Circulatory diseases are the main cause of death in the world. Although in Brazil

2016, circulatory diseases (CID-10 IX) were the second cause
1 of morbidity in the
State of Paraná. In relation to respiratory diseases (CID-10 X), the Southern region
of Brazil presents the highest morbidity rates, and Paraná, one of the three states in
this Region, generally presents the highest rates, in some years superseded by the

morbidity in the State of Paraná (Paraná 2017).
Variables and Data Sources Box 1 presents all variables applied in the study, their
description and sources. The studies involved variables such as: demographic density (DD), gross domestic product (GDP), municipal Human Development Index
(M_HDI), percentage of households with adequate sanitation (SNT), percentage of
urban households in streets with trees (ARB), percentage of urban households in
streets with urbanization (URB), number of vehicles (VHCLS), morbidity of respiratory diseases (RD) and morbidity of circulatory diseases (CD) per municipality in
