Use of heuristics during the clinical decision process from family care physicians in real conditions.

RATIONALE AIMS AND OBJECTIVES: The available evidence on the use of heuristics and their relationship with diagnostic error in primary care is very limited. The aim of the study is to identify the use of unknown thought and specifically the possible use of Representativeness, Availability and overconfidence heuristics in the clinical practice of primary care physicians in cases of dyspnoea and to analyse their possible relationship with diagnostic error. METHODS: A total of 371 patients consulting with new episodes of dyspnoea in Primary Care centres in Spain were registered. Based on specific operational definitions, the use of unconscious thinking and the use of heuristics during the diagnostic process were assessed. Subsequently, the association between their use and diagnostic error was analysed. RESULTS: In 49.6% of cases, the confirmatory diagnosis coincided with the first diagnostic impression, suggesting the use of the representativeness heuristic in the diagnostic decision process. In 82.3% of the cases, the confirmatory diagnosis was among the three diagnostic hypotheses that were first identified by the general physicians, suggesting a possible use of the availability heuristic. In more than 50% of the cases, the physicians were overconfident in the certainty of their own diagnosis. Finally, a diagnostic error was identified in 9.9% of the recorded cases and no statistically significant correlation was found between the use of some unconscious thinking tools (such as the use of heuristics) and the diagnostic error. CONCLUSION: Unconscious thinking manifested through the acceptance of the first diagnostic impression and the use of heuristics is commonly used by primary care physicians in the clinical decision process in the face of new episodes of dyspnoea; however, its influence on diagnostic error is not significant. The proposed explicit and reproducible methodology may inspire further studies to confirm these results.

The Role of European Schools and University Departments of Public Health in the 2020 COVID-19 Response, European Region, 2020.

Objective: The main objective was to examine, how European Schools of Public Health (SPHs) responded to the COVID-19 pandemic through 2020, across the main activity domains of the SPHs. Methods: A cross-sectional survey based on an online questionnaire concerning the anti-COVID-19 activities from 1st March to 31st October 2020 of the 117 members of the Association of Schools of Public Health in the European Region (ASPHER). The questionnaire asked about 33 sub-themes within the four main themes of teaching, health communication to the public, research, and consultancy/advice. Results: Fifty-nine SPHs (50%) completed the questionnaire. Seventy-nine per cent of participants were involved in COVID-19 related teaching; health communication to the public, 76%; research, 80%; consultancy/advice, 81%. Eight out of ten participants had been involved in all of the four main themes. Conclusion: The study demonstrated a substantial body of COVID-19 related work by SPHs in Europe, and an outstanding potential to deliver crucial knowledge and skills to support the governance and the public health systems necessary to combat COVID-19.

Uso de heurísticos y error diagnóstico en Atención Primaria: revisión panorámica / Effect of the use of heuristics on diagnostic error in Primary Care: Scoping review

OBJETIVO: Evaluar la evidencia sobre el uso de heurísticos de representatividad, disponibilidad, anclaje y ajuste y exceso de confianza en la práctica clínica real, específicamente en el ámbito de la Atención Primaria. DISEÑO: Revisión panorámica (scoping review). Fuentes de datos: Bases de datos de OvidMedline, Scopus, PsycoINFO, Cochrane Library y PubMed. Con el fin de facilitar la comprensión y replicabilidad de los estudios seleccionados se revisaron aplicando los criterios TIDieR (Template for Intervention Description and Replication). Selección de estudios: Se seleccionaron 48 estudios que analizaban heurísticos de disponibilidad (26), anclaje y ajuste (9), exceso de confianza (9) y representatividad (8). RESULTADOS: La población de estudio incluía médicos (35,4%), pacientes (27%), residentes (20,8%), enfermeros (14,5%) y estudiantes (14,5%). Los estudios realizados en condiciones reales fueron 17 (35,4%). En 33 de los 48 estudios se observó el empleo del heurístico analizado en la población estudiada (68,7%). El uso de heurísticos durante el proceso diagnóstico fue analizado en 27 estudios (54,1%); en 5 de ellos, el estudio se realizó en escenarios reales (18%). De los 48 estudios, 6 se realizaron en Atención Primaria (12,5%), 3 de los cuales analizaban el proceso diagnóstico: solo en uno de los 3 se analizó el uso de heurístico en condiciones reales, sin demostrar la existencia de sesgo. CONCLUSIONES: La evidencia empírica disponible sobre la utilización de heurísticos y su papel en el error diagnóstico en condiciones reales es limitada. En particular, en el caso del proceso de decisión diagnóstica en Atención Primaria la evidencia es prácticamente inexistente

