Socioeconomic disparities in diet and physical activity in children: evidence from well-child visit electronic health records in the Canary Islands, Spain.

BACKGROUND: Diet and physical activity (PA) in childhood are heavily influenced by the living environment. While diet quality follows a socioeconomic pattern, limited evidence is available in relation to PA in children. We assessed the effect of socioeconomic status at the individual (SES) and neighbourhood (NSES) levels on diet and PA among children from the general population of the Canary Islands, Spain. METHODS: In this cross-sectional study, patients aged 6-14 years from the Canary Health Service in 2018 were included (n=89 953). Diet and PA surveys from the electronic health records of the well-child visit programme were used. A healthy habits (HH) score was defined to assess the level of adherence to the dietary and leisure time PA guidelines. We modelled the association between the HH score, SES and NSES using a stepwise multilevel linear regression analysis, differentiating between specific and general contextual observational effects. RESULTS: A strong positive association between SES and the HH score was found, as children living in more affluent families were more likely to follow a healthy diet and being physically active. Differences in the HH score between geographical areas were of minor relevance (variance partition coefficient=1.8%) and the general contextual effects were not substantially mediated by NSES (proportional change in variance=3.5%). However, the HH score was significantly lower in children from areas with a higher percentage of annual incomes below the €18 000 threshold. CONCLUSION: HH followed a socioeconomic gradient at the individual and the neighbourhood level. In the study population, the geographical component of the inequalities found were low.

Unravelling risk selection in Spanish general government employee mutual funds: evidence from cancer hospitalizations in the public health network.

Government employees in Spain are covered by public Mutual Funds that purchase a uniform basket of benefits, equal to the ones served to the general population, from private companies. Companies apply as private bidders for a fixed per capita premium hardly adjusted by age. Our hypothesis is that this premium does not cover risks, and companies have incentives for risk selection, which are more visible in high-cost patients. We focus on a particularly costly disease, cancer, whose prevalence is similar among government employees and the general population. We compare hospitalisations in the public hospitals of the government employees that have chosen public provision and the general population. We analysed a database of hospital discharges in the Valencian Community from 2010 to 2015 (3 million episodes). Using exact matching and logistic models, we find significant risk selection; thus, in hospitalised government employees, the likelihood for a solid metastatic carcinoma and non-metastatic cancer to appear in the registry is 31% higher than in the general population. Lymphoma shows the highest odds ratio of 2.64. We found quantitatively important effects. This research provides indirect evidence of risk selection within Spanish Mutual Funds for government employees, prompting action to reduce incentives for such a practice. More research is needed to figure out if what we have observed with cancer patients occurs in other conditions.

How has the strict lockdown during the SARS-COV-2 outbreak changed the diet of Spaniards?

Purpose: We investigate the impact of a specific macroeconomic shock that occurred as a response to the SARS-COV-2 outbreak, namely the strict lockdown imposed in Spain on the March 14, 2020. Methods: We use fortnightly purchase data relating to over 50,000 households from a supermarket chain in Catalonia from March to June in 2019 and 2020. Using a panel data approach, we analyse the impact of the lockdown on the caloric content, sugar composition, and alcohol content in beverages and food purchases bought before and after lockdown. We corrected our results to take into account the likelihood of stockpiling. Results: The lockdown is related to an increase in unhealthy beverage and food purchases. We find heterogeneous effects across groups of the sample based on cardholder characteristics. Families with children or babies and those in the upper two income quintiles had the unhealthiest changes. As the lockdown went through phases of relaxation, households made better food decisions but maintained unhealthy beverage choices. Conclusions: The very restrictive lockdown negatively impacted the characteristics of food and beverage purchases made by Spaniards. However, we are unsure whether there was substitution to restaurant and bar visits. Additional work to find out whether there were permanent changes in purchasing behaviour after lockdown ended is needed in the future.

The Economic Impact of the SARS-COV-2 (COVID-19) Pandemic in Spain.

