Gender-specific associations between coronary heart disease and other chronic diseases: cross-sectional evaluation of national survey data from adult residents of Germany.

Background Combinations of coronary heart disease (CHD) and other chronic conditions complicate clinical management and increase healthcare costs. The aim of this study was to evaluate gender-specific relationships between CHD and other comorbidities. Methods We analyzed data from the German Health Interview and Examination Survey (DEGS1), a national survey of 8152 adults aged 18.79 years. Female and male participants with self-reported CHD were compared for 23 chronic medical conditions. Regression models were applied to determine potential associations between CHD and these 23 conditions. Results The prevalence of CHD was 9% (547 participants): 34% (185) were female CHD participants and 66% (362) male. In women, CHD was associated with hypertension (OR = 3.28 (1.81.5.9)), lipid disorders (OR = 2.40 (1.50.3.83)), diabetes mellitus (OR = 2.08 (1.24.3.50)), kidney disease (OR = 2.66 (1.101.6.99)), thyroid disease (OR = 1.81 (1.18.2.79)), gout/high uric acid levels (OR = 2.08 (1.22.3.56)) and osteoporosis (OR = 1.69 (1.01.2.84)). In men, CHD patients were more likely to have hypertension (OR = 2.80 (1.94.4.04)), diabetes mellitus (OR = 1.87 (1.29.2.71)), lipid disorder (OR = 1.82 (1.34.2.47)), and chronic kidney disease (OR = 3.28 (1.81.5.9)). Conclusion Our analysis revealed two sets of chronic conditions associated with CHD. The first set occurred in both women and men, and comprised known risk factors: hypertension, lipid disorders, kidney disease, and diabetes mellitus. The second set appeared unique to women: thyroid disease, osteoporosis, and gout/high uric acid. Identification of shared and unique gender-related associations between CHD and other conditions provides potential to tailor screening, preventive, and therapeutic options.
