研究问题
Objective assessment of swallowing function in community-dwelling older adults remains challenging.
方法
Four hundred and sixty-two participants (mean age 76.1 ± 3.4 years) were included.
核心结论
This study aimed to examine age- and sex-related differences in NWES-derived swallowing-related time metrics and their relationship with masticatory function.；Older adults from the Itabashi Longitudinal Study on Aging in 2024 were included.；Swallowing-related time was measured using NWES as pharyngeal clearance time (PCT), representing the duration of pharyngeal swallowing during water swallowing, and oral processing and swallowing time (OPST), reflecting the duration from oral processing to swallowing completion during cracker ingestion.；Masticatory function was assessed using a gummy jelly test. ‖ 结论：NWES-derived PCT and OPST showed different associations with age and masticatory function, with OPST associated with age in both sexes and with masticatory function in men.

本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
