Fundamento y generalidades de la construcción de modelos estadísticos multinivel en el ámbito de la investigación en salud / Construction of multilevel statistical models in health research: Foundations and generalities

Este trabajo tiene como objetivo presentar una mirada global de la aplicabilidad de los modelos de análisis multinivel en el ámbito de la investigación sanitaria. Ofrece información sobre los fundamentos teóricos, metodológicos y estadísticos y, además, menciona los pasos básicos para la construcción de estos modelos, y da ejemplos de su uso, según la estructura jerárquica de los datos. Cabe resaltar que, antes de utilizar estos modelos, se requiere contar con un soporte teórico sobre la necesidad de uso y una valoración estadística que dé cuenta del porcentaje de varianza explicada por el efecto de agrupación de las observaciones. Los requisitos para llevar a cabo este tipo de análisis dependen de condiciones especiales como el tipo de variables, la cantidad de unidades por nivel o el tipo de estructura jerárquica. Se concluye que los modelos de análisis multinivel son una herramienta útil para lograr la integración de información, dadas la complejidad de las relaciones y las interacciones que determinan la mayoría de las condiciones de salud, incluida la pérdida de independencia entre las unidades de observación.

This topic review aims to present a global vision of multilevel analysis models' applicability to health research, explaining its theoretical, methodological, and statistical foundations. We describe the basic steps to build these models and examples of their application according to the data hierarchical structure. It ir worth noticing that before using these models, researchers must have a rationale for needing them, and a statistical evaluation accounting for the variance percentage explained by the observations grouping effect. The requirements to conduct this type of analysis depends on special conditions such as the type of variables, the number of units per level, or the type of hierarchical structure. We conclude that multilevel analysis models are a useful tool to integrate information, considering the complexity of the relationships and interactions involved in most health conditions, including the loss of independence between observation units.

Mortality due to traffic accidents in Colombia: Profiles of pedestrians and cyclists, 1998-2019.

Background: Traffic accidents are an important issue for public health and a threat for sustainable development, with pedestrians and cyclists having been recognized as the most vulnerable actors on the streets. The objective of this study was to analyze the profiles of pedestrians and cyclists who died as a result of traffic accidents in Colombia during the 1998-2019 period. Methods: An observational and descriptive study, with the deaths due to traffic accidents in Colombia between 1998 and 2019 as data source. Secondary data were taken from the Vital statistics of Colombia (EEVV), published by Departamento Administrativo Nacional de Estadística (DANE). A trend analysis of the number of deaths during the period under study was performed, and such number was examined against sex to identify potential differences. Multiple correspondence analysis was employed to elaborate the profile of pedestrians and cyclists who die due to traffic accidents. Three profiles were prepared for each road actor: a global profile, one for 1998, and another for 2019. Results: The mortality profiles are different for pedestrians and cyclists, and, in turn, there are also demographic, geographic, and socioeconomic conditions in each type of road actor, which determine higher mortality risks. High population density, younger age group in the cyclists and adults among the pedestrians, low schooling levels and absence of health insurance are suggested as key factors in these profiles. Related to sex, for men is not possible to establish a profile. Women's cases are commonly related to health insurance, age, and population density. Conclusions: Several contextual and demographic characteristics in pedestrians and cyclists allow delimiting mortality profiles. The profiles that were identified suggest the need to articulate road safety policies with other social and development policies in order to coordinate and integrate intersectoral actions that reduce mortality in these road actors.

[Social inequalities related to road traffic mortality]. / Desigualdades sociales relacionadas con la mortalidad por accidentes de tráfico.

OBJECTIVE: To synthesize the social inequalities related to mortality from traffic accidents reported in scientific publications. METHOD: A scoping review following the PRISMA-ScR guide was carried out. Using the MesH vocabulary, we systematically searched for articles in English, Portuguese and Spanish published in the EBSCO, Scielo, Scopus, Ovid, and PubMed databases. RESULTS: We identified 47,790 records in the initial search, of which 35 articles met the selection criteria. Nine out ten publications are in high-income countries; there is a greater interest in analyzing mortality in occupants and drivers of vehicles and motorcyclists. Half of the publications use race-ethnicity and geolocation as socioeconomic position variables. The articles included in this review indicate that groups of people with low socioeconomic positions have higher mortality due to traffic accidents. CONCLUSIONS: The highest mortality from traffic accidents occurs in people with low socioeconomic positions which suggests the development of road safety actions from a comprehensive, integrative perspective and linked to other political agendas to reduce their incidence by 2030. Although road traffic fatalities are higher in low and middle-income countries, few publications are available in these countries. It is necessary to strengthen the research capacities in these countries.

