Identifying Adverse Events in Patients Hospitalized in Isolation or Quarantine Due to COVID-19.

BACKGROUND: This study evaluated the adverse events of COVID-19 isolation or quarantine in patients with nosocomial SARS-CoV-2 infection admitted to the Hospital Universitario Insular de Gran Canaria. METHODS: This is a retrospective cohort study with 30-day follow-up of 126 patients diagnosed with nosocomial COVID-19 through polymerase chain reaction test, between May 1 and June 30, 2022, in a 500-bed university hospital in the island of Gran Canaria. RESULTS: Between May 1 and July 30, 2022, a total of 2250 patients were admitted to the Hospital Universitario Insular de Gran Canaria; 126 of them were diagnosed with nosocomial COVID-19 through a polymerase chain reaction test. The rate of nosocomial COVID-19 infection was 5.6%. From the 126 patients of the study population, 27 experienced an adverse event (21.4%) and 2 experienced 2 adverse events (1.6%) due to COVID-19 isolation or quarantine. Thus, a total of 31 adverse events occurred in 29 patients. These events included the following: delay in transfer to other centers of 11 patients who were pending of receiving a negative COVID-19 test result (35.5%), delay or cancellation of diagnostic tests in 9 patients (29%), delay or cancellation of doctor visit in 7 patients (22.6%), and delay or cancellation of surgical or other interventions in 4 patients (12.9%). CONCLUSIONS: Because of the adverse consequences of nosocomial COVID-19 infection in hospitalized patients, measures should be observed for the prevention and control of nosocomial infection transmission, and adverse events related to patient safety issues in health care in isolated or quarantined COVID-19 patients should be prevented.

Lifting COVID-19 mitigation measures in Spain (May-June 2020).

Introduction: The state of alarm was declared in Spain due to the COVID-19 epidemic on March 14, 2020, and established population confinement measures. The objective is to describe the process of lifting these mitigation measures. Methods: The Plan for the Transition to a New Normality, approved on April 28, contained four sequential phases with progressive increase in socio-economic activities and population mobility. In parallel, a new strategy for early diagnosis, surveillance and control was implemented. A bilateral decision mechanism was established between the Spanish Government and the autonomous communities (AC), guided by a set of qualitative and quantitative indicators capturing the epidemiological situation and core capacities. The territorial units were established ad-hoc and could be from Basic Health Zones to entire AC. Results: The process run from May 4 to June 21, 2020. AC implemented plans for reinforcement of core capacities. Incidence decreased from a median (50% of territories) of 7.4 per 100,000 in 7 days at the beginning to 2.5 at the end. Median PCR testing increased from 53% to 89% of suspected cases and PCR total capacity from 4.5 to 9.8 per 1000 inhabitants weekly; positivity rate decreased from 3.5% to 1.8%. Median proportion of cases with traced contacts increased from 82% to 100%. Conclusion: Systematic data collection, analysis, and interterritorial dialogue allowed adequate process control. The epidemiological situation improved but, mostly, the process entailed a great reinforcement of core response capacities nation-wide, under common criteria. Maintaining and further reinforcing capacities remained crucial for responding to future waves.

Introducción: El 14 de marzo de 2020 España declaró el estado de alarma por la pandemia por COVID-19 incluyendo medidas de confinamiento. El objetivo es describir el proceso de desescalada de estas medidas. Métodos: Un plan de transición hacia una nueva normalidad, del 28 de abril, incluía 4 fases secuenciales incrementando progresivamente las actividades socioeconómicas y la movilidad. Concomitantemente, se implementó una nueva estrategia de diagnóstico precoz, vigilancia y control. Se estableció un mecanismo de decisión bilateral entre Gobierno central y comunidades autónomas (CCAA), guiado por un panel de indicadores cualitativos y cuantitativos de la situación epidemiológica y las capacidades básicas. Las unidades territoriales evaluadas comprendían desde zonas básicas de salud hasta CCAA. Resultados: El proceso se extendió del 4 de mayo al 21 de junio y se asoció a planes de refuerzo de las capacidades en las CCAA. La incidencia disminuyó de una mediana inicial de 7,4 por 100.000 en 7 días a 2,5 al final del proceso. La mediana de pruebas PCR aumentó del 53% al 89% de los casos sospechosos, y la capacidad total de 4,5 a 9,8 pruebas semanales por 1.000 habitantes; la positividad disminuyó del 3,5% al 1,8%. La mediana de casos con contactos trazados aumentó del 82% al 100%. Conclusión: La recogida y análisis sistemático de información y el diálogo interterritorial logaron un adecuado control del proceso. La situación epidemiológica mejoró, pero sobre todo, se aumentaron las capacidades, en todo el país y con criterios comunes, cuyo mantenimiento y refuerzo fue clave en olas sucesivas.

