Factores de riesgo relacionados con los hábitos de vida en pacientes con patología osteomuscular / Risk factors related with lifestyle in patients with musculoskeletal disorders

Introducción: las enfermedades osteomusculares (EOM) engloban una serie de patologías discapacitantes con alta incidencia y prevalencia, representando un alto costo económico y social. Es fundamental su prevención, por lo que es de gran interés determinar factores de riesgo modificables, como son los relacionados con los hábitos de vida. Métodos: se realizó un estudio descriptivo y trasversal en 91 pacientes seleccionados mediante muestreo aleatorio sistemático y que fueron distribuidos en tres grupos experimentales según la causa y evolución de su EOM (cervicalgia, gonalgia y lumbalgia). Se realizó una medición biométrica, evaluación nutricional, de la actividad física y laboral, del balance muscular y del estado oxidativo. Resultados: el sexo femenino es el más afectado por la presencia de lesiones osteomusculares como cervicalgia y lumbalgia. En conjunto, la mayor parte de los pacientes (67,4%) tiene normopeso, el 24,41% sobrepeso y tan solo un 8,1% obesidad tipo I. Los pacientes con cervicalgia son el grupo que realiza menos actividad física y peor balance muscular presentan. El estrés oxidativo fue superior en pacientes con gonalgia que en los otros grupos. Con respecto a la dieta consumida, se observan diferencias entre grupos experimentales en el contenido mineral (Zn, Mn, Se y I) y vitamínico (folato y ácido ascórbico). Conclusiones: la ingesta de colecalciferol y vitaminas A y D es inferior a las recomendadas en todos los sujetos, lo que favorece la dolencia muscular. La ingesta de folato está por debajo de las recomendaciones, incidiendo en la mayor susceptibilidad al estrés oxidativo. La obesidad y estrés oxidativo se relacionan con la prevalencia de los diferentes tipos de EOM estudiados (AU)

Background: Musculoskeletal disorders (MSDs) encompass a series of debilitating diseases with high incidence and prevalence, representing a high economic and social cost. Prevention is crucial, so is of great interest to determine modifiable risk factors, such as those related to lifestyle. Methods: A descriptive cross-sectional study was performed in 91 patients selected by systematic random sampling and were divided into three experimental groups according to the cause and evolution of its MSD (neck pain, knee pain and back pain). A biometric measurement, nutritional assessment, physical and occupational activity, muscle balance and oxidative status was performed. Results: The female is the most affected gender by the presence of musculoskeletal injuries such as neck pain and back pain. Overall, most patients (67.4%) had normal weight, overweight 24.41% and only 8.1% were obese type I. Patients with neck pain are the group doing less physical activity and worse muscular balance present. Oxidative stress was higher in patients with knee pain than in the other groups. Regarding the consumed diet, differences between experimental groups on the mineral content (Zn, Mn, Se and I) and vitamins (folate and ascorbic acid) are observed. Conclusions: Cholecalciferol intake and vitamins A and D is less than those recommended in all subjects, which promotes muscle disease. Folate intake was below recommendations, increasing susceptibility to oxidative stress. Obesity and oxidative stress related to the prevalence of the different types of MSDs studied (AU)

The effects of black soybean (Glycine max var.) on chronic cervical pain of sedentary office workers in a northern Chinese population.

Chronic cervical pain is a common symptom of sedentary office workers. Black soybean (Glycine max var.) has rich necessary nutrients for the therapy of chronic pain. Thus, it may ease chronic cervical pain. To prove our claim, 260 sedentary office workers with chronic pain were recruited and they consumed the defined diets at breakfast, lunch, and dinner with 1 g, 5 g and 10 g (3 g, 15 g, 30 g daily) cooked black soybean for 24 weeks. Visual analog scale (VAS), neck disability index (NDI) pain scores and short-form 36 (SF-36) health survey questionnaires were applied in the study. The levels of N-methyl-D-aspartate receptors (NMDAR) were measured. The VAS and NDI pain scores reduced and SF-36 scores increased in a 15 or 30 g black soybean daily group compared with a 3 g black soybean daily group after a 24-week therapy (P < 0.05). The 30 g black soybean daily group was better than the 15 g black soybean daily group in relieving chronic cervical pain of sedentary office workers (p < 0.05). The levels of NMDAR were lower in the 15 or 30 black soybean daily group than those in the 3 g black soybean daily group (P < 0.05). Black soybean can ameliorate chronic cervical pain by down-regulating the levels of NMDAR.
