Summary: Introduction: Bariatric Surgery (BS) is a procedure for the treatment of
severe obesity. The reduction in gastric capacity promoted by BC can affect
food intake and compromise the quality of the diet. The Healthy Eating Index
(IAS) is a validated tool that allows you to classify diet quality.
Objective: To relate the quality of the diet with changes in body
composition, biochemical profile of the nutritional and inflammatory status
of patients undergoing BS. Methodology: This is a study carried out with
patients from the Bariatric and Metabolic Surgery Program at the Cassiano
Antônio Moraes University Hospital. The research participants were evaluated
in three moments from April 2016 to March 2020: before surgery (T0),
approximately in the second (T1) and sixth month (T2) after the BS.
Anthropometric parameters were evaluated: body mass index, waist
circumference, fat mass and lean mass; biochemical parameters: total proteins
and fractions, transthyretin, C-Reactive Protein (CRP) and Alpha-Acid
Glycoprotein (α1-GA). Diet quality was assessed by IAS. Data were analyzed
by repeated measures ANOVA or Friedman`s test, according to data
distribution. For the correlation analysis, the Pearson or Spearman test was
used and for the association analysis, the simple linear regression analysis
test was used, adjusted for sex and age. A significance level of 5% was
adopted. Results: The sample consisted of 22 individuals, 81.8% (n=18)
female. Individuals had poor diet quality at all times evaluated. BS promoted
a reduction in all anthropometric parameters analyzed, and in serum levels of
transthyretin and CRP (p<0.05). There was a negative correlation and
association between the SAI with all anthropometric parameters and a positive
association with transthyretin (p<0.05) at T2. The variation in serum
transthyretin concentrations was positively correlated with the variation in
IAS and caloric intake (p<0.05). Conclusion: The individuals in the present
study had poor diet quality during the period evaluated, which may indicate a
concomitant loss of visceral protein mass.
