Long Term Follow-Up of Metabolic Syndrome in Patients with Severe Mental Illness among Korean Population : A 10-Year Follow-Up Study (2011-2020) / 생물치료정신의학

Objectives@#：This study was aimed to investigate the changes in metabolic syndrome (MetS) status and long-term impact of its components over a 10-year period in severe mental illness (SMI) patients in a national mental hospital. @*Methods@#：A total of 93 patients (schizophrenia=88, bipolar disorder=5) who met the diagnosis of Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) and participated in the MetS study in 2011 were included. MetS was defined by revised National Cholesterol Education Program-Adult Treatment Panel III (revised NCEP-ATP-III) guidelines. @*Results@#：The prevalence of MetS was significantly increased from 40.9% in 2011 to 60.2% in 2020. There were significant differences in admission status and hospitalization months, compared to the groups with and without MetS. Upon reviewing the changes over a decade, systolic blood pressure (SBP) was a significant factor in the group without MetS. In the group with MetS, SBP, waist circumference, and BMI (body mass index) were significant factors. Multiple logistic regression analysis revealed that hospitalization during follow-up periods [odds ratio (OR)=0.969, 95% confidence interval (CI): 0.948-0.991] and BMI (OR=1.426, 95% CI: 1.196-1.701) were significantly associated with MetS in subjects. @*Conclusion@#：The prevalence of MetS in patients with SMI significantly increased over time. The admission status and hospitalization were also confirmed to be the significant values of MetS.

Predictors of Metabolic Syndrome in Chronic Schizophrenic Patients Followed for 5 Years(2011-2016) / 정신신체의학

OBJECTIVES: To investigate changes in, and predictors of, metabolic syndrome(MetS) status over a 5-year period in chronic schizophrenic patients and to identify factors associated with the prevention of or recovery from MetS. METHODS: In total, 107 patients, all of whom provided written informed consent, were followed from 2011 to 2016 at Naju National Hospital for this study. MetS was defined according to the revised National Cholesterol Education Program-Adult Treatment Panel III guidelines. RESULTS: During follow-up period, 22(20.5%) patients were newly diagnosed to MetS, 14(13.1%) were disappeared, 77(66.4%) were not changed[MetS : 34(31.8%), No MetS 37(34.6%)]. Common significant factors in the two changed groups were triglyceride and waist circumference, not dose and type of antipsychotic medication. Multiple logistic regression analysis revealed that female gender(odds ratio[OR]=2.846, 95% confidence interval[CI] : 1.020-7.942), attending two or more outpatient visits per month(OR=3.155, 95% CI : 1.188-8.379) and taking antidepressant medication(OR=3.991, 95% CI : 1.048-15.205) were significantly associated with MetS after controlling for other confounding variables. Type and dose of antipsychotic medication were not significantly associated with MetS. CONCLUSIONS: Triglyceride and waist circumference were important manageable indicator of MetS. Adoption of a healthy lifestyle is more important than adjusting the dose or type of antipsychotic medication in the treatment of chronic schizophrenia patients with MetS.

Moderating Effect of Stress Coping Strategies on the Relationship between a National Statistics Office Workers' Occupational Stress and Mental Health / 신경정신의학

OBJECTIVES: This study examined the moderating effects of stress coping strategies on the relationship between occupational stress of national statistical office workers and mental health. METHODS: Subjects were 133 workers at a regional statistics office. Occupational stress, stress coping strategies, and mental health were examined using the Korean Occupational Stress Scale (KOSS), Ways of Coping Checklist, and The Symptom Check-List-90-R. Stress coping strategies were composed of problem-focused coping, social support coping, emotion-focused coping, and wishful thinking coping. RESULTS: Moderated regression indicated that the social support coping and emotion-focused coping style positively moderated the relationship between occupational stress and mental health in national statistical office workers. The social support coping style positively moderated the relationship between interpersonal conflict (KOSS subscale) and mental health in national statistical office workers. The emotion-focused coping style positively moderated the relationship between job insecurity (KOSS subscale) and mental health in national statistical office workers. The emotion-focused coping style negatively moderated the relationship between job demand (KOSS subscale) and mental health in national statistical office workers. CONCLUSION: The implications of this study included that negative results due to high occupational stress can be varied by use of suitable stress coping strategies.

Prevalence and Its Correlates of Night Eating Syndrome in Schizophrenic Outpatients / 정신신체의학

OBJECTIVES: The aim of study was to examine the prevalence of night eating syndrome(NES) and its correlates in schizophrenic outpatients. METHODS: The 14 items of self-reported night eating questionnaire(NEQ) was administered to 201 schizophrenic patients in psychiatric outpatient clinic. We examined demographic and clinical characteristics, body mass index(BMI), subjective measures of mood, sleep, binge eating, and weight-related quality of life using Beck's Depression Inventory(BDI), Pittsburgh Sleep Quality Index(PSQI), Binge Eating Scale(BES) and Korean version of Obesity-Related Quality of Life Scale(KOQoL), respectively. RESULTS: The prevalence of night eaters in schizophrenic outpatients was 10.4%(21 of 201). Comparisons between NES group and non-NES group revealed no significant differences in sociodemographic characteristics, clinical status and BMI. Compared to non-NES, patients with NES reported significantly greater depressed mood and sleep disturbance, more binge eating pattern, and decreased weight-related quality of life. While 'morning anorexia' and 'delayed morning meal'(2 of 5 NES core components in NEQ) were not differed between groups, 'nocturnal ingestions', 'evening hyperphagia', and 'mood/sleep' were more impaired in NES group. CONCLUSION: These findings are the first to describe the prevalence and its correlates of night eaters in schizophrenic outpatients. These results suggest that NES has negative mental health implications, although it was not associated with obesity. Further study to generalize these results is required.

