Evaluation of a smoke-free beaches intervention in Barcelona: a quasi-experimental study.

BACKGROUND: We aim to assess the effect of a smoke-free beaches (SFB) intervention in Barcelona on smoking during the 2021 bathing season. METHODS: Quasi-experimental pre-post design (pre-intervention period: 15-28 May; post-intervention period: 29 May-12 September). Based on users' profiles and location, four beaches were assigned to the intervention group (IG) and five to the comparison group (CG). The intervention involved: a mayoral decree (29 May), a communication campaign and beach on-site information. We established two 3 m × 3 m transects per beach from the coastline to the promenade. Trained teams collected smoking-related information in the transects through observations and surveys to beach users. Outcomes are as follows: percentage of people reporting witnessing smoking behaviours the last fortnight and percentage of people observed smoking. We calculated and compared prevalence ratios (PRs) with adjusted Poisson regressions. RESULTS: 3751 interviews (1721 IG; 2030 CG) and 1108 observations (498 IG, 610 CG) were carried out. SFB were associated with a significant reduction in the percentage of people reporting witnessing smoking (IG (pre: 87.2%; post: 49.7%); CG (pre: 86.2%; post: 74.1%); PR (95% CI): 0.7 (0.6 to 0.8)); and in the users observed smoking in the beach (IG (pre: 3.8%; post: 3.0%); CG (pre: 2.3%; post: 9.9%); PR (95% CI): 0.3 (0.3 to 0.4)). Satisfaction scores were 8.3 (IG) and 8.1 (CG) out of 10. CONCLUSION: An SFB intervention is an effective and well-accepted measure to reduce smoking and smokers' visibility. Smoke-free measures should be extended to beaches and other non-regulated outdoor areas.

Evaluation of a Community Intervention to Reduce Harmful Alcohol Consumption among Adult Population: A Study Protocol.

Harmful alcohol consumption is shaped by a complex range of structural, social, and individual determinants that interact with inequality axes, which can be addressed at the community level. Under the framework of Barcelona Health in the Neighborhoods, which is a community strategy to reduce health inequalities in Barcelona's most deprived neighborhoods, a community steering group will co-design a multicomponent community intervention. Aims: to assess its effects on: (1) alcohol accessibility, availability, and consumption at the environmental level, and (2) psychosocial and cognitive determinants of harmful alcohol consumption at the individual level. Methods: Quasi-experimental design with a comparison group, and pre- and post-intervention measures. Three Barcelona neighborhoods will be assigned to the intervention or comparison group based on three criteria: healthcare data on alcohol use, socioeconomic characteristics, and population size. The intervention includes activities promoting community mobilization, law enforcement, and communication campaigns in the intervened neighborhoods. Non-participant observations in standardized census sections will be performed in public spaces to collect information on three outcomes: alcohol accessibility, availability, and signs of alcohol consumption. Data collection includes a survey to a sample of 622 subjects to detect differences on these outcomes: risk awareness, knowledge, and self-efficacy about harmful alcohol consumption and drinking patterns. Discussion: This protocol to assess the effects of a multicomponent community intervention on harmful alcohol consumption at the environmental and population level will provide evidence on effective community health interventions and enable informed decisions for policy makers. This protocol could also be used as an implementation guide for studies aimed at reducing harmful drinking in cities with similar characteristics.

Health Inequalities by Sexual Orientation: Results from the 2016-2017 Barcelona Health Survey.

