OBJECTIVE: We aimed to explore the association between obesity and depression and the role of systemic inflammation in older adults. METHODS: Adults ≥ 65 years old ( n = 1,973) were interviewed at baseline in 2018 and 1,459 were followed up in 2021. General and abdominal obesity were assessed, and serum C-reactive protein (CRP) levels were measured at baseline. Depression status was assessed at baseline and at follow-up. Logistic regression was used to analyze the relationship between obesity and the incidence of depression and worsening of depressive symptoms, as well as the relationship between obesity and CRP levels. The associations of CRP levels with the geriatric depression scale, as well as with its three dimensions, were investigated using multiple linear regressions. RESULTS: General obesity was associated with worsening depression symptoms and incident depression, with an odds ratio ( OR) [95% confidence interval ( CI)] of 1.53 (1.13-2.12) and 1.80 (1.23-2.63), especially among old male subjects, with OR (95% CI) of 2.12 (1.25-3.58) and 2.24 (1.22-4.11), respectively; however, no significant relationship was observed between abdominal obesity and depression. In addition, general obesity was associated with high levels of CRP, with OR (95% CI) of 2.58 (1.75-3.81), especially in subjects free of depression at baseline, with OR (95% CI) of 3.15 (1.97-5.04), and CRP levels were positively correlated with a score of specific dimension (life satisfaction) of depression, P < 0.05. CONCLUSION General obesity, rather than abdominal obesity, was associated with worsening depressive symptoms and incident depression, which can be partly explained by the systemic inflammatory response, and the impact of obesity on depression should be taken more seriously in the older male population.

This study aimed to explore the prevalence and risk factors of cardiovascular disease (CVD) and psychological distress among female scientists and technicians in China. Accordingly, we included scientists and technicians from representative research institutions, medical institutions, colleges, universities, and businesses in China, and the data were collected from July 1, 2019 to March 31, 2021 via online questionnaires. The parameters evaluated in this study included age, sex, marital status, educational background, monthly income, sleep hours, sleep problems, smoking, alcohol consumption, work-related stress, work burnout, cardiovascular symptoms, CVD, family history, and depressive and anxiety symptoms. A total of 14 530 scientists and technicians were included, comprising 7144 men and 7386 women. We found 34.9% men and 16.6% women with CVD, 35.1% men and 21.4% women with depressive symptoms, 28.7% men and 13.8% women with anxiety symptoms, and 22.0% men and 9.5% women with CVD combined with depressive or anxiety symptoms. This study focused on the details of women. Younger women (age≤35 years) had the highest prevalence of depressive symptoms (24.9%), anxiety symptoms (16.2%), and comorbidity (11.2%). It was established that, despite traditional risk factors, unmanageable work burnout, depressive symptoms, and anxiety symptoms were associated with a higher risk of CVD in women; insomnia, overwhelming work stress, unmanageable work burnout, and CVD were linked to a higher risk of depressive symptoms and anxiety; insomnia, overwhelming work stress, and unmanageable work burnout were related to CVD combined with depressive or anxiety symptoms. A bidirectional relationship was noted between CVD and depression or anxiety in female scientists and technicians, and insomnia and overwhelming work stress were positively associated with comorbidity. It is suggested that effective measures should be taken to protect female scientists and technicians from CVD and psychological distress.

INTRODUCTION: Erectile dysfunction (ED) is a serious global burden that affects men as well as their partners. This study aimed to determine the prevalence and predictors of ED among male outpatient clinic attendees in Johor, Malaysia. METHODS: We conducted a cross-sectional study of Malaysian men aged ≥ 18 years attending two major outpatient clinics in Johor Bahru and Segamat in Johor, Malaysia, between 1 January 2016 and 31 March 2016. Subjects were chosen via simple random sampling and 400 patients were recruited. The study instrument was a survey form that consisted of three sections: sociodemographic and comorbid profile, validated English and Malay versions of the 15-item International Index of Erectile Function, and the 21-item Depression Anxiety Stress Scale. RESULTS: The overall prevalence of self-reported ED was 81.5%. The prevalence of ED according to severity was as follows: mild (17.0%), mild to moderate (23.8%), moderate (11.3%) and severe (29.5%). Multivariate analysis showed that ED was associated with increasing age (odds ratio [OR] 4.023, 95% confidence interval [CI] 1.633-9.913), Indian as compared to Malay ethnicity (OR 3.252, 95% CI 1.280-8.262), secondary as compared to tertiary education (OR 2.171, 95% CI 1.203-3.919), single as compared to married status (OR 6.119, 95% CI 2.542-14.734) and stress (OR 4.259, 95% CI 1.793-10.114). CONCLUSION ED has significant prevalence and severity among adult male outpatient clinic attendees in Johor. Increasing age, Indian ethnicity, lower educational level, singlehood and stress were significant predictors of ED.

