Study on 900 people in order to determine the prevalence of depression disorder in Ho Chi Minh City (HCMC). Results: prevalence of depression disorder was 6.6%, similar to the percentage of 7.6% defined by WHO, and prevalence of recurrent depression was 22%. The prevalence of depression in HCMC with some environmental factors was 11.5% in separation/divorce status (lower than that in US), 8.7% in unemployed people (lower than the rate of 15.2% in US), and was 13.3% in low-income people (similar to in US). Depression disorder is a common and recurrent condition in HCMC as well as in other countries, but varies between many countries because the difference in social-economic development has influenced differently to this disorder.

Depression is a relatively common agonizing psychiatric disorder that affects the way we feel and think about ourselves and the world around us. Cognitive theories of depression have long posited that various cognitive biases are involved in the development and recurrence of depression. However, the current cognitive theory of depression has been reformulated and expanded from the previous cognitive model of depression based on the results from pharmacological, neuroimaging and neurocognitive studies. This review summarizes the evidence for cognitive dysfunctions in depression and the related pharmacological, neuroanatomical and genetic aspects which aim to integrate our knowledge about the cognitive aspects of depression and its treatment. The newly formulated cognitive theory of depression provides directions for future investigation to identify people at risk, to minimize recurrence, and to maximize long-term beneficial outcomes for those suffering from depression.

OBJECTIVES: It is an important reform for medical education in China to combine professional postgraduate training with standardized resident training. This study aims to evaluate the depression and perceived stress in postgraduate students of clinical medicine and residents from society and to determine the relation between depression and perceived stress in medical residents. METHODS: Chinese Perceived Stress Scale (CPSS) and Self-Rating Depression Scale (SDS) were applied to 330 residents (including 235 postgraduate students of clinical medicine and 95 residents from society) from a Class-A Grade-3 genernal hospital in Hunan Province to evaluate and compare the depression and perceived stress in postgraduate students of clinical medicine and residents from society. Pearson correlation analysis was performed to assess the association between depression and perceived stress. Stress resources between 2 groups of residents were observed and compared. RESULTS: Of the 235 postgraduate students of clinical medicine, 148 (63.0%) showed depression and 162 (68.9%) showed elevated perceived stress. Main stress resources were academic pressure, scientific research pressure, and employment pressure. Of the 95 residents from society, 52 (54.7%) showed depression and 58 (61.1%) showed elevated perceived stress. Main stress resources were economic stress, employment pressure, and academic pressure. The scores of CPSS and SDS were significantly higher in postgraduate students of clinical medicine than those in residents from society ( CONCLUSIONS Residents (including postgraduate students of clinical medicine and residents from society) possess depression and elevated perceived stress with positive correlation. The postgraduate students of clinical medicine show higher level of depression and perceived stress than the residents from society under the "unified double-track" training system.

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory disorder of the central nervous system predominantly targeting optic nerves and the spinal cord. The prevalence of the disease is much higher in Asia than in other parts of the world. Pain can be detected in more than 80% of NMOSD patients, with evoked pain mostly being caused by painful tonic muscle spasms and neuropathic pain as the most characteristic types. Depression is often comorbid with pain, and their comorbidity can severely influence quality of life. In recent years, studies have found considerable overlaps between the mechanisms of pain and depression; however, their association remains unclear. This article reviews the epidemiology, mechanism, evaluation and treatment of pain-depression comorbidity in NMOSD patients.

OBJECTIVETo investigate the relationship between body weight, body dissatisfaction and depression symptoms among Chinese children.

METHODSThe fasting body weight and height of the third and fourth grade students (n = 3886, aged 9 or 10 years) from 20 schools in Beijing, China, were measured, and the students were asked to choose the figures of body image and to complete the self-reported children's depression inventory (CDI) questionnaire.

