Challenges and Opportunities to Translate Global SUN Momentum into Action in Rural Mozambique.

Objectives: Globally, the SUN movement has contributed to increased discussion, commitment, and momentum around reducing malnutrition. There is, however, limited evidence on how to shape and sustain an enabling environment to scale up nutrition interventions. The objective was to document the challenges and opportunities to translate global SUN momentum into action to fight malnutrition in rural Mozambique. Methods: We systematically documented the processes involved in developing a stunting prevention program by the government of Mozambique and supported by the World Food Programme (WFP). We also interviewed WFP staff and other stakeholders to document challenges and opportunities for more effectively supporting an enabling environment for largescale stunting prevention programming. Results: Commitment to establishing stunting prevention programing required sensitization of national stakeholders to the individual and collective damage caused by stunting and the effectiveness of response options. Credible scientific data and technical expertise were paramount. A general national nutrition strategy was a prerequisite for designing stunting-specific programing. SUN movement advocacy facilitated governmental and stakeholder engagement and assisted in the local-level prioritization of stunting prevention programing. Stakeholders were more amenable to support program development when it aligned with the SUN movement. Nonetheless different stakeholders needed and wanted different information and audience-specific communication was critical; as was addressing sustainability from the initiation of design development process. Conclusions: The SUN movement facilitated the initiation of large scale stunting prevention programing in Mozambique. However, generating local ownership through use of local evidence, and expertise, and addressing local needs such as sustainability were critical.

Micronutrient Deficiencies in Pre-school Age Children and Women of Reproductive Age in Jordan.

Objectives: Jordan's 2010 National Micronutrient Survey assessed the prevalence and severity of anemia and micronutrient deficiencies in Jordanian women and children. Methods: A stratified multistage cluster sampling was used to establish a nationally representative household-based sample of Jordanian children (12 - 59 months) and non-pregnant women of reproductive age (15-49 years). Weighted descriptive statistics were used to calculate national prevalence and multivariate analyses were undertaken for the determination of risk factors of vitamin D deficiency Results: Anemia in children (hemoglobin < 110g/L) and women (hemoglobin < 120g/L) was a mild (17.0%) and moderate (30.6%) public health problem, respectively. Vitamin A deficiency (serum retinol < 0.70 umol/L) was prevalent in 18.3% of children and 4.8% of women. Vitamin D deficiency (25(OH)D3 < 11.0 ng/mL and < 12.0 ng/mL in children and women, respectively) was prevalent in 19.8% of children and 60.3% of women. Vitamin D deficiency was significantly more likely in women who routinely cover themselves with a scarf compared to those women who do not cover. In urban areas, children whose mothers were vitamin D deficient were more likely to be vitamin D deficient than children whose mothers were not deficient. Conclusions: With the exception of vitamin A, a higher burden of micronutrient deficiencies is seen in Jordanian women than children. Vitamin D deficiency in women is the most prevalent micronutrient deficiency in Jordan with approximately 3 out of 5 women being deficient.

An evaluation of a global vitamin and mineral nutrition surveillance system / Evaluación de un sistema global de vigilancia nutricional sobre vitaminas y minerales

Evaluation at all levels is a fundamental function at World Health Organization (WHO). Evaluation of public health surveillance systems is essential to ensure that problems of public health importance are monitored efficiently and effectively. The WHO's Vitamin and Mineral Nutrition Information System (VMNIS) was evaluated from the perspective of public health surveillance and informatics. Steps included: engaging the stakeholders of the evaluation; describing the surveillance system; focusing the evaluation design; gathering credible evidence regarding system performance; justifying and stating conclusions and recommendations, and sharing lessons learned from the evaluation. Following this assessment, WHO has begun major efforts to upgrade and expand the VMNIS and now the database is more flexible and efficient. The database evaluation summarized in this paper provides a good example of how public health evaluation frameworks can lead to improved surveillance and enhanced information systems, thus making progress toward the ultimate goal of improving public health.

