Abstract

Objective

To provide a descriptive analysis of the nutritional status of a sample of women with anorexia nervosa (AN).

Materials and methods

Descriptive observational study of women attending an outpatient clinic for AN.

Results

Thirty-five patients were evaluated, with a mean age of 23.6 ± 10.7 years and a body mass index of 18.3 ± 3.53 kg/m². A total of 73.52% were malnourished (40% with severe malnutrition). Muscle strength was 24.3 ± 3.53 kg; 16 patients (55.88%) showed strength below the 20th percentile, but only 3 fell below the cutoff defining sarcopenia.

Muscle mass variables assessed included: appendicular skeletal muscle mass, 14.7 ± 2.47 kg/m²; fat-free mass index, 14.8 ± 1.47 kg/m²; appendicular skeletal muscle mass index, 5.52 ± 0.629 kg/m²; anteroposterior diameter of the rectus femoris muscle (Y-axis), 1.18 ± 0.32 cm; and cross-sectional area of the same muscle, 3.54 ± 1.29 cm². The ratio of the lateral diameter of the rectus femoris (X-axis) to the Y-axis, used as an index of muscle quality, was 3.09 ± 1.17.

Patients with severe malnutrition had lower adipose tissue content and reduced appendicular skeletal muscle mass compared with the rest of the cohort.

Phase angle was 5.85 ± 0.77°, and standardized phase angle was – 0.92 ± 0.89. Both showed a good positive correlation with body cell mass.

Conclusions

Malnutrition is extremely prevalent among patients with AN; however, sarcopenia—according to conventional criteria—is not. Morphofunctional differences were observed according to nutritional status.

神经性厌食症妇女的营养状况。估价morfofuncional

目的对女性神经性厌食症（AN）患者的营养状况进行描述性分析。材料与方法对在门诊就诊的an患者进行描述性观察研究。结果35例患者，平均年龄23.6±10.7岁，体重指数18.3±3.53 kg/m2。营养不良占73.52%，其中重度营养不良占40%。肌力24.3±3.53 kg；16例（55.88%）肌力低于第20百分位，但只有3例低于肌少症的临界值。评估的肌肉质量变量包括：阑尾骨骼肌质量，14.7±2.47 kg/m2；无脂质量指数：14.8±1.47 kg/m2；阑尾骨骼肌质量指数，5.52±0.629 kg/m2；股直肌前后径（y轴），1.18±0.32 cm；而同一肌肉的横截面积为3.54±1.29 cm2。股直肌外侧直径（x轴）与y轴的比值，作为肌肉质量的指标，为3.09±1.17。与其他患者相比，严重营养不良的患者脂肪组织含量较低，阑尾骨骼肌质量减少。相位角为5.85±0.77°，标准化相位角为- 0.92±0.89。两者均与机体细胞质量呈良好的正相关。结论AN患者营养不良极为普遍；然而，根据传统的标准，肌肉减少并不是。根据营养状况观察形态功能差异。

期刊介绍： Endocrinología, Diabetes y Nutrición is the official journal of the Spanish Society of Endocrinology and Nutrition (Sociedad Española de Endocrinología y Nutrición, SEEN) and the Spanish Society of Diabetes (Sociedad Española de Diabetes, SED), and was founded in 1954. The aim of the journal is to improve knowledge and be a useful tool in practice for clinical and laboratory specialists, trainee physicians, researchers, and nurses interested in endocrinology, diabetes, nutrition and related disciplines. It is an international journal published in Spanish (print and online) and English (online), covering different fields of endocrinology and metabolism, including diabetes, obesity, and nutrition disorders, as well as the most relevant research produced mainly in Spanish language territories. The quality of the contents is ensured by a prestigious national and international board, and by a selected panel of specialists involved in a rigorous peer review. The result is that only manuscripts containing high quality research and with utmost interest for clinicians and professionals related in the field are published. The Journal publishes Original clinical and research articles, Reviews, Special articles, Clinical Guidelines, Position Statements from both societies and Letters to the editor. Endocrinología, Diabetes y Nutrición can be found at Science Citation Index Expanded, Medline/PubMed and SCOPUS.
