“…14,34 The case-fatality trends were declining in most studies, during the last decades, but in a minority they were stable. 33 More recent studies of case-fatality at 28 or 30 days have also shown declining 14,15 or stable 10 trends. In the Framingham study the incidence of stroke has decreased during the last 50 years for men and women, but the 30-day case-fatality decreased significantly only among men.…”

“…The temporal trends of stroke epidemiology have been studied in Sweden [1][2][3][4] and other countries during the last decades, [5][6][7][8][9][10][11][12][13][14][15][16][17] but although stroke mortality has decreased for many decades, stroke incidence trends have been more divergent. As the elderly population is growing in the developed countries and stroke incidence is much higher among the elderly, time trends for stroke incidence are important in planning of health strategies and to evaluate primary and secondary preventive measures.…”

Background and Purpose— We report trends of stroke incidence and survival up to year 2001/2002 in Lund-Orup, Sweden, and projections of future stroke incidence in Sweden. Methods— Lund Stroke Register, a prospective population-based study, included all first-ever stroke patients, between March 1, 2001 and February 28, 2002, in the Lund-Orup health care district. Institution-based studies for 1983 to 1985 and 1993 to 1995 were used for comparison. We calculated age-standardized incidence and Cox proportional hazards analysis of survival (stroke subtype, sex, age group, and study period in the analysis). Minimum follow-up was 46 months. Based on our register’s stroke incidence and the official Swedish population projection, a projection for future stroke incidence on a national basis was calculated. Results— We included 456 patients with first-ever stroke in 2001/2002. The age-standardized incidence (to the European population) was 144 per 100 000 person-years (95%CI 130 to 158) in 2001/2002, 158 (95%CI 149 to 168) in 1993 to 1995, and 134 (95%CI 126 to 143) in 1983 to 1985. Cox proportional hazard analysis indicated decreased risk of death after stroke in 2001/2002 (hazard ratio 0.80; 95%CI 0.67 to 0.94) compared with 1993 to 1995. Up to year 2050, the annual number of new stroke patients in Sweden may increase by 59% based solely on demographic changes. Conclusions— Despite possible underestimation of stroke incidence during the previous institution-based studies, the increased stroke incidence between 1983 to 1985 and 1993 to 1995 did not continue in 2001/2002. The long-term survival after stroke continues to improve. As the elderly population is growing in Sweden, stable incidence and increasing survival will result in a rapidly increasing prevalence of stroke patients in Sweden.

“…Centers within different countries were selected based on previous experience in running population-based or hospital-based stroke registers. In Kaunas, Lithuania, 13 Dijon, France, 7 London, UK, 11 and Warsaw, Poland, 14 well-established population-based stroke registers have been running since 1986,1982,1995, and 1991, respectively. In Menorca, Spain, and Sesto Fiorentino, Italy, hospitalbased stroke registers were initiated for 2 previous European Union Biomedicine and Health Programme (BIOMED) II Projects starting from 1993 15,16 and for this study, population-based registers were established in both centers.…”

Background and Purpose-Comparable data on stroke incidence across European countries are lacking because previous studies have used different methods of case ascertainment, different periods of observation, and different age restrictions. Methods-Population-based stroke registers were established in 6 European countries: France (Dijon); Italy (Sesto Fiorentino); Lithuania (Kaunas); the United Kingdom (London); Spain (Menorca); and Poland (Warsaw). Standardized criteria were used among these register including overlapping sources of notification. Overall, a source population of 1 087 048 inhabitants was observed, ranging from 47 236 in Sesto Fiorentino to 365 191 in Kaunas. All patients with first-ever stroke of all age groups from the source populations were included. Data collection took part between 2004 and 2006; 4 centers collected data for a 24-month and 2 for a 12-month time period. Crude annual incidence rates were age-adjusted to the European population. Results-A total of 2129 patients with first stroke were registered. Median age was 73 years and 51% were female. Annual stroke incidence adjusted to the European population was found in men to be higher in Kaunas and lower in Sesto Fiorentino and Menorca and in women to be higher in Kaunas and Warsaw and lower in Sesto Fiorentino and Menorca compared with mean incidence rates. Total stroke incidence ranged in men from 101.2 per 100 000 (95% CI, 82.5 to 123.0) in Sesto Fiorentino to 239.3 per 100 000 (95% CI, 209.9 to 271.6) in Kaunas and in women from 63.0 per 100 000 (95% CI, 48.5 to 80.7) in Sesto Fiorentino to 158.7 per 100 000 (95% CI, 135.0 to 185.4) in Kaunas. Differences in prior-to-stroke risk factors were found among the populations with prevalence of hypertension highest in Warsaw and Kaunas (76% and 67%, respectively) and lowest in Menorca and Sesto Fiorentino (54% and 62%, respectively). Conclusions-The risk of stroke among European populations in our study varied more than 2-fold in men and women.On average, higher rates of stroke were observed in eastern and lower rates in southern European countries. Key Words: Europe Ⅲ incidence Ⅲ stroke G eographic comparisons of stroke incidence within countries and between countries are valuable for identifying high-risk populations and for generating new hypotheses for defining preventive interventions. 1,2 Population-based stroke registers are perceived as the gold standard for measuring stroke incidence in the population. 3,4 However, comparability of data on stroke incidence based on previous populationbased registers in Europe is limited for several reasons. Population-based registers need to demonstrate adherence to standardized criteria for producing comparable results. 5,6 Thus, comparability of results with previous studies might be hampered by several methodological differences in data collection. 1 In addition, the incidence of stroke shows substantial variations over time with decline in stroke incidence until the early 1980s, a stabilization or an increase in stroke incidence in the late 1...

“…The stroke events were associated with high blood pressure and diabetes in Pacific women [10]. In Lithuania case fatality significantly decreased both among men and women and incidence of stroke significantly increased among women during 1986-2002 [11]. Declining case fatality can result from better medical management or a change in the severity of stroke.…”

AbstractThe main purpose of this paper was to assess the effects of age, period, and cohort on stroke mortality among the urban Lithuanian population. Routine stroke mortality data among the Lithuanian urban population aged 25–64 years (1041 men and 724 women) between 1980 and 2004 were obtained from the official Kaunas region mortality register and classified by codes 430–438 and 160–169 in the 9th and 10th revisions of the International Classifications of Diseases (ICD), respectively. Mortality rates per 100,000 persons for men and women were age-adjusted using the age distribution of the European Standard Population. Goodness of fit of the Poisson regression models was evaluated using the Pearson and Freeman-Tukey residuals. During the study period, mortality rates decreased from 46.8 to 33.0 per 100,000 for men, and from 20.2 to 18.1 per 100,000 for women (average annual decrease of −1.3%, p<0.1 for men, and −1.6%, p<0.03 for women). An age effect was present in both sexes. The definite upward period effect was observed from 1990 to 1994 both among men and women, and was followed by a sharp fall during 2000–2004. Cohort and period effects have contained relevant information that partially explained trends in stroke mortality among 25–64 year-olds in the Lithuanian urban population. The Poisson regression models could be applied for the examination and explanation of the different causes of the population mortality.