RESULTSThe CDI Cronbach's alpha was 0.81. The total CDI score was 9.60 +/- 7.50, 13.2% of children (boys 16.7% vs girls 9.5%) were at risk of developing depression symptoms. Overweight girls, but not boys, had significantly higher total CDI score than their normal weight counteparts. Both obese girls and boys showed a higher negative self-esteem score. More than one fifth underweight girls still wanted to be thinner while more than one third obese boys still wanted to be heavier. Children who wanted to be thinner showed slightly higher scores of ineffectiveness and negative self-esteem. After introducing the body dissatisfaction into the model, overweight was still associated with total CDI score among girls and obesity was still associated with negative self-esteem among both boys and girls.

CONCLUSIONOverweight girls show a significantly higher depression symptom score than their normal weight counterparts, which maybe partially explained by body dissatisfaction. Obese boys and girls are both more likely to suffer from low self-esteem, which is partially explained by body dissatisfaction.

Anxiety, depression, and even suicidal ideation are becoming the most common mental health problems affecting Chinese college students. The present study investigated the prevalence of mental health problems and their predictors in a sample of 1048 Chinese college freshmen from Shanghai. We used following brief screening instruments to measure symptoms of anxiety and depression, as well as self-control and suicidal ideation: the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder scale (GAD-7), a mental health and mental health knowledge questionnaire (MK), a mental disease-related attitude questionnaire (MA), questionnaires about the knowledge of psychological services and utilities, the Mini International Neuropsychiatric Interview (MINI) Suicide module, the Self-Rated Health Measurement Scale (SFHMS), the Self-Esteem Scale (SES), the Simplified Coping Style Questionnaire (SCQ), and the Perceived Stress Scale-10 (PSS-10). Over half of the students suffered from at least one mental health problem. Approximately 65.55% of freshmen had depression, and 46.85% had anxiety. Minority status, low family income, and religious belief were significantly associated with current mental health problems. These findings indicate that mental disorders are highly prevalent among the freshman student population. The prevalence of such mental disorders was greater than that of the general population, and the majority of students with mental health problems require treatment.

BACKGROUNDCoronary heart diseases (CHD) have been identified as one of topmost diseases affecting the Chinese population. However, depression in CHD has not been reported and there are limited high quality empirical studies in China focused on the prevalence of the comorbidity. This study aimed to estimate the pooled prevalence of depression with CHD in China.

METHODSSystematic review and meta-analysis of published epidemiologic studies on the depression in CHD patients in China were conducted. The research findings dated before 30 September 2013 were obtained from Ovid Medline, EMBASE and two Chinese electronic publication libraries WANFANG and CNKI. We used "cardiovascular disease", "depression" and "China" as the search themes in Ovid Medline and EMBASE and "cardiovascular disease" and "depression" in WANFANG and CNKI. Random-effects meta-analysis was used to estimate the prevalence of depression in CHD patients.

RESULTSTwenty-seven studies were included in the review. Twenty-three studies had 5 236 participants who were hospitalized and four studies had 1 353 participants from community. The overall prevalence of depression in CHD from hospital was 51% (95% CI: 0.43, 0.58; I-squared = 97%, P = 0.000).The prevalence of depression in CHD from community ranged between 34.6% to 45.8%, and the severe depression was found ranging between 3.1% to 11.2%.

CONCLUSIONSOn comparing data with other countries, the prevalence of depression in CHD among admitted patients in China was found to be high. The physicians and healthcare providers should pay more attention to the "physical-mental" health of the CHD patients.

