Approximately 85,000 students were assessed in public and private schools. Brazil is a continental country with a heterogeneous population of 190 million living in its five main geographic regions (North, Northeast, Midwest, South and Southeast). ERICA is a pioneering study that will assess the prevalence rates of cardiovascular risk factors in Brazilian adolescents using a sample with national and regional representativeness. This paper describes the rationale, design and procedures of ERICA. (Continued on next page) * Correspondence:

This was a cross-sectional, school-based study with adolescents 12 to 17 years of age. Obesity was classified by body mass index based on World Health Organization criteria, according to age and sex. The association between obesity and sharing lunch and supper with parents/guardians (never, sometimes, almost every day, and every day) was analyzed according to crude and sex- and age-adjusted prevalence ratios. A total of 71,740 adolescents were assessed. Of these, 48% and 60% of girls and 56% and 65% of boys, respectively, shared lunch and supper every day or nearly every day. Boys who shared lunch and supper with their parents/guardians nearly every day and every day showed lower prevalence of obesity. Stratified by age bracket, only younger boys...

METHODS We evaluated 37,504 adolescents who were participants in the Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional, school-based, national study. The adolescents, aged from 12 to 17 years, lived in cities with populations greater than 100,000 inhabitants. The sample was stratified and clustered into schools and classes. The criteria set out by the International Diabetes Federation were used to define metabolic syndrome. Prevalences of metabolic syndrome were estimated according to sex, age group, school type and nutritional status. RESULTS Of the 37,504 adolescents who were evaluated: 50.2% were female; 54.3% were aged from 15 to 17 years, and 73.3% were from public schools. The prevalence of metabolic syndrome was 2.6% (95%CI 2.3-2.9), slightly higher in males and in those aged from 15 to 17 years in most macro-regions. The prevalence was the highest in...

METHODS Data from participants in the Brazilian Study of Cardiovascular Risks in Adolescents (ERICA), which was the first national school-based, cross-section study performed in Brazil were evaluated. The sample was divided into 32 geographical strata and clusters from 32 schools and classes, with regional and national representation. Obesity was classified using the body mass index according to age and sex. Arterial hypertension was defined when the average systolic or diastolic blood pressure was greater than or equal to the 95th percentile of the reference curve. Prevalences and 95% confidence intervals (95%CI) of arterial hypertension and obesity, both on a national basis and in the macro-regions of Brazil, were estimated by sex and age group, as were the fractions of hypertension attributable to obesi...

A determinação da amostra seguiu dois passos, considerando o número de unidades de vacinação e as crianças em cada unidade. Um inquérito nutricional contendo um recordatório alimentar de 24 horas foi aplicado a 921 acompanhantes das crianças menores de um ano. Houve incremento positivo em todas as faixas etárias na modalidade de aleitamento materno exclusivo. Observou-se, ao final dos 180 dias, baixo percentual de crianças em aleitamento materno exclusivo, sendo menos de 5% (em 1999) e de 10% (em 2004). A prevalência do aleitamento materno exclusivo dobrou em cinco anos nas crianças menores de 120 dias, passou de 17,7% para 28,5%. As ações realizadas para promoção do aleitamento materno foram efetivas, porém, insuficientes para a grave s...
