Has COVID-19 Affected DTP3 Vaccination in the Americas?

BACKGROUND: In the Americas, deaths by diseases avoidable with vaccines are a significant contributor to child mortality. An essential means of reducing this is through broad vaccine coverage. The COVID-19 pandemic has posed a potential disruption to vaccine coverage due to its effects on the healthcare system. OBJECTIVES: this study aims to evaluate the impact of the COVID-19 pandemic on DTP3 vaccination coverage in the Americas, investigating trends from 2012 to 2022 to identify significant changes, regional disparities, and the overall effect of the pandemic on progress towards global immunization targets. METHODS: This study used the coverage data for the third dose of the diphtheria, tetanus, and pertussis vaccine (DTP3) pulled from UNICEF databases spanning 2012 to 2022. We conducted a Joinpoint regression to identify points of significant trend changes. The annual percentage change (APC) and 95% confidence intervals (95% CIs) were calculated for America and its regions. We also used segmented regression analysis. Using the Chi-square test, we compared DTP3 vaccination coverage for each country between 2019 and 2022. RESULTS: Overall, America saw a decrease in vaccine coverage during this period, with an APC of -1.4 (95% CI -1.8; -1.0). This trend varied across regions. In North America, the decrease was negligible (-0.1% APC). South America showed the steepest decrease, with an APC of -2.5%. Central America also declined, with an APC of -1.3%. Our findings suggest a concerning trend of declining DTP-vaccination rates in the Americas, exacerbated in certain regions, in the wake of the COVID-19 pandemic. The absolute decrease in vaccine coverage in the Americas was -4% between 2019 and 2022, with the most important drop being in Central America (-7%). However, six countries reported increased vaccination rates post-COVID-19, led by Brazil, with a 7% increase. Conversely, twenty-two countries registered a decline in DTP3 vaccine coverage, with the average decrease being -7.37%. This decline poses an important challenge to achieving the WHO's target of 90% coverage for the third dose of DTP by 2030, as evidenced by the reduction in the number of countries meeting this target from 2019 to 2022. CONCLUSIONS: The COVID-19 pandemic has impacted vaccine coverage in America, leading to a decrease, especially across Central America.

Evaluating the Efficacy of ChatGPT in Navigating the Spanish Medical Residency Entrance Examination (MIR): Promising Horizons for AI in Clinical Medicine.

The rapid progress in artificial intelligence, machine learning, and natural language processing has led to increasingly sophisticated large language models (LLMs) for use in healthcare. This study assesses the performance of two LLMs, the GPT-3.5 and GPT-4 models, in passing the MIR medical examination for access to medical specialist training in Spain. Our objectives included gauging the model's overall performance, analyzing discrepancies across different medical specialties, discerning between theoretical and practical questions, estimating error proportions, and assessing the hypothetical severity of errors committed by a physician. MATERIAL AND METHODS: We studied the 2022 Spanish MIR examination results after excluding those questions requiring image evaluations or having acknowledged errors. The remaining 182 questions were presented to the LLM GPT-4 and GPT-3.5 in Spanish and English. Logistic regression models analyzed the relationships between question length, sequence, and performance. We also analyzed the 23 questions with images, using GPT-4's new image analysis capability. RESULTS: GPT-4 outperformed GPT-3.5, scoring 86.81% in Spanish (p < 0.001). English translations had a slightly enhanced performance. GPT-4 scored 26.1% of the questions with images in English. The results were worse when the questions were in Spanish, 13.0%, although the differences were not statistically significant (p = 0.250). Among medical specialties, GPT-4 achieved a 100% correct response rate in several areas, and the Pharmacology, Critical Care, and Infectious Diseases specialties showed lower performance. The error analysis revealed that while a 13.2% error rate existed, the gravest categories, such as "error requiring intervention to sustain life" and "error resulting in death", had a 0% rate. CONCLUSIONS: GPT-4 performs robustly on the Spanish MIR examination, with varying capabilities to discriminate knowledge across specialties. While the model's high success rate is commendable, understanding the error severity is critical, especially when considering AI's potential role in real-world medical practice and its implications for patient safety.

