RESUMEN
OBJETIVOS: Avaliar o comportamento alimentar para frutas e hortali�as de adolescentes em vulnerabilidade social.M�TODOS: Estudo transversal com adolescentes assistidos por dois projetos sociais selecionados por amostragem de conveni�ncia em Chapec�, estado de Santa Catarina. Aplicou-se Recordat�rio de 24 horas para analisar o consumo de frutas e hortali�as e um algoritmo espec�fico para investigar a autopercep��o sobre a qualidade do consumo e os est�gios de mudan�a de atitude alimentar. Os dados foram analisados com o Statistical Package for Social Sciences v.17.0, por estat�stica descritiva e inferencial, adotando-se n�vel de signific�ncia de 5%.RESULTADOS: Participaram do estudo todos os 120 adolescentes assistidos pelos projetos sociais selecionados, 59 meninos e 61 meninas, com idade m�dia de 12,9�1,92 anos. O consumo m�dio (por��es/dia) foi 2,14�1,79 para frutas e 0,67�0,68 para hortali�as. Meninas consumiam mais hortali�as (p=0,047); 52 (43,3%) adolescentes consideravam ter consumo saud�vel de frutas, entretanto somente 24 (46,2%) destes tinham consumo adequado; 61 (50,9%) afirmaram consumo saud�vel de hortali�as, enquanto apenas dois (3,3%) destes tinham consumo adequado. Os que consideravam ter consumo saud�vel consumiam mais frutas (p=0,001). Sobre o est�gio de mudan�a, as meninas foram maioria em contempla��o e decis�o, e os meninos em pr�-contempla��o e a��o (p=0,014). O consumo de frutas apresentou correla��o positiva significativa (rs=0,302; p=0,001) com os est�gios de mudan�a, sendo maior nos est�gios mais avan�ados.CONCLUS�ES: O consumo de frutas e hortali�as foi inferior �s recomenda��es, situa��o agravada pela autopercep��o distorcida sobre a qualidade deste consumo e pela vulnerabilidade social. Os aspectos subjetivos do comportamento alimentar evidenciaram a predomin�ncia de adolescentes com consumo inadequado destes alimentos que n�o consideram a possibilidade de mudan�a de atitude alimentar.
Aims: To assess dietary behavior to fruit and vegetable intake of adolescents in social vulnerability.Methods: Cross-sectional study with adolescents assisted by two social projects selected by convenience sampling in Chapeco, Santa Catarinastate, Brazil. A 24-hour dietary recall was applied to analyze the consumption of fruits and vegetables, and a specific algorithm to investigateperception about the quality of consumption and the stages of change in eating attitude. Data were analyzed with Statistical Package for SocialSciences v.17.0, using descriptive and inferential statistics, with a significance level of 5%.Results: All the 120 adolescents assisted by the selected social projects, 59 boys and 61 girls, mean age 12.9�1.92 years, participated in thestudy. Average consumption (servings/day) was 2.14�1.79 for fruits and 0.67�0.68 for vegetables. Girls consumed more vegetables (p=0.047);43.3% of teens thought they have healthy intake of fruit, but only 46.2% of these had adequate intake; 50.9% said to have healthy vegetableconsumption, while only 3.3% of these had adequate intake. Those who thought to have healthy intake, consumed more fruit (p=0.001). On thestage of change, most girls were in contemplation and decision, and most boys in pre-contemplation and action (p=0.014). The consumptionof fruits showed a significant positive correlation (rs=0.302, p=0.001) with the stages of change, being higher in more advanced stages.Conclusions: Consumption of fruits and vegetables was lower than recommendations, situation exacerbated by distorted perception aboutquality of consumption and by social vulnerability. Subjective aspects of feeding behavior revealed the predominance of adolescents withinadequate intake of these foods that do not consider the possibility of changing food attitude.
