How is smoking distributed in relation to socioeconomic status? Evidence from Brazil in the years 2013 and 2019.

The present study aimed to analyze income-related inequality in tobacco consumption in Brazil using data from the National Health Survey at two points in time (2013 and 2019). This study contributes to the growing literature analyzing socioeconomic inequalities in tobacco use by investigating income-related inequalities in the consumption of different tobacco products in Brazil. The inequality measure is the concentration index with an Erreygers correction (EI), and the analysis of its decomposition allows the identification of the factors that determine such inequality. There is inequality in smoking concentrated in the poorest persons, and this pattern also occurs for manufactured cigarettes and roll-your-own cigarettes (RYO), while inequality in smoking cessation is concentrated among the wealthiest. Smoking inequalities were greater in men, older age groups, and RYO. In terms of evolution, the overall results indicated a small decline in smoking inequality. For the decomposition analysis, the results show that the main factors that affect tobacco inequality in terms of concentration in the poorest are education, income, and having private health insurance. The region variable, by contrast, has a positive contribution, since the wealthiest regions have individuals who are more likely to smoke. These results have important implications that serve as a basis for formulating public health policies. For example, greater inequalities for men and older individuals can be targeted by public policies with a special focus on these cases.

Acesso para quem quer ou para quem pode? Equidade na utilização de consultas médicas em Portugal com base no INS 2019 / Access for those who want or for those who can? Equity in the use of doctor's appointments in Portugal based on the HIS 2019

Resumo A equidade horizontal no uso de cuidados de saúde requer igual uso para igual necessidade, independentemente de outros fatores - predisponentes ou de capacitação (modelo de Andersen). O objetivo é avaliar a equidade no uso de consultas médicas em Portugal em 2019, comparando os resultados com os obtidos em estudo anterior, com dados de 2014. Os dados vêm do Inquérito Nacional de Saúde 2019. O uso de cuidados é medido pelo número de consultas. Para avaliar as determinantes da utilização, adota-se o modelo binomial negativo. Para quantificar a desigualdade/iniquidade relacionada com o rendimento, calcula-se o índice de concentração. Face a 2014, os efeitos do estado de saúde autoavaliado, limitação nas atividades diárias e problema de saúde prolongado são mais pronunciados e, a região, rendimento, tipo de agregado e estado civil são significativos, nas consultas de medicina geral e familiar. Nas outras consultas, o seguro perdeu significância estatística e o efeito educação foi atenuado, mas emergiu um efeito rendimento. O índice de iniquidade não é significativo nas consultas de medicina geral e familiar, como em 2014, mas o valor (significativo) desse índice aumentou para as consultas de outras especialidades.

Abstract Horizontal equity in the use of healthcare implies equal use for equal needs, regardless of other factors - be they predisposing or enabling (Andersen's model). This study aimed to assess equity in the use of doctor's appointments in Portugal in 2019, comparing the results with those obtained in a previous study, based on data from 2014. Data were retrieved from the Health Interview Survey 2019 (HIS 2019). Healthcare is measured by the number of doctor's appointments. Our study adopted the Negative Binomial Model to assess the factors affecting use. The concentration index was calculated to quantify income-related inequality/inequity. Compared to 2014, the effects of self-assessed health, limitations in daily living activities, and longstanding illnesses are more pronounced, and the region, income, household type and marital status are significant for appointments scheduled with a General Practitioner. In the case of appointments with specialists, health insurance lost statistical significance and the effect of education dropped; however, income became significant. The inequity index is not significant for appointments scheduled with a General Practitioner, as in 2014, but the (significant) value of this index increased for appointments with other specialists.

Health-related quality of life by household income in Chile: a concentration index decomposition analysis.