Prevalence and time trends of symptoms of allergic rhinitis and rhinoconjunctivitis in Spanish children: Global Asthma Network (GAN) study.

INTRODUCTION: The time trends of the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy previously described in the ISAAC (International Study of Asthma and Allergies in Childhood) in 2002 are unknown; or if the geographical or age differences in Spain persist. OBJECTIVE: To describe the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy in different Spanish geographical areas and compare them with those of the ISAAC. METHODS: Cross-sectional study of the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy, carried out in 2016-2019 on 19943 adolescents aged 13-14 years and 17215 schoolchildren aged 6-7 years from six Spanish areas (Cartagena, Bilbao, Cantabria, La Coruña, Pamplona, and Salamanca), through a questionnaire based on the Global Asthma Network (GAN) protocol. RESULTS: The prevalences of recent rhinitis and rhinoconjunctivitis (last 12 months), and nasal allergy/hay fever were 35.1%, 17.6%, and 14.6% in the adolescents and 20%, 8.5%, and 8.9% in the schoolchildren, respectively, with rhinoconjunctivitis in adolescents varying from 20.9% in Bilbao to 13.4% in Cartagena; and in schoolchildren, from 9.8% in La Coruña to 6.4% in Pamplona. These prevalences of rhinoconjunctivitis and nasal allergy in adolescents were higher than those described in the ISAAC (16.3% and 13%) and similar in schoolchildren to the ISAAC (9% and 9.4%). CONCLUSIONS: There has been a stabilisation of rhinitis, rhinoconjunctivitis and nasal allergy in schoolchildren that slows the previous upward trend of ISAAC; and a slight non-significant increase in rhinoconjunctivitis and nasal allergy in adolescents. The variability found in adolescents would require local research to be better understood.

Trends, Projections, and Regional Disparities of Maternal Mortality in Africa (1990-2030): An ARIMA Forecasting Approach.

With the United Nations Sustainable Development Goals (SDG) (2015-2030) focused on the reduction in maternal mortality, monitoring and forecasting maternal mortality rates (MMRs) in regions like Africa is crucial for health strategy planning by policymakers, international organizations, and NGOs. We collected maternal mortality rates per 100,000 births from the World Bank database between 1990 and 2015. Joinpoint regression was applied to assess trends, and the autoregressive integrated moving average (ARIMA) model was used on 1990-2015 data to forecast the MMRs for the next 15 years. We also used the Holt method and the machine-learning Prophet Forecasting Model. The study found a decline in MMRs in Africa with an average annual percentage change (APC) of -2.6% (95% CI -2.7; -2.5). North Africa reported the lowest MMR, while East Africa experienced the sharpest decline. The region-specific ARIMA models predict that the maternal mortality rate (MMR) in 2030 will vary across regions, ranging from 161 deaths per 100,000 births in North Africa to 302 deaths per 100,000 births in Central Africa, averaging 182 per 100,000 births for the continent. Despite the observed decreasing trend in maternal mortality rate (MMR), the MMR in Africa remains relatively high. The results indicate that MMR in Africa will continue to decrease by 2030. However, no region of Africa will likely reach the SDG target.

Effects of Nutrition Interventions on Athletic Performance in Soccer Players: A Systematic Review.

