title: The investigation of the correlation between metabolic syndrome and Chinese medicine constitution types in senior retired military personnel of the People's Liberation Army.
abstract: OBJECTIVE
  To investigate the incidence of metabolic syndrome (MS) and the distribution of constitutional pattern in elderly retired personnel of the People's Liberation Army.
  
  
  METHODS
  Adopting the method of cross-sectional field investigation, from June to December in 2008, the investigation questionnaires were completed by the aged over 60 and collected from 69 military retired residences in the 4 cities of Shanghai, Nanjing, Hangzhou and Qingdao. Other data, including demographic characteristics, physiological characteristics, life style and former medical history, were collected and analyzed. The statistical analysis for the database was drawn up by the software Epidata 3.0.
  
  
  RESULTS
  A total of 4,502 people were included in this study, and 35.3% of them were diagnosed with MS. There was no obvious difference in mobility among ages (60 to 69, 70 to 79 and over 80, P>0.05). Referring to the MS patients in the 70s age group, both the phlegm-dampness and dampness-heat constitutional types were evidently higher than those in the 60s age group (P=0.019, P=0.008); while MS patients in 80s and older showed a significantly lower incidence of dampness-heat constitution than those in the 60s (P=0.00); and ql-deficiency constitution was obviously higher in the 80s age group than those in the other two groups (P=0.00). The top 3 constitutions in MS people were, respectively, phlegm-dampness, dampness-heat and qi-deficiency constitution; while in non-MS people, the top 3 constitutions were gentleness, qi-deficiency and phlegm-dampness. When the patient's body mass index (BMI) was more than 25 kg/m(2), the rate of phlegm-dampness and dampness-heat constitution significantly increased, while the rate of qi-deficiency constitution declined; the discrepancy was significant (P=0.00).
  
  
  CONCLUSIONS
  The prevalence rate of MS in military senior people was 35.3%, which did not vary among the three age groups. Phlegm-dampness, dampness-heat and qi-deficiency constitution were the three dominant constitutional types seen in the MS patients. The distribution of constitution formation was different in MS people and non-MS people. For different dimensions of BMI, the proportion of each kind of constitutions was varied.