BACKGROUND: Health inequities have a profound impact on all dimensions of people's lives, with invariably worse results among the most disadvantaged, transforming them into a more fragile and vulnerable population. These unfair inequalities also affect dimensions focused on subjectivity, such as health-related quality of life (HRQoL), which has been positioned, in recent decades, as an important outcome in health decision-making. The main objective of this study is to estimate socioeconomic inequality in HRQoL of Chilean by household income.  METHODS: Secondary analysis of the National Health Survey (ENS 2016-2017, Chile). This survey includes a nationally representative, stratified, and multistage household sample of people aged 15 and above. Socioeconomic inequality in HRQoL (EQ5D) is estimated by the concentration index (CI) ranked by household income. Decomposition analysis is conducted to examine potential explanatory sociodemographic factors.  RESULTS: The CI for household income inequality in HRQoL was -0.063. The lower the household income, the worse the HRQoL reported by in Chile. The decomposition analysis revealed that socioeconomic position contributes 75,7% to inequality in the quality of life, followed by educational level (21.8%), female gender (17.3%), and type of Health Insurance (15%), age (-19.7%) and residence (-10.8%). Less than 1% corresponds to the unexplained residual component. CONCLUSIONS: Our findings suggest the existence of a disproportionate concentration of worse HRQoL in the most disadvantaged socioeconomic groups in Chile. This inequality is largely, yet not completely, associated with household income. Other significant factors associated with this inequality are education, gender, and healthcare insurance. These results suggest the need of strengthening efforts to reducing socioeconomic gaps in health outcomes in Chile, as a means to achieve social justice and equity in health and healthcare.

Socioeconomic inequalities in health care utilization in Paraguay: Description of trends from 1999 to 2018.

OBJECTIVE: Paraguay's health care system is characterized by segmented provision and low public spending, with limited coverage and asymmetries in terms of access and quality of care. The present study provides national estimates of income-related inequality in health care utilization and trends in the country over the past two decades. METHODS: Using data from the Paraguayan Permanent Household Survey, we estimated socioeconomic inequality in health care use during the period 1999-2018. We used poverty-to-income ratio as the socioeconomic stratifier and defined health care use as having reported a health problem and subsequent health care use in the last 90 days before interview. Inequality was summarized by rank- and level-based versions of the Concentration Index for binary outcomes. RESULTS: Inequalities affecting those with lower incomes were present in all years assessed, although the magnitude of these inequalities declined over time. Inequality as expressed by the rank-based index decreased from 0.209 (95%CI 0.164; 0.253) in 1999 to 0.032 (95%CI -0.010; 0.075) in 2018. The level-based index decreased from 0.076 (95%CI -0.029; 0.182) in 1999 to 0.024 (0.002; 0.045) in 2018. Trends in both indices were generally stable from 1999 to 2009, with a noticeable decrease in 2010. The sharpest decreases relative to the 1999 baseline were observed in the period 2010-2018, reflecting changes in health care use and income distribution. Stratification by area, sex and older people suggest similar trends within subgroups. CONCLUSIONS: Decreases in inequality coincide temporally with increments in public health expenditure, removal of user fees in public health care facilities and the expansion of conditional cash-transfer programmes. Future research should disentangle the role of each of these policies in explaining the trends described.

Socioeconomic inequality in health in older adults in Brazil.

Objective: This study analyzed socioeconomic inequality in self-rated health for older adults (aged fifty or over) in Brazil. Methods: Data from the 2015-2016 Brazilian Longitudinal Study of Aging (ELSI-Brazil). Socioeconomic inequality in self-rated health was measured using the concentration index, which was decomposed to analyze the contribution of different factors. Results: This study revealed that 11.5% of the older adults interviewed reported their health as poor and very poor. For the complete sample, the estimated concentration index, -0.2434, indicated that there is a concentration of poor and very poor self-rated health among older and poorer adults. Income, education and having a private health insurance plan are the factors that contributed most to the observed inequality. Discussion: The decomposition showed that there are avoidable inequalities in relation to socioeconomic status for older adults in Brazil. These factors can guide the formulation of social and health policies aimed at reducing health inequalities.

Structural elucidation, mechanism of action, antibacterial proficiency and synergistic forte of purified Euphorbia hirta whole plant extract against multi-drug resistant otitis media infection / Elucidación estructural, mecanismo de acción, competencia antibacteriana y fuerza sinérgica del extracto de planta entera de Euphorbia hirta purificado contra la infección por otitis media resistente a múltiples fármacos

This study investigated the antibacterial potential of Euphorbia hirtawhole plant extracts, honey and conventional antibiotics and their synergistic effects against selected multidrug resistant and typed bacterial strains associated with otitis media. E. hirtawhole plant extract was purified using column chromatography technique. The antibacterial assays of extracts were done using standard microbiological procedures. Protein, sodium and potassium ion leakage of the synergistic mixtures was determined using flame-photometry.