BACKGROUND: More than 270 million participants and 128,893 professional players play soccer. Although UEFA recommendations for nutrition in elite football exist, implementing these guidelines among professional and semiprofessional soccer players remains suboptimal, emphasizing the need for targeted and individualized nutritional strategies to improve adherence to established recommendations. METHODS: We conducted a comprehensive search in PubMed, Scopus, Web of Science, and clinical trial registers. Inclusion criteria focused on professional or semiprofessional soccer players, nutrition or diet interventions, performance improvement outcomes, and randomized clinical trial study types. We assessed quality using the Risk of Bias 2 (RoB 2) tool. We identified 16 eligible articles involving 310 participants. No nutritional interventions during the recovery period effectively improved recovery. However, several performance-based interventions showed positive effects, such as tart cherry supplementation, raw pistachio nut kernels, bicarbonate and mineral ingestion, creatine supplementation, betaine consumption, symbiotic supplements, and a high-carbohydrate diet. These interventions influenced various aspects of soccer performance, including endurance, speed, agility, strength, power, explosiveness, and anaerobic capacity. CONCLUSIONS: Specific strategies, such as solutions with bicarbonate and minerals, high carbohydrate diets, and supplements like creatine, betaine, and tart cherry, can enhance the performance of professional soccer players. These targeted nutritional interventions may help optimize performance and provide the competitive edge required in professional soccer. We did not find any dietary interventions that could enhance recovery.

COVID-19 Impact on DTP Vaccination Trends in Africa: A Joinpoint Regression Analysis.

BACKGROUND: Deaths due to vaccine-preventable diseases are one of the leading causes of death among African children. Vaccine coverage is an essential measure to decrease infant mortality. The COVID-19 pandemic has affected the healthcare system and may have disrupted vaccine coverage. METHODS: DTP third doses (DTP3) Vaccine Coverage was extracted from UNICEF databases from 2012 to 2021 (the last available date). Joinpoint regression was performed to detect the point where the trend changed. The annual percentage change (APC) with 95% confidence intervals (95% CI) was calculated for Africa and the regions. We compared DTP3 vaccination coverage in 2019-2021 in each country using the Chi-square test. RESULT: During the whole period, the vaccine coverage in Africa increased with an Annual Percent change of 1.2% (IC 95% 0.9-1.5): We detected one joinpoint in 2019. In 2019-2021, there was a decrease in DTP3 coverage with an APC of -3.5 (95% -6.0; -0,9). (p < 0.001). Vaccination rates decreased in many regions of Sub-Saharan Africa, especially in Eastern and Southern Africa. There were 26 countries (Angola, Cabo Verde, Comoros, Congo, Côte d'Ivoire, Democratic Republic of the Congo, Djibouti, Ethiopia, Eswatini, The Gambia, Guinea-Bissau, Liberia, Madagascar, Malawi, Mauritania, Mauritius, Mozambique, Rwanda, Senegal, Seychelles, Sierra Leone, Sudan, Tanzania, Togo, Tunisia, Uganda, and Zimbabwe) where the vaccine coverage during the two years decreased. There were 10 countries (Angola, Cabo Verde, Comoros, Democratic Republic of the Congo, Eswatini, The Gambia, Mozambique, Rwanda, Senegal, and Sudan) where the joinpoint regression detected a change in the trend. CONCLUSIONS: COVID-19 has disrupted vaccine coverage, decreasing it all over Africa.

Maternal Mortality in Africa: Regional Trends (2000-2017).

BACKGROUND: United Nations Sustainable Development Goals state that by 2030, the global maternal mortality rate (MMR) should be lower than 70 per 100,000 live births. MMR is still one of Africa's leading causes of death among women. The leading causes of maternal mortality in Africa are hemorrhage and eclampsia. This research aims to study regional trends in maternal mortality (MM) in Africa. METHODS: We extracted data for maternal mortality rates per 100,000 births from the United Nations Children's Fund (UNICEF) databank from 2000 to 2017, 2017 being the last date available. Joinpoint regression was used to study the trends and estimate the annual percent change (APC). RESULTS: Maternal mortality has decreased in Africa over the study period by an average APC of -3.0% (95% CI -2.9; -3,2%). All regions showed significant downward trends, with the greatest decreases in the South. Only the North African region is close to the United Nations' sustainable development goals for Maternal mortality. The remaining Sub-Saharan African regions are still far from achieving the goals. CONCLUSIONS: Maternal mortality has decreased in Africa, especially in the South African region. The only region close to the United Nations' target is the North African region. The remaining Sub-Saharan African regions are still far from achieving the goals. The West African region needs more extraordinary efforts to achieve the goals of the United Nations. Policies should ensure that all pregnant women have antenatal visits and give birth in a health facility staffed by specialized personnel.

