Urban environment and health: a cross-sectional multiregional project based on population health surveys in Spain (DAS-EP project) - study protocol.

INTRODUCTION: The European Environment Agency estimates that 75% of the European population lives in cities. Despite the many advantages of city life, the risks and challenges to health arising from urbanisation need to be addressed in order to tackle the growing burden of disease and health inequalities in cities. This study, Urban environment and health: a cross-sectional multiregional project based on population health surveys in Spain (DAS-EP project), aims to investigate the complex association between the urban environmental exposures (UrbEEs) and health. METHODS AND ANALYSIS: DAS-EP is a Spanish multiregional cross-sectional project that combines population health surveys (PHS) and geographical information systems (GIS) allowing to collect rich individual-level data from 17 000 adult citizens participating in the PHS conducted in the autonomous regions of the Basque Country, Andalusia, and the Valencian Community, and the city of Barcelona in the years 2021-2023. This study focuses on the population living in cities or metropolitan areas with more than 100 000 inhabitants. UrbEEs are described by objective estimates at participants' home addresses by GIS, and subjective indicators present in PHS. The health outcomes included in the PHS and selected for this study are self-perceived health (general and mental), prevalence of chronic mental disorders, health-related quality of life, consumption of medication for common mental disorders and sleep quality. We aim to further understand the direct and indirect effects between UrbEEs and health, as well as to estimate the impact at the population level, taking respondents' sociodemographic and socioeconomic characteristics, and lifestyle into consideration. ETHICS AND DISSEMINATION: The study was approved by the regional Research Ethics Committee of the Basque Country (Ethics Committee for Research Involving Medicinal Products in the Basque Country; PI2022138), Andalusia (Biomedical Research Ethics Committee of the Province of Granada; 2078-N-22), Barcelona (CEIC-PSMar; 2022/10667) and the Valencian Community (Ethics Committee for Clinical Research of the Directorate General of Public Health and Center for Advanced Research in Public Health; 20221125/04). The results will be communicated to the general population, health professionals, and institutions through conferences, reports and scientific articles.

Did psychotropic drug consumption increase during the 2008 financial crisis? A cross-sectional population-based study in Spain.

OBJECTIVES AND SETTING: Although psychotropic drugs are used to treat mental health disorders, little evidence analyses the effects the 2008 economic downturn had on psychotropic drug consumption in the case of Spain. We analyse these effects, considering both gender and employment situation. PARTICIPANTS: We used the microdata from the face-to-face cross-sectional population-based Spanish National Health Survey for two periods: 2006-2007 (n=28 954) and 2011-2012 (n=20 509). Our samples included adults (>15 years old). METHODS: The response variables are consumption (or not) of antidepressants or sedatives and the explanatory variables are the year of the survey, gender and employment status. Covariates are mental health problems, mental health index General Health Questionnaire (GHQ-12) and self-reported health outcome variables such as self-rated health, chronic diseases, smoking behaviour, sleeping hours, body mass index, physical activity in the workplace, medical visits during the past year, age, region of residence (autonomous communities), educational level, marital status and social class of the reference person. Finally, we include interactions between time period, gender and employment status. We specify random effects logistic regressions and use Bayesian methods for the inference. RESULTS: The economic crisis did not significantly change the probability of taking antidepressant drugs (OR=0.56, 95% CI 0.18 to 2.56) nor sedatives (OR=1.21, 95% CI 0.26 to 5.49). In general, the probability of consuming antidepressants among men and women decreases, but there are differences depending on employment status. The probability of consuming sedatives also depends on the employment status. CONCLUSIONS: While the year of the financial crisis is not associated with the consumption of antidepressants nor sedatives, it has widened the gap in consumption differences between men and women. Although antidepressant use dropped, the difference in consumption levels between men and women grew significantly among the retired, and in the case of sedatives, risk of women taking sedatives increased in all groups except students.

[Impact of disabling chronic pain: results of a cross-sectional population study with face-to-face interview]. / Impacto del dolor crónico discapacitante: resultados de un estudio poblacional transversal con entrevista cara a cara.

OBJECTIVE: To assess the impact of disabling chronic pain (DCP) on quality of life, work, consumption of medication and usage of health services. DESIGN: Cross-sectional population study with face-to-face interview. SETTING: Andalusian Health Survey (2011 edition). PARTICIPANTS: 6,507 people over the age of 16 (p=q=0.5; confidence level=95%; sampling error=1.49, design effect=1.52). INTERVENTIONS: Not applicable. MAIN MEASUREMENTS: Dependent variable: DCP: population limited in their activity by any of the CP specified in the survey. INDEPENDENT VARIABLES: quality of life, absence from work, consumption of medication and utilization of health services. RESULTS: Compared to a population without CP, DCP impact is 6 points less on the mental quality of life and 12 points on the physical one, medication consumption is triple, health services utilization is almost double, and long absence from work is triple. On the other hand, a population with nondisabling chronic pain (nDCP) presents similar results to a population without CP. CONCLUSIONS: We have considered DCP as another CP category because of its huge impact, as is shown in our study, on the study variables. On the contrary, the population with nDCP does not obtain significant impact differences when compared to the population without CP. Therefore, we believe that Primary Care and Public Health should lead different prevention strategies for DCP as well as for the identification of the nDCP population to decrease its possible deterioration towards DCP.

