0407/2017 - Indicadores de obesidade: Capacidade preditiva para síndrome metabólica em adultos quilombolas. Obesity indicators: Predictive capacity for metabolic syndrome in quilombola (inhabitants of black communities) adults.
O objetivo deste estudo foi avaliar a capacidade preditiva da síndrome metabólica (SM) por diferentes indicadores de obesidade (IO) em adultos quilombolas. Estudo transversal com amostra representativa de 850 adultos (18 à 92 anos de idade) quilombolas residentes na microrregião geográfica de Guanambi/Bahia. Foram construídas curvas Receiver Operating Characteristic (ROC) entre os IO (percentual de gordura - %G; índice de adiposidade corporal – IAC; índice de massa corporal – IMC) e a SM. O equilíbrio entre sensibilidade e especificidade definiu os melhores pontos de corte preditores da SM pelos IO. Os três IO apresentaram capacidade preditiva para SM (curva ROC significativamente >0,5). Entre as mulheres, o %G apresentou área sob a curva ROC (0,69 - IC95%: 0,65:0,73) significativamente maior que os demais IO. Entre os homens as áreas do %G e do IMC foram iguais (0,81 - IC95%: 0,76:0,85) e maiores que a do IAC. Os melhores pontos de corte dos IO para identificar a presença da SM respectivamente em mulheres e homens foram: 24,97 e 25,36 kg/m² para IMC, 34,30 e 26,14% para IAC e 37,7 e 23,8% para %G. Os IO testados são válidos para rastrear a SM em adultos quilombolas a partir da utilização dos pontos de corte específicos para a população estudada.

Abstract:
The objective of this study was to evaluate the predictive capacity of metabolic syndrome (MS) by different obesity indicators (OI) in quilombolas (inhabitants of black communities) adults. It is a cross-sectional study with a representative sample of 850 adult quilombolas (18 to 92 years old) residing in the geographic micro-region of Guanambi, Bahia, Brazil. Receiver Operating Characteristic (ROC) curves were constructed between the IO (Body Fat Percentage (BFP), Body Adiposity Index (BAI), Body Mass Index (BMI) and MS. The balance between sensitivity and specificity defined the best predictive cutoff points of MS by OI. The three OIs presented predictive capacity for MS (ROC curve significantly> 0.5). Among women, the BFP showed a significantly higher area under the ROC curve (0.69 - 95% CI: 0.65: 0.73) than the other OIs. Among men, the BFP and BMI areas were the same (0.81 - 95% CI: 0.76: 0.85) and higher than the BAI. The best OI cutoff points to identify the presence of MS, respectively, in women and men were: 24.97 and 25.36 kg/m² for BMI, 34.30 and 26.14% for BAI and 37.7 and 23.8% for BFP. The IOs tested are valid for screening method for MS in quilombola adults based on the use of specific cutoff points for the studied population.