Prevalencia y evolución temporal de síntomas de asma en España. Estudio Global Asthma Network (GAN) / Prevalence and temporal evolution of asthma symptoms in Spain. Global Asthma Network (GAN) study

Introducción: Se desconoce la evolución temporal de la prevalencia de asma descrita en el ISAAC (International Study of Asthma and Allergies in Childhood) en 2002 o si las diferencias geográficas o por edades se mantienen en España. Objetivo: Describir la prevalencia de los síntomas de asma en distintas áreas geográficas españolas y compararla con la de aquellos centros que participaron en el ISAAC. Métodos: Estudio transversal de prevalencia de asma, realizado en 2016-2019 a 19.943 adolescentes de 13-14 años y 17.215 escolares de 6-7 años de seis áreas geográficas españolas (Cartagena, Bilbao, Cantabria, La Coruña, Pamplona y Salamanca). Los síntomas de asma se recogieron mediante un cuestionario escrito y videocuestionario según el protocolo Global Asthma Network (GAN). Resultados: La prevalencia de sibilancias recientes (últimos 12 meses) fue del 15,3% a los 13-14 años y del 10,4% a los 6-7 años, con variaciones en los adolescentes, desde un 19% en Bilbao, hasta un 10,2% en Cartagena; y en los escolares, desde un 11,7% en Cartagena, hasta un 7% en Pamplona. Estas prevalencias fueron superiores a las del ISAAC (10,6% en adolescentes y 9,9% en los escolares). Un 21,3% de adolescentes y un 12,4% de los escolares refirieron asma alguna vez. Conclusiones: Existe una alta prevalencia de síntomas asmáticos con un incremento en los adolescentes y una estabilización en los escolares españoles con respecto al ISAAC. No se aprecian tan claramente variaciones geográficas en la prevalencia de asma, pero las áreas que tenían prevalencias elevadas mantienen cifras altas. (AU)

Asthma symptoms were collected using a written questionnaire and video questionnaire according to the Global Asthma Network (GAN) protocol. Results: The prevalence of recent wheezing (last 12 months) was 15.3% at 13–14 years and 10.4% at 6–7 years, with variations in adolescents, from 19% in Bilbao to 10.2% in Cartagena; and in schoolchildren, from 11.7% in Cartagena to 7% in Pamplona. These prevalences were higher than those of the ISAAC (10.6% in adolescents and 9.9% in schoolchildren). About 21.3% of adolescents and 12.4% of schoolchildren reported asthma at some time. Conclusions: There is a high prevalence of asthmatic symptoms with an increase in adolescents and a stabilization in Spanish schoolchildren with respect to the ISAAC. Geographical variations in asthma prevalence are not so clearly appreciated, but areas with high prevalences maintain high numbers. (AU)

Trends in Mortality from Stroke in Latin America and the Caribbean, 1979-2015.

Background: Stroke is the second largest single cause of death and disability in Latin America and the Caribbean (LAC). There have been large overall declines in stroke mortality rates in most LAC countries in recent decades. Objective: To analyze trends in mortality caused by stroke in LAC countries in the period 1979-2015. Methods: We extracted data for age-standardized stroke mortality rates per 100,000 in LAC for the period 1979-2015 from the World Health Organization Mortality Database. Joinpoint regression was used to analyze the trends and compute the annual percent change (APC) in LAC as a whole and by country. Analyses were conducted by gender, region and World Bank income classification. Results: Mortality from stroke has decreased in LAC over the study period by an average APC of -1.9%. Most countries showed significant downward trends, with the sharpest decreases in Chile, Colombia and Uruguay. We recorded statistically significant decreases of -1.4% and -2.4% in mortality rates in men and women, respectively, in the whole LAC. Southern and high-income countries showed the steepest decreases. Conclusions: Stroke mortality has decreased in LAC, in both sexes, especially in southern and high-income countries. Our results could serve as a reference for the development of primary prevention and acute management of stroke policies focused on countries with higher mortality.

