BACKGROUND

Cardiometabolic syndrome in individuals who are aging with spinal cord injury (SCI) increases the risk of cardiovascular disease and diabetes. Longitudinal research is needed on the natural progression of cardiometabolic syndrome in SCI.

OBJECTIVE

To identify the magnitude of changes in biomarkers of cardiometabolic syndrome and diabetes over time in people aging with SCI, and to discern how these biomarkers relate to demographics of race/ethnicity and sex.

METHODS

This cohort study was a follow-up of a convenience sample of 150 participants (mean age, 51.3; duration of SCI, 27.3 years) from a full cohort of 845 who participated in research in which physiologic and serologic data on cardiovascular disease had been prospectively collected (1993-1997). Inclusion criteria were adults with traumatic-onset SCI. Average years to follow-up were 15.7 ± 0.9. Assessments were age, race, level and completeness of injury, duration of injury, blood pressure, body mass index, waist circumference, serum lipids, fasting glucose, hemoglobin A1c, and medications used. Primary outcome was meeting at least 3 of the criteria for cardiometabolic syndrome.

RESULTS

The frequency of cardiometabolic syndrome increased significantly from 6.7% to 20.8% or 38.2% according to 2 definitions. It was significantly higher in Hispanics and apparently higher in women. Diabetes increased significantly by a factor of 6.7.

CONCLUSION

Our data indicate clinically important increases in the frequency of cardiometabolic syndrome, especially among Hispanic and female participants, and a similar increase in diabetes among individuals aging with SCI. Clinical practice guidelines need to be customized for women and Hispanics with SCI.
