Abstract

Objective: To assess the association between the presence of public outlets selling fruits and vegetables and the regular intake of these foods by adolescents from public schools in the city of Curitiba, Paraná, Brazil.

Methods: Data collection was carried out by a questionnaire answered by the adolescents. Regular intake was defined as eating fruits and vegetables five or more times a week. Environmental data were obtained by assessing the availability and prices of fruits and vegetables traded in public outlets within a 1.6-km radius from 30 randomly selected public schools.

Results: A total of 1,232 students from 30 public schools participated in the study. 43.4% of the adolescents reported a regular intake of fruits; 67.0% of them reported a regular intake of vegetables. In the schools, fruit intake ranged from 26.8 to 68.0%, and the vegetables intake ranged from 54.8 to 82.2%. A total of 22 schools had fruit and vegetables being traded in their surroundings. Regular intake of vegetables was positively correlated with their variety (r=0.82; p=0.007). The Moran's local index indicated low fruit intake in a high-supply region; in other three regions with low supply, there was a high intake of fruits; and there was a high consumption of vegetables in a high-supply region.

Conclusions: There are differences in the supply of fruits and vegetables of public outlets in the school's surroundings as well as in the distribution of regular intake among regions. The density of public outlets and the variety were both associated with greater intake of fruits and vegetables among adolescents of public school.

Objetivo:: Avaliar a associação entre presença de equipamentos públicos de comércio de frutas e hortaliças com seu consumo regular por adolescentes de escolas públicas de Curitiba, Paraná.

Métodos:: Informações dos adolescentes foram coletadas por meio de questionário. Considerou-se como regular o consumo de frutas e hortaliças cinco ou mais vezes na semana. Foram incluídos dados do ambiente obtidos por auditagem de equipamentos públicos de venda de frutas e hortaliças no raio de 1,6 km do entorno de 30 escolas estaduais aleatoriamente sorteadas, no qual foram avaliados a disponibilidade e os preços desses alimentos.

Resultados:: Participaram do estudo 1.232 alunos de 30 escolas estaduais. O consumo regular de frutas foi referido por 43,4% e de hortaliças por 67,0% dos adolescentes. Nas escolas, o consumo de frutas variou entre 26,8 e 68,0% e o de hortaliças entre 54,8 e 82,2%; 22 escolas contavam com oferta de frutas e hortaliças no entorno. O consumo regular de hortaliças esteve correlacionado positivamente com a sua variedade (r=0,82; p=0,007). O índice de Moran local indicou baixo consumo de frutas em uma regional de alta oferta e, em outras três, alto consumo de frutas e hortaliças para baixa oferta e alto consumo de hortaliças em uma regional de alta oferta.

Conclusões:: Existem diferenças na oferta de frutas e hortaliças dos equipamentos públicos no entorno escolar e na distribuição do consumo regular entre as regionais. Características relacionadas à densidade de equipamentos de comércio e à variedade estiveram associadas ao maior consumo de frutas e hortaliças entre os adolescentes de escolas públicas.
