Effect of COVID-19 prevention as part of an urban renewal programme.

OBJECTIVES: To address existing inequalities, the Barcelona City Council launched a Neighbourhood Plan in 2016-2020. During the first wave of the COVID-19 pandemic, the Neighbourhood Plan interventions were intensified. This study aimed to assess the effect of the plan on the incidence of COVID-19 during the first wave of the pandemic in Barcelona. STUDY DESIGN: We used a quasi-experimental design with 16 intervention neighbourhoods and 17 neighbourhoods in the comparison group with similar socioeconomic characteristics. METHODS: We calculated the cumulative incidence rate (CIR) of COVID-19 per 100,000 inhabitants by sex, age groups, and neighbourhood of residence. Poisson regression models were fitted to estimate the crude relative risk and relative risk adjusted by socioeconomic status (cRR and aRR) and their 95% confidence intervals (CIs). RESULTS: The CIR of COVID-19 was lower in the intervention neighbourhoods (CIR: 841 per 100,000 inhabitants) than in the comparison group (CIR: 973 per 100,000 inhabitants). On multivariate analysis, the aRR was 0.77 (CI: 0.70-0.83) for men and 0.89 (CI: 0.83-0.96) for women. Among men older than 75 years (aRR = 0.73; CI: 0.62-0.86), statistically significant differences were found in the intervention neighbourhoods compared to the comparison group. This pattern was not observed in women older than 75 years (aRR = 1.13; CI: 0.99-1.30). CONCLUSION: This research finds positive short-term effect in the intervention neighbourhoods. We conclude that the COVID-19 control and prevention interventions are likely to explain the better performance in the neighbourhoods included in the Neighbourhood Plan.

Bibliometric analysis in paediatric dental journals listed in journal citation reports. Current trends.

AIM: The aim of this study was to analyse articles published in paediatric dental journals included in Journal Citation Reports (JCR), to determine current trends in paediatric publishing. METHODS: Articles included in paediatric dentistry journals in 2020 JCR were selected, published during the period 2008-2020. After applying inclusion criteria, author-based parameters (article title, first author's name, institution, sex and number of authors, number of affiliations, first/last author's origin and geographic origin), and article-based parameters (article type, main topic, research design) were registered for each article. CONCLUSION: International Journal of Paediatric Dentistry, Journal of Clinical Pediatric Dentistry, European Journal of Paediatric Dentistry and Pediatric Dentistry were the four main journals in terms of production volume, USA being the most productive country. The most recurrent topic was dental surgery, and the most common design was observational studies. Study design, geographic origin of the articles, article type and main subject of the article might predict citation.

Diabetes mellitus mortality in Spanish cities: Trends and geographical inequalities.

AIM: To analyze the geographical pattern of diabetes mellitus (DM) mortality and its association with socioeconomic factors in 26 Spanish cities. METHODS: We conducted an ecological study of DM mortality trends with two cross-sectional cuts (1996-2001; 2002-2007) using census tract (CT) as the unit of analysis. Smoothed standardized mortality rates (sSMR) were calculated using Bayesian models, and a socioeconomic deprivation score was calculated for each CT. RESULTS: In total, 27,757 deaths by DM were recorded, with higher mortality rates observed in men and in the period 1996-2001. For men, a significant association between CT deprivation score and DM mortality was observed in 6 cities in the first study period and in 7 cities in the second period. The highest relative risk was observed in Pamplona (RR, 5.13; 95% credible interval (95%CI), 1.32-15.16). For women, a significant association between CT deprivation score and DM mortality was observed in 13 cities in the first period and 8 in the second. The strongest association was observed in San Sebastián (RR, 3.44; 95%CI, 1.25-7.36). DM mortality remained stable in the majority of cities, although a marked decrease was observed in some cities, including Madrid (RR, 0.67 and 0.64 for men and women, respectively). CONCLUSIONS: Our findings demonstrate clear inequalities in DM mortality in Spain. These inequalities remained constant over time are were more marked in women. Detection of high-risk areas is crucial for the implementation of specific interventions.

