[Association of physical activity with quality of life in patients with chronic kidney disease]. / Actividad física y calidad de vida en personas con enfermedad renal crónica.

BACKGROUND: Physical activity may improve quality of life in patients with chronic kidney disease. AIM: To assess the relationship between physical activity and quality of life in patients with Chronic Kidney Disease. MATERIAL AND METHODS: The Kidney Disease Quality of Life-36 (KDQOL-36) and the International Physical Activity questionnaire were answered by 130 patients with chronic kidney disease (74 women, 80 receiving renal substitution therapy). Sociodemographic variables were recorded. RESULTS: Patients on renal substitution therapy with a time lapse since diagnosis of 0 to 6 months had higher levels of physical activity than those with longer time lapses (51.4 ± 12.5 and 34.6 ± 8.1 minutes respectively). Disease burden scores were lower among patients with renal substitution therapy. There was a direct correlation between levels of vigorous and moderate physical activity and the physical functioning dimension in the quality of life questionnaire for patients with more than 19 months of disease. The dimension general physical health was significantly associated with physical activity in women and patients with 7 to 18 months of diagnosis. The dimension disease burden was associated with physical activity in women, patients not receiving substitution therapy and those with 7 to 18 months of diagnosis. CONCLUSIONS: Moderate and vigorous physical activity is directly related to the dimensions physical functioning, the general perception of physical health and inversely related with the dimension burden of disease.

[Levels of physical activity among colombian university students]. / Factores sociodemográficos y motivacionales asociados a la actividad física en estudiantes universitarios.

BACKGROUND: Physical inactivity is an important risk factor for chronic diseases in Western societies. AIM: To determine the sociodemographic and motivational factors associated with physical activity in college students. MATERIAL AND METHODS: The International Physical Activity Questionnaire (IPAQ) -short form- and the "motives for physical activities measure-revised" (MPAM-R) questionnaire were applied to 900 university students aged 20 ± 3 years (60% women). The frequency, level and motivations for engaging in physical activity and associated demographic factors were analyzed. RESULTS: Twenty two percent of students were classified as having a high level of physical activity, 54.8% had a low level and 13.9% were considered inactive. According to MET consumption, 68.9% of students are inactive and only 16.8% of students classified as very active. Ninety two percent of active students performed physical activity for health reasons. A significant association between gender and social motivation was observed. CONCLUSIONS: A high prevalence of physical inactivity was found in these students. Males showed higher levels of physical activity than females.

Evaluation of the psychometric properties of the family adaptability and cohesion scale (FACES III) through item response theory models in students from Chile and Colombia.

BACKGROUND: A psychometric study of the Family Adaptability and Cohesion Scale (FACES III) has been conducted in Spanish-speaking countries from the perspective of the classical test theory. However, this approach has limitations that affect the psychometric understanding of this scale. OBJECTIVE: Accordingly, this study used the item response theory to investigate the psychometric performance of the items. Furthermore, it evaluated the differential performance of the items for Colombia and Chile. METHOD: For this purpose, 518 health science students from both countries participated. Confirmatory Factor Analysis was used. RESULTS: The study results revealed that the cohesion and adaptability items presented adequate discrimination and difficulty indices. In addition, items 5, 8, 13, 17, and 19 of cohesion indicated differential functioning between students from both countries, with Chilean students exhibiting a greater discriminatory power. Further, the Colombian group exhibited a greater discriminatory power for item 18 of adaptability. CONCLUSIONS: The study concluded that the items of FACES III indicated adequate psychometric performance in terms of their discriminative capacity and difficulty in Chile and Colombia.

Reductions in systolic blood pressure achieved by hypertensives with three isometric training sessions per week are maintained with a single session per week.

Isometric handgrip or (wall) squat exercise performed three times per week produces reductions in systolic blood pressure (SBP) in adults with hypertension. We aimed to compare these interventions and the potential to retain benefits with one exercise session per week. We compared blood pressure changes following handgrip and squat isometric training interventions with controls in a randomized controlled multicentre trial in 77 unmedicated hypertensive (SBP ≥ 130 mmHg) adults. Exercise sessions were performed in the workplace and consisted of four repetitions-three sessions per week for the first 12 weeks (phase 1), and one session per week for the subsequent 12 weeks (phase 2). Office blood pressure (BP) was measured at baseline, post-phase 1 and post-phase 2. Post-phase 1, mean reductions in SBP were significantly greater in handgrip (-11.2 mmHg, n = 28) and squat (-12.9 mmHg, n = 27) groups than in controls (-.4 mmHg; n = 22) but changes in DBP were not. There were no significant within-group changes during phase 2 but SBP was 3.8 mmHg lower in the wall squat than the handgrip group-a small magnitude but clinically important difference. While both interventions produced significant SBP reductions, the wall squat appears to be more effective in maintaining benefits with a minimal training dose. The low time investment to achieve and retain clinically significant SBP reductions-42 and 12 min, respectively-and minimal cost, particularly of the wall squat, make it a promising intervention for delivery in public health settings.

