Elderly suicide rates: a replication of cross-national comparisons and association with sex and elderly age-bands using five year suicide data

BACKGROUND Suicide rates generally increase with age. A recent cross-national study, using one-year cross-sectional data on suicide rates identified regional and cross-national patterns for elderly suicide rates. However, findings from studies using one-year cross-sectional data on suicide rates may be open to bias because of random year on year fluctuations in elderly suicide rates. METHODS One-year average of suicide rates for both sexes in the age-bands 65-74 and 75+ years were calculated from data on suicide rates for five consecutive years ascertained from the World Health Organization. Cross-national variations were examined by segregating different countries into four quartiles of suicide rates. RESULTS There was wide cross-national variation in elderly suicide rates. Elderly suicide rates were the lowest in Caribbean and Arabic/Islamic countries, and the highest in central and eastern European, countries emerging from the former Soviet Union, some oriental and some west European countries. CONCLUSIONS The regional and cross-national patterns for elderly suicide rates observed in this study were almost identical to a similar earlier study using one-year cross-sectional data on suicide rates. This suggests that the findings of both studies were accurate and robust, and potential explanations for the observed cross-national variations in elderly suicide rates requires further study.