Exposición a material particulado y su relación con el cáncer de mama. Mecanismos fisiopatológicos / Exposure to particulate matter and its association to breast cancer. Pathophysiological mechanisms

Introducción. El cáncer de mama es el tipo de cáncer que genera más muertes en mujeres en el mundo. Aunque se reconoce el aporte de factores genéticos, hormonales y de estilos de vida como sus principales causas, las hipótesis que señalan que la contaminación del ambiente juega un papel importante en su desarrollo, han tomado mucha fuerza en los últimos años. Estas hipótesis surgen debido a que el aumento en la incidencia del cáncer de mama coincide con procesos de industrialización, además de mayor presencia en regiones urbanas y con altos niveles de contaminación. El objetivo de este artículo fue consolidar información sobre los mecanismos fisiopatológicos que puedan explicar la relación entre cáncer de mama y la contaminación por material particulado. Metodología. Se realizó una búsqueda de literatura en PubMed, Google Académico y Epistemonikos para documentos publicados sobre el tema desde enero de 2016 hasta el 3 de agosto de 2022. Resultados. Se encontró que algunos de los mecanismos que podrían explicar dicha relación incluyen: alteraciones endocrinas que favorecen cambios hormonales, induciendo el crecimiento mamario; cambios en las características histológicas del tejido normal, como involución reducida de unidades lobulares ductales terminales; formación de aductos de hidrocarburos aromáticos policíclicos-ácido desoxirribonucleico (HAP-ADN), con mutación específica del gen TP53; activación de la proliferación en la línea celular MCF-7; y, alteraciones en la metilación del ADN. Conclusión. Si bien órganos distales como la mama no son la primera entrada de los contaminantes ambientales al cuerpo, estos sí pueden verse afectados tras la exposición a largo plazo, a través de diferentes mecanismos de disrupción endocrina y daño al ADN principalmente

Breast cancer is the type of cancer that causes the most deaths in women worldwide. Although the contribution of genetic, hormonal and lifestyle factors are recognized as its main causes, the hypotheses that indicate that environmental pollution has an important role in its development have taken on great strength during the last years. These hypotheses are based on the increase in the incidence of breast cancer that coincides with industrialization processes, in addition to its greater presence in urban regions with high levels of pollution. The aim of this study was to consolidate information on the pathophysiological mechanisms that can explain the relationship between breast cancer and air pollution by particulate matter. Methodology. A literature search was carried out in PubMed, Google Scholar and Epistemonikos for documents published on this topic from January 2016 until August 3rd 2022. Results. Some of the mechanisms that could explain this association include endocrine alterations that favor hormonal changes, inducing breast growth; changes in the histological characteristics of normal tissue such as reduced involution of terminal duct lobular units; formation of polycyclic aromatic hydrocarbons-deoxyribonucleic acid (PAH-DNA) adducts, with specific mutation of the TP53 gene; an increase in cell proliferation in the MCF-7 cell line; and alterations in DNA methylation. Conclusion. Although distal organs such as the breast are not the entry site of environmental pollutants into the body, they can be affected after prolonged exposure, mainly through different mechanisms of endocrine disruption and DNA damage

La antifragilidad: Una mirada positiva del envejecimiento

Este artículo pretende explorar el concepto de antifragilidad en el adulto mayor, dado el cambio demográfico en el mundo, con evidencia del aumento de personas mayores, que exige a los profesionales vinculados a su atención implementar modelos de intervención acordes con sus necesidades, relacionadas con su capacidad funcional y promoción de una cultura de antifragilidad. La construcción teórica de lo que significa ser adulto mayor antifrágil, en una sociedad que asimila el envejecimiento con fragilidad, enfermedad y discapacidad, es una oportunidad para presentar una mirada positiva de la salud en la vejez, a partir de las adaptaciones al estrés en diferentes dimensiones que influencian la vida de este grupo poblacional, en el que el capital físico, psicológico y social se integran e influencian, en un proceso que se relaciona con la antifragilidad y el envejecer como un continuo de la vida, con ganancias y pérdidas; el estudio de esta relación permitirá contar con políticas inclusivas adecuadas en cada etapa de la vida.

