Resumo
Avaliar o padrão alimentar de adolescentes com adequação pôndero-estatural e elevado percentual de gordura corporal (%GC). Realizou-se um estudo transversal com 99 adolescentes, sendo 70% do sexo feminino. Utilizou-se o índice de massa corporal para diagnosticar adequação pôndero-estatural, segundo a World Health Organization. Obteve-se o %GC pelo somatório das pregas cutâneas, conforme Durnin e Rahaman, considerando elevados os valores >25% (sexo feminino) e >20% (masculino). Aplicou-se um questionário para investigação do hábito alimentar. A mediana de refeições diárias era quatro. O jantar era a refeição mais omitida, entretanto, a maioria o substituía por lanche. Omissão do jantar e realização do lanche da tarde foram mais freqüentes entre as adolescentes (p <0,01). Aproximadamente 11% omitiam o desjejum. Fracionamento da dieta e ingestão alimentares, exceto de hortaliças, foram reduzidos pela maioria, nos últimos anos. Cerca de 81% e 31%, respectivamente, mencionaram alterar a ingestão do grupo das gorduras/doces e o das hortaliças, nos finais de semana, consumindo mais alimentos doces e gordurosos e menos vegetais. O grupo mais rejeitado era o das hortaliças. Aproximadamente 40,5% utilizavam alimentos diet/light. A pesar da adequação pôndero-estatural e da aparente preocupação em controlar o peso, esses adolescentes estão sob risco nutricional, devido ao elevado %GC e aos importantes erros alimentares.
Alterations in the feeding patterns of adolescents as related to weight-height adequacy and high body fat percentage (%BF). A cross-sectional study was carried out with 99 adolescents, 70% females. The body mass index was applied to diagnose weight-height adequacy, according to the cut-off point established by the World Health Organization. %BF was obtained by the sum of skinfolds, according to Durnin and Rahaman, considering the values >25% (females) and >20% (males) high. A questionnaire was applied to investigate the feeding pattern. The median of daily meals was four. Dinner was the most skipped main meal, however, the majority replaced it by a snack. Skipping dinner and having a snack in the afternoon were more common among girls (p <0.01). About 11% skipped breakfast. In the last years, meal frequency and food intake, except for vegetables, were reduced by the majority. On weekends, about 81% and 31% of the adolescents, respectively, modified the fat and sugar class and the vegetable class intake, consuming more sweets, fat foods and less vegetables. The most rejected food class consisted of vegetable. About 40.5% used diet/light food. Despite the weight-height adequacy and apparent concern related to weight control, these adolescents are under nutritional risk because of the high %BF and important feeding inadequacies.
