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.

Background: Elderly suicide rates may be influenced by mental health funding, service provision and national policy.

Methods: A cross-national study examining the relationship between elderly suicide rates and (i) the presence of national policy on mental health, (ii) funding for mental health, and (iii) measures of mental health service provision was undertaken by utilizing data from the World Health Organization website.

Results: The main findings are: (i) there is no relationship between suicide rates in both sexes in both elderly age-bands and different measures of mental health policy, except they were increased in countries with a substance abuse policy; and (ii) suicide rates in both sexes in both elderly age-bands were higher in countries with greater provision of mental health services, including the number of psychiatric beds, psychiatrists, psychiatric nurses, and the availability of training in mental health for primary care professionals.

Conclusions: Cross-national ecological studies using national-level aggregate data are not helpful in establishing a causal relationship (and the direction of this relationship) between elderly suicide rates and mental health funding, service provision and national policies. The impact of introducing national policies on mental health, increasing funding for mental health services and increasing mental health service provision on elderly suicide rates requires further examination in longitudinal within-country studies.
