Background: Non-traumatic intracranial hemorrhage is the major public health problem which has global burden. It has high patient mortalities and morbidity with high number of young adult male patients in developing countries and the prevalence is increasing as the epidemiology of disease is changed. The accurate prevalence is not well known in the sub-Saharan countries due to lack of awareness about the problem and the absence of imaging modality. Identification of the major associated factor and preventive measure was tried but no adequate measure is taken with current evidence of high number of patient mortality and morbidity in developing countries. There is no enough study in Ethiopia and our setup. Knowing the prevalence and associated factors of this major public health problem will help to take early preventive measures and to work on the community. Objective: - Our primary aim was to determine the prevalence and associating factor of non traumatic intracranial hemorrhage in TGSH &FHRH who have brain imaging result. Methods: Facility based cross sectional study using simple random sampling was conducted with sample size of 442 in selected hospitals of Bahir Dar city from March 2021 to January 2022 by reviewing the charts of patients who had brain CT or MRI with no traumatic brain injury. Descriptive statistics and Binary logistic regression models were used to evaluate associations between non traumatic intracranial hemorrhage and associated factors.P-values less than 0.05 were considered statistically significant. Result: A total of 442 patients were included. The mean age was 62.47 years, and 55.2% were male. The prevalence of non traumatic intracranial hemorrhage was 46.4% with more male patients (57%).Most the patient presented with body weakness with over lap of symptoms. The most common site of intracranial hemorrhage was Basal ganglia and thalamus (P<0.001,OR=3.65,95%CI,2.76-5.34). Hypertension was the most common associated factor identified (86%) which has strong correlation with intracranial hemorrhage (p < .001,OR=5.06,95%CI,3.13-8.18).Basal ganglia and thalamic hemorrhage has strong correlation with hypertension (P<0.001,OR=11.44, 95%CI,4.53-28.88).There was no strong association found between Intracranial hemorrhage and DM (P=0.57,OR=1.2) Conclusion: In our study the prevalence of non traumatic intracranial hemorrhage was shown to be high. Some associated factors identified and HTN was significantly associated with intracranial hemorrhage. Basal ganglia and thalamic hemorrhage was strongly associated with HTN.