[Level of physical activity, sedentary behavior, and sleep in the early childhood population]. / Nivel de actividad física, comportamiento sedentario y sueño en la población de la primera infancia.

INTRODUCTION: Introduction: the daily general activity pattern of preschool aged children is composed of sleep time, sedentary time, and physical activity of mild, moderate, or vigorous intensity. Objective: to determine the compliance with the recommendations for physical activity, sedentary behavior, and sleep according to the days of the week, sex, and age in children aged from 2 to 5 years. Methods: a cross-sectional study in 361 preschool aged boys and girls. The Questionnaire for the Measurement of Physical Activity and Sedentary Behavior in Children from Preschool to 4th grade (C-MAFYCS) was used, which inquires about three behaviors (physical activity, sedentary behavior, and sleep). The statistical analysis was carried out using the SPSS, version 24 program (Simón Bolívar University license). Results: on average, children perform 132.4  95.2 minutes of physical activity and spend 70.4  63.4 minutes per day in sedentary behaviors. The time dedicated to active play and organized sport is greater on Saturdays and Sundays (175.1  140 minutes) (p = 0.0001). The time spent watching television was greater during the weekend (70.7  69.4 minutes). On average, preschoolers sleep 10.2  0.9 hours per day, less during the week (9.3  0.7 minutes). Conclusions: balance between these behaviors is essential for the health of children in this first stage of life. It is essential that parents, caregivers, and the community in general attend to the healthy lifestyles of this population since these are patterns that are learned and acquired to remain in the following stages of the life cycle.

INTRODUCCIÓN: Introducción: el patrón de actividad general diario en la edad preescolar se compone de tiempo de sueño, tiempo sedentario y actividad física de intensidad ligera, moderada o vigorosa. Objetivo: determinar el cumplimiento de las recomendaciones de actividad física, comportamiento sedentario y sueño según los días de la semana, el sexo y la edad de los niños (as) entre 2 a 5 años. Métodos: estudio de corte transversal y analítico en 361 niños y niñas en edad preescolar. Se usó el Cuestionario para la Medición de Actividad Física y Comportamiento Sedentario en niños de Preescolar a Cuarto Grado (C-MAFYCS), que indaga sobre tres comportamientos (actividad física, comportamiento sedentario y sueño). El análisis estadístico se realizó en el programa SPSS, versión 24 (licencia de la Universidad Simón Bolívar). Resultados: en promedio, los niños realizan 132,4  95,2 minutos de actividad física y gastan 70,4  63,4 minutos por día en comportamientos sedentarios. Es mayor el tiempo dedicado al juego activo y al deporte organizado durante los sábados y domingos (175,1  140 minutos) (p = 0,0001). El tiempo dedicado a ver televisión fue mayor durante el fin de semana (70,7  69,4 minutos). En promedio, los prescolares duermen 10,2  0,9 horas por día, siendo menor el tiempo de sueño entre semana (9,3  0,7 minutos). Conclusiones: el equilibrio entre estos comportamientos es fundamental para la salud del niño en esta primera etapa de la vida. Es fundamental que los padres, los cuidadores y la comunidad en general atiendan los estilos de vida saludables de esta población dado que son patrones que se aprenden y adquieren para permanecer en los siguientes momentos del ciclo vital.

Restrictions on persons with disabilities for participating in family and community activities.

OBJECTIVE: To identify the influence of functional impairments and limitations activities for persons with disabilities to particípate in family and community activities. METHODS: This is a cross-sectional study with 4 044 persons with disabilities, selected using probabilistic sampling and a door-to-door active search model in 5 towns in the District of Barranquilla. The data were processed with univariate analysis and bivariate analysis to determine the relationship between the study variables. RESULTS: 55.9% of the population were males, 41.6% were between 15 and 44 years of age, and 92.9% belonged to the lower socioeconomic stratum. 82.9% reported mobility limitations and 99% reported barriers to access non-formal learning activities, 98.6% to access public activities, and 97.5% to access productive activities. Individuals with that a lower limitation in exercising the power of reason, particularly thinking, can increase participation in activities with family and friends (OR, 0.8; 95% CI, 0.6-0.9), with the community (OR, 0.7; 95% CI, 0.6-0.9), religious or spiritual activities (OR, 0.8; 95% CI, 0.7-0.9). CONCLUSIONS: There is a directly proportional relationship between structural impairment with the development of dependency and limited family, social, and work participation in the persons with disabilities.

User Preferences Related to Multimedia Elements of a Mobile Application to Prevent Diabetes.

