Self-perception of food intake and dietary quality

Marcela Ribeiro da Costa, Crésio de Aragão Dantas Alves


Introduction: Self-perception of dietary quality has been associated with weight and body composition,
as well as dietary pattern. Both the gain and maintenance over the long term of excess weight have
been frequently associated to dietary and life habits of individuals, which justifies the improvement of
assessment methods. Methods: Convenience sample consisting of 14 women who took classes at
Contours® gym, aged 18-45 years. Data collection was performed in two stages: the first consisted in
the application of questionnaires designed specifically for the research on socioeconomic data, general
information on health and the regular use of drugs, self-perception of dietary habits and a 24-hour recall.
In the second stage, collection of the 24-hour diet recall was performed. The Revised Diet Quality Index
(RDQ-I) was used in the assessment of dietary standards. Results: In the assessment of eating habits,
85.7% of the respondents were classified as healthy. Most of them, 78.57%, rated their dietary pattern
as positive, 14.3% were not able to rate it and 7.13% rated it negatively. The Spearman correlation
coefficient indicated that there was a moderate positive correlation between the RDQ-I (Revised Diet
Quality Index) and self-perception. Conclusions: There is a statistical significant correlation of dietary
pattern and dietary quality.
