title: [Relationship between serum N-terminal pro-brain natriuretic peptide and metabolic syndrome: a cross-sectional study].
abstract: OBJECTIVE
  To explore the relationship between serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and metabolic syndrome (MS).
  
  
  METHODS
  A total of 1323 Beijing residents (559 male) were investigated. MS was defined by the modified 2004 Chinese Diabetes Society criteria and 439 cases were diagnosed as MS according to this criteria. Multivariate logistic regression analysis was used to estimate the odds ratios (OR) of MS. Multiple linear regression analysis was performed to analyze the association between NT-proBNP and characteristic variables.
  
  
  RESULTS
  NT-proBNP was significantly lower in MS group compared to non-MS group [32.51 (29.17, 36.14) ng/L vs.38.55 (35.73, 41.50) ng/L, P = 0.012] after adjusted for age and gender. NT-proBNP level decreased with the presence of MS components (from 0 to 4 or 5) (45.92, 37.24, 35.40, 31.55 and 33.65 ng/L respectively, P = 0.043 for linear trend). Among the components, groups with larger waist circumference, higher fasting glucose and triglycerides were associated with lower NT-proBNP level. After adjustment for potential confounders, compared with the lowest NT-proBNP quartile, the adjusted odds ratio of the second, third and fourth quartile for having MS were 0.782 (95%CI: 0.544 - 1.122, P > 0.05), 0.709 (95%CI: 0.489 - 1.028, P > 0.05), 0.604 (95%CI: 0.405 - 0.900, P < 0.05), respectively. Multiple linear regression analysis showed that female gender (β = 0.248, P < 0.001), age (β = 0.167, P < 0.001), systolic blood pressure (β = 0.154, P < 0.001) were positively related to NT-proBNP level while waist circumference (β = -0.082, P = 0.004), diastolic blood pressure (β = -0.085, P = 0.015), triglycerides (β = -0.101, P < 0.001), total cholesterol (β = -0.078, P = 0.004), eGFR (β = -0.150, P < 0.001) were negatively correlated to NT-proBNP level.
  
  
  CONCLUSIONS
  In this cohort, higher serum NT-proBNP concentration is associated with lower incidence of metabolic syndrome.