[Health impact of COVID pandemic. SESPAS Report 2022]. / El impacto de la pandemia de COVID-19 sobre la salud. Informe SESPAS 2022.

OBJECTIVE: The World Health Organization declared the global SARS-CoV-2 infection a pandemic on March 11, 2020. The objective of this paper is to present its impact in terms of physical and mental health 22 months later. METHOD: We have reviewed results from published meta-analysis and systematic reviews, and some individual articles on specific aspects of special interest. National information on infection comes for the Red Nacional de Vigilancia Epidemiológica (RENAVE). RESULTS: Up to the end of October, more than 250 million infections and 5 million deaths had been reported globally. In Spain, 4.7 million infections have been documented although the real figure might be above 7 million. The pandemic has reduced life expectancy, and its effects have been especially dramatic in people with comorbidities and the elderly. There is a worsening of mental health in the general population. It is foreseeable that some groups, such as health professionals, mostly women, and front-line workers, may have a greater risk of developing mental health pathologies. The pandemic and the control measures have had other undesirable consequences such as a decrease in healthcare utilization, an increase in sedentary lifestyle or an increase in gender violence. In addition to its immediate effect on morbidity and mortality, the control measures have damaged the overall health status of the global population. CONCLUSIONS: Longitudinal studies are necessary to determine the mid and long consequences of the pandemic and the control measures, and to identify and evaluate effective health interventions.

[Apropriateness of hospital admissions due to COVID-19 in the 2nd and 5th phase of the pandemic.] / Adecuación de ingresos hospitalarios por COVID-19 en la 2ª y 5ª fase de la pandemia.

OBJECTIVE: The increase in the demand for healthcare caused by COVID-19 implies a lower availability of health resources and influences the appropriateness of their use. Due to the variability of demand during the pandemic, the study aimed to compare the appropriateness of hospital admissions between the 2nd and 5th phases of the pandemic according to the criteria of the Hospital Emergency Service (CiHRyC). These results were compared with those obtained according to the Pneumonity Severity Index (FINE) and the Appropriateness Evaluation Protocol (AEP). As a secondary objective, the clinical and sociodemographic characteristics of the patients studied were described. METHODS: 80 patients hospitalized from the Emergency Department were randomly selected in two study periods (2nd and 5th pandemic phase) obtained from the registry of hospitalizations of the Preventive Medicine service of Hospital Ramon y Cajal. Prevalences of inappropriateness were estimated according to the CiHRyC, FINE and AEP and an analysis was performed using univariate logistic regression between epidemiological variables of both periods collected through the electronical medical records. RESULTS: Inappropriateness of admissions were 35% and 45% in the 2nd and 5th phase of the pandemic according with CiHRyC, 25% and 5/% according with FINE and 0% and 5% according with AEP. Median age was 71.4 and 50.0 years in 2nd and 5th phase (p=0.02). 72.5% and 17.5% of the patients in the 2nd and 5th phases had at least one risk factor for COVID-19 severe illness (p<0.01). CONCLUSIONS: The measurement tools used identified more inappropriately cases in the 5th phase of the pandemic than in the 2nd one. CiHRyC coincided with FINE and AEP in the result of their evaluation.

