ObjectiveTo describe and compare the nutritional status of adolescents using three criteria for nutritional status classification (Conde & Monteiro, International Obesity Task Force - IOTF and Word Health Organization - WHO), to analyze the correlation between these three criteria as for the overweight proportion, and to investigate whether factors associated with overweight and obesity differ among the three criteria.MethodsDemographic (gender, age, geographic area) and anthropometric (body weight, height) variables were measured in 33.728 adolescents aged 11 to 17 years. The following criteria were investigated: IOTF (2000); Conde & Monteiro (2006); and WHO (2007).ResultsThe overall overweight prevalence was 20.6% for the Conde & Monteiro criteria; 15.3% for the IOTF criteria and 20.1% for the WHO criteria. Both for boys and girls, the estimated overweight prevalence using the Conde & Monteiro and WHO criteria were higher than that using the IOTF criteria. Higher concordance was found between the Conde & Monteiro (2006) and WHO (2007) criteria for all age groups. Regarding associated factors, similar associations were found for the three criteria for higher BMI classification: being male, 11–12 and 13–14 years of age and living in the Midwestern, Southeastern and Southern regions of Brazil.ConclusionThe criteria for BMI classification estimate overweight prevalence in a different way, and the criteria proposed by Conde & Monteiro resulted in higher prevalence in both sexes. Higher concordance between the Conde & Monteiro and WHO criteria was found for all age groups. The groups most vulnerable to showing overweight and obesity for the three criteria for BMI classification were males, age 11–12 and 13–14 years, and living in the Midwestern, Southeastern and Southern regions of Brazil. Overweight and obesity are considered a public health problem prevalent among adolescents in Brazil, regardless of the criteria adopted.

“…These differences among classification criteria can be explained by the sociocultural differences of each population in relation to the cutoff point, since IOTF criteria used a population of six countries: Brazil, Hong Kong, England, the Netherlands, Singapore and the United States 9 . The WHO classification was developed from data of American adolescents in the age group of 5 to 19 years of age 11 .The Conde and Monteiro criteria were constructed from data of Brazilian adolescents (2-19 years old) 10 . Lifestyle, economic level and sexual maturation are factors that differentiate populations of each country and that may influence the growth curves and, consequently, the cutoff points for BMI 7 .…”

“…BMI was categorized as low weight, normal weight, overweight and obese according to cutoff points of the International Obesity Task Force (IOTF) 8 , Conde and Monteiro 10 , and the World Health Organization (WHO) 11 . Cutoff points vary according to the age and sex of adolescents.…”

“…In this perspective, body mass index (BMI) has been a method used to assess weight status and health risk in children and adolescents 8 . Some criteria have been proposed with the purpose of establishing BMI cutoff points for children and adolescents 9,10,11 . However, studies have pointed out differences in the prevalence of overweight and obesity among BMI classification criteria 12,13,14,15 .…”

“…The importance of this investigation should be highlighted, since most studies have investigated the prevalence of "overweight" (overweight and obesity) as a single weight status, grouping both categories (overweight + obesity 11,12 ), but it is necessary to investigate them separately because prevalence, associated factors, and agreement among methods can be differentiated between the classification of overweight and obese.…”

-Aim:To estimate the prevalence of the classifications of overweight and obesity in adolescents according to three criteria for nutritional status classification (Conde & Monteiro, International Obesity Task Force -IOTF and Word Health Organization -WHO), and to investigate whether sociodemographic factors associated with overweight and obesity differ among the three criteria. Method: cross-sectional study with 1,132 adolescents (14-19 years old) living in Brazil. Body Mass Index (BMI) was classified according to three criteria for nutritional status. A self-administered questionnaire was used to collect sociodemographic information. Sexual maturation was measured by self-reported Tanner stage ratings. Multinomial logistic regression was used to estimate the Odds Ratio and 95% confidence intervals. Results: The prevalence of the classification "overweight" (from here on referred to simply as "overweight") was 23.1% for WHO; 23.7% for Conde & Monteiro criteria: and 19.2% for IOTF. Both boys and girls aged 17-19 were more likely to be overweight using the WHO and Conde & Monteiro criteria than those using the IOTF criteria. Girls in the postpubertal maturational stage were less likely of being overweight or obese using the three criteria. Conclusion: The three criteria result in different prevalence measures, with WHO and Conde and Monteiro criteria being more approximate in terms of prevalence and correlated factors when compared to IOTF criteria.