[Comparability of the editions 2006/07 and 2011/12 of the Spanish Health Survey.] / Comparabilidad de las ediciones 2006/07 y 2011/12 de la Encuesta Nacional de Salud de España.

OBJECTIVE: The Spanish Health Survey (SHS) is one of the main sources on social determinants of health. The objectives were to describe the data merging process of the 2006/07 and 2011/12 SHS editions, as well as to provide the merged databases and the directory of the variables. METHODS: The comparable variables were identified from the questionnaires. Other new variables were created to achieve comparability or to provide new indicators of interest. We obtained two completed merged databases, as well as two variable directories with their dictionaries (each one for the adults and children samples). RESULTS: 188 variables were identified as potentially comparable ones. 36,7% of them had difficulties for being comparable and 8% had to be removed. The topic with the worst consequences due to the lack of comparability was the working conditions and employment from the adult sample. CONCLUSIONS: The merging of both SHS editions had a lot of problems, especially in the adult's sample. That affects to its comparability. This work may be useful to assess, design and merge these and other editions of the SHS, as well as to serve as a model to be applied in other cross-sectional population-based surveys.

OBJETIVO: La Encuesta Nacional de Salud de España (ENSE) es una de las fuentes principales sobre determinantes sociales de la salud. Los objetivos de este trabajo fueron describir el procedimiento de fusión de las ediciones 2006/07 y 2011/12 de la ENSE, y proporcionar acceso libre a las bases de datos y directorio de variables. METODOS: Identificamos las variables comparables a partir de los cuestionarios, construyendo otras nuevas para conseguir la comparabilidad o para proporcionar nuevos indicadores de interés. Obtuvimos dos bases de datos fusionadas y dos directorios de variables con sus diccionarios (muestra de adultos y de menores). RESULTADOS: Identificamos 188 variables potencialmente comparables. Un 36,7% tuvieron algún problema para su comparabilidad y un 8% tuvieron que ser eliminadas, fundamentalmente en la muestra de adultos. El ámbito con peores consecuencias de la falta de comparabilidad fue el de condiciones de trabajo y empleo en la muestra de adultos. CONCLUSIONES: La fusión de ambas ediciones de la ENSE tuvo muchas incidencias en la muestra de adultos, afectando de manera importante a su comparabilidad. Este trabajo es útil para evaluar, diseñar y fusionar estas y otras ediciones de la ENSE, e incluso sirve como modelo para la fusión de otras encuestas transversales de base poblacional.

[Care costs and activity in the last three months of life of cancer patients who died in the Basque Country (Spain)]. / Actividad asistencial y costes en los últimos 3 meses de vida de pacientes fallecidos con cáncer en Euskadi.

OBJECTIVE: To analyse the use of health resources and its budget in the last months of life of the population who died from malignant neoplasm in the Basque Autonomous Country (Spain). METHOD: Retrospective observational study of a population with a diagnosis of malignancy deceased in the Basque Country (2010 and 2011). DATA SOURCE: MDS and Mortality Register. VARIABLES: gender, age, place of death, tumour location, clinical activity data and costs in the last three months of life. We performed a descriptive analysis of clinical activity and costs, and lineal multivariate regressions to obtain the adjusted mean costs by gender, age and place of death. RESULTS: 9,333 deaths from malignancy were identified in 2010 and 2011. 65.4% were men, 61.5% aged 70 or over, mean age 72.9 years, 71.1% died in hospital. People who died in the hospital had an average cost of about double that of the people who died at home (€14,794 and €7,491, respectively; p <0.001) and 31.3% higher than in the nursing home (€11,269; p <0.001). CONCLUSIONS: Greater interventions at the end of life at the community level are necessary, strengthening the care capacity of primary health care, both from training and support from expert teams in order to change the current care profile to a more outpatient care that allows a lower consumption of resources and greater care at home.

[Contextual indicators to assess social determinants of health and the Spanish economic recession]. / Indicadores contextuales para evaluar los determinantes sociales de la salud y la crisis económica española.

OBJECTIVE: To provide indicators to assess the impact on health, its social determinants and health inequalities from a social context and the recent economic recession in Spain and its autonomous regions. METHODS: Based on the Spanish conceptual framework for determinants of social inequalities in health, we identified indicators sequentially from key documents, Web of Science, and organisations with official statistics. The information collected resulted in a large directory of indicators which was reviewed by an expert panel. We then selected a set of these indicators according to geographical (availability of data according to autonomous regions) and temporal (from at least 2006 to 2012) criteria. RESULTS: We identified 203 contextual indicators related to social determinants of health and selected 96 (47%) based on the above criteria; 16% of the identified indicators did not satisfy the geographical criteria and 35% did not satisfy the temporal criteria. At least 80% of the indicators related to dependence and healthcare services were excluded. The final selection of indicators covered all areas for social determinants of health, and 62% of these were not available on the Internet. Around 40% of the indicators were extracted from sources related to the Spanish Statistics Institute. CONCLUSIONS: We have provided an extensive directory of contextual indicators on social determinants of health and a database to facilitate assessment of the impact of the economic recession on health and health inequalities in Spain and its autonomous regions.
