Resumo: This article aims to evaluate the joint and separate association between abdominal and general adiposity indicators and mortality. Data was collected from 1,366 older adults in the Bambuí Cohort Study of Aging with complete information for all variables of interest. The outcome variable was all-cause time until death; exposure variables were a body shape index (ABSI), waist circumference (WC), waist-to-height ratio (WHtR) and body mass index (BMI), assessed at the beginning of the study, and at the 3rd, 5th and 11th year of follow-up. Association between the quartiles of anthropometric indicators and mortality was calculated using an extended Cox proportional hazards model and adjusted for socioeconomic and behavioral confounding factors. Older adults in the 4th ABSI quartile had a higher risk of mortality regardless of BMI (1.27; 95%CI: 1.01-1.58), but this association was not observed in sensitivity analyses. Older adults in the 2nd, 3rd and 4th BMI quartiles had a lower risk of mortality, even when adjusted for WC or ABSI. WC and WHtR showed no association consistent with all-cause mortality after adjustment for confounding factors. Considering the loss of significance in the sensitivity analyses, ABSI’s predictive capacity for mortality is still weak. Thus, adopting ABSI in clinical practice or in epidemiological surveys, in conjunction or replacing BMI and WC, requires more in-depth studies.

Los datos se recogieron de 1.366 adultos mayores en el estudio de Cohorte Ancianos de Bambuí, Brasil, con información completa para todas las variables de interés. El resultado de la variable fue por cualquier causa hasta la muerte; las variables de exposición fueron índice de forma corporal (a body shape index - ABSI por sus siglas en inglés), circunferencia de cintura (WC), proporción cintura-altura (WHtR) e índice de masa corporal (BMI), evaluados al principio del estudio, y en el 3º, 5º y 11º año de seguimiento. Se calculó la asociación entre los cuartiles de indicadores antropométricos y mortalidad, usando un modelo extendido de Cox de riesgos proporcionales, y ajustado por factores de confusión socioeconómicos y comportamentales. Los adultos más viejos en el 4º cuartil ABSI tuvieron un riesgo mayor de mortalidad, independientemente del BMI (1,27; 95%CI: 1,01-1,58), pero esta asociación no fue observada en los análisis de sensibilidad. Los adultos más viejos en los 2º, 3º y 4º cuartiles de BMI tuvieron un riesgo más bajo de mortalidad, incluso cuando fue ajustado por WC o ABSI. WC y WHtR no mostraron asociación consistente con todas las causas de mortalidad tras el ajuste para factores de confusión. Considerando la pérdida de significación en los análisis de sensibilidad, la capacidad predictiva de ABSI para la mortalidad es todavía débil. De este modo, adoptar ABSI en la práctica clínica o en encuestas epidemiológicas, en conjunción o reemplazando BMI y WC, requiere más estudios en profundidad.O estudo teve como objetivo avaliar a associação isolada e independente entre indicadores de adiposidade abdominal e índice de massa corporal (IMC) e mortalidade. O estudo usou dados de 1.366 idosos que tinham informações completos para todas as variáveis independentes no Estudo de Coorte de Idosos de Bambuí, Brasil. A variável dependente foi o tempo até o óbito por todas as causas, e as variáveis de exposição foram o índice de forma corporal (a body shape index - ABSI), circunferência de cintura (CC), razão cintura/estatura (RCE) e IMC, medidos na linha de base e aos 3º, 5º e 11º anos de seguimento. A associação entre os quartis de indicadores antropométricos e a mortalidade foi investigada usando um modelo estendido de riscos proporcionais de Cox ajustado por fatores de confusão socioeconômicos e comportamentais. Os idosos do 4º quartil do ABSI mostraram maior risco de mortalidade, independentemente de IMC (1,27; IC95%: 1,01-1,58), mas a associação não foi mantida nas análises de sensibilidade. Os idosos do 2º, 3º e 4º quartis de IMC mostraram risco menor de mortalidade, associação esta que foi mantida após ajustar para CC ou ABSI. Por outro lado, a CC e a RCE não mostraram associações consistentes com a mortalidade geral depois de ajustar para fatores de confusão. As análises mostraram que a capacidade preditiva do ABSI para mortalidade ainda é fraca, considerando a perda de significância nas análises de sensibilidade. Portanto, a possibilidade de adoção do ABSI na prática clínica ou em inquéritos epidemiológicos para complementar ou substituir o IMC e CC ainda precisa ser explorada com maior profundidade em estudos futuros.Reports in Public HealthCadernos de Saúde Pública2021-01-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/7585Reports in Public Health; Vol. 37 No. 1 (2021): JanuaryCadernos de Saúde Pública; v. 37 n. 1 (2021): Janeiro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/7585/16878https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/7585/16879Mary Anne Nascimento-SouzaJuliana Vaz de Melo MambriniSérgio Viana PeixotoMaria Fernanda Lima-Costainfo:eu-repo/semantics/openAccess2024-03-06T15:30:02Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/7585Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:08:43.801316Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
