Objectives: to identify the main causes for hospital admissions and deaths related to
systemic arterial hypertension and diabetes mellitus (DM), and to analyze
morbidity and mortality trends, in a municipality in São Paulo's countryside, by
comparing two three-years periods, 2002 to 2004 and 2010 to 2012. Methods: cross-sectional study which used secondary data regarding deaths from the
Information System on Mortality and concerning hospital admissions from the
DataSus Hospital Information System. Univariate and multivariate statistical
analyses were conducted. Results: from 2002 to 2012, 325,439 people were admitted to hospitals, 14.7% of them due
to circulatory system diseases (CSD) and 0.7% due to DM. The deaths distributed as
the following: 29,027 deaths (31.5%) were due to CSD; 8.06% due to cerebrovascular
diseases (CVD); and 2.75% due to DM. There was a significant association between
admittance and death causes and patients' gender and age in the three-year periods
(p<0.001). The highest lethality in hospital admissions was found to be due to
CVD (10%). That trend showed that mortality rates dropped, younger patients were
admitted due to DM, and older patients were admitted due to CVD - they were more
often females. Conclusion: the main causes for hospital admissions were the CSDs; main mortality causes were
the CVDs in hypertensive and diabetic women. Those findings can back public
policies which prioritize the promotion of health.
