“…These methods are useful not only for studies of infectious diseases but also for studies of non-infectious diseases or events like suicide. Worldwide there have been several reports of suicide cluster analyses [14][15][16][17][18][19]. We performed spatial cluster analyses using several methods as well as examined related factors using the CAR model including spatial smoothing.…”

“…As for the application related to spatial epidemiology, there have been several reports of suicide cluster analyses worldwide [14][15][16][17][18][19]. Namely, a study in New South Wales, Australia, between 2005 and 2013 [14] demonstrated the importance of examining geographical variations in spatial clustering of fatal and non-fatal suicide attempts.…”

“…Namely, a study in New South Wales, Australia, between 2005 and 2013 [14] demonstrated the importance of examining geographical variations in spatial clustering of fatal and non-fatal suicide attempts. A study in Central Brazil during 2000-2010 [15] showed spatial-temporal trends and risk of suicide; a study in Sergipe, Brazil, [16] performed spatial analysis and detected temporal trends in suicide mortality for the period from 2000 to 2015; in Kentucky a spatial epidemiologic investigation. was performed from 1999 to 2008 [17]; and in Idaho in the US [18] spatial clustering of suicide and associated community characteristics for the period 2010 to 2014 were reported.…”

Background: Suicide mortality is high in Japan and early interventional strategies to solve that problem are needed. An accurate evaluation of the regional status of current suicide mortality would be useful for community interventions. A few studies in Kanagawa prefecture, located next to Tokyo and with the second largest population in Japan, have identified spatial clusters of suicide mortality at regional levels. This study examined spatial clustering and clustering over time of such events using spatial data from regional statistics on suicide deaths. Methods: Data were obtained from regional statistics (58 regions in Kanagawa prefecture) of the National Vital Statistics of Japan from 2011 to 2017. The standardized mortality ratio (SMR) and Empirical Bayes estimator for the SMR (EBSMR) were used as measures. Spatial clusters were examined by Kulldorff's circular spatial scan statistic, Tango-Takahashi's flexible spatial scan statistic and Tango's test. Linear regression and conditional autoregressive (CAR) models were used not only to adjust for covariates but also to estimate regional effects. The analyses were conducted for each year, inclusive. Results: Among male suicide deaths, being unemployed (50%) was most frequently related to suicide while among female health problem (50%) were frequent. Spatial clusters with significance detected by FlexScan, SatScan and Tango's test were few and varied somewhat according to the method used. Spatial clusters were detected in some regions including Kawasaki ward after adjustment by covariates. By the linear regression models, selected variables with significance were different between the sexes. For males, unemployment, family size, and proportion of higher education were detected for several of the years studied while for females, family size and divorce rate were detected over this period. These variables were also observed by the CAR model with 5 covariates. Regional effects were much clearer by considering the spatial parameter for both males and females and especially, Kawasaki ward was detected as a high risk region in many years. Conclusion: The present results detected some spatial clustering of suicide deaths within certain regions. Factors related to suicide deaths were also indicated. These results would provide important information in policy making for suicide prevention.

“…Analysing the maps of Indigenous homicide, we highlight its potentially high incidence in the state of Mato Grosso do Sul, more specifically the south of the state, with a possible epicentre in the municipality of Dourados. This area was also the focus of recent studies revealing high rates of Indigenous suicides 20,21 . Among 'Guarani Kaiowá' and 'Nhandeva' groups from Mato Grosso do Sul that live in this area, between 2000 and 2007, the mortality rate due to suicide was 118.4/100,000.…”

This study aimed to describe a panorama of Indigenous homicide in Brazil, analysing the main characteristics and territorial distribution between 2010 and 2014. Demographic study of Indigenous population data obtained from the Brazilian Institute of Geography and Statistics and Indigenous homicide data (2010-2014) from the Ministry of Health. Data were analysed using descriptive statistics, victims’ characteristics, type of homicides and geographical distribution, which were then plotted on maps using ArcGIS. Findings revealed: 1) a national estimated average of Indigenous homicide rate of 22.5 per 100,000 Indigenous inhabitants per year; 2) a map showing where homicides were registered and the mean homicide rates for Brazilian regions and states, with highest rates in Roraima and Mato Grosso do Sul; 3) the main homicide method were sharp or penetrating objects; 4) Indigenous male homicide rate was 2.4 times higher than female, but Indigenous female rate was more than double that of non-Indigenous; 5) high homicide rates of Indigenous children (under 1-year-old) in areas of the states of Roraima and Amazonas. We advise careful consideration of Indigenous cultural beliefs to avoid errors of judgement, reflecting how Indigenous populations are at risk of homicide in some areas.

“…The southern part of Mato Grosso do Sul is marked by land conflicts, commonly violent, between the indigenous population and the agricultural sector, the economic base of the state. [23][24][25][26][27] This violent oppression further aggravates the vulnerability of the indigenous population living there and may worsen their socioeconomic condition. In addition, the border with Paraguay is one of the main routes of entry of drugs in Brazil.…”

Indigenous people usually live in precarious conditions and suffer a disproportionally burden of tuberculosis in Brazil. To characterize the socioeconomic status of indigenous peoples with active tuberculosis in Brazil, this cross-sectional study included all Amerindians that started tuberculosis treatment between March 2011 and December 2012 in four municipalities of Mato Grosso do Sul state (Central-Western region). We tested the approach using principal components analysis (PCA) to create three socioeconomic indexes (SEI) using groups of variables: household characteristics, ownership of durable goods, and both. Cases were then classified into tertiles, with the 1 st tertile representing the most disadvantaged. A total of 166 indigenous cases of tuberculosis were included. 31.9% did not have durable goods. 25.9% had family bathroom, 9.0% piped water inside the house and 53.0% electricity, with higher proportions in Miranda and Aquidauana. Houses were predominantly made using natural materials in Amambai and Caarapó. Miranda and Aquidauana had more cases in the 3 rd tertile (92.3%) and Amambai, in the 1 st tertile (37.7%).The indexes showed similar results and consistency for socioeconomic characterization.The percentage of people in the 3 rd tertile increased with years of schooling. The majority in the 3 rd tertile received Bolsa Família, a social welfare programme. This study confirmed the applicability of the PCA using information on household characteristics and ownership of durable goods for socioeconomic characterization of indigenous groups and provided important evidence of the unfavorable living conditions of Amerindians with tuberculosis in Mato Grosso do Sul.
