Incidencia y mortalidad por infarto agudo de miocardio en la población mayor de 60 años del área de Tarragona

Background: Population-based data available about the epidemiology of acute myocardial infarction is limited. This study investigated incidence and mortality from infarction among the general population over 60 years in Tarragona. Methods: Cohort study that included 27,204 individuals ≥60 years assigned to nine Primary Care Centers in the Tarragones county (Catalonia, Spain), who were prospectively followed between 01/12/2008 and 30/11/2011. During follow-up, all presumptive episodes of infarction were recruited among cohort members, but only confirmed cases (electrocardiogram and biomarkers confirmation) were included. Results: There were an amount of 359 confirmed episodes of infarction, which means a global incidence rate of 475 episodes per 100,000 person-years (95% CI: 428-527). Incidence was 681 in men and 311in women (p<0.001). According to age, incidence was 277 in 60-69, 632 in 70-79 and 690 per 100,000 in ≥80 years (p<0.001). Incidence was 2,844 cases per 100,000 person-years among those persons whom had history of prior coronary artery disease. Overall 30-day mortality rate was 15.3%, in male 14.9% and in female 16.0% (p=0.776). Conclusion: Incidence was 2.2 times higher in men than in woman and increased considerable by age. It was greater among patients with prior history of coronary artery disease. Mortality was slightly lower in men than in women.Fundamentos: La información procedente de datos de base poblacional sobre la epidemiología del infarto agudo de miocardio es limitada. Este estudio analizó la incidencia y mortalidad por infarto en la población general mayor de 60 años del área sanitaria de Tarragona. Métodos: Estudio de cohortes que incluyó a 27.204 personas ≥60 años adscritas a 9 Áreas Básicas de Salud en la comarca del Tarragonés. Se realizó un seguimiento prospectivo durante 3 años, en los que se registraron todos los episodios de infarto diagnosticados entre los miembros de la cohorte desde 01/12/2008 a 30/11/2011. Se incluyeron exclusivamente los episodios con diagnóstico validado tras revisión de la historia clínica, se excluyeron los casos sin confirmación electrocardiográfica y por biomarcadores. Resultados: Hubo un total de 359 episodios confirmados de infarto, lo cual supuso una incidencia de 475 episodios por 100.000 personas-año (IC 95%: 428-527). La incidencia en hombres fue de 681 por 100.000 y en mujeres de 311 (p<0,001). Por edad fue 277 en el grupo de 60-69, 632 en el de 70-79 y 690 por 100.000 en los sujetos de ≥80 años (p<0,001). La incidencia en las personas con diagnóstico previo de cardiopatía isquémica fue de 2.844 casos por 100.000 personas-año. La mortalidad a los 30 días tras el diagnóstico alcanzó el 15,3%, en hombres 14,9% y en mujeres 16,0% (p=0,776). Conclusiones: La incidencia fue 2,2 veces mayor en hombres que en mujeres y aumentó considerablemente con la edad. También fue superior entre las personas con diagnóstico previo de cardiopatía isquémica. La mortalidad fue ligeramente más baja en hombres que en mujeres

Citizens' perceptions of the presence and health risks of synthetic chemicals in food: results of an online survey in Spain

OBJECTIVE: To explore factors influencing perceptions and viewpoints on the responsibility for the presence of toxic substances in food, on enforcement of laws and regulations that control human exposure to toxic substances in food, and on the effectiveness of such regulations. METHODS: An online survey was completed by 740 individuals from several parts of Spain (median age, 47 years; 67% were women; 70% had completed university studies). RESULTS: Over 87% of respondents said that it was possible that throughout their lives they could have accumulated in their body toxic substances potentially dangerous to their health. The attribution of the responsibility for toxic substances in food to a larger number of social groups was more frequent among respondents who consulted information about the problem more often (odds ratio [OR]: 1.92), who correctly identified factors that increase the likelihood of toxic substances in food being harmful to human health (OR: 2.86), who better knew the health problems that may be caused by such substances (OR: 2.48), and who recognised more food groups that tend to have concentrations of toxic substances potentially harmful to health (OR: 2.92) (all p values <0.001). Women were 65% less likely than men to answer that regulations on toxic substances in food are effective (p<0.001); and so were participants who identified more food groups with potentially toxic concentrations. CONCLUSIONS: Among study participants there was a widespread scepticism and distrust towards the enforcement and effectiveness of laws and regulations that in Spain aim to control human exposure to toxic substances in food.This study is part of the interdisciplinary project “Cuerpos Tóxicos y Etnoepidemiología Sociocultural de la Contaminación Interna por Compuestos Tóxicos Persistentes (CTP) en España” (“Toxic Bodies and Sociocultural Ethnoepidemiology of the Internal Contamination by Persistent Toxic Substances in Spain”), led by C.
