RESUMO

Estudo transversal de base escolar que avaliou a prevalência e fatores associados ao consumo diário de refrigerantes, doces e frituras em adolescentes (15-20 anos) da rede pública estadual de Caruaru (PE), em 2007. Para avaliar os fatores associados ao consumo diário de refrigerantes, doces e frituras, realizou-se análise multivariável e hierarquizada, por regressão de Poisson, com variáveis sociodemográficas no primeiro nível hierárquico, comportamentais no segundo e relacionadas ao padrão alimentar no terceiro. O consumo de refrigerantes, doces ou frituras em pelo menos uma vez por semana foi referido por 90,9%, 95,4% e 89,6% dos adolescentes, respectivamente. As prevalências correspondentes ao consumo diário destes alimentos foram 30,2%, 42,0% e 28,3%. O consumo diário de doces foi 21% maior entre as meninas e 25% maior entre adolescentes que consumiram arroz e feijão diariamente. Em relação às frituras, as meninas referiram um consumo 37% maior do que os meninos. Adolescentes que consumiram carnes diariamente, apresentaram um consumo diário de frituras 43% maior. O consumo de refrigerantes, doces e frituras entre os adolescentes caruaruenses mostrou-se elevado e apresentou um padrão de consumo homogêneo para a maioria das variáveis analisadas.

ABSTRACT

A school-based cross-sectional study in 2007 evaluated the prevalence and associated factors of daily consumption of soft drinks, sweets and fried foods among adolescents (15 to 20 years of age) in public schools in Caruaru in the state of Pernambuco. To evaluate the factors associated with the daily consumption of the above foods, a multivariate and hierarchical analysis was conducted using Poisson regression, with social and demographic variables at the first hierarchical level, behavioral variables at the second level and dietary standards at the third level. Consumption of soft drinks, sweets and fried foods at least once a week was declared by 90.9%, 95.4% and 89.6% of the adolescents, respectively. The corresponding prevalence of the daily consumption of these items was 30.2%, 42% and 28.3%. The daily consumption of sweets was 21% higher among girls and 25% higher among adolescents who ate rice and beans daily. With respect to fried foods, girls mentioned 37% greater consumption than boys. Adolescents who consumed meat every day admitted a 43% higher daily consumption of fried foods. The consumption of soft drinks, sweets and fried foods among the adolescents from Caruaru was high and showed a homogeneous consumption standard for most variables analyzed.
