Effect of death of Diana, Princess of Wales on suicide and deliberate self-harm

Background The death of the Princess of Wales in 1997 was followed by wides pread public mourning. Such major events may influence suicidal behaviour. Aims To assess the impact of the Princess's death on suicide and deliberate self-harm (DSH). Method Analysis, using Poisson regression, of the number of suicides and op en verdicts ('suicides') in England and Wales following the Princess's deat h compared to the 3 months beforehand, and the equivalent periods in 1992-1 996. Similar analysis on DSH presentations to a general hospital. Results Suicides increased during the month following the Princess's funera l (+ 17.4%). This was particularly marked in females (+33.7%), especially t hose aged 25-44 years (+45.1%). Suicides did not fall in the week between t he death and the funeral. Presentations for DSH increased significantly dur ing the week following the death (+44.3%), especially in females (+65.1%). Examination of case notes suggested that the influence of the death was lar gely through amplification of personal losses or exacerbation of existing d istress. Conclusions The death of a major public figure can influence rates of suici dal behaviour. For DSH, the impact may be immediate, but for suicide it may be delayed. Declaration of interest None.
