Abstract
Purpose
To examine if widespread media reporting of the suicide of a young female singer by charcoal burning increased suicide rates, and to examine whether the suicide induced a high risk of imitation suicide by this method among the young female group.
Methods
Poisson time series autoregression model was applied to examine the relative risk of overall and subgroup (age, gender and method) suicides during the 2-week period after the initiation of media reporting of the celebrity suicide.
Results
We found a significant increase (adjusted relative risk = 1.17, p = 0.04) in suicide deaths following media reporting of the celebrity suicide. The increase in suicides was particularly significant among female and young age groups. A marked increase in suicide by charcoal burning among females (adjusted relative risk = 1.44, p < 0.0001) was further observed.
Conclusions
Detailed description of a specific suicide method following celebrity suicides may induce extensive modeling effect, attracting wider age/sex groups to model the method. Our finding provides further support for restraining media reporting of celebrity suicide in suicide prevention.

Appendix: Poisson autoregression model
The autoregressive model (order 1) can be expressed as follows:
where Y(t) is the variable measured in the time period t and is a function of the variable itself measured at the previous period t − 1. The first-order Poisson autoregressive model can be fitted using SAS GENMOD procedure by specifying the link function as the log link, the random error as Poisson distribution and the correlation matrix as the autoregressive (AR) type.
