Objectives: The aim of this research was to determine the attitudes and knowledge of adults in the general population about diabetes. Respondents and procedures: In order to examine the knowledge of pharmacists, a cross-sectional survey was conducted using an anonymous survey questionnaire during September 2024. The processed data was collected online through a Google Forms form, the link of which was forwarded to the respondents. Respondents included in this research are adults from the general population in Croatia who wanted to participate anonymously in an online survey. Results: A total of 200 respondents from the adult general population participated in the research. Respondents who have a person with diabetes in their environment did not show a statistically significant difference compared to the others when it comes to answers such as the genetic factor of diabetes (P= 0,532), taking care of the feet (P= 0,687), using multiple medications (P= 0,727), insulin use (P= 0,621), visual impairment due to diabetes (P=0,098). The relationship with a person suffering from diabetes did not affect the understanding of the genetic predisposition to the disease, frequent comorbidities and complications of the disease, and the patient's therapy itself. Conclusion: The research found that the majority of the surveyed general population is well informed and aware of diabetes as a chronic disease, its causes and complications, indicating a high level of awareness about diabetes.
