Objective: To assess psychiatric morbidity, personality profiles and saliva cortisol levels in overweight and obese individuals at dietician clinic. Method: This cross-sectional study is based on individuals who attended dietician clinic between June to November 2008. They had completed questionnaires that included General Health Questionnaire 30-items, assessment for psychiatric illness using Structured Clinical Interview for DSM-IV and personality profiles using Personality Assessment Schedule. Saliva and body mass index were taken. Results: Of the 102 patients, 16 (15.7%) were diagnosed to have psychiatric illness. There were no differences between obese and overweight patients in terms of personality traits and psychological problem. Presence of psychiatric illness was associated with higher mean body mass index. Saliva cortisol levels were not elevated in patients who had psychiatric illness. Conclusions: Psychiatric illnesses are common in individuals who seek weight treatment. Careful psychological evaluation is important at (or before) commencement of a diet program.
Obesity is highly prevalent among patient with schizophrenia. It is therefore important to know whether lifestyle factors could contribute to obesity. The objective of this paper is to study the prevalence of overweight, obesity and high waist circumference (WC) in relation to Binge eating and lifestyle factors among patients with schizophrenia. This is a cross sectional study for a period of three and a half months which systematically selected patients with schizophrenia who fulfilled the inclusion criteria. The diagnosis of schizophrenia was made using Structured Clinical Interview for DSM-IV (SCID). The diagnosis of Binge Eating Disorder (BED) and the assessment of lifestyle factors were made using Eating Disorder, Module H of SCID and Health Promoting Lifestyle Profile II (HPLP II) respectively. The prevalence of overweight was 39.2 %, obesity was 35.1 % and high waist circumference was 63.9 %. The difference between presence of BED among patients who had normal and either overweight or obese was not significant (?2 with Yates correction 3.34, p=0.06). BED was found to be more in patients with high WC (n=11, 78.6 %) than those with normal WC (n=3, 21.4 %) but the difference was not significant (?2=1.88, p=0.21). In term of lifestyle factors, no significant different found between those who smoke and those who did not smoke in relation to BMI (?2=0.00, p=0.98) and WC (?2=0.15, p=0.90). There was no difference between total score of diet and exercise among patients who had normal weight and those who were either overweight or obese in relation to BMI (t=1.30, p=0.20) and WC (t=0.91, p=0.36) and BMI (t=0.80, p=0.43) and WC (t=0.02, p=0.98) respectively. There were also no differences between total score of all four domains of psychological lifestyle i.e. stress management, health responsibility, spiritual growth and interpersonal relationship among patients who had normal weight and those who were overweight and obese in relation to BMI and WC (p>0.05). Presence of Binge eating disorder and the lifestyle factors did not contribute to obesity among patients with schizophrenia. Keywords: Schizophrenia, obesity, lifestyle, binge eating disorder
Objective: To determine the prevalence of depressive disorders among caregivers of patients with schizophrenia, its association with patient’s and caregiver’s socio-demographic characteristics and family functioning.
Methods: This was a cross-sectional study of caregivers of patients with schizophrenia at the outpatient clinic, Hospital Permai Johor Bahru, Malaysia. The study was conducted between August and October 2008. A total of 243 caregivers who fulfilled the inclusion criteria were enrolled, of whom 232 completed the self-administered socio-demographic questionnaire, the General Health Questionnaire (GHQ-30) and the McMaster Family Assessment Device. A total of 33 caregivers with the GHQ-30 cut-off point of 7/8 were assessed further by the Mini International Neuropsychiatric Interview to diagnose depressive disorder.
Results: The prevalence of psychological distress in our study sample was 14% (n = 33) and that of depressive disorders was 6% (n = 14). There was no association between patients’ and caregivers’ sociodemographic characteristics with depressive disorders, but there were significant associations between depressive disorders and family functioning dimensions in terms of Communication and Roles.
Conclusion: Although the causal link was not established, the results suggested that depression had a significant association with family functioning among caregivers of patients with schizophrenia.

We present the results and conclusions of an observational prospective cohort design study using self-administered questionnaires to determine correlation between psychosocial factors and cancer outcome among 80 consecutive newly diagnosed treatment naïve cancer subjects who were being referred to the Oncology Clinic, Hospital Universiti Kebangsaan Malaysia. Subjects were recruited over a period of 43 weeks from October 2000 till July 2001. Follow-up assessments were carried out at 6-months and 12 to 26 months later. The prediction of survival time was performed by the Cox Regression Analysis method with adjustments for biological and psychosocial risk factors. It was noted that depression (p = 0.001), stage 4 cancer disease (p = 0.016), neurological (p = 0.032), gastrointestinal tract (p = 0.04), head and neck (p = 0.011), gynaecological (p = 0.005) and bone and soft tissue (p = 0.030) malignancies were independent and statistically significant prognostic factor of survival during the study period. It was further shown than depressed patients were found to have almost four fold greater risk of dying than non-depressed patients and patients with stage 4 cancer illness have a five fold greater risk of dying than patients with stage 1 disease. Furthermore, based on tumour types subjects with neurological, gynaecological, head and neck, bone and soft tissue and gastro intestinal tract malignancies were found to have approximately thirty-six, twenty-five, twenty-two, sixteen and seven fold greater risk of dying respectively when compared to subjects with genitourinary cancers. This study further affirms the need for health care providers to be aware of the psychological aspects of the cancer patient and provide appropriate therapy so as to ensure that this group of individuals would have enhanced survival rates.

