Abstract

BACKGROUND/AIMS:

Women with diabetes experience a disproportionately greater burden of diabetic kidney disease (DKD) risk factors compared to men; however, sex-specific differences in DKD are not well defined. The effect of age on sex differences in DKD is unknown.

METHODS:

We performed a cross-sectional analysis of the prevalence of DKD (eGFR <60 ml/min/1.73 m(2) or microalbuminuria), advanced DKD (eGFR <30 ml/min/1.73 m(2)), and common DKD risk factors in the Pathways Study (n = 4,839), a prospective cohort study of diabetic patients from a managed care setting. Subjects were stratified by age <60 and ≥60 years to examine for differences by age. Logistic regression models examined the association between sex and prevalence of DKD and risk factors.

RESULTS:

Women of all ages had 28% decreased odds of DKD (OR 0.72, 95% CI 0.62-0.83); however, they had a greater prevalence of advanced DKD (OR 1.67, 95% CI 1.05-2.64), dyslipidemia (OR 1.42, 95% CI 1.16-1.74), and obesity (OR 1.87, 95% CI 1.60-2.20) compared to men. Women had similar odds of hypertension and poor glycemic control as men. Women ≥60 years had increased odds of advanced DKD, hypertension, dyslipidemia, and obesity compared to similarly aged men. Women <60 years had increased odds of obesity compared to their male counterparts.

CONCLUSION:

Women with diabetes had an increased prevalence of advanced DKD and common DKD risk factors compared to men and these disparities were most prominent amongst the elderly.
