OBJECTIVES: To describe (1) the frequency and utility of clinically relevant
spinal cord injury (SCI)-specific and general population thresholds for obesity
and sarcopenic obesity;
and (2) the fat and lean soft tissue distributions based
on the neurologic level of injury and the American Spinal Injury Association
Impairment Scale. DESIGN: Cross-sectional. SETTING: Tertiary SCI rehabilitation
hospital. PARTICIPANTS: Persons (N=136; men, n=100; women, n=36) with chronic
(mean +/- SD: 15.6+/-11.3y postinjury) tetraplegia (n=66) or paraplegia (n=70).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Body composition was
assessed with anthropometrics and whole-body dual-energy x-ray absorptiometry.
Muscle atrophy was quantified using a sarcopenia threshold of appendicular lean
mass index (ALMI) (men, </=7.26kg/m2; women, </=5.5kg/m2). Obesity was defined by
percentage body fat (men, >/=25%; women, >/=35%), visceral adipose tissue
(>/=130cm2), and SCI-specific obesity thresholds (body mass index [BMI]
>/=22kg/m2; waist circumference >/=94cm). Sarcopenic obesity was defined as the
presence of both sarcopenia and obesity. Groups were compared based on impairment
characteristics using an analysis of covariance. RESULTS: Sarcopenic obesity was
prevalent in 41.9% of the sample. ALMI was lower among participants with
motor-complete (6.2+/-1.3kg/m2) versus motor-incomplete (7.5+/-1.6kg/m2) injuries
(P<.01). Whole-body fat was greater among participants with tetraplegia
(28.8+/-11.2kg) versus paraplegia (24.1+/-8.7kg; P<.05). Compared with general
population guidelines (20.6%), SCI-specific BMI thresholds identified all the
participants with obesity (77.9%) based on percentage body fat (72.1%).
CONCLUSIONS: The observed frequency of sarcopenic obesity in this sample of
individuals with chronic SCI is very high, and identification of obesity is
dissimilar when using SCI-specific versus general population criteria.
