Association of metabolic syndrome with atherogenic index of plasma in an urban Chinese population: A 15-year prospective study.

BACKGROUND AND AIMS

The metabolic syndrome(Mets) is a multiplex risk factor for atheroselerotie cardiovascular disease. The aims of the study were to assess the association of the Mets with atherogenic index of plasma(AIP) and other atherogenic parameters in an urban Chinese population.

METHODS AND RESULTS

The data were collected in 1992 and then again in 2007 from the same group of 582 individuals(359 men and 223 women) without Mets in 1992. During 15 years' follow-up, AIP was the lipid parameter that was most strongly associated with Mets, with an unadjusted odds ratio of 5.66 (95% CI:1.76-18.23, P = 0.004) in the univariate logistic regression analysis. Multivariate logistic regression analyses also revealed that AIP was an independent risk factor for Mets. AIP significantly predicted Mets in men, with an unadjusted odds ratio of 30.73 (95% CI: 5.62, 168.12 P = 0.012) in a univariate model. Associations remained significant after adjustment for smoking, drinking, physical exercise and components of Mets. The incidences of Mets adjusted for age according to the quartiles of AIP showed a statistical linear trend in men(P for trend = 0.007) rather than in women(P for trend = 0.529).

CONCLUSIONS

AIP might be a strong and independent predictor for Mets in an urban Chinese population. The incidence of Mets increased with AIP elevated in men while not in women.