Clinical Characteristics of Night Eating Syndrome in Outpatients with Bipolar Disorder / 정신신체의학

OBJECTIVES: The aim of this study is to evaluate the clinical characteristics of night eating syndrome(NES) in bipolar disorder outpatients. METHODS: The 14 items of self-reported night eating questionnaire(NEQ) was administered to 84 bipolar patients in psychiatric outpatient clinic. We examined demographic and clinical characteristics, body mass index(BMI), subjective measures of mood, sleep, binge eating & weight-related quality of life using Beck's Depression Inventory (BDI), Pittsburgh Sleep Quality Index(PSQI), Binge Eating Scale(BES) and Korean version of Obesity-Related Quality of Life Scale(KOQoL), respectively. RESULTS: The prevalence of night eating syndrome in bipolar outpatients was 14.3%(12 of 84). Comparisons between NES group and non-NES group revealed no significant differences in demographic characteristics, BMI and clinical status except economic status and comorbid medical illnesses. However, compared to non-NES, patients with NES was more likely to have binge eating pattern and poorer weight-related quality of life. CONCLUSIONS: This study is to be the first to describe the clinical correlates of night eaters in bipolar outpatients. Although there were few significant correlates of NES in bipolar outpatients, relatively high prevalence of NES suggest that clinicians should be aware to assess the patients with bipolar disorder on NES, regardless of obesity status of patients.

Prevalence and Its Correlates of Restless Legs Syndrome in Outpatients with Bipolar Disorders / 정신신체의학

OBJECTIVES: This study was to assess the prevalence and its correlates of restless legs syndrome(RLS) in outpatients with bipolar disorder. METHODS: A total of 100 clinical stabilized bipolar outpatients were examined. The presence of RLS and its severity were assessed using the International Restless Legs Sydrome Study Group(IRLSSG) diagnostic criteria. Beck's Depression Inventory(BDI), Spielberg's State Anxiety Inventory(STAI-X-1), Pittsburgh Sleep Quality Index(PSQI), Korean version Drug Attitude Inventory(KDAI-10), Subjective Well-Beings under Neuroleptic Treatment Scale-Short Form(SWN-K) and Barnes Akathisia Rating Scale(BARS) were used to evaluate the depressive symptomatology, level of anxiety, subjective quality of sleep, subjective feeling of well-being, drug attitude, presence of akathisia, respectively. RESULTS: Of the 100 bipolar outpatients, 7(7%) were met to full criteria of IRLSSG and 36(36%) have at least one of the 4 IRLSSG criterion. Because of relatively small sample size, non-parametric analysis were done to compare the characteristics among 3 groups(full-RLS, 1> or =positive RLS-symptom and Non-RLS). There were no significant differences in sex, age, and other sociodemographic and clinical data among 3 groups. BDI, STAI-X-1 and PSQI are tended to be impaired in RLS and 1> or =positive RLS-symptom groups. CONCLUSIONS: This is the first preliminary study for studying the prevalence and its correlates of RLS in bipolar disorder. The results shows that relatively small proportion of RLS was present in bipolar disorder patients when compared to patients with schizophrenia. Same tendencies shown in schizophrenic patients were found that bipolar patients with RLS had more depressive symptoms, state anxiety and poor subjective sleep quality. Further systematic studies may be needed to find the characteristics of RLS in bipolar patients.

The Effect of Weight Reduction on the Obesity-Related Quality of Life, Physical and Emotional Well-Being in Obese Schizophrenic Inpatients / 대한정신약물학회지

OBJECTIVE: The purpose of this study was to assess the effect of the weight reduction program designed for schizophrenic patients. It's effects were assessed especially in the aspects of the obesity-related quality of life, emotional and physical well-being of the patients. METHODS: Fifty-one obese schizophrenic inpatients were enrolled in a 12-week, randomized weight reduction program. Thirty-two patients were randomly assigned to an intervention group in which they received the weight management program. Nineteen patients were allocated to the control group in which they received the usual clinical inpatient treatments. Body weight, Body Mass Index (BMI) and Quality of Life Scales such as Short Form of Medical Outcome Study (SF-36), Korean version of Obesity-related Quality of Life Scale (KOQOL) and Korean version of Body Weight, Image and Self-Esteem Evaluation Questionnaire (B-WISE-K) were evaluated during 12-week period. All assessments were done at baseline, 4, 8 and 12 week. Repeated measures of analysis of variance and post-hoc comparisons were done to compare the group differences from baseline at each visit. RESULTS: Sixteen of 32 (50%) patients in intervention group and 12 of 19 (69.4%) patients in control group completed this study. We found significant group by time interaction effects in weight, BMI and waist circumferences (p<0.05, respectively). The weight changes from baseline to 8 week and 12 week were significant in post-hoc comparisons between intervention and control groups (p<0.05 and p<0.01, respectively). The changes of BMI and waist circumference from baseline to 12-week were also significant in post-hoc comparisons (p<0.05). After completion of the weight management program, there were significant differences on the subjective estimates such as physical component summary of SF-36, and total scores, psychosocial heath, physical health and diet of the KOQOL, and total scores of B-WISE-K between intervention and control group. These significant differences were found at 12-week of treatment in post-hoc comparisons (p<0.05, respectively). CONCLUSION: The weight reduction program was effective for weight loss in schizophrenic inpatients. In addition, it might improve the subjective estimates such as obesity-related quality of life and weight-related body image in schizophrenic inpatients.
