To examine whether oral health in hospitalised elderly was associated with body cell mass (BCM) measured with Bioimpedance spectroscopy.
Body cell mass is the tissue producing the metabolic work necessary for all body functions. BCM is mainly muscle tissue. Low BCM is associated with diseases, ageing and poor nutritional status. Reduced oral health is also associated with these parameters; thus, BCM and oral health may be related.
Body cell mass was measured using Bioimpedance spectroscopy in 138 acutely hospitalised elderly ≥70 years. The number of own teeth, posterior occluding tooth pairs and decayed teeth were registered. Oral hygiene was registered with Mucosal-Plaque Score, an index based on assessment of plaque accumulation and mucosal/gingival inflammation. Mini Nutritional Assessment-Short Form, body mass index and handgrip strength were used as nutritional indicators. Comorbidity was assessed with Cumulative Index Rating Scale.
Mean age was 83.2 ± 5.9 years, ranging from 70 to 101 years. Dentition status was significantly and positively associated with BCM. Reduced oral hygiene was significantly associated with low BCM. These findings remained significant after adjusting for confounders.
These results show that compromised oral health was significantly associated with reduced BCM in hospitalised elderly.
研究通过生物电阻抗谱法测量的身体细胞量（BCM）与住院老年人的口腔健康之间的关系。
身体细胞量是产生所有身体功能所需代谢工作的组织。BCM 主要是肌肉组织。低 BCM 与疾病、衰老和营养不良状况有关。口腔健康状况下降也与这些参数有关；因此，BCM 和口腔健康可能相关。
对 138 名≥70 岁的急性住院老年人使用生物电阻抗谱法测量 BCM。记录自己的牙齿数、后牙对合牙数和龋齿数。口腔卫生情况采用基于菌斑积累和黏膜/牙龈炎症评估的黏膜-菌斑评分（Mucosal-Plaque Score）进行登记。微型营养评估-简短表格、身体质量指数和握力用作营养指标。累积指数评分量表用于评估合并症。
平均年龄为 83.2 ± 5.9 岁，年龄范围为 70 岁至 101 岁。牙齿状况与 BCM 呈显著正相关。口腔卫生状况较差与 BCM 降低显著相关。这些发现在调整混杂因素后仍然显著。
这些结果表明，住院老年人口腔健康状况受损与 BCM 降低显著相关。