BACKGROUND: The COVID-19 pandemic has hit both the Spanish economy and the population's health hard. The result is an unprecedented economic and social crisis due to uncertainty about the remedy and the socioeconomic effects on people's lives. METHODS: We performed a retrospective analysis of the macroeconomic impact of the COVID-19 pandemic in 2020 using key indicators of the Spanish economy for the 17 Autonomous Communities (ACs) of the country. National statistics were examined in the search for impacts or anomalies occurring since the beginning of the pandemic. To estimate the strength of the impact on each of the indicators analyzed, we used Bayesian structural time series. We also calculated the correlation between the rate of GDP decline during 2020 and the cumulative incidence of COVID-19 cases per 100,000 inhabitants in the ACs. RESULTS: In 2020, the cumulative impact on the gross domestic product was of -11.41% (95% credible interval: -13.46; -9.29). The indicator for business turnover changed by -9.37% (-12.71; -6.07). The Spanish employment market was strongly affected; our estimates showed a cumulative increase of 11.9% (4.27; 19.45) in the rate of unemployment during 2020. The worst indicators were recorded in the ACs most economically dependent on the services sector. There was no statistical association between the incidence of COVID-19 in 2020 and the fall in GDP in the ACs. CONCLUSIONS: Our estimates portray a dramatic situation in Spain, where the COVID-19 crisis has had more serious economic and health consequences than in other European countries. The productive system in Spain is too dependent on sectors vulnerable to the pandemic, and it is necessary to design and implement profound changes through the European Next Generation program.

How do consumers respond to "sin taxes"? New evidence from a tax on sugary drinks.

It is unclear what the effects of taxes on sugar sweetened beverages (SSBs) are on consumer behaviour and which consumers may be affected the most. We evaluate the effect of the SSB tax introduced in Catalonia (but not in the rest of Spain) in May 2017 using loyalty card data of monthly purchases by 884,843 households from May 2016 to April 2018. Using a Difference-in-Differences approach, we study the SSB tax effect on the purchased quantity of beverages and sugar. Our results suggest a reduction in purchases of taxed beverages and a small increase in purchases of untaxed beverages. Households have substituted taxed beverages with their lower sugar (untaxed) counterparts. This has led to a 2.2% overall reduction in sugar purchases from beverages. Our study implies that although sin taxes moderately change consumer behaviour, a combination of different policies would be required to tackle obesity.

When Industrial Policies Conflict With Population Health: Potential Impact of Removing Food Subsidies on Obesity Rates.

OBJECTIVES: To model the potential impact on obesity of removing butter, cheese, and sugar subsidies in the Canary Islands. METHODS: A simulation model was applied based on a local data set of subsidies and retail prices (2007-2016), data on own-price elasticity estimates, and representative nutritional and health surveys. We estimated marginal obesity prevalence and population attributable fraction to assess the potential impact of the butter, cheese, and sugar subsidies intervention. RESULTS: The intervention was predicted to avoid 10 363 obese adults over the study period, because of the reduction of the obesity prevalence by -0.7 percentage points. Overall, the predicted effect was largest in elderly and male groups, although females with a low socioeconomic status experienced the greatest decrease in the prevalence. The population attributable fraction predicted that 4.0% of population with obesity were attributable to the existence of these subsidies. CONCLUSIONS: This analysis provides policy makers with the predicted impact on obesity of the butter, cheese, and sugar subsidies disposal, enabling them to incorporate this health impact into decision making across policy areas in the economic and health field. This study aims to model the potential impact on obesity of removing industrial subsidies for butter, cheese and sugar in the Canary Islands.

Preferences of Patients With HR+ and HER2- Breast Cancer Regarding Hormonal and Targeted Therapies in the First Line of Their Metastatic Stage: A Discrete Choice Experiment.

OBJECTIVE: Some hormonal and targeted treatment options are available in the first line of metastatic HR+ & HER2- breast cancer. This study aimed to quantify the preferences of Iranian breast cancer patients regarding the levels of attributes of hypothetical treatment options. METHODS: The discrete choice experiment included 16 orthogonally designed scenarios. A novel method (named "the World Cup") was used to offer the scenarios to the respondents. Each choice task had 2 hypothetical treatments. A conditional logit regression model was used to obtain preference estimates, based on an expected utility model without interactions between attributes. RESULTS: A total of 78 patients with breast cancer participated in the survey. The effectiveness was the main concern of the patient, which was followed by monthly cost. Participant patients significantly preferred to avoid adverse events; preference dummy-coded estimates were reported. CONCLUSION: Followed by the effectiveness and cost, the risk of neutropenia, stomatitis, and arthralgia was least prioritized by the respondents. The estimation for the levels of the attribute "administration mode" is not significant (P = .690). Patients with breast cancer were willing to pay significant amounts to gain the benefit of the treatments and showed a significant willingness to accept to avoid the adverse events of the treatments.

Income and wealth as determinants of voluntary private health insurance: empirical evidence in Spain, 2008-2014.