Socioeconomic inequalities in alcohol consumption in Argentina: Comparative analysis from 2009, 2013, and 2018.

BACKGROUND: The present study investigates the socioeconomic inequalities in alcohol use and harmful drinking in Argentina, a middle-income beer- and wine-producing country with high levels of alcohol consumption. METHODS: Data from the last three waves (2009, 2013, and 2018) of the National Risk Factors Survey were used. Each wave comprised samples of 34,732, 32,365, and 29,224 individuals, respectively. Outcome measures included the prevalence of alcohol use and heavy episodic drinking (HED). The Erreygers concentration index was employed to measure the socioeconomic inequalities. RESULTS: HED prevalence among drinkers increased from 17 % in 2009 to 25 % in 2018. Overall, the results showed significant pro-rich inequality for alcohol use and pro-poor inequality for HED, indicating that while a smaller proportion of the most disadvantaged population consumed alcohol, harmful drinking tended to concentrate among them. Pro-rich inequality for alcohol use was deeper in the population aged 25+, particularly among women. HED among males aged 35+ showed the highest inequality against lower income groups. During the period analyzed, the group aged 18-24 years had the highest HED prevalence as well as the greatest increase in this measure; it tended to be equally distributed across socioeconomic groups, presenting no socioeconomic inequality by 2018. CONCLUSIONS: These results highlight the importance of the assessment and characterization of the most exposed population to alcohol and harmful drinking. Regardless of their socioeconomic status, the young population was identified as a group for targeted interventions because of its greater alcohol exposure and the potential growth in economic and social burdens.

Antenatal care in Southern Brazil: Coverage, trends and inequalities.

We described prenatal care quality for four indicators over a 12-years period among puerperae living in Southern Brazil. Five surveys including all women giving birth between 01/01 to 31/12 in 2007, 2010, 2013, 2016, and 2019 were conducted in Rio Grande, Rio Grande do Sul state, Brazil. A single standardized questionnaire was applied within 48 h after delivery in all the city's maternity hospitals. Outcomes included the followings proportion of pregnant women who started prenatal care in the first trimester and performed at least six medical visits, completed at least two HIV, two syphilis and two qualitative urine tests. These indicators were stratified according to quartiles of household income. Absolute and relative measures of inequalities were calculated. A total of 12,645 (98% of the total) of the 12,914 mothers eligible in the five surveys were successfully interviewed. Coverage for all indicators increased substantially, especially in the poorest quartile for six prenatal care visits starting in the first trimester, and for HIV and qualitative urine tests. The slope index (SII) and the concentration index (CIX) of inequality showed clear disadvantage among the poorest for prenatal visits starting in the first trimester and performing two or more urine tests. There was a substantial increase in coverage for all variables studied in the period. The reduced inequity, mainly for the beginning of the first trimester and for visits and urine tests, was due to the higher coverage achieved in the poorest quartile.

Spatiotemporal distribution and socioeconomic disparities of dengue, chikungunya and Zika in two Latin American cities from 2007 to 2017.

OBJECTIVE: To assess the presence, pattern and magnitude of socioeconomic inequalities on dengue, chikungunya and Zika in Latin America, accounting for their spatiotemporal distribution. METHODS: Using longitudinal surveillance data (reported arboviruses) from Fortaleza, Brazil and Medellin, Colombia (2007-2017), we fit Bayesian hierarchical models with structured random effects to estimate: (i) spatiotemporally adjusted incidence rates; (ii) Relative Concentration Index and Absolute Concentration Index of inequality; (iii) temporal trends in RCIs; and (iv) socioeconomic-specific estimates of disease distribution. The spatial analysis was conducted at the neighbourhood level (urban settings). The socioeconomic measures were the median monthly household income (MMHI) for Brazil and the Socio-Economic Strata index (SES) in Colombia. RESULTS: There were 281 426 notified arboviral cases in Fortaleza and 40 887 in Medellin. We observed greater concentration of dengue among residents of low socioeconomic neighbourhoods in both cities: Relative Concentration Index = -0.12 (95% CI = -0.13, -0.10) in Fortaleza and Relative Concentration Index = -0.04 (95% CI = -0.05, -0.03) in Medellin. The magnitude of inequalities varied over time across sites and was larger during outbreaks. We identified a non-monotonic association between disease rates and socioeconomic measures, especially for chikungunya, that changed over time. The Relative Concentration Index and Absolute Concentration Index showed few if any inequalities for Zika. The socioeconomic-specific model showed increased disease rates at MMHI below US$400 in Brazil and at SES-index below level four, in Colombia. CONCLUSIONS: We provide robust quantitative estimates of socioeconomic inequalities in arboviruses for two Latin American cities. Our findings could inform policymaking by identifying spatial hotspots for arboviruses and targeting strategies to decrease disparities at the local level.

