Correlação e concordância entre indicadores de obesidade central e índice de massa corporal em adolescentes

Abstract

Objective: To assess the performance of central obesity indicators by correlation and agreement considering the body mass index in the nutritional assessment of adolescents according to sex and age. Methods: Cross-sectional census study with 635 adolescents, aged 10-19 years (342 males and 293 females), studying in a public school in Rio de Janeiro, Brazil. Study variables were body mass index (BMI), waist and abdominal circumference, waist-to-hip ratio, waist-to-height ratio, nutritional status, sex and age. Univariate and multivariate analyses adjusted by stratification were developed. Results: Waist and abdominal circumferences and BMI were positively and significantly correlated to sex, age group and nutritional status (p < 0.05). For the waist-to-hip ratio, co-relation variation was also influenced by age (p < 0.05). Waist and abdominal circumferences depended on BMI values in all groups (R 2 = 0.66-0.80, positive β), which did not occur in waistto-hip ratio and waist-to-height ratio. Only the waist circumference showed moderate agreement with BMI (Kappa: 0.41-0.57) in all groups, while for the remaining indicators this agreement ranged from poor to moderate. Conclusions: Among the central obesity indicators analyzed, waist and abdominal circumferences showed the best performances, but waist circumference was the most adequate to be used in addition to BMI in the nutritional assessment of adolescents.

Association between adiposity indicators, metabolic parameters and inflammatory markers in a sample of female adolescents

“…Studies evaluating the distribution of fat in adolescents, with similar results of this study, found a strong association between BMI and WC (r = 0.88-0.91) (17,18) and between TFM and BMI (r = 0.84-0.97) (19,20). Especially in girls, BMI has been a good indicator of adiposity, because in females a greater fat deposition occurs during the pubertal period (21).…”

Estado nutricional de crianças e adolescentes sobreviventes de leucemia linfoide aguda tratados em um Centro de Referência da Região Nordeste do Brasil

“…Estudo desenvolvido por Chiara et al 29 obteve que dentre os indicadores de obesidade central, as circunferências de cintura e de abdô-men apresentaram os melhores desempenhos, destacando-se a CC como mais apropriada para uso complementar ao IMC na avaliação nutricional de adolescentes. Em adição, Almeida et al 30 , com base em estudo sobre sensibilidade e especificidade das tabelas de Freedman et al 18 e Taylor et al 28 , sugerem que se considere a referên-cia de Taylor et al 28 para triagem, e a de Freedman et al 18 para uso clínico/ambulatorial, sendo possível o seu emprego em substituição a dosagens de custo mais elevado.…”

Indicators of Adiposity Associated With Low Body Esteem in Adolescents

“…Additionally, body mass, height, and waist circumference (WC) measurements were taken in a separate room by a trained team using the protocol recommended by Lohman et al 21 Body esteem (total and appearance, weight, and attribution domains) was the dependent variable, whereas BMI and WC were the independent variables, and adolescents' sex and age group were the covariables. The participants were divided into two age groups according to Chiara et al, 22 taking into account the differences in the process of growth, development, and sexual maturation of boys and girls: younger (boys aged 10 to 14; girls aged 10 to 13) and older (boys aged 15 to 18; girls aged 14 to 18) age groups.…”
