title: Metabolic syndrome in Iranian elderly.
abstract: BACKGROUND
  This study aimed to compare Iranian elderly with the middle-aged population in terms of the prevalence of metabolic syndrome and its components.
  
  
  METHODS
  This cross-sectional study was conducted using the data from the third phase of the Isfahan Healthy Heart Program. Male and female residents of Isfahan over 19 years of age were selected by multistage cluster random sampling. A questionnaire including demographic characteristics, health status, medical history, medications used, as well as waist circumference, weight, height, and systolic and diastolic blood pressures was completed for all participants. Fasting blood samples were obtained from all subjects and examined for fasting blood sugar and lipid profile. T-test and Mann-Whitney test were used for quantitative data and chi-square test was performed for qualitative data.
  
  
  RESULTS
  The prevalence of metabolic syndrome in individuals aged over 60 years was significantly higher than those under 60 (49.5% vs. 17.5%, respectively; P < 0.001). Metabolic syndrome was also more prevalent among elderly females than in males (59.2% vs. 39.8%, respectively; P < 0.005). Some anthropometric measures such as height, body mass index, abdominal circumference, waist-hip ratio, and waist-to-height ratio were significantly different in men and women below 60 years in comparison with those over 60 years (P < 0.05). Moreover, there were significant differences in most studied parameters between the elderly and non-elderly women (P < 0.001).
  
  
  CONCLUSIONS
  This study showed that metabolic syndrome has a relatively high prevalence in Iranian elderly people, especially in elderly women. Therefore, early diagnosis and management of the complication are recommended among this high-risk group to avoid the subsequent complications.
