title: Are elderly suicide rates improved by increased provision of mental health service resources? A cross-national study.
abstract: BACKGROUND
  Elderly suicide rates may be influenced by mental health service provision.
  
  
  METHODS
  A cross-national study examining the hypothesis that the relationship between elderly suicide rates and markers of mental health service provision would be curvilinear (inverted-U shaped curve) and fit the quadratic equation y = a + bx - cx2 (where y is the elderly suicide rate, x is a marker for mental health service provision, and a, b and c are constants) was undertaken by utilizing data from the World Health Organization.
  
  
  RESULTS
  The relationship between the logarithm of suicide rates in both sexes in both the elderly age-bands and the percentage of the total health budget spent on mental health, the total number of psychiatric beds per 10,000 population and the total number of psychiatrists per 10,000 population were curvilinear (inverted U-shaped curve) and fitted the quadratic equation y = a + bx - cx2 with statistical significance.
  
  
  CONCLUSIONS
  The direction of the causal relationship could be examined in longitudinal studies, after further improvement in levels of mental health service provision, in individual countries segregated by low and high levels of existing mental health service provision.
