Systemic arterial hypertension (SAH) and diabetes mellitus (DM) are chronic non-communicable diseases that are major health problems in Brazil, due to their high prevalence and the risk factors associated with cardiovascular diseases, leading to a reduction in the population's quality of life and life expectancy, high morbidity and mortality rates and social and economic costs resulting from the use of health services. In view of this, it is important to know how to prevent these diseases and their complications. The aim of this study was to determine the prevalence of hypertension and diabetes among individuals participating in the Action against Poliomyelitis, which is carried out annually by Rotary and on October 20, 2023 was held in partnership with medical students from the municipality of Guarujá. This was a cross-sectional, descriptive study with a quantitative approach. Sample data was collected at the Horácio Lafer square, where blood pressure was measured and capillary glycosimetry was performed. The study population consisted of 57 patients. The sociodemographic profile, prevalence of hypertension, glycemic profile and prevalence of associated hypertension and diabetes were analyzed. The results showed that there was a predominance of females (56.14%), 32 of whom were aged 19-85, and 25 males (43.85%) aged 17-74. With regard to the prevalence of hypertension, it was possible to see that 6 women and 7 men were hypertensive and 44 individuals had normal blood pressure levels. As for the glycemic profile, 3 women and 3 men had altered random blood glucose levels.One 66-year-old female had associated hypertension and diabetes, with values of 160-120mmHg and 160mg/dL. It is understood that early identification and personalized management of hypertension and DM are fundamental to avoiding complications and improving patients' quality of life. Strategies adapted according to gender and age are necessary to promote health and ensure adherence to treatment, highlighting the importance of ongoing educational programs and specific screening strategies to address this growing health challenge.
