EXPRESS: Cerebrovascular disease at young age is related to motherâs health during the pregnancy â the Northern Finland Birth Cohort 1966 study.
Abstract
BACKGROUND AND PURPOSE\nFor prevention of cerebrovascular diseases at younger age, it is important to understand the risk factors occurring early in life. We investigated the relationship between mothersâ general health during pregnancy and the offspringâs risk of cerebrovascular disease in age of 15 to 52 years.\n\n\nMETHODS\nWithin the population-based prospective Northern Finland Birth Cohort 1966, 11,926 persons were followed from antenatal period to 52 years of age. Information on their motherâs ill health conditions, i.e., hospitalizations, chronic diseases, medications, vitamin or iron supplement, fever, anemia, mood, and smoking was collected from 24th gestational week onwards. Ischemic and hemorrhagic cerebrovascular diseases of the offspring were identified from national registers in Finland. Cox proportional hazard models were used to estimate the association of motherâs health conditions with incidence of cerebrovascular disease in the offspring, with adjustments for potential confounders.\n\n\nRESULTS\nDuring 565,585 person-years of follow-up, 449 (2.8%) of the offspring had a cerebrovascular disease. Hospitalization during pregnancy was associated with an increased risk of cerebrovascular disease in the offspring (hazard ratio (HR)=1.49; 95% confidence interval (CI) 1.06-2.08) after adjustment for confounders, as was having more than three ill health conditions (HR=1.89; CI 1.14-3.11). Not using vitamin or iron supplement associated with increased risk for cerebrovascular disease in the offspring (HR=1.39; CI 1.01-1.89).\n\n\nCONCLUSIONS\nThe results suggest that the risk of cerebrovascular disease may start as early as during the antenatal period, and the health characteristics of mothers during pregnancy may play a role in cerebrovascular disease risk of the offspring.