OBJECTIVE: To assess the use of representativeness, availability, overconfidence, anchoring and adjustment heuristics in clinical practice, specifically in Primary Care setting. DESIGN: Panoramic review (scope review). Data sources: OvidMedline, Scopus, PsycoINFO, Cochrane Library and PubMed databases. Each one of the selected studies was reviewed applying TIDIER criteria (Template for Description of the Intervention and Replication) to facilitate their understanding and replicability. Selection of studies: A total of 48 studies were selected that analyzed availability heuristics (26), anchoring and adjustment (9), overconfidence (9) and representativeness (8). RESULTS: From the 48 studies selected, 26 analyzed availability heuristics, 9 anchoring and adjustment, 9 overconfidence; and 8 representativeness. The study population included physicians (35.4%), patients (27%), trainees (20.8%), nurses (14.5%) and students (14.5%). The studies conducted in clinical practice setting were 17 (35.4%). In 33 of the 48 studies (68,7%) it was observed heuristic use in the population studied. Heuristics use on diagnostic process was found in 27 studies (54.1%); 5 of them (18%) were carried out in clinical practice setting. Of the 48 studies, 6 (12,5%) were performed in Primary Care, 3 of which studied diagnostic process: only one of them analyzed the use of heuristics in clinical practice setting, without demonstrating bias as consequence of the use of heuristic. CONCLUSION: The evidence about heuristic use in diagnostic process on clinical practice setting is limited, especially in Primary Care

[Sex Differences of Perceived Health before and During the Economic Crisis (2007 and 2011). Spain]. / Diferencias por sexo de la salud percibida antes y durante la crisis económica (2007 y 2011).

OBJECTIVE: Several studies show the association between economic crises, unemployment and health income. However, it is necessary to differentiate their impact according to gender. The objective of this study was to analyze the effect that the economic crisis, unemployment and income may have had on the perceived health of men and women in Spain. METHODS: A cross-sectional study was conducted combining data from the 2007 and 2011 Living Conditions Surveys, which collect data from 43,900 adult individuals up to 65 years of age. A multivariate logistic regression analysis was performed, for the whole population as for each sex. The dependent variable was perceived health and the independent variables were income level, employment status, education level, chronic illness, and the year in which the survey was performed. RESULTS: Perceived health improved over the period under consideration, from 75.1% in 2007 to 83%,0 in 2011. Unemployment significantly increased the chances of reporting perceived bad health in men [OR=1.45; CI95%:1.26-1.67] but not in women [OR=1.20; CI95%:0.99-1.47]. ORs of perceived bad health were higher for women than for men in the lower-income [1.81; IC95%1,56-2,11 against 1.70; IC95%:1,46-1,97. 2011] was related to a lower probability of poor perceived health in both men [OR=0.41, CI95%: 0.37-0.46] and women [OR=0.39 ; CI95%:0.35-0.44]. CONCLUSIONS: The association of the economic crisis with perceived health was similar in men and women. Unemployment was a risk factor for perceived bad health in the case of men. Available income, education level, and the presence of chronic illness had a larger influence as determinants of perceived bad health for women than they did for men.