OBJETIVO: El aumento de la demanda asistencial hospitalaria producida por la COVID-19 supone una menor disponibilidad de recursos sanitarios e influye en la adecuación de su utilización. Debido a la variabilidad de la demanda durante la pandemia, el objetivo del estudio fue comparar la adecuación de los ingresos hospitalarios entre la 2ª y 5ª fase de la pandemia según los criterios del servicio de Urgencias del Hospital (CiHRyC). Se compararon estos resultados con los obtenidos según el Pneumonity Severity Index (FINE) y el Appropriateness Evaluation Protocol (AEP). Como objetivo secundario se describieron las características clínicas y sociodemográficas de los pacientes estudiados. METODOS: Se seleccionaron aleatoriamente 80 pacientes hospitalizados desde Urgencias en dos periodos de estudio (2ª y 5ª fase pandémica) obtenidos del registro de hospitalizaciones del servicio de Medicina Preventiva del Hospital Ramón y Cajal. Se estimaron las prevalencias de inadecuación según los CiHRyC, el FINE y el AEP para admisiones y se realizó un análisis mediante regresión logística univariante entre las variables epidemiológicas de ambos periodos recogidas mediante la Historia Clínica Electrónica (HCE). RESULTADOS: La inadecuación de la hospitalización fue del 35% y 45% en la 2ª y 5ª fase de la pandemia con los CiHRyC, del 25% y 57% con el FINE y del 0% y 5% con el AEP. La mediana de edad fue de 71,4 y 50 años en la 2ª y 5ª fase (p=0,02). El 72,5% y el 17,5% de los pacientes de la 2ª y 5ª fase tuvieron al menos un factor de riesgo de complicaciones de COVID-19 (p<0,01). CONCLUSIONES: Los instrumentos de medida empleados (CiHRyC, el FINE y el AEP) identificaron más casos inadecuadamente ingresados en la 5ª fase de la pandemia que en la 2ª, coincidiendo el CiHRyC con el FINE y el AEP en el resultado de su evaluación.

A population-based controlled experiment assessing the epidemiological impact of digital contact tracing.

While Digital contact tracing (DCT) has been argued to be a valuable complement to manual tracing in the containment of COVID-19, no empirical evidence of its effectiveness is available to date. Here, we report the results of a 4-week population-based controlled experiment that took place in La Gomera (Canary Islands, Spain) between June and July 2020, where we assessed the epidemiological impact of the Spanish DCT app Radar Covid. After a substantial communication campaign, we estimate that at least 33% of the population adopted the technology and further showed relatively high adherence and compliance as well as a quick turnaround time. The app detects about 6.3 close-contacts per primary simulated infection, a significant percentage being contacts with strangers, although the spontaneous follow-up rate of these notified cases is low. Overall, these results provide experimental evidence of the potential usefulness of DCT during an epidemic outbreak in a real population.

Association of the European lactase persistence variant (LCT-13910 C>T polymorphism) with obesity in the Canary Islands.

BACKGROUND: European lactose tolerance genotype (LCT -13910 C>T, rs4988234) has been positively associated to body mass indexes (BMI) in a meta-analysis of 31,720 individuals of northern and central European descent. A strong association of lactase persistence (LP) with BMI and obesity has also been traced in a Spanish Mediterranean population. The aim of this study was to analyze a potential association of LP compared to lactase non-persistence (LNP) with BMI in inhabitants of the Canary Islands of Spain using Mendelian randomization. METHODS: A representative, randomly sampled population of adults belonging to the Canary Islands Nutrition Survey (ENCA) in Spain, aged 18-75 years (n = 551), was genotyped for the LCT - 13910 C>T polymorphism. Milk consumption was assessed by a validated questionnaire. Anthropometric variables were directly measured. WHO classification of BMI was used. RESULTS: LP individuals were significantly more obese than LNP subjects (χ(2) = 10.59; p<0.005). LP showed in a multivariate linear regression analysis showed a positive association of LP with BMI compared to LNP, (ß = 0.96; 95% CI: 0.08-1.85, p = 0.033). In a multinomial logistic regression analysis normal range weight LP subjects showed an odds ratio for obesity of 2.41; 95%CI 1.39-418, (p = 0.002) compared to LNP. CONCLUSIONS: The T-13910 of the allele LCT-13910 C>T polymorphism is positively associated with BMI. LP increases significantly the risk to develop obesity in the studied population. The LCT-13910 C>T polymorphism stands proxy for the lifetime exposure pattern, milk intake, that may increase susceptibility to obesity and to obesity related pathologies.

