Resumen: Objetivo: determinar los valores séricos de la enzima lecitina colesterol aciltransferasa en un grupo de mujeres postmenopáusicas, y establecer su relación con factores asociados a riesgo cardiovascular. Materiales y métodos: estudio descriptivo transversal prospectivo, correlacional, que incluyó 56 mujeres postmenopáusicas en quienes se evaluaron variables antropométricas y bioquímicas (perfil lipídico y glicemia basal) asociadas a riesgo cardiovascular y se correlacionaron con las concentraciones séricas de lecitina colesterol aciltransferasa. Resultados: los valores séricos promedio de dicha enzima fueron 7,89 ± 1,26 μg/ml. Las mujeres con valores de índice de masa corporal superior a 25 tienen niveles séricos de lecitina colesterol aciltransferasa significativamente mayores que aquellas que tienen índice de masa corporal normal. No se observaron relaciones significativas entre los niveles de lecitina colesterol aciltransferasa y las variables bioquímicas evaluadas. Conclusiones: este trabajo es uno de los primeros que evalúa los niveles séricos de lecitina colesterol aciltransferasa en mujeres postmenopáusicas del Caribe colombiano. Se encontró una relación significativa entre los niveles séricos de lecitina colesterol aciltransferasa y los valores de índice de masa corporal elevados. Se requieren nuevos estudios para entender mejor la relación entre los niveles séricos de lecitina colesterol aciltransferasa y el riesgo cardiovascular en mujeres postmenopáusicas. Abstract: Objective: To determine the serum levels of lecithin cholesterol acyltransferase in a group of postmenopausal women and to establish their relationship with factors associated with cardiovascular risk. Materials and methods: A descriptive, correlational and cross-sectional study was performed that included 56 postmenopausal women. Anthropometric and biochemical (lipid profile and baseline blood glucose) variables associated with cardiovascular risk were measured, and were correlated with the serum concentrations of lecithin cholesterol acyltransferase. Results: The mean serum level of lecithin cholesterol acyltransferase was 7.89 ± 1.26 μg/ml. The women with a body mass index greater than 25 had significantly higher serum levels of the enzyme than those that had a normal body mass index. No significant relationships were observed between the levels of lecithin cholesterol acyltransferase and the biochemical variables evaluated. Conclusions: This study is one of the first that has evaluated the serum levels of lecithin cholesterol acyltransferase in postmenopausal women of the Colombian Caribbean. A significant relationship was found between the serum levels of lecithin cholesterol acyltransferase and elevated values of the body mass index. Further studies are required for a better understanding of the relationship between the serum levels of lecithin cholesterol acyltransferase and cardiovascular risk in postmenopausal women.

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. Resumen Introducción. Las actividades laborales sedentarias de los conductores de transporte urbano están asociadas a sobrepeso, obesidad, incremento de molestias osteomusculares relacionadas con el trabajo y disminución de la condición física. Objetivo. Determinar la condición física y las molestias osteomusculares de conductores de transporte urbano de Barranquilla, Colombia, según su índice de masa corporal (IMC). Materiales y métodos. Estudio transversal realizado en 231 conductores de transporte urbano. Se midió la condición física saludable y la presencia de síntomas musculoesqueléticos con la Batería AFISAL INEFC y el Cuestionario Nórdico de Kuorinka, respectivamente. Resultados. Existen diferencias significativas entre los conductores con IMC normal y aquellos con sobrepeso/obesidad en los valores de fuerza y resistencia abdominal (21.4±8.9 vs. 19.6±8.8 encorvadas, p=0.04), flexibilidad (36.1±7.3cm vs. 33.6±7.1cm, p=0.02) y capacidad aeróbica (1537.5±704.8m vs. 1249.1±346.6m, p=0.0001). 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.

Postmenopausal period disturbances are more frequently observed in women with unhealthy lifestyles, insufficient physical activity is related to increased cardiovascular risk (CVR). There is a lack of evidence-based information on physical activity in postmenopausal women and its relationship with CVR factors, including D vitamin serum levels. Objective: To determine the physical activity level in postmenopausal women from the Colombia Caribbean and establish relationships between the physical activity and biochemical and anthropometric CVR factors. Methods: A correlational descriptive study in which 183 postmenopausal women were linked for convenience sampling. Level of physical activity (International Physical Activity Questionnaire) and their relationships with anthropometric variables, blood pressure, lipid profile, glycemic and serum vitamin D were evaluated. Results: According to the physical activity, 82.5% of women were classified as inactive, 9.3% as insufficiently active and only 8.2% as physically active. Physical inactivity was significantly related to higher glucose, triglycerides, and total cholesterol serum levels (P

Background. Previous evidence suggests that metabolic disorders in postmenopausal women could be related with low serum vitamin D levels. For example, vitamin D deficiency has been associated with increased risk factors for cardiovascular disease (CVD), mainly those related with metabolic syndrome.Objective. To assess the relationship between the serum vitamin D (25-OH-D) levels and the metabolic syndrome markers in postmenopausal women.Methods. This descriptive and cross-sectional study was conducted in 183 postmenopausal women of four municipalities from Colombian Caribbean. The serum 25-OH-D levels and the anthropometric and biochemical markers were assessed and correlated with metabolic syndrome.Results. The average value of serum vitamin D (25-OH-D) was 26.34 ± 9.08 ng/mL, and 69.95% of the women had vitamin D levels 20 ng/mL) and 26.23% with deficiency (P=0.014).Conclusion. In the evaluated population in this study, vitamin D deficiency is related with low HDL cholesterol levels.

La actividad física hace referencia al movimiento corporal que genera gasto energético, su práctica frecuente mejora las funciones físicas y mentales; el transporte activo, las actividades cotidianas y la recreación corresponden a la forma más común de actividad física. En Colombia la mayor parte de la población es inactiva, los niños son más activos, pero esta condición disminuye con la edad, el porcentaje de universitarios que realizan actividad física es bajo, está práctica está condicionada por la motivación interna, la condición física, la disponibilidad de tiempo y el soporte social. El gusto por el deporte, el espíritu competitivo, el mejoramiento de la imagen corporal, el manejo del estrés y los beneficios para la salud son factores motivadores para la práctica de la actividad física en estudiantes universitarios; por otra parte la pereza, el miedo a lesionarse, la escases de escenarios deportivos y la inseguridad del entorno son las barreras más frecuentes para la realización de actividad física en esta población
