BACKGROUND: Korea's population is aging rapidly. Aged people who lead a solitary life are in a state of social isolation and face a greater risk of lower quality of life. The purpose of this study was to analyze the health behaviors and lifestyle patterns of aged people who lead a solitary life in Korea.METHODS: We analyzed 4,471 subjects (1,933 men and 2,538 women)-aged people aged 65 or above-based on data from the Korea National Health and Nutrition Examination Survey VI (2013–2015). The odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed using multivariate logistic regression analysis adjusted with age, household income level, occupational status, and geographical region.RESULTS: Socioeconomic status was lower in aged people who lead a solitary life than in those living with family. The ORs for frequent eating out alone (OR=2.93; 95% CI 1.83–4.38), daily eating out alone (OR=2.40; 95% CI 1.25–4.60), smoking (OR=1.57; 95% CI 1.06–2.32), feeling sick or uncomfortable (OR=1.59; 95% CI 1.08–2.36), feeling depressed (OR=4.10; 95% CI 2.53–6.65), and suicide ideation (OR=2.06; 95% CI 1.21–3.51) were significantly higher in male subjects who lead a solitary life. The ORs for frequent eating out alone (OR=1.57; 95% CI 1.10–2.24) and inadequate sleep duration (OR=1.29; 95% CI 1.03–1.61) were significantly higher in female subjects who lead a solitary life.CONCLUSION: Aged people who lead a solitary life exhibited unhealthy behaviors and poor mental health. The elderly men who lead a solitary life faced higher risk of poor health than the women. Integrated management of lifestyle behaviors is required to improve the quality of health in aged people who lead a solitary life.

social isolation in an urban community in Seoul.METHODS: A total of 704 adults who is not relying on long term care services and with age over 65 years were recruited from an urban community in Seoul. Subjects were evaluated by Korean version of Geriatric Depression Scale, short form, Mini Mental Status Examination, in the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease assessment battery, Korean version of Cut Down, Annoyed, Guilty and Eye Opener questionnaire, and Korean version of Mini-International Neuropsychiatric Inventory. Prevalence of depression and suicidal ideation, according to living-alone status were obtained, and risk factors affecting depression were evaluated.RESULTS: The prevalence for depressive disorder were 10.7% in overall, while prevalence for those not living alone 10.0% and for those living alone, 13.4%. From logistic regression models, the most important risk factor for depressive disorder was history of past mental health problems. Living alone failed to achieve significance as a risk factor of depressive disorder and social isolation predicted depressive disorder only when not accounting history of past mental health problems.CONCLUSION: Intrinsic personal vulnerability represented by history of past mental health problems were more important risk factor of depressive disorder than current social situations including living alone or social isolations.]]>

OBJECTIVE: This study aims to investigate differences between the elderly living alone and those living with others in frustrated interpersonal needs and life satisfaction. Also, we explore the effects of frustrated interpersonal needs on life satisfaction in the elderly living alone. METHODS: The participants include 572 elderly people aged over 60 in Busan, Korea. Life satisfaction were evaluated by the Life Satisfaction Self-Rating Scale (LSRS) and frustrated interpersonal needs were measured by the Interpersonal Needs Questionnaire-Revised (INQ-R). RESULTS: The overall LSRS scores were significantly lower in the elderly living alone (106.2±20.1) than living with others (115.3±13.9, p<0.001). The total INQ-R score was significantly lower in the elderly living alone (73.8±12.1) than those living with others (76.9±12.0, p<0.05). As a result of multiple regression analysis, we came to know that frustrated interpersonal needs were factors affecting life satisfaction in living alone group. CONCLUSION: The results of present study suggest that the elderly living alone are more likely to have poor life satisfaction and frustrated interpersonal needs. Also, frustrated interpersonal needs are related to life satisfaction. Thus, it is necessary to establish the social support system such as social isolation prevention and interpersonal relationship development.

OBJECTIVE: Post weanling isolation-reared (IR) rats are featured with depressive phenotype, yet its mechanism is not clearly defined particularly in terms of the involvement of central 5-HT1A receptors. The present study aims to examine the effects of 5HT1A activation on forced swim test (FST) in IR rats following 5-HT depletion. METHODS: Social control (SOC) and IR rats received an intracerebraoventricular (ICV) injection of 5-HT depletion agent, 5,7-DHT. 14 days after the surgery, rats were assessed their performance in FST with or without the challenge with a 5-HT1A agonist, 8-OH-DPAT. Rats were then sacrificed for analyzing their 5-HT tissue levels and the expressions of their 5-HA1A receptors in prefrontal cortex (PFC), hippocampus (HPX), and amygdala (AMY). RESULTS: 5,7-DHT decreased the tissue concentration of 5-HT in both IR and SOC rats. IR rats were more immobile and less sensitive to the lesion-induced immobility, however this effect was reversed by acute challenge of 8-OH-DPAT. 5,7-DHT lesion increased the expression of PFC 5-HT1A receptors. CONCLUSION: The integrity of central 5-HT system is developmentally crucial for the 5-HT1A-relevant depression profile in rats of social isolation.

