Analysing effects of financial support for regional suicide prevention programmes on methods of suicide completion in Japan between 2009 and 2018 using governmental statistical data.

ABSTRACT:

Objectives

To explore the mechanisms of reduction of suicide mortality in Japan (from 25.7 to 16.5 per 100 000 population) between 2009 and 2018, the present study determined the effects of execution amounts of regional suicide prevention programmes (Emergency Fund to Enhance Community-Based Suicide Countermeasure: EFECBSC) on gender-specific trends of suicide mortality by disaggregated methods.

Design and setting

Stepwise multiple regression analysis was used to determine the effects of execution amounts of 10 subdivisions of execution amounts of financial support for regional suicide prevention programmes (EFECBSC) on suicide methods and gender disaggregated suicide mortalities in Japan between 2009 and 2018 using the statistical data obtained from national governmental database.

Results

The suicide mortalities by the most common/frequent suicide methods, hanging, charcoal burning and jumping were significantly decreased between 2009 and 2018. Male hanging suicide was decreased by prefectural enlightenment, municipal development programmes, but female hanging suicide was decreased by municipal personal consultation programmes. Municipal development and enlightenment programmes decreased male and female charcoal-burning suicide mortalities, respectively. Jumping suicide was decreased by prefectural telephone consultation programmes but was unexpectedly increased by municipal personal consultation and enlightenment programmes.

Conclusions

This study revealed the contribution of ECEFBSC on reduction of suicide mortalities, especially hanging, charcoal-burning and jumping suicides, via enhancement of regional suicide prevention programmes in Japan; however, notably, the 'means substitution' from parts of hanging and charcoal burning to jumping is probably generated by EFECBSC. Therefore, these findings provide important aspects for planning evidence-based and cost-effective regional suicide prevention programmes.

Project description:To improve and plan regional suicide prevention programmes that utilise more cost-effective governmental financial support compared with previous programmes, the present study determined the effects of the amount of financial support provided for regional suicide prevention programmes, such as the Emergency Fund to Enhance Community-Based Suicide Countermeasures (EFECBSC), on the trends of suicide mortalities caused by six major suicide motives between 2009 and 2018, using forward multiple regression analysis. The ranking order of motives for male suicide was health, economy, family, employment, romance and school (in that order), whereas the ranking order for females was health, family, economy, romance, employment and school. Male suicide mortality caused by economy-related motives was significantly/inversely related to prefectural intervention programmes, whereas mortality caused by health-related motives was also significantly/inversely related to prefectural intervention programmes, but significantly/positively related to prefectural personal consultation support programmes. Contrary to males, female suicide mortality caused by health-related motives was significantly/inversely related to the municipal development programmes of leaders/listeners, whereas mortality caused by family- and school-related motives was significantly/positively related to prefectural and municipal telephone consultation support programmes, respectively. Contrary to our expectations, school-aged female suicide mortality caused by school-related motives was significantly/positively related to prefectural personal consultation support, enlightenment and municipal telephone consultation support programmes. These results indicate that Japanese regional suicide prevention programmes probably affect the suppression of male suicide mortality. However, these programmes are possibly ineffective, or at least partially, have an adverse effect, in regard to the suicide mortalities of female and school-aged populations. Therefore, we should work to improve regional suicide prevention programmes, making them more cost-effective and targeted towards female and school-aged populations in the future.

Project description:ObjectivesTo analyse demographic, social and geographic predictors of incompliant attitudes towards prescription completion in the UK.MethodsTwo waves of the Eurobarometer survey (85.1 and 90.1) were analysed, with a final sample size of 2016. Using logistic regression, the best-fitting combination of a set of identified variables was specified. The regression output and the model-averaged importance of each variable were analysed.ResultsCompared with a median prevalence region, respondents in the Nomenclature of Territorial Units for Statistics (NUTS) 1 London (OR = 2.358, 95% CI = 1.100-5.398) and Scotland (OR = 2.418, 95% CI = 1.083-5.693) regions were most likely to report an incompliant attitude. Respondents who correctly answered questions about whether unnecessary use of antibiotics could make them ineffective in future (OR = 0.353, 95% CI = 0.230-0.544), whether antibiotics kill viruses (OR = 0.644, 95% CI = 0.450-0.919) and whether antibiotics treat colds (OR = 0.412, 95% CI = 0.287-0.591) were less likely to report incompliant attitudes. Conversely, respondents who correctly responded that antibiotics can cause side effects (OR = 1.419, 95% CI = 1.014-1.999) were more likely to report incompliant attitudes. There was some evidence of associations between political orientation and level of compliance. Uncooperative survey respondents (OR = 2.001, 95% CI = 1.108-3.526) were more likely to report incompliant attitudes.ConclusionsIncompliant attitudes towards antibiotic prescription compliance in the UK are associated with a variety of factors, including regional geographic variation in attitudes. Knowledge about antibiotics can relate to good stewardship attitudes, but concerns over side effects are associated with poor attitudes. Further research should examine the underlying attitudes and beliefs that political orientation may be a marker for in the context of antibiotic stewardship. Survey samples reliant on self-selection are likely to be biased towards good stewardship.

Project description:Non-typhoidal Salmonella enterica infections cause a high disease burden in the United States with an estimated 1.2 million illnesses annually. The state of Florida consistently has a relatively high incidence compared to other states in the United States. Nevertheless, studies regarding the epidemiology of nontyphoidal salmonellosis and its spatial and temporal patterns in Florida were rarely reported. We examined the spatial and temporal patterns of 62,947 salmonellosis cases reported to FL Health Charts between 2009 and 2018. Dominant serotypes circulating in Florida were also explored using whole genome sequencing (WGS) based serotype-prediction for 2,507 Salmonella isolates sequenced by the Florida Department of Health during 2017 and 2018. The representativeness of laboratory-sequenced isolates for reported cases was determined by regression modeling. The annual incidence rate of salmonellosis decreased from 36.0 per 100,000 population in 2009 to 27.8 per 100,000 in 2016, and gradually increased in 2017 and 2018. Increased use of culture-independent testing did not fully explain this increase. The highest incidence rate was observed in children, contributing 40.9% of total reported cases during this period. A seasonal pattern was observed with the incidence peaking in September and October, later than the national average pattern. Over these 10 years, the Northeast and Northwest regions of the state had higher reported incidence rates, while reported rates in the Southeast and South were gradually increasing over time. Serotypes were predicted based on WGS data in the EnteroBase platform. The top-five most prevalent serotypes in Florida during 2017-2018 were Enteritidis, Newport, Javiana, Sandiego and Braenderup. The highest percentage of isolates was from children under 5 years of age (41.4%), and stool (84.7%) was the major source of samples. A zero-inflated negative binomial regression model showed that the reported case number was a strong predictor for the number of lab-sequenced isolates in individual counties, and the geospatial distribution of sequenced isolates was not biased by other factors such as age group. The spatial and temporal patterns identified in this study along with the prevalence of different serotypes will be helpful for the development of efficient prevention and control strategies for salmonellosis in Florida.
