Association of hemoglobin levels with cause-specific and all-cause mortality among older adults: a prospective cohort study.

ABSTRACT:

Background

Hemoglobin (Hb) optimal levels is clinically and biologically heterogeneous, data of older adults was not available.

Methods

We used data of participants enrolled in Shenzhen Healthy Ageing Research, in which the baseline Hb was measured in 223,407 older adults aged 65 or older to evaluation of Hb optimal levels. The vital status of the participants by 31 December, 2021 was determined. We estimated the hazard ratios with 95% confidence intervals for all-cause or cause-specific mortality using multivariable Cox proportional hazards models, and Cox models with restricted cubic spline (RCS) was used for all-cause mortality.

Results

Overall, 6,722 deaths occurred during a mean follow-up of 3.01 years from 2018 to 2021. The risk for all-cause and cause-specific
