Table 5.

Multivariable rate ratios, 95% confidence intervals, and p-values of incident diabetes by baseline periodontal disease (PD) status, modified by baseline obesity status.

	Obesity (BMI ≥ 30)			No Obesity (BMI < 30)
	Rate Ratio	95% CI	p-value	Rate Ratio	95% CI	p-value
Periodontal disease: Moderate/severe	2.40	1.79, 3.21	< 0.0001	1.18	0.82, 1.69	0.38
Periodontal disease: Mild/none	2.70	2.04, 3.58	< 0.0001	1.0 (ref)	--	--

Notes:

Model covariates included gender, age, Hispanic ethnicity, years spent in the United States, education, income, time since last dental visit, health insurance status, cigarette use, and log of C-reactive protein, in addition to indicator variables for the interaction of periodontal disease and obesity.
