Resumo: | OBJECTIVE To describe the response rate and characteristics of people who either took part or not in from the Study of Cardiovascular Risks in Adolescents (ERICA) , according to information subsets. METHODS ERICA is a school-based, nation-wide investigation with a representative sample of 12 to 17-year-old adolescents attending public or private schools in municipalities with over 100,000 inhabitants in Brazil. Response rate of eligible subjects were calculated according to macro-regions, sex, age, and type of school (public or private). We also calculated the percentages of replacement schools in comparison with the ones originally selected as per the sample design, according to the types of schools in the macro-regions. The subjects and non-subjects were compared according to sex, age, and average body mass indices (kg/m2). RESULTS We had 102,327 eligible adolescents enrolled in the groups drawn. The highest percentage of complete information was obtained for the subset of the questionnaire (72.9%). Complete information regarding anthropometric measurements and the ones from the questionnaire were obtained for 72.0% of the adolescents, and the combination of these data with the 24-hour dietary recall were obtained for 70.3% of the adolescents. Complete information from the questionnaire plus biochemical blood evaluation data were obtained for 52.5% of the morning session adolescents (selected for blood tests). The response percentage in private schools was higher than the one in public schools for most of the combination of information. The ratio of older and male adolescents non-participants was higher than the ratio among participants. CONCLUSIONS The response rate for non-invasive procedures was high. The response rate for blood collection – an invasive procedure that requires a 12-hour fasting period and the informed consent form from legal guardians – was lower. The response rate observed in public schools was lower than in the private ones, and that may reflect lower school frequency of registered students. |

OBJETIVO Descrever o percentual de resposta e características de participantes e não-participantes no Estudo de Riscos Cardiovasculares em Adolescentes (ERICA) segundo subconjuntos de informações. MÉTODOS O ERICA é um inquérito de base escolar de abrangência nacional com amostra representativa de adolescentes, de 12 a 17 anos de idade, que estudam em escolas públicas ou privadas de municípios com mais de 100 mil habitantes de todo o Brasil. Foram calculadas frequências de participação (de elegíveis) por macrorregiões, sexo, idade, e tipo de escola (pública ou privada). Foram calculados também os percentuais de escolas substitutas das selecionadas na origem do desenho amostral, de acordo com o tipo de escola nas macrorregiões. Os participantes e não-participantes foram comparados segundo sexo, idade e média de índice de massa corporal (kg/m2). RESULTADOS Estavam cadastrados nas turmas sorteadas 102.327 adolescentes elegíveis. O maior percentual de informações completas foi obtido para o subconjunto do questionário (72,9%). Informações completas das medidas antropométricas e do questionário foram obtidas em 72,0% dos adolescentes, e a combinação dessas informações com recordatório alimentar de 24h, em 70,3%. Informações completas do questionário mais avaliação bioquímica do sangue foram obtidas em 52,5% dos adolescentes do turno da manhã (elegíveis para exame de sangue). O percentual de resposta nas escolas privadas foi maior do que a das escolas públicas para a maioria das combinações de informações. A proporção de adolescentes não participantes do sexo masculino e mais velhos foi maior do que entre os participantes. CONCLUSÕES O percentual de resposta para procedimentos não invasivos foi elevado. Para a coleta de sangue, procedimento invasivo, com necessidade de jejum de 12 horas e de consentimento escrito dos responsáveis, a participação foi menor. O percentual de participação observado nas escolas públicas foi menor do que nas particulares, podendo refletir menor frequência escolar dos alunos cadastrados. Universidade de São Paulo.
