RESUMEN
BACKGROUND: It remains unclear whether cardiovascular risk factors and access to healthcare for veterans with cardiovascular disease (CVD) vary among US regions. This study sought to determine the extent of regional variations in cardiovascular risk factors and access to medical care in a cohort of veterans with CVD in the USA. METHODS: The 2016 Centers for Disease Control Behavioral Risk Factor Surveillance Survey was utilized to identify a cohort of veteran patients with CVD. Participants were classified based on four US regions: (1) Northeast, (2) Midwest, (3) South, and (4) West. We compared demographic data, medical history, and access to care for veterans of each US region. The outcomes of interest included financial barriers to medical care and annual medical checkup. RESULTS: Among the 13 835 veterans, 18.3% were from the Northeast, while 23.5, 37.1, and 21.1% were from the Midwest, South, and West, respectively. Veterans of each region differed significantly with respect to demographic characteristics, prior medical history, and access to care. Rates of financial barriers to medical care were similar across the four regions (7.3 vs. 7.1 vs. 8.0 vs. 6.9%, P = 0.203). Veterans from the West had the lowest rates of medical checkup within the past year (91.7 vs. 89.5 vs. 91.4 vs. 86.6%). On multivariate analysis, the Midwest [odds ratio (OR) 0.69; 95% CI, 0.53-0.89] and West (OR 0.53; 95% CI 0.41-0.68) regions were independently associated with lower rates of medical checkup within the past year compared to the Northeast. CONCLUSIONS: In this observational study involving US veterans with CVD, cardiovascular risk factors and frequency of annual medical checkup differed amongst each US region. Further large-scale studies examining the prevalence of impaired access to care and quality of care in US veterans with CVD are warranted.

Timing light systems are commonly used to measure sprint times of athletes. In this study, the reliability and effect of timing light height on sprint times was investigated. Two sets of timing lights set at hip and shoulder height, simultaneously timed subjects over 10 and 20 meters. The within-trial variation of both timing light heights were equally consistent; all coefficients of variation (CV) less than 1.2% with less variability associated with the longer (20 m) distances (CV < 0.85%). The typical error between the two timing light heights for both distances was small (< or = 1.3%). The mean difference between the two heights was significantly different (0.7 second, 95% CL = 0.05-0.10 second) at both the 10 and 20 m distances. Faster times were recorded at hip height as opposed to shoulder due to the legs breaking the beam before the upper body. It is suggested that standardized procedures are necessary for speed assessment using timing lights in order for comparisons to be made between athletic populations.