This article intends to explore the concept of anti-fragility in the elderly, given the demographic change in the world, with evidence of the increase in the number of elderly people, which requires professionals linked to their care, to implement intervention models in accordance with their needs, related to their functional capacity and promotion of a culture of antifragility. The theoretical construction of what it means to be an anti-fragile older adult, in a society that assimilates aging with frailty, illness and disability, is an opportunity to present a positive view of health in old age, based on the adaptations to stress in different dimensions that influence the life of this population group, in which physical, psychological and social capital are integrated and influenced, in a process that is related to anti-fragility and aging as a continuum of life, with gains and losses; the study of this relationship will make it possible to have appropriate inclusive policies at each stage of life.

Friends, physical activity, and sedentary behavior in university students: A social network analysis / Amigos, actividad física y comportamiento sedentario en estudiantes universitarios: un análisis de redes sociales

Abstract Introduction: Understanding the processes of socialization during youth and their association with healthy behaviors is crucial for university education. Objective: To explore the associations of the characteristics of friendship networks with being physically active and having a sedentary behavior in university students. Materials and methods: Cross-sectional study conducted in 475 university students and based on a social network analysis. Measurements included sociodemographic, physical activity, sedentary behavior, and friendship network variables. The associations between the characteristics of friendship networks and physical activity and sedentary behavior were explored using logistic regression models. Confidence intervals (95%) were estimated and a significance level of p<0.05 was considered. Results: In women, being part of at least a cluster of friends was significantly associated with being physically active (adjusted OR [aOR]: 2.3; 95%CI: 1.2-4.6), while being popular was significantly associated with a lower probability of being physically active (aOR: 0.3; 95%CI: 0.1-0.7). Also, a ten-percentage point increase in active friends was significantly associated with a higher probability of being physically active (aOR: 9.3; 95%CI: 3.5-24.6). Regarding sedentary behavior, a ten-percentage point increase in the number of sedentary friends was significantly associated with a higher probability of being sedentary (aOR: 5.5; 95%CI: 2.5-12.3). In men, none of the studied associations were statistically significant. Conclusion: Some characteristics of social network are relevant for female university students in relation to their physical activity levels and sedentary behaviors. These findings highlight the need to consider friendship network dynamics for designing initiatives aimed at physical activity promotion and sedentary behavior reduction.

Resumen Introducción. El entendimiento de los procesos de socialización durante la juventud y su relación con conductas saludables son cruciales para la educación universitaria. Objetivo. Explorar las asociaciones de las características de la red social de amigos con ser físicamente activo y con tener un comportamiento sedentario en estudiantes universitarios. Materiales y métodos. Estudio transversal, basado en un análisis de redes sociales, realizado en 475 estudiantes universitarios. Las mediciones realizadas incluyeron variables sociodemográficas, actividad física, conducta sedentaria y redes sociales de amigos. Las asociaciones entre las características de la red social de amigos con la actividad física y el comportamiento sedentario fueron exploradas mediante modelos de regresión logística. Se estimaron intervalos de confianza (95%) y se consideró un nivel de significancia de p<0.05. Resultados. En mujeres, ser parte de al menos un conglomerado de amigos se asoció significativamente con ser físicamente activa (OR ajustados: 2.3; IC95%: 1.2-4.6), mientras que ser popular se asoció significativamente con una menor probabilidad de ser físicamente activa (OR ajustados [aOR]: 0.3; IC95%: 0.1-0.7). Asimismo, un incremento de diez puntos porcentuales de amigos activos se asoció significativamente con una mayor probabilidad de ser físicamente activa (aOR: 9.3; IC95%: 3.5-24.6). En relación con el comportamiento sedentario, un incremento de diez puntos porcentuales de amigos sedentarios se asoció significativamente con una mayor probabilidad de ser sedentaria (aOR: 5.5; IC95%: 2.5-12.3). En hombres, ninguna de las asociaciones estudiadas fue estadísticamente significativa. Conclusión. Algunas características de las redes sociales de amigos fueron relevantes para las estudiantes universitarias en relación a sus niveles de actividad física y comportamiento sedentario. Estos hallazgos resaltan la necesidad de considerar las dinámicas de las redes sociales de amigos en el diseño de iniciativas orientadas a la promoción de la actividad física y la reducción de conductas sedentarias.

Factors Associated With Suicidal Ideation in Older Adults From Three Cities in Colombia, 2016. / Factores asociados con la ideación suicida del adulto mayor en tres ciudades de Colombia, 2016.

