ABSTRACT
【Objective】 To investigate the association of platelet/albumin ratio （PAR）， platelet/hemoglobin （PHR） and C-reactive protein/albumin （CAR） with diabetes mellitus. 【Methods】 Based on the data of China Health and Nutrition Survey （CHNS2009）， with gender and age matched by their ID， a total of 8 258 individuals with serological test results were finally included and were divided into diabetes group and control group according to the fasting blood glucose and HbA1c， and then the blood lipid and blood cell changes， PAR， PHR and CAR differences between groups were compared， and the correlation analysis of diabetes was performed. 【Results】 Compared with those in the control group， serum uric acid， total cholesterol， triacylglycerol and low-density lipoprotein cholesterol （LDL-C） were significantly increased in diabetes group， while high-density lipoprotein cholesterol （HDL-C） was significantly decreased. Besides， there was no significant difference in PAR or PHR between the two groups， while CAR was significantly increased in diabetes （0.48±0.18 vs. 0.08±0.23， P<0.001）， and was positively correlated with the levels of fasting glucose （r=0.181 8， P<0.001）， HbA1c （r=0.186 6， P<0.001）， and HOMA-IR （r=0.188 1， P=0.003）. However， CAR was not an independent risk factor for diabetes. In addition， increased red blood cell count （B=1.324， 95% CI： 1.182-1.483， P<0.001） and leukocytes count （B=1.230， 95% CI： 1.166-1.298， P<0.001） may be independent risk factors for the incidence of diabetes. 【Conclusion】 CAR is correlated with diabetes mellitus， but it is not an independent risk factor. Dyslipidemia， elevated leukocytes and red blood cell counts may be independent risk factors for diabetes， but further study is needed.