Horizontal inequity in the use and access to health care in Uruguay.

BACKGROUND: In 2007 Uruguay began a reform in the health sector towards the construction of a National Integrated Health System (SNIS), based on public insurance with private and public provision. The main objective of the reform was to universalize access to health services. METHODS: Data comes from the first National Health Survey conducted in 2014 and available since 2016. Concentration indices are calculated for different indicators of use and access to medical services, for the population 18 years of age and older, and for different subgroups (age, sex, region and type of coverage). The indices are decomposed into need and non-need variables and the contribution of each of them to total inequality is analyzed. Horizontal inequity is calculated. RESULTS: Results show pro-rich inequality for medical consultations, medical analysis, medication use and non-access due to costs. Type of health coverage is the variable that explains most of the inequality: private coverage is pro-rich while public coverage is pro-poor. Income does not appear as significant to explain inequality, except for access issues. From the population subgroups' analysis, there is no evidence of inequality for the group of 60 years old or more. On the other hand, studies such as Pap Smear and prostate, which may be associated with preventive studies,, shows pro-rich inequality and, in both cases, the main contribution is given by income. CONCLUSIONS: The analysis of health inequity shows pro-rich inequity in medical consultations, medical analysis, medication use and lack of access due to costs. The type of health coverage explains these inequalities; in particular, private coverage is pro-rich. These results suggest that the type of health coverage are capturing the income factor, since higher income individuals will be more likely to be treated in the private system.

Synergic effect of simvastatin in combination with amphotericin B against environmental strains of Cryptococcus neoformans from northeastern Brazil: a prospective experimental study

BACKGROUND: Statins are used as cholesterol-lowering drugs and may also have direct antimicrobial effects. OBJECTIVE: To evaluate synergic interactions between simvastatin and both amphotericin B and fluconazole, against environmental strains of Cryptococcus neoformans isolated from captive birds' droppings. DESIGNAND SETTING: Experimental study conducted at Federal University of Piauí, Parnaíba, in collaboration with Federal University of Triângulo Mineiro, Uberaba, Brazil. METHODS: Statin susceptibility tests of Cryptococcus neoformans samples were performed as prescribed in standards. Interactions of simvastatin with amphotericin and fluconazole were evaluated using the checkerboard microdilution method. Presence of these interactions was quantitatively detected through determining the fractional inhibitory concentration index (FICI). RESULTS: Isolates of Cryptococcus neoformans were obtained from 30 of the 206 samples of dry bird excreta (14.5%) that were collected from pet shops and houses. Ten isolates were selected for susceptibility tests. All of them were susceptible to amphotericin and fluconazole. All presented minimum inhibitory concentration (MIC) > 128 µg/ml and, thus, were resistant in vitro to simvastatin. An in vitro synergic effect was shown through combined testing of amphotericin B and simvastatin, such that six isolates (60%) presented FICI < 0.500. Two isolates showed considerable reductions in MIC, from 1 µg/ml to 0.250 µg/ml. No synergic effect was observed through combining fluconazole and simvastatin. CONCLUSION: These results demonstrate that simvastatin should be considered to be a therapeutic alternative, capable of potentiating the action of amphotericin B. However, further studies are necessary to clarify the real effect of simvastatin as an antifungal agent.

Equity of access to maternal health interventions in Brazil and Colombia: a retrospective study.

