Bottom Line: These qualities were more strongly associated among those who followed celebrity suicide with intermediate and high effect sizes than lower.Younger suicide victims were significantly associated with higher effect size, female gender, white collar employment, unmarried status, higher education, death by hanging, and night-time death.Characteristics of celebrities were significantly associated with those of general population in hanging method and gender.

ABSTRACT

Objective: Although evidence suggests that there is an increase in suicide rates in the general population following celebrity suicide, the rates are heterogeneous across celebrities and countries. It is unclear which is the more vulnerable population according to the effect sizes of celebrity suicides to general population.

Methods: All suicide victims in the general population verified by the Korea National Statistical Office and suicides of celebrity in South Korea were included for 7 years from 2005 to 2011. Effect sizes were estimated by comparing rates of suicide in the population one month before and after each celebrity suicide. The associations between suicide victims and celebrities were examined.

Results: Among 94,845 suicide victims, 17,209 completed suicide within one month after 13 celebrity suicides. Multivariate logistic regression analyses revealed that suicide victims who died after celebrity suicide were significantly likely to be of age 20-39, female, and to die by hanging. These qualities were more strongly associated among those who followed celebrity suicide with intermediate and high effect sizes than lower. Younger suicide victims were significantly associated with higher effect size, female gender, white collar employment, unmarried status, higher education, death by hanging, and night-time death. Characteristics of celebrities were significantly associated with those of general population in hanging method and gender.

Conclusion: Individuals who commit suicide after a celebrity suicide are likely to be younger, female, and prefer hanging as method of suicide, which are more strongly associated in higher effect sizes of celebrity suicide.

Figure 1: Forest plot of effect estimates in suicide numbers during affected periods compared with reference periods, and 95% confidence intervals (CIs) from 13 celebrity suicides. The pooled random-effects estimate and the corresponding 95% CI are also shown (n=94845). **p<0.01, ****p<0.0001.

Mentions: Figure 1 displays the Forest plot of estimates for changes in suicide numbers during affected periods compared with reference periods. Among 94,845 suicide victims, 17,209 completed suicide within one month after a celebrity suicide (18.1%). Effect sizes after celebrity suicide showed a large variation, from -8.1 to 29.7. The random-effects combined estimate of 13 celebrity suicides indicated an average increase in the daily suicide number of 6.7 [95% confidence interval (CI) 2.1-11.3] in the affected periods. Four relevant periods (for cases 1, 2, 6 and 9) showed a significant increasing effect. The suicide of a famous actress Ms. Choi (case 6), led to the biggest change of national daily suicide numbers (estimate=29.7, 95% CI 16.5-42.9).
