OBJECTIVE: Observational studies have shown inconsistent associations of loneliness or social isolation (SI) with ischemic heart disease (IHD), with unknown mediators. METHODS: Using data from genome-wide association studies of predominantly European ancestry, we performed a bidirectional two-sample Mendelian Randomization (MR) study to estimate causal effects of loneliness ( N = 487,647) and SI traits on IHD ( N = 184,305). SI traits included whether individuals lived alone, participated in various types of social activities, and how often they had contact with friends or family ( N = 459,830 to 461,369). A network MR study was conducted to evaluate the mediating roles of 20 candidate mediators, including metabolic, behavioral and psychological factors. RESULTS: Loneliness increased IHD risk ( OR= 2.129; 95% confidence interval [ CI]: 1.380 to 3.285), mediated by body fat percentage, waist-hip ratio, total cholesterol, and low-density lipoprotein cholesterol. For SI traits, only fewer social activities increased IHD risk ( OR= 1.815; 95% CI: 1.189 to 2.772), mediated by hypertension, high-density lipoprotein cholesterol, triglycerides, fasting insulin, and smoking cessation. No reverse causality of IHD with loneliness and SI was found. CONCLUSION These findings suggested more attention should be paid to individuals who feel lonely and have fewer social activities to prevent IHD, with several mediators as prioritized targets for intervention.

PURPOSE: As COVID-19 spreads globally and affects people's health, there are concerns that the pandemic and control policies may have psychological effects on young people (age from 17 to 35 years). This psychological impact might vary in different countries, and thus we compared the prevalence of self-reported psychological distress, loneliness and posttraumatic stress symptoms (PTSS) among young people in the United Kingdom (UK) and China at the beginning of the COVID-19 pandemic. METHODS: Data of this study came from two sources. One source was the first wave of COVID-19 study in Understanding Society, a special wave of the UK household longitudinal study, which provided the high-quality, national-wide representative panel data. The sample comprised 1054 young people. The other source was an online survey on the mental health of 1003 young people from Shanghai, a highly developed area in China. The questionnaire included questions on the prevalence of common mental disorders (cut-off score ≥ 4), loneliness and potential PTSS (cut-off ≥ 33). Univariable analyses were conducted to test the differences in the self-reported prevalence of psychological distress and loneliness between the two groups. Multivariable logistic regression analyses were run to explore the predictors of psychological distress and loneliness among all the young people from England and Shanghai. RESULTS: Among the samples with self-reported psychological distress, the UK sample accounted for 34.4% (n=1054) and the Chinese sample accounted for 14.1% (n=1003). The difference between the two groups was statistically significant (p < 0.001). Additionally, 57.1% of people in the UK and 46.7% in China reported that they sometimes or often felt lonely, of which the difference is statistically significant (p < 0.001). Regression analysis of the entire samples showed that nationality, gender, psychotherapy and loneliness were significant predictors of 12-item General Health Questionnaire scores, while the variables of age and living alone were not. Significant predictors of self-reported loneliness were the nationality, gender, age, living alone and psychotherapy. In China, 123 (12.3%) young people, 49 men (11.3%) and 74 women (13.0%), met the criteria of PTSS symptoms (cut-off scores ≥ 33). These scores were only collected in China. CONCLUSION This evidence suggests that mental health and loneliness reported by young people were lower in China than that in the UK during the studied period. More research is needed to understand these differences. If the differential negative psychological impacts are confirmed, country-specific measures of prevention and intervention should be adopted to improve the mental health of young people under the ongoing impact of the pandemic.

OBJECTIVES: The aim of this study was to investigate the relationship between internet addiction, smartphone addiction, and psychosocial factors. This study was designed to examine the vulnerability factors for internet and smartphone addiction. METHODS: The participants were 1041 children and adolescents in a small and medium-sized cities. All of the participants were evaluated in terms of their demographic characteristics and present use of the internet and smartphone, as well as using internet and smartphone addiction and other psychological scales. Statistical analyses were performed to compare the psychosocial factors between the high risk, potential risk, and general user groups of internet and smartphone addiction. RESULTS: The participants were classified into three groups, the high risk (N=33), potential risk (N=203), and general user (N=805) groups with regard to their internet and smartphone addiction level. There were statistical significantly differences between the groups in terms of the economic status of the family, academic performance, parents, use of internet and smartphone, loneliness, family cohesion, family adaptability, perceived social support, and peer relationship. CONCLUSION: These results suggest that the internet and smartphone addiction of children and adolescents is related to various psychosocial vulnerability factors.

PURPOSE: This study was a prospective longitudinal study to identify changes in quality of life in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). It was based on Roy's adaptation model. METHODS: The questionnaires were administered before HSCT, 30 and 100 days after HSCT. Of the 48 potentially eligible patients, 44 (91.7%) participated in the study and 40 (90.9%) completed the questionnaires at 100 days after HSCT. Multilevel analysis was applied to analyze changes in quality of life. RESULTS: Overall, quality of life showed a decreasing tendency from pre-HSCT to 100 days after HSCT. The adaptation level of participants was compensatory. Type of conditioning was the significant factor influencing quality of life before HSCT (beta00=79.92, p <.001; beta01= - 12.64, p <.001) and the change rate of quality of life (beta10= - 1.66, p =.020; beta11=2.88, p =.014). Symptom severity (beta20= - 1.81, p =.004), depression (beta30= - 0.58, p =.001), social dependency (beta40= - 0.35, p =.165), and loneliness (beta50= - 0.23, p =.065) had a negative effect on changes in quality of life. Symptom severity and depression were statistically significant factors influencing changes in quality of life. CONCLUSION: According to the results of this study, the development of nursing intervention is needed to improve quality of life in patients undergoing allogeneic hematopoietic stem cell transplantation in the early immune reconstruction period. The interventions should include programs to enhance coping capacity and programs to help control symptom severity and depression. Also these interventions need to be started from the beginning of HSCT and a multidisciplinary approach would be helpful.