The relationship between dioxin-like polychlorobiphenyls and IGF-I serum levels in healthy adults: evidence from a cross-sectional study.

OBJECTIVE: Insulin-like growth factor I (IGF-I) and dioxin-like polychlorobiphenyls (DL-PCBs) have been associated with the pathogenesis of several diseases like cancer, diabetes and growth disorders. Because it has been suggested that organohalogenated contaminants could influence IGF-I levels in adults, the potential relationship between DL-PCBs and IGF-I serum levels was studied in 456 healthy adults from a representative sample of the general population of the Canary Islands (Spain). DESIGN: Free circulating serum levels of IGF-I and IGFBP-3 were measured through an ELISA methodology, while the serum levels of the 12 DL-PCBs congeners (IUPAC numbers # 77, 81, 105, 114, 118, 123, 126, 156, 157, 167, 169, and 189) were measured by gas chromatography/mass spectrometry (GC-MS). RESULTS: DL-PCBs 156 and 167, Total DL-PCBs body burden (∑PCBs: sum over the 12 measured DL-PCBs), and Total toxic burden (in terms of toxic equivalence to dioxins: ∑TEQs) showed a trend of inverse association with IGF-I serum levels in the whole studied population. After adjusting for potential confounders, including gender, body mass index (BMI), age, and IGF-binding protein-3 (IGFBP-3), younger (18-45 years) women with lower BMI (<27 kg/m(2)) and detectable levels of DL-PCB-156 showed significantly lower IGF-I levels than those in the same age and BMI subgroup with non-detectable levels of DL-PCB-156 (p<0.001). Similarly, ∑PCBs and ∑TEQs showed a tendency to an inverse association with IGF-I levels in the same group of women (p=0.017 and p=0.019 respectively). CONCLUSIONS: These findings suggest that DL-PCBs could be involved in the regulation of the IGF-system in a way possibly influenced by gender, age and BMI. Although these results should be interpreted with caution, such circumstances could contribute to explain the development of diseases associated to the IGF system.

Polymorphisms of glutathione S-transferase µ and θ, MDR1 and VEGF genes as risk factors of bladder cancer: a case-control study.

OBJECTIVE: The present study was aimed at examining the local distribution of GSTM1, GSTT1, MDR1, and VEGF gene polymorphisms as possible risk factors contributing to the development of bladder cancer among the population from Canary Islands, Spain. MATERIALS AND METHODS: The genotypes were determined by PCR-based methods in a hospital-based case-control study consisting of 119 cases and 110 controls. The socio-demographic and clinicopathologic data were collected, including the smoking habits of the population covered in the study. RESULTS: The observed allelic frequencies were (%): GSTM1-GSTT1, (positive) 54 and (null) 46 in cases, and 65 and 35, respectively, in controls (P = 0.144); MDR1 C3435T, (C) 57 and (T) 43 in cases, and 54 and 46, respectively, in controls (P = 0.633); VEGF A2578C, (A) 40 and (C) 60 in cases, and 51 and 49, respectively, in controls (P = 0.221). Among Canary Islands subjects, GSTT1-null genotype appeared as a significant risk factor for bladder cancer (odds ratio (OR) 2.0; 95% confidence interval (CI), 1.0-3.7; P = 0.041), in multivariate analysis adjusted by age and smoking habits. No statistical changes in genotype distribution of GSTM1, MDR1 C3435T, and VEGF A2578C gene polymorphisms were observed between cases and controls. The distribution of the initial clinical stage, clinical grade, or recurrence status was not significantly different among the polymorphic variants in the case group (P = NS). CONCLUSIONS: Subjects with the GSTT1-null genotype might be at an increased risk of bladder cancer in Canary Islands, Spain. However, extensive studies are required for accurate confirmation of these results.