Schizophrenia and Hospital Admissions for Cardiovascular Events in a Large Population: The APNA Study.

(1) Background: Patients with schizophrenia have higher mortality, with cardiovascular diseases being the first cause of mortality. This study aims to estimate the excess risk of hospital admission for cardiovascular events in schizophrenic patients, adjusting for comorbidity and risk factors. (2) Methods: The APNA study is a dynamic prospective cohort of all residents in Navarra, Spain. A total of 505,889 people over 18 years old were followed for five years. The endpoint was hospital admissions for a cardiovascular event. Direct Acyclic Graphs (DAG) and Cox regression were used. (3) Results: Schizophrenic patients had a Hazard Ratio (HR) of 1.414 (95% CI 1.031-1.938) of hospital admission for a cardiovascular event after adjusting for age, sex, hypertension, type 2 diabetes, dyslipidemia, smoking, low income, obesity, antecedents of cardiovascular disease, and smoking. In non-adherent to antipsychotic treatment schizophrenia patients, the HR was 2.232 (95% CI 1.267-3.933). (4) Conclusions: Patients with schizophrenia have a higher risk of hospital admission for cardiovascular events than persons with the same risk factors without schizophrenia. Primary care nursing interventions should monitor these patients and reduce cardiovascular risk factors.

Variability in the Control of Type 2 Diabetes in Primary Care and Its Association with Hospital Admissions for Vascular Events. The APNA Study.

Type 2 diabetes (T2D) is associated with increased cardiovascular morbidity, mortality, and hospital admissions. This study aimed to analyze how the differences in delivered care (variability of glycosylated hemoglobin (HbA1c) achieved targets) affect hospital admissions for cardiovascular events (CVEs) in T2D patients. Methods: We analyzed the electronic records in primary care health centers at Navarra (Spain) and hospital admission for CVEs. We followed 26,435 patients with T2D from 2012 to 2016. The variables collected were age, sex, health center, general practitioner practice (GPP), and income. The clinical variables were diagnosis of T2D, weight, height, body mass index (BMI), blood pressure (BP), HbA1c, low-density lipoprotein cholesterol (LDL-C), smoking, and antecedents of CVEs. We calculated, in each GPP practice, the proportion of patients with HbA1c ≥ 9. A non-hierarchical K-means cluster analysis classified GPPs into two clusters according to the level of compliance with HbA1C ≥ 9% control indicators. We used logistic and Cox regressions. Results: T2D patients had a higher probability of admission for CVEs when they belonged to a GPP in the worst control cluster of HbA1C ≥ 9% (HR = 1.151; 95% CI, 1.032-1.284).

Do physical activity and sedentary time mediate the association of the perceived environment with BMI? The IPEN adult study.

The study's main aim was to examine whether adults' accelerometer-based physical activity and sedentary time mediated the associations of neighbourhood physical environmental perceptions with body mass index (BMI) and weight status across 10 high- and middle-income countries. Data from the IPEN Adult study, an observational multi-country study (n = 5712) were used. Results showed that sedentary time was a non-significant or inconsistent mediator in all models. MVPA mediated the associations of street connectivity, land use mix-diversity, infrastructure/safety for walking and aesthetics with BMI in single models. In the multiple model, MVPA only fully mediated the relation between land use mix-diversity and BMI. This finding was replicated in the models with weight status as outcome. MVPA partially mediated associations of composite environmental variables with weight status. So, although MVPA mediated some associations, future comprehensive studies are needed to determine other mechanisms that could explain the relation between the physical environment and weight outcomes. Food intake, food accessibility and the home environment may be important variables to consider. Based on the consistency of results across study sites, global advocacy for policies supporting more walkable neighbourhoods should seek to optimize land-use-mix when designing and re-designing cities or towns.

