OBJECTIVES: To assess different frequencies of dietary recalls while evaluating
caloric intake and the percentage of macronutrients in men with spinal cord
injury (SCI) and to examine the relations between caloric intake or percentage of
macronutrients and assessment of whole and regional body composition using
dual-energy x-ray absorptiometry. DESIGN: Cross-sectional and longitudinal.
SETTING: Laboratory and hospital. PARTICIPANTS:
Men with chronic (>1 y
postinjury) motor complete SCI (N=16). INTERVENTIONS: Participants were asked to
turn in a 5-day dietary recall on a weekly basis for 4 weeks. The averages of 5-,
3-, and 1-day dietary recalls for caloric intake and percentage of macronutrients
(carbohydrates, fat, protein) were calculated. Body composition was evaluated
using whole-body dual-energy
x-ray absorptiometry.
After overnight fast, basal
metabolic rate (BMR) was evaluated using indirect calorimetry and total energy
expenditure (TEE) was estimated. MAIN OUTCOME MEASURES: Caloric intake,
percentage of macronutrients, BMR, and body composition. RESULTS: Caloric intake
and percentage of macronutrients were not different after using 5-, 3-, and 1-day
dietary recalls (P>.05). Caloric intake was significantly lower than TEE (P<.05).
The percentage of fat accounted for 29% to 34% of the whole and regional body fat
mass (P=.037 and P=.022). The percentage of carbohydrates was positively related
to the percentage of whole-body lean mass (r=.54; P=.037) and negatively related
to the percentage of fat mass. CONCLUSIONS: The frequency of dietary recalls does
not vary while evaluating caloric intake and macronutrients.
Total caloric intake
was significantly lower than the measured BMR and TEE. Percentages of dietary fat
and carbohydrates are related to changes in body composition after SCI.