Finalización electiva versus manejo expectante en el control de la gestación prolongada: estudio prospectivo de 200 gestantes / Elective termination versus expectant management in prolonged pregnancy: a prospective study of 200 pregnant women

Objetivo. Comparar la finalización electiva de la gestación prolongada versus el manejo expectante, en gestaciones de bajo riesgo obstétrico. Material y método. Ensayo clínico controlado y aleatorizado entre actuaciones activas y expectantes, sobre una muestra de 200 mujeres con gestación prolongada de bajo riesgo obstétrico entre febrero de 2003 y junio de 2005 en el Hospital Universitario Materno-Infantil de Canarias. Resultados. El grupo estudio está formado por 200 pacientes - 102 del grupo activa y 98 del grupo expectante -. No se encontraron diferencias epidemiológicas entre ambos grupos. El parto no fue inducido en un porcentaje de gestantes significativamente superior en el grupo activa frente al grupo expectante (51% vs 35,7%, p=0,02; OR 0,53 [CI 95% 0,3-0,94]), es decir, el número de inducciones es significativamente superior en el grupo de manejo expectante. Una tasa significativamente menor de gestantes del grupo activa presentó líquido amniótico meconial durante la dilatación (15,7% vs 28,6% p=0,02; OR 0,47 [IC 95% 0,23-0,93]). No existen diferencias significativas con relación al tipo de parto, no obstante el porcentaje de intervención cesárea fue marcadamente inferior en el grupo activa frente al grupo expectante ([12,7% vs 18,4%, p=0,3; OR 0,65 [IC 95% 0.3-1.41]). Los resultados perinatales no muestran diferencias significativas entre ambos grupos. Conclusiones. La finalización electiva en el semana 42, en gestaciones de bajo riesgo obstétrico con condiciones cervicales desfavorables, parece reducir la tasa de cesáreas sin comprometer los resultados perinatales (AU)

Objective. To compare elective termination versus expectant management in low-risk prolonged pregnancy. Material and method. We performed a controlled randomized clinical trial comparing the results of active and expectant approaches in the management of low-risk prolonged pregnancy in a sample of 200 women between February 2003 and June 2005 at the Maternity Ward of the Canary Islands University Hospital. Results. The study group consisted of 200 patients. There were 102 in the active management group and 98 in the expectant management group. No between-group epidemiologic differences were found. Labor was not induced in a significantly higher proportion of patients in the active than in the expectant group [51% vs 35.7%, p=0.02; OR 0.53 (95% CI 0.3-0.94)] i.e. the induction rate was significantly higher in the expectant group. The proportion of patients with meconium-stained amniotic fluid during labor was significantly lower in the active management group [15.7% vs 28.6% p=0.02; OR 0.47 (95% CI 0.23-0.93)]. No significant differences were found in the type of delivery, although the proportion of cesarean sections was noticeably lower in the active management than in the expectant management group [(12.7% vs 18.4%, p=0.3; OR 0.65 (95% CI 0.3-1.41)]. No significant differences were found in perinatal outcomes between the two groups. Conclusions. Elective termination of low-risk pregnancies with unfavorable cervical findings at week 42 seems to reduce the rate of cesarean section without impairing perinatal outcome (AU)

Screening for tuberculosis infection in spanish healthcare workers: Comparison of the QuantiFERON-TB gold in-tube test with the tuberculin skin test.