OBJECTIVES: To understand user preferences related to the characteristics of an application that promotes and provides education on healthy habits to correctly design multimedia elements. METHODS: We conducted a comprehensive qualitative study with a hermeneutical strategy, which gathered information using well-researched questions that were posed to focus groups consisting of 32 participants. These participants were asked for opinions related to multimedia elements to display educational messages about physical activity and healthy eating in a mobile application. There were three analysis categories of multimedia elements: text, visual elements, and audio elements. RESULTS: The majority of the participants, 93.75%, were in the low socioeconomic stratum; 68.75% are in a civil union with their partner; 53.12% completed or failed to complete secondary school, and 68.75% were housewives. Based on the qualitative results, we found that mobile applications become mediating tools that support the adoption of actions that tend to improve lifestyles and increase knowledge about proper nutrition and physical activity. Text messages used in mobile applications should promote healthy habits and remind users of their benefits. Images and videos should be accompanied by text and audio to provide greater clarity regarding recommendations of healthy habits. CONCLUSIONS: Technology must provide accessibility and coverage opportunities, while meeting the needs and expectations of users. It should facilitate primary health intervention through education to transform unhealthy behaviors and generate lifestyles that improve the health of the user and their family context.

[Influence of daily and weekly activities in the physical activity levels of school children: a cross-sectional study]. / Influencia de las actividades del día y la semana en los niveles de actividad física de los escolares: estudio de corte transversal.

INTRODUCTION: Introduction: the distinct activities related to an active lifestyle that schoolchildren perform during the day and week interact to influence the children's total level of physical activity. Objective: to identify the influence that the activities developed by school children during the different times of the day and the week have on the levels of physical activity. Method: a cross-sectional study conducted in 3,598 public school students aged between 10 and 14 years. The demographic characteristics were evaluated, as well as the levels of physical activity through the Physical Activity Questionnaire for Schoolchildren (PAQ-C). A multivariate logistic regression analysis was performed as statistical analysis using the SPSS v.24 software program. The raw odds ratio (OR) was estimated. Results: in all, 64.3% of the students failed to comply with physical activity recommendations. Students who are more inactive include those who do not perform enough physical activity during the weekend [OR: 3.7 (95% CI: 2.9-4.5)], those who are not physically active after school [OR: 3.1 (95% CI: 2.3-4.2)], those who do not practice activities such as jumping in their free time [OR: 3.2 (95% CI: 1.9-5.2)], and those who do not ride a bicycle [OR: 3.7 (95% CI: 2.7-5.1)]. Conclusions: the levels of physical activity in students depend on the integration of different contexts and periods during the day and the week. The influence of weekend activities and physical education shows the role that the family and school play in the acquisition and practice of an active lifestyle.

INTRODUCCIÓN: Introducción: las diversas actividades relacionadas con un estilo activo que los escolares realizan durante el día y la semana interactúan para influir en el nivel total de actividad física de los niños. Objetivo: identificar la influencia que tienen las actividades ejecutadas por los escolares durante los diferentes momentos del día y la semana sobre los niveles de actividad física. Métodos: estudio de corte transversal analítico sobre 3598 estudiantes de escuelas públicas de entre 10 y 14 años de edad. Se aplicó una encuesta que midió las características sociodemográficas.

Son más inactivos los escolares que no realizan suficiente actividad física (AF) durante el fin de semana [OR: 3,7 (IC 95%: 2,9-4,5)], los que no son activos físicamente después de la escuela [OR: 3,1 (IC 95%: 2,3-4,2], los que no practican actividades como saltar en su tiempo libre [OR: 3,2 (IC 95%: 1,9-5,2] y los que no usan la bicicleta [OR: 3,7 (IC 95%: 2,7-5,1]. Conclusiones: los niveles de AF de los escolares dependen de la integración de diferentes contextos y periodos del día y la semana. La influencia de las actividades durante el fin de semana y la educación física muestra la función que tienen la familia y la escuela sobre la adquisición y práctica de estilos de vida activos.

[Physical activity level assessment in university students by direct method]. / Evaluación de los niveles de actividad física en universitarios mediante método directo.

OBJECTIVES: To identify the categories in which a group of university students are classified by directly measuring physical activity, and to relate these categories with socio-demographic and anthropometric variables. MATERIALS AND METHODS: Cross-sectional and comparative phase study in 601 university students who were interviewed to inquire about socio-demographic variables such as sex, age, marital status, socioeconomic status and self- perceived health. Body Mass Index (BMI) and physical activity levels were determined by applying the Perez-Rojas-García Sedentarism Classification Test on heart rate behavior. RESULTS: Significant heart rate differences (p=0.000) between the active and the inactive group of university students were observed. The inactive group had a heart rate of 143.4 bpm compared to 115.1 bpm in the active group. Regarding the results of the logistic regression, female students had a greater risk of being physically inactive in the objective test [OR 2.6 (1.9 to 3.6)], while overweight and obese people are more likely to be inactive [OR 1.9 (1.4-2.9)]. CONCLUSION: The assessment shows that a high prevalence of physical inactivity in university students is significantly associated with obesity and the female sex. This Information is fundamental for designing specific training programs and physical activities for university students.

