Resumo
Objective: To evaluate dietary fibre intake in Brazilian adolescents and its associ-
ation with nutritional status.
Design: This was a cross-sectional study including data from the Brazilian multi-
centre Study of Cardiovascular Risks in Adolescents (ERICA). Data analysed were
geographic region, sex, age, nutritional status, sexual maturation stage, socioeco-
nomic status, school type and level of physical activity. For nutritional status
classification, BMI/age was used by sex. Dietary intake was assessed by 24-h recall.
Dietary fibre intake was expressed in g/d, and adequacy was determined using
dietary reference intake (DRI) values. Complex sample design was considered
in statistical analysis, and logistic regression was used to estimate OR for fibre
intake and nutritional status.
Setting: Brazilian municipalities with more than 100 000 inhabitants.
Participants: A total of 71 740 adolescents aged 12–17 years were included.
Results: The average total dietary fibre intake was 19·1 g/d (95 % CI 18·5, 19·7), and
only 13·1 % (95 % CI 11·6, 14·7) of Brazilian adolescents reached the recommen-
dations. The results of logistic regression analysis adjusted for geographic region,
sex and type of school showed that overweight and obese adolescents were
1·6 and 1·8 times more likely, respectively, to have inadequate dietary fibre intake
(P < 0·0001).
Conclusions: Brazilian adolescents had a significantly inadequate dietary fibre
intake. This was particularly notable in adolescents with excess weight.
Education policies on nutrition must be implemented, as dietary fibre plays an
important role in the prevention and treatment of obesity and other chronic
diseases.