Purpose: The aim of this study was to assess health inequalities by sexual attraction in the 2016-2017 Barcelona population, stratifying by sex. Methods: Data came from the 2016-2017 Barcelona Health Survey, where 3362 adults answered among other instruments the EuroQol-5 dimensions-5 levels (EQ-5D-5L), which measures five dimensions and summarizes health-related quality of life into a single utility index score. To assess health differences by sexual attraction, we constructed Tobit models for the EQ-5D index score and Poisson regression models for the EQ-5D dimensions. Nested models were constructed to examine the mediating role of discrimination and health-related variables. Results: After adjusting for sociodemographic variables, women feeling attraction to more than one sex showed a lower EQ-5D index score (worse health) than those with only other sex attraction (-0.042, p = 0.012), and higher prevalence of problems with mobility, usual activities, and anxiety/depression with the following adjusted prevalence ratios (aPR) and confidence intervals (CIs): 1.79 (95% CI 1.05-3.05), 1.84 (95% CI 1.05-3.21), and 1.76 (95% CI 1.27-2.43). Women feeling attraction only to their same sex also presented higher prevalence of anxiety/depression (aPR = 1.46, CI 95% 1.10-1.92). In contrast, differences were not observed for men. Conclusion: Women, but not men, feeling attraction to more than one sex and only same-sex attraction in Barcelona in 2016-2017 presented worse health than those feeling only other sex attraction, with discrimination playing a mediating role in explaining such inequalities. These results among women indicate the need to develop public health strategies in Barcelona addressed to lesbian and bisexual women, considering the intersection of gender and sexual orientation.

Neighbourhood income inequalities in mental health in Barcelona 2001-2016: a Bayesian smoothed estimate.

OBJECTIVE: Obtaining reliable health estimates at the small area level (such as neighbourhoods) using survey data usually poses the problem of small sample sizes. To overcome this limitation, we explored smoothing techniques in order to estimate poor mental health prevalence at the neighbourhood level and analyse its profile by income in Barcelona city (Spain). METHOD: A Bayesian smoothing model with a logit-normal transformation was applied to four repeated cross-sectional waves of the Barcelona health survey for 2001, 2006, 2011 and 2016. Mental health status was identified from the 12-item General Health Questionnaire. Income inequalities were analysed with neighbourhood income in quantiles for each year and trends in the pooled analysis. RESULTS: The prevalence of poor mental health ranged from 14.6% in 2001 to 18.9% in 2016. The yearly difference between neighbourhoods was 12.4% in 2001, 16.7% in 2006, 14.2% in 2011, and 20.0% in 2016. The odds ratio and 95% credible interval (95%CI) of experiencing poor mental health was 1.40 times higher (95%CI: 1.02-1.91) in less advantaged neighbourhoods than in more advantaged neighbourhoods in 2001, 1.61 times higher (95%CI: 1.01-2.59) in 2006 and 2.31 times higher (95%CI: 1.57-3.40) in 2016. CONCLUSIONS: This study shows that the Bayesian smoothed techniques allows detection of inequalities in health in neighbourhoods and monitoring of interventions against them. In Barcelona, mental health problems are more prevalent in low-income neighbourhoods and raised in 2016.

Confidence in a Vaccine against COVID-19 among Registered Nurses in Barcelona, Spain across Two Time Periods.

OBJECTIVE: To report the vaccine hesitancy (VH) for a vaccine against COVID-19 in registered nurses in Barcelona, with measurements taken at two stages, prior to the vaccination campaign and once 75% vaccination coverage had been reached. METHODS: A self-completed online survey was administered in December 2020 and again in July 2021 through the College of Nurses of Barcelona. It measured the prevalence of VH against a government-approved vaccine recommended by their employer, their intention to be vaccinated, perceptions of disease risk and vaccine protection, attitudes and beliefs to vaccination and social norm. Bivariate analysis according to VH and application time are presented. RESULTS: 2430 valid responses were obtained in the first measurement and 2027 in the second. At both times, 86% were women and 69% worked mainly in the public sector. Prior to the vaccine availability, VH was 34.2%, decreasing to 17.9%. Risk perceptions were significantly lower in those with VH compared to non-VH, in all groups studied and at both times, while safety and efficacy perceptions increased in all groups, significantly less in VH. The greatest benefit of the COVID-19 vaccine is perceived by pharmaceutical companies. VH nurses perceived a more hesitant social environment. CONCLUSION: As the vaccination was rolled out, VH in nurses declined, with time improving the confidence in the safety and efficacy of the vaccines. Risk perceptions also decreased over time, except for the perception of severity in HCW where it increased. Trust in institutions impacts trust in vaccines.