OBJETIVO: Identificar a través de un método de medición directo de la actividad física, las categorías en las que se ubican un grupo de estudiantes universitarios; así como relacionar estas categorías con variables de tipo sociodemográfico y antropométrico. MÉTODOS: Estudio de corte transversal y fase comparativa en 601 estudiantes universitarios a los que se les indagó sobre las variables sociodemográficas: género, edad, estado civil y estrato socioeconómico y autopercepción de salud. Se determinó el Índice de Masa Corporal y los niveles de actividad física mediante el Test de Clasificación de Sedentarismo de Pérez-Rojas-García sobre el comportamiento de la frecuencia cardíaca. RESULTADOS: Se observó diferencias significativas (p=0,000) en la frecuencia cardíaca entre activos e inactivos, en los inactivos fue de 143,4 p/m en comparación con 115,1 p/m en los activos. Con respecto a los resultados de la regresión logística, los estudiantes de género femenino presentan mayor riesgo de ser inactivos físicamente con la prueba objetiva [OR 2,6 (1,9-3,6)]; asimismo, se observa que las personas con sobrepeso y obesidad tienen mayor probabilidad de ser inactivos [OR 1,9 (1,4-2,9)]. CONCLUSIÓN: Se evidencia una elevada frecuencia de inactividad física en la población universitaria, asociada significativamente a la obesidad y al género femenino, datos que se convierten en una línea de base fundamental para la elaboración de programas de entrenamiento y actividad física específicos para población universitaria.

Questionnaire in Colombian Third-Grade Elementary Schools / Reprodutibilidade do questionário POiBA-(como nos movemos?) em estudantes colombianos da terceira série do ensino fundamental

Introducción: disponer de instrumentos reproducibles que midan la actividad física y los comportamientos sedentarios es una prioridad para la vigilancia y promoción de estilos de vida saludables en niños y niñas. En esta investigación se evaluó la reproducibilidad prueba-reprueba del cuestionario POIBA-¿Cómo nos movemos? en escolares colombianos. Materiales y métodos: participaron 125 estudian- tes de tercer grado de primaria de una institución educativa colombiana. En dos ocasiones se aplicó el cuestionario POIBA-¿Cómo nos movemos?, que evalúa la actividad física realizada para transportarse a la institución educativa y desde esta, durante el tiempo escolar (clases de educación física y recreo), extraescolar (deportiva, con entrenador) y libre. Se emplearon índices kappa y kappa ponderado en los ítems categóricos y el coeficiente de correlación intraclase con modelo de efectos mixtos en los ítems con escala cuantitativa. Resultados: en los ítems sobre actividad física en el ámbito escolar y deportivo predominaron kappas superiores a 0.70. Las preguntas sobre el transporte a la institución educativa y desde esta tuvieron coeficientes kappa cercanos a 0.90. Los ítems de tiempo frente a pantallas alcanzaron coeficientes kappa alrededor de 0.5, y los correspondientes a la hora de acostarse y levantarse obtuvieron coeficientes de correlación intraclase entre 0.40 y 0.72. Conclusiones: el cuestionario POIBA-¿Cómo nos movemos? es una opción para evaluar la actividad física de escolares en el contexto latinoamericano. Los ítems sobre actividad física de transporte, en el ámbito escolar y deportivo, tuvieron los mayores índices de reproducibilidad.

Introduction: Reproducible instruments measuring physical activity and sedentary behaviors are a priority for monitoring and promoting healthy lifestyles for boys and girls. This study evaluated the test-retest reproducibility of the "Prevención de la Obesidad Infantil en Barcelona (Childhood Obesity Prevention in Barcelona) [POIBA]-How do we move?" questionnaire in Colombian school children. Materials and methods: One hundred twenty-five third-grade primary students from a public educational institution in Colombia participated in the "POIBA-How do we move?" questionnaire, which was conducted twice. The survey measured physical activity during travel to and from school, school hours (physical education classes and recess), extracurricular activities (sports with a coach), and leisure time. To assess reproducibility, categorical questions and questions with a quantitative scale were evaluated using kappa and weighted kappa indices and an intraclass correlation coefficient with a mixed-effects model. Results: In the questions about physical activity at school and sports practice, kappas higher than 0.70 predominated. The questions about commuting to and from school had kappa coefficients close to 0.90. The kappa coefficients for the screen-time questions were around 0.5, and the intraclass correlation coefficients for questions about going to bed and getting up were between 0.40 and 0.72. Conclusions: The "POIBA-How do we move?" questionnaire is a valuable tool for evaluating the physical activity of school children in a Latin American context. The questions concerning physical activity during commuting to and from school, school hours, and sports environment had the highest reproducibility indices.

Predictors of perceived barriers to physical activity in the general adult population: a cross-sectional study.

