Background Atopic dermatitis (AD) has been associated with cardiovascular risk factors and diseases, but epidemiological studies to date have found conflicting results. Objectives To determine the associations of AD with hypertension, type 2 diabetes (T2D), myocardial infarction (MI) and stroke. Methods We conducted a cross-sectional analysis of baseline data from the Canadian Partnership for Tomorrow Project, which includes Canadian residents aged 30–74 years living in British Columbia, Alberta, Ontario, Quebec and the Atlantic Provinces. We excluded participants with incomplete data on AD, hypertension, T2D, MI or stroke, who had type 1 or gestational diabetes or who developed any of the outcomes at an age prior to a diagnosis of AD. This left 259 119 participants in our analysis. We used logistic regression to calculate age- and sex-, and multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) between AD and subsequent hypertension, T2D, MI and stroke. Results AD was reported by 21 379 (8·4%) participants. In total, 52 787 cases of hypertension, 12 739 cases of T2D, 4390 cases of MI and 2235 cases of stroke were reported by participants at enrolment. In the multivariable-adjusted model, AD was associated with decreased odds of hypertension (OR 0·87, 95% CI 0·83–0·90), T2D (OR 0·78, 95% CI 0·71–0·84), MI (OR 0·87, 95% CI 0·75–1·00) and stroke (OR 0·79, 95% CI 0·66–0·95). Conclusions We did not find evidence of a positive association between AD and subsequent hypertension, T2D, MI or stroke; AD was inversely associated with these outcomes in our study. Given our findings and the conflicting literature, AD is likely not a major risk factor for cardiovascular disease.