OBJETIVO: Diversos estudios muestran la asociación entre las crisis económicas, el desempleo y la renta con la salud. Sin embargo, se precisa diferenciar su impacto en función del sexo. El objetivo de este estudio fue analizar el efecto que la crisis económica, el desempleo y la renta pueden haber tenido en la salud percibida de hombres y mujeres en España. METODOS: Se realizó un estudio transversal que combinó las Encuestas de Condiciones de Vida de 2007 y 2011, incluyendo a 43.900 personas adultas de hasta 65 años. Se realizó análisis estratificado y regresión logística multivariante. La variable dependiente fue la salud percibida y las variables independientes la renta, la situación laboral, la educación, la enfermedad crónica y el año de la encuesta. RESULTADOS: La buena salud percibida se incrementó del 75,1 % en 2007 al 83% en 2011. El desempleo se relacionó con mayor probabilidad de mala salud percibida en hombres: OR de 1,45; IC95%:1,26-1,67, mientras que en mujeres las diferencias fueron OR=1,20; IC95%:0,99-1,47. La probabilidad de mala salud percibida fueron mayores para mujeres (OR=1,81; IC95%:1,56-2,11) que para hombres (OR=1,7; IC95%:1,46-1,97). El año 2011 se relacionó con tener menor probabilidad de mala salud percibida tanto en hombres (OR=0,41; IC95%: 0,37-0,46) como en mujeres (OR=0,39; CI95%:0,35-0,44). CONCLUSIONES: La asociación de la crisis económica con la salud percibida fue similar en hombres y mujeres. El desempleo fue un factor de riesgo para la mala salud percibida en hombres mientras que la influencia del nivel de renta, del educativo y la enfermedad crónica fue mayor en mujeres que hombres.

[Characteristics of Hospitalizations of Homeless Persons in Seville, Spain]. / Características de los ingresos hospitalarios de las personas sin hogar en Sevilla.

OBJECTIVE: The aim was to determine the characteristics of hospital admissions of homeless persons in Seville, Spain. METHODS: Observational study of 103,802 hospital admissions of 71,756 patients admitted in the Hospitals "Virgen del Rocío" and "Virgen Macarena" (Seville), in 2013 and 2014. Bivariate analysis were performed using χ2 and t-Student tests and multivariate analysis using binomial logistic regression model. RESULTS: 0.16% (n=163) of admissions were homeless persons and 99.84% (n=103,639) were not. The mean age at admission in homeless patients was 48 years and 76.5% of them were men. Hospital deaths of homeless patients occurred being 23 years younger. 92% of hospital admissions came from emergency departments and 10.0% of their discharges were against medical advice. The average length of stay was 4.8 days longer in homeless persons and the most frequent diagnoses on admission were mental (27.0%), infectious (19.6%) and respiratory diseases (18.4%). Mental disorders were present on 83.7% of homeless patients as secondary diagnose and 77.6% referred drugs consumption. CONCLUSIONS: Hospital admissions characteristics of homeless persons were particularly different. Homeless patients were hospitalized and died at a younger age than non-homeless patients. The morbidity and mortality of homeless persons reflect their vulnerable health condition.

OBJETIVO: El objetivo fue conocer las características de las hospitalizaciones de las personas sin hogar en dos hospitales de Sevilla. METODOS: Estudio observacional de 103.802 hospitalizaciones correspondientes a 71.756 personas ingresadas en los Hospitales Virgen del Rocío y Macarena (2013 y 2014) analizadas en función de si las personas ingresadas tenían o no hogar. Se realizó análisis bivariante y los test χ2 y t-Student análisis multivariante mediante modelos de regresión logística binomial. RESULTADOS: 163 (0,16%) de las hospitalizaciones correspondieron a personas sin hogar y 103.639 (99,84%) a personas con hogar. La edad media de ingreso de las personas sin hogar fue de 48 años, siendo el 76,5% hombres. La mortalidad intrahospitalaria se produjo a una edad media de 23 años menor que la de las personas con hogar (p=0,009). El 92% de sus ingresos fueron urgentes y el 10,0% tuvieron altas voluntarias/fugas. La estancia media en las personas sin hogar fue 4,8 días mayor y sus principales motivos de ingreso fueron enfermedades mentales (27,0%), infecciosas (19,6%) y respiratorias (18,4%). El 83,7% de estas personas presentaron enfermedad mental como comorbilidad y el 77,6% consumía alguna droga, alcohol o tabaco. CONCLUSIONES: Las características de las hospitalizaciones de las personas sin hogar que ingresan en los dos hospitales con mayor actividad asistencial de Sevilla son distintas a las de las personas con hogar. Las personas sin hogar ingresan y fallecen a menor edad. Tanto su patrón de morbilidad como las características de sus hospitalizaciones reflejan su estado vulnerable de salud.