BACKGROUND: The perception of personal barriers to physical activity varies according to the sociodemographic characteristics of individuals. OBJECTIVE: To determine the predictors of the perception of barriers to physical activity in the adult population. METHOD: A cross-sectional study with 1066 adult women and 1036 adult men. The sociodemographic variables (age, gender, marital status, socioeconomic level, level of education), the perception of barriers that do not allow performance of physical activity (i.e. lack of time, social support, energy, motivation, skill, resources, and fear of injury during practice); and the level of physical activity through the International Physical Activity Questionnaire in its short-form version were evaluated. RESULTS: Individuals from low socioeconomic level (1 and 2) have higher risks of perceiving barriers such as lack of motivation [OR 1.76 (95% CI (1.4-2.1))] and lack of resources [OR 1.37 (95% CI (1.1-1.6))]; individuals with partners did not perceive the lack of social support [OR 0.29 (95% CI (0.2-0.4))] and lack of motivation [OR 0.54 (95% CI (0.4-0.7))] as barriers to physical activity. Individuals with low schooling perceived lack of social support [OR 3.81 (95% CI (3-4.7))], lack of resources [OR 2.78 (95% CI (2.2-3.3))], and fear of injury [OR 2.70 (95% CI (2.2-3.3))] as barrier to physical activity. CONCLUSION: Factors such as socioeconomic level, marital status, level of education, and self-perception of health are predictors of barriers to physical activity.

[Determinants of psychomotor performance in schoolchildren from Barranquilla, Colombia]. / Determinantes del desempeño psicomotor en escolares de Barranquilla, Colombia.

OBJECTIVE: To establish the prevalence of the psychomotor profile in children aged four to eight years attending the schools of the North Historical Center of Barranquilla, Colombia. METHOD: A cross-sectional descriptive study was conducted in 755 students from public and private schools aged between 4 and 8 years. The motor profile was measured by Da Fonseca Psychomotor Battery. RESULTS: An increased risk for apraxic-dyspraxic performance of the global praxis subfactor was observed in schoolchildren aged four to five years [OR 4.8; 95 % CI; 3.3-7.1] who study in public schools [OR 4.4; 95 % CI; 2.7-7.3], in those classified in the socioeconomic in strata 1, 2 and 3 [OR 2.4; 95 % CI; 1.5-3.9], and in those with an increased weight [OR 2; 95 % CI; 1.2-3.3]. The highest risk for apraxic-dyspraxic performance correlated to public school students [OR 1.9; 95% CI; 1.3-2.8] aged between four and five [OR 3.7; 95 % CI; 2.7-5.3]. The apraxic-dyspraxic performance in the structuring of the temporal space subfactor was higher in girls [OR 1.6; 95 % CI; 1.1- 2.2], in schoolchildren aged four to five [OR 4.8; 95 % CI; 3.3-7.1], in students of public schools [OR 1.9; 95 % CI; 2.7- 5.3], and in children classified in the socioeconomic strata 1, 2 and 3 [OR 1.6; 95 % CI; 1.1-2.7]. CONCLUSIONS: Determinants such as studying in public schools, nutritional status, gender and socioeconomic stratum are related to motor performance in students.

RESUMEN Objetivo Determinar los cambios en la práctica de actividad física durante la pandemia por COVID-19 en sujetos adultos. Métodos Estudio de corte transversal en 812 adultos de la región caribe colombiana. Se aplicó una encuesta vía telefónica, la cual registró: edad, sexo, nivel educativo y estrato socioeconómico; a su vez, se aplicó el Cuestionario de Intención hacia la actividad física de Prochaska y Marcus para medir las etapas de cambio hacia la actividad física. Se indagó sobre el tiempo sentado al día frente a pantallas como televisión, computador y celular. Las mediciones se realizaron entre los meses mayo y julio de 2020. Se realizó una regresión logística binaria para determinar la relación entre los factores individuales y la práctica de actividad física durante la pandemia. Resultados La proporción de personas que se categorizan en las tres primeras etapas de cambio aumentó de 65% en la medición antes de pandemia a 74,4% después de 4 meses de aislamiento social (p=0,0001). El promedio de horas al día en la población general frente al TV es de 2,7±2 horas; ante celulares, es de 3,8±2,8 horas, y 2,4±2,7 horas frente al computador. Las mujeres tuvieron mayor riesgo de no práctica de actividad física [OR 1,9 (IC 95% 1,4-2,7)], junto con las personas de nivel educativo bajo [OR 1,7 (IC 95% 1,2-2,4)] y las de edad mayor [OR 1,7 (IC 95% 1,3-2,4)]. Conclusión La pandemia por COVID-19 ha incrementado la inactividad física y los comportamientos sedentarios, los cuales varían según las características individuales.

