Re-examination of the seasonality of suicide in Taiwan during 1991-2008: A population-based study.
Summary of "Re-examination of the seasonality of suicide in Taiwan during 1991-2008: A population-based study."
The purpose of the present study was to re-examine the monthly distribution of suicide death rates and the change of the suicide seasonality in Taiwan during 1991-2008. The monthly suicide death rates of the total, male and female populations during January 1991-December 2008 were obtained from a population-based database. There was an upward trend. The means of the monthly suicide rates after adjusting the calendar effect and the upward trend were compared. The suicide data were further analysed in three 6-year periods to explore the change of seasonality. During 1991-2008 in Taiwan, suicide rates had significant peaks in April and May, and nadirs in January and December. The monthly distributions varied during 1991-1996, 1997-2002 and 2003-2008 in the patterns and the statistical significance. There was no linear trend for the change of the seasonality of suicide death rate.

Medical and Biotech [MESH] Definitions
Population Surveillance
Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.
Self-examination
The inspection of one's own body, usually for signs of disease (e.g., BREAST SELF-EXAMINATION, testicular self-examination).
Sudden Infant Death
The abrupt and unexplained death of an apparently healthy infant under one year of age, remaining unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of the clinical history. (Pediatr Pathol 1991 Sep-Oct;11(5):677-84)
Incidence
The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases, new or old, in the population at a given time.
