Descriptive statistics of participants’ demographic and biomedical characteristics.
Figure 1.
Model 1: Factor structure of the metabolic syndrome.
Age, sex and race covaried; relevant medications excluded. MS – Second-order metabolic syndrome factor; IR – insulin resistance factor; boxes represent indicator variables and circles reflect latent factors. χ2 = 57.51, df = 12, p<0.001, N = 645; CFI = .98, average absolute standardized residuals = .02, RMSEA = .08.
Figure 2.
Model 2: Single second-order factor model: common factor underlying allostatic load parameters.
Age, sex and race covaried; relevant medications excluded. AL – Second-order allostatic load factor; IR – insulin resistance factor; boxes represent indicator variables and circles reflect latent factors. χ2 = 145.05, df = 42, p<0.001, N = 645; CFI = .97, average absolute standardized residuals = .03, RMSEA = .06.
Figure 3.
Model 3: Two second-order factor model: allostatic load and metabolic syndrome factors.
Age, sex and race covaried; relevant medications excluded. MS resid.: Second-order metabolic syndrome factor with allostatic load parameters simulataneously modeled; AL resid.: Second-order allostatic load factor with metabolic syndrome pathways simultaneously modeled; IR – insulin resistance factor; boxes represent indicator variables and circles reflect latent factors. χ2 = 125.00, df = 38, p<0.001, N = 645; CFI = .97, average absolute standardized residuals = .02, RMSEA = .06. Δχ2 (4) = 20.05, p<0.01.
