So then, “why is there the view that women with type 2 diabetes need more aggressive cardiovascular risk reduction than men with diabetes?
“It probably comes back to confusion based on absolute risk versus a comparison of relative risk within each sex,” he asserted.
ADA Standards of Medical Care 2019 don’t mention gender
Lastly, in a meta-analysis published just in July this year involving more than 5 million participants, compared with men with diabetes, women with diabetes had a 58% and 13% greater risk of CHD and all-cause mortality, respectively.
“This points to an urgent need to develop sex- and gender-specific risk assessment strategies and therapeutic interventions that target diabetes management in the context of CHD prevention,” the authors concluded.
But, Dr. Davis noted, “It is not absolute vascular risk. It’s a relative risk compared across the two genders. In the paper, there is no mention of absolute vascular risk.
“Greater CVD mortality in women with and without diabetes, versus men, doesn’t mean there’s also an absolute vascular increase in women versus men with diabetes,” he said.
Moreover, Dr. Davis pointed out that in an editorial accompanying the 2015 meta-analysis in type 1 diabetes, Simmons had actually stated that absolute mortality rates are highest in men.
“I don’t know what happened to his epidemiology knowledge in the last 4 years but it seems to have gone backwards,” he joked to his debate opponent.
And, Dr. Davis asserted, even if there were a higher risk in women with type 1 diabetes, there is no evidence that cardiovascular risk reduction measures affect endpoints in that patient population. Only about 8% of people with diabetes in statin trials had type 1 diabetes.
Indeed, he noted, in the American Diabetes Association Standards of Medical Care in Diabetes – 2019, the treatment goals for individual cardiovascular risk factors do not mention gender.
What’s more, Dr. David said, there is evidence that women are significantly less likely than men to take prescribed statins and are more likely to have an eating disorder and underdose insulin, “suggesting significant issues with compliance. ... So, trying to get more intensive risk reduction in women may be a challenge.”
“Women with diabetes do not need more aggressive cardiovascular risk reduction than men with diabetes, irrespective of type,” he concluded.
