Birth cohort differences in cardiovascular risk factors in a Brazilian population of older elderly: the Bambuí cohort study of aging (1997 and 2008)

Abstract

The aim of this study was to investigate whether cohort differences exist in the prevalence of cardiovascular risk factors among older elderly from the Bambuí Cohort Study of Aging. Participants were those aged 71-81 years at two points in time a decade apart: 457 in 1997 (earlier cohort) and 553 in 2008 (recent cohort). The prevalence of hypertension (PR = 1.27; 95%CI: 1.19-1.36) and of diabetes mellitus (PR = 1.39; 95%CI: 1.06-1.83) was higher in the recent cohort compared to the earlier one, regardless of sex. The recent cohort had a lower prevalence of smoking (PR = 0.58; 95%CI: 0.42-0.80), and lower total cholesterol/HDL cholesterol ratio level (PR = 0.85; 95%CI: 0.80-0.89). There was a 136% increase in the pharmacologic treatment of diabetes and a 56% increase in pharmacologic management of hypertension in 2008 in comparison with 1997. Overall, the number of cardiovascular risk factors in the recent cohort remained similar to that of the early cohort.

Birth cohort differences in anthropometric measures in the older elderly: the Bambuí cohort study of aging (1997 and 2008)

“…In addition, preliminary information suggests increasing prevalence of arterial hypertension and diabetes mellitus among elderly participants of the recent birth cohort 32 , reinforcing once again the need for further studies directed to understanding the determinants of such trends better. …”

Birth cohort differences in physical functioning levels among elderly Brazilians: findings from the Bambuí cohort study of aging (1997-2008)

“…On the other hand, in the same cohort, there was an increase in the prevalence of both hypertension and diabetes. They also showed higher mean systolic blood pressure and increased body mass index 29,31 . These changes could potentially explain the differences observed in physical functioning levels between the two cohorts.…”

“…One of the differences was an increase in the use of medication by the participants born between 1927 and 1937 compared to those born between 1916 and 1926, especially regarding the use of drugs for the treatment of hypertension, diabetes and hyperdyslipidemia 29,30 . The young cohort had lower levels of smoking, lower mean total cholesterol and lower mean diastolic blood pressure.…”

Prevalence and Clustering of Cardiometabolic Risk Factors in the Elderly Population Living in Rural Areas

“…4 Resultados corroborados em coorte, realizada com idosos em Bambuí-MG, demonstraram que as frequências de diabetes mellitus e hipertensão arterial sistólica aumentam com a idade, além do aumento do tratamento medicamentoso para ambas as doenças. 18 Tabela 2 -Distribuição, RP e intervalo de confiança de 95% dos fatores de risco cardiometabólicos segundo sexo em população rural brasileira No Brasil, em 1994, foi instituída a Política Nacional do Idoso, com o objetivo de assegurar os direitos sociais da pessoa idosa, promovendo a autonomia e a participação efetiva desse grupo na sociedade. Desde então, outras iniciativas foram implementadas, como o Estatuto do Idoso e a Política Nacional de Saúde da Pessoa Idosa.…”

“…5 Essa aglomeração foi maior que em outras pesquisas realizadas com indivíduos com 60 anos ou mais 4,18 . Uma potencial explicação, além dos mecanismos fisiopatológicos para esse achado, pode estar relacionada aos fatores socioeconômicos como pobreza e baixo nível educacional na população estudada e à qualidade dos serviços de atenção à saúde na área rural.…”