Normal rats, on being repetitively stressed by being restrained in a tight container for two hours, had higher levels of plasma corticosterone compared to pre stress values. These rats also reacted to the stress by a behavioral response in which there was marked decrease in locomotor activity assessed by the open field test (pre stress: 71.3 +/- 2.6 squares crossed versus post stress: 14.3 +/- 2.5 squares crossed) by counting the number of squares entered by the rat over 5 minutes. By the 6th to 7th exposures to the repetitive stress, the rats adapted to the stress and had normal plasma corticosterone levels and locomotor activity scores comparable to the pre stress values. These responses to stress were completely blocked by the administration of 0.32 microg/100 g BW of naloxone i.p at 10 minutes prior to the stress. In rats fed with rat chow supplemented with 90 mg/kg rat chow or 150 mg/kg rat chow of vitamin E, there was significant reduction of the plasma corticosterone levels and improvement in the locomotor activity. Stress thus caused opioid mediated increase in plasma corticosterone and reduction in locomotor activity which could be blocked by naloxone. These stress responses probably also involved generation of oxygen free radicals which were scavenged by the vitamin E, thus reducing the effects of repetitive stress on locomotor activity and serum corticosterone levels.
1. This study was carried out to determine the effect of short-term and long-term ingestion of glycyrrhizic acid on the response to 2 h of restraint stress by measuring locomotor activity and plasma corticosterone levels. 2. Male Sprague-Dawley rats were randomly assigned into four groups, each group having eight rats. Group 1 (control) was given ordinary tap water, while groups 2 (short term), 3 and 4 (both long term) were given tap water containing 1 mg/mL glycyrrhizic acid to drink for 10 days, 4 weeks and 9 weeks, respectively. All the rats were subjected to 2 h of restraint stress and the locomotor activity assessed using an activity test in an open field arena followed by blood sampling to determine the plasma corticosterone level. These procedures were repeated daily for 14 days. 3. The basal locomotor activity scores for rats given glycyrrhizic acid for 10 days or 4 weeks were similar to those of controls; however, that of the rats treated long term with glycyrrhizic acid was significantly lower (21.0 +/- 3.0 squares crossed; P < 0.0005). Following the first period of restraint stress there was a highly significant decrease in locomotor activity, which remained significantly lower until the seventh and subsequent periods, indicating an adaptation to the repeated stress had occurred. Although the decrease in locomotor activity was partially blocked and adaptation to repetitive stress was enhanced in the rats given glycyrrhizic acid for 10 days, this was not seen in rats treated with glycyrrhizic acid for 4 or 9 weeks. The corticosterone levels in control rats were significantly elevated for 4-5 days following the exposure to repetitive stress but decreased gradually from day 7 onwards. However, both short- and long-term glycyrrhizic acid-treated rats had higher plasma corticosterone levels than the controls (P < 0.05). 4. In conclusion, repetitive restraint stress caused decreased locomotor activity associated with increased plasma corticosterone levels, both of which, in normal rats, decreased with adaptation to stress. The stress response was partially blocked and adaptation enhanced in rats given glycyrrhizic acid for 10 days, but not in rats given glycyrrhizic acid for 4 and 9 weeks. Glycyrrhizic acid ingestion caused high plasma corticosterone.
1. The present study examined the effect of naloxone (NAL), glycyrrhizic acid (GCA), deoxycorticosterone (DOC) and dexamethasone (DEX) on daily repeated 2 h chronic restrained stress (RS) on the locomotor activity (LA) of rats tested in the open field arena to elucidate the possible roles of opioids, glucocorticoids and mineralocorticoids in response to stress. 2. Intact and adrenalectomized (ADX) rats were either injected with 0.1 mL of NAL (0.32 microgram/100 g BW), 2.4 mg/kg DOC or 120 micrograms/kg DEX or had 1.0 mg/mL GCA dissolved in their drinking water or normal saline (for the ADX group) dissolved in their drinking water. 3. In intact groups, treatment with NAL completely blocked the stress response and treatment with GCA, DOC and DEX partially prevented the stress response. Adaptation occurred on either days 4, 5, 6 or 7 for intact rats treated with DEX, DOC, GCA or control rats, respectively. All ADX control rats died following the first 2 h RS. Adrenalectomized rats treated with DEX or DOC adapted later compared with intact rats, while rats given either GCA or NAL were unable to block or adapt to chronic RS. 4. These findings demonstrate that the stress response is primarily mediated by endogenous opioids, in that it is blocked by NAL. Both mineralocorticoids and glucocorticoids, which can act centrally to inhibit endorphins, partially blocked the stress response. The effect of GCA in intact rats was similar to that of both DEX and DOC in intact rats. Adrenalectomized rats treated with GCA (despite their lack of endogenous corticosterone) showed a stress response that was significantly different from the other ADX groups, implying that GCA had effects independent of endogenous corticosterone.