Modificación de la actividad física durante los tres primeros años de universidad / Changes in the physical activity of university students during the first three years of university

Introducción: la inactividad física constituye el cuarto factor de riesgo más importante de mortalidad en todo el mundo y los estudiantes universitarios presentan en un alto nivel este factor de riesgo. Objetivos: determinar la modificación de la actividad física de los estudiantes universitarios en Navarra durante los tres primeros años de universidad. Métodos: estudio observacional prospectivo de una cohorte de universitarios que participaron en el estudio en primer curso y dos años después, en tercer curso. Las cohortes fueron constituidas por 454 estudiantes que respondieron a un cuestionario de autocumplimentación voluntario y anónimo con variables sociodemográficas y relacionadas con la actividad física. Los datos se analizaron con el SPSS v21.0. Resultados: un 67,4% (n = 306) fueron mujeres y un 32,6% (n = 148) fueron hombres. El 61,6% de los estudiantes de primer curso realizaban más de 150 minutos a la semana de actividad física y se incrementó el porcentaje de estudiantes activos físicamente en un 2,7%. Entre quienes realizaban actividad física mínimo tres veces a la semana se observó un incremento del 6,1%, hasta alcanzar el 30,5% de estudiantes. Conclusiones: el periodo universitario no desempeña un papel significativo en la promoción de la actividad física, ya que se observan modificaciones mínimas en su práctica. A futuro, convendría plantearse los motivos que dificultan la actividad física y diseñar programas según las recomendaciones actuales

Introduction: physical inactivity is the fourth most important risk factor for mortality worldwide and university students present this risk factor at a high level. Objective: to determine the changes in the physical activity of university students in Navarra during the first three years of college. Methods: prospective observational study of a cohort of university students. They participated in the first year, and two years later in the third year. The cohorts were comprised of 454 students who answered a voluntary and anonymous self-completion questionnaire with sociodemographic and physical activity related variables. Data were analyzed with SPSS v21.0. Results: of the participants, 67.4% (n = 306) were women and 32.6% (n = 148) were men. In the first year, 61.6% of students performed more than 150 minutes of physical activity per week. This percentage increased by 2.7%. The frequency of physical activity at least three times a week increased 6.1%, reaching 30.5% of students. Conclusions: university does not play a significant role in the promotion of physical activity, finding minimal modifications. In the future, it would be convenient to consider the reasons that hinder physical activity and design programs according to current recommendations

Mortalidad infantil en la Unión Europea: análisis de tendencias en el período 1994-2015 / Infant mortality in the European Union: A time trend analysis of the 1994-2015 period

Introducción: La mortalidad infantil es un indicador de la salud infantil y una variable explicativa del desarrollo socioeconómico. Nuestro objetivo fue examinar los cambios y tendencias de la mortalidad infantil en la Unión Europea (UE) y sus 28 países miembros en el período 1994-2015. Métodos: Se recopilaron datos de muertes de niños menores de un año entre 1994 y 2015 de la base de datos Eurostat. Estudiamos las tendencias en la UE, por países y regiones, utilizando el análisis de regresión joinpoint. Se condujeron análisis adicionales para estudiar las tendencias de mortalidad neonatal y neonatal precoz. Resultados: La mortalidad infantil en la UE ha disminuido significativamente de 8,3 a 3,6 por 1.000 (porcentaje de cambio anual = -3,8%, intervalos de confianza del 95% -4,1; -3,6). Las tasas de mortalidad más altas se registraron en Rumanía y Bulgaria, y las tasas más bajas en países escandinavos (Finlandia, Suecia). Se encontraron tendencias descendentes significativas en los países de la UE, más pronunciadas en los países bálticos exsoviéticos y países de Europa oriental, mientras que los países de Europa occidental mostraron los descensos menos pronunciados. La mortalidad infantil ha aumentado significativamente en Grecia en los últimos años, mientras que en el Reino Unido e Irlanda las tasas se han estabilizado. Conclusiones: La mortalidad infantil ha disminuido en la UE y sus países en las últimas décadas, más pronunciadamente en los países de Europa oriental y los países bálticos exsoviéticos, mientras que en varios países de Europa occidental las tasas aumentaron o se han estabilizado en los últimos años