Type 2 diabetes (T2D) has been associated with a high prevalence of depression.We aimed to determine the causal relation by performing a Mendelian randomization (MR) study using 34 T2D risk genetic variants validated in East Asians as the instrumental variable (IV). An MR analysis was performed involving 11 506 participants from a large longitudinal study. The T2D genetic risk score (GRS) was built using the 34 typical T2D common variants. We used T2D_GRS as the IV estimator and performed inverse-variance weighted (IVW) and Egger MR analysis. The T2D_GRS was found to be associated with depression with an OR of 1.21 (95% CI: 1.07-1.37) after adjustments for age, sex, body mass index, current smoking and drinking, physical activity, education, and marital status. Using T2D_GRS as the IV, we similarly found a causal relationship between genetically determined T2D and depression (OR: 1.84, 95% CI: 1.25-2.70). Though we found no association between the combined effect of the genetic IVs for T2D and depression with EggerMR(OR: 0.95, 95%CI: 0.42-2.14), we found an association for T2D and depression with IVW (OR: 1.75, 95% CI: 1.31-2.46) after excluding pleiotropic SNPs. Overall, the MR analyses provide evidence inferring a potential causal relationship between T2D and depression.

The Korea Chronic Obstructive Pulmonary Disorders Subgroup Study Team (Korea COPD Subgroup Study team, KOCOSS) is a multicenter observational study that includes 956 patients (mean age 69.9 ± 7.8 years) who were enrolled from 45 tertiary and university-affiliated hospitals from December 2011 to October 2014. The initial evaluation for all patients included pulmonary function tests (PFT), 6-minute walk distance (6MWD), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and the COPD-specific version of St. George's Respiratory Questionnaire (SGRQ-C). Here, we report the comparison of baseline characteristics between patients with early- (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stage I and II/groups A and B) and late-stage COPD (GOLD stage III and IV/groups C and D). Among all patients, the mean post-bronchodilator FEV1 was 55.8% ± 16.7% of the predicted value, and most of the patients were in GOLD stage II (520, 56.9%) and group B (399, 42.0%). The number of exacerbations during one year prior to the first visit was significantly lower in patients with early COPD (0.4 vs. 0.9/0.1 vs. 1.2), as were the CAT score (13.9 vs. 18.3/13.5 vs. 18.1), mMRC (1.4 vs. 2.0/1.3 vs.1.9), and SGRQ-C total score (30.4 vs. 42.9/29.1 vs. 42.6) compared to late-stage COPD (all P < 0.001). Common comorbidities among all patients were hypertension (323, 37.7%), diabetes mellitus (139, 14.8%), and depression (207, 23.6%). The data from patients with early COPD will provide important information towards early detection, proper initial management, and design of future studies.

OBJECTIVETo investigate the association between autism and prenatal environmental risk factors.

METHODSA case-control study was conducted among 193 children with autism from the special educational schools and 733 typical development controls matched by age and gender by using questionnaire in Tianjin from 2007 to 2012. Statistical analysis included quick unbiased efficient statistical tree (QUEST) and logistic regression in SPSS 20.0.

RESULTSThere were four predictors by QUEST and the logistic regression analysis, maternal air conditioner use during pregnancy (OR=0.316, 95% CI: 0.215-0.463) was the single first-level node (χ²=50.994, P=0.000); newborn complications (OR=4.277, 95% CI: 2.314-7.908) and paternal consumption of freshwater fish (OR=0.383, 95% CI: 0.256-0.573) were second-layer predictors (χ²=45.248, P=0.000; χ²=24.212, P=0.000); and maternal depression (OR=4.822, 95% CI: 3.047-7.631) was the single third-level predictor (χ²=23.835, P=0.000). The prediction accuracy of the tree was 89.2%.