BACKGROUND: Reducing maternal mortality is a top priority in Latin American countries. Despite the progress in maternal mortality reduction, Brazil and Colombia still lag behind countries at similar levels of development. METHODS: Using data from the Demographic Health Survey, this study quantified and compared, by means of concentration indices, the socioeconomic-related inequity in access to four key maternal health interventions in Brazil and Colombia. Decomposition analysis of the concentration index was used for two indicators - skilled attendance at birth and postnatal care in Brazil. RESULTS: Coverage levels of the four key maternal health interventions were similar in the two countries. More specifically, we found that coverage of some of the interventions (e.g. ante-natal care and skilled birth assistance) was higher than 90% in both countries. Nevertheless, the concentration index analysis pointed to significant pro-rich inequities in access in all four key interventions in both countries. Interestingly, the analysis showed that Colombia fared slightly better than Brazil in terms of equity in access of the interventions studied. Finally, the decomposition analysis for the presence of a skilled attendant at birth and postnatal care in Brazil underlined the significance of regional disparities, wealth inequalities, inequalities in access to private hospitals, and inequalities in access to private health insurance. CONCLUSIONS: There are persistent pro-rich inequities in access to four maternal health interventions in both Brazil and Colombia. The decomposition analysis conducted on Brazilian data suggests the existence of disparities in system capacity and quality of care between the private and the public health services, resulting in inequities of access to maternal health services.

Socioeconomic inequalities in alcohol consumption in Chile and Finland.

BACKGROUND: Reasons for socioeconomic inequalities in alcohol harm are not sufficiently understood. One explanation relates to differential exposure to alcohol by socioeconomic status (SES). The present study investigated socioeconomic inequalities in alcohol use in two countries with high alcohol consumption and alcohol harm. METHODS: Data from nationally representative surveys in 2009-2010 in Chile and in 2008-2011 in Finland were used. Surveys comprised 3477 participants in Chile and 9994 in Finland aged 30-64 years. Outcome measures included abstinence, weekly consumption of pure alcohol, heavy volume drinking and heavy episodic drinking (HED). We employed a novel method in alcohol research, the concentration index, to measure socioeconomic inequalities. RESULTS: Alcohol abstinence showed a strong association with lower SES in Chile and Finland. These were largely driven by inequalities among women in Chile and older subgroups in Finland. In both countries, women aged 45-64 of higher SES showed higher weekly consumption of pure alcohol and heavy volume drinking. Heavy volume drinking among Chilean women aged 45-64 showed the highest inequality, favouring higher SES. HED was equally distributed among SES groups in Chile; in Finland HED disproportionally affected lower SES groups. CONCLUSIONS: Lower SES was associated with higher abstinence rates in both countries and heavy episodic drinking in Finland. Heavy volume drinking was more prevalent in middle-aged women of high SES. The results identified groups for targeted interventions, including middle-aged higher SES women, who traditionally have not been specifically targeted. The concentration index could be a useful measure of inequalities in alcohol use.

Antibacterial effect of crude methanol Carica papaya L. (papaya) extract and amoxicillin combination

Background: the emergence of multi-drug resistant bacteria and the diseases caused by them are a serious threat to global health necessitating an urgent need for new approaches to combat them. Synergy studies of conventional antimicrobial drugs and medicinal plants with antibacterial effects are important to establish whether it is prudent to recommend their concurrent administration to get successful treatments. Objective: evaluate the antibacterial effect resulting from the combination of Carica papaya (papaya) and amoxicillin. Methods: the papaya methanol extract was obtained from seeds and phytochemical screening was done. Checkerboard assay was used to determine the Minimum Inhibitory Concentration. Combined effect of both Carica papaya methanol extract and amoxicillin was determined by calculating the Fractional Inhibitory Concentration index. Strains of Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 were used in the tests. Results: phenols and tannins were found in the Carica papaya seed methanol extract. The minimum inhibitory concentration of Carica papaya extract was 100 µg/mL for both microorganisms studied which was higher than the Minimum Inhibitory Concentration of amoxicillin being 3.12 µg/mL for Escherichia coli and 0.2 µg/mL for Staphylococcus aureus. The Fractional Inhibitory Concentration of the combination of drugs was 0.99 for Escherichia coli and 2.51 for Staphylococcus aureus. Conclusions: the antibacterial effect of Carica papaya extract may be attributed to the presence of phenolic compounds. There was no interaction between amoxicillin and Carica papaya extract on Staphylococcus aureus, but the antimicrobial activity against Escherichia coli of both drugs can be potentiated by their additive interaction(AU)