Background: Infant mortality is an indicator of child health, and an explanatory variable to reflect the socioeconomic development of a country. We aimed to examine the changes and trends of infant mortality in the European Union (EU) and its 28 member states in the 1994-2015 period. Methods: We extracted data of deaths in children aged less than one year between 1994 and 2015 from the Eurostat database. We analysed secular variation in the EU overall, by country and by geographical region using joinpoint regression analysis. We conducted additional analyses to examine neonatal and early neonatal mortality trends. Results: Infant mortality in the EU has declined significantly from 8,3 to 3,6 per 1,000 live births (annual percent change = -3,8%; 95% confidence interval, -4,1 to -3,6). Among EU countries, we found the highest mortality rates throughout the study period in Romania and Bulgaria, and the lowest rates in Scandinavian countries (Finland, Sweden). There were significant decreasing trends in every country of the EU, which were most pronounced in former Soviet Baltic states and Eastern European countries, and least pronounced in Western European countries. Mortality rates have increased significantly in Greece in the last years, and plateaued in the United Kingdom and Ireland. Conclusions: Our findings, which are based on official data, provide consistent evidence that infant mortality has declined steadily in the EU and its member states in the past decades, most markedly in Eastern European countries and former Soviet Baltic states. However, rates have risen or levelled off in some western countries in the past few years

Entre quienes realizaban actividad física mínimo tres veces a la semana se observó un incremento del 6,1%, hasta alcanzar el 30,5% de estudiantes. Conclusiones: el periodo universitario no desempeña un papel significativo en la promoción de la actividad física, ya que se observan modificaciones mínimas en su práctica. A futuro, convendría plantearse los motivos que dificultan la actividad física y diseñar programas según las recomendaciones actuales.

[Infant mortality in the European Union: A time trend analysis of the 1994-2015 period]. / Mortalidad infantil en la Unión Europea: análisis de tendencias en el período 1994-2015.

BACKGROUND: Infant mortality is an indicator of child health, and an explanatory variable to reflect the socioeconomic development of a country. We aimed to examine the changes and trends of infant mortality in the European Union (EU) and its 28 member states in the 1994-2015 period. METHODS: We extracted data of deaths in children aged less than one year between 1994 and 2015 from the Eurostat database. We analysed secular variation in the EU overall, by country and by geographical region using joinpoint regression analysis. We conducted additional analyses to examine neonatal and early neonatal mortality trends. RESULTS: Infant mortality in the EU has declined significantly from 8,3 to 3,6 per 1,000 live births (annual percent change=-3,8%; 95% confidence interval, -4,1 to -3,6). Among EU countries, we found the highest mortality rates throughout the study period in Romania and Bulgaria, and the lowest rates in Scandinavian countries (Finland, Sweden). There were significant decreasing trends in every country of the EU, which were most pronounced in former Soviet Baltic states and Eastern European countries, and least pronounced in Western European countries. Mortality rates have increased significantly in Greece in the last years, and plateaued in the United Kingdom and Ireland. CONCLUSIONS: Our findings, which are based on official data, provide consistent evidence that infant mortality has declined steadily in the EU and its member states in the past decades, most markedly in Eastern European countries and former Soviet Baltic states. However, rates have risen or levelled off in some western countries in the past few years.

[Allergies in children due to early food consumption in Barranquilla, Colombia]. / Presencia de alergias en menores por consumo temprano de alimentos en Barranquilla, Colombia.