INTRODUCTION: Suicidal ideation refers to thoughts that range from a vague idea of committing suicide to a specific suicide plan. OBJECTIVE: To explore factors such as demographic, social, family, abuse, risk of depression, habits and health conditions, which influence suicidal ideation in the elderly people in the cities of Medellín, Barranquilla, and Pasto (Colombia), with the intention to identify those associated factors that can be used in public health programs focused on this population. METHODS: Cross-sectional analytical study was conducted using a secondary source, demographic, social, clinical variables, social support, discrimination, abuse, happiness, depression, functional capacity, and as a dependent variable were asked the question: "Have you ever thought about committing suicide?" A descriptive, bivariate and multivariate analysis was performed. RESULTS: The median age was ≤ 69 [interquartile range, 11] years, and 58.2% were women. The prevalence of suicidal ideation was 6.4%, and of these, 28.7% had made plans to end their lives, and 66.7% had tried at least once. A statistical association was found with informal employment, cigarette consumption, alcohol and psychoactive substances, risk of depression, having a disability, dissatisfaction with their quality of life, with their health, with their economic situation, as well as feeling unhappy, bad treatment and bad relationships among family members, poor social support, sexual and economic abuse, and finally, discrimination. CONCLUSIONS: Suicidal ideation in older adults in three cities of Colombia is explained by the sexual and economic abuse that this population is suffering, as well as bad personal relationships between the members of the family of the older adult. The risk of depression increases the probability of having thoughts against one's life.

Factores asociados con la ideación suicida del adulto mayor en tres ciudades de Colombia, 2016 / Factors Associated With Suicidal Ideation in Older Adults From Three Cities in Colombia, 2016

RESUMEN Introducción: La ideación suicida se refiere a pensamientos que abarcan desde una vaga idea de suicidarse a un plan específico de suicidio. Objetivo: Explorar factores demográficos, sociales y familiares, maltrato, riesgo de depresión y hábitos y condiciones de salud que influyen en la ideación suicida del adulto mayor en las ciudades de Medellín, Barranquilla y Pasto, para identificar aquellos en los que se puede intervenir con programas de salud pública enfocados en esta población. Métodos: Estudio analítico transversal con fuente secundaria; se consideraron variables demográficas, sociales y clínicas, apoyo social, discriminación, maltrato, felicidad, depresión y capacidad funcional, y como variable dependiente, la pregunta: «¿ha pensado en atentar contra su vida?¼. Se realizaron análisis descriptivo, bivariable y multivariable. Resultados: La mediana de edad fue ≤ 69 (intervalo intercuartílico, 11) años; el 58,2% eran mujeres; la prevalencia de ideación suicida fue del 6,4%; el 28,7% de estos había hecho planes para terminar con su vida y el 66,7% lo había intentado al menos una vez. Se encontró asociación estadística con el empleo informal, el consumo de cigarrillos, alcohol y sustancias psicoactivas, el riesgo de depresión, tener discapacidad, la insatisfacción con la calidad de vida, la salud y la situación económica, sentirse infeliz, los maltratos y las malas relaciones entre los miembros de la familia, el escaso apoyo social, el maltrato sexual y económico y, por último, la discriminación. Conclusiones: La ideación suicida de los adultos mayores en 3 ciudades de Colombia se explica por el maltrato sexual y económico que sufre esta población; asimismo las malas relaciones personales entre los miembros de la familia del adulto mayor y el riesgo de depresión aumentan la probabilidad de que se presenten pensamientos contra la propia vida.

Introducción: El aislamiento social durante la pandemia por COVID-19 incluye el confinamiento en casa, que redunda en incremento de la inactividad física y de comportamientos sedentarios, favoreciendo el desacondicionamiento físico. Las personas desacondicionadas físicamente tienen alteraciones metabólicas y sistémicas por la falta de movimiento. Objetivo: Presentar recomendaciones prácticas, y de bajo costo sobre actividades basadas en la evidencia para evitar el desacondicionamiento físico durante el confinamiento en casa, que se pueden mantener a largo plazo, incluso después de la pandemia. Materiales y métodos: Revisión documental sobre estrategias para conducir estilos de vida saludable en casa que disminuyan los efectos negativos a nivel fisiológico producidos por el confinamiento derivado de la pandemia. Resultados: La evidencia señala que el confinamiento en casa incrementa los niveles de inactividad física y el comportamiento sedentario; la realización de actividad física bajo condiciones particulares puede entre otros, fortalecer el sistema respiratorio e inmunológico, mantener la condición física y generar efectos positivos sobre la salud mental. Conclusiones: Los hábitos relacionados con la práctica de actividad física en casa se deben mantener en el tiempo, se recomienda realizarla de manera programada, establecer horarios de descanso entre las actividades y durante la noche, y elegir aquellas que generen disfrute.

