Prevalence and Determinants of Predialysis Dietitian Follow-Up: Results From the Brazilian Dialysis Registry


      We aimed to evaluate the prevalence and sociodemographic determinants of predialysis dietitian follow-up in a large cohort of Brazilian dialysis patients.


      We retrospectively evaluated data from all incident adult dialysis patients included in the Brazilian Dialysis Registry from January 2011 to September 2021. Predialysis dietitian follow-up was classified as present when a period more than 6 months of dietitian care was reported. Gender, age, skin color, education, body mass index, chronic kidney disease etiology, first chronic dialysis program, healthcare provider, and geographic regions were tested in logistic regression models.


      Ten thousand three hundred and eighty two patients met the inclusion criteria and 1,254 (12.1%) reported predialysis dietitian follow-up, most of them referred by a nephrologist (94.2%). The independent determinants of dietitian follow-up were older age, white skin color, higher education level, not having diabetes, living in North/Northeast and South (compared to Southeast), and having a nonpublic healthcare provider. When considered only patients under a predialysis care of a nephrologist, higher education, hemodialysis as the first dialysis modality, and living in the North/Northeast and South regions (compared with Southeast) were associated with dietitian follow-up.


      Predialysis dietitian follow-up for more than 6 months in a country where the public health system is the main dialysis provider is still very low. The nephrologist is pivotal for referral to dietitians but socioeconomic factors also seem to play a role in this regard.