Multi-level policy responses to tackle socioeconomic inequalities in the incidence of COVID-19 in a European urban area.

BACKGROUND: Spain has been hit hard by COVID-19 since March 2020, especially in its metropolitan areas. We share experiences from Barcelona in measuring socioeconomic inequalities in the incidence of COVID-19 in the different waves, and in implementing coordinated and equity-oriented public health policy responses. METHODS: We collected daily data on confirmed COVID-19 cases, geocoded the address of residence to assign each case to one of the 73 neighborhoods and 1068 census tracts, and calculated the cumulative incidence of COVID-19 by neighborhood and five income groups (quintiles of census tracts) by sex across four waves of the pandemic. We adjusted hierarchical Bayesian spatial models to obtain the relative risk (RR) of cumulative incidences in each quintile compared with the richest areas. A variety of public health policies implemented to tackle the pandemic and especially these inequalities in COVID-19 incidence and vaccination are selected and described. RESULTS: Area-level income inequalities in the incidence of COVID-19 were present at different degree in all four waves. In the second wave (10/1/2020 to 12/6/2020), RR for the poorest income quintile census tracts compared with the richest was 1.43 (95% credible interval-CI-: 1.22-1.67) for men and 1.58 (95% CI: 1.35-1.83) for women. Later, inequalities in vaccination coverage also arose. Equity-oriented policy responses included: "health hotels" or home delivery of basic products for individuals with COVID-19 and without adequate conditions for isolation; new emergency facilities for homeless people, including those with active drug use; mass screening in high incidence areas; contingency plans for nursing homes and schools; adapting community health programs for their early reactivation; digital self-appointment support points and community vaccination days. CONCLUSION: COVID-19 hit Barcelona neighborhoods unequally, with variations between waves. The rapid availability of geolocalized data and by socioeconomic level helped public authorities to implement targeted policies and collaborative interventions for the most vulnerable populations. Further studies would be needed to evaluate their impact.

Vaccine hesitancy among paediatric nurses: Prevalence and associated factors.

OBJECTIVE: This study describes the prevalence of vaccine hesitancy associated with the Catalan systematic childhood vaccination calendar and some related psychosocial determinants among paediatric primary care nurses in Barcelona (Spain). METHODS: Cross-sectional descriptive study. In 2017 we invited the paediatric nurses (N = 165) working in Barcelona public primary health centres with paediatric departments (N = 41) to participate. They answered a questionnaire with sociodemographic and behavioural variables: severity and perceived probability of contracting the diseases of the vaccines in the vaccination schedule; safety and protection offered by each vaccine; and beliefs, social norms, and knowledge about vaccines. Outcome variable was vaccine hesitancy, dichotomized into not hesitant (nurses who would vaccinate their own offspring), and hesitant (including those who would not vaccinate them, those who had doubts and those who would delay the administration of one or more vaccines). We performed bivariate analysis and adjusted logistic regression models. RESULTS: 83% of paediatric nurses (N = 137) agreed to participate. 67.9% had the intention to vaccinate their children of all the vaccines in the systematic schedule. 32.1% of nurses experienced vaccine hesitancy, especially about the HPV (21.9%) and varicella (17.5%) vaccines. The multivariate analysis suggests associations between hesitancy and low perception of the severity of whooping cough (aOR: 3.88; 95%CI:1.32-11.4), low perception of safety of the HPV vaccine (aOR:8.5;95%CI:1.24-57.8), the belief that vaccines are administered too early (aOR:6.09;95%CI:1.98-18.8), and not having children (aOR:4.05;95%CI:1.22-13.3). CONCLUSIONS: Although most paediatric nurses had the intention to vaccinate their own children, almost one-third reported some kind of vaccine hesitancy, mainly related to doubts about HPV and varicella vaccines, as well as some misconceptions. These factors should be addressed to enhance nurses' fundamental role in promoting vaccination to families.

Improving mental health and wellbeing in elderly people isolated at home due to architectural barriers: A community health intervention.

