Association of drought conditions and heavy rainfalls with the quality of drinking water in Barcelona (2010-2022).

BACKGROUND: Climate change influences the incidence and scope of climate extreme events that affect communities and the environment around the world. In an urban context such as Barcelona, these climate extremes can have a negative impact on drinking water quality. The worsening of drinking water quality can have important repercussions on human health, leading to the appearance of different diseases. OBJECTIVE: Investigate the association between climate extremes, in particular heavy rainfall events and drought conditions, and the drinking water quality in the city of Barcelona from 2010 to 2022. METHODS: We conducted a daily retrospective time-series study using data covering 13 years of daily monitoring of conductivity, nickel, turbidity and trihalomethanes parameters of raw water in the Llobregat River catchment area and treated water in the Drinking Water Treatment Plant (DWTP) Sant Joan Despí. We used river flow as a proxy for drought conditions and heavy rainfall events. We analyzed short-term associations between river flow rate and quality parameters in raw and treated water using generalized linear regression with distributed lag-non-linear models (DLNM). RESULTS: A low flow, as an indicator of drought condition or low rainfall, was significantly associated with an increase in conductivity in raw water and nickel in both raw and treated water. A high flow, as an indicator of heavy rainfall events, was significantly associated with an increase of turbidity in raw water, and a decrease in all other quality parameters. IMPACT STATEMENT: This study provides novel evidence that climate extremes have an impact on the quality of drinking water in urban areas with a Mediterranean climate. The findings of this study are significant because they suggest that as the frequency and intensity of climate extremes increase due to climate change, there will be further challenges in managing and treating drinking water, which could have a detrimental effect on public health. This study serves as an important reminder of the need to strengthen and accelerate adaptation actions in water management to ensure an adequate supply of drinking water that protects the people's health.

¿Cómo influye la situación laboral en los efectos de la inseguridad residencial sobre la salud? / How does employment status influence the effects of residential insecurity on health?

OBJETIVO: Analizar los efectos de la inseguridad residencial sobre la salud y si estos son modificados por la situación laboral en personas participantes en el programa Treball als Barris, en Barcelona, entre 2015 y 2016. MÉTODO: Se realizó un estudio longitudinal con 469 personas a las cuales se les realizó una encuesta, basal y al año de seguimiento, que incluyó información sociodemográfica, residencial, laboral y de salud. Se construyó una variable de trayectorias residenciales con las situaciones al inicio y después del seguimiento. Luego se realizó un análisis descriptivo, se ajustaron modelos de regresión para estimar el efecto de la inseguridad residencial y de la situación laboral sobre la salud, y finalmente se analizó la interacción. RESULTADOS: La inseguridad residencial afectó principalmente la salud de las mujeres (la razón de prevalencia [RP] de mala salud percibida de quienes se mantuvieron en inseguridad residencial fue de 2,29, con un intervalo de confianza del 95% [IC95%] de 1,36-3,84, en comparación con quienes se mantuvieron en seguridad residencial), mientras que en los hombres fue la situación laboral la que tuvo efectos significativos sobre la salud (los desempleados sin subsidio ni prestación presentaron RP de mala salud percibida de 3,16, con IC95% de 1,02-6,15, comparados con quienes trabajaban). Además, parece existir una interacción de la inseguridad residencial y la situación laboral en los efectos sobre la salud mental de los hombres. CONCLUSIÓN: La inseguridad residencial es un fenómeno que se ha intensificado en los últimos años, tiene efectos negativos sobre la salud y podría interactuar con otros determinantes sociales, como el empleo, fundamentalmente en la salud mental de los hombres

OBJECTIVE: This study aims to analyse the effects of housing insecurity on health and whether they are modified by employment status of people belonging to the Treball als Barris programme in Barcelona (Spain) between 2015 and 2016. METHOD: We conducted a longitudinal study using a survey which included sociodemographic, employment and housing status information. This was administered to 469 individuals at baseline and after one year of follow-up. We then carried out a descriptive analysis and fitted regression models to estimate the effects of housing insecurity and employment status on health, and the interaction between them. RESULTS: Among women, we found negative effects of housing insecurity on health (the prevalence ratio [PR] of poor self-reported health among women with housing insecurity was 2.29, with a 95% confidence interval [95%CI] of 1.36-3.84, compared to those in secure housing), while, among men, the main effects on health were due to employment status (PR of poor self-reported health among men who were unemployed without subsidy was 3.16 [95%CI: 1.02-6.15] compared to those who were employed after follow-up). In addition, the results suggest an interaction between housing and employment status on mental health among men. CONCLUSION: Housing insecurity rates have increased in recent years. It produces negative effects on health and can interact with other social determinants such as employment, mainly on men's mental health

The impact of Active Labour Market Policies on health outcomes: a Scoping review.

