Presbyphagia:Dysphagia in the elderly

Dysphagia has been classified as a“geriatric syndrome”and can lead to serious complications that result in a tremendous burden on population health and healthcare resources worldwide.A characteristic age-related change in swa-llowing is defined as“presbyphagia.”Medical imaging has shown some changes that seriously affect the safety and efficacy of swallowing.However,there is a general lack of awareness of the effects of aging on swallowing function and a belief that these changes are part of normal aging.Our review provides an overview of presbyphagia,which has been a neglected health problem for a long time.Attention and awareness of dysphagia in the elderly population should be strengthened,and targeted intervention measures should be actively imple-mented.

青年人和老年人的自发吞咽音特征对比分析

目的对比分析青年人和老年人的自发吞咽音特征。方法健康受试者100例，分为青年组（19～30岁）和老年组（60～85岁），每组50例（男女各25例）。2组研究对象均测量颈围（绕甲状软骨水平的颈部周径）和体重指数（BMl）。在甲状软骨以下气管左侧检测自发吞咽音20rain，采用RavenPr01．5．0进行吞咽音切分、标注和吞咽声学指标测算，包括每分钟自发吞咽频率（SPM）、吞咽音长、能耗、半耗能时长及半耗能时长占比，使用R3．4．0进行统计分析。结果青年组的平均颈围（34．31±3．45）cm，与老年组[（33．95±3．00）cm]比较，差异无统计学意义（P=0．5789）；青年组的BMI为（21．97±2．65）kg／m。，低于老年组[（23．43±2．89）kg／m。]，组间差异有统计学意义（P=0．0219）。老年组的SPM为（0．39＋0．34）次／min，显著少于青年组[（0．91-＋0．51）次／min]，且组间差异有统计学意义（P〈O．01）；老年组的吞咽音长为（0．92±0．29）s，显著长于青年组[（0．84＋_0．26）s]，且组间差异有统计学意义（P〈0．01）；老年组单次吞咽消耗的能量为（76．88＋_9．82）dB，显著高于青年组[（75．43±8．93）dB]，差异有统计学意义（P〈0．05）；老年组单次吞咽消耗一半能量所需时间为（0．43~0．24）S，显著长于青年组[（0．38＋_0．19）s]，差异有统计学意义（P〈0．01），但该时间占吞咽音长的比例在青年组[（48．30＋_28．20）％]和老年组[（49．00_＋29．90）％]之间差异无统计学意义（P=O．6859）。结论与青年人相比，老年人的自发吞咽频率明显减少，吞咽音明显延长。
