Impacto económico del tabaquismo en los sistemas de salud de América Latina: un estudio en siete países y su extrapolación a nivel regional./ [Financial impact of smoking on health systems in Latin America: A study of seven countries and extrapolation to the regional level].
| Idioma(s): Español
Objective: Estimate smoking-attributable direct medical costs in Latin American health systems. Methods: A microsimulation model was used to quantify financial impact of cardiovascular and cerebrovascular disease, chronic obstructive pulmonary disease (COPD), pneumonia, lung cancer, and nine other neoplasms. A systematic search for epidemiological data and event costs was carried out. The model was calibrated and validated for Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, and Peru, countries that account for 78% of Latin America's population; the results were then extrapolated to the regional level. Results: Every year, smoking is responsible for 33 576 billion dollars in direct costs to health systems. This amounts to 0.7% of the region's gross domestic product (GDP) and 8.3% of its health budget. Cardiovascular disease, COPD, and cancer were responsible for 30.3%, 26.9%, and 23.7% of these expenditures, respectively. Smoking-attributable costs ranged from 0.4% (Mexico and Peru) to 0.9% (Chile) of GDP and from 5.2% (Brazil) to 12.7% (Bolivia) of health expenditures. In the region, tax revenues from cigarette sales barely cover 37% of smoking-attributable health expenditures (8.1% in Bolivia and 67.3% in Argentina). Conclusions: Smoking is responsible for a significant proportion of health spending in Latin America, and tax revenues from cigarette sales are far from covering it. The region's countries should seriously consider stronger measures, such as an increase in tobacco taxes.
Evaluación de una intervención educativa nutricional en trabajadores de la construcción para prevenir enfermedades crónicas no transmisibles en Chile./ [Assessment of a nutrition education intervention among construction workers].
| Idioma(s): Español
BACKGROUND: Unhealthy lifestyles and overweight are common among blue collar workers. AIM: To evaluate a nutrition education intervention in construction workers to prevent chronic diseases. MATERIAL AND METHODS: One hundred forty two participants were randomly assigned to an experimental group (n = 69) and or a control group (n = 73). The experimental group received nutrition education consisting in individual lifestyle counseling, group workshop, group counseling in healthy lifestyles, and environmental intervention. At baseline and after one year of intervention, clinical evaluations consisting in laboratory determinations, anthropometry and nutritional assessment evaluation were carried out. RESULTS: The experimental group experienced a significant decrease in waist circumference, total cholesterol, triglycerides, and an increase in HDL cholesterol. A significant reduction in total calorie intake, especially at the evening snack was observed during week-days. The same reduction in total calories occurred at dinner during the week-end. A significant increase was observed in the consumption of fruits, vegetables and fish. In the control group there was a significant increase in weight, waist circumference, body mass index, glucose and insulin, without changes in total calorie intake or healthy food consumption. High soft drink consumption did not change in both groups. CONCLUSIONS: In construction workers, integral nutrition intervention at the individual, group and environmental level had an impact in nutritional and biochemical indicators.

