Aims:
Anemia is common in diabetes patients, but its prevalence in pre-diabetes remains under-researched. Therefore, we aimed to investigate the incidence of anemia and potential risk factors in individuals with impaired fasting glucose using health examination data.
Methods:
A cohort of 7075 participants, all aged over 18 years and free of anemia at baseline, were included in this study to monitor the incidence of anemia through annual routine health check-ups. Cox regression models were used to estimate the age- and sex-adjusted hazard ratios of each risk factor.
Results:
The incidence of anemia among patients with impaired fasting glucose was 7.04 (95%CI: 6.08-8.00) per 1000 person-years overall, with a gender-specific incidence of 4.24 (95%CI: 3.37-5.10) and 15.21 (95%CI: 12.45-18.02) per 1000 person-years in men and women. COX regression analysis identified that female, lower levels of TC, LDL-C, ALT, AST, ALB, and alcohol drinking were associated with higher risk of anemia in individuals with impaired fasting glucose.
Conclusions:
In individuals with impaired fasting glucose, anemia incidence differed by gender and age, being higher in women than men and surpassing that of the general Chinese population. Furthermore, lower levels of TC, LDL-C, ALT, AST, ALB, and alcohol drinking were associated with higher risk of anemia in individuals with impaired fasting glucose.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
