Background Kidney diseases are silent killers with huge consequences that man has been attempting to eradicate for years, but with little success. Knowing the exact nature of the cause, signs, and symptoms that indicate a decline in kidney function could help detect disease development earlier. This study looked at people's knowledge of kidney failure's causes, signs, and symptoms as a determinant of kidney failure risk behavior. Objective The goal was to discover if people's knowledge of kidney failure's causes, signs, and symptoms could help with early illness identification. Methods A descriptive survey research design with a multistage sampling procedure was used to pick 331 respondents for the study. The study's instrument was a structured self-administered questionnaire with a reliability coefficient of 0.81. Three hypotheses were developed and using SPSS, the chi-square test was employed to assess the hypotheses at the 0.05 level of significance. Results The findings revealed that knowledge of causes and knowledge of signs and symptoms were significant determinants of kidney failure risk behaviors (X2cal= 110.97, X2crit= 19.68, df= 11, p 0.05; X2cal= 52.70, X2crit= 35.172, df= 23, p 0.05) and that there was no significant gender difference in knowledge of kidney failure causes (F=0.049, df=329, p> 0.05). Conclusion We found that knowledge of causes, signs, and symptoms is a significant factor of kidney failure risk behaviors among workers in Ede North Local Government Area of Osun State, Nigeria, based on the findings of this study. We also concluded that there is no significant gender difference in knowledge of the causes of kidney failure among these workers.
