Populations

Studied:: Cohort study of 5,171 middle-aged and older Chinese adults
What changed:: Multiple chronic diseases were more likely with highest versus lowest cumulative combined frailty and insulin-resistance scores (hazard ratio 6.52)
The catch:: Participant-reported disease diagnoses could misclassify who developed multiple chronic diseases
In the record:: One of 7 papers on cumulative estimated glucose disposal rate on record: 6 with results in people.
Why it’s aging research:: It measures an outcome that worsens with age.

Paper

The 5,171 middle-aged and older Chinese women and men in a prospective observational cohort study initially had no more than one of three conditions: diabetes or high blood sugar, heart disease, and stroke. During follow-up, 441 developed at least two.

Researchers scored frailty using 28 health deficits. They estimated insulin sensitivity—how well the body responds to insulin—from waist size, high blood pressure status and a blood sugar marker. They calculated a ratio of frailty to estimated insulin sensitivity and used measurements from 2011 and 2015 to assess cumulative exposure. Lower estimated insulin sensitivity, greater frailty and a higher ratio were each linked to developing multiple conditions after adjustment for other measured factors. Cumulative measures and patterns across the two assessments provided additional information beyond a single initial measurement.

Why it matters

The buildup of diabetes, heart disease and stroke is linked to functional difficulties and long-term care needs. Tracking frailty and metabolic health together may help characterize adults at increased risk.

Caveats

Disease outcomes relied on participants’ reports, and existing illness or other health differences could partly account for the links. The findings concern middle-aged and older Chinese adults without these multiple conditions at enrollment; the exploratory risk measures need validation before clinical use.

From the paper

Participants

This prospective cohort study included 5171 participants from the China Health and Retirement Longitudinal Study who were free of CMM at baseline.

Methods

Result

… and FI/eGDR were associated with HRs of 0.57 (95% CI, 0.51–0.64), 1.29 (95% CI, 1.19–1.40), and 1.39 (95% CI, 1.29–1.48), respectively; corresponding HRs for cumulative measures were 0.52 (95% CI, 0.46–0.59), 1.51 (95% CI, 1.40–1.64), and 1.52 (95% CI, 1.43–1.60).

Results

Limitation

First, observational associations cannot establish causality, and residual or unmeasured confounding remains possible.
