## TL;DR

This paper explores how fuzzy logic can help understand the vulnerability of women who have sex with women to sexually transmitted infections and HIV/AIDS.

## Contribution

The study introduces a fuzzy logic system with 17 input variables to analyze vulnerability in a specific population.

## Key findings

- Low understanding of STIs/HIV/AIDS is strongly linked to higher vulnerability.
- Not disclosing sexual activity to healthcare professionals had the least impact on vulnerability.
- Fuzzy logic effectively identifies vulnerability through variable interactions.

## Abstract

To describe the possibility of applying Fuzzy Logic in analyzing the vulnerability of Women Who Have Sex with Women to Sexually Transmitted Infections/HIV/AIDS.

We developed a Fuzzy Logic system with 17 input variables and one output variable, using data related to vulnerability in a municipality located in the Midwest region of the State of São Paulo, Brazil.

The factor with the greatest positive impact was the confirmation that a low understanding of Sexually Transmitted Infections/HIV/AIDS is associated with higher vulnerability. Conversely, the statement “Not disclosing sexual activity to healthcare professionals,” where individuals do not admit to having sex with women, had the least impact.

Fuzzy Logic facilitates the identification of vulnerability, expressed through the analysis of interaction between variables in each dimension. This makes it a promising method to assist in analyzing the vulnerability of specific populations.

descrever a possibilidade de aplicação da Lógica Fuzzy na análise da vulnerabilidade de Mulheres que fazem Sexo com Mulheres às Infecções Sexualmente Transmissíveis/HIV/aids.

Desenvolveu-se um sistema de Lógica Fuzzy com 17 variáveis de entrada e uma de saída, utilizando dados relacionados à vulnerabilidade em um município localizado no Centro-Oeste do Estado de São Paulo, Brasil.

O fator de maior impacto positivo foi a confirmação de que a baixa compreensão sobre Infecções Sexualmente Transmissíveis/HIV/aids está associada a uma maior vulnerabilidade. Por outro lado, a declaração “Não se expor para a profissional de saúde”, onde a pessoa não admite ter relações sexuais com mulheres, teve o menor impacto.

A Lógica Fuzzy oportuniza a identificação da vulnerabilidade, expressa pela análise de interação entre as variáveis de cada dimensão. Isso a torna um método promissor para auxiliar na análise da vulnerabilidade de populações específicas.
