Objective To study the effect of renal disease on the standardized mortality ratio (SMR) and life expectancy of patients with systemic lupus erythematosus (SLE). Methods Patients whose diagnosis met ≥4 American College of Rheumatology criteria for SLE were longitudinally followed up from 1995 to 2011. The cumulative survival rate, SMR, and life expectancy were calculated, and the effect of renal involvement, histologic class of lupus nephritis, renal damage, and end-stage renal disease (ESRD) on these parameters was evaluated. Results Of the 694 SLE patients studied, 368 (53%) had renal disease, and the distribution of histologic classes (among 285 patients) was class I (1%), class II (6%), class III (19%), class IV (47%), class III/IV + class V (10%), and class V (16%). Renal damage was present in 79 patients (11%), and 24 (3%) developed ESRD. The age- and sex-adjusted hazard ratios (HRs) of mortality in SLE patients with renal disease, those with renal damage, and those with ESRD, as compared to those without, were 2.23 (95% confidence interval [95% CI] 1.29-3.85), 3.59 (95% CI 2.20-5.87), and 9.20 (95% CI 4.92-17.2), respectively. Proliferative lupus nephritis (adjusted HR 2.28, 95% CI 1.22-4.24), but not the pure membranous type (adjusted HR 1.09, 95% CI 0.38-3.14), was associated with a significant increase in mortality. The age- and sex-adjusted SMRs of SLE patients without renal involvement, those with lupus nephritis, those with proliferative nephritis, those with pure membranous nephritis, those with renal damage, and those with ESRD were 4.8 (95% CI 2.8-7.5), 9.0 (95% CI 6.7-11.9), 9.8 (95% CI 6.5-14.1), 6.1 (95% CI 2.0-14.1), 14.0 (95% CI 9.1-20.5), and 63.1 (95% CI 33.6-108.0), respectively. The life expectancy of SLE patients with renal disease and those with renal damage was reduced by 15.1 years and 23.7 years, respectively, compared to the general population. Conclusion The presence of renal disease, in particular proliferative nephritis causing renal insufficiency, significantly reduces the survival and life expectancy of SLE patients.

Background: Media guidelines for suicide reporting are available in many countries. However, to what extent the mass media comply with the guidelines is unknown. Few studies are available that investigate systematically whether the mass media reflect the epidemiological reality of suicide deaths in their articles. Methods: Based on the WHO media guidelines, this study investigated the characteristics of newspaper articles of suicides in three Chinese communities, namely Hong Kong, Taiwan and Guangzhou. Epidemiological comparisons were conducted to identify the age and gender differences between the suicide victims as reported in the newspapers and the official records of suicide deaths in all three places. Results: The results found that one media characteristic complied with the WHO media guidelines (ie, only about 2% of the articles were printed on the front page), but there were a number of instances of non-compliance (ie, only 4--14% provided sources for help-seeking and 27--90% printed with photos). The epidemiological comparisons revealed an over-representation of younger suicides and an under-representation of late-life suicides in the newspapers of all three places. Furthermore, female suicides were found to be under-reported in Taiwan and Guangzhou newspapers, but not in Hong Kong papers. Conclusion: Non-compliant suicide articles are prevalent in the newspapers of these three Chinese settings. The observed media misrepresentations may potentially mislead the public and the policy makers about the actual risk for suicide in some demographic groups. [ABSTRACT FROM AUTHOR]

A semivarying coefficient model for the monthly numbers of suicides in Hong Kong is developed and a new estimation procedure for estimating the parametric component is proposed. The estimators are examined in a small simulation study and fitted to monthly suicide data to estimate a nonparametric long-term trend and parametric seasonal and socioeconomic effects. Fitting the model detected interpretable structure in the data that is consistent with that driving public health policy. While exploratory, the analysis motivates the collection of more detailed data and the development of more sophisticated models to help determine target groups and strategies to reduce the suicide rate in Hong Kong.