Process-generated nanoparticles from ceramic tile sintering: Emissions, exposure and environmental release.

The ceramic industry is an industrial sector in need of significant process changes, which may benefit from innovative technologies such as laser sintering of ceramic tiles. Such innovations result in a considerable research gap within exposure assessment studies for process-generated ultrafine and nanoparticles. This study addresses this issue aiming to characterise particle formation, release mechanisms and their impact on personal exposure during a tile sintering activity in an industrial-scale pilot plant, as a follow-up of a previous study in a laboratory-scale plant. In addition, possible particle transformations in the exhaust system, the potential for particle release to the outdoor environment, and the effectiveness of the filtration system were also assessed. For this purpose, a tiered measurement strategy was conducted. The main findings evidence that nanoparticle emission patterns were strongly linked to temperature and tile chemical composition, and mainly independent of the laser treatment. Also, new particle formation (from gaseous precursors) events were detected, with nanoparticles <30nm in diameter being formed during the thermal treatment. In addition, ultrafine and nano-sized airborne particles were generated and emitted into workplace air during sintering process on a statistically significant level. These results evidence the risk of occupational exposure to ultrafine and nanoparticles during tile sintering activity since workers would be exposed to concentrations above the nano reference value (NRV; 4×10(4)cm(-3)), with 8-hour time weighted average concentrations in the range of 1.4×10(5)cm(-3) and 5.3×10(5)cm(-3). A potential risk for nanoparticle and ultrafine particle release to the environment was also identified, despite the fact that the efficiency of the filtration system was successfully tested and evidenced a >87% efficiency in particle number concentrations removal.

Evolution of socio-economic inequalities in mortality in small geographical areas of the two largest cities in Spain (Barcelona and Madrid), 1996-2007.

OBJECTIVES: To describe the evolution of socio-economic inequalities in mortality in small areas of two Spanish cities (Barcelona and Madrid) from 1996 to 2001 and from 2002 to 2007. STUDY DESIGN: A small-area ecological study of trends was performed, in which the units of analysis were census tracts. METHODS: The association between mortality and socio-economic deprivation was assessed through Poisson regression analysis. Models were stratified by sex, age group and period of study. The trend in inequalities in mortality was assessed by introducing an interaction term between deprivation and the period of study. RESULTS: Mortality in the most-deprived areas was significantly higher than mortality in the less-deprived areas in both periods and most age groups. However, inequalities seemed to diminish in young people and elderly women, especially in Barcelona. CONCLUSIONS: There is a need to monitor inequalities in mortality in the near future because the current financial crisis could change this situation.

Social determinants of self-perceived discrimination in Spain.

OBJECTIVES: To analyse the association between self-perceived discrimination and social determinants (social class, gender, country of origin) in Spain, and further to describe contextual factors which contribute to self-perceived discrimination. METHODS: Cross-sectional design using data from the Spanish National Health Survey (2006). The dependent variable was self-perceived discrimination, and independent and stratifying variables were sociodemographic characteristics (e.g. sex, social class, country of origin, educational level). Logistic regression was used. RESULTS: The prevalence of self-perceived discrimination was 4.2% for men and 6.3% for women. The likelihood of self-perceived discrimination was higher in people who originated from low-income countries: men, odds ratio (OR) 5.59 [95% confidence interval (CI) 4.55-6.87]; women, OR 4.06 (95% CI 3.42-4.83). Women were more likely to report self-perceived discrimination by their partner at home than men [OR 8.35 (95% CI 4.70-14.84)]. The likelihood of self-perceived discrimination when seeking work was higher among people who originated from low-income countries than their Spanish counterparts: men, OR 13.65 (95% CI 9.62-19.35); women, OR 10.64 (95% CI 8.31-13.62). In comparison with Spaniards, male white-collar workers who originated from low-income countries [OR 11.93 (95% CI 8.26-17.23)] and female blue-collar workers who originated from low-income countries (OR 1.6 (95% CI 1.08-2.39)] reported higher levels of self-perceived discrimination. CONCLUSIONS: Self-perceived discrimination is distributed unevenly in Spain and interacts with social inequalities. This particularly affects women and immigrants.

