Negative affect moderates the link between body image dissatisfaction and disordered eating among psychiatric outpatients in a multi-ethnic Asian setting.

INTRODUCTION: Few studies have investigated the factors that affect the relationship between body image dissatisfaction and disordered eating locally. Our study aimed to investigate the moderating effects of depression and anxiety levels on the body dissatisfaction-disordered eating link in Singapore. METHODS: A total of 329 participants completed a set of questionnaires that included various scales pertaining to eating behaviours, body image, psychological distress and quality of life. RESULTS: Participants were diagnosed with schizophrenia (47.4%), depression (46.8%) and substance use disorders (5.8%). Moderation analyses revealed that depression (F [9, 251] = 18.50, p < 0.001, R2 change = 0.021) and anxiety levels (F [9, 268] = 19.54, p < 0.001, R2 change = 0.014) were significant moderators of the relationship between body dissatisfaction and disordered eating scores. Subsequent multivariate linear logistic regression analyses showed that high disordered eating scores were significantly associated with lower physical (F [8, 273] = 9.59, R2 = 0.22, p < 0.001, ß = -0.27, p < 0.001), psychological (F [8, 273] = 10.51, R2 = 0.49, p < 0.001, ß = -0.27, p < 0.001), social (F [8, 256] = 6.78, R2 = 0.18, p < 0.001, ß = -0.18, p = 0.004) and environment (F [8, 273] = 5.29, R2 = 0.13, p < 0.001, ß = -0.19, p = 0.001) quality of life scores after controlling for sociodemographic covariates. CONCLUSION: Greater effort should be dedicated to the screening of disordered eating behaviours in psychiatric outpatients presenting with greater psychological distress.

Hazardous alcohol use among patients with schizophrenia and depression.

AIMS: The current study aimed to 1) report the prevalence of hazardous alcohol use in an outpatient population among those with schizophrenia and depressive disorders, 2) assess the sociodemographic and clinical correlates of hazardous alcohol use, 3) examine the association of hazardous alcohol use with severity of depression, anxiety and smoking, and 4) assess the association of hazardous alcohol use with quality of life. METHODS: Three hundred ten outpatients seeking treatment at a tertiary psychiatric institute with a diagnosis of either schizophrenia spectrum disorder or depressive disorder were included in the study. Patients were assessed for hazardous alcohol use using the Alcohol Use Disorders Identification Test. Information on sociodemographic correlates, clinical history, severity of symptoms of depression and anxiety, as well as quality of life (QOL) was collected. RESULTS: The overall prevalence of hazardous alcohol use among the sample was 12.6%. The prevalence of hazardous alcohol use among patients with depression and schizophrenia was 18.8% and 6.4%, respectively. Compared to those who were students, patients who were gainfully employed or unemployed were more likely to engage in hazardous alcohol use (Odds Ratio (OR) = 5.5 and 7.7, respectively). Patients with depression compared to those with schizophrenia (OR = 11.1) and those who were current smokers compared to those who had never smoked (OR = 14.5) were more likely to engage in hazardous alcohol use. Hazardous alcohol use was associated with lower QOL in the physical health domain (p = 0.002). CONCLUSION: Given the significant prevalence of hazardous alcohol use in this population, routine screening for hazardous alcohol use and brief interventions could be an effective way of managing this comorbidity. There is a need to develop and evaluate culturally appropriate brief interventions based on patient preference in this setting.

Microsporidial keratoconjunctivitis after rugby tournament, Singapore.

We investigated an outbreak of 47 probable and 6 confirmed cases of microsporidial keratoconjunctivitis involving participants of an international rugby tournament in Singapore in April 2012.The mode of transmission was eye contact with soil. Vittaforma corneae was identified in 4 of 6 corneal scrapings and in 1 of 12 soil water samples.

Epidemiology of acute hepatitis E in Singapore.

OBJECTIVES: We undertook an epidemiological review to determine the trend and characteristics of acute hepatitis E in Singapore over the last 12 years. METHODS: We analysed the epidemiological records of all laboratory-confirmed cases of acute hepatitis E maintained at the Communicable Diseases Division, Ministry of Health, from 2000 to 2011. RESULTS: A total of 540 laboratory-confirmed cases of acute hepatitis E was reported with more than half imported, mainly from India and Bangladesh. Among the indigenous cases, the mean annual incidence per 100,000 population increased from 0.05 in 2000-2002 to 0.92 in 2009-2011. There was a male predominance and the median age was 46 years. Among the 3 major ethnic groups of Singapore residents, Chinese and Indians had higher mean annual incidence rate compared to Malays. All the indigenous cases occurred singly and sporadically and could not be epidemiologically linked to one another by person, place or time. No common food item was implicated. CONCLUSIONS: Indigenous acute hepatitis E has emerged as a major cause of acute viral hepatitis in Singapore. While epidemiological investigations are ongoing to elucidate the risk factors and modes of transmission, travellers should be reminded to practise a high standard of personal and food hygiene when visiting endemic countries.
