Exploring the associations between systemic inflammation, obesity and healthy days: a health related quality of life (HRQOL) analysis of NHANES 2005–2008

Table 2 Relationship of Physical and Mental Healthy Days to BMI and CRP levels

Model	Dependent Variable	Parameter	OR (95% CI)
Model 1	HSQ470 (physical)	(Intercept)	0.06 (0.04,0.09)
		overweight	1.06 (0.76,1.47)
		obese	1.59 (1.15,2.21)
Model 2	HSQ480 (mental)	(Intercept)	0.06 (0.05,0.09)
		overweight	1.20 (0.86,1.68)
		obese	1.25 (0.89,1.75)
Model 3	HSQ470 (physical)	(Intercept)	0.06 (0.04,0.07)
		elevated CRP	1.61 (1.23,2.12)
		clinically raised CRP	2.45 (1.84,3.26)
Model 4	HSQ480 (mental)	(Intercept)	0.07 (0.05,0.09)
		elevated CRP	1.05 (0.79,1.40)
		clinically raised CRP	1.66 (1.26,2.19)
Model 5	HSQ470 (physical)	(Intercept)	0.05 (0.04,0.07)
		overweight	0.98 (0.70,1.35)
		obese	1.26 (0.92,1.74)
		elevated CRP	1.51 (1.14,2.0)
		clinically raised CRP	2.21(1.55,3.16)

Results include estimates of odds ratio (OR) and corresponding 95% confidence intervals under different models indexed by varying dependent variables. The OR is interpreted as the relative changes in odds for physical (HSQ470 > 15 days) or mental (HSQ480 > 15 days) unhealthy days upon changes in the categories of the explanatory variables (BMI and/or CRP)
Data was analyzed using sampling weighted generalized linear models (logistic) as described under Methods. Model specifications are as follows: Model 1, HSQ470 vs. BMI; Model 2, HSQ480 vs. BMI; Model 3, HSQ470 vs. CRP; Model 4, HSQ480 vs. CRP; Model 5, HSQ470 vs. BMI and CRP