OBJECTIVE: The risk of latent tuberculosis (LTBI) in healthcare workers (HCWs) is high. Until recently, the tuberculin skin test (TST) was the only diagnostic test available for Mycobacterium tuberculosis infection. A new enzyme-linked immunosorbent assay test, the QuantiFERON-TB Gold (QFT-G) test, was recommended by the US Centers for Disease Control and Prevention as an alternative test for the diagnosis of LTBI in HCWs. The purpose of our study was to compare the TST and the QFT-G test in Spanish HCWs in order to improve procedures for the detection of LTBI. METHODS: A cross-sectional study with blinded comparison of TST and QFT-G test results was carried out among 134 HCWs at an 800-bed Spanish university hospital. The level of interferon-gamma production stimulated by the QFT-G test was measured. A concentration of at least 0.35 IU/mL was considered a positive result. An induration of at least 5 mm in non-BCG-vaccinated or at least 15 mm in BCG-vaccinated HCWs for the TST was considered positive. RESULTS: Of the 134 HCWs included (mean age, 33.4 years; 101 [75.4%] women; 47 [35.1%] BCG vaccinated), the LTBI prevalence diagnosed with any test was 11.2% (95% confidence interval, 6.6%-18.1%), with the TST was 8.96%, and with the QFT-G test was 5.97% (nonsignificant differences). The QFT-G test value was higher in subjects with TST induration of at least 15 mm than in subjects with TST induration of less than 15 mm (P < .001). Overall agreement between the results of the two tests was found in 94% of HCWs (kappa = 0.56), but agreement was only 59% in HCWs who had a positive result for both tests. Disagreement was present in the results found for 5% of HCWs. CONCLUSIONS: Few studies have compared both tests in populations with high M. tuberculosis exposure but low BCG vaccination prevalence. Agreement between both tests is high, especially among negative results. Studies are needed to clarify the reasons for disagreement and to establish the best TST and QFT-G test cutoff point.

Dairy products and health: a review of the epidemiological evidence.

Evidence-based nutrition is essential to move forward in the science of community nutrition. The present study is a review of the epidemiological evidence of dairy products and health. There is an inverse association between the intake of dairy products and hypertension, stroke and colorectal cancer. There is no evidence of an association between the consumption of dairy products and breast cancer. There is some evidence linking high-fat dairy products and an incremental risk of prostate cancer and weak evidence of the protective capacity of dairy products on bone health. More prospective studies should be developed in order to establish better evidence of the relationship between dairy products and health. Due to the importance of dairy products in public health nutrition, quantitative recommendations should be established in the light of the scientific evidence.

Efectos adversos relacionados con la asistencia sanitaria en ginecología y obstetricia: una revisión crítica / Adverse events caused by medical care in obstetrics and gynecology: a review

Objetivo: Identificar trabajos que analizan efectos adversos (EA) ligados a la asistencia sanitaria en ginecología y obstetricia. Material y método: Revisión de la literatura científica en MEDLINE (1960-actualidad). Selección de estudios: abstract disponible; idiomas inglés/castellano/francés; artículo que aporta datos sobre frecuencia, distribución o características de los EA que afectan a población ginecológica u obstétrica. Resultados: Fueron seleccionados 57 estudios. Se identificó un incidente (definido como "acontecimiento que no es esperable dentro de la rutina de cuidados del paciente") en el 39,2% de los partos. Hay 1,4 errores de medicación por cada 1.000 estancias en obstetricia (que no ocasionan daño) y 3,54 errores de medicación por cada 1.000 órdenes médicas en obstetricia y ginecología. La tasa de infección de la herida quirúrgica después de una cesárea oscila entre el 1,5 y el 11,2%. Respecto a las intervenciones quirúrgicas en ginecología, el porcentaje de complicaciones mayores (lesiones en tracto urinario, digestivo o vasos) oscila entre el 0,14 y el 0,4%. La morbilidad infecciosa está en el 2,2-22%, dependiendo de la vía de abordaje (menor en las laparoscopias). La enfermedad tromboembólica tras cirugía ginecológica tiene una incidencia del 0,2-0,5%. Conclusiones: Existe una carencia de estudios específicos que analicen la incidencia de EA en ginecología y obstetricia. En el 40% de los partos ocurre un incidente. En ginecología el EA más frecuente es la infección posquirúrgica. Los estudios muestran que el análisis detallado de los EA puede ayudar a la detección de oportunidades de mejora, realización de acciones correctoras y, en consecuencia, a la disminución de EA posteriores

