We sought to assess (1) the relationship between air particulate pollutants and feto-infant morbidity outcomes and (2) the impact of a Federal Healthy Start program on this relationship. This is a retrospective cohort study using de-identified hospital discharge information linked to vital records, and air pollution data from 2000 through 2007 for the zip codes served by the Central Hillsborough Federal Healthy Start Project in Tampa, Florida. Mathematical modeling was employed to compute minimal Euclidean distances to capture exposure to ambient air particulate matter. The outcomes of interest were low birth weight (LBW), very low birth weight (VLBW), small for gestational age, preterm (PTB), and very preterm birth. We used odds ratios to approximate relative risks. A total of 12,356 live births were analyzed. Overall, women exposed to air particulate pollutants were at elevated risk for LBW (AOR = 1.24; 95% CI = 1.07-1.43), VLBW (AOR = 1.58; 95% CI = 1.09-2.29) and PTB (AOR = 1.18; 95% CI = 1.03-1.34). Analysis by race/ethnicity revealed that the adverse effects of air particulate pollutants were most profound among black infants. Infants of women who received services provided by the Central Hillsborough Federal Healthy Start Project experienced improved feto-infant morbidity outcomes despite exposure to air particulate pollutants. Environmental air pollutants represent important risk factors for adverse birth outcomes, particularly among black women. Multi-level interventional approaches implemented by the Central Hillsborough Federal Healthy Start were found to be associated with reduced likelihood for feto-infant morbidities triggered by exposure to ambient air particulate pollutants.

Objetivos: evaluar la magnitud de la relación entre la dimensión socioeconómica y la dimensión salud en familias pertenecientes a diferentes consultorios del médico y la enfermera de la familia. Métodos: se realizó un estudio transversal en 840 familias pertenecientes a 12 consultorios pertenecientes a siete áreas de salud en La Habana. L a dimensión socioeconómica estuvo representada por condiciones de la vivienda y de la familia, y la de salud por las densidades de hipertensión, diabetes y hábito de fumar. Resultados: no existió asociación entre el nivel de escolaridad y la densidad de diabéticos y fumadores, solo en relación con la hipertensión se apreció algún indicio de asociación lineal con la escolaridad, no hubo indicios de asociación entre las variables de salud y la posesión de equipos de primera y segunda necesidad en la vivienda. Los tres factores de riesgo exhibieron claras tendencias en relación con la percepción de la situación económica. Entre los que aprecian que su condición económica es mala o muy mala, hay densidades altas de las tres entidades, las desigualdades socioeconómicas no se asociaron con la densidad de los factores de riesgo. Conclusiones: la relación entre las desigualdades socioeconómicas y la situación de salud en Cuba es baja.(AU)/ Objectives: to evaluate the relationship of the socioeconomic dimension and the health dimension in Cuban families cared for by several family physician's offices. Methods: a cross-sectional study of 840 families from 12 family physician's offices located in seven health areas of Havana was conducted. The socioeconomic dimension was represented by the conditions of the house and of the family, and the health dimension was represented by the hypertension, diabetes and smoking densities. Results: there was no relation between schooling and the density of diabetics and smokers; just hypertension was observed to have some linear relation with schooling. No signs of association between the variables health and the ownership of first and secondary need appliances at home. The three risk factors exhibited clear tendencies in terms of the perception of economic situation. There exist high densities of the three factors among those who considered their economic conditions as bad or very bad; the socio-economic inequalities had no relation with the density of risk factors. Conclusions: there is low association between socio-economic inequalities and health situation in Cuba.(AU)

OBJECTIVE: To assess the economic cost of routine Aedes aegypti control in an at-risk environment without dengue endemicity and the incremental costs incurred during a sporadic outbreak. METHODS: The study was conducted in 2006 in the city of Guantanamo, Cuba. We took a societal perspective to calculate costs in months without dengue transmission (January-July) and during an outbreak (August-December). Data sources were bookkeeping records, direct observations and interviews. RESULTS: The total economic cost per inhabitant (p.i.) per month. (p.m.) increased from 2.76 USD in months without dengue transmission to 6.05 USD during an outbreak. In months without transmission, the routine Aedes control programme cost 1.67 USD p.i. p.m. Incremental costs during the outbreak were mainly incurred by the population and the primary/secondary level of the healthcare system, hardly by the vector control programme (1.64, 1.44 and 0.21 UDS increment p.i. p.m., respectively). The total cost for managing a hospitalized suspected dengue case was 296.60 USD (62.0% direct medical, 9.0% direct non-medical and 29.0% indirect costs). In both periods, the main cost drivers for the Aedes control programme, the healthcare system and the community were the value of personnel and volunteer time or productivity losses. CONCLUSIONS: Intensive efforts to keep A. aegypti infestation low entail important economic costs for society. When a dengue outbreak does occur eventually, costs increase sharply. In-depth studies should assess which mix of activities and actors could maximize the effectiveness and cost-effectiveness of routine Aedes control and dengue prevention.

During the 1990s, Cuba was able to overcome a severe crisis, almost without negative health impacts. This national retrospective study covering the years 1989-2000 analyses the country's strategy through essential social, demographic, health process and health outcome indicators. Gross domestic product (GDP) diminished by 34.76% between 1989 and 1993. In 1994 slow recuperation started. During the crisis, public health expenses increased. The number of family doctors rose from 9.22 to 27.03 per 104 inhabitants between 1989 and 2000. Infant mortality rate and life expectancy exemplify a series of health indicators that continued to improve during the crisis years, whereas low birth weight and tuberculosis incidence are among the few indicators that suffered deterioration. GDP is inversely related to tuberculosis incidence, whereas the average salary is inversely related to low birth weight. Infant mortality rate has a strong negative correlation with the health expenses per inhabitant, the number of maternal homes, the number of family doctors and the proportion of pregnant women receiving care in maternal homes. Life expectancy has a strong positive correlation with health expenses, the number of nursing personnel and the number of medical contacts per inhabitant. The Cuban strategy effectively resolved health risks during the crisis. In times of serious socio-economic constraints, a well conceptualized public health policy can play an important role in maintaining the overall well-being of a population.