Socioeconomic position and type 2 diabetes mellitus in Europe 1999-2009: a panorama of inequalities.

The aim of the present review is to synthesis findings from studies on the relationship between socioeconomic position (SEP) and incidence, prevalence and mortality of type 2 diabetes mellitus (T2DM) in Europe between the years 1999 and 2009. A systematic search was carried out in the National Library of Medicine's PubMed database. The search was limited to articles published between January 1999 and December 2009, in English or Spanish. Additional requirements for inclusion were: (i) presentation of empirical results directly related with SEP and the prevalence, incidence or mortality of diabetes, (ii) dealing with T2DM, (iii) carried out in Europe, and (iv) mainly focused only on diabetes. Of the 19 articles found, twelve studied the relationship between SEP and the prevalence of T2DM, two dealt with diabetes incidence, three with mortality and two studied both inequalities in mortality and prevalence. People with more deprived SEP have greater incidence, more prevalence and higher mortality due to T2DM, although the magnitude and significance of the associations varied from one study to another. Part of these inequalities is explained by SEP differences in the prevalence of the established T2DM risk factors. SEP inequalities in T2DM tended to be greater in women than in men. There is consistent evidence that SEP inequalities in T2DM incidence, prevalence and mortality are present in Europe, especially among women. Improving accessibility of physical activity in terms of both price and availability, access to healthy food, and access to health services, will be key to achieving a reduction of SEP related diabetes inequalities in Europe.

Social inequalities in health among adolescents in a large southern European city.

BACKGROUND: Numerous health problems are initiated in childhood and adolescence. For example, obesity, which has increased significantly in recent years, often begins in early life. The objective of this study is to describe social inequalities in obesity and other health problems among adolescents, by sex. METHODS: Data were from a cross-sectional study conducted in a representative sample of 903 adolescents aged 12-16 years old, from secondary schools in Barcelona, Spain. Associations between socioeconomic indicators and health outcomes (perceived health status, and overweight and obesity) were examined through generalised estimating equation models. All analyses were stratified by sex. RESULTS: Boys were more likely to report very good perceived health status than girls (64.1% and 46.3%, respectively). Some of the less privileged socioeconomic position indicators were associated with the presence of overweight and obesity (prevalence ratio 2.41 for low family affluence scale in girls), and with a lower probability of reporting very good perceived health status among boys (prevalence ratio 0.75 for primary level of paternal education). CONCLUSIONS: This study suggests that there are social inequalities in perceived health status, overweight and obesity, measured by different socioeconomic indicators among the adolescent population of Barcelona, and that these inequalities were distributed differently among boys and girls. Gender differences in the impact of socioeconomic variables in health need to be considered in epidemiological and intervention studies.

Substance use among road traffic casualties admitted to emergency departments.

OBJECTIVE: To describe the prevalence of recent psychoactive substance use and associated factors among road traffic casualties admitted to emergency departments. METHODS: A cross-sectional study was carried out, including adults injured in road traffic crashes admitted to the emergency department (ED) of eight hospitals in Catalonia (Spain), during three cross-sections, each of 4 days duration (2005-2006). Information sources were an interview, an oral fluid specimen and the patient's clinical record. Dependent variables were presence of alcohol, cannabis, cocaine, ecstasy, opiates or benzodiazepines. Independent variables were socioeconomic characteristics and circumstances of the injuries and admission. Prevalence and exact 95% confidence intervals were estimated for men and women. Bivariate analyses and multivariate binomial regression modelling were carried out to study factors associated with substance use in male drivers and pedestrians. RESULTS: The prevalence of substance use was higher in men (n = 226) than in women (n = 161) for any substance (34.4% and 16.2%), any illegal substance (19.3% and 7.6%), alcohol (18.5% and 9.2%) and cannabis (17.0% and 3.8%), respectively. In male drivers and pedestrians, alcohol use was associated with being in the 25-30-year age group, being injured at night and the weekend, and arriving at the ED by ambulance; cannabis use was only associated with being in the 18-30-year age group. CONCLUSIONS: A high prevalence of recent psychoactive substance use, especially alcohol, cannabis and cocaine, was observed in all age groups. The results indicate the need to screen for substance use and to give simple advice to casualties at EDs.

