Self-reported physical functioning, cardiometabolic health conditions, and health care utilization patterns in Million Veteran Program enrollees with Traumatic Brain Injury Screening and Evaluation Program data

Table 3 Logistic regression results for associations between health outcomes and TBI Screening and Evaluation Program diagnostic groups

Variables of interest	Model 1: Screen^– vs. Screen⁺		Model 2: CTBIE^– vs. CTBIE⁺
Variables of interest	OR (95% CI)	P-value	OR (95% CI)	P-value
VR-12 physical functioning	0.96 (0.96–0.97)	< 0.001	0.99 (0.98–0.99)	< 0.001
High blood pressure/hypertension	0.78 (0.70–0.88)	< 0.001	0.97 (0.82–0.99)	0.732
Stroke	3.48 (2.06–5.90)	< 0.001	1.05 (0.60–1.83)	0.860
High cholesterol/hyperlipidemia	0.96 (0.86–1.07)	0.477	0.89 (0.76–1.06)	0.208
Other circulatory problems	1.21 (0.91–1.59)	0.188	0.82 (0.57–1.18)	0.299
Obesity (BMI > 30)	1.04 (0.94–1.15)	0.442	1.10 (0.96–1.28)	0.172
VA health care use (51–100%)	1.20 (1.07–1.35)	0.001	0.91 (0.76–1.08)	0.303
Overnight hospital visits (1 or more)	1.19 (1.03–1.37)	0.022	1.06 (0.88–1.28)	0.546
Rx medications (1 or more)	1.37 (1.19–1.56)	< 0.001	0.83 (0.66–1.03)	0.093
Non-Rx medications (1 or more)	1.44 (1.26–1.64)	< 0.001	0.91 (0.76–1.08)	0.271

All models are adjusted for age group (18–29; 30–39; 40–49; and ≥ 50), sex (male; female); race/ethnicity (White, Non-Hispanic; Black, Non-Hispanic; Hispanic; Asian; Multiracial; Another Race/Ethnicity); and PTSD diagnosis (yes; no). Logistic regression was used to estimate the odds of being classified into the Screen⁺ group for Model 1 (n = 13,008) and the CTBIE⁺ group for Model 2 (n = 4135) as a function of health outcomes. The Screen^– and CTBIE^– groups served as the reference group in Models 1 and 2, respectively.
