Daily distribution of suicide attempts during cluster weeks in each season, shown separately for women
Article
The influence of weather on mood and mental health is commonly debated. Furthermore, studies concerning weather and suicidal behavior have given inconsistent results. Our aim was to see if daily weather changes associate with the number of suicide attempts in Finland. All suicide attempts treated in the hospitals in Helsinki, Finland, during two se...

Psychological factors associated with low social status have been proposed as one possible explanation for the socio-economic gradient in health. The aim of this study is to explore whether different indicators of psychological distress contribute to socio-economic differences in cause-specific mortality. The data source is a nationally representat...
Article
Background: Driving under the influence of drugs (DUID) is an increasing public health and traffic safety related problem. We examined the poly-drug findings and their trends among all apprehended DUID offenders in Finland. Methods: A register data from 1977 to 2007 was analysed. The data included a total of 31,963 suspected DUID cases with a posit...
Article
The aim of this study was to examine the overall and cause-specific mortality of DUI arrestees compared to a reference population with no history of DUI and to recognize the risk factors of premature death. The data used were a register of all DUI arrestees between April 1988 and December 2006. All drivers with drug-positive samples were excluded....
Article
Studying drugged drivers gives complementary information about mortality of drug users, which mainly has been studied among opioid abusers. The aim of this study was to analyse mortality rates and causes of death among drivers under the influence of drugs (DUID) in Finland and compare them with the general Finnish population during 1993-2006. Regis...
Article
Recidivism is a major problem in the prevention of DUI offenses. It is suggested that impairing substances used by drivers may relate to a higher risk of recidivism. This study aims to determine rearrest rates in different groups of arrested drivers focusing on different substances found in the blood. The data utilized were obtained from the regist...

The data cover all attempted suicides referred to healthcare in 1989 and 1997 in Helsinki, Finland. There are clear and persistent differenc...
Article
Adolescents in many countries show high rates of suicide attempts and repetitions of attempts as a common feature. Attempted suicide is the best predictor of future suicide. Repetition of attempts further increases the risk of suicide. The present study sought to identify patterns and risk factors for repetition of attempts in older teenagers. Data...

Previous studies have shown a positive association between unemployment and attempted suicide. This study investigated transitions of employment status among suicide attempters during the severe economic recession. The main research question was whether inequality in the labour market also prevails among as selected a population as suicide attempte...

Excessive mortality of suicide attempters has emerged from many follow-up studies. Completed suicide is the main cause of excess deaths, but the increased risk of deaths from other unnatural and natural causes is also of major public health concern. We lack follow-up studies of the different causes of death in cohorts of suicide attempters. The pre...

... The condition is often under diagnosed and frequently undertreated. 3 Major depressive disorder is a mental disorder common in psychiatric practice wherein a patient presents with at least one of the two major symptoms, constant sadness or anhedonia, accompanied by at least five of these nine secondary symptoms for at least two weeks. 4 Although depression can occur at any age, adults 18 to 29 years of age experience the highest rates of major depression during any given year. ...
... Taip pat tai gali padėti paaiškinti, kodėl pacientų, turinčių sutrikimų, susijusių su psichoaktyviųjų medžiagų vartojimu, šios skalės įverčiai nesiskyrė nuo norminės imties įverčių. Viena vertus, ankstesni tyrimai rodo, kad priklausomybę nuo alkoholio (kai depresija nėra komorbidinė diagnozė) turintys asmenys nepasižymi reikšmingai didesniais BHS įverčiais nei asmenys, kuriems ši priklausomybė nediagnozuota (Suominen et al., 1997), kita vertus, BHS yra itin jautri socialinio pageidaujamumo efektui . Kadangi rizikingai psichoaktyviąsias medžiagas vartojantys asmenys yra linkę į savo įvaizdžio valdymą ir yra jautrūs socia-linio pageidaujamumo efektui (Davis et al., 2010), tai galėjo nulemti mažesnius jų BHS skalės įverčius ir šiame tyrime. ...
... Some worldwide analyses of suicide trends and rates in the world have been published [12][13][14][15], but very little is known world-wide about the causes of death and suicide rates among young people aged 15 -19. International comparability of data is also discussed in these refences. ...
... Using the same sample, Jessen, et al. (1999b) found that attempted suicides peaked in the Spring only for females and on Sundays again for females, and in the late evening. The trends for time of day and day of week differ from those found for suicides. ...

... However, the terminological use of these elements has led to various inconsistencies and confusions. Especially when discussing non-lethal self-harm behaviors, the terms motive, cause, and intention have been used interchangeably and synonymously with the idea of achieving something or obtaining something desired in the future through the person's action (Hjelmeland & Ostamo, 1997). ...
... The research phase was integral to the overall planning, part of which involved a detailed psychological autopsy study of 1397 people who died by suicide, from which many publications have emerged. The breadth of the research can be gauged by the project plan outlined by Lonnqvist et al. (1995), which had three distinct areas of focus. The first was a series of studies on suicide per se, including suicide in adolescents and younger adults, in persons with schizophrenia or alcoholism, with physical illness, and in both psychiatric and in general hospitals, as well as an examination of different methods of suicide. ...
... 29,30 However, some uncertainty exists regarding the association of the in-school experience with suicidality patterns because similar peaks, typically in the spring, are also well documented across the adult life span. 13,18,[31][32][33][34][35][36] In this study, we hypothesized that the spring 2020 COVID-19-related school closures, which occurred uniformly across the US, would disrupt the seasonality of suicidality, deviating from the typical seasonal patterns. Specifically, we expected that the usual increase in suicidality during the spring months would not be observed during the school closures. ...
... Indeed, as many as 25% of drivers involved in non-fatal RCTs who report benzodiazepine use are also found to have measurable levels of alcohol in their system at the time of collision (23). Previous epidemiological studies examining the prevalence of drug consumption by drivers (23)(24)(25)(26)(27) have been primarily concerned with the number of drivers who have been involved in an RTC and/or apprehended under the suspicion of driving under the influence of drugs (DRUID). Whilst these studies clearly indicate that co-consumption of sedatives and alcohol drastically increases the likelihood of drivers being involved in an RTC, they potentially only represent the most extreme outcomes for drivers who are significantly impaired (e.g., accidents that result in hospitalization or death), and might not fully address the driving practises that lead to RTCs or the prevalence of driving whilst potentially impaired. ...