CONCLUSIONThe air conditioner use during pregnancy and paternal freshwater fish diet might be beneficial for the prevention of autism, while newborn complications and maternal depression might be the risk factors.

BACKGROUND/AIMS: To estimate the prevalence and evaluate the associated psychological factors of functional gastrointestinal disorders (FGIDs) in males in their twenties who are currently enrolled in military service. METHODS: A total of 1,073 men in the Korean army were asked to complete questionnaires based on the Rome III criteria and Symptom Checklist-90-revised (SCL-90R). The prevalence of FGIDs was estimated, and the associated psychological factors were evaluated. RESULTS: A total of 967 men participated. The total prevalence of FGIDs was 18.5% (age-adjusted prevalence, 18.1%; 95% confidence interval [CI], 15.3% to 20.8%). The total SCL-90R scores were higher in men with FGIDs than men without FGIDs (24 [interquartile range, 13 to 44] vs 13 [5 to 28], p<0.001) and higher in men with overlapping syndromes than in those with single FGIDs (31 [18 to 57] vs 14 [5.75 to 29], p<0.001). Somatization (odds ratio [OR], 1.141; 95% CI, 1.09 to 1.20; p<0.001), obsessive-compulsive behaviors (OR, 1.084; 95% CI, 1.03 to 1.14; p=0.002) and depression (OR, 0.943; 95% CI, 0.90 to 0.99; p=0.020) were identified as independent predictive factors for FGIDs. CONCLUSIONS: FGIDs are common among men in their twenties who are fulfilling their military duty. Somatization and obsessive-compulsive features from the tense atmosphere are associated with the development or progression of FGIDs. Patients who exhibit overlapping syndromes require greater attention given their more severe psychopathology.

We investigated the frequency of sleep disturbances and the association between sleep disturbances and glucoregulation in type 2 diabetic patients. The frequency of sleep disturbances in 614 type 2 diabetic patients was investigated using validated sleep questionnaires. There were 381 male and 233 female patients. The mean age was 59.7 +/- 11.1 yr; the mean body mass index was 24.9 +/- 4.4 kg/m2; the mean HbA1c was 7.8% +/- 1.5%; and the mean duration of diabetes was 10.3 +/- 8.4 yr. The questionnaires revealed insomnia in 48.2% of the patients while 8.5% reported excessive daytime sleepiness. A total of 49% of the patients was poor sleepers, while 28.5% had depression. Multivariate logistic regression analysis showed that there was no significant association between HbA1c and other sleep disturbances, such as poor sleep, insomnia, and short duration of sleep. Sleep disturbances were very common in patients with type 2 diabetes mellitus, whereas there was no association between poor or short sleep and glucoregulation. Awareness and identifying sleep complaints in such patients are necessary to improve their quality of daily life.

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.

OBJECTIVETo study the mental health status of infertility patients with varicocele and its relationship with infertility.

METHODSUsing Hospital Anxiety and Depression scale (HAD), we assessed the psychological status of 110 infertility patients with varicocele, identified the risk factors of anxiety and depression in these patients, and analyzed the correlation among psychological and other relevant factors. Meanwhile, we recruited 61 age-matched normal fertile men as controls for comparative analysis. We also conducted logistic regression analysis on the mental health status of the 106 infertility patients with varicocele.

RESULTSThe prevalence rates of anxiety were 61.32% and 13.79%, while those of depression 37.73% and 6.90% in the infertile patients and normal fertile controls, respectively, significantly higher in the former than in the latter (P < 0.05). Logistic regression analysis showed that the main risk factors of anxiety and depression of the infertile patients were the number of times they sought medical care and the severity of their testis disorders.

CONCLUSIONInfertility patients with varicocele have psychological disorders, which are particularly associated with the frequency of the patients' clinic visit and the severity of their testis disorders.
