Prevalence of metabolic syndrome in an elderly Swedish population
ABSTRACT The prevalence of the metabolic syndrome in different elderly European populations has not been well studied. The aim of this study was to measure the prevalence of metabolic syndrome, as well as its individual components, in an elderly Swedish cohort. A random sample of 778 individuals (372 men and 406 women) was selected from a 70-year-old cohort in the H70 study, a gerontological and geriatric population study carried out in Gothenburg, Sweden. The study included medical and treatment history assessments, laboratory procedures and physical examinations to determine the presence of each of the five components of the metabolic syndrome as defined by the National Cholesterol Education Program Adult Treatment Panel III. Of the 508 adults (243 men and 265 women) included in the study, 22.6% had metabolic syndrome. The prevalence was higher in men (26.3%) than in women (19.2%). One third of the total sample had at least one of the five risk factors for metabolic syndrome. High blood pressure (> or =130/85 mmHg or use of antihypertensive/diuretic medication) was the most prevalent risk factor in both men (68.3%) and women (50.2%), while abdominal obesity was the overall second most common risk factor (27.2% of men and 42.7% of women). The prevalence of high fasting plasma glucose (> or =110 mg/dl or use of antidiabetic medication) was 29.0% in men and 19.1% in women. Metabolic syndrome was prevalent in a significant proportion of this elderly Swedish population, highlighting the underdiagnosis of a condition that is important to treat.

ABSTRACT: The aging of the world's population is a major contributor to the growing prevalence of the cardiometabolic syndrome (CMS) because older persons are more affected by the constellation of cardiovascular risk factors that constitute the syndrome. The prevalence of CMS has been related to the increasing prevalence of obesity, which is growing progressively even among older age groups. Indeed, obesity and aging are 2 overlapping mounting public health problems. It is currently accepted that CMS predicts cardiovascular mortality and/or the development of type 2 diabetes mellitus, and this is also true in studies including older persons. CMS is further complicated by modifications in body composition and fat redistribution during aging; older adults are at higher risk for developing central obesity and sarcopenia or sarcopenic obesity, a condition characterized by an important reduction in lean body mass associated with obesity, linked to an increased production of inflammatory adipokines that may alter insulin sensitivity and muscle mass and strength. A better understanding of the pathophysiologic mechanisms of sarcopenic obesity may help to elucidate the complex relationship between CMS and mortality/morbidity in older adults.Journal of the CardioMetabolic Syndrome 02/2007; 2(3):183-9.