OBJECTIVES: To explore the health effects of a community health intervention on older people who are isolated at home due to mobility problems or architectural barriers, to identify associated characteristics and to assess participants' satisfaction. DESIGN: Quasi-experimental before-after study. SETTING: Five low-income neighbourhoods of Barcelona during 2010-15. PARTICIPANTS: 147 participants, aged ≥59, living in isolation due to mobility problems or architectural barriers were interviewed before the intervention and after 6 months. INTERVENTION: Primary Health Care teams, public health and social workers, and other community agents carried out a community health intervention, consisting of weekly outings, facilitated by volunteers. MEASUREMENTS: We assessed self-rated health, mental health using the General Health Questionnaire (GHQ-12), and quality of life through the EuroQol scale. Satisfaction with the programme was evaluated using a set of questions. We analysed pre and post data with McNemar tests and fitted lineal and Poisson regression models. RESULTS: At 6 months, participants showed improvements in self-rated health and mental health and a reduction of anxiety. Improvements were greater among women, those who had not left home for ≥4 months, those with lower educational level, and those who had made ≥9 outings. Self-rated health [aRR: 1.29(1.04-1.62)] and mental health improvements [ß: 2.92(1.64-4.2)] remained significant in the multivariate models. Mean satisfaction was 9.3 out of 10. CONCLUSION: This community health intervention appears to improve several health outcomes in isolated elderly people, especially among the most vulnerable groups. Replications of this type of intervention could work in similar contexts.

Community-Based Interventions to Reduce Alcohol Consumption and Alcohol-Related Harm in Adults.

Alcohol consumption was associated with 3 million deaths worldwide in 2016. Although community action has proven to be effective and has become a priority area of the global strategy to reduce alcohol consumption, there is a gap in the knowledge of community interventions to reduce alcohol use among adults. This study aims to analyze the evidence on effective community-based interventions to reduce alcohol consumption and harm among adults and to identify their components and underlying theories. Search strategy involved five databases (January 2000-March 2020). We included multicomponent, evaluated, and community interventions addressing to adults in urban settings of high-income countries. Furthermore, two conceptual frameworks were adapted to identify the social determinants of alcohol related harms and modifiable factors through community interventions. The initial search yielded 164 articles. The final sample included eight primary studies. Six of them were effective and shared three components (community mobilization; law enforcement and media campaigns), they combined approaches at individual and environmental levels addressing structural determinants of health and some cultural aspects related to consumption. Health outcomes focused mainly on reducing consumption, modifying patterns and acute effects on health. Few studies addressed social problems arising from harmful consumption. This review has identified several effective community-based interventions to reduce harmful use of alcohol among adults as well as some mechanisms and theories supporting them. It also provides a framework to guide new designs, with potential evidence of factors, as well as possible combinations of methods to improve health at community level across different settings and contexts.

Barcelona Salut als Barris: Twelve years' experience of tackling social health inequalities through community-based interventions.

Community health can reduce inequalities in health and improve the health of the most disadvantaged populations. In 2007, Barcelona Salut als Barris (Barcelona Health in the Neighbourhoods) was launched, a community health programme to reduce social inequalities in health. In 2018, this programme reached the 25 most disadvantaged neighbourhoods of the city. This article shares the lessons learned after 12 years of work. The programme was initially funded by a research grant and the funds were maintained during the economic crisis and were tripled when the programme became a political priority in the last municipal government. During the 12-year period, partnerships with stakeholders were generally stable and productive. Maximum community participation was obtained in the detection of health assets and needs and in action plans. During 2018, Barcelona Salut als Barris worked with more than 460 agents that co-produced 183 interventions involving more than 13,600 people. Most of the interventions assessed showed improvements in the health of participants, which could help to reduce health inequalities. The greatest difficulties were: a) citizen participation, b) the sustainability of working groups over the years, c) conflicts of interest, d) the sustainability of interventions, e) reaching certain minority groups and f) evaluation. The increase in resources in the last period contributed to the maturity and expansion of the programme. Key factors in its scope and results were political will, strong technical capacity and methodology, strong intersectoral partnerships and continued community work.