BACKGROUND: Since the last Western great recession of 2008, an increasing interest on the effects of Active Labour Market Policies (ALMPs) on improving health has emerged. The aim of our review is to synthesize evidence on the effectiveness of ALMPs and whether some types of ALMP are more effective. METHODS: Using the Scoping review methodology, we conducted a literature review in PubMed/MEDLINE, Scopus and Web of Science and selected articles published between 1990 and 2017 in high income countries. We applied four sequential phases of document screening to the list of retrieved articles. RESULTS: Of the 416 documents detected in the search, 36 documents were finally selected. Most of them focused on mental health and related components (72.2%) and found positive results at least in one outcome (80.6%). The ALMPs reported mainly attempt to build capacity through job search assistance (31.6%) with a component on mental health, showing positive results on health; some offer job training (16.7%) and few subsidized employment (8.3%), showing more controversial results, although mostly positive. The rest include a combination of different types of ALMPs. CONCLUSIONS: This review shows that ALMPs have a positive impact on health and quality of life. There are relatively few studies of the impact of ALMPs on general health, and most of the studies found are focused on Anglo-Saxon and Nordic countries. The most significant knowledge gaps are the mechanisms involved in achieving this improvement, and above all the differential health impacts according to axes of inequality and welfare state.

Employment in the neighborhoods of Barcelona: health effects of an active labor market program in Southern Europe.

BACKGROUND: The aim of this study was to analyze the changes in self-perceived health status and mental health among participants in an active labour market policy (ALMP) of Barcelona, and to assess whether the results differed according to the participants' social characteristics and their program trajectories. METHODS: A pre-post intervention study was designed, including unemployed people participating in a return-to-work ALMP in 13 deprived neighborhoods of Barcelona; using one survey upon entering the program (pre), and another 1 year later (post). We assessed the prevalence of poor self-perceived health status and poor mental health (Goldberg-12 questionnaire) in both periods of time. We fit five Poisson regression models using generalized estimating equations (GEE) to measure changes in self-perceived health and mental health between pre- and post-intervention. RESULTS: About 696 individuals (48% women) participated in the study, mainly manual workers. In both sexes, mental health improved (prevalence ratio [PR]-comparing post- and pre-periods for women: 0.49, 95% confidence interval [CI]: 0.39-0.61 and men: PR: 0.41, 95% CI: 0.32-0.53), whereas self-perceived health status remained stable or worsened. Men who remained unemployed reported poorer self-perceived health status, while no such association was observed among women. CONCLUSIONS: This study shows a mental health improvement among male and female participants.

Social and material determinants of health in participants in an active labor market program in Barcelona.

BACKGROUND: Unemployment affects the physical and mental health of affected individuals, which can be explained by its direct effect on worsening finances due to the lack of income as well as by its negative psychosocial effects. "Employment in the Neighborhoods" return to work program was implemented in Barcelona specifically in the neighborhoods characterized with a greater economic deprivation and by high unemployment to improve personal and occupational abilities and skills of the participants to reintegrate them into the workforce. The aim of this study is to determine the association between the lack of economic resources and psychosocial factors with respect to mental health and self-rated health in unemployed persons participating in the program "Employment in the Neighborhoods". METHODS: Cross-sectional study. Data collected from a self-administered questionnaire. Generalized linear models were constructed, adjusted by age and social class, to estimate prevalence ratios and analyze any possible association between economic resources, psychosocial factors and poor self-rated health and mental health. RESULTS: Nine hundred forty-eight persons of 2763 participants in the "Employment in the Neighborhoods" program completed the questionnaire. 46.9% were women. 72.5% of women and 61.9% of men were at risk of poor mental health and 25.5% of women and 21.1% of men reported poor self-rated health. Low self-esteem [women: PR 1.88 95%CI (1.24-2.84); men: PR 2.51 95%CI (1.57-4.02)] and medium social support [2.01 (1.30-3.09)], in men, and low social support [1.74 (1.13-2.68)] in women are associated with worsening of self-rated health. In men, low self-esteem [1.40 (1.19-1.64)] and delay in paying bills [1.38 (1.17-1.64)] were associated with the risk of poor mental health; in women were associated low self-esteem [1.27 (1.11-1.44)] and received a non-contributory allowance [1.37 (1.09-1.74)]. CONCLUSIONS: Economic resources, self-esteem and social support are necessary for good general and mental health among unemployed persons. The high prevalence of poor mental health among persons participating in the active labor market program "Employment in the Neighborhoods" could be due to a substantial deficit in these factors.
