Therefore, this study was conducted identify the causalities underlying recently transformed Japan. Monthly numbers disaggregated by sex and social standing, political uncertainty indices, such as economic policy (EPU) government management instability (AENROP), were obtained Japanese databases. Interrupted time-series analysis performed analyze SMRs sex/social standing associated with three General Principles Suicide Prevention Policy (GPSPP) periods COVID-19 pandemic. Panel data vector autoregressive analyses investigate uncertainties SMRs. During first second GPSPPs (2009-2017), all decreased, whereas those unemployed females did not change. third GPSPP (2017-2022), decreasing trends attenuated compared previous periods. All female SMRs, except females, showed sharp increases synchronized pandemic outbreak. No male sharply increasing at males/females drastically later pandemic, while employed multiple-person/single-person household males increase during positively related AENROP EPU. Other EPU/AENROP.

Statistical analyses from Japan reported increasing suicides in 2020, first the world, proving severity of public health crisis during COVID-19 pandemic; however, so far, international have not been shown to be objectively at population level. Followed studies existence a substantial heterogeneity among subgroups and time-lag impacts. Against Japan, policymakers, psychiatrists personnel should prioritize improving suicide prevention programs following evidence-based policymaking. Understanding how/what factors relate pandemic what other shaped numbers since 2020 through well-controlled/fine-grained high-quality longitudinal/cross-sectional data individual, regional, national levels is important for identifying reasons recent trend. For this purpose, study examined statistics, statistical analysis methods, their interpretations. Recent suggest an increased risk females <50 years males <30 2020-2022. Notably, time-series revealed that adolescent began before pandemic, while working-age female sharply synchronously with outbreak. Causality social issues facing global psychosocial socioeconomic transformations are high-risk groups. Finally, report demonstrates importance providing appropriate support based on objective understanding individuals who suicide, without being bound by traditional established knowledges.

In Japan, suicides had consistently decreased before the COVID-19 pandemic (from 2009–2019), but conversely increased after outbreak 2020–2022). To identify features of fluctuations in standardized suicide mortality rates per 100,000 population (SMRP) disaggregated by gender (males/females) and age (10-year cohorts) from 2009–2022 were analyzed using interrupted time-series joinpoint regression analyses. Temporal causalities unemployment rate (CUR) duration reasons for seeking work to SMRP vector autoregressive modelling with Granger causality analysis. composed three patterns, such as positive discontinuity (increasing) synchronized outbreak, attenuations decreasing trends pandemic, turning increasing/unchanging outbreak.

Background The Japanese Government programme ‘General Principles of Suicide Prevention Policy' (GPSPP) contributed to decreasing suicide mortality rates (SMRs) before the COVID-19 pandemic, but they increased after pandemic. Aims To identify risk factors for youth and impact GPSPP on suicide. Method Annual numbers during 2007–2022 were obtained from government databases. SMRs student non-student youths analysed with a linear mixed-effects model. Interrupted time-series analysis was conducted investigate temporal relations between three periods 52 motives among high school, special vocational school university students. Multiple regression influence grade repetition SMRs. Results Non-student higher than School-related (worrying about future/underachievement), health-related (mainly mental illness) family-related (conflict parent severe verbal reprimands) major During first period (2007–2012), no decreased. second (2012–2017), increased, unchanged. In contrast, third (2017–2022), exception male students, all increased. Unexpectedly, long-term negatively associated Conclusions These findings suggest that GPSPP-supported programmes in schools partially prevention. suppress increasing SMRs, social/life support specialists should participate in-school services bolster social standing lives students who repeat grades or experience setbacks.

Globally, suicide mortality rates have decreased in this century; however, it has been reported that the decreasing trends of some subgroups were attenuated late 2010s. These tendencies are pronounced among adolescents. In study, temporal fluctuations age-standardized death rate (ASDR-suicide), crude (CMR-suicide), and percentage suicides per total deaths (PTD-suicide) adolescents (10–24 years) global high-income middle-income countries Western Pacific Region (WPR) from 1990 to 2019, as well fixed effects communication factors (penetration cellular telephones Internet) on ASDR-suicide/CMR-suicide/PTD-suicide adolescents, analyzed using WHO Mortality Database. The male ASDR-suicide decreased, those males females unchanged, while other groups (males WPR WPR) increased. adolescent was almost equivalent 1990s but higher than consistently differences widened over time. PTD-suicide both whereas increased markedly by >40% telephone Internet penetrations negatively positively related WPR, respectively.

To provide up-to-date statistics in this study determined temporal fluctuations of standardized (SMRs), disaggregated by sex and age, joinpoint regression analysis using government database, named “Basic Data on Suicide Region”. From January December 2023, three fluctuation patterns SMRs pertaining working age older adults were detected, such as attenuations decreasing trends around mid-2010s), a sharply increasing trend that coincided with outbreak, gradually during pandemic, but no changes at end pandemic. particular, working-age females concurrently whereas those males did not change. However, diminished mid-2010s, decreased. The indicated non-significant early 2022, was observed for females. contrast adults, adolescents already began increase mid-2010s also between periods These results suggest, contrary our expectations, impacts both limited regarding 2020. Therefore, when revising prevention programs post-COVID-19 era, it should be noted focusing pandemic-associated factors alone is sufficient.
