ABSTRACT
Introduction: The prevalence of obesity in the Mexican school-age (5-11 years old) population increased from 8.9 to 18.1% between 1999 and 2022. Although overweight and obesity (OW + Ob) is a complex and multifactorial phenomenon, alongside its increasing trend, changes in eating patterns as a result of obesogenic environments that promote higher energy intake have been documented. The objective of the present study was to detect possible associations between schools and their proximity to and density of convenience stores in Monterrey, Mexico from 2015 to 2018. Materials and methods: Anthropometric data were obtained from a subset of measurements of the National Registry of Weight and Height (RNPT) performed in the Monterrey Mexico metropolitan area in 2015 and 2018, and obesity prevalence was computed and classified into quintiles at the school level. Convenience store data were obtained from the National Directory of Economic Units (DNUE). The analyses consisted of densities within 400-800 m buffers, distance to the nearest stores, and cartographic visualization of the store's kernel density versus OW + Ob hotspots for both periods. Results: A total of 175,804 children in 2015 and 175,964 in 2018 belonging to 1,552 elementary schools were included in the study; during this period, OW + Ob prevalence increased from 38.7 to 39.3%, and a directly proportional relationship was found between the quintiles with the higher OW + Ob prevalence and the number of stores for both radii. Hotspots of OW + Ob ranged from 63 to 91 between 2015 and 2018, and it was visually confirmed that such spots were associated with areas with a higher density of convenience stores regardless of socioeconomic conditions. Conclusion: Although some relationships between the store's proximity/density and OW + Ob could be identified, more research is needed to gather evidence about this. However, due to the trends and the magnitude of the problem, guidelines aimed at limiting or reducing the availability of junk food and sweetened beverages on the school's periphery must be implemented to control the obesogenic environment.
ABSTRACT
Introducción: La varicela es una enfermedad viral aguda altamente contagiosa, de comienzo repentino, con fiebre moderada, síntomas generales, erupción cutánea de tipo maculopapular y vesicular; afecta principalmente a menores de 10 años. Objetivos: Describir el comportamiento de la varicela entre 2003/2007 en Pradera (Valle del Cauca). Métodos: Se realizó un estudio observacional descriptivo producto de los registros del Sistema de Vigilancia en Salud Pública de Pradera, secundarios a la recolección de casos de varicela notificados por los prestadores de servicios de salud municipales semanalmente. Resultados: Se observó un incremento de 10 veces las tasas de varicela en 2006 respecto a 2003; afectó principalmente a menores de 1 a 4 años (14 veces), seguido de adultos jóvenes entre 15 a 44 años (13 veces) y de 45 a 59 años (9 veces); se enfermaron también personas de edades extremas (menores de un año - mayores de 60). Conclusiones: Por su alto poder epidémico la varicela requiere para su control y prevención la movilización de diferentes sectores poblacionales: salud, social y educación; es un evento que al no controlarse adecuadamente afecta a grupos poblacionales inhabituales (mayores de 15 años y menores de 1 año). Las estrategias de control y prevención implementadas entre las secretarías de Salud Municipal de Pradera y Departamental del Valle al parecer contribuyeron a mitigar la diseminación de este evento durante 2007.
Introduction: Chickenpox is a acute viral illness highly contagious of sudden onset with mild fever, general symptoms, maculopapular rash and vesicular type, affecting mainly children under 10 years. Objectives: To describe the behavior of chickenpox between 2003 /2007 in Padrera. (Valle del Cauca). Methods: A descriptive study was made of the records product Surveillance System in Public Health in Pradera secondary to the collection of cases of chickenpox reported by providers of municipal health services weekly. Results: We observed an increase of 10 times the rates for chickenpox in 2006 compared to 2003; this mainly affected children from 1 to 4 years (14 times), followed by young adults between 15 and 44 years (13 times) and 45 to 59 years (9 times); there were also people ill in extreme age (under one year - over 60). Conclusions: The Chickenpox by a high epidemic power required for control and prevention mobilization of different sectors of the population: health, social and education; it is an event that when not controlling properly affects unusual population groups (older than 15 years and less than 1 year). The prevention and control strategies implemented between the Secretaries Local Health in Pradera and Department of Valle helped to mitigate further spread of this event in 2007.
