Prevalence of metabolic syndrome in elderly Japanese-Brazilians

Abstract

SummaryBackgroundPrevalence of individuals with a high cardiovascular risk is elevated in elderly populations. Although metabolic syndrome (MS) increases cardiovascular risk, information is scarce on the prevalence of MS in the elderly. In this study we assessed MS prevalence in a population of elderly Japanese-Brazilians using different MS definitions according to waist circumference cutoff values.Material/MethodsWe studied 339 elderly subjects, 44.8% males, aged between 60 to 88 years (70.1±6.8). MS was defined according to criteria proposed by the Joint Interim Statement in 2009. As waist circumference cutoff point values remain controversial for Asian and Japanese populations, we employed 3 different cutoffs that are commonly used in Japanese epidemiological studies: 1) ≥90 cm for men and ≥80 cm for women; 2) ≥85 cm for men and ≥90 cm for women; 3) ≥85 cm for men and ≥80 cm for women.ResultsMS prevalence ranged from 59.9% to 65.8% according to the different definitions. We observed 90% concordance and no statistical difference (p>0.05) in MS prevalence between the 3 definitions. MS diagnosis according to all 3 cutoff values was found in 55.8% of our population, while in only 34.2% was MS discarded by all cutoffs. The prevalence of altered MS components was as follows: arterial blood pressure 82%, fasting glycemia 65.8%, triglyceride 43.4%, and HDL-C levels 36.9%.ConclusionsElderly Japanese-Brazilians present high metabolic syndrome prevalence independent of waist circumference cutoff values. Concordance between the 3 definitions is high, suggesting that all 3 cutoff values yield similar metabolic syndrome prevalence values in this population.

Predictors of Cardiovascular Events in Elderly with Metabolic Syndrome from Rural Northeast China

“…Korean survey of cardiometabolic syndrome reported that there was an increasing trend of metabolic syndrome with elevating ages and with the highest rate among subjects older than 60 years (37.9%) [1]. Similarly, results from the SABE survey claimed that the prevalence of MetS was 66.0% in elderly women and 47.1% in elderly men which was closed to many previous studies [2][3][4]. Previous studies already con rmed that MetS were relatively more prevalent among urban residents when compared with rural residents [5,6].…”

“…In elderly Japanese-Brazilians the MetS prevalence ranged from 59.9% to 65.8% according to the different definitions. The prevalence of altered MetS components was as follows: arterial blood pressure 82%, fasting glycaemia 65.8%, triglycerides 43.4%, and HDL-C levels 36.9% [25].…”

Gender discrepancies in predictors for newly onset cardiovascular events and metabolic syndrome in elderly patients from rural China

“…A Korean cardiometabolic syndrome survey reported an increasing case of metabolic syndrome with an increase in age, with the highest rate among subjects older than 60 (37.9%) ( 2 ). The National Survey of Health, Wellbeing, and Aging survey also showed that the prevalence of MetS was 66.0% in older women and 47.1% in older men ( 3 – 5 ) and is relatively more prevalent among urban than rural residents ( 6 , 7 ). However, data from our study indicated that the prevalence of MetS among general rural residents was 39.0%, which was significantly higher than many other rural Chinese areas, such as Hanzhong (15.1%), Nantong (23.3%), and Xinjiang (14.43%) ( 8 – 10 ).…”