Introducción: la creciente multi-resistencia bacteriana y emergencia de enfermedades causadas por estas bacterias, constituyen un serio problema global, por lo que es importante y urgente el desarrollo de nuevas propuestas terapéuticas para combatirlas. Estudios sinérgicos sobre la combinación de antimicrobianos convencionales y plantas con efectos antibacterianos son importantes para determinar si es aconsejable la administración concomitante de los mismos. Objetivo: evaluar el efecto antibacteriano de la combinación de Carica papaya (papaya) y amoxicilina. Método: fueron usadas semillas de papaya para obtener el extracto alcohólico de papaya y realizado el estudio fitoquímico. La Concentración Mínima Inhibitoria fue determinada por el método del tablero de ajedrez. La Concentración Inhibitoria Fraccionada se calculó para medir el posible efecto sinérgico de la combinación entre el extracto alcohólico de Carica papaya y la amoxicilina. Cepas de Staphylococcus aureus ATCC 25923 y Escherichia coli ATCC 25922 fueron usadas. Resultados: en el extracto alcohólico de papaya fueron encontrados fenoles y taninos. La Concentración Mínima Inhibitoria del extracto de papaya coincidió para ambos microorganismos (100 µg/mL), la cual fue mayor que la Concentración Mínima Inhibitoria de la amoxicilina, siendo 3.125 µg/mL para Escherichia coli y 0.2 µg/mL para Staphylococcus aureus. La Concentración Inhibitoria Fraccionada de la combinación de drogas, fue 0.99 para Escherichia coli y 2.51 para Staphylococcus aureus. Conclusiones: los compuestos fenólicos presentes en el extracto de papaya pueden ser responsables de su efecto antimicrobiano. No existe interacción entre la amoxicilina y el extracto metanólico de papaya contra Staphylococcus aureus. Sin embargo, la actividad antomicrobiana contra Escherichia coli puede ser potenciada por su interacción aditiva(AU)

ß-Lapachone activity in synergy with conventional antimicrobials against methicillin resistant Staphylococcus aureus strains.

The aim of this study was to evaluate the antimicrobial activity of lapachol, α-lapachone, ß-lapachone and six antimicrobials (ampicillin, amoxicillin/clavulanic acid, cefoxitin, gentamicin, ciprofloxacin and meropenem) against twelve strains of Staphylococcus aureus from which resistance phenotypes were previously determined by the disk diffusion method. Five S. aureus strains (LFBM 01, LFBM 26, LFBM 28, LFBM 31 and LFBM 33) showed resistance to all antimicrobial agents tested and were selected for the study of the interaction between ß-lapachone and antimicrobial agents, busing checkerboard method. The criteria used to evaluate the synergistic activity were defined by the Fractional Inhibitory Concentration Index (FICI). Among the naphthoquinones, ß-lapachone was the most effective against S. aureus strains. FICI values ranged from 0.07 to 0.5, suggesting a synergistic interaction against multidrug resistant S. aureus (MRSA) strains. An additive effect was observed with the combination ß-lapachone/ciprofloxacin against the LFBM 33 strain. The combination of ß-lapachone with cefoxitin showed no added benefit against LFBM 31 and LFBM 33 strains. This study demonstrated that, in general, ß-lapachone combined with beta lactams antimicrobials, fluoroquinolones and carbapenems acts synergistically inhibiting MRSA strains.

Diferenciales de salud y una aproximación mediante el empleo del coeficiente de Gini y el índice de concentración en las provincias cubanas, 2002-2008 / Health's differentials and a approaching to use of Gini's coefficient and the rate of concentration in the Cuban provinces, 2002-2008

