Evolución De La Mortalidad Prematura Fuertemente Relacionada Con Alcohol en España Durante 2001-2022 Según Comunidad Autónoma
Assessing educational disparities in Covid-19 related excess mortality in Spain
Introduction: Data on the increase in mortality during the COVID-19 pandemic based on individuals' socioeconomic positions are limited. This study examines this increase in mortality in Spain during the epidemic waves of 2020 and 2021. Methods: We calculated the overall and cause-specific mortality rates during the 2017-2019 pre-pandemic period and four epidemic periods in 2020 and 2021 (first, second, third-fourth, and fifth-sixth waves). Mortal…

Heavy Drinking by Occupation in Spain
Changes in all-cause and cause-specific mortality by occupational skill during Covid-19 epidemic in Spain
BACKGROUND: There is little information on the differential impact of the COVID-19 pandemic on mortality by occupation. The objective was to examine changes in mortality during the COVID-19 period compared with the prepandemic period in different occupational groups in Spain. METHODS: Average mortality in the entire period 2020-2021, and each of its semesters, was compared, respectively, with the average mortality in the entire period 2017-2019, …
Abrupt peaks in perceived risk of occasional drug use after changing the question order in a repeated self-administered survey
Background: Question-order changes in repeated surveys can distort comparisons. We want to describe the evolution of drug risk perceptions among Spanish adolescents and assessing whether the 2006 peaks in perceived risk of occasional drug use can be explained by question-order changes. Methods: The subjects were secondary students from a biennial national survey during 2000-2012. A one-off intervention was applied in 2006, replacing the two-adjac…
Estimating the Prevalence of Recreational Opioid Use in Spain Using a Multiplier Method
Educational Gradients in Drinking Amount and Heavy Episodic Drinking among Working-Age Men and Women in Spain
Alcohol-related harm decreases as socioeconomic position increases, although sometimes the opposite happens with alcohol intake. The objective was to know the educational gradient in monthly measures of drinking amount and heavy episodic drinking (HED) among people aged 25−64 years in Spain from 1997−2017. Such gradient was characterized with the relative percent change (PC) in drinking measures per year of education from generalized linear regre…

Macroeconomic fluctuations, changes in lifestyles and mortality from diabetes
BACKGROUND: To evaluate trends in diabetes-related health behaviours and mortality from diabetes and other chronic diseases in the Spanish population before, during and after the 2008 economic crisis. METHODS: Annual population measurements were obtained from national surveys and administrative registries for 2004-2016. Using segmented regression analysis, we calculated the annual percentage change (APC) in 2004-2007, 2008-2010, 2011-2013 and 201…
Mortality in Spain in the Context of the Economic Crisis and Austerity Policies
Objectives. To analyze the mortality trend in Spain before, during, and after the economic crisis and austerity policies. Methods.

Results. All-cause mortality rate decreased during the period 2001 to 2016, although we f…
Effect of ageing and time since first heroin and cocaine use on mortality from external and natural causes in a Spanish cohort of drug users
Intimate partner violence against young women
BACKGROUND: The magnitude of intimate partner violence (IPV) in young women is a source of increasing concern. The prevalence of IPV has not been analysed in Europe as a whole. The objective was to assess the prevalence and main characteristics of experiencing physical and/or sexual and psychological-only IPV among young women in the European Union and to identify individual and contextual associated risk factors. METHODS: We analysed a cross-sec…
Mortality risk during and after opioid substitution treatment
Changes in directly alcohol-attributable mortality during the great recession by employment status in Spain
Background Macroeconomic fluctuations can impact differentially on alcohol-related problems across sociodemographic groups. We assess trend changes in directly alcohol-attributable (DAA) mortality in the population aged 25–64 during the post-2008 recession in Spain according to employment status and other sociodemographic factors. Methods Nationwide cohort study covering 21.9 million people living in Spain in 2001. People were classified by emplo…
Assessing gender disparities in excess mortality of heroin or cocaine users compared to the general population
High hepatitis C virus prevalence and incidence in a community cohort of young heroin injectors in a context of extensive harm reduction programmes
BACKGROUND: Cohort studies on hepatitis C virus (HCV) among drug injectors are scarcer than studies on HIV. Combined harm reduction interventions (HRIs) can prevent HCV infection. Spain has a medium-high coverage of HRIs. METHODS: 513 young heroin users who injected drugs in the past 12 months (recent injectors) were street-recruited in 2001-2003 and followed until 2006 in three Spanish cities; 137 were anti-HCV seronegative, 77 of whom had ≥1 fo…
Area-level socioeconomic context, total mortality and cause-specific mortality in Spain
Has health in Spain been declining since the economic crisis
BACKGROUND: The economic recession starting in 2008 may be having negative effects on health. PURPOSE: We aimed to identify and characterise changes in trends in 15 health indicators in Spain during the recession. METHODS: Joinpoint regression and average annual percent change (AAPC) were used to compare trends. RESULTS: Premature mortality rates from several causes of death, except from cancer, showed statistically significant downward trends du…

Injecting and HIV prevalence among young heroin users in three Spanish cities and their association with the delayed implementation of harm reduction programmes
Objectives: To evaluate changes in the prevalence of HIV infection among young heroin users in three Spanish cities, and their association with harm reduction programmes (HRPs). Methods: Two cross sectional studies. The 1995 study included 596 users; half were street recruited and half were recruited at drug treatment centres. The 2001–03 study included 981 street recruited users. Face to face interviews were conducted using a structured question…

Cocaine use among heroin users in Spain
STUDY OBJECTIVE: To describe the prevalence and patterns of use of crack and cocaine hydrochloride among heroin users in Spain.

SETTING: Three cities with different prevalences of heroin use by smoking: high (Seville), intermediate (Madrid), and low (Barc…
The impact of drug-related deaths on mortality among young adults in Madrid
The trend from 1983 to 1990 of drug-related mortality (defined as the sum of deaths from acute drug reactions and the acquired immuno-deficiency syndrome [AIDS] in drug users) among the population 15 to 39 years of age in Madrid, Spain, was studied and compared with mortality from all causes. All of the mortality rates increased from 1983 to 1990: all causes, from 101/100,000 to 148/100,000; acute drug reactions, from 3/100,000 to 15/100,000; and…
