Resumo
Introduction: The nutritional status
(NS) of patients on hemodialysis (HD)
is a major concern and challenge.
Malnutrition is common in these
patients and is related to poorer clinical
outcomes. Objectives: To assess the
association between the NS and the
interdialytic weight gain (IDWG) of
patients with chronic kidney disease
(CKD) on HD. Methods: Crosssectional study with 322 patients older
than 18 years. The NS was assessed
by body mass index (BMI), percentage
body fat estimated by the sum of four
skinfolds (triceps, biceps, subscapular
and supra iliac), lean body mass (LBM),
serum creatinine and albumin and rate
of nitrogen appearance (PNA). The
IDWG was evaluated from the sum of
the weight difference of 12 hemodialysis
sessions (IDWGm). Results: Considering
the sample into quartiles IDWGm, it was
found that BMI, LBM, serum creatinine
(p < 0.001) and PNA (p = 0.011) were
directly correlated. There was no
association between IDWGm and serum
albumin. Using multivariate analysis,
it was found that the prevalence of
patients with BMI suitability and serum
creatinine were significantly higher for
patients in the bottom quartile with
respect to the first IDWGm. Conclusion:
The NS is positively associated with
IDWG. The results point to the need
for individualized assessment of IDWG
and cautious in order not to generalize
a recommendation that does not meet
the expectations of maintaining and
promoting the nutritional status of these
patients.
