Summary: Background: Interdialytic weight gain is an important marker of adherence to nutritional and water recommendations in haemodialysis users. Objetives: The study aimed to evaluate the factors associated with interdialytic weight gain in users of haemodialysis. Materials and methods: This is an cross-sectional epidemiological study with 1024 individuals with chronic kidney disease on haemodialysis in Brazil. Interdialytic weight gain was evaluated by the percentage weight gain between one haemodialysis session and another. The variables included in the binary logistic regression analysis were selected by considering p< 0.10 in the bivariate test. Results: We demonstrated that having more years of study (OR=0,525;CI 95% = 0,302–0,913; p=0,023) and be overweight (OR=0,651;CI 95% = 0,453–0,935; p=0,020) or obese (OR=0,379;CI 95% = 0,240–0,597; p=0,000) reduced the chances of users having high interdialytic weight gain. Those who did not have paid work (OR=1,969;CI 95% = 1,181–3,285; p=0,009) and not adopting measures to reduce salt increased (OR=1,647;CI 95% = 1,050–2,583; p=0,030) increased the chances of interdialytic weight. Conclusions: The results point to the need for knowledge about the factors associated with interdialytic weight gain in order to individually target the health of this population.
