Abstract

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.

  • In this study, mean BMI in boys (18.9 kg/m2) and girls (20.2 kg/m2) was similar to the mean BMI of a representative sample of 12- to 17-year-old boys (21.0 kg/m2) and girls (21.3 kg/m2) from Brazilian cities with more than one hundred thousand inhabitants.

    “In the sample of this study, mean BMI in boys (18.9 kg/m2) and girls (20.2 kg/m2) was similar to the mean BMI of a representative sample of 12- to 17-year-old boys (21.0 kg/m2) and girls (21.3 kg/m2) from the Brazilian cities with more than one hundred thousand inhabitants (53).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
