Abstract:
Objective:To explore the gender-specific risk factors of new-onset cerebral hemorrhage.
Methods:In this prospective cohort study,a total of 98 961 participants((51.1±12.6)years old), who underwent the 2006 to 2007 physical examination and met the inclusion criteria, were enrolled from the Kailuanstudy cohort. There were 78 908 (79.7%) male,and 20 053 (20.3%) female.The incidence of cerebral hemorrhage was observed once per year until December 31, 2016.The difference on the incidence of cerebral hemorrhage between male and female was compared. Multivariate Cox regression analysis was applied to analyze therisk factors of cerebral hemorrhage events among different genders.
Results:The participants were followed up for(10.00±0.73) years,and 860 cerebral hemorrhage events were recorded during follow up. The incidence of cerebral hemorrhage in the population was 86.90/10 million person years (standardized incidence rate of 47.85/10 million person years). The incidence of cerebral hemorrhage was significantly higher in male (49.61/10 million person years) than in female (34.07/10 million person years, P<0.05). Multivariate Cox regression analysis showed that 45-59 years old, ≥ 60 years old, diabetes,and waist-hip ratio were more strongly related to new-onset of cerebral hemorrhage events in female than in male, and the hazard ratios(95%CI) were 2.33 (1.23-4.43) ,2.71 (1.30-5.66) ,2.16 (1.24-3.74) and 8.79 (1.42-54.32) in female versus 1.55 (1.21-1.97) ,2.16 (1.68-2.78) ,1.19 (0.93-1.53) and 3.21 (1.09-9.41) in male, respectively. The risk of male cerebral hemorrhage increased by 29% (HR=1.29, 95%CI 1.19-1.40) in male and 24% (HR=1.24, 95%CI 1.20-1.28) in female,when the systolic blood pressure increased 10 mmHg (1 mmHg=0.133 kPa).
Conclusions:The incidence of cerebral hemorrhage is higher in male than in female in this cohort.The association between systolic blood pressure and cerebral hemorrhage is stronger in male than that in female.The associations between age, waist-hip ratio, diabetes and cerebral hemorrhage are stronger in female than in male.