BACKGROUND: Cuban Americans have a high prevalence of type 2 diabetes, placing them at risk for cardiovascular disease (CVD) and increased medical costs. Little is known regarding the lifestyle risk factors of CVD among Cuban Americans. This study investigated modifiable CVD risk factors of Cuban Americans with and without type 2 diabetes. METHODS: Sociodemographics, anthropometrics, blood pressure, physical activity, dietary intake, and biochemical parameters were collected and assessed for n=79 and n=80 Cuban Americans with and without type 2 diabetes. RESULTS: Fourteen percent with diabetes and 24 percent without diabetes engaged in the recommended level of physical activity. Over 90 percent had over the recommended intake of saturated fats. Thirty-five percent were former or current smokers. DISCUSSION: Cuban Americans had several lifestyle factors that are likely to increase the risk of CVD. Their dietary factors were associated with blood cholesterol and body weight, which has been shown to impact on medical expenses. These findings may be used for designing programs for the prevention of CVD as well as type 2 diabetes for Cuban Americans.

BACKGROUND: Results of the few cohort studies from countries with low incomes or middle incomes suggest a lower incidence of dementia than in high-income countries. We assessed incidence of dementia according to criteria from the 10/66 Dementia Research Group and Diagnostic and Statistical Manual of Mental Disorders (DSM) IV, the effect of dementia at baseline on mortality, and the independent effects of age, sex, socioeconomic position, and indicators of cognitive reserve. METHODS: We did a population-based cohort study of all people aged 65 years and older living in urban sites in Cuba, the Dominican Republic, and Venezuela, and rural and urban sites in Peru, Mexico, and China, with ascertainment of incident 10/66 and DSM-IV dementia 3-5 years after cohort inception. We used questionnaires to obtain information about age in years, sex, educational level, literacy, occupational attainment, and number of household assets. We obtained information about mortality from all sites. For participants who had died, we interviewed a friend or relative to ascertain the likelihood that they had dementia before death. FINDINGS: 12,887 participants were interviewed at baseline. 11,718 were free of dementia, of whom 8137 (69%) were reinterviewed, contributing 34,718 person-years of follow-up. Incidence for 10/66 dementia varied between 18·2 and 30·4 per 1000 person-years, and were 1·4-2·7 times higher than were those for DSM-IV dementia (9·9-15·7 per 1000 person-years). Mortality hazards were 1·56-5·69 times higher in individuals with dementia at baseline than in those who were dementia-free. Informant reports suggested a high incidence of dementia before death; overall incidence might be 4-19% higher if these data were included. 10/66 dementia incidence was independently associated with increased age (HR 1·67; 95% CI 1·56-1·79), female sex (0·72; 0·61-0·84), and low education (0·89; 0·81-0·97), but not with occupational attainment (1·04; 0·95-1·13). INTERPRETATION: Our results provide supportive evidence for the cognitive reserve hypothesis, showing that in middle-income countries as in high-income countries, education, literacy, verbal fluency, and motor sequencing confer substantial protection against the onset of dementia.

OBJECTIVE: To describe the current situation and trends in mortality due to cardiovascular disease (CVD) in the Americas and explore their association with economic indicators. DESIGN AND SETTING: This time series study analysed mortality data from 21 countries in the region of the Americas from 2000 to the latest available year. MAIN OUTCOMES MEASURES: Age-adjusted death rates, annual variation in death rates. Regression analysis was used to estimate the annual variation and the association between age-adjusted rates and country income. RESULTS: Currently, CVD comprised 33.7% of all deaths in the Americas. Rates were higher in Guyana (292/100 000), Trinidad and Tobago (289/100 000) and Venezuela (246/100 000), and lower in Canada (108/100 000), Puerto Rico (121/100 000) and Chile (125/100 000). Male rates were higher than female rates in all countries. The trend analysis showed that CVD death rates in the Americas declined -19% overall (-20% among women and -18% among men). Most countries had a significant annual decline, except Guatemala, Guyana, Suriname, Paraguay and Panama. The largest annual declines were observed in Canada (-4.8%), the USA (-3.9%) and Puerto Rico (-3.6%). Minor declines were in Mexico (-0.8%) and Cuba (-1.1%). Compared with high-income countries the difference between the median of death rates in lower middle-income countries was 56.7% higher and between upper middle-income countries was 20.6% higher. CONCLUSIONS: CVD death rates have been decreasing in most countries in the Americas. Considerable disparities still remain in the current rates and trends.

Large-scale use and acceptance of homeopathy in Cuba, Latin America, and India raises questions about the relevance of campaigns mounted against homeopathy in the United Kingdom, Australia, and other nations of the developed world, especially as the developing economies of Asia and Latin America are set to outstrip those of the developed world.

In December 2011, the first delegation of oncology nurses from the United States visited Havana, Cuba. The delegation included oncology nurses, educators, and leaders from across America and provided opportunities to learn about the healthcare system, cancer, and oncology nursing in Cuba. Delegation members attended lectures, toured facilities, and enjoyed Cuban culture. This exchange highlighted the similarities in cancer care and oncology nursing between countries and opened doors for future collaborations.