OBJECTIVES: The US ranks ninth in obesity in the world, and approximately 7% of US adults experience major depressive disorder. Social isolation due to the stigma attached to obesity might trigger depression. METHODS: This paper examined the impact of obesity on depression. To overcome the endogeneity problem, we constructed pseudo-panel data using the Behavioral Risk Factor Surveillance System from 1997 to 2008. RESULTS: The results were robust, and body mass index (BMI) was found to have a positive effect on depression days and the percentage of depressed individuals in the population. CONCLUSIONS: We attempted to overcome the endogeneity problem by using a pseudo-panel approach and found that increases in the BMI increased depression days (or being depressed) to a statistically significant extent, with a large effect size.

OBJECTIVES: The purpose of this study was to examine psychological characteristics of patients who visited psychiatric clinic for medical certificate for military service using MMPI-2-RF. We compared target group with general psychiatric patients with same age range. METHODS: A total of 165 male patients for medical certificate and 154 general psychiatric patients were collected from the Department of Psychiatry of three university hospitals. There were significant differences of age and educational level between two groups. We used independent t-test, ANCOVA, χ² test to examine differences between two groups. RESULTS: Medical certificate group scored higher on the validity scales, the Higher-Order(H-O) scales, the Restructured Clinical(RC) Scales, the Specific Problems(SP) Scales, and the Personality Psychopathology Five (PSY-5) Scales. Especially, EID, RC7, HLP, SFD, SAV, SHY, DSF, and INTR-r showed significant differences between two groups on all three statistical tests. CONCLUSIONS: The present study showed that psychiatric patients who received psychological evaluation for military service have significantly higher emotional distress, helplessness, lower self-confidence, and lower quality of interpersonal relationships. And the difference of validity scales between two groups could be related with psychological burden of compulsory military service in the study sample which causes elevation on scales of infrequent responses. MMPI-2-RF would be helpful instrument to assess these emotional and psychological characteristics.

OBJECTIVES: By the end of the 2000s, the economic situation in many European countries started to deteriorate, generating financial uncertainty, social insecurity and worse health status. The aim of the present study was to investigate how the recent financial crisis has affected the lifestyle health determinants and behaviours of older adults living in the Mediterranean islands. METHODS: From 2005 to 2015, a population-based, multi-stage convenience sampling method was used to voluntarily enrol 2749 older adults (50% men) from 20 Mediterranean islands and the rural area of the Mani peninsula. Lifestyle status was evaluated as the cumulative score of four components (range, 0 to 6), that is, smoking habits, diet quality (MedDietScore), depression status (Geriatric Depression Scale) and physical activity. RESULTS: Older Mediterranean people enrolled in the study from 2009 onwards showed social isolation and increased smoking, were more prone to depressive symptoms, and adopted less healthy dietary habits, as compared to their counterparts participating earlier in the study (p<0.05), irrespective of age, gender, several clinical characteristics, or socioeconomic status of the participants (an almost 50% adjusted increase in the lifestyle score from before 2009 to after 2009, p<0.001). CONCLUSIONS: A shift towards less healthy behaviours was noticeable after the economic crisis had commenced. Public health interventions should focus on older adults, particularly of lower socioeconomic levels, in order to effectively reduce the burden of cardiometabolic disease at the population level.

OBJECTIVES: This study was performed to build the predictive model of suicidal ideation of elderly men living alone. METHODS: As for the subject, 251 subjects suitable for the selection criteria were selected among elderly men living alone above 65 years old in one region in Gyeongnam and three regions in Gyeongbuk. The data were collected via questionnaires and analyzed using SPSS version 20.0 and Amos version 18.0. RESULTS: The goodness-of-fit test result of hypothetical model were suitable for recommended level: χ²/df=1.47, RMR=.04, GFI=.92, AGFI=.90, CFI=.95, IFI=.95, RMSEA=.04. Self-esteem, individual coping, family cohesion, social support, social activity, and depression explained 55% of the model of suicidal ideation. The most influential direct factor of suicidal ideation was self-esteem, and social isolation was the most influential indirect influence on suicidal ideation. CONCLUSION: To sum up the above results, if we promote the researched variables of self-esteem, family cohesion, social activity, individual coping and social support in addition to developing and utilizing an efficient customized suicidal prevention nursing intervention program thereby reducing depression and social isolation, suicidal ideation of elderly men living alone would be prevented.

Proximal junctional kyphosis (PJK) is a common radiographic finding after long spinal fusion. A number of studies on the causes, risk factors, prevention, and treatment of PJK have been conducted. However, no clear definition of PJK has been established. In this paper, we aimed to clarify the diagnosis, prevention, and treatment of PJK by reviewing relevant papers that have been published to date. A literature search was conducted on PubMed using "proximal junctional", "proximal junctional kyphosis", and "proximal junctional failure" as search keywords. Only studies that were published in English were included in this study. The incidence of PJK ranges from 5% to 46%, and it has been reported that 66% of cases occur 3 months after surgery and approximately 80% occur within 18 months. A number of studies have reported that there is no significantly different clinical outcome between PJK patients and non-PJK patients. One study showed that PJK patients expressed more pain than non-PJK patients. However, recent studies focused on proximal junctional failure (PJF), which is accepted as a severe form of PJK. PJF showed significant adverse impact in clinical aspect such as pain, neurologic deficit, ambulatory difficulties, and social isolation. Numerous previous studies have identified various risk factors and reported on the treatment and prevention of PJK. Based on these studies, we determined the clinical significance and impact of PJK. In addition, it is important to find a strategic approach to the proper treatment of PJK.