Introduction: Social isolation during the COVID-19 pandemic includes home confinement, which results in increased physical inactivity and sedentary behaviors, favoring physical deconditioning. Deconditioned people have metabolic and systemic disorders due to the lack of movement. Objective: To present practical, low-cost recommendations on evidence-based activities to avoid physical deconditioning during home confinement, which can be maintained over the long term, even after the pandemic. Materials and methods: Documentary review on strategies to support healthy lifestyles at home that decrease the negative effects at a physiological level produced by the confinement derived from the pandemic. Results: Evidence indicates that home confinement increases the levels of physical inactivity and sedentary behavior; executing physical activity under particular conditions, among other effects, can strengthen the respiratory and immune systems, maintain physical condition and generate positive effects on mental health. Conclusions: The habits related to the practice of physical activity at home should be maintained over time, it is recommended to do it on a scheduled basis, define rest times between activities and during the night, and choosing those that generate enjoyment.

Abstract Objective: To determine the predictive capacity of happiness on the family functioning of the elderly in three cities of Colombia. Materials and methods: Analytical, cross sectional, primary source study with 1514 surveys applied to people aged 60 and older, residents in the cities of Medellín, Barranquilla and Pasto in 2016. Family functionality was explored with the family APGAR scale, along with demographic, social and the physical, mental, functional and health status of the elderly. Univariate, bivariate and multivariate analyzes were carried out to adjust the confounding variables and a predictive model was calculated with the backward method (Wald). Results: The characteristics associated to family functioning were: city of residence, female gender, having a sentimental partner, high educational level, not suffering from mental disorders, perception of happiness without risk of depression, low vulnerability, and having social support. The characteristics that contributed to this prediction were: being a woman, being happy, not having depression, not being vulnerable, having adequate instrumental and social support, and not having been mistreated. Happiness is the greatest predictor according to the calculated model with sensitivity of 92.6% and specificity of 40.8%. Conclusion: if the subjective well-being of the elder is strengthened, it will be possible to see old age with a positive image as a facilitator of good family relationships and an active member of society.

Entornos y actividad física en enfermedades crónicas: Más allá de factores asociados / Environments and physical activity in chronic diseases: Beyond associated factors

Resumen Introducción: Las enfermedades crónicas no transmisibles son la mayor causa de morbimortalidad. La estrategia más costo-efectiva es la realización de actividad física pero hay una relación directa entre el incremento de estas enfermedades con la alta prevalencia de personas físicamente inactivas. Objetivo: Recoger los elementos esenciales de las enfermedades crónicas en términos del impacto y sus efectos negativos y mostrar, dentro de los factores de riesgo, a la inactividad física como uno de los determinantes clave en su aparición y el rol de los entornos construidos en esta conducta no saludable. Materiales y métodos: Estudio descriptivo mediante revisión documental sobre el papel de los entornos como factores determinantes entre la inactividad física y el desarrollo de las enfermedades crónicas no transmisibles. Resultados: Se describen los efectos negativos de las enfermedades crónicas, los factores que influyen en su aparición y se destaca a la inactividad física como uno de los determinantes de las enfermedades crónicas. La evidencia empírica sugiere que las características del entorno obran como determinantes en este comportamiento dentro de los estilos de vida. Conclusión: Los entornos en que habitan las personas se constituyen en factores asociados y determinantes en la realización o no de actividad física y deben ser considerados, más allá de los factores individuales, si se quiere tener éxito en la prevención y control de las enfermedades no transmisibles.

Abstract Introduction: Chronic noncommunicable diseases are the major cause of morbidity and mortality. The most cost-effective strategy is the practice of physical activity but there is a direct relationship between the increase of these diseases with the high prevalence of physically inactive people. Objective: To collect the essential elements of chronic diseases in terms of impact and their negative effects and to show, within risk factors, physical inactivity as one of the key determinants in their emergence and the role of environments built on this unhealthy behavior. Materials and methods: A descriptive study was conducted through documentary review on the role of environments as determinants between physical inactivity and the development of chronic noncommunicable diseases. Results: The negative effects of chronic diseases are described as well as the factors that influence their appearance. Physical inactivity is highlighted as one of the determinants of chronic diseases. The empirical evidence suggests that the characteristics of the environment work as determinants in this behavior within the lifestyles. Conclusion: The environments where people inhabit are associated factors and determinants in the practice or not of physical activity and should be considered, beyond the individual factors, if there is the need to succeed in the prevention and control of noncommunicable diseases.

