Does incident type 2 diabetes mellitus confer a higher relative cardiovascular risk in women compared to men, and are there sex disparities in risk factor management?
While women with incident T2DM experience similar relative increases in cardiovascular risk as men, they face significant disparities in the prescription of guideline-directed medical therapies like lipid-lowering medications and ACE inhibitors.
BACKGROUND: With recent changes in the United Kingdom's clinical practice for diabetes mellitus care, contemporary estimates of sex disparities in cardiovascular risk and risk factor management are needed. METHODS: In this retrospective cohort study, using the Clinical Practice Research Datalink linked to hospital and death records for people in England, we identified 79 985 patients with incident type 2 diabetes mellitus (T2DM) between 2006 to 2013 matched to 386 547 patients without diabetes mellitus. Sex-stratified Cox models were used to assess cardiovascular risk. RESULTS: Compared with women without T2DM, women with T2DM had a higher cardiovascular event risk (adjusted hazard ratio, 1.20 95% confidence interval, 1.12-1.28) with similar corresponding data in men (hazard ratio, 1.12 1.06-1.19), leading to a nonsignificant higher relative risk in women (risk ratio, 1.07 0.98-1.17). However, some important sex differences in the management of risk factors were observed. Compared with men with T2DM, women with T2DM were more likely to be obese, hypertensive, and have hypercholesterolemia, but were less likely to be prescribed lipid-lowering medication and angiotensin-converting enzyme inhibitors, especially if they had cardiovascular disease. CONCLUSIONS: Compared with men developing T2DM, women with T2DM do not have a significantly higher relative increase in cardiovascular risk, but ongoing sex disparities in prescribing should prompt heightened efforts to improve the standard and equity of diabetes mellitus care in women and men.