OBJECTIVE: To investigate the family function among the bereaved in hard-hit areas 1 year after Wenchuan earthquake and to provide basic information for family reconstruction. METHODS: A cross-sectional study was used to survey 264 bereaved who were selected according to the criteria in hard-hit areas after Wenchuan earthquake. RESULTS: The scores of family care function of the bereaved in hard-hit areas after Wenchuan earthquake were 6.52±2.65. Fifty percent of the participants' family kept in good state. The scores of the bereaved family cohesion ranged from 28 to 83 (64.22±9.18), and the scores of family adaptability ranged from 21 to 62 (41.84±6.62). There was no significant difference in the score of family cohesion between the bereaved family and the non-bereaved family (P>0.05). But the score of the family adaptability of the bereaved family was significantly lower than that of the non-bereaved family (P<0.05). The bereaved family types were as follows: 22.0% balanced type, 53.8% middle type and 24.2% extreme type. In the 16 family types, the "intimate-rigid" (24.6%), "intimate-regular" (19.7%) and "disengaged-rigid" (19.3%) type ranked the top three. CONCLUSION The family care function of the bereaved in hard-hit areas after Wenchuan earthquake is damaged to different degrees. The main type of family is the middle type. The loss of relatives reduces the participant family adaptability. In the late intervention, we should help the bereaved improve and enhance family function, and promote family reconstruction of the bereaved.

OBJECTIVES: Cases of psychiatric disorders are reported with a review of literature on mental health problems in North Korean defectors in South Korea. METHODS: Four patients who were admitted to a psychiatric hospital with major depression, schizophrenia, bipolar affective disorder, or mixed disorder of conduct and emotions of adolescent were studied. RESULTS: The most common precipitating factor was the separation from close persons they had been dependent on. Defector-specific stress included unfamiliar culture of South Korea, lack of ability to adapt to South Korean society, uselessness of past education and professional skills, stress with regard to being identified or discriminated as a North Korean defector, and guilt feeling for leaving their family behind in North Korea. North Korean defector-specific clinical findings were noted; these included reluctance to expose themselves as North Koreans, negative emotional reaction to discrimination of South Korean neighbors, submissive and passive attitude, loneliness, anxiety for the future related to refugee status, and strong stigma related to psychiatry. CONCLUSION: This case report suggests that an individualized or tailored treatment that considers their unique psychosocial situation, which especially focuses on discrimination and social support, is needed for North Korean defectors with mental disorders.

OBJECTIVE: To explore the reliability and validity of the short-form of the UCLA loneliness scale (ULS-8) among Chinese rural community-dwelling elderly. METHODS: ULS-8 was used for 839 Chinese rural community-dwelling elderly during face-to-face interviews. RESULTS: After deleting item-3 (I am an outgoing person) and item-6 (I can find companionship when I want it), the exploratory factor analysis showed that the construction of the new scale (ULS-6) fit the original construction of ULS-8, a single-factor resolution. Cronbach's α coefficient of ULS-6 was 0.831. Test-retest reliability was 0.715. All item-total correlations reached statistical significance. The total score of ULS-6 was correlated to quality of life, social support, suicidal ideation, and current major depression episode. CONCLUSION ULS-6 shows satisfactory reliability and validity and meets the needs of psychometric properties, and can be used for the evaluation of loneliness among Chinese rural elderly.

PURPOSE: The purpose of this study was to identify the relationship of peer relationships, self-reported attachment security, perceived parental rearing attitudes, and loneliness in upper elementary school-age children. METHODS: The data were collected from 207 students in grades 5 or 6, and descriptive statistics, t-test, Pearson correlation coefficients and Stepwise multiple regression were used with the SPSS/PC 12.0 program to analyze the data. RESULTS: There was a significant difference in loneliness between the upper 25% and lower 25% groups of peer relationships, perceived parental rearing attitudes, and self-reported attachment security. Stepwise multiple regression analysis showed affection-hostility in parental rearing attitudes, validation and conflict in peer relationships, and attachment security explained 39.6% of the total variance in loneliness. CONCLUSION: These results may contribute to a better understanding of loneliness in upper elementary school-age children. The results of the present study indicate a need to develop nursing interventions to prevent and manage children's loneliness

PURPOSE: The purpose of this study was to collect basic data on social support and acculturative stress in migrant workers. METHODS: Between August, 2007 and January, 2008 171 immigrant workers completed data collection using a questionnaire. Workers were recruited from 2 churches, one in Seoul and the other in Gyeonggi Province. Mean and standard deviation, t-test, ANOVA, Pearson correlation coefficients and Stepwise multiple regression were used to analyze the data. RESULTS: The average score for social support was 3.73 (+/-0.65) and for acculturative stress, 2.52 (+/-0.65). There were significant differences acculturative stress according to gender (t=2.152, p=.033), kind of job (t=2.597, p=.040), and have community or not (t=2.899, p=.005). There was a significant negative correlation between social support and acculturative stress (r=-.270, p=.001). Factors influencing acculturative stress were existence of participants having a community of people from their home country or not (R2=.151, p=.002). CONCLUSION: More studies are needed to identify the variables that influence acculturative stress in immigrant workers.