Alarmingly high rates of disease-related malnutrition have persisted in hospitals of both emerging and industrialized nations over the past 2 decades, despite marked advances in medical care over this same interval. In Latin American hospitals, the numbers are particularly striking; disease-related malnutrition has been reported in nearly 50% of adult patients in Argentina, Brazil, Chile, Costa Rica, Cuba, Dominican Republic, Ecuador, Mexico, Panama, Paraguay, Peru, Puerto Rico, Venezuela, and Uruguay. The tolls of disease-related malnutrition are high in both human and financial terms-increased infectious complications, higher incidence of pressure ulcers, longer hospital stays, more frequent readmissions, greater costs of care, and increased risk of death. In an effort to draw attention to malnutrition in Latin American healthcare, a feedM.E. Latin American Study Group was formed to extend the reach and support the educational efforts of the feedM.E. Global Study Group. In this article, the feedM.E. Latin American Study Group shows that malnutrition incurs excessive costs to the healthcare systems, and the study group also presents evidence of how appropriate nutrition care can improve patients' clinical outcomes and lower healthcare costs. To achieve the benefits of nutrition for health throughout Latin America, the article presents feedM.E.'s simple and effective Nutrition Care Pathway in English and Spanish as a way to facilitate its use.
A comprehensive assessment of arsenic in commonly consumed foodstuffs to evaluate the potential health risk in Bangladesh.
| Idioma(s): Inglés
Arsenic (As), particularly of its inorganic form (iAs) is highly toxic, and its presence in food composites is a matter of concern for the public health safety, specifically in Bangladesh which is regarded as the most arsenic affected country throughout the world. This study was carried out to investigate the levels of As in the composite samples of commonly consumed foodstuffs collected from 30 different agro-ecological zones for the first time in Bangladesh. Most of the individual food composites contain a considerable amount of As which was, as a whole, in the range of 0.077-1.5mg/kg fw which was lower than those reported from Spain, EU, France, Korea, whereas higher than those of Mexico, Chile, Japan, Cambodia, Hong Kong, Serbia, respectively. Cereals, vegetables, milk, and fish contribute about 90% to the daily intake of inorganic arsenic. Human health risk of dietary iAs was assessed separately for both the rural and urban adults. The estimated daily dietary intakes (EDI) of iAs for the exposed rural (3.5) and urban residents (3.2 µg/kg-BW/day) clearly exceeded the previous provisional tolerable daily intake (PTDI) value of 2.1 µg/kg-BW/day, recommended by the World Health Organization (WHO). From the health point of view, this study concluded that both the rural and urban residents of Bangladesh are exposed to carcinogenic and non-carcinogenic risks who consume As-contaminated water and foodstuffs.

BACKGROUND: Chile has recently been reclassified by the World Bank from an upper-middle-income country to a high-income country. There has been great progress in the last 20 to 30 years in relation to air and water pollution in Chile. Yet after 25 years of unrestrained growth, there remain clear challenges posed by air and water pollution, as well as climate change. OBJECTIVE: The aim of this study was to review environmental health in Chile. METHODS: In late 2013, a 3-day workshop on environmental health was held in Santiago, Chile, bringing together researchers and government policymakers. As a follow-up to that workshop, here we review the progress made in environmental health in the past 20 to 30 years and discuss the challenges of the future. We focus on air and water pollution and climate change, which we believe are among the most important areas of environmental health in Chile. RESULTS: Air pollution in some cities remains among the highest in the continent. Potable water is generally available, but weak state supervision has led to serious outbreaks of infectious disease and ongoing issues with arsenic exposure in some regions. Climate change modeling in Chile is quite sophisticated, and a number of the impacts of climate change can be reasonably predicted in terms of which areas of the country are most likely to be affected by increased temperature and decreased availability of water, as well as expansion of vector territory. Some health effects, including changes in vector-borne diseases and excess heat mortality, can be predicted. However, there has yet to be an integration of such research with government planning. CONCLUSIONS: Although great progress has been made, currently there are a number of problems. We suspect that the Chilean experience in environmental health may be of some use for other Latin American countries with rapid economic development.
Salud ambiental infantil en el contexto de la reubicación de familias de campamentos a viviendas sociales./ [Child health environment in the context of relocating of camp site families to social housing].

INTRODUCTION: Housing interventions aimed at overcoming poverty can lead to changes in the health status of children by modifying risk factors in their physical and social environment OBJECTIVE: the aim was to identify children's environmental health factors to change with the relocation of families from slums to public housing. SUBJECTS AND METHOD: A cross-sectional study was conducted in children ages 2-8 years old of families relocated to public housing (n=115) who were compared to children residing in slums (n=88) in Santiago, Chile. Family socioeconomic characteristics, indoor environment and neighborhoods were collected. It was included respiratory symptoms, accidents and maternal-child care of children. χ2, Fisher and Mann-Whitney test were used to compare groups. RESULTS: There were differences in households related to pets keeping, presence of humidity/molds in homes, types of fuels, and perceived safety problems in neighborhoods (p<0.05). The families from slums reported higher tenancy of pets (73.8% v/s 32.2%%), humidity/molds in homes (43.,2% v/s 18.3%), use of wood for heating (39.8% v/s 0.0%), compared with families of public housing. Residents of public housing perceived more safety problems in neighborhood, and children have more asthma related symptoms and have lower diversity of accidents in home. CONCLUSION: Among the factors studied, indoor air quality and safety in neighborhoods could be linked to changes from the relocation of families. This reinforces the need to deepen the positive and negative influences of residential mobility of these groups focused on child welfare perspective.