Efectos de la edad, el periodo de defunción y la cohorte de nacimiento en la mortalidad por enfermedad isquémica del corazón en el sur de España / Age, period, and cohort effects on mortality from ischemic heart disease in southern Spain

Introducción y objetivos: La cardiopatía isquémica es la primera causa de muerte y una de las cuatro principales causas de carga de enfermedad en el mundo. El objetivo de este trabajo es evaluar los efectos edad-periodo-cohorte la mortalidad por cardiopatía isquémica en Andalucía (sur de España) y en cada una de sus provincias durante el periodo 1981-2008. Métodos: Se realizó un estudio ecológico poblacional. Se analizaron las 145.539 defunciones por cardiopatía isquémica ocurridas en Andalucía durante el periodo de estudio a edades comprendidas entre 30 y 84 años. Se estimó un modelo de regresión no lineal con funciones spline para cada sexo y área geográfica. Resultados: En la tasa de mortalidad masculina y femenina a partir de 30 años de edad se observa tendencia a aumentar. El riesgo de muerte para varones y mujeres fue descendiente para las cohortes nacidas después de 1920 y con una pendiente más pronunciada después de 1960 entre los varones. El análisis del efecto periodo mostró que el riesgo de mortalidad masculina y femenina se mantuvo estable desde 1981 hasta 1990, aumentó entre 1990 y 2000 y volvió a disminuir desde 2000 hasta 2008. Conclusiones: Los efectos edad-periodo-cohorte en la mortalidad fueron similares en todas las provincias de Andalucía y el conjunto de la comunidad autónoma. Si los efectos cohorte y periodo persisten, la mortalidad masculina y femenina por enfermedad isquémica cardiaca continuará disminuyendo (AU)

Introduction and objectives: Ischemic heart disease is the leading cause of death and one of the top 4 causes of burden of disease worldwide. The aim of this study was to evaluate age-period-cohort effects on mortality from ischemic heart disease in Andalusia (southern Spain) and in each of its 8 provinces during the period 1981-2008. Methods: A population-based ecological study was conducted. In all, 145 539 deaths from ischemic heart disease were analyzed for individuals aged between 30 and 84 years who died in Andalusia in the study period. A nonlinear regression model was estimated for each sex and geographical area using spline functions. Results: There was an upward trend in male and female mortality rate by age from the age of 30 years. The risk of death for men and women showed a downward trend for cohorts born after 1920, decreasing after 1960 with a steep slope among men. Analysis of the period effect showed that male and female death risk first remained steady from 1981 to 1990 and then increased between 1990 and 2000, only to decrease again until 2008. Conclusions: There were similar age-period-cohort effects on mortality in all the provinces of Andalusia and for Andalusia as a whole. If the observed cohort and period effects persist, male and female mortality from ischemic heart disease will continue to decline (AU)

The impact of the economic crisis on unmet dental care needs in Spain.

