ABSTRACT
Introducción: el sol constituye la fuente principal de vitamina D, las últimas décadas se han caracterizado por una menor exposición al sol de la población general, lo cual ha posibilitado que el déficit de vitamina D reaparezca como un problema de salud mundial. Esta situación ha generado grandes controversias internacionales sobre el uso de suplementos de vitamina D en la edad pediátrica. Objetivo: reflexionar sobre las recomendaciones internacionales de suplementación con vitamina D en las edades pediátricas, ajustándolas al contexto cubano. Método: revisión documental. Se utilizaron motores de búsqueda (Google Académico, Springer Link, Microsoft Academic y SciELO - Scientific Electronic Library Online), y se emplearon las bases de datos disponibles en la Biblioteca Virtual de Salud, se revisaron evidencias científicas y se realizaron recomendaciones basadas en las mismas. Conclusiones: existen factores que llevan implícito un incremento del riesgo potencial de déficit de vitamina D. En Cuba se destacan la actualización de las medidas de fotoprotección para las edades pediátricas, la prevalencia de fototipos altos y el incremento de la obesidad en la población infantil. Se realizaron 9 recomendaciones para garantizar un aporte adecuado de vitamina D a los niños y adolescentes cubanos, el equivalente a 400 UI de vitamina D para menores de un año y 600 UI para los mayores de esa edad que pertenezcan a grupos de riesgo para esta hipovitaminosis(AU)
Introduction: The sun is the main source of vitamin D. The last decades have been characterized by a lower exposure to the sun by the general population, what has caused the recurrence of vitamin D deficit as a world health problem. This situation has given rise to international controversies on the use of vitamin D supplements in children. Objective: To reflect on the international recommendations about the use of vitamin D supplements in children, meeting the Cuban context. Method: A bibliographic review was carried out, using the search engines Scholar Google, Springer Link, Microsoft Academic and SciELO - Scientific Electronic Library Online, as well as databases available at the Health Virtual Library. Scientific evidences were checked and recommendations based on them were made. Conclusions: There are factors that have an implicit increasing risk of vitamin D deficit. In Cuba some important features stand out, as the updating of photoprotection in children, the prevalence of high phototypes and the increase of obesity in the child population. Nine recommendations were carried out to guarantee an adequate contribution of vitamin D to the Cuban children and adolescents, an equivalent of 400 IU of vitamin D for children younger tan one year and 600 IU for the older ones who belong to risk groups for this type of hypovitaminosis(AU)

In tropical poultry-producing countries, poultry houses usually have little environmental control. This study investigated the effect of dietary vitamin D on the incidence of leg abnormalities of a fast-growing broiler strain reared under harsh conditions. In this study, 300 one-day-old male broilers were distributed in two treatments with three replicates of 50 birds each. One group was fed a placebo and the other group was fed 25-hydroxycholecalciferol (25-OH-D3) in a soluble form. The environmental variables were weekly recorded during until birds were 49 days old. Birds were weekly gait scored, and their walking speed and vertical force while walking were assessed. Post-mortem examination was performed and skeletal lesions were assessed. Control birds presented more leg problems than those that ingested 25-OH-D3. These results suggest that dietary vitamin D is effective in decreasing the severity of lameness by reducing tibial dyschondroplasia and other leg abnormalities.(AU)