Evidence-based practice: beliefs, attitudes, knowledge, and skills among Colombian physical therapists.

OBJECTIVE: The main purpose of this study was to describe a group of Colombian physical therapists' beliefs and attitudes towards Evidence-Based Practice (EBP), their education, knowledge and skills for implementing EBP, the use of relevant literature in clinical practice, access to and availability of scientific information and perceived barriers to including EBP in practice. METHODS: This was a cross-sectional study which involved 1,064 Colombian physical therapists. The study used a 50-item screening questionnaire EBP developed to estimate attitudes, beliefs, knowledge and skills regarding. This instrument has been adapted and was validated previously in Colombia by Flórez-López et al. RESULTS: The population mostly consisted of young females (77.2%) aged 22 to 29 years old (79.4%). Most respondents had an undergraduate degree (87.7%). The physical therapists stated that they had positive attitudes and beliefs regarding EBP, most of them answering that they agreed or strongly agreed that EBP is necessary (71.6%), the relevant literature is useful for practice (61.3%), EBP improves the quality of patient care (64.1%) and evidence helps in decision-making (44.5%). Forty-one percent of the respondents indicated that a lack of research skills was the most important barrier to the use of evidence in practice. CONCLUSION: The physical therapists reported that they had a positive attitude to EBP and were interested in learning about or improving the skills necessary to adopt EBP in their clinical practice.

OBJETIVO: Describir en un grupo colombiano de fisioterapeutas las i) creencias y actitudes hacia la practica basada en la evidencia (PBE), ii) la educación, el conocimiento y las habilidades para implementar la PBE; iii) el uso de la literatura relevante en la práctica clínica; iv) el acceso y la disponibilidad de información científica; y v) la percepción de las barreras para la inclusión de la PBE. MÉTODOS: Se realizó un estudio transversal en 1,064 fisioterapeutas colombianos. El estudio usó el cuestionario que consta de 50-ítems para estimar las actitudes, creencias, conocimientos y habilidades hacia la PBE. Dicho instrumento fue adaptado y validado en Colombia por Flórez-López et al. RESULTADOS: La mayoría de la población participante fueron mujeres (77.2%) en edades comprendidas entre 22 y 29 años (79.4%). El 87.7% de los encuestados eran titulados en fisioterapia. Los fisioterapeutas manifestaron tener actitudes y creencias positivas hacia la PBE. Una mayoría respondió que estaba de acuerdo o muy de acuerdo en que es necesaria la PBE (71.6%), en que la literatura es útil para la práctica clínica (61.3%), que la PBE mejora la calidad de la atención a los pacientes (64.1%), y en que la evidencia ayuda en la toma de decisiones clínicas (44.5%). El 41.0% de los encuestados indicaron que la falta de habilidades de investigación era la barrera más importante para el uso de la evidencia científica en la práctica clínica. CONCLUSIONES: Los fisioterapeutas manifestaron una actitud positiva acerca la PBE y estaban interesados en aprender o mejorar las habilidades necesarias para adoptar la PBE en la práctica clínica.

Evidence-based practice: beliefs, attitudes, knowledge, and skills among Colombian physical therapists / Práctica basada en la evidencia: creencias, actitudes, conocimientos y habilidades entre fisioterapeutas colombianos

Objective: The main purpose of this study was to describe a group of Colombian physical therapists' beliefs and attitudes towards Evidence-Based Practice (EBP), their education, knowledge and skills for implementing EBP, the use of relevant literature in clinical practice, access to and availability of scientific information and perceived barriers to including EBP in practice. Methods: This was a cross-sectional study which involved 1,064 Colombian physical therapists. The study used a 50-item screening questionnaire EBP developed to estimate attitudes, beliefs, knowledge and skills regarding. This instrument has been adapted and was validated previously in Colombia by Flórez-López et al. Results: The population mostly consisted of young females (77.2%) aged 22 to 29 years old (79.4%). Most respondents had an undergraduate degree (87.7%). The physical therapists stated that they had positive attitudes and beliefs regarding EBP, most of them answering that they agreed or strongly agreed that EBP is necessary (71.6%), the relevant literature is useful for practice (61.3%), EBP improves the quality of patient care (64.1%) and evidence helps in decision-making (44.5%). Forty-one percent of the respondents indicated that a lack of research skills was the most important barrier to the use of evidence in practice. Conclusion: The physical therapists reported that they had a positive attitude to EBP and were interested in learning about or improving the skills necessary to adopt EBP in their clinical practice.
