Abstract
<title>Abstract</title> <p> <bold>Background:</bold> Chronic kidney disease is a major public health problem, particularly among patients undergoing hemodialysis, as prolonged treatment may affect their socioeconomic, dietary, and nutritional conditions. Food insecurity, low income, and inadequate dietary intake may compromise nutritional status and treatment effectiveness. In this context, investigating to evaluate hemodialysis treatment duration and its association with socioeconomic and demographic indicators, food insecurity, and nutritional adequacy in chronic kidney disease patients is essential. <bold>Study Design:</bold> This is a cross-sectional quantitative study. <bold>Location</bold> : at a referral hemodialysis center. <bold>Participants</bold> : The population consisted of patients who had been on hemodialysis for at least 6 months. Socioeconomic, demographic, and food vulnerability data were collected based on food insecurity and nutritional adequacy. <bold>Results:</bold> The majority of the population is composed of adults (70.0%), most of whom reported having a family support network (88.8%). Unemployment was more prevalent (58.1%), followed by low income, with 74.4% earning up to R$ 2,400.00 or irregular income. Concerning food vulnerability, 80% of the population experienced some degree of food insecurity. Most patients had a low consumption of essential foods, such as beef, chicken, milk, fruits (with low level of potassium), beans, and tubers. Lower-quality foods, such as cold cuts, cheese, butter, preserved breads and candies, were frequently consumed by the majority and were classified as foods rich in sodium, fats, and sugar, compromising both health and the effectiveness of dialysis treatment. Regarding nutritional adequacy, 75% of patients did not meet nutritional recommendations. <bold>Conclusion:</bold> Longer hemodialysis duration is associated with increased socioeconomic and dietary vulnerability as well as nutritional adequacy for nutritional therapy in hemodialysis patients. </p>
