Abstract
Background
Studies in a few countries (including the US) have reported that mortality rates in the population from psychiatric disorders
are much higher when they are based on all causes of death (“multiple causes” or “mentions”) coded on death certificates versus
only the underlying cause. Studies appear to be lacking on geographic variation within the US in mortality rates from psychiatric
disorders based on multiple causes of death.
are much higher when they are based on all causes of death (“multiple causes” or “mentions”) coded on death certificates versus
only the underlying cause. Studies appear to be lacking on geographic variation within the US in mortality rates from psychiatric
disorders based on multiple causes of death.
Results
For the entire US, the ratio of the ASR based on multiple causes to the ASR based on underlying cause was 20.9 for depression
and 9.2 for schizophrenia; in analyses by region and division, these ratios showed limited variation. The most consistent
finding for both depression and schizophrenia was that ASRs, whether based on multiple causes or only on underlying cause,
were highest in the Midwest region (especially the East North Central division) and lowest in the South (and in each of its
three divisions). For ASRs (using multiple causes of death) from depression, these regional differences were evident within
each of several levels of urbanization. For deaths with depression coded as other than the underlying cause, ASRs for each
of the three most common underlying causes (cardiovascular diseases, intentional injuries, and neoplasms) were highest in
the Midwest and lowest in the South.

Conclusion
Studies are needed to determine if these regional differences in mortality from depression are due to regional differences
in: certifier practices (i.e., in assigning causes of death among persons with psychiatric conditions); the prevalence (among
persons with psychiatric disorders) of lifestyle-related factors (e.g., tobacco use and obesity) that mediate mortality risks;
and/or in unmet need for psychiatric treatment and medical care for other chronic diseases in persons with psychiatric conditions.
Similar studies are needed of regional variation within other countries.