OBJECTIVES: To analyse the impact that the economic crisis and the evolution of socioeconomic inequality before (2007) and during (2011) the current crisis have had on unmet dental care needs in Spain. METHODS: The Living Conditions Surveys from the years 2007 and 2011 were used, including 44 138 adults aged under 65 years. A descriptive and stratified analysis was carried out along with the calculation of the concentration index and a multivariate logistic regression jointly and separately by gender. The dependent variable was unmet dental care needs and the independent variables were income, employment status, gender, age, education and chronic disease. A dummy variable was created for the year of survey completion as a proxy measure for the economic crisis. The SPSS V.20 software was used. RESULTS: During the period under analysis, the unmet needs for dental services increased (from 6.2% to 7.2%) along with the concentration index (from -0.1412 to -0.189). The main correlations with unmet needs were: unemployment (OR=1.46), lower income (OR=2.44 for the income quintile) and the year 2011 with respect to 2007 (OR 1.13). For women, the OR is greater according to income level (2.44 compared with 1.77 in men) and the year 2011 (1.21 compared with 1.06), while for men unemployment had a greater effect (OR=1.52 compared with 1.46). CONCLUSIONS: There has been an increase in unmet dental care needs as well as in the social gradient for service access. The most vulnerable groups are those with less purchasing power and the unemployed. The economic crisis has also increased this unmet need.

Age, Period, and Cohort Effects on Mortality From Ischemic Heart Disease in Southern Spain.

INTRODUCTION AND OBJECTIVES: Ischemic heart disease is the leading cause of death and one of the top 4 causes of burden of disease worldwide. The aim of this study was to evaluate age-period-cohort effects on mortality from ischemic heart disease in Andalusia (southern Spain) and in each of its 8 provinces during the period 1981-2008. METHODS: A population-based ecological study was conducted. In all, 145 539 deaths from ischemic heart disease were analyzed for individuals aged between 30 and 84 years who died in Andalusia in the study period. A nonlinear regression model was estimated for each sex and geographical area using spline functions. RESULTS: There was an upward trend in male and female mortality rate by age from the age of 30 years. The risk of death for men and women showed a downward trend for cohorts born after 1920, decreasing after 1960 with a steep slope among men. Analysis of the period effect showed that male and female death risk first remained steady from 1981 to 1990 and then increased between 1990 and 2000, only to decrease again until 2008. CONCLUSIONS: There were similar age-period-cohort effects on mortality in all the provinces of Andalusia and for Andalusia as a whole. If the observed cohort and period effects persist, male and female mortality from ischemic heart disease will continue to decline.

Evaluación del impacto en la salud del proyecto de reurbanización de la calle San Fernando en Alcalá de Guadaíra (Sevilla) / Health impact assessment of the San Fernando street renewal project in Alcalá de Guadaíra (Seville, Spain)

Objetivos: Se presenta la experiencia de una evaluación del impacto en la salud realizada en 2010 sobre el proyecto de reurbanización de la calle San Fernando, vía principal de acceso al barrio de San Miguel-El Castillo, en Alcalá de Guadaíra (Sevilla). Constituye ésta una de las primeras actuaciones previstas en el Plan URBAN de regeneración social, urbana y económica del casco histórico del municipio. Métodos: Se han seguido las cinco fases y los procedimientos clásicos de una evaluación del impacto en la salud. La revisión de la evidencia se ha complementado con una consulta a la población afectada en forma de taller participativo, así como con entrevistas a profesionales sociosanitarios con implicación en el barrio. Resultados: Durante las obras, los impactos negativos se relacionan con los efectos nocivos del proyecto sobre la calidad del aire, el nivel de ruidos, las restricciones a la movilidad y el riesgo de siniestralidad, en especial entre la población mayor o con movilidad reducida. Cuando finalicen, se prevén mejoras en determinantes del entorno físico tales como la accesibilidad y la conectividad del barrio con servicios sanitarios y otros bienes y servicios en otras zonas del municipio. También se prevén impactos positivos vinculados a la seguridad y el atractivo del barrio, así como nuevas oportunidades para la sociabilidad, la cohesión social y la autoestima comunitaria. Conclusiones: Se trata de la primera experiencia en Andalucía cuyos resultados se han integrado en un ciclo formal de toma de decisiones de ámbito local. Ello ha permitido valorar el potencial, la aplicabilidad y la aceptación de la evaluación del impacto en la salud en el ámbito municipal, así como facilitar un proceso de aprendizaje y un pilotaje de métodos y herramientas adaptadas (AU)

