Frailty linked most to death in a Chinese cohort aged 45 and up
The modeled death rate was about 0.16 per person-year with frailty alone versus 0.07 with neither frailty nor diabetes.

Chinese adults aged 45 and older living in the community—16,658 people—were tracked across five survey waves from 2011 to 2020 in a cohort analysis. Frailty means reduced resilience to illness and other stresses. Researchers modeled transitions among five states: diabetes alone, frailty alone, both conditions, neither condition and death.
Over nine years, 2,417 participants (14.5%) died. Frailty carried the dominant mortality burden, while diabetes added little beyond it. Having both conditions was not clearly linked to a higher death rate than expected from their separate associations. Rates per person-year account for the combined time participants were followed. The transitions between diabetes and frailty described associations conditional on participants’ starting condition, not evidence that either condition accelerated the other.
Why it matters
The authors recommend prioritizing early detection of frailty and reducing risk factors shared by frailty and diabetes in older adults’ care.
Caveats
Estimates of the transition from frailty to diabetes changed markedly when people with either condition at enrollment were excluded. The preprint has not been peer-reviewed, and its population did not cover younger adults or care-home residents.