INTRODUCCIÓN: No existen muchas publicaciones científicas que aborden los diferenciales de salud entre las provincias de Cuba, ni que documenten los principales factores que impactaron en los resultados de salud de la población durante el período 1989-2000. En el año 2002 Fidel Castro destacó la existencia de una serie de errores de conducción y organización durante ese periodo, que a su criterio debilitaron el sistema de salud cubano y propiciaron la aparición de determinadas desigualdades. OBJETIVO: Describir los principales diferenciales de salud existentes entre los distintos territorios de Cuba (factores determinantes de la salud de los cubanos) durante el período estudiado (2002-2008). MÉTODOS: Se utilizó como unidad geográfica a la provincia. Las catorce provincias cubanas fueron estratificadas sobre la base de tres ejes fundamentales: demográfico, económico y condiciones de vida, con vista a identificar posibles diferenciales de salud (inequidades en salud y en servicios de salud) mediante el empleo de la técnica del coeficiente de Gini y del índice de concentración. RESULTADOS: Se muestran los principales factores o variables con diferenciales de salud presentes en el país por provincias durante el período estudiado, se identificaron los factores o variables que mayores diferenciales exhibieron por cada uno de los ejes demográfico (densidad poblacional), económico (producción mercantil) y condiciones de vida (cobertura sanitaria). Se definen las diferencias existentes entre cada una de las provincias y por regiones y las características muy particulares de la capital cubana como provincia. CONCLUSIONES: Se confirma la hipótesis de que a pesar de la férrea voluntad política del estado de evitar inequidades en salud, aún se observan diferenciales no importantes en el comportamiento de las variables estudiadas por cada uno de los ejes de análisis entre provincias. No obstante, existen diferencias entre el comportamiento de esos ...(AU)

INTRODUCTION: There is a lack of scientific publications approaching the health differentials among the Cuban provinces and of to document the leading factors with impact on the health results in the population during the period 1989-2000. In 2002 Fidel Castro Rus emphasized on the existence of errors in the management and organization during above mentioned period, that according to his criterion to weaken the Cuban health system and led to appearance of determined inequalities. OBJECTIVE: To describe the leading health differentials present among the different Cuban territories (determinant health factors for Cubans) during the study period (2002-2008). METHODS: The province was used as geographical unit. The fourteen Cuban provinces were stratified on the base of the three fundamental bases: demographic, economic and life conditions to identify the potential health differentials (inequalities in health and in its services) using the Gini's coefficient technique and the concentration's index. RESULTS: The leading factors or variables with health differentials present in our country by provinces during the study period are showed, identifying the factors or variables with greater differentials by each of the demographic bases (population density), economic (commercial production) and life conditions (health coverage). The differences present among each of the provinces and regions are defined as well as the very particular characteristics of the Cuban capital as province. CONCLUSIONS: The hypothesis that despite the strong political and state will to avoid health inequalities, still there are no-significant differences in the behavior of study variables by each of the bases of analysis among provinces. Nevertheless, there differences among the behavior of such differentials according to analysis's bases, features that be and were considered during the process of health politics design, of reorganization of health services, of human ...(AU)

INTRODUCTION: There is a lack of scientific publications approaching the health differentials among the Cuban provinces and of to document the leading factors with impact on the health results in the population during the period 1989-2000. In 2002 Fidel Castro Rus emphasized on the existence of errors in the management and organization during above mentioned period, that according to his criterion to weaken the Cuban health system and led to appearance of "determined inequalities". OBJECTIVE: To describe the leading health differentials present among the different Cuban territories (determinant health factors for Cubans) during the study period (2002-2008). METHODS: The province was used as geographical unit. The fourteen Cuban provinces were stratified on the base of the three fundamental bases: demographic, economic and life conditions to identify the potential health differentials (inequalities in health and in its services) using the Gini's coefficient technique and the concentration's index. RESULTS: The leading factors or variables with health differentials present in our country by provinces during the study period are showed, identifying the factors or variables with greater differentials by each of the demographic bases (population density), economic (commercial production) and life conditions (health coverage). The differences present among each of the provinces and regions are defined as well as the very particular characteristics of the Cuban capital as province. CONCLUSIONS: The hypothesis that despite the strong political and state will to avoid health inequalities, still there are no-significant differences in the behavior of study variables by each of the bases of analysis among provinces. Nevertheless, there differences among the behavior of such differentials according to analysis's bases, features that be and were considered during the process of health politics design, of reorganization of health services, of human resource training and the intersectorial approach of non-health physicians determinants during the more hard year of special period, confirming the theoretical model previously developed by the authors.
