Background: Women with diabetes are at higher risk of CVDs than men. We investigated the associations between the degree of risk factor control and CVD in women and men with diabetes.
Methods: A total of 16,760 diabetes patients from UK Biobank were included. The exposure was the number of optimized risk factors including HbA1c level <53 mol/mol (7%) , blood pressure <140/90 mm/Hg, and non-HDL-cholesterol <130 mg/dl.
Results: During a mean follow-up of 8.4 years, 2000 incident CVD were documented, including 1685 IHD and 412 stroke. Number of risk-factor control was inversely associated with the risks of IHD, stroke and total CVD, and such associations were stronger in women than men (P for interaction with sex=0.012, 0.018 and 0.017, respectively) . The two most important risk factors for men were blood pressure and non-HDL-cholesterol, while for women were HbA1c and non-HDL-cholesterol. In addition, as compared with non-diabetic controls, the diabetes-related risk of CVD was theoretically eliminated when 2 or more risk-factors were under control in women, and 3 risk-factors were under control in men.
Conclusion: Among diabetes patients, to control the risk factors within the target range benefit more in women than men in preventing subsequent risk of CVD. Our findings highlight the importance of raising awareness of control of risk factors and provide evidence for the sex-specific priority of control strategies.
