ANDRADE, Vanessa Maggitti Bezerril Andrade. Antropometric state, self-perception and
food intake of the weight in adolescentes from public schools from Salvador. Dissertação
(Mestrado) – Universidade Federal da Bahia, Salvador, Bahia, 2018.
Introduction: There is a significant increase in the number of overweight and obese children
and adolescents in the world. Changes in food consumption coupled with physical inactivity
and other lifestyle habits are considered as potential causes of this scenario. Paradoxically,
promotes the idealization of a leaner body appearance. Under these circumstances,
perceptions of adolescent weight patterns can be easily affected. The complex relationship
between the actual value of weight and body image is an important factor influencing
adolescent health. Few studies have evaluated the interaction between anthropometric status,
body image and dietary pattern in a systematic way, including in Brazil.
Objective: To evaluate the association between anthropometric status and / or the divergence
between the measured and perceived weight and food consumption of adolescents enrolled in
public schools in Salvador, Bahia.
Methods: A cross-sectional study was conducted in 23 public schools in Salvador (Bahia),
which evaluated 1496 adolescents randomly selected by the process of sampling by clusters
in two stages, first the school and according to the student. The collection of demographic
information, economic condition, anthropometric status, food consumption and selfperception
of weight was performed. The semi-quantitative food frequency questionnaire was
used to collect food consumption information. The food consumption pattern was considered
the analytical outcome and was evaluated by cluster analysis. A logistic regression model was
adopted to evaluate associations between divergence between measured and perceived weight
stratified by anthropometric status and dietary patterns. In addition, analyzes of correlation
networks were used to perform a detailed description of the food consumption profile and its
relationship with the anthropometric state and the divergence between measured and
perceived weight. For the statistical analysis, we used the programs SPSS 24, GraphPad
Prism 7.0 and statistical packages of program R.
Results: A prevalence of 31.7% was found between the measured and perceived divergence
with the anthropometric status in schoolchildren from the city of Salvador. Four dietary
patterns were identified through hierarchical cluster analysis and k-means: 1) Standard 1,
composed of beans, cereals, sugary drinks and sugar and sweets; 2) Standard 2, characterized
by the consumption of cereals, beans, coffee and sugary drinks; Standard 3, consisting of
sugary drinks, cereals, fruits, coffee, beans and typical Bahian dishes and Standard 4,
consisting of sugary drinks and beans. For adolescents of both sexes with thinness / eutrophy,
the results indicated a negative association between overestimation of the current weight and
adherence to dietary standards 1 and 4 (female: pattern 1- odds ratio [OR] 0.5; 95%
confidence interval [CI]: 0.4-0.9; Standard 4 OR 0.3; 95% CI: 0.2-0.9; male: pattern 1- OR
0.8; 95% CI: 0.6-0.9; pattern 4 OR 0.5, 95% CI: 0.1-0.9). In this group, adolescents who
underestimated were more likely to consume pattern 2 (female OR 1.3, 95% CI 1.1-1.3, male
OR 1.2, 95% CI 1, 1-2,1). In overweight / obese adolescents who overestimated body weight,
there was a lower chance of adherence to dietary pattern 1 (OR 0.4, 95% CI: 0.1-0.6 for
female and OR 0.5 CI 95%: 0.2-0.8 for males), and more likely to adhere to pattern 4 (OR 1.8
95% CI: 1.1-2.8 and OR 2.0, 95% CI: 1.1% 3.5, female and male respectively). Overweight /
obese male had lower adherence in consuming food groups from pattern 3 (OR 0.8; 95% CI:
0.6-1.0). Analyzes of correlation networks showed that in the presence of overweight and
obesity there were negative correlations in the intake of certain food groups. Thus,
adolescents with obesity reported having a higher number of these correlations, that is, when
there was food intake from the group vegetables, the adolescent consumed less food from the
fast food groups, sausages, cereals and coffee, or when food was consumed of the bean group
consumed less food from the groups milk and dairy products, sugar and sweets, sugary drinks
and coffee. When these correlations were evaluated in the groups according to the difference
between measured and perceived weight, individuals who overestimated the weight,
compared with those who agreed or underestimated body weight, had greater negative
correlations of consumption of food groups, that is, when they consumed food of the roots
group consumed less food from the built-in groups, oils and fats, coffee.
Conclusions: The present study identified a high prevalence of divergence between
measured and perceived weight among schoolchildren. Negative and positive associations
were identified among individuals with thinness / eutrophy or overweight, who
underestimated or overestimated body weight, and eating patterns characterized mainly by
foods with a high glycemic index (cereals, sugary drinks, sugar and sweets). Correlations
network analysis showed that inappropriate food choices can be determined by the presence
of overweight, obesity and among individuals who overestimate body weight. The set of
analyzes that compose the dissertation adds important information about the food
consumption of schoolchildren in the city of Salvador and its relations with the
anthropometric state and with the divergence between the measured and the perceived
weight. Such knowledge may serve as a basis for future investments in the field of nutritional
epidemiology in Brazil.