BACKGROUND: Few studies have quantitatively estimated the income elasticity of demand of voluntary private health insurance (VPHI) in countries with a universal National Health Service. Most studies to date have uses cross-sectional data. METHODS: In this paper we used a longitudinal database from the Bank of Spain to analyse the financial behaviour of approximately six thousand families per wave. We used three waves (2008, 2011 and 2014). We estimated income and wealth semi-elasticities of VPHI in Spain considering personal and family characteristics (age, sex, level of health, education, composition of the household), i.e. changes in the probability of buying VPHI as result of 1% change in income or wealth. We estimated cross-sectional models for each wave and longitudinal models for families remaining for at least two waves, taking account of possible selection bias due to attrition. RESULTS: Cross-sectional models suggest that the income effect on the probability of buying a VPHI increased from 2008 to 2014. The positive impact was observed for, wealth. In 2008 a 1% increase in income is associated with an increase in the probability of having VPHI of 0.064 [95%-CI: 0.023; 0.104] - on the probability scale (0.1) - whereas in 2014, this effect is of 0.116 [95%-CI, 0.094; 0.139]. In 2011 and 2014 the wealth effect is not significant at 5%. The estimation of the longitudinal model leads to different results where both, income and wealth are associated with non- significant results. CONCLUSION: Our three main conclusions are: 1) Cross-sectional estimates of semi-elasticities of VPHI might be biased upwards; 2) Wealth is alongside income are economic determinants, of the decision to buy VPHI in high-income countries; 3) The effects of income and wealth on the probability of buying VHPI are neither linear nor log-linear. There are no significant differences among 60% of the most disadvantaged families, while the families of the two upper wealth quintiles show clearly differentiated behaviour with a higher probability of insurance.

Dying at home for terminal cancer patients: differences by level of education and municipality of residence in Spain / Morir en casa pacientes terminales con cáncer: diferencias por nivel de educación y municipio de residencia en España

Objective: To measure and assess differences by educational level in the place of death for cancer patients, and to determine whether patterns of geographical disparities are associated with access to palliative care services in the municipality of residence. Method: We analysed the death certificates of adults (older than 24) who died of cancer (ICD-10 C00 to C97) in Spain during 2015, either at home, in hospital or in a long-term care centre. Of the 105,758 individuals included in the study population, 75.2% lived in one of the 746 identifiable municipalities (more than 10,000 inhabitants). This individual database was combined with three economic databases at municipal level and with a directory of palliative care resources published by the Sociedad Española de Cuidados Paliativos. Multilevel models were estimated to predict the place of death according to individual characteristics. Generalised least squares regression models were then applied to the municipal effects estimated in the first stage. Results: The probability of dying in long-term care centre decreases as levels of education increase; the probability of dying at home, rather than in hospital, is higher for patients with higher education. Dying in hospital is an urban phenomenon. There are large differences between Spanish regions. Access to palliative services is only of marginal significance in accounting for the systematic differences observed between municipalities. Conclusions: Developing specific plans for palliative care, with an active role being played by primary care teams, may help improve end-of-life care in Spain

Objetivo: Medir y evaluar las diferencias por nivel educativo respecto al lugar de muerte de pacientes con cáncer en España, y determinar si los patrones de desigualdad geográfica están asociados con el acceso a servicios de cuidados paliativos en el municipio de residencia. Método: Analizamos los certificados de defunción de mayores de 24 años que murieron de cáncer (CIE-10 C00-C97) en España durante 2015, en el hogar, en el hospital o en una residencia sociosanitaria. Sobre una población total de 105.758 personas, el 75,2% vivía en uno de los 746 municipios identificables (más de 10.000 habitantes). La base de datos individual se combina con datos económicos de ámbito municipal y con el directorio de recursos de cuidados paliativos publicado por la Sociedad Española de Cuidados Paliativos. Se estiman modelos multinivel para predecir el lugar de la muerte de acuerdo con las características individuales. A continuación, se estiman modelos de regresión por mínimos cuadrados generalizados sobre los efectos municipales estimados en el modelo anterior. Resultados: La probabilidad de morir en casa, frente al hospital, es mayor en los pacientes con educación superior. Morir en el hospital resulta un fenómeno urbano. Hay grandes diferencias entre regiones. El acceso a los servicios paliativos solo tiene una importancia marginal en la explicación de las diferencias entre municipios. Conclusión: El desarrollo de planes específicos para cuidados paliativos, con un papel más activo de los equipos de atención primaria, puede ayudar a mejorar la atención sanitaria al final de la vida en España

Impact of the Spanish smoke-free laws on cigarette sales, 2000-2015: partial bans on smoking in public places failed and only a total tobacco ban worked.

