What did studies of diabetes mellitus find?

4

Studies of diabetes mellitus measured 4 outcomes, among them Alzheimer's disease, PhenoAgeAccel and chronic conditions or disabilities.

Alzheimer's disease

no changein humans1HR 1.07

1 study
  1. Diabetes mellitus showed no clear effect on Alzheimer's disease in humans after adjusting for APOE ε4 mutations (HR 1.07, 95% CI 0.97–1.19, P = 0.177).

    “After adjusting for APOE ε4 mutations, there was no statistically significant difference in the risk association between DM and AD (HR = 1.07, 95% CI (0.97-1.19), P = 0.177)”

PhenoAgeAccel

1 study
  1. Diabetes mellitus is linked with higher PhenoAgeAccel in adults with high CRP (>3 mg/L), compared with adults without DM (+8.74 years (95% CI 8.25-9.22)).

    “PhenoAgeAccel increased by 1.66 years (95 % CI: 1.38-1.93), and 8.74 years (95 % CI: 8.25-9.22) in adults with prediabetes and DM, respectively”

Chronic conditions or disabilities

1 study
  1. Diabetes mellitus is linked with higher chronic conditions or disabilities in humans (native-born Americans born in the South).

    “PWD born in the South were more likely to have developed chronic conditions or disabilities and spent greater proportions of life with these two issues compared to other regions.”

Life expectancy

1 study
  1. Diabetes mellitus is linked with shorter life expectancy in humans (native-born Americans, by birth and current residence region) (5.8-10.8 years less).

    “At age 50, persons with diabetes (PWD) were expected to live on average 5.8-10.8 years less than their healthy equivalents across regions.”

What is diabetes mellitus linked with?

5

Studies link diabetes mellitus with 5 measures, among them frailty, cardiovascular mortality and mortality.

Frailty

1 study
  1. Diabetes mellitus is linked with a higher risk of frailty in humans (compared with normal glucose tolerance; Cox model adjusted for age and sex) (HR 1.44, 95% CI 1.07-1.94).

Cardiovascular mortality

1 study
  1. Diabetes mellitus is linked with a higher risk of cardiovascular mortality in humans (HR 3.57 (2.81-4.54)).

    “the multivariable-adjusted HRs (95%CIs) of all-cause and cardiovascular mortality in those with DM, CRP, and ageing acceleration were 3.22 (2.79-3.72), and 3.57 (2.81-4.54), respectively”
