“…Cold and dark winter months, as well as semiannual and annual marks, may be the cause of high incidence of suicide attempts in these period [7]. Our findings indicate that the rate of suicide attempts are higher in the girls (ratio of 3, 48:1), which is consistent with the findings in literature that indicate the typical difference between sexes [19,20].…”

SummaryIntroduction: Suicide is the second largest cause of mortality in the 10-24 age group. Investigation of suicide attempts among children and adolescents are rare in Serbia.Objective: The aim of this study is to analyze suicide attempts of children and adolescents who were hospitalized during the twelve -year period (2003.-2014.) in the Clinic of Neurology and Psychiatry for Children and Youth in Belgrade.Method: We retrospectively analyzed medical records of 130 patients. The diagnosis was made according to the ICD 10 criteria. Patients data (gender, age, number of attempts, suicide attempt method, time of year, prior psychiatric diagnosis, family characteristics) were analyzed using standard statistical methods ( Student's t-test and Chi Square test).Results: Gender distribution showed 77.7 % female and 22.3 % male. The mean age was 15.28 years (SD -1.834). The youngest child who attempted suicide was 9.The most common method of attempting suicide was intentional selfpoisoning by drugs (66.2 %), followed by wrist cutting (11.5 %) and hanging (10.8 %). In terms of the gender distribution, statistically significant difference was found in the method of attempting suicide (x2= 12.238; df=4; p=0.016) . The highest suicide rate was in 2013 with 18 attempts, and the lowest was in 2006 with 6 attempts. Most suicide attempts took place in the winter and also in June. 48 patients (36.9%) who attempted suicide had previous psychiatric diagnoses. 14 patients (10.8 %) have at least one member of immediate family who attempted or committed suicide.Conclusion: We confirmed previous results from the literature about gender prevalence and gender differences in method of suicide attempts. Early identification of youth at high risk for suicide behavior is very important, as well as developing specific preventive programs.

“…2 Canadian data from 1980 to 2008 also suggest an increase in suicide rates among female children and adolescents. 1 Multiple theories have been put forward, including an increase in treatment-seeking behaviour 21 and decreased rates of prescribing antidepressants to children following the Food and Drug Administration's (FDA) black box warning. 22 Health Canada issued a similar warning in 2004.…”

“…1 Since 1993, emergency department (ED) visits for suicide-related behaviour among 15-19 year olds have almost doubled (2.57 to 4.53 per 1000 United States population) and are continuing to increase. 2 The role of the Internet, particularly social media, on suicide-related behaviour is a topic of intense debate, 3 and fueled in part by several highly publicized suicides involving social media.…”

OBJECTIVES: Suicide-related emergency department (ED) visits by children are increasing in tandem with suicide-related Internet content. Following the announcement of Amanda Todd's suicide, her YouTube video received widespread views, providing an opportunity to explore this association.METHODS: Our research question was: Among Ontario children age 11-17 years, was the release of Amanda Todd's YouTube video following her death announcement in October 2012 associated with an increase in average monthly ED visit rates for suicide-related diagnoses? We performed an interrupted time series analysis from April 2002 to December 2013, with the primary outcome as a composite of the average monthly rate of initial ED visits for suicidal ideation, intentional self-poisoning, and intentional self-harm. Secondary outcomes were average monthly rates of intensive care unit (ICU) admission and death resulting from the index visit. RESULTS:There was a statistically significant increase in the monthly ED visit rate for the composite outcome (p = 0.02) and death or ICU admission (p = 0.006) from April 2002 to December 2013. There was no significant change in ED visit rate for the composite outcome before and after the announcement of Amanda Todd's death, overall (119.8 versus 219.2 respectively, p = 0.5), among females (167.4 versus 316.8 respectively, p = 0.47) or among males (74.7 versus 116.9 respectively, p = 0.33). CONCLUSIONS:Ontario ED visits for suicide-related diagnoses in 11-17 year olds increased from 2002 to 2013. However, the increase from October 2012 to December 2013 could not be attributed to a highly publicized adolescent suicide. Our findings suggest that suicide-related Internet content is not associated with the increase in ED visits for suicidal behaviour.KEY WORDS: Internet; suicidal behaviour; emergency department La traduction du résumé se trouve à la fin de l'article.

“…Par ailleurs, il a été observé que la suffocation était la principale méthode de suicide chez les deux sexes, suivie de l'intoxication chez les femmes et à la fois de l'intoxication et des armes à feu chez les hommes. Ces cons tatations sont comparables à celles d'une analyse antérieure des méthodes de suicide à l'aide de données canadiennes de 1980 à 2008, dans laquelle on avait observé une augmentation des cas de suffocation et une diminution des cas associés à d'autres méthodes de suicide (telles que l'intoxi cation et les armes à feu) chez les jeunes 38 . La surveillance des méthodes employées représente un élément important de la prévention du suicide, car elle permet de limiter l'accès aux méthodes et elle est utile dans le cadre de l'évaluation des inter ventions.…”

Résultats : Le taux de suicide au Canada (hommes et femmes confondus, tous âges, et taux normalisé selon l'âge et le sexe) a diminué, passant de 14,4/100 000 (n = 3 355) en 1979 à 10,4/100 000 (n = 3 926) en 2012, soit une variation annuelle en pourcentage (VAP) de -1,2 % (IC à 95 % : -1,3 à -1,0). Cependant, cette tendance n'a pas été observée chez les deux sexes : chez les femmes, les taux de suicide se sont stabilisés vers les années 1990, tandis que chez les hommes, ils ont continué de décliner au fil du tempsmalgré le fait que les suicides chez les hommes constituent toujours 75,7 % de tous les suicides en 2012. La suffocation (pendaison et strangulation) était en 2012 la principale méthode de suicide (46,9 %) chez les Canadiens de tous âges, suivie de l'intoxication (23,3 %).Au cours de l'exercice 20142015, il y a eu 13 438 hospitalisations au Canada (à l'exclusion du Québec) associées à des blessures autoinfligées -ce qui représente plus de trois fois le nombre de suicides. Au fil du temps, les femmes ont systématiquement présenté des taux d'hospitalisation plus élevés pour des blessures autoinfligées que les hommes, soit 63 % du total. L'intoxication a été la méthode la plus fréquemment déclarée de préjudice auto infligé au cours de l'exercice 20142015, constituant 86 % de toutes les hospitalisations.Conclusion : Les suicides et les blessures autoinfligées demeurent un problème de santé publique grave -mais évitable -qui exige une surveillance constante.