In January 2006, the Spanish government enacted a tobacco control law that banned smoking in bars and restaurants, with exceptions depending on the floor space of the premises. In January 2011, further legislation in this area was adopted, removing these exceptions. We analyse the effect produced on cigarette sales by these two bans. We approach this problem using an interrupted time series analysis while accounting for the potential effects of autocorrelation and seasonality. The data source used was the official data on legal sales of tobacco in Spain, from January 2000 to December 2015 (excluding the Canary Islands and the autonomous cities of Ceuta and Melilla). As confounder variables, we use the log-transformed average prices for manufactured and hand-rolled cigarettes (or the average minimum excise tax as a proxy), and log-transformed real-household disposable income. The implementation of a total smoke-free ban in Spain was associated with an immediate reduction in cigarette sales between 9% to 11%. In contrast, in the period immediately following the partial ban, no such reduction was detected, beyond the trend already present. Our results indicate that, in Spain, partial bans on smoking in public places failed, and that only a total tobacco ban worked.

Review of medical professional organizations in developed countries: problems of decentralized membership registers.

This article provides a critical review of international experiences regarding the professional organization of physicians and the registration of doctors in developed countries. The problems faced by professional medical organizations in the EU-15 countries, Japan, the United States and Canada, are examined. Medical professional groups differ in several dimensions, including obligatory registration versus voluntary membership or types of registration (centralized, indirect, or delegated). The centralization-decentralization axis is a key aspect for the analysis. While decentralized systems are better able to adapt to the idiosyncrasy of a particular region, decentralization is identified as a source of potential problems in the organization of medical doctors. Some of these problems (discrepancies in positions on health matters, problems with the reliability of statistical information on medical demography at national level, deficient mechanisms for the control of doctors who have lost their licenses) might have consequences for the quality of the health care system.

Effect of Tourism Pressure on the Mediterranean Diet Pattern.

Despite proposed conceptual frameworks of eating behaviors, little is known about environmental factors contributing to changes in food habits. Few studies have reported the external influence of tourism on the inhabitants' eating patterns. The present study aimed to investigate whether tourism pressure affects Canary Islands inhabitants' adherence to the Mediterranean diet pattern. Data were obtained from a health and lifestyle population-based survey conducted in 2009 and 2015. From the reported intake frequency, a Mediterranean diet score was defined (0 to 11 points). Tourist overnight stays, which were stratified by nationality and area of destination, were used as a proxy variable to measure tourism pressure. A multilevel linear regression analysis by restricted maximum likelihood estimation was performed to examine the relationship between tourism pressure and the Mediterranean diet score. A significant negative association between the Mediterranean diet score and British tourism pressure was observed (ß = -0.0064, p = 0.010), whereas German tourism pressure increased inhabitants' adherence (ß = 0.0092, p = 0.042). The socioeconomic level of tourists seems to play a role in differences in the tourism pressure effect by nationality. Further investigation of other highly touristic destinations is needed to confirm these findings that could contribute to a shift in tourism and public health nutrition policies.

Pinocchio testing in the forensic analysis of waiting lists: using public waiting list data from Finland and Spain for testing Newcomb-Benford's Law.

OBJECTIVE: Newcomb-Benford's Law (NBL) proposes a regular distribution for first digits, second digits and digit combinations applicable to many different naturally occurring sources of data. Testing deviations from NBL is used in many datasets as a screening tool for identifying data trustworthiness problems. This study aims to compare public available waiting lists (WL) data from Finland and Spain for testing NBL as an instrument to flag up potential manipulation in WLs. DESIGN: Analysis of the frequency of Finnish and Spanish WLs first digits to determine if their distribution is similar to the pattern documented by NBL. Deviations from the expected first digit frequency were analysed using Pearson's χ2, mean absolute deviation and Kuiper tests. SETTING/PARTICIPANTS: Publicly available WL data from Finland and Spain, two countries with universal health insurance and National Health Systems but characterised by different levels of transparency and good governance standards. MAIN OUTCOME MEASURES: Adjustment of the observed distribution of the numbers reported in Finnish and Spanish WL data to the expected distribution according to NBL. RESULTS: WL data reported by the Finnish health system fits first digit NBL according to all statistical tests used (p=0.6519 in χ2 test). For Spanish data, this hypothesis was rejected in all tests (p<0.0001 in χ2 test). CONCLUSIONS: Testing deviations from NBL distribution can be a useful tool to identify problems with WL data trustworthiness and signalling the need for further testing.

Breakfast choice: An experiment combining a nutritional training workshop targeting adolescents and the promotion of unhealthy products.