ABSTRACT Objective To determine the changes in the practice of physical activity during the COVID-19 pandemic in adult subjects. Methods Cross-sectional study in 812 adults from the Colombian Caribbean region. A survey was applied by telephone that measured age, sex, educational level and socioeconomic status; likewise, the Prochaska and Marcus Physical Activity Intention Questionnaire to measure stages of change towards physical activity was applied. The time spent sitting each day in front of screens such as television, computer, and cellphone was investigated. Measurements were made throughout the months of May to July 2020. A binary logistic regression was performed to determine the relationship between individual factors and the practice of physical activity during the pandemic. Results The proportion of people who are categorized in the first three stages of change increased from 65% in the measurement before the pandemic to 74,4% after 4 months of social isolation (p=0,0001). The average hours a day in front of the TV for the general population is 2,7±2 hours; 3,8±2,8 hours in front of cellphones, and 2,4±2,7 hours in front of the computer. Women had a higher risk of not practicing physical activity [OR 1,9 (95% CI 1,4-2,7)], alongside people with a low educational level [OR 1,7 (95% CI 1,2-2,4)], and elderly people [OR 1,7 (95% CI 1,3-2,4)]. Conclusion The COVID-19 pandemic has increased physical inactivity and sedentary behaviors, which vary according to individual characteristics.

Condición física funcional de los adultos mayores en dos ciudades colombianas / Functional Physical Condition of Elderly Adults in Two Colombian Cities / Condição física funcional de idosos em duas cidades colombianas

Introducción: la optimización de la condición física en el adulto mayor disminuye los efectos del proceso de envejecimiento y las malas condiciones de vida en general. El objetivo es comparar la condición física funcional de adultos mayores en dos ciudades colombianas según variables sociodemográficas. Materiales y métodos: estudio de corte transversal en 428 adultos mayores asistentes a centros de atención al adulto mayor. Se indagaron características sociodemográficas. La condición física funcional se evaluó mediante la batería Senior Fitness. Se realizó una regresión logística bivariada estimando los odds ratio y su respectivo intervalo de confianza del 95 %. Resultados: los adultos mayores que viven en Tunja tuvieron mejores resultados, según la batería Senior Fitness, comparados con los de Barranquilla, tanto para hombres como para mujeres. En Tunja, las personas con edades entre 75 y 90 años tienen mayor riesgo de deficiencias en la resistencia aeróbica (or: 2.2; ic 95 %: 1.1-4.3). Se observa mayor probabilidad de disminución de la fuerza en miembros inferiores (or: 4.3; ic 95 %: 1.9-9.6), miembros superiores (or: 2.6; ic 95 %: 1.2-5.3) y de alteraciones del equilibrio (or: 2.1; ic 95 %: 1.1-4) en las personas que pertenecen al régimen subsidiado.

Introduction: Optimization of physical condition in the elderly reduces, in general, the effects of aging and poor living conditions. The objective was to compare, using sociodemographic variables, the func-tional physical condition of older adults in two Colombian cities. Materials and Methods: A cross-sec-tional study was carried out, in both cities, of 428 older adults who attended elderly care centers. Their sociodemographic characteristics were investigated. Functional physical condition was evaluated by way of the Senior Fitness battery. A bivariate logistic regression was performed to estimate odds ratios and 95% confidence intervals. Results: For both men and women, according to the Senior Fitness battery, elderly living in Tunja had better results than those in Barranquilla. In Tunja, people belonging to the subsidized regime, and between 75 and 90 years old, had a greater risk of deficiencies in aerobic resis-tance (or: 2.2; ci 95%: 1.1­4.3), and a higher probability of decreasing strength in the lower limbs (or: 4.3; ci 95%: 1.9­9.6), upper limbs (or: 2.6; ci 95%: 1.2­5.3), and balance disturbances (or: 2.1; ci 95%: 1.1­4). In Barranquilla, the probability of a high body mass index was higher in women than in men (or: 2.2; ci95%: 1.1­4.4) and those who were not married (or: 2.6; ci 95%: 1.2­5.6). Conclusion: The similarities and differences found among the subjects of the two cities raise questions that must be addressed through experimental studies

Introdução: a otimização da condição física em idosos permite reduzir os efeitos do processo de envelhe-cimento e as precárias condições de vida em geral. O objetivo é comparar a condição física funcional de idosos em duas cidades colombianas segundo variáveis sociodemográficas. Materiais e métodos: estudo transversal com 428 idosos atendidos em Centros de Atenção ao Idoso das duas cidades. As caracterís-ticas sociodemográficas foram investigadas. A condição física funcional foi avaliada por meio da bate-ria Senior Fitness. Foi realizada regressão logística bivariada estimando o Odds Ratio e seu respectivo intervalo de confiança de 95%. Resultados: os idosos residentes em Tunja tiveram melhores resultados de acordo com a bateria Senior Fitness em comparação com os residentes de Barranquilla tanto para homens quanto para mulheres; em Tunja, pessoas com idades entre 75 e 90 anos têm um risco maior de deficiências na resistência aeróbia (or: 2,2; ic 95%: 1,1-4,3), se observa uma maior probabilidade de diminuição da força nos membros inferiores (or: 4,3; ic 95%: 1,9-9,6), membros superiores (or: 2,6; ic 95%: 1,2-5,3) e alterações de equilíbrio (or: 2,1; ic 95%: 1,1-4) em pessoas que pertencem ao regime subsidiado. Em Barranquilla, a probabilidade de um imc elevado é maior nas mulheres do que nos homens (or: 2,2; ic 95%: 1,1-4,4) e naqueles que não têm companheiro (or: 2,6; ic 95%: 1,2-5,6).