OBJECTIVE: To explore joint association of depression symptoms and 10-year risk of ischemic cardiovascular disease (CVD) in middle-aged and elderly people in China. METHODS: Based on China Health and Retirement Longitudinal Study(CHARLS)database using 2011 baseline data and the follow-up cohort data of 2013, 2015 and 2018, describe the distribution characteristics of baseline depressive symptoms and 10-year risk of ischemic cardiovascular disease in 2011. Cox survival analysis model was used to analyze the individual, independent and joint association of depression symptoms and 10-year risk of ischemic cardiovascular disease with cardiovascular disease. RESULTS: A total of 9 412 subjects were enrolled. The detection rate of depressive symptoms at baseline was 44.7%, and the 10-year middle and high risk of ischemic cardiovascular disease was 13.62%. During an average follow-up of 6.19 (6.19±1.66) years, 1 401 cases of cardiovascular disease were diagnosed in 58 258 person-years, revealing an overall incidence density of 24.048/1 000 person-years. After adjusting the factors, in terms of individual impact, the participants with depressive symptoms had a higher risk of developing CVD (HR=1.263, 95%CI: 1.133-1.408), while medium to high risk of ischemic cardiovascular disease had a higher risk of developing CVD (HR=1.892, 95%CI: 1.662-2.154). Among independent influences, participants with depressive symptoms had a higher risk of developing CVD (HR=1.269, 95% CI: 1.138-1.415), while medium to high risk of 10-year risk of ischemic cardiovascular disease had a higher risk of developing CVD (HR=1.898, 95%CI: 1.668-2.160). Joint impact result showed the incidence of cardiovascular disease in the low risk of 10-year risk of ischemic cardiovascular disease with depressive symptoms group, middle and high risk of 10-year risk of ischemic cardiovascular disease without depressive symptoms group, and 10-year middle and high risk of ischemic cardiovascular disease with depressive symptoms group were 1.390, 2.149, and 2.339 times higher than that of low risk of 10-year risk of ischemic cardiovascular disease without depressive symptoms (P < 0.001). CONCLUSION The superimposed depression symptoms of the middle and high-risk population at the 10-year risk of ischemic cardiovascular disease will aggravate the risk of cardiovascular disease in middle-aged and elderly people. In combination with the actual lifestyle intervention and physical index health management, attention should be paid to mental health intervention.

Objective: To understand the depression status and its influencing factors in elderly patients with MS in China and to explore the correlation between various components of elderly MS and depression. Methods: This study is based on the "Prevention and Intervention of Key Diseases in Elderly" project. We used a multi-stage stratified cluster random sampling method to complete 16 199 elderly aged 60 years and above in 16 counties (districts) in Liaoning, Henan, and Guangdong Provinces in 2019, excluding 1 001 missing variables. Finally, 15 198 valid samples were included for analysis. The respondents' MS disease was obtained through questionnaires and physical examinations, and the respondents' depression status within the past half month was assessed using the PHQ-9 Depression Screening Scale. The correlation between elderly MS and its components and depression and its influencing factors were analyzed by logistic regression. Results: A total of 15 198 elderly aged 60 years and above were included in this study, with the prevalence of MS at 10.84% and the detection rate of depressive symptoms in MS patients at 25.49%. The detection rates of depressive symptoms in patients with 0, 1, 2, 3, and 4 MS abnormal group scores were 14.56%, 15.17%, 18.01%, 25.21%, and 26.65%, respectively. The number of abnormal components of MS was positively correlated with the detection rate of depressive symptoms, and the difference between groups was statistically significant (P<0.05). The risk of depression symptoms in patients with MS, overweight/obesity, hypertension, diabetes, and dyslipidemia was 1.73 times (OR=1.73, 95%CI:1.51-1.97), 1.13 times (OR=1.13, 95%CI:1.03-1.24), 1.25 times (OR=1.25, 95%CI:1.14-1.38), 1.41 times (OR=1.41, 95%CI:1.24-1.60), 1.81 times (OR=1.81,95%CI:1.61-2.04), respectively, more than those without the disease. Multivariate logistic regression analysis showed that the detection rate of depressive symptoms in patients with sleep disorders was higher than that with normal sleep (OR=4.89, 95%CI: 3.79-6.32). The detection rate of depressive symptoms in patients with cognitive dysfunction was 2.12 times higher than that in the average population (OR=2.12, 95%CI: 1.56-2.89). The detection rate of depressive symptoms in patients with impaired instrumental activities of daily living (IADL) was 2.31 times (OR=2.31, 95%CI: 1.64-3.26) higher than that in the average population. Tea drinking (OR=0.73, 95%CI: 0.54-0.98) and physical exercise (OR=0.67, 95%CI: 0.49-0.90) seemed to be protective factors for depression in elderly MS patients (P<0.05). Conclusions: Older patients with MS and its component abnormalities have a higher risk of depression than the average population. Sleep disorders, cognitive impairment, and IADL impairment are important influencing factors for depression in elderly MS patients, while tea drinking and physical exercise may help to reduce the risk of the disease.