Socioeconomic inequalities in lung cancer mortality in 16 European populations.

OBJECTIVES: This paper aims to describe socioeconomic inequalities in lung cancer mortality in Europe and to get further insight into socioeconomic inequalities in lung cancer mortality in different European populations by relating these to socioeconomic inequalities in overall mortality and smoking within the same or reference populations. Particular attention is paid to inequalities in Eastern European and Baltic countries. METHODS: Data were obtained from mortality registers, population censuses and health interview surveys in 16 European populations. Educational inequalities in lung cancer and total mortality were assessed by direct standardization and calculation of two indices of inequality: the Relative Index of Inequality (RII) and the Slope Index of Inequality (SII). SIIs were used to calculate the contribution of inequalities in lung cancer mortality to inequalities in total mortality. Indices of inequality in lung cancer mortality in the age group 40-59 years were compared with indices of inequalities in smoking taking into account a time lag of 20 years. RESULTS: The pattern of inequalities in Eastern European and Baltic countries is more or less similar as the one observed in the Northern countries. Among men educational inequalities are largest in the Eastern European and Baltic countries. Among women they are largest in Northern European countries. Whereas among Southern European women lung cancer mortality rates are still higher among the high educated, we observe a negative association between smoking and education among young female adults. The contribution of lung cancer mortality inequalities to total mortality inequalities is in most male populations more than 10%. Important smoking inequalities are observed among young adults in all populations. In Sweden, Hungary and the Czech Republic smoking inequalities among young adult women are larger than lung cancer mortality inequalities among women aged 20 years older. CONCLUSIONS: Important socioeconomic inequalities exist in lung cancer mortality in Europe. They are consistent with the geographical spread of the smoking epidemic. In the next decades socioeconomic inequalities in lung cancer mortality are likely to persist and even increase among women. In Southern European countries we may expect a reversal from a positive to a negative association between socioeconomic status and lung cancer mortality. Continuous efforts are necessary to tackle socioeconomic inequalities in lung cancer mortality in all European countries.

Inequalities in caesarean section: influence of the type of maternity care and social class in an area with a national health system.

OBJECTIVE: To analyse the impact of social class inequalities and type of maternity unit in the use of caesarean sections (CSs) among residents in an urban area of Southern Europe. DESIGN: This was a cross-sectional study. The study population consisted of 2186 women resident in Barcelona city who gave birth to an infant without any birth defect during 1994-2003. The dependent variable was the type of delivery. Maternal age, social class and type of maternity unit (public or private) were independent variables. Maternal age-adjusted logistic regression models were used. RESULTS: 30% of deliveries ended in CS; 70% of less privileged women delivered in public maternity units and 72% of more privileged women delivered in private centres. A relationship between CS and social class was observed (OR 1.4; 95% CI 1.1 to 1.7), but disappeared when the analysis was done separately for each stratum of type of maternity unit (both ORs 1.0). In contrast, a relationship between CS and type of maternity unit was found (OR 2.3; 95% CI 1.9 to 2.7), which persisted when the analysis was done separately for each stratum of social class. CONCLUSION: Although strongly related to higher social class, the main determinant of the high proportion of CSs was delivering in private maternity units.

Socioeconomic inequalities in diabetes mellitus across Europe at the beginning of the 21st century.

