Background and Aim: Hoarding cases have not been researched in depth in developing countries, such as Brazil. This study aimed to describe the characteristics of people with hoarding behavior in Curitiba, Brazil.

Materials and Methods: A cross-sectional study was conducted based on complaints about hoarding situations received by the City Hall. The data on sociodemographic, income, and environmental characteristics of individuals displaying animal and object hoarding behavior were obtained and analyzed using descriptive statistics and multiple correspondence analyses.

Results: Out of the 113 hoarding cases reported, 69 (61.06%) were fully assessed. Most of the participants (43; 62.32%) were women, and it was observed that most of the animal hoarding cases were women (p=0.02). The average age was 62.47 years old, and most of them (44; 63.76%) had studied up to the middle school level. People associated with object hoarding belonged to the lower income category (p=0.031). In most cases, the homes had an unpleasant odor (45; 65.21%), and this was prevalent in cases involving women (p=0.004) and animals (p=0.001). The risk of fire (24 [34.78%]) and landslip (9 [13.04%]) was more frequent in the case of object hoarding (p=0.018 and 0.021, respectively).

Conclusion: The description of characteristics of individuals with hoarding behavior may assist in understanding the magnitude of this public health problem in Brazil and shed light on the need to develop studies on the health conditions of people and animals that live in these situations.