Restrictions on persons with disabilities for participating in family and community activities / Restricciones en personas con discapacidad para su participación en actividades familiares y comunitarias

ABSTRACT Objective To identify the influence of functional impairments and limitations activities for persons with disabilities to particípate in family and community activities. Methods This is a cross-sectional study with 4 044 persons with disabilities, selected using probabilistic sampling and a door-to-door active search model in 5 towns in the District of Barranquilla. The data were processed with univariate analysis and bivariate analysis to determine the relationship between the study variables. Results 55.9% of the population were males, 41.6% were between 15 and 44 years of age, and 92.9% belonged to the lower socioeconomic stratum. 82.9% reported mobility limitations and 99% reported barriers to access non-formal learning activities, 98.6% to access public activities, and 97.5% to access productive activities. Individuals with that a lower limitation in exercising the power of reason, particularly thinking, can increase participation in activities with family and friends (OR, 0.8; 95% CI, 0.6-0.9), with the community (OR, 0.7; 95% CI, 0.6-0.9), religious or spiritual activities (OR, 0.8; 95% CI, 0.7-0.9). Conclusions There is a directly proportional relationship between structural impairment with the development of dependency and limited family, social, and work participation in the persons with disabilities.

[Knowledge, attitudes and practice regarding dengue in a neighborhood forming part of the city of Cartagena]. / Conocimientos, actitudes y prácticas sobre Dengue en un barrio de la ciudad de Cartagena de Indias.

OBJECTIVE: Identifying attitudes, practice and knowledge regarding dengue in a neighborhood of the city of Cartagena. METHODS: This was a cross-sectional study of 870 people living in a neighborhood in the south-eastern part of Cartagena. Probabilistic, randomized, three-staged sampling was used; it was intended to ascertain attitudes, practice and knowledge about dengue. The Stata statistics package (version 11.1) was used for analyzing the data to determine the absolute and relative frequency for each variable studied. RESULTS: It was found that 93.7 % of those surveyed knew about the disease; although 49.7 % did not know what the causal agent of the disease was, 80.5 % of those surveyed did express an interest. In receiving health education classes. 60.1 % of the population surveyed here stored water in their homes and 73.8 % used tanks as containers. 24.8 % of those surveyed stated that they avoided having/using stagnant water. CONCLUSIONS: The residents confirmed the high incidence of dengue cases reported by the district health department. Knowledge about dengue was limited; risky practices favoring the disease's development were adopted, but an attitude towards controlling this issue was evident. Changes in current behavior patterns must thus be promoted in the community and also regarding how prevention and control programs are being carried out.

Actividad física y calidad de vida en personas con enfermedad renal crónica / Association of physical activity with quality of life in patients with chronic kidney disease

Background: Physical activity may improve quality of life in patients with chronic kidney disease. Aim: To assess the relationship between physical activity and quality of life in patients with Chronic Kidney Disease. Material and Methods: The Kidney Disease Quality of Life-36 (KDQOL-36) and the International Physical Activity questionnaire were answered by 130 patients with chronic kidney disease (74 women, 80 receiving renal substitution therapy). Sociodemographic variables were recorded. Results: Patients on renal substitution therapy with a time lapse since diagnosis of 0 to 6 months had higher levels of physical activity than those with longer time lapses (51.4 ± 12.5 and 34.6 ± 8.1 minutes respectively). Disease burden scores were lower among patients with renal substitution therapy. There was a direct correlation between levels of vigorous and moderate physical activity and the physical functioning dimension in the quality of life questionnaire for patients with more than 19 months of disease. The dimension general physical health was significantly associated with physical activity in women and patients with 7 to 18 months of diagnosis. The dimension disease burden was associated with physical activity in women, patients not receiving substitution therapy and those with 7 to 18 months of diagnosis. Conclusions: Moderate and vigorous physical activity is directly related to the dimensions physical functioning, the general perception of physical health and inversely related with the dimension burden of disease.

Physical fitness, musculoskeletal disorders and body mass index in transport drivers from Barranquilla, Colombia / Condición física y molestias osteomusculares según el índice de masa corporal de conductores de transporte urbano de Barranquilla, Colombia

Abstract Introduction: Sedentary work activities in urban transport drivers are associated with overweight and obesity, an increase in musculoskeletal discomfort related to work and a decrease in physical fitness. Objective: To determine physical fitness and musculoskeletal discomfort in urban transport drivers from Barranquilla, Colombia, based on their body mass index (BMI). Material and Methods: Cross-sectional study conducted in 231 urban transport drivers. Healthy physical fitness and presence of musculoskeletal symptoms were measured using the AFISAL-INEFC test battery and the Nordic Questionnaire developed by Kuorinka, respectively. Results: There were significant differences between drivers with normal BMI and overweight/obese drivers in abdominal strength and endurance (21.4±8.9 vs. 19.6±8.8 stooped, p=0.04), flexibility (36.1±7.3 cm vs. 33.6±7.1 cm, p=0.02), and aerobic capacity (1537.5±704.8 meters vs. 1249.1±346.6 meters, p=0.0001). Increased frequency ofmusculoskeletal discomfort was observed in subjects with BMI >25 kg/m2. Conclusions: Overweight and obesity are associated with poor physical fitness and the perception of musculoskeletal discomfort, which has negative implications for the personal and occupational well-being of these workers, generating a burden for companies and the Colombian health system.

