Objective characterize the hospital morbidity of adults living in the city of Maringá,
PR, Brazil, between 2000 and 2011, focusing on the differential between men
and women. Method this descriptive study was developed based on data from the Hospital
Information System of the Unified Health System in order to investigate the
association between groups of hospitalization causes and the average length
of hospitalization per gender, in three-year periods. Results the main groups of hospitalization causes for men were: mental disorders,
lesions and circulatory diseases; and, among women: tumors, circulatory and
genitourinary diseases. Mental disorders and lesions, tumors, circulatory
and genitourinary diseases were significantly associated with the female and
male genders across the study period. Although not significant, the mean
length of hospitalization dropped across the four three-year periods, and
only showed a significant difference between men and women in the second
triennium. Conclusion differences in the hospital morbidity profile between men and women
underline the need for specific health and nursing actions, especially in
primary health care, with a view to reducing hospitalizations due to the
main groups of causes in the city.
