Gu Y, Wu W, Bai J, et al. - Researchers examined how the number of teeth is associated with frailty among older Chinese adults using a nationally representative sample. In communities from nearly half of the counties and cities in 22 out of 31 provinces throughout China, they conducted a cross-sectional analysis using the 2014 wave data from the Chinese Longitudinal Healthy Longevity Survey, which used a targeted random-sampling design. The final analysis comprised 3,635 older adults (aged ≥ 65 years) who had completed the 2014 wave survey on the variables included in the study. They reported a frailty prevalence of 27.68% among these participants. The mean number of teeth present was 9.23 (SD = 10.03). Following adjustments for the covariates, significantly higher odds of frailty were evident among older adults with fewer teeth than those with 20 or more teeth (no teeth: OR = 2.07, 95% CI 1.53 to 2.80; 1 to 10 teeth: OR = 1.77, 95% CI 1.31 to 2.38), except for older adults with 11 to 20 teeth (OR = 1.30, 95% CI 0.93 to 1.82).
