71 Stroke is the second most common cause of death and a frequent cause of adult disability worldwide [1,2]. There are some countries in which the mortali- ty rates of stroke are particularly high, even in more recent years. This includes Azerbaijan, also [3]. Age is the one of the most important non-mod- ifiable risk factor for stroke, with at least a dou- bling of stroke risk in each decade over age 55 [4]. Some risk factors of stroke are acquired at a younger age (eg, smoking) and thus age can be con- sidered a marker for the duration of exposure to a risk factor, whereas other risk factors tend to become more prevalent with advancing age (eg, hypertension and diabetes) [4]. Men in the United States aged 55 to 64 years were 3 times more likely than men aged 45 to 54 years to have experienced a stroke [5]. The results of Stroke register in Russia showed that, incidence of stroke increased in 30-39 age groups from 0.15‰, to 27.7‰ in age groups >70 [6]. Instead of predicting reduction of incidence about 35% in some developed European countries in future 20 years, in the end of this period due to population aging the number of patient with stroke will increase 11% [6]. The aim of our study was exploring age structure in patients with stroke. Materials and method. We stadied 173 stroke cases which registered in Siyazan region of Azerbaijan using Stroke Registry program dur- ing 3 years (01.01.2007-31.12.2009). Results with CI of 95-99.9% (p<0.05-0.001) were considered statistically significant [7]. Calculations were per- formed in Microsoft Excel spreadsheet. Results. From 173 stroke cases 85 comprised of males (49.1±3.8%) and 88 of females (50.9±3.8%). Age interval of patients was 25-91. Average ages of stroke patients are presented in Table 1. As seen from the Table 1, average ages of stroke cases for the study period did not demonstrate sta- tistically significant differences. Mean age of stroke cases during investigated years was 65.2±0.9. During the study period, men had stroke at a younger age than women (Table 2), with the dif- ference of 9.7%. Patients residing in rural areas had stroke at elder age than urban population, which was at a statistically significant level.

Azerbaijan State Advanced Training Institute forDoctrs, named after A.Aliyev, department of neuro- logy, Baku, Azerbaijan The ame of this study was exploring age as risk factor for stroke among 173 stroke cases which registered during 3 years (01.01.2007- 31.12.2009) in Siyazan region of Azerbaijan. Mean age of stroke cases during investigated years was 65.2±0.9. Males had stroke at a younger age - 62.2±1.3 than females - 68.2±1.2 (p<0.001). Patients residing in rural areas had stroke at older age than urban pop- ulation, which was at a statistically significant level. Most of the stroke patients fell into the age groups of 50-59 and 70-79. In first age group men, in second women. Mean age for ischaemic and hemorrhagic stroke cases was 65.8±0.9 and 57.6±3.4, respectively.
