Background: Gestational hypertensive disorders and diabetes are well-known to increase the risk of cardiovascular disease (CVD) and diabetes later in life. However, there were few researches to evaluate the association between family history of cardiovascular disease and the occurrence of pregnancy-related medical disorders. We aimed to investigate whether family history of CVD could predict gestational hypertensive disorders and diabetes. Methods: The Korean Nurses’ Survey was conducted through web-based computer-assisted self-administered questionnaires, which were compiled by consultation to cardiologists, gynecologists, and statisticians, from October to December 2011. We enrolled a total of 9,989 female registered nurses who could answer reliably the questionnaires based on their medical knowledge. Multivariate logistic regression analysis was used to clarify the effect of family history of CVD on pregnancy-related medical disorders. Result: In this survey, 3900 subjects had more than 1 pregnancy. Among them, 247 interviewees (6.3%) had experienced hypertensive disorders during pregnancy, which included preeclampsia (n = 160, 4.1%) and transient hypertension (n = 144, 3.7%), and 120 (3.1%) had experienced gestational diabetes. And, 2872 subjects (73.6%) answered that they had at least 1 family history of CVD. Having family history of CVD increased the risk of gestational hypertensive disorders (adjusted RR 1.51, 95% CI 1.08-2.11, p = 0.015) and diabetes (adjusted RR 2.40, 95% CI 1.38-4.17, p = 0.002). In particular, family history of hypertension was significantly associated with gestational hypertensive disorders (adjusted RR 2.00, 95% CI 1.47-2.50, p <0.001), and diabetes was highly related with gestational diabetes (adjusted RR 3.37, 95% CI 2.35-4.83, p <0.001), respectively. Furthermore, this relationship was observed regardless of maternal parity. Conclusion: Family history of CVD was a significant predictor of pregnancy-related medical disorders in this survey. Meticulous history taking for family history of CVD can provide the risk of gestational hypertensive disease and diabetes. Thus, special attention should be paid to women with family history of CVD during pregnancy.
