Abstract: Objective To investigate the correlation between dietary red meat intake and coronary heart disease （CHD） in patients with type 2 diabetes mellitus （T2DM）.Methods Patients of T2DM complicated with CHD in Nanshan District, Shenzhen were randomly selected as the case group and patients of T2DM without CHD as the control group. Two groups were matched by age （ ± 2 years） at a 1∶1 ratio. Self-made questionnaire and simplified food frequency questionnaire were used to investigate all the subjects. Conditional logistic regression was used to analyze the relationship between dietary red meat consumption and T2DM complicated with CHD.Results A total of 120 patients in the case group and 120 in the control group were investigated. The median of red meat intakes was 50.00（21.43,100.00） g per day in the case group and 42.86（21.43,50.00） g per day in the control group （P<0.05）.Conditional logistic regression showed that the OR of T2DM combined with CHD increased with the increase of dietary red meat intake（P_trend<0.05）.After adjusting for confounding variables, the risks of CHD in T2DM patients with red meat intake of 25-50 g per day and >50 g per day were 2.01 times （95%CI： 0.77-5.22） and 6.76 times （95%CI： 1.55-29.50） that of the patients with red meat intake < 25 g per day, respectively.Conclusion Dietary red meat intake of greater than 50 g per day may be a risk factor for CHD in T2DM patients.