OBJECTIVE: To determine the prevalence of symptoms associated with asthma, rhinitis and eczema with food intake in children under six years of age. MATERIALS AND METHODS: Descriptive study on the prevalence of asthma, rhinitis and eczema and their correlation with food consumption. Information was obtained from 1 520 schoolchildren of the District of Barranquilla and its metropolitan area. The ISSAC method was used to process the information, which was provided by the child's guardian, using the software SPSS version 24. Only duly completed questionnaires with informed consents were considered. Analysis was made using a chi-squared test, with a significant P value and 95% confidence. RESULTS: In the 1 520 children surveyed, the type of food related to allergies was fish, associated with asthma, showing that this may be a protective factor for the population regarding the onset of eczema, with a statistically a P value of <0.05, chi-square of 4.566, and CI of 95% [0.3;0.8]. CONCLUSIONS: The analyzed foods showed that fish is related and associated as a protective factor for eczema, while the consumption of cow's milk was related as a protective factor for rhinitis. Regarding other foods and allergies, the study is not conclusive as to whether their early intake is a predisposing factor or trigger in children.

OBJETIVO: Determinar la prevalencia de síntomas asociados a asma, rinitis y eccema relacionada con la ingesta de alimentos en menores de seis a siete años. METODOLOGÍA: Estudio descriptivo de prevalencia de asma, rinitis y eccema y la relación con el consumo de alimentos. Información obtenida en 1 520 escolares del Distrito de Barraquilla y su área metropolitana. Se empleó metodología ISSAC procesándose la información mediante el software SPSS versión 24 El cuestionario fue contestado por el acudiente del menor y solo se tuvieron en cuenta los que tenían debidamente diligenciado los consentimientos informados Se hizo análisis empleando Chi-cuadrado, y el valor P de significancia con un 95% de confianza. RESULTADOS: Para los 1 520 menores encuestados el alimento que presentó relación con alergias fue el pescado asociándolo con el asma, evidenciando que en la población puede ser factor protector para la aparición de eccema mostrando estadísticamente una P<0,05, un Chi-cuadrado: 4,566, IC 95% [0,3;0,8]. CONCLUSIONES: De los alimentos analizados el pescado es uno que presentó relación y se asoció como factor protector para el eccema, el consumo de la leche de vaca se relacionó como factor protector para rinitis; en lo referente a los demás alimentos y las alergias el estudio no es conclusivo en cuanto a si la ingesta temprana es un factor predisponente o desencadenante de ellas en los menores, o no lo son.

Associations of neighborhood environmental attributes with adults' objectively-assessed sedentary time: IPEN adult multi-country study.

Neighborhood environmental attributes have been found to be associated with residents' time spent walking and in physical activity, in studies from single countries and in multiple-country investigations. There are, however, mixed findings on such environmental relationships with sedentary (sitting) time, which primarily have used evidence derived from single-country investigations with self-reported behavioral outcome measures. We examined potential relationships of neighborhood environmental attributes with objectively-assessed sedentary time using data from 5712 adults recruited from higher and lower socio-economic status neighborhoods in 12 sites in 10 countries, between 2002 and 2011. Ten perceived neighborhood attributes, derived from an internationally-validated scale, were assessed by questionnaire. Sedentary time was derived from hip-worn accelerometer data. Associations of individual environmental attributes and a composite environmental index with sedentary time were estimated using generalized additive mixed models. In fully adjusted models, higher street connectivity was significantly related to lower sedentary time. Residential density, pedestrian infrastructure and safety, and lack of barriers to walking were related to higher sedentary time. Aesthetics and safety from crime were related to less sedentary time in women only. The predicted difference in sedentary time between those with the minimum versus maximum composite environmental index values was 71 min/day. Overall, certain built environment attributes, including street connectivity, land use mix and aesthetics were found to be related to sedentary behavior in both expected and unexpected directions. Further research using context-specific measures of sedentary time is required to improve understanding of the potential role of built environment characteristics as influences on adults' sedentary behavior.