AIMS/HYPOTHESIS: The aim of this study was to determine and quantify socioeconomic position (SEP) inequalities in diabetes mellitus in different areas of Europe, at the turn of the century, for men and women. METHODS: We analysed data from ten representative national health surveys and 13 mortality registers. For national health surveys the dependent variable was the presence of diabetes by self-report and for mortality registers it was death from diabetes. Educational level (SEP), age and sex were independent variables, and age-adjusted prevalence ratios (PRs) and risk ratios (RRs) were calculated. RESULTS: In the overall study population, low SEP was related to a higher prevalence of diabetes, for example men who attained a level of education equivalent to lower secondary school or less had a PR of 1.6 (95% CI 1.4-1.9) compared with those who attained tertiary level education, whereas the corresponding value in women was 2.2 (95% CI 1.9-2.7). Moreover, in all countries, having a disadvantaged SEP is related to a higher rate of mortality from diabetes and a linear relationship is observed. Eastern European countries have higher relative inequalities in mortality by SEP. According to our data, the RR of dying from diabetes for women with low a SEP is 3.4 (95% CI 2.6-4.6), while in men it is 2.0 (95% CI 1.7-2.4). CONCLUSIONS/INTERPRETATION: In Europe, educational attainment and diabetes are inversely related, in terms of both morbidity and mortality rates. This underlines the importance of targeting interventions towards low SEP groups. Access and use of healthcare services by people with diabetes also need to be improved.

Immigration and self-reported health status by social class and gender: the importance of material deprivation, work organisation and household labour.

OBJECTIVE: Spain and Catalonia have experienced several immigration waves over the last century. The goal of this study was to examine the role of social class and its mediating pathways (ie, work organisation, material deprivation at home and household labour) in the association between migration status and health, as well as whether these associations were modified by social class or gender. SETTING: Barcelona city, Spain. DESIGN AND PARTICIPANTS: The study used the Barcelona Health Interview Survey, a cross-sectional survey of 10,000 residents of the city's non-institutionalised population in 2000. The present study was conducted on the working population, aged 16-64 years (2342 men and 1872 women). The dependent variable was self-reported health status. The main independent variable was migration status. Other variables were: social class (measured using Erik Olin Wright's indicators); age; psychosocial and physical working conditions; job insecurity; type of labour contract; number of hours worked per week; material deprivation at home and household labour. Two hierarchical logistic regression models were built by adding different independent variables. RESULTS: Among men, foreigners presented the poorest health status (fully adjusted odds ratios (OR) 2.16; 95% CI 1.14 to 4.10), whereas among women the poorest health status corresponded to those born in other regions of Spain. There was an interaction between migration and social class among women, with women owners, managers, supervisors or professionals born in other regions of Spain reporting a worse health status than the remaining groups (fully adjusted OR 3.60; 95% CI 1.83 to 7.07). CONCLUSION: This study has shown that the pattern of perceived health status among immigrant populations varies according to gender and social class. These results have to be taken into account when developing policies addressed at the immigrant population.

Educational differences in cancer mortality among women and men: a gender pattern that differs across Europe.

We used longitudinal mortality data sets for the 1990s to compare socioeconomic inequalities in total cancer mortality between women and men aged 30-74 in 12 different European populations (Madrid, Basque region, Barcelona, Slovenia, Turin, Switzerland, France, Belgium, Denmark, Norway, Sweden, Finland) and to investigate which cancer sites explain the differences found. We measured socioeconomic status using educational level and computed relative indices of inequality (RII). We observed large variations within Europe for educational differences in total cancer mortality among men and women. Three patterns were observed: Denmark, Norway and Sweden (significant RII around 1.3-1.4 among both men and women); France, Switzerland, Belgium and Finland (significant RII around 1.7-1.8 among men and around 1.2 among women); Spanish populations, Slovenia and Turin (significant RII from 1.29 to 1.88 among men; no differences among women except in the Basque region, where RII is significantly lower than 1). Lung, upper aerodigestive tract and breast cancers explained most of the variations between gender and populations in the magnitude of inequalities in total cancer mortality. Given time trends in cancer mortality, the gap in the magnitude of socioeconomic inequalities in cancer mortality between gender and between European populations will probably decrease in the future.

Trends in socioeconomic mortality inequalities in a southern European urban setting at the turn of the 21st century.