| Idioma(s): Español
Measles, one of most important inmuno-preventable diseases, remains as a worldwide concern issue with an important morbidity and mortality. Particularly in the America region declared free of measles in 2010 by WHO, they still appear imported cases that origin outbreaks of variable magnitude in susceptible subjects usually none vaccinated which is the current situation in Santiago, the capital city of Chile. In this review we present characteristics of the etiological agent, the disease, epidemiological aspects with national historical focus, impact of immunization programs and outbreaks in Chile, in order to contribute to knowledge and management of this always present public health problem. Sarampión una de las más importantes enfermedades inmuno-prevenibles, se mantiene como foco de preocupación en el mundo, con elevada carga de morbilidad y mortalidad. Particularmente en América, región declarada libre de esta enfermedad en 2010 por la OMS, se siguen identificando casos importados que originan brotes de diferente magnitud en personas susceptibles, habitualmente no vacunados, situación recientemente diagnosticada en Santiago, ciudad capital de Chile. En esta revisión, se presenta características del agente etiológico, de la enfermedad, aspectos epidemiológicos con foco en datos históricos nacionales, el impacto de los programas de vacunación, la ocurrencia de brotes en Chile, para contribuir al conocimiento y enfrentamiento de este siempre presente problema de salud pública.

Estudio exploratorio del impacto del alfabetismo funcional sobre conductas sanitarias deficientes a nivel poblacional/ An exploratory study of functional literacy on health care behaviors in Chile
| Idioma(s): Español
Background: Health Literacy is the set of skills that constitute the ability to perform reading and numerical tasks to function in the health care environment. People with functional illiteracy are unable to understand written documents and therefore sanitary information. Aim: To explore the effects of functional illiteracy on personal health care behaviors in Chile. Material and Methods: Using the Chilean Social Characterization Survey of 2006, respondents were separated into those that had read a book in the last year and those that had not as a proxy variable for functional literacy. Using econometric models, the impact of this variable on having a Papanicolaou (PAP) smear done and consulting in primary health clinics rather than in emergency services, was explored. Results: The survey is nationally representative, and 76% interviewees declared not having read a book in the last year. Probability of having a PAP smear done during the last three years was higher among women who had read a book with an OR of 1.19 (1.15-1.25). Likewise, the probability of consulting in emergency services rather than in primary health clinics was lower among those who had read a book with an OR of 0.85 (0.80-0.91). Conclusions: This study provides evidence of possible impacts of low functional literacy in health care behaviors in the Chilean population.

The most important event in Chilean public health in the XXth Century was the creation of the National Health Service (NHS), in 1952. Systematic public policies for the promotion of health, disease prevention, medical care, and rehabilitation were implemented, while a number of more specific programs were introduced, such as those on infant malnutrition, complementary infant feeding, medical control of pregnant women and healthy infants, infant and adult vaccination, and essential sanitation services. In 1981, a parallel private health care system was introduced in the form of medical care financial institutions, which today cover 15% of the population, as contrasted with the public system, which covers about 80%. From 1952 to 2014, public health care policies made possible a remarkable improvement in Chile s health indexes: downward trends in infant mortality rate (from 117.8 to 7.2 x 1,000 live births), maternal mortality (from 276 to 18.5 x 100,000), undernourished children < 5 years old (from 63% to 0.5%); and upward trends in life expectancy at birth (from 50 to 79,8 years), professional hospital care of births (from 35% to 99.8%), access to drinking water (from 52% to 99%), and access to sanitary sewer (from 21% to 98.9%). This went hand in hand with an improvement in economic and social indexes: per capita income at purchasing power parity increased from US$ 3,827 to US$ 20,894 and poverty decreased from 60% to 14.4% of the population. Related indexes such as illiteracy, average schooling, and years of primary school education, were significantly improved as well. Nevertheless, compared with OECD countries, Chile has a relatively low public investment in health (45.7% of total national investment), a deficit in the number of physicians (1.7 x 1,000 inhabitants) and nurses (4.8 x 1,000), in the number of hospital beds (2.1 x 1,000), and in the availability of generic drugs in the market (30%). Chile and the USA are the two OECD countries with the lowest public investment in health. A generalized dissatisfaction with the current Chilean health care model and the need of the vast majority of the population for timely access to acceptable quality medical care are powerful arguments which point to the need for a universal public health care system. The significant increase in public expenditure on health care which such a system would demand requires a sustainable growth of the Chilean economy.
