Objective
This study aims to investigate physical activities or triggering conditions at the time of spontaneous intracerebral hemorrhage(SICH) onset and to assess the influence of these factors according to the age.
Methods
From January 2000 to December 2009, we retrospectively reviewed clinical records and radiological data in SICH patients. Clinical and radiological data included sex, age, history of hypertension, diabetes mellitus, and cerebro- vascular accidents(CVA), season, time, place, and physical activities or triggering events at the time of ICH onset, and location of ICH. We analyzed these data according to the age(≥65-year-old vs. <65-year-old). Statistical analyses were performed by using chi-square and Student t-test. p-values of <0.05 were considered significant.
Results
The study group was composed of 238 men(59.2%) and 164 women(40.8%), with a mean age of 61.2±13.0 years old. Female and previous history of CVA were more frequently observed in older patients, but basal ganglia or pontine ICH in younger patients. There were no significant differences in physical activities or triggering events(p=0.409) and triggering conditions(p=0.300) between two groups. The triggering condition significantly affected outdoor activity (p=0.000). Defecation or micturition(14.4%), eating(12.2%), and sleeping(10.7%) were most common triggering condi- tions in both groups.
Conclusion
The occurrence of SICH is closely related to specific physical activity or triggering events and influenced by triggering conditions during outdoor activity. |