Objective: To identify studies that analyze adverse events (AE) related to medical care in gynecology and obstetrics. Material and method: Review of the scientific literature in MEDLINE (1960-present). Selection of studies: abstract available; languages English/Spanish/French; articles that provided data on the frequency, distribution or characteristics of AE in gynecological or obstetric patients. Results: Fifty-seven studies were selected. In 39.2% of deliveries an incident (defined as "occurrences that are not consistent with routine hospital operation or patient care") was identified. There were 1.4 medication errors for every 1,000 hospital stays in obstetrics and 3.54 medication errors for every 1,000 medical orders in obstetrics and gynecology. The surgical wound infection rate after caesarean section oscillated from 1.5-11.2%. The rate of major complications (injuries to the urinary or digestive tracts or blood vessels) in gynecological surgery ranged from 0.14-0.4%. The rate of infectious complications oscillated from 2.2-22%, depending on the type of approach (lower in laparoscopy). The incidence of thromboembolic disease after gynecological surgery was 0.2-0.5%. Conclusions: There is a scarcity of studies that specifically analyze the incidence of AE in gynecology and obstetrics. Incidents occur in 40% of deliveries. In gynecology the most frequent AE is postoperative infection. Detailed analysis of AE could identify areas for improvement and consequently diminish the incidence of AE

[Prevalence of the metabolic syndrome in the population of Canary Islands, Spain]. / Prevalencia del síndrome metabólico en la población de la Comunidad Canaria.

BACKGROUND AND OBJECTIVE: The program for the detection of high blood cholesterol in adults (ATP III) has recently published diagnostic criteria for the metabolic syndrome. Its prevalence in the Canarian population is reported here. SUBJECTS AND METHOD: 578 adults, who participated in the Nutritional Survey of the Canary Islands (ENCA 1997-1998) were selected. Metabolic syndrome was fined as the presence of 3 or more criteria. RESULTS: Three out of every four individuals fulfilled at least one of the criteria. In men, hypertriglyceridemia, hypertension and hyperglycemia predominated. In women, abdominal obesity and low HDL-cholesterol were more common. The global prevalence of the syndrome was 24.4% (95%CI: 19.6-29.8), increasing with age and decreasing with the educational level. CONCLUSIONS: The prevalence of the metabolic syndrome among adults from the Nutritional Survey of the Canary Islands is high and similar to that observed in the USA (21.8%).

Prevalencia del síndrome metabólico en la población de la Comunidad Canaria / Prevalence of the metabolic syndrome in the population of Canary Islands, Spain

FUNDAMENTO Y OBJETIVO: Recientemente el programa para la detección de la hipercolesterolemia en adultos de EE.UU. (ATP III) ha publicado los criterios diagnósticos del síndrome metabólico. Se presenta su prevalencia en la población canaria. SUJETOS Y MÉTODO: Se seleccionó a 578 adultos que participaron en la Encuesta Nutricional de Canarias (ENCA 1997-1998). El síndrome metabólico se define como la presencia de tres o más criterios. RESULTADOS: Tres de cada 4 individuos cumplían algún criterio. En los varones predominó la hipertrigliceridemia, hipertensión e hiperglucemia, y en las mujeres, la obesidad abdominal y una concentración baja de colesterol HDL. La prevalencia global del síndrome fue del 24,4 per cent (intervalo de confianza [IC] del 95 per cent, 19,629,8), aumentando con la edad y disminuyendo con el nivel de estudios. CONCLUSIONES: La prevalencia del síndrome metabólico en la ENCA es alta, similar a la encontrada en EE.UU. (21,8 per cent). (AU)

Ganancia de peso a lo largo de la vida adulta / Weight gain along adult life

FUNDAMENTO: La obesidad es un problema grave de salud de difícil tratamiento y prevención. Estimar la ganancia de peso corporal a lo largo de la vida adulta puede ayudar a prevenir la obesidad en adultos. SUJETOS Y MÉTODO: En este estudio transversal se valoró la ganancia de peso autorreferida desde los 20 años de edad en una muestra de 1.286 adultos de ambos sexos. RESULTADOS: El incremento medio de peso estimado por decenio fue de 4,5 kg entre los 20 y 49 años de edad (ambos sexos), y de 1 kg en varones y 2 kg en mujeres entre los 50 y 69 años. A partir de los 70 años el peso disminuyó. CONCLUSIÓN: La ganancia de peso en adultos es continuada desde los 20 años hasta la sexta década de la vida en uno y otro sexo, aunque se prolonga más en mujeres (AU)