Objectives: This study describes the design and implementation of a health impact assessment (HIA) conducted in 2010 of the regeneration project of San Fernando Street, the main avenue crossing the San Miguel-El Castillo neighborhood in Alcala de Guadaíra (Seville, Spain). This project is part of the wider URBAN Plan aimed at the social, urban and economic regeneration of the city's historic center. Methods: This experience followed the standard HIA stages and procedures. The review of published evidence was complemented with new qualitative information gathered by means of a participative workshop with the local population and interviews with social and health workers involved in the neighborhood. Results: During the building stage of the project, the adverse impacts were related to a worsening of the air quality, increased noise pollution, mobility restrictions and a higher risk of accidents, particularly among older or disabled people. Once the building stage was finished, the health benefits were associated with significant improvements in physical accessibility and the population's access to health services and other goods and services. Other positive effects were the enhanced safety and attractiveness of the neighborhood and the new opportunities for socializing, social cohesion and increasing the community's self-esteem. Conclusions: This is the first HIA experience in Andalusia whose results have been integrated into a formal cycle of decision making in the local community. This experience has provided new evidence of the potential of HIA and its applicability and acceptance at the municipal level and has has also facilitated a learning process and the piloting of new methods and tools associated with the HIA process (AU)

RESULTS: During the building stage of the project, the adverse impacts were related to a worsening of the air quality, increased noise pollution, mobility restrictions and a higher risk of accidents, particularly among older or disabled people. Once the building stage was finished, the health benefits were associated with significant improvements in physical accessibility and the population's access to health services and other goods and services. Other positive effects were the enhanced safety and attractiveness of the neighborhood and the new opportunities for socializing, social cohesion and increasing the community's self-esteem. CONCLUSIONS: This is the first HIA experience in Andalusia whose results have been integrated into a formal cycle of decision making in the local community. This experience has provided new evidence of the potential of HIA and its applicability and acceptance at the municipal level and has has also facilitated a learning process and the piloting of new methods and tools associated with the HIA process.

Urinary levels of arsenic and heavy metals in children and adolescents living in the industrialised area of Ria of Huelva (SW Spain).

The Ria of Huelva (south-west Spain) is a highly polluted estuary as a consequence of long-term mining and industrial activities. Between 2003 and 2004, we conducted a biomonitoring study of exposure to arsenic and some heavy metals (cadmium, chromium, copper and nickel) in urine samples of a representative sample (n=227) of children and adolescents residing in this area, and of a reference group of 196 children and adolescents living in other less industrialised areas of Andalusia (south Spain). We also assessed the determinants of the variability in urinary metals within the population of the Ria of Huelva. There were no significant differences in the concentration of metal compounds between the two groups with the exception of Cd levels, which were significantly higher in the reference group. Levels of the five metal ions in both groups were generally within the range of values reported by other biomonitoring studies for general children population, although mean Cd levels tended to be higher as compared to other European studies. Among the population of the Ria of Huelva, the main determinants of the interindividual variation in urinary metals were age, sex, area of residence, and frequency of intake of certain food items (mainly fish and shellfish). Overall, results suggest that living in the Ria of Huelva is not increasing current levels of exposure to certain metals among children and adolescents above those found in other urban areas of Andalusia.

Uncontrolled migrations as a cause of inequality in health and mortality in small-area studies.

Mortality is one of the most widely used indicators in small-area ecologic studies. Both accessibility to mortality data and advances in the development of new disease mapping techniques have contributed to an abundance of mortality maps and atlases over the last decade. Results may be biased in this kind of study if there has been unmeasured geographic mobility of the population. Most published papers tend to neglect this possibility. We use the theory of dynamics systems to demonstrate that migratory flows unmonitored by official population registers may lead to major errors in mortality rates and relative risks. Simulations in 4 scenarios showed more than 8% underestimation of the mortality rate and more than 11% underestimation of relative risk in areas with high uncontrolled emigration, and above 19% overestimation of mortality rate and above 15% overestimation of relative risk in areas with high uncontrolled immigration.Researchers conducting small-area epidemiologic studies should explore the reliability of population information in geographic areas before drawing hypothesis or conclusions on other possible causes of mortality differences.

