Introduccion y objetivos. La posicion socioeconomica se relaciona con la mortalidad cardiovascular. El objetivo de este estudio fue analizar la relacion entre la posicion socioeconomica y sus diferentes indicadores y el riesgo de infarto agudo de miocardio (IAM), y determinar si esta era independiente de los factores de riesgo cardiovascular (FRCV). Metodos. Estudio caso-control apareado por edad, sexo y ano de reclutamiento. Los casos se obtuvieron de un registro hospitalario y los controles, de estudios transversales de base poblacional. La posicion socioeconomica se determino por el nivel de estudios y la clase social basada en ocupacion. Se recogio informacion autodeclarada sobre los FRCV. Resultados. Se incluyo a 1.369 casos y controles. Hubo interaccion entre nivel de estudios y clase social: en los trabajadores no manuales el nivel de estudios se asocio de forma lineal, inversa e independiente de los FRCV con el riesgo de IAM (estudios secundarios, odds ratio [OR] = 1,63; intervalo de confianza [IC] del 95%, 1,16-2,3; estudios primarios, OR = 3,88; IC del 95%, 2,79-5,39) respecto a universitarios; en los trabajadores manuales no se observo una asociacion entre nivel de estudios y riesgo de IAM. Los trabajadores manuales presentaban un exceso de riesgo de IAM respecto a los no manuales universitarios, este exceso de riesgo era independiente de los FRCV en el grupo con estudios primarios (OR = 2,09; IC del 95%, 1,59-2,75). Conclusiones. Hay relacion entre la posicion socioeconomica y el riesgo de IAM. El grupo de la poblacion con nivel de estudios primarios presenta mayor riesgo de IAM que es independiente de los FRCV y de la clase social basada en la ocupacion

OBJECTIVE: To compare the prevalence of lower extremity peripheral artery disease (PAD) and to assess whether age-associated progression in ankle-brachial index (ABI) differs between individuals with chronic immune-mediated inflammatory diseases (CIID) and the general population. METHODS: Pooled analysis with data from individuals aged 50 years and older with ABI measurements, obtained from population-based cross-sectional studies conducted in Catalonia (Spain). Information on three CIID diagnoses (i.e., inflammatory bowel disease, systemic connective tissue disorders, and inflammatory polyarthropathies and spondylopathies, considered as one entity for purposes of analysis) was obtained from electronic medical records. To ascertain the statistical association between PAD and CIID, logistic regression models were fitted and adjusted for age, sex, and cardiovascular risk factors. We tested the interaction between age and CIID diagnosis for ABI values. RESULTS: We included 8799 individuals, 312 (3.6%) with CIID. The age-standardized prevalence of PAD was higher in the CIID group (12% vs. 6% in general population, p = 0.001), and the model adjusted for age, sex, and cardiovascular risk factors also showed higher risk in individuals with CIID [Odds Ratio (95% confidence interval) = 1.65 (1.15-2.38); p = 0.007]. The inflammatory polyarthropathies/spondylopathies diagnosis was significantly associated with PAD in the fully adjusted model [1.80 (1.18-2.75); p = 0.006]. The atherosclerotic process was accelerated in individuals with CIID, compared to the general population (p for interaction

ObjectivesEvidence of the effects of soft drinks consumption on BMI and lifestyle in adult populations is mixed and quite limited. The aim of the present study was to determine the association of soft drinks consumption with BMI and lifestyle in a representative Mediterranean population.DesignTwo independent, population-based, cross-sectional (2000 and 2005) studies. Dietary intake was assessed using a validated FFQ. Weight and height were measured.SettingGirona, Spain.SubjectsRandom sample of the 35- to 74-year-old population (3910 men and 4285 women).ResultsLess than half (41·7 %) of the population consumed soft drinks; the mean consumption was 36·2 ml/d. The prevalence of sedentary lifestyle increased with the frequency of soft drinks consumption (P= 0·025). Daily soft drinks consumption significantly increased the risk of low adherence to the Mediterranean diet (OR = 0·57, 95 % CI 0·44, 0·74v. top tertile of Mediterranean diet score). Multiple linear regression analyses, controlled for potential confounders, revealed that an increment in soft drinks consumption of 100 ml was associated with a 0·21 kg/m2increase in BMI (P= 0·001). Only implausibly low reports of energy consumption showed a null association between soft drinks consumption and BMI.ConclusionsSoft drinks consumption was not embedded in a healthy diet context and was positively associated with BMI and sedentary lifestyle in this Mediterranean population.
