Prevalence of Metabolic Syndrome in Elderly and Agreement among Four Diagnostic Criteria

Abstract

BackgroundMetabolic syndrome (MS) is an aggregation of risk factors that increase the incidence of cardiovascular events and diabetes mellitus (DM). Population aging is accompanied by higher prevalence of MS, which varies depending on the population studied and the diagnostic criteria used. ObjectiveTo determine prevalence of MS in the elderly using four diagnostic criteria and agreement between them. MethodsCross-sectional study on 243 patients older than 60 years (180 women) in Niterói, RJ. They were evaluated by clinical examination, fasting glucose, fasting insulin, lipid profile and anthropometric measurements - weight, height, waist circumference and waist/hip ratio. Prevalence of MS was estimated by World Health Organization (WHO) modified, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria. ResultsPrevalence was high with the four criteria WHO (51.9%), NCEP-ATPIII (45.2%), IDF (64.1%) and JIS (69.1%), and agreement between criteria by kappa was moderate in almost all comparisons WHO vs. IDF (k = 0.47;95% confidence interval (CI), 0.35 to 0.58); WHO vs. NCEP-ATPIII (k = 0.51; 95% CI, 0.40 to 0.61); WHO vs. JIS (k = 0.45; 95% CI, 0.33 to 0.56); IDF vs. NCEP-ATPIII (k = 0.55; 95% CI, 0.45 to 0.65) and NCEP-ATPIII vs. JIS (k = 0.53; 95% CI, 0.43-0.64), except between IDF vs. JIS (K = 0.89;95% CI, 0.83 to 0.95), which was considered good. ConclusionPrevalence of MS was high with the four diagnostic criteria, mainly by JIS. There was good agreement between JIS and IDF criteria and moderate among the others.

Predictive capacity of indicators of adiposity in the metabolic syndrome in elderly individuals

“…A Brazilian study of 243 elderly individuals (whose average age was 71±7 years for women and 70±7 years for men), predominantly female (74.0%), conducted in Rio de Janeiro, revealed a higher overall prevalence of MetS using the same criterion diagnosis, 69.1%. In the present study, the prevalence of MetS among men and women was similar, but in comparison, the prevalence among men was higher than that found in the present study, 69.8%, and similar in relation to the female subjects, 68.9% [19]. Research in Taiwan evaluated a cohort of 18,916 elderly individuals divided into three age subgroups using the Joint Interim Statement (JIS) criterion.…”

Síndrome metabólica em idosos da atenção terciária em Porto Alegre, Rio Grande do Sul: associação com o Índice de Alimentação Saudável

“…São previstas taxas de crescimento de mais de 4% ao ano no período de 2012 a 2022, devendo o contingente de idosos no Brasil atingir 41,5 milhões, em 2030 [2]. À medida que envelhecem, as pessoas tornam-se mais propensas a experimentar multimorbidades [1], em geral doenças crônicas não-transmissíveis (DCNT) [3,4], entre elas as doenças cardiovasculares [5][6][7].…”

Síndrome metabólica e estado nutricional de idosos cadastrados no HiperDia

“…No presente estudo, a prevalência de SM foi maior que a encontrada em outros trabalhos com idosos brasileiros, que compararam os critérios do NCEP-ATP III com outros critérios diagnósticos de SM, e apresentaram boa concordância entre os métodos [10,19,20]. No entanto, esta amostra foi composta por indivíduos hipertensos e/ou diabéticos, o que contribuiu para o maior potencial de preencher os critérios diagnósticos de SM [25].…”

“…A prevalência de SM varia bastante de acordo com o perfil da população estudada e do critério diagnóstico empregado [10]. Estudos que utilizaram os critérios recomendados pelo National Cholesterol Education Program's Adult Treatment Panel III (NCEP-ATP III), e adotados pela I Diretriz Brasileira de Diagnóstico e Tratamento da Síndrome Metabólica (I-DBSM) [6], encontraram valores de prevalência variando de 28,1% a 43,5% em idosos norte-americanos [11,12], de 11,3 a 34,3% entre idosos europeus [13][14][15][16] e de 24 a 30,5% em asiáticos [17,18].…”

Seguindo esses mesmos critérios, estudos com idosos brasileiros têm apresentado índices de prevalência de SM que variam de 45,2 a 51,6%, sendo essa prevalência significativamente maior entre as mulheres (45,6 a 73,5% versus 26,5 a 44,4% nos homens) [10,19,20].…”
