RESUMO

Background: NutriNet-Salud Mexico is a digital health information system, e-epidemiology instrument, online, open and free, to recording and analysis the determinants of dietary habits and nutritional status of the Mexican population, for the prevention of overweight, obesity and noncommunicable diseases for the period 2018-2028. Objective: Describe the design, development and implementation of NutriNet-Salud Mexico from the French model NutriNet-Santé France 2008-2018. Method: NutriNet-Salud Mexico platform is the basis for the development of health information system for prospective cohort study, scheduled for a period of 10 years (2018-2028), with a dedicated website, and its development will enable to have multiple study populations within an initial set of five self-applicable questionnaires validated in Mexican population. Results: The information will enable to develop applied research, learn and monitor food contributions and nutritional status of the population, assess the impact of public health actions on feeding behavior and nutritional status, comparing populations between countries (Mexico, France, Belgium and Switzerland) and national institutes, universities and states. Conclusions: NutriNet-Salud Mexico will provide information for assist in research and public action, especially to guide public policies on nutrition Mexico. The scientific elements will make appropriate nutritional recommendations to different populations and access to a representative nominal population sample with low-cost, in real-time, and with dual approach to e-epidemiology: cohort study to identify causality and cross-sectional studies (descriptive research, monitoring and evaluation).

Introducción: NutriNet-Salud México es un sistema de información en salud digital, instrumento de e-epidemiología, en línea, abierto y gratuito, para el registro y el análisis de los factores determinantes de los hábitos alimentarios y el estado nutricional de la población mexicana, para la prevención del sobrepeso, la obesidad y las enfermedades crónicas no transmisibles para el período 2018-2028. Objetivo: Describir el diseño, el desarrollo y la implementación de NutriNet-Salud México a partir del modelo francés NutriNet-Santé France 2008-2018. Método: La plataforma NutriNet-Salud México es la base digital para el desarrollo de un sistema de información en salud ­para un estudio de cohorte prospectivo programado para 10 años (2018-2028)­ con un sitio web dedicado cuyo desarrollo permite tener varias poblaciones de estudio que responden un conjunto inicial de cinco cuestionarios autoaplicables validados en población mexicana. Resultados: La información obtenida permitirá desarrollar investigación aplicada, conocer y vigilar los aportes alimentarios y el estado nutricional de la población, evaluar el impacto de acciones de salud pública sobre el comportamiento alimentario y el estado nutricional, y comparar poblaciones entre países (México, Francia, Bélgica y Suiza) e institutos nacionales, universidades y Estados. Conclusiones: NutriNet-Salud México permitirá coadyuvar en investigación y acción pública, especialmente en la orientación de políticas públicas de México en materia de nutrición. Los elementos científicos aportarán recomendaciones nutricionales adecuadas a diferentes poblaciones, y permitirán acceder a una representativa muestra poblacional nominal a bajo costo y en tiempo real con doble abordaje de e-epidemiología: estudio de cohorte para identificar causalidad y estudios transversales periódicos (investigación descriptiva, monitoreo y evaluación).

RESUMO

An online consultation tool, the Sexually Transmitted Diseases Clinical Consultation Network is a new resource for sexually transmitted disease clinicians and clinic managers. An initial evaluation shows that most requests (29%) were from medical doctors, followed by nurse practitioners (22%). Syphilis queries comprised 39% of consults followed by gonorrhea (12%) and chlamydia (11%).

RESUMO

The planning, design and implementation stages of a computer-based approach to the indexing of the biomedical bibliography in Mexico are described; a proposal for an index to be set up at Mexico's National Health Information and Documentation Centre (CENIDS). Factors such as Mexico's biomedical information production; local information needs; and establishment of objectives/goals of the indexing system are described as relevant indicators to be considered at the planning stage. General computer and non-computer functions, as well as two possible alternatives to the design stage are proposed. A 'phase approach' implementation is also advised. Finally, several information management and organization factors are described as the benefits derived from this proposal; transference of national knowledge; current awareness services and international collaboration, among others.