Se observó mayor frecuencia de molestias musculoesqueléticas en los sujetos con IMC >25 kg/m2. Conclusiones. El sobrepeso y la obesidad están relacionados con la baja condición física y la percepción de molestias osteomusculares, lo cual tiene implicaciones negativas en el bienestar personal y laboral de estos trabajadores y constituye una carga para las empresas y el sistema de salud.

Efectos agudos del ejercicio resistido en la lipemia postprandial de mujeres postmenopáusicas con sobrepeso / Acute effects of resistance training on postprandial lipemia in overweight postmenopausal women

Resumen Introducción. La magnitud de la lipemia postprandial es un indicador de riesgo cardiovascular, en especial en mujeres con actividad hormonal reducida. Los ejercicios resistidos (ER) podrían ser un factor que influencie las concentraciones de lípidos después de consumir alimentos. Objetivo. Determinar los efectos agudos sobre la lipemia postprandial de mujeres postmenopáusicas que tiene la realización de sesiones de ER de alto y bajo volumen, en comparación a un grupo control. Materiales y métodos. Después de una evaluación inicial (antropometría, perfil lipídico y fitness muscular), 32 mujeres fueron divididas aleatoriamente en tres grupos: uno con ER de alto volumen (n=11), otro con ER de bajo volumen (n=11) y un grupo control sin ER (n=10). 12 horas después de los ejercicios se suministró un compuesto nutricional hiperlipídico y se analizó la lipemia postprandial cada hora durante 5 horas. Resultados. Los diferentes volúmenes de ER no redujeron de manera importante los marcadores lipémicos (colesterol total, triglicéridos, LDL y VLDL) (p>0.05) ni aumentaron las concentraciones plasmáticas de HDL (p>0.05). Conclusiones. Las sesiones de ER no afectaron los marcadores lipémicos postprandiales, aunque sí mostraron resultados clínicos relevantes en los grupos experimentales (reducción de LDL-VLDL y aumento de HDL en momentos específicos).

Abstract Introduction: The magnitude of postprandial lipemia is an indicator of cardiovascular risk, especially in women with reduced hormonal activity. Resistance training (RT) may be a factor influencing lipid concentrations after eating. Objective: To determine the acute effects of high and low volume RT sessions on postprandial lipemia in postmenopausal women compared to a control group. Materials and methods: After an initial assessment (anthropometry, lipid profile and muscle fitness), 32 women were randomly divided into three groups: one with high volume of RT (n=11), another with low volume of RT (n=11) and a control group without RT (n=10). 12 hours after the completion of the training, a hyperlipidic nutritional compound was administered and postprandial lipemia was analyzed every hour for 5 hours. Results: The different RT volumes did not significantly reduce lipemic markers (total cholesterol, triglycerides, LDL and VLDL) (p>0.05) nor did they increase plasma HDL concentrations (p>0.05). Conclusions: RT sessions did not affect postprandial lipemic markers, although they did show relevant clinical results in the experimental groups (reduction of LDL-VLDL and increase of HDL at specific times).

[Elderly people's level of participation in social and recreational activities in Barranquilla, Colombia]. / Nivel de participación en actividades sociales y recreativas de personas mayores en Barranquilla, Colombia.

OBJECTIVE: Determining elderly people's level of participation in social and recreational activities in Barranquilla, Colombia. METHODS: This was a descriptive cross-sectional study involving 469 elderly people; a basic activities of daily living scale, which had been adapted to the ongoing activities being carried out in the pertinent scenarios, was used for evaluating their level of participation in social and recreational activities. Bivariate analysis was used for estimating the relationship between level of participation and age-range and coexistence, using OR and χ2 tests. RESULTS: The scale categorized 40.9 % of the subjects as having low participation and only 20.2 % as actively and voluntarily participating in the activities being offered. There was an increased risk of non-participation in social and recreational activities regarding adults being over 80 years of age (OR 3.3: (2.2-4.9) 95 % CI) and those living alone (OR 1.75: (1.09-2.82) 95 % CI). CONCLUSION: A clear trend towards less participation was shown as aged increased; this is why social isolation becomes a risk factor for this group of people's quality of life. It is recommended that social networks promoting the elderly's health and quality of life should thus be strengthened.