[Interactive mortality atlas in Andalusia, Spain (AIMA)]. / Atlas interactivo de mortalidad en Andalucía (AIMA).

Until now, mortality atlases have been static. Most of them describe the geographical distribution of mortality using count data aggregated over time and standardized mortality rates. However, this methodology has several limitations. Count data aggregated over time produce a bias in the estimation of death rates. Moreover, this practice difficult the study of temporal changes in geographical distribution of mortality. On the other hand, using standardized mortality hamper to check differences in mortality among groups. The Interactive Mortality Atlas in Andalusia (AIMA) is an alternative to conventional static atlases. It is a dynamic Geographical Information System that allows visualizing in web-site more than 12.000 maps and 338.00 graphics related to the spatio-temporal distribution of the main death causes in Andalusia by age and sex groups from 1981. The objective of this paper is to describe the methods used for AIMA development, to show technical specifications and to present their interactivity. The system is available from the link products in www.demap.es. AIMA is the first interactive GIS that have been developed in Spain with these characteristics. Spatio-temporal Hierarchical Bayesian Models were used for statistical data analysis. The results were integrated into web-site using a PHP environment and a dynamic cartography in Flash. Thematic maps in AIMA demonstrate that the geographical distribution of mortality is dynamic, with differences among year, age and sex groups. The information nowadays provided by AIMA and the future updating will contribute to reflect on the past, the present and the future of population health in Andalusia.

Rural habitat and risk of death in small areas of Southern Spain.

The purpose of this paper is to study the linkage between type of habitat and mortality from all causes in small areas of Southern Spain. An ecological study was conducted on 99,870 people who died between 1985 and 1999. The municipality was taken as the unit of analysis. Data analysis was carried out through hierarchical spatio-temporal bayesian models. Results show a 13.3% reduction in mortality rates among men and 14.1% among women in the most rural areas compared to more urban environments. The study demonstrates the usefulness of socio-demographic indices in small-area geographical analyses.

Revisión de los trabajos publicados sobre promoción de la salud en jóvenes españoles / Review of published works on spanish youth health promotion

El objetivo de este estudio ha sido revisar las intervenciones de promoción de la salud dirigidas a jóvenes españoles, publicadas entre los años 1995 y 2000 en español, y describirlas de acuerdo al ámbito en el que se han desarrollado, los temas a los que se han dirigido, la metodología y el diseño de evaluación utilizados y los resultados obtenidos.Se identificaron 214 intervenciones. Las drogas ilegales fueron el tema en el que se centraron el mayor número de intervenciones (29,8 por ciento), seguido por el alcohol (15,9 por ciento), las conductas sexuales de riesgo (14,6 por ciento) y el ocio (12,6 por ciento). Las actividades realizadas con mayor frecuencia fueron: técnicas educativas participativas (30,7 por ciento), técnicas educativas expositivas (11,5 por ciento) y elaboración de materiales educativos (11 por ciento). En el 80,8 por ciento de casos había constancia de que se había realizado una evaluación. De ellas, las más frecuente fueron las evaluaciones de proceso (73,7 por ciento), y las menos frecuente las evaluaciones de resultados a medio-largo plazo (2,2 por ciento). Las metodologías de evaluación más utilizadas fueron los cuestionarios (28,2 por ciento). La combinación de técnicas cualitativas y cuantitativas fue utilizada en el 13,2 por ciento de los casos. Las 4 intervenciones en las que se midió el impacto a medio-largo plazo tenían como objetivo la prevención o reducción del consumo de tabaco y/o alcohol y/o cánnabis, y todas ellas consiguieron reducir el consumo de tabaco.En conclusión, parece necesario mejorar el diseño evaluativo de las intervenciones de promoción de la salud dirigidas a jóvenes en nuestro país y aumentar la difusión de las mismas mediante su publicación (AU)
