Does lifestyle explain the relationship between socioeconomic position and multimorbidity of cancer and cardiometabolic diseases? A mediation analysis applied to the European Prospective Investigation…
BACKGROUND: Multimorbidity is socially patterned, with lower socioeconomic position (SEP) linked to higher risk. We examined whether a Healthy Lifestyle Index (HLI) mediates the SEP-multimorbidity association and whether pathways differ by sex. METHODS: We used data from 244 886 participants in the European Prospective Investigation into Cancer and Nutrition study. HLI was derived from smoking, alcohol consumption, physical activity, body mass in…
Relationships Between (Poly)phenol Intakes and Dementia Risk in the Epic-Spain Dementia Cohort
Influence of One-Carbon Metabolism-Related Molecular Variants and Nutrients Intake on Breast Cancer Risk in the Epiceurope Cohort
Mortality attributable to modifiable lifestyle factors in the Spanish cohort of the European prospective investigation into cancer and nutrition (Epic) study
Shifting from any risk factor to a healthier lifestyle would reduce mortality in both sexes. However, in women, alcohol consumption did not influence mortality risk and only BMI was associated with mortality risk attributable body adiposity
Quantifying the environmental and food biodiversity impacts of ultra-processed foods
Objective: While associations of ultra-processed food (UPF) consumption with adverse health outcomes are accruing, its environmental and food biodiversity impacts remain underexplored. This study examines associations between UPF consumption and dietary greenhouse gas emissions (GHGe), land use and food biodiversity. Design: Prospective cohort study. Linear mixed models estimated associations between UPF intake (g/d and kcal/d) and GHGe (kg CO 2 …
Burden of postmenopausal breast cancer attributable to excess body weight
BACKGROUND: 10% of postmenopausal breast cancer cases are attributed to a high body mass index (BMI). BMI underestimates body fat, particularly in older women, and therefore the cancer burden attributable to obesity may be even higher. However, this is not clear. CUN-BAE (Clínica Universidad de Navarra-Body Adiposity Estimator) is an accurate validated estimator of body fat, taking into account sex and age. The objective of this study was to comp…
Antecedentes familiares de primer grado como factor de riesgo en el cáncer colorrectal
El objetivo de este estudio es evaluar la asociación entre antecedentes familiares (AF) de primer grado y cáncer colorrectal (CCR). Se incluyeron 2857 controles y 1360 casos de CCR, del estudio MCC-Spain. La odds ratio (OR) y el intervalo de confianza del 95% (IC95%) de los AF de primer grado y el CCR se estimaron mediante regresión logística no condicional según la localización tumoral en los casos. Los AF de primer grado duplicaron el riesgo de…
Protocolo del Estudio Poblacional Multinivel de las Desigualdades Socioeconómicas en la Distribución Geográfica de la Incidencia, la Mortalidad y la Supervivencia Neta del Cáncer en España
La incidencia y la mortalidad brindan información sobre la carga de la morbilidad del cáncer y los años potenciales de vida perdidos debido al cáncer. Se ha desarrollado el Índice de Privación (IP) como una medida estandarizada para medir la privación socioeconómica en España a nivel de sección censal. Además, se puede combinar la información del IP con variables ecológicas poblacionales y los datos de los Estudios Europeos de Alta Resolución en …
Altitude and Sars-CoV-2 Infection in the First Pandemic Wave in Spain
After the first pandemic wave, a nationwide survey assessed the seroprevalence of SARS-CoV-2 antibodies in Spain and found notable differences among provinces whose causes remained unclear. This ecological study aimed to analyze the association between environmental and demographic factors and SARS-CoV-2 infection by province. The seroprevalence of SARS-CoV-2 antibodies by province was obtained from a nationwide representative survey performed in…
Dietary Constituents
The aim of this study was to characterize the relationship between the intake of the major nutrients and prognosis in breast cancer. A cohort based on 1350 women with invasive (stage I-IV) breast cancer (BC) was followed up. Information about their dietary habits before diagnosis was collected using a semi-quantitative Food Frequency Questionnaire. Participants without FFQ or with implausible energy intake were excluded. The total amount consumed…
Quality of Life in a Cohort of 1078 Women Diagnosed with Breast Cancer in Spain
Breast cancer is the most frequent cause of tumors and net survival is increasing. Achieving a higher survival probability reinforces the importance of studying health-related quality of life (HR-QoL). The main aim of this work is to test the relationship between different sociodemographic, clinical and tumor-intrinsic characteristics, and treatment received with HR-QoL measured using SF-12 and the FACT/NCCN (National Comprehensive Cancer Network…
No association between fish consumption and risk of stroke in the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (Epic-Spain)
Objective To prospectively assess the associations between lean fish, fatty fish and total fish intakes and risk of stroke in the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC-Spain). Design Fish intake was estimated from a validated dietary questionnaire. Cox proportional hazards regression models were used to assess the association between the intakes of lean fish, fatty fish and total fish and stroke …
Effectiveness of the trivalent influenza vaccine in Navarre, Spain, 2010–2011
The 2010-2011 seasonal influenza vaccine had a moderate protective effect in preventing laboratory-confirmed influenza
P2-200 Population trends in the incidence and outcomes of acute myocardial infarction in a Mediterranean region of southern Europe
Introduction The aim of this population-based study was to examine trends in the myocardial infarction incidence and mortality rates between 2000 and 2009 in Navarre, Spain. Methods All admissions for myocardial infarction in a region of over half a million inhabitants from January 2000 to December 2009 were identified from the hospitals discharge databases. Age- and sex-adjusted incidence and 30-day and 30–365-day mortality rates were calculated…
