Elderly Mortality from Cerebrovascular Disease in Alagoas, 2000-2016: Spatial-Temporal Analysis

Abstract Background Cerebrovascular diseases (CVDs) are the second leading cause of death in Brazil. Objective This study aimed to describe the epidemiological profile and to analyze the spatiotemporal dynamics of mortality from cerebrovascular disease in the elderly in Alagoas from 2000-2016. Methods This is a multilevel ecological study of all deaths from CVD in individuals aged 60 years or older. Data were collected from the Mortality Information System. The variables were submitted to descriptive analysis, trend analysis by Joinpoint Regression method and spatial analysis with Global Moran's and local statistics; 95% confidence interval and significance of 5% were considered in the analysis. Results There were 21,440 deaths in the study period, 50.4% (n=10,797) male, 40.5% (n=8,670) aged ≥ 80 years, 44.5% (n=9,465) of "brown" race, 30.1% (n=6,448) married and 36.5% (n=7,828) with less than four years of schooling. Female and male mortality rates were 460.24/100,000 and 602.23 / 100,000, respectively. An annual decreasing trend of -1.4% (p<0.001) in overall and male mortality was observed from 2007 on. The highest mortality rates were concentrated in the eastern region of Alagoas (Moran's I =0.766288; p=0.01). Twenty-two municipalities were in quadrant Q1 of Moran's scattering diagram and considered priorities. Conclusion Death from CVD in Alagoas occurred equally in men and women in the study period, mostly in individuals of mixed race, married, and with low education attainment. The highest rates were observed in the eastern region of the state . The results highlight the need for public policies aimed at healthy aging in the state.

Cerebrovascular Diseases and Associated Risk Factors in WHO Eastern Mediterranean Countries.

Background: In the WHO Eastern Mediterranean region, nearly one million deaths are caused by cardio-vascular diseases every year. During the last decade, the number of deaths caused by stroke increased by 23%. Most cardiovascular diseases can be prevented by addressing behavioural risk factors such as tobacco use, alcohol, unhealthy diet, physical inactivity, and metabolic risk factors like obesity, high blood pressure, diabetes and raised lipids. Methods: This is a systematic review on cerebrovascular diseases and associated risk factors in WHO Eastern Mediterranean countries. Medline, Science Direct, and other sources were used to get peer reviewed papers dealing with the review theme. The search was limited to publications between 1990 and 2013 (30th June). Results and Discussion: According to the inclusion criteria, 45 papers were included in the present review. The prevalence was found greater than 50% in 38 studies for hypertension, greater than 25% in 36 studies for diabetes, greater than 15% in 26 studies for smoking and greater than 25% in 19 studies for dyslipidemia. It was also indicated that incidence of stroke increases with ageing. The majority of studies found a prevalence of stroke higher in men than in women with a ratio male: female reaching 3.55:1 in one study. Conclusion: Although at different levels of importance, all the studies reveal that hypertension, diabetes, dyslipidemia and smoking are crucial risk factors for stroke. This review also indicates a lack or scarcity of studies in many countries with an uneven contribution by country since 33% of studies are from Pakistan whereas North Africa (Egypt, Morocco, Libya, Tunisia) contributed with only 2 papers.

Race, gender and stroke subtypes mortality in São Paulo, Brazil

Stroke mortality rates have a discrepant distribution according to socioeconomic variables as social exclusion in Brazil. Recently, data from race has been available from the official health statistics considering five categories: White, Mixed, Black, Asian and Native. We addressed in the city of São Paulo, Brazil, an analysis of cerebrovascular mortality according to race (excluding Asian and Native due to small number of events) and gender during 1999-2001 for people aged 30 to 79 years-old. For all cerebrovascular diseases, age-adjusted mortality rates (x 100,000) for men were higher for Black (150.2), intermediate for Mixed (124.2) and lower for White (104.5) people. These gradient patterns were similar for all stroke subtypes, except for subarachnoideal hemorrhage in which no differences were detected. For women, the rates were lower compared to men and the same pattern was observed among Black (125.4), Mixed (88.5) and White (64.1) women. Compared to White men, the risk ratio of Black men was 1.4. However, compared to White women, the risk ratio for Black women was 2.0. Concluding, there is a significant gradient of stroke mortality according to race, mainly among women.

As taxas de mortalidade pela doença cerebrovascular apresentam distribuição diferenciada de acordo com variáveis socioeconômicas. Informação sobre raça é nova no sistema de informação de mortalidade do Ministério da Saúde. Na cidade de São Paulo foi verificada entre três categoria de raça - branca, parda e negra - a taxa específica de mortalidade nos anos de 1999-2001 para pessoas entre 30 e 79 anos. Para o conjunto das doenças cerebrovasculares as taxas de mortalidade ajustadas para idade (x 100.000) para homens foram maiores entre os negros (150,2), intermediária para os pardos (124,2) e menor para brancos (104,5). Esse gradiente foi o mesmo para todos os subtipos, excluindo a hemorragia subaracnoídea. Para as mulheres, as taxas foram menores quando comparada aos homens e, o mesmo padrão foi observado para negras (125,4), pardas (88,5) e brancas (64,1). A razão de risco para homens negros quando comparado aos brancos foi 1.4, mas entre as mulheres negras e as brancas foi o dobro. Concluindo, houve um gradiente significativo da mortalidade cerebrovascular de acordo com raça, principalmente entre mulheres.