OBJECTIVE: To analyse trends in mortality inequalities by educational level for main causes of death among men and women in Barcelona, Spain, at the turn of the 21st century (1992-2003). METHODS: The population of reference was all Barcelona residents older than 19 years. All deaths between 1992-2003 were included. Educational level was obtained through record linkage between the mortality register and the municipal census of Barcelona city. Variables studied were age, sex, educational level, period of death (four periods of 3 years) and cause of death. Age-standardised mortality rates for each educational level, sex and period were calculated. Poisson regression models were fitted to obtain relative index of inequality (RII) for educational level, adjusted for age for the time-periods. RESULTS: RII for all causes of death was constant (around 1.5), but rate differences were higher in 1995-7 (715.6 per 100,000 in men and 352.8 in women) than in other periods and tended to decrease in men over the periods. Analysis of inequality trends by specific causes of death shows a stable trend for the majority of causes, with higher mortality among those with less education for all causes of death except lung cancer and breast cancer among women having RII below 1. CONCLUSIONS: Relative inequalities in total mortality by sex in Barcelona did not change during the 12 years studied, whereas absolute inequalities tended to decrease in men. Our study fills an important gap in southern Europe and Spanish literature on trends during this period.

Applying an equity lens to tobacco-control policies and their uptake in six Western-European countries.

We identified policies that may be effective in reducing smoking among socioeconomically disadvantaged groups, and examined trends in their level of application between 1985 and 2000 in six western-European countries (Sweden, Finland, the United Kingdom, the Netherlands, Germany, and Spain). We located studies from literature searches in major databases, and acquired policy data from international data banks and questionnaires distributed to tobacco policy organisations/researchers. Advertising bans, smoking bans in workplaces, removing barriers to smoking cessation therapies, and increasing the cost of cigarettes have the potential to reduce socioeconomic inequalities in smoking. Between 1985 and 2000, tobacco control policies in most countries have become more targeted to decrease the smoking behaviour of low-socioeconomic groups. Despite this, many national tobacco-control strategies in western-European countries still fall short of a comprehensive policy approach to addressing smoking inequalities.

AIDS-related knowledge and behaviors in Mozambique.

BACKGROUND: The objective of this study was to describe attitudes and knowledge about AIDS among the population aged 15 to 49 in Chókwè (Mozambique) during the period from March to May 2004, and to study associated factors. METHODS: Cross-sectional study conducted by interviewing 1,055 people aged 15 to 49, of both sexes, residents in Chókwè (68,698 inhabitants). The questionnaires employed are known as the Behavior Surveillance Survey. Dependent variables were: knowledge about transmission routes and preventive methods, use of condoms and having had sexual relations with an irregular partner during the past 12 months. Odds ratios were calculated for the association between these variables and age, sex, educational level, neighborhood of residence, number of relations in the last 30 days, and whether AIDS tested, by fitting Logistic Regression models (bivariate and multivariate). RESULTS: Over 99% of the sexually active population of Chókwè knew about AIDS and condoms. More than half of the population of Chókwè has a good knowledge of preventive methods and of transmission routes. 72.9% of men and 91.3% of women did not use the condom when having sexual relationships. It was observed that a low educational level implied a lower degree of knowledge about preventive methods (OR=2.48, 95% CI: 1.60-3.84) and about transmission routes (OR=2.49, 95% CI: 1.37-4.52), less condom use and less relations with irregular or sporadic partners. The probability of not using condoms was higher among females, among people living in less privileged districts, with no education (OR=3.79; 95% CI: 1.80-7.99), with regular partners (OR=4.36; 95% CI: 1.93-9.84) and among people who have not had an AIDS test. CONCLUSION: Knowledge of preventive methods and transmission routes is good in more than half of the population of Chókwè. The majority of men and women do not use the condom when having sexual intercourse. Moreover, inequalities may be observed as a function of educational level and district socioeconomic level. Knowledge of preventive practices, mainly among socio-economically disadvantaged groups, must be improved and strategies designed to broaden access to use of condoms by everyone should be implemented.
