Background. The focus of this study is to determine if a correlation exists between knowing the consequences that may arise from obesity and the level of a person’s physical activity. Methods. A cross-sectional study performed on a group of 215 students was conducted in 2013 and 2014. The students were selected by convenience sampling at a university in Lima, Peru. The level of physical activity was measured using the International Physical Activity Questionnaire (IPAQ), and the knowledge that each student had about the consequences of obesity was assessed using the Obesity Risk Knowledge-10 scale (ORK-10). Each student was also asked to record the source where they obtained what information they knew. Results. The median age of the participants was 20 (interquartile range=4), and 63% of the participants were female. According to the IPAQ, 53.9% of the participants recorded high levels of physical activity, 35.4% recorded moderate levels, and 10.7%, recorded low levels. While a low correlation between the ORK- 10 score and the amount of METs/minute/week spent was found (rs=0,06), it was not significant (p=0.38). We found that people who were informed by the media or healthcare personnel achieved higher scores at the ORK-10 scale than those who used other sources of information (p<0,05). Conclusions. There is a very low correlation between the knowledge about the consequences of obesity and a person’s level of physical activity. A multidisciplinary approach that includes all of the determinants of physical activity performance is necessary in order to attain changes in people’s behavior.

AbstractIntroducción. El objetivo del presente estudio es determinar si existe correlación entre los conocimientos sobre las consecuencias de la obesidad y el grado de actividad física de las personas. Métodos. Se realizó un estudio transversal analítico durante los años 2013 y 2014. Participaron 215 alumnos de pregrado seleccionados por conveniencia no relacionados a carreras del campo de la salud en una universidad de Lima, Perú. Se evaluó el grado de actividad física utilizando el International Physical Activity Questionnaire (IPAQ) y el nivel de conocimientos sobre consecuencias de la obesidad utilizando la escala Obesity Risk Knowledge-10 (ORK-10). También, se consignó las fuentes de información de donde obtuvieron el conocimiento para responder dicho cuestionario. Resultados. La mediana de edad fue 20 (rango intercuartílico=4) y 63% eran mujeres. De acuerdo al IPAQ, 53,9% realizaban actividad física alta, 35,4%, moderada y 10,7%, leve. Se encontró una correlación muy baja (rs=0,06) entre el puntaje del ORK-10 y la cantidad de equivalentes metabólicos/minuto consumidos por semana, pero no era significativa (p=0,38). Las personas informadas por medios de comunicación y por personal de salud obtuvieron mayores puntajes en el ORK- 10 que quienes se informaron por otras vías (p<0,05). Conclusiones. La correlación entre los conocimientos sobre consecuencias de la obesidad y el grado de actividad física es muy baja. Es necesario utilizar enfoques multidisciplinarios que incluyan todos los determinantes de la realización de actividad física para poder lograr cambios en la conducta de la población.

Assessment of Rehabilitation Infrastructure in PeruFuhs, Amy K.; LaGrone, Lacey N.; Moscoso Porras, Miguel G.; Rodríguez Castro, Manuel J.; Ecos Quispe, Rosa Lizbeth; Mock, Charles N. (W.B. Saunders, 2017-11)Objective: To assess rehabilitation infrastructure in Peru in terms of the World Health Organization (WHO) health systems building blocks. Design: Anonymous quantitative survey; questions were based on the WHO's Guidelines for Essential Trauma Care and rehabilitation professionals' input. Setting: Large public hospitals and referral centers and an online survey platform. Participants: Convenience sample of hospital personnel working in rehabilitation and neurology (N=239), recruited through existing contacts and professional societies. Interventions: Not applicable. Main Outcome Measures: Outcome measures were for 4 WHO domains: health workforce, health service delivery, essential medical products and technologies, and health information systems. Results: Regarding the domain of health workforce, 47% of physical therapists, 50% of occupational therapists, and 22% of physiatrists never see inpatients. Few reported rehabilitative nurses (15%) or prosthetist/orthotists (14%) at their hospitals. Even at the largest hospitals, most reported ≤3 occupational therapists (54%) and speech-language pathologists (70%). At hospitals without speech-language pathologists, physical therapists (49%) or nobody (34%) perform speech-language pathology roles. At hospitals without occupational therapists, physical therapists most commonly (59%) perform occupational therapy tasks. Alternate prosthetist/orthotist task performers are occupational therapists (26%), physical therapists (19%), and physicians (16%). Forty-four percent reported interdisciplinary collaboration. Regarding the domain of health services, the most frequent inpatient and outpatient rehabilitation barriers were referral delays (50%) and distance/transportation (39%), respectively. Regarding the domain of health information systems, 28% reported rehabilitation service data collection. Regarding the domain of essential medical products and technologies, electrophysical agents (88%), gyms (81%), and electromyography (76%) were most common; thickened liquids (19%), swallow studies (24%), and cognitive training tools (28%) were least frequent. Conclusions: Rehabilitation emphasis is on outpatient services, and there are comparatively adequate numbers of physical therapists and physiatrists relative to rehabilitation personnel. Financial barriers seem low for accessing existing services. There appear to be shortages of inpatient rehabilitation, specialized services, and interdisciplinary collaboration. These may be addressed by redistributing personnel and investing in education and equipment for specialized services. Further examination of task sharing's role in Peru's rehabilitation services is necessary to evaluate its potential to address deficiencies. © 2017 American Congress of Rehabilitation Medicine.
Modelo de Gestión del Portafolio Digital del nivel de Percepción sobre la Evaluación del Aprendizaje del EstudianteErika Nancy Castillo Pantoja; Raymundo Ibañez, Carlos Arturo (nternational Institute of Informatics and Systemics, IIIS, 2017-03)The digital management model portfolio emerges as an alternative for the evaluation of the learning that acts as support in the performance of the process of teaching and the continuous improvement of the students learning process, in the course thesis of the computing and systems engineering program, providing the opportunity for being the host of his own learning. The main feature of this tool is that allows the evidence management and the self-assessment of this learning involving cognitive and metacognitive processes leading to consider it one of the most important educational innovations in the university environment.
El perfil del consumidor peruano en el sector de bebidas no alchólicas (BNA)Cuya, María Laura; Buralli Valdez, Roberto; Sanchez Maltese, Alonso; Zevallos Dávila, Humberto (Universidad Peruana de Ciencias Aplicadas (UPC), 2017-02-18)This paper examines the effect of applying a product adaptation or tropicalization strategy, compared to the strategy of using global products with minimal adaptations, in the non - alcoholic beverages sector of the Peruvian market between 2010 and 1015. In this sense, it will analyze historical data of the performance of the brands competing in that market to determine which have been the ones that have had the best results during the analyzed period. Also the products offered by the brands studied will be analyzed to determine which offer products Adapted to the Peruvian market (tropicalized) and which offer global products (standardized). In this way it will be possible to determine which strategy has been the most effective to compete in the Peruvian market. Market studies and specialized press reports will also be consulted to complement and assist the analysis of the data studied. The data analyzed suggest that there is no clear relationship between the use of adaptation strategies or product standardization in the Peruvian soft drink market. Rather, the results suggest that the companies with the best results are adapting their brands to changes in the lifestyles of their consumers, and not those that make variations only when it refers to the flavors and varieties of beverages considered Popular in the target audience of the brand. For this reason, this essay concludes that the adaptation of non-alcoholic beverages must be understood as adapting beverages to meet the needs of consumers.