Background: There has been a marked rise in suicide by charcoal burning (CB) in some East Asian countries but little is known about its incidence in mainland China. We examined media-reported CB suicides and the availability of online information about the method in mainland China. Methods: We extracted and analyzed data for i) the characteristics and trends of fatal and nonfatal CB suicides reported by mainland Chinese newspapers (1998–2014); ii) trends and geographic variations in online searches using keywords relating to CB suicide (2011–2014); and iii) the content of Internet search results. Results: 109 CB suicide attempts (89 fatal and 20 nonfatal) were reported by newspapers in 13 out of the 31 provinces or provincial-level-municipalities in mainland China. There were increasing trends in the incidence of reported CB suicides and in online searches using CB-related keywords. The province-level search intensities were correlated with CB suicide rates (Spearman’s correlation coefficient = 0.43 [95% confidence interval: 0.08–0.68]). Two-thirds of the web links retrieved using the search engine contained detailed information about the CB suicide method, of which 15% showed pro-suicide attitudes, and the majority (86%) did not encourage people to seek help. Limitations: The incidence of CB suicide was based on newspaper reports and likely to be underestimated. Conclusions: Mental health and suicide prevention professionals in mainland China should be alert to the increased use of this highly lethal suicide method. Better surveillance and intervention strategies need to be developed and implemented. [ABSTRACT FROM AUTHOR]

Background: A surge in suicide rates in middle age people in Hong Kong and many Asian countries was recently observed. However, there is a paucity of suicide research on this subgroup of people in Asia. Methods: The next-of-kin of 85 suicide cases and 85 community subjects aged 30-49 years were interviewed by a psychological autopsy approach. Information was triangulated by interview notes, coroner's court files, and police investigation reports. Results: A multiple logistic regression analysis identified the following risk factors for suicide among the middle age people in Hong Kong: the presence of at least one psychiatric disorder (OR = 37.5, 95% CI 11.5-121.9, p < 0.001), indebtedness (OR = 9.4, 95% CI 2.2-40.8, p < 0.01), unemployment (OR = 4.8, 95% CI 1.3-17.5, p < 0.05), never married (OR = 4.2, 95% CI 1.1-16.3, p < 0.05), and lived alone (OR = 3.9, 95% CI 1.2-13.4, p < 0.05). Conclusion: The data show that socio-economical factors had a strong impact on suicide in the target group. Further research is needed to explore any positive qualities that protect the middleaged from suicide. The prevention of suicide in the middle-aged requires multiple strategies.

Background: The decreasing suicide rate in China has been regarded as a major contributor to the decline of global suicide rate in the past decade. However, previous estimations on China's suicide rates might not be accurate, since often they were based on the data from the Ministry of Health's Vital Registration ("MOH-VR") System, which is biased towards the better-off population. This study aims to compare suicide data extracted from the MOH-VR System with a more representative mortality surveillance system, namely the Center for Disease Control and Prevention's Disease Surveillance Points ("CDC-DSP") System, and update China's national and subnational suicide rates in the period of 2004-2014.Methods: The CDC-DSP data are obtained from the National Cause-of-Death Surveillance Dataset (2004-2014) and the MOH-VR data are from the Chinese Health Statistics Yearbooks (2005-2012) and the China Health and Family Planning Statistics Yearbooks (2013-2015). First, a negative binomial regression model was used to test the associations between the source of data (CDC-DSP/MOH-VR) and suicide rates in 2004-2014. Joinpoint regression analyses and Kitagawa's decomposition method are then applied to analyze the trends of the crude suicide rates.Results: Both systems indicated China's suicide rates decreased over the study period. However, before the two systems merged in 2013, the CDC-DSP System reported significantly higher national suicide rates (IRR = 1.18, 95% Confidence Interval [CI]: 1.13-1.24) and rural suicide rates (IRR = 1.29, 95% CI: 1.21-1.38) than the MOH-VR System. The CDC-DSP System also showed significant reversing points in 2011 (95% CI: 2006-2012) and 2006 (95% CI: 2006-2008) on the rural and urban suicide trends. Moreover, the suicide rates in the east and central urban regions were reversed in 2011 and 2008.Conclusions: The biased MOH-VR System underestimated China's national and rural suicide rates. Although not widely appreciated in the field of suicide research, the CDC-DSP System provides more accurate estimations on China's suicide rates and is recommended for future studies to monitor the reversing trends of suicide rates in China's more developed areas.
