in Italy and Tuscany the resident population aged> 99 reached its all-time high in 2015. Respiratory diseases in men and ischemic heart diseases in women were the leading causes of death for Italian centenarians in 2015. The aim of this study is to describe the mortality of Tuscan centenarians by cause.
population-based observational study using current health data, extracted from the Tuscan Regional Mortality Register. Main outcome measures are: proportional mortality and annual mortality trend at age >99, age-specific mortality rates (85-89; 90-94; 95-99, >99).
at age >99 ischemic heart diseases, cerebrovascular diseases and respiratory diseases are among the top 5 causes of death as in the less elderly age, the relative frequency of tumors decreases and that of the ill-defined causes increases. If ill-defined and ischemic heart diseases are separated, the first cause of death is cerebrovascular diseases in males and senility in females. In the period 2002-2015 at age >99 all-cause mortality fell on average every year by -0.15% for males and -0.14% for females, mortality due to arteriosclerosis decreases -10% (males) and -12% (females) every year, due to cardiac arrest and other non-specific cardiopathies -5% (males) and -7% (females) and due to cerebrovascular diseases -3% (females). Mortality due to senility increases +6% per year in women.
in Tuscany the first cause of death is different by gender (cerebrovascular diseases in males and senility in females) and differs from what has been observed nationally. In the 2000s, mortality from cardiovascular diseases without diagnostic significance decreased in Tuscan centenarians and that from senility increased.
