Table 3. Frequency distribution of subjects' characteristics about components of syndrome metabolic .

	Latent class
	C1 (non MetS)	C2 (low risk)	C3 (high risk)	C4 (MetS)
Latent class prevalence	0.384	0.186	0.242	0.187
Item-response probabilities	Probability of a “Yes”*
Waist circumference	0.261	0.992	0.801	0.970
High density lipoprotein	0.038	0.002	0.071	0.589
Triglyceride	0.250	0.418	0.424	0.743
Systolic blood pressure	0.127	0.149	0.992	0.305
Diastolic blood pressure	0.088	0.090	0.860	0.091
Body mass index	0.005	0.957	0.450	0.398
Fasting blood glucose	0.339	0.434	0.409	0.740

Note. The probability of a “No” response can be calculated by subtracting the item-response probabilities shown above from 1.

*Item-response probabilities >.5 in bold to facilitate interpretation.
