Assessment of calcium intake by adolescents

Objective: To evaluate the daily calcium intake of adolescents in schools from Chapeco, Santa Catarina, Southern Brazil, to check if calcium intake is in accordance with the Dietary Reference Intakes (DRI), and to investigate variables associated with daily calcium intake. Methods: Cross-sectional study approved by the Institutional Review Board and developed in 2010. Students of the 8 th grade completed questionnaires with personal data and questions about the calcium-rich foods intake frequency. In order to compare students with adequate (1300mg) or inadequate intake of calcium/day (<1300mg), parametric and nonparametric tests were used. Results: A total of 214 students with a mean age of 14.3±1.0 years were enrolled. The median daily calcium intake was 540mg (interquartile range – IQ: 312–829mg) and only 25 students (11.7%) had calcium intake within the recommendations of the DRI for age. Soft drink consumption ≥3 times/week was associated with a lower intake of calcium. Conclusions: Few students ingested adequate levels of calcium for the age group. It is necessary to develop a program to encourage a greater intake of calcium-rich foods in adolescence.OBJECTIVE: To evaluate the daily calcium intake of adolescents in schools from Chapecó, Santa Catarina, Southern Brazil, to check if calcium intake is in accordance with the Dietary Reference Intakes (DRI), and to investigate variables associated with daily calcium intake.

Alunos de oitava serie responderam questionarios com dados pessoais e perguntas sobre a frequencia da ingestao de alimentos ricos em calcio. Para comparar escolares com ingestao adequada (1300mg) ou inadequada de calcio/dia (<1300mg), utilizaram-se testes parametrico e nao parametrico.RESULTADOS: Avaliaram-se 214 alunos com media de idade de 14,3±1,0 anos. A mediana de consumo diario de calcio foi de 540mg (intervalo interquartil - IQ: 312-829mg) e somente 25 alunos (11,7%) apresentaram ingestao de calcio dentro das recomendacoes das DRI para a idade. O consumo de refrigerante ≥3 vezes/semana mostrou-se associado a menor consumo de calcio.CONCLUSOES: Poucos alunos ingeriam calcio em niveis adequados para a faixa etaria, o que torna necessario desenvolver um programa de incentivo a maior ingestao de alimentos ricos em calcio.
