“…In most industrialized countries, downward trends of CVD mortality have been observed over the past few decades [2,6], with the decrease being most marked in Japan. Recent decreasing trends in CVD mortality have also been observed in newly industrialized or developing areas, in-Yu/Tse/Wong/Wong cluding Taiwan and Shanghai, China, Singapore and Spain [7][8][9][10]. The exact reason for this decline remains unknown.…”

This study describes the time trend of cerebrovascular disease (CVD) mortality during the period 1976–1995 in Hong Kong and explores the period and birth cohort effects using Poisson regression models with correction for overdispersion of data. A clear downward trend was observed for age-adjusted CVD mortality rate in both sexes. It decreased from 84 per 100,000 to 41 per 100,000 among men (a 51% drop), and from 56 per 100,000 to 35 per 100,000 among women (a 38% drop). The rate of decline was in general greater in the second decade and among males, resulting in a significant downward trend for the male-to-female rate ratio. Both the period of death and the birth cohort showed a significant effect on the reduction in mortality rates, but the latter seemed to have a more substantial influence. However, an increasing trend was observed among younger males in the second decade, and the protective cohort effect seemed to be waning for the more recent cohorts in both sexes. Closer monitoring of the situation in the next years is warranted.

“…The results showed that the majority of the successive generations in Belgrade had an increasing risk of death from stroke in more recent cohorts, especially among females. The inverse cohort effect existed for several other populations in previous studies [6,7,8] and can be interpreted as a reduction in exposure to risk factors for stroke. Although the last two decades were a period of sharp socioeconomic crisis in Serbia, with a deep influence on the increase in general mortality [13], the major known risk factors for stroke likely had an important influence on changes in lifestyle within generations.…”

“…The age-period analysis of mortality time trends measures the component attributed to the birth cohort and the risk of dying in circumstances prevailing at the time of death, i.e., the period effect. These factors include the short-term effects of primary and secondary prevention, changes in diagnostic procedures and modifications in cause-of-death coding practices [6]. Conversely, the cohort effect relates to lifelong exposure to risk factors shared by the whole generation [7, 8].…”

Objective: To assess the age, period, and cohort effects on stroke mortality in Belgrade, Serbia, between 1989 and 2003. Methods: Mortality data for stroke events were obtained from the Municipal Institute of Statistics. The age- and gender-specific mortality rates were calculated for the cohorts of individuals born between 1904–1908 and 1964–1968. Results: In males, the average mortality rate increased from 80.9/100,000 in 1989–1993 to 111.3/100,000 in 1994–1998, and decreased slightly to 101.8/100,000 in 1999–2003. A similar pattern was observed among females. Stroke mortality risk was strongly related to age in both genders. This age effect was present for both genders, independent of the cohort or time period. The majority of the successive generations in Belgrade had an increased risk of death from stroke in the recent cohorts especially among females. Conclusions: Our results suggest the need to improve efforts in the primary and secondary prevention of stroke.

“…In Lithuanian hospitals since 1990 availability of qualified medical attention and better medical technologies were implemented and may explain a substantial improvement in case-fatality and subsequent declining period effect. These results were supported by another study [18] in which from the mid1980s stroke incidence, particularly among more recent generations, has ceased to decrease and/or has been increasing in other western European countries and New Zealand [19,20]. Possible reasons for this rise lie in increasing survival from diabetes and heart disease, the drift toward healthier diets, and decreasing prevalence of hypertension and smoking [21].…”

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.
