INTRODUCTION Population aging translates into more people with chronic non-communicable diseases, disability, frailty and dependency. The study of frailty-a clinical syndrome associated with an increased risk of falls, disability, hospitalization, institutionalization and death-is important to improve clinical practice and population health indicators. OBJECTIVES In a cohort of older adults in Havana and Matanzas provinces, Cuba, estimate prevalence of frailty and its risk factors; determine incidence of dependency; estimate mortality risk and identify mortality predictors. METHODS A prospective longitudinal study was conducted door to door, from June 2003 through July 2011, in a cohort of 2813 adults aged ?65 years living in selected municipalities of Havana and Matanzas provinces; mean follow-up time was 4.1 years. Independent variables included demographics, behavioral risk factors and socioeconomic indicators, chronic non-communicable diseases (hypertension, stroke, dementia, depression, diabetes, anemia), number of comorbidities, and APOE ?4 genotype. Dependent variables were frailty, dependency and mortality. Criteria for frailty were slow walking speed, exhaustion, weight loss, low physical activity and cognitive decline. Prevalence and frailty risk were estimated by Poisson regression, while dependency and mortality risks and their predictors were determined using Cox regression. RESULTS Frailty syndrome prevalence was 21.6% (CI 17.9%-23.8%) at baseline; it was positively associated with advanced age, anemia and presence of comorbidities (stroke, dementia, depression, three or more physically debilitating diseases). Male sex, higher educational level, married or partnered status, and more household amenities were inversely associated with frailty prevalence. In follow-up, dependency incidence was 33.1 per 1000 person-years (CI 29.1-37.6) and mortality was 55.1 per 1000 person-years. Advanced age, male sex, lower occupational status during productive years, dependency, frailty, dementia, depression, cerebrovacular disease and diabetes were all associated with higher risk of death. CONCLUSIONS Given the challenge for developing countries presented by demographic and epidemiologic transition; the high prevalence in older adults of frailty syndrome, dependency and chronic non-communicable diseases; and the association of all these with higher mortality, attention should be targeted to older adults as a risk group. This should include greater social protection, age-appropriate health services, and modification and control of cardiovascular risk factors. [ABSTRACT FROM AUTHOR]

INTRODUCTION Chronic non-communicable diseases are the leading cause of death worldwide, except in Sub-Saharan Africa. Nonetheless, one of these conditions, dementia, is the major contributor to disability-adjusted life years in people aged ?60 years. Few epidemiological studies exist of the prevalence and impact of dementia and selected chronic diseases in older adults in Latin America. OBJECTIVE Describe prevalence of dementia, other chronic vascular diseases and cardiovascular risk factors, as well as resulting disabilities and care needs generated in adults aged ?65 years in Havana City and Matanzas provinces, Cuba. METHODS The 10/66 study is a prospective longitudinal study involving a cohort of 3015 adults aged ?65 years in municipalities of Havana City and Matanzas provinces, divided into two phases: a cross-sectional door-to-door study conducted in 2003-2006, and a follow-up and assessment phase in 2007-2010. This article reports findings from the first phase. Hypertension diagnosis was based on criteriafrom the International Society for Hypertension; diabetes mellitus on American Diabetes Association criteria; stroke according to WHO definitions; and dementia according to criteria of the American sychiatricSociety's Diagnostic and Statistical Manual of Mental Disorders DSMIV and the 10/66 International Dementia Research Group. Ischemic heart disease was defi ned by self-report of previous physician diagnosis. Study variables included age, sex, educational level, substance use (alcohol, tobacco) and dietary habits. A structured physical and neurological exam, including blood pressure measurement, was performed on all participants. Laboratory tests included complete blood count, fasting blood glucose, total cholesterol and lipoprotein fractions, triglycerides and apolipoprotein E genotype. Prevalence and standardized morbidity ratios (crude and adjusted) were calculated for chronic diseases studied with 95% confi dence intervals, using a Poisson regression model and indirect standardization. RESULTS The study assessed 2944 older adults (response rate 97.6%) and found high prevalence of vascular risk factors and of chronic non-communicable diseases: hypertension 73.0% (95% CI 71.4-74.7), diabetes mellitus 24.8% (95% CI 22.9-26.5), ischemic heart disease 14.1% (95% CI 12.9-15.4), dementia 10.8% (95% CI 9.7-12.0) and stroke 7.8% (95% CI 6.9-8.8). The majority of participants (85%) had more than one cardiovascular risk factor. The main cause of disability and dependency in the study population was dementia. CONCLUSION The high prevalence of chronic diseases observed in the elderly-with the consequent morbidity, disability and dependency- highlights the need for prevention, early diagnosis and risk factor control, particularly given the demographic and epidemiologic transition faced by Cuba and other developing countries.

INTRODUCTION: Cerebrovascular disease (CVD) is the third cause of death and second cause of disability and dementia in adults aged =65 years worldwide. The few epidemiological studies of stroke in Latin America generally report lower prevalence and different patterns than developed countries. OBJECTIVE: Estimate the prevalence of stroke and associated risk factors in adults aged ⩾65 years in Havana City and Matanzas provinces, Cuba. METHODS: Single phase, cross-sectional, door-to-door study of 3015 adults aged ⩾65 years in selected municipalities of Havana City and Matanzas provinces. Variables studied were age, sex, educational level, and self-report and description of chronic disease (stroke, heart attack, angina, and diabetes mellitus), substance use (alcohol, tobacco), and dietary habits. Respondents were given a structured physical and neurological exam, and blood pressure was measured. Laboratory tests comprised complete blood count, fasting glucose, total cholesterol and fractions, triglycerides, and apolipoprotein E (APOE) genotype. Diagnosis of stroke was based on the World Health Organization's defi nition. Stroke prevalence ratios (crude and adjusted), with 95% confi dence intervals (CI), were calculated for the variables studied using a Poisson regression model. Risk association was analyzed using multiple logistic regression for dichotomous responses. RESULTS: Assessments were made of 2944 older adults (97.6% response rate). Prevalence of stroke was 7.8% (95% CI 6.9-8.8), and was higher in men. The risk profi le for this population group included history of hypertension (OR 2.8; 95% CI 2.0-4.0), low HDL cholesterol (OR 2.6; 95% CI 1.7-3.9), male sex (OR 1.7; 95% CI 1.2-2.5), anemia (OR 1.6; 95% CI 1.1-2.5), history of ischemic heart disease (OR 1.5; 95% CI 1.0-2.3), carrier of one or two apolipoprotein E4 genotype (APOE ϵ4) alleles (OR 1.4; 95% CI 1.0-2.0), and advanced age (OR 1.3; 95% CI 1.1-1.9). CONCLUSIONS: Stroke prevalence in this study is similar to that reported for Europe and North America, and higher than that observed in other Latin American countries. The risk profi le identifi ed includes classic risk factors plus anemia and APOE e4 genotype. [ABSTRACT FROM AUTHOR]
