研究问题
This study is to investigate the association between oral frailty and grip strength in older adults, focusing on the moderating role of body mass index (BMI).
方法
A multicentre cross-sectional study was conducted in Beijing, China, between July, 2024 and March, 2026.；Participants aged 60 years or older were recruited using convenience sampling from eight communities.；Oral frailty was prevalent in 55.5% of participants.
核心结论
Oral frailty is a multidimensional state associated with physical decline.；After adjusting for confounders, oral frailty (β = -0.42, p < 0.001) and decreased oral motor skills (β = -0.10, p = 0.001) were independently associated with reduced grip strength.；Low BMI significantly amplified the negative impact of oral frailty on grip strength.；Oral frailty and decreased oral motor skills are core independent factors for reduced grip strength in older adults.
局限
A multicentre cross-sectional study was conducted in Beijing, China, between July, 2024 and March, 2026.
对本项目的价值
观察性关联，仅用于假说生成，不可作因果：功能结局（衰弱 / 肌少症）是临床转化最可及的终点，适合作为一期终点候选。 ｜ 价值分 1.0/5（★☆☆☆☆）

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。