A randomised control trial was conducted to determine changes in the food and drink choices of adolescents following their participation in a 50-min nutrition workshop. The experiment was conducted at 104 schools in Barcelona (126 classes, 3,291 adolescents). Schools were randomly selected and stratified by district and by public or private status. The students were given three types of vouchers with different options regarding the type of food for which the vouchers could be exchanged (standard for healthy food and drink, two for one for unhealthy food, and two for one for unhealthy drink). Difference-in-differences linear models that control for individual, family, school or neighbourhood characteristics, and the influence of peers were applied. The probability of students' choosing unhealthy food and drink fell by 7.1% and 4.4%, respectively, following participation in the nutrition workshop. The promotion of unhealthy beverages counteracted the positive impact of the workshop on beverage choice.

Estimating direct effects of parental occupation on Spaniards' health by birth cohort.

BACKGROUND: Social health inequalities in adult population are partly due to socioeconomic circumstances in childhood. A better understanding of how those circumstances affect health during adulthood may improve the opportunities for reducing health disparities. The objective of this study is to investigate the effect of parental socioeconomic status, which is proxied by occupation, on adult Spaniards' health by birth cohort. The analysis will allow checking not only the direct impact of parental occupation on their offspring's health, but also whether inherited inequality has been reduced over time. METHODS: We use data from the Bank of Spain's Survey of Household Finances on Spanish households from 2002 to 2008. Sequential models were used to estimate the influence of the father's and mother's occupation on their offspring's health, trying to disentangle direct from indirect effects. With a sample of 26,832 persons we consider effects for four different cohorts by birth periods ranging from 1916 to 1981. RESULTS: The results show that parental occupation has a significant direct impact on individuals' health (p < 0.01). The effect of father's occupation exceeds that of mother's. For those born before 1936, the probability of reporting a good health status ranges from 0.31 (95% confidence interval (CI) 0.14-0.48), when fathers were classified as unskilled elementary workers, to 0.98 (95% CI 0.98-0.99) when they were managers or mid-level professionals. For those born during the period 1959-1975, those probabilities are 0.49 (95% CI 0.39-0.59) and 0.97 (95% CI 0.96-0.98), respectively. Therefore, health inequalities linked to parental socioeconomic status have been noticeably reduced, although discrimination against unskilled workers persists over time. CONCLUSIONS: Great progress has been made in the health area during the twentieth century, so that the impact of parental socioeconomic status on individuals' health has been significantly tempered for those at the bottom of the social scale. However, more efforts focused on the improvement of living conditions for most socioeconomically disadvantaged are needed in order to further reduce social inequalities in health.

Allocation of Residency Training Positions in Spain: Contextual Effects on Specialty Preferences.

In Spain's 'MIR' system, medical school graduates are ranked by their performance on a national exam and then sequentially choose from the available residency training positions. We took advantage of a unique survey of participants in the 2012 annual MIR cycle to analyze preferences under two different choice scenarios: the residency program actually chosen by each participant when it came her turn (the 'real') and the program that she would have chosen if all residency training programs had been available (the 'counterfactual'). Utilizing conditional logit models with random coefficients, we found significant differences in medical graduates' preferences between the two scenarios, particularly with respect to three specialty attributes: work hours/lifestyle, prestige among colleagues, and annual remuneration. In the counterfactual world, these attributes were valued preferentially by those nearer to the top, while in the real world, they were valued preferentially by graduates nearer to the bottom of the national ranking. Medical graduates' specialty preferences, which we conclude, are not intrinsically stable but depend critically on the 'rules of the game'. The MIR assignment system, by restricting choice, effectively creates an externality in which those at the bottom, who have fewer choices, want what those at the top already have.

Economic Crisis, Austerity Policies, Health and Fairness: Lessons Learned in Spain.

This paper reviews economic and medical research publications to determine the extent to which the measures applied in Spain to control public health spending following the economic and financial crisis that began in 2008 have affected healthcare utilization, health and fairness within the public healthcare system. The majority of the studies examined focus on the most controversial cutbacks that came into force in mid-2012. The conclusions drawn, in general, are inconclusive. The consequences of this new policy of healthcare austerity are apparent in terms of access to the system, but no systematic effects on the health of the general population are reported. Studies based on indicators of premature mortality, avoidable mortality or self-perceived health have not found clear negative effects of the crisis on public health. The increased demands for co-payment provoked a short-term cutback in the consumption of medicines, but this effect faded after 12-18 months. No deterioration in the health of immigrants after the onset of the crisis was unambiguously detected. The impact of the recession on the general population in terms of diseases associated with mental health is well documented; however, the high levels of unemployment are identified as direct causes. Therefore, social policies rather than measures affecting the healthcare system would be primarily responsible. In addition, some health problems have a clear social dimension, which seems to have become more acute during the crisis, affecting in particular the most vulnerable population groups and the most disadvantaged social classes, thus widening the inequality gap.
