Energy intakes of adults with spinal cord injury (SCI) have been reported to be relatively low, with many micronutrients below recommended amounts, but little is known about the diets of athletes with SCI. The purpose of this cross-sectional, observational study was to assess energy intakes and estimate the prevalence of dietary inadequacy in a sample of elite Canadian athletes with SCI (n = 32). Three-day self-reported food diaries completed at home and training camp were analyzed for energy (kcal), macronutrients, vitamins, and minerals and compared with the dietary reference intakes (DRIs). The prevalence of nutrient inadequacy was estimated by the proportion of athletes with mean intakes below the estimated average requirement (EAR). Energy intakes were 2,156 ± 431 kcal for men and 1,991 ± 510 kcal for women. Macronutrient intakes were within the acceptable macronutrient distribution ranges. While at training camp, >25% of men had intakes below the EAR for calcium, magnesium, zinc, riboflavin, folate, vitamin B12, and vitamin D. Thiamin, riboflavin, calcium, and vitamin D intakes were higher at home than training camp. Over 25% of women had intakes below the EAR for calcium, magnesium, folate, and vitamin D, with no significant differences in mean intakes between home and training camp. Vitamin/mineral supplement use significantly increased men's intakes of most nutrients but did not affect prevalence of inadequacy. Women's intakes did not change significantly with vitamin/mineral supplementation. These results demonstrate that athletes with SCI are at risk for several nutrient inadequacies relative to the DRIs.
脊髓损伤(SCI)成年人的能量摄入量相对较低,许多微量营养素摄入量低于推荐量,但对 SCI 运动员的饮食知之甚少。本横断面观察性研究的目的是评估精英加拿大 SCI 运动员(n=32)的能量摄入量,并估计饮食不足的患病率。在家中和训练营完成的为期 3 天的自我报告食物日记用于分析能量(千卡)、宏量营养素、维生素和矿物质,并与膳食参考摄入量(DRIs)进行比较。通过平均摄入量低于估计平均需求量(EAR)的运动员比例估计营养素不足的患病率。男性的能量摄入量为 2156±431 千卡,女性为 1991±510 千卡。宏量营养素摄入量在可接受的宏量营养素分布范围内。在训练营期间,超过 25%的男性的钙、镁、锌、核黄素、叶酸、维生素 B12 和维生素 D 的摄入量低于 EAR。在家时,男性的硫胺素、核黄素、钙和维生素 D 的摄入量高于训练营。超过 25%的女性的钙、镁、叶酸和维生素 D 的摄入量低于 EAR,且在家和训练营时的平均摄入量无显著差异。维生素/矿物质补充剂的使用显著增加了男性对大多数营养素的摄入量,但并未影响不足的患病率。女性的摄入量随维生素/矿物质补充剂的使用无明显变化。这些结果表明,与 DRIs 相比,SCI 运动员存在多种营养素不足的风险。
