Seasonal variation in suicides: diminished or vanished: Experience from England and Wales, 1982–1996

  • Paul S. F. Yip (a1), Anne Chao (a2) and Calvin W. F. Chiu (a3)

Extract

Background

Seasonal variation in suicidal death has been observed in many countries. In particular, a cyclic variation was found for both men and women in England and Wales in the 1960s and 1970s. Men showed a single 12-month cycle whereas women showed two cycles.

Aims

To re-examine the seasonal variation in suicides in England and Wales for the period 1982–1996.

Method

A harmonic analysis was used to detect the seasonality of the suicide data.

Results

The seasonal effect on suicide is greatly diminished in England and Wales. This is shown by the reduced amplitude and smaller proportion of variance accounted for by the season.

Conclusions

The seasonal effect on suicide has either diminished or vanished.
