiometabolic risk factors and establish the proportion of people with psychosis meeting criteria for the metabolic syndrome (MetS). The study also aimed to identify the key lifestyle behaviours associated with increased risk of the MetS and to investigate whether the MetS is associated with illness severity and degree of functional impairment. METHOD: Baseline data were collected as part of a large randomized controlled trial (IMPaCT RCT). The study took place within community mental health teams in five Mental Health NHS Trusts in urban and rural locations across England. A total of 450 randomly selected out-patients, aged 18-65 years, with an established psychotic illness were recruited. We ascertained the prevalence rates of cardiometabolic risk factors, illness severity and functional impairment and calculated rates of the MetS, using International Diabetes Federation (IDF) and National Cholesterol Education Program Third Adult Treatment Panel criteria. RESULTS: High rates of cardiometabolic risk factors were found. Nearly all women and most men had waist circumference exceeding the IDF threshold for central obesity. Half the sample was obese (body mass index ≥ 30 kg/m2) and a fifth met the criteria for type 2 diabetes mellitus. Females were more likely to be obese than males (61% v. 42%, p < 0.001). Of the 308 patients with complete laboratory measures, 57% (n = 175) met the IDF criteria for the MetS. CONCLUSIONS: In the UK, the prevalence of cardiometabolic risk factors in individuals with psychotic illnesses is much higher than that observed in national general population studies as well as in most international studies of patients with psychosis.

Sexual dysfunction and central obesity in patients with first episode psychosis.

BACKGROUND: In recent years the association between sexual dysfunction (SD) and obesity in the general population has drawn major attention. Although sexual dysfunction is common in psychosis, its relationship with weight gain and obesity remains unclear. AIMS: To investigate the association between sexual dysfunction and obesity in a cohort of patients with first episode psychosis. METHOD: Sexual function was assessed in a cohort of patients with first episode psychosis using the Sexual Function Questionnaire (SFQ). Anthropometric measures, including weight, BMI, waist, waist-hip ratio were investigated. Additionally, leptin and testosterone were investigated in male patients. RESULTS: A total of 116 patients (61 males and 55 females) were included. Of these 59% of males and 67.3% of females showed sexual dysfunction (SD) according to the SFQ. In males, higher SFQ scores were significantly correlated with higher BMI (Std. ß=0.36, P=0.01), higher leptin levels (Std. ß=0.34, P=0.02), higher waist-hip ratio (Std. ß=0.32, P=0.04) and lower testosterone levels (Std. ß=-0.44, P=0.002). In contrast, in females, SFQ scores were not associated with any of these factors. CONCLUSIONS: While sexual dysfunction is present in both female and male patients with their first episode of psychosis, only in males is sexual dysfunction associated with increased BMI and waist-hip ratio. The association between SD, BMI, low levels of testosterone and high levels of leptin suggest that policies that lead to healthier diets and more active lifestyles can be beneficial at least, to male patients.

Provision of health promotion programmes to people with serious mental illness: a mapping exercise of four South London boroughs.

BACKGROUND: People with serious mental illness (SMI) are at increased risk of developing various physical health diseases, contributing to significantly reduced life expectancies compared with the general population. In light of this, the Department of Health have set the physical health of people with mental health problems as a priority for improvement. Additionally, the UK government encourages the NHS and local authorities to develop health promotion programmes (HPPs) for people with SMI. AIMS: To document how many and what types of HPPs were available to people with SMI across four South London boroughs, UK. RESULTS: We found 145 HPPs were available to people with SMI across the four boroughs, but with an inequitable distribution. We also found that certain HPPs set admission criteria that were likely to act as a barrier to improving health. CONCLUSIONS: A more integrated approach of documenting and providing information regarding the provision of HPPs for or inclusive of people with SMI is needed. ABSTRACT: People with serious mental illness (SMI) such as schizophrenia, schizoaffective disorders and bipolar disorder are at increased risk of developing diabetes, cardiovascular disease and respiratory disease, contributing to significantly reduced life expectancies. As a result, emphasis has been placed on developing Health Promotion Programmes (HPPs) to modify the risk of poor physical health in SMI. We examined how many and what types of HPPs are available for or inclusive of people with SMI across four borough in South London, UK. A cross-sectional mapping study was carried out to identify the number of HPPs available to people with SMI. We found 145 HPPs available to people with SMI existed across the four boroughs but with an inequitable distribution, which in some boroughs we anticipate may not meet need. In some cases, HPPs set admission conditions which were likely to further impede access. We recommend that accurate and readily available information on the provision of HPPs for or inclusive of people with SMI is needed.