La evaluación en todos los niveles es una función fundamental en la Organización Mundial de la Salud (OMS). La evaluación de los sistemas de vigilancia epidemiológica es esencial para asegurar que los problemas de importancia para la salud pública sean monitorizados de manera eficiente y efectiva. El Sistema de Información Nutricional sobre Vitaminas y Minerales (VMNIS, por sus siglas en inglés) se evaluó desde la perspectiva de sistema de vigilancia e informática en salud pública. Los pasos incluyeron: el involucramiento de las partes interesadas en la evaluación, la descripción del sistema de vigilancia, el enfoque del diseño para la evaluación, la recopilación de pruebas fiables sobre el rendimiento del sistema, la justificación y desarrollo de conclusiones y recomendaciones, y la diseminación de las lecciones aprendidas de la evaluación. Después de este proceso, la OMS inició importantes esfuerzos para mejorar y ampliar el Sistema de Información Nutricional sobre Vitaminas y Minerales para lograr una base de datos más flexible y eficiente. Este artículo resume la evaluación de esta base de datos para documentar un buen ejemplo de cómo los marcos de evaluación en salud pública pueden llevar a mejorar la información en los sistemas de vigilancia contribuyendo de esta manera al objetivo final de mejorar la salud pública.

Impact of a school-based intervention program on obesity risk factors in Mexican children / Impacto de un programa de intervención en escuelas para la prevención de factores de riesgo de la obesidad en niños mexicanos

Objective. To evaluate the impact of an 18-month school obesity prevention intervention on the health behaviors of 4th and 5th grade students based on ecological principles and formative research conducted in Mexico. Materials and methods. A Randomized Control Trial (RCT), design was used to assign 27 schools to one of three conditions: basic or plus interventions and control. School environment measures, children's eating and physical activity behaviors, and body mass index were assessed four times over a 2-year period in a sample of 830 students. Results. In the intervention schools, the availability of healthy foods increased with a concomitant decrease in unhealthy food availability. Food intake showed the same trend. In the intervention schools, children did not engage in more moderate to vigorous physical activity (MVPA) in physical education (PE) class or recess but increased steps taken. Obesity prevalence did not change. Conclusion. The intervention improved the school food environment and child healthy behaviors.

Objetivo. Evaluar el impacto de una intervención de 18 meses para la prevención de obesidad en escolares de 4o y 5o grados basada en el modelo ecológico en conductas saludables en México. Material y métodos. Diseño experimental para asignar 27 escuelas a uno de los tres tratamientos: intervenciones básicas, intervenciones plus y control. Se midió el impacto en el ambiente escolar, la alimentación y la actividad física e índice de masa corporal en niños. La evaluación se llevó a cabo en dos años en 830 estudiantes. Resultados. En las escuelas de intervención, la disponibilidad de alimentos sanos aumentó y la disponibilidad de alimentos poco saludables disminuyó. La ingesta de alimentos en niños no mostraron las mismas tendencias. En las escuelas de intervención, los niños no participaron más en actividad física moderada y vigorosa. La prevalencia de obesidad no se modificó. Conclusión. La intervención mejoró el entorno alimentario escolar y las conductas saludables de alimentación y actividad física.

Physical activity during the school day in public primary schools in Mexico City / La actividad física durante la jornada escolar en escuelas primarias públicas en la Ciudad de México

OBJECTIVE: To quantify the physical activity (PA) of students and describe the school environment surrounding PA. MATERIAL AND METHODS: Between November 2005 and March 2006, in Mexico City, we conducted quantitative and qualitative observations to describe the PA and the school context. RESULTS: Recess and physical education class (PE) were the only opportunities to participate in PA. PE occurred one time per week with a duration of 39.8±10.6 minutes which is less than national and international recommendations. Students participated in moderate-to-vigorous PA 29.2±17.8 percent of PE. The dynamics of PE did not promote the inclusion of all students or PA. During recess there was overcrowding of the school patio and no equipment for PA or organization of PA. DISCUSSION: The PA of students in public schools in Mexico City can be improved by increasing the quantity and quality of PE and increasing opportunities for activity during recess.

OBJETIVO: Cuantificar la actividad física (AF) en niños escolares y describir el entorno escolar relacionado con la AF. MATERIAL Y MÉTODOS: Entre noviembre de 2005 y marzo de 2006 en la Ciudad de México, se realizó observación directa cuantitativa y cualitativa para describir el nivel de AF y el contexto escolar durante recreo y clases de educación física (CEF). RESULTADOS: El recreo y las CEF fueron los únicos espacios en los que se realizó AF. Las CEF se impartieron una vez a la semana y duraron 39.8±10.6 minutos, lo que está por debajo de las recomendaciones internacionales. Se participó en actividades moderadas-vigorosas 29.2±17.8 por ciento de las CEF. La dinámica de las CEF no favoreció la AF. Durante el recreo se observó saturación del patio y no se realizaron actividades organizadas ni se utilizaron materiales para promover la AF. DISCUSIÓN: Se recomienda incrementar la calidad y la cantidad de las CEF y el tiempo dedicado a jugar durante el recreo.
