Aplicación móvil para el seguimiento del crecimiento y cuidado nutricional del bebé en hogares colombianos

Introducción: El predominio y asequibilidad actual de los teléfonos móviles inteligentes han permitido una amplia difusión de variedad de aplicaciones a nivel mundial para el monitoreo del crecimiento y del estado nutricional de los lactantes. No obstante, la mayoría de estos recursos no son lo suficientemente completos para proveer una interfaz amigable de seguimiento del crecimiento, combinada con una adecuada educación parental en materia de nutrición y alimentación complementaria. Objetivos: Este trabajo pretende presentar el desarrollo y evaluación de la aplicación propuesta "Baby Home", con el fin de estudiar su potencial como herramienta digital de apoyo a padres y cuidadores en el cuidado nutricional de sus niños desde el hogar. Materiales y métodos: Baby Home integra una interfaz de seguimiento interactivo del crecimiento del bebé con una serie de contenidos educativos alimentarios, posibilitando al usuario consultar las prácticas recomendadas según el estado nutricional estimado de su bebé. Un conjunto de 7 jueces expertos fue reunido para evaluar la validez de estos contenidos consignados en la aplicación. Posteriormente, se llevó a cabo un estudio de prueba piloto con 8 madres participantes, las cuales aportaron en las fortalezas y debilidades de las funcionalidades propuestas. Resultados: la aplicación desarrollada muestra una aprobación positiva por los especialistas consultados y una aceptación satisfactoria entre las madres participantes gracias a su diseño amigable y funcionalidades de fácil uso. Los recursos visuales implementados prueban ser adecuados para la apropiación de los contenidos alimentarios y el empoderamiento del usuario en torno a los cuidados nutricionales que requieren sus niños. Conclusiones: Baby Home se ubica como un soporte práctico y accesible para el cuidado nutricional del lactante, otorgando seguridad y confianza al usuario en la alimentación de su niño y disponiendo la posibilidad de detectar oportunamente problemas de crecimiento.

Introduction: The current prevalence and affordability of smartphones have enabled a broad diffusion of a variety of mobile applications worldwide for monitoring infant's growth and nutritional status. However, most of these resources are not comprehensive enough to provide a user-friendly interface for growth tracking combined with proper parental education on nutrition and complementary feeding. Objectives: This work aims to present the development and evaluation of the proposed application "Baby Home", in order to study its potential as a digital tool for supporting parents and caregivers in the nutritional care of their children from home. Materials and methods: Baby Home integrates an interactive baby growth monitoring interface with a collection of educational content on infant feeding, allowing the user to check the recommended practices based on the estimated nutritional status of their baby. A panel of seven expert judges was assembled to evaluate the validity of these contents included in the application. Subsequently, a pilot study was carried out with eight participating mothers who contributed to the strengths and weaknesses of the proposed functionalities. Results: The developed application received positive feedback by the consulted specialists and a satisfactory acceptance within the participating mothers thanks to its friendly design and easy-to-use functionalities. The implemented visual resources proved to be well suited for the user's appropriation of feeding contents and their empowerment regarding the nutritional care required by their children. Conclusions: Baby Home is positioned as a practical and accessible support for the nutritional care of infants, providing safeness and confidence to the user in their child's feeding and the possibility of timely detection of growth problems.

Efficacy of vitamin D supplementation in reducing body mass index and lipid profile in healthy young adults in Colombia: a pilot randomised controlled clinical trial.

The objective of the present study was to evaluate the efficacy of oral administration of vitamin D supplementation in reducing BMI and lipid profile in adolescents and young adults from a cohort in Bucaramanga, Colombia. One hundred and one young adults were randomly assigned to one of two doses of vitamin D [1000 international units (IU) or 200 IU] administered daily for 15 weeks. The primary outcomes were serum 25(OH)D levels, BMI and lipid profile. The secondary outcomes were waist-hip ratio, skinfolds and fasting blood glucose. We found a mean ± sd plasma concentration of 25-hydroxyvitamin D [25(OH)D] was 25⋅0 ± 7⋅0 ng/ml at baseline, and after 15 weeks, it increased to 31⋅0 ± 10⋅0 ng/ml in the participants who received a daily dose of 1000 IU, (P < 0⋅0001). For the participants in the control group (200 IU), it went from 26⋅0 ± 8⋅0 ng/ml to 29⋅0 ± 8⋅0 ng/ml (P = 0⋅002). There were no differences between groups in body mass index. There was a statistically significant decrease in LDL-cholesterol between the intervention group v. the control group (mean difference -11⋅50 mg/dl (95 % CI -21⋅86 to -1⋅15; P = 0⋅030). The conclusions of the present study were two different doses of vitamin D supplementation (200 IU v. 1000 IU) produced changes in serum 25(OH)D levels over 15 weeks of administration in healthy young adults. No significant changes were found in the body mass index when the effect of the treatments was compared. A significant reduction in LDL-cholesterol was found when comparing the two intervention groups. Trial registration: NCT04377386.

Seroprevalence of SARS-CoV-2 Infection among Occupational Groups from the Bucaramanga Metropolitan Area, Colombia.

The negative effects of coronavirus disease 2019 (COVID-19) pandemic have impacted the world economy due to the absence from work because of SARS-CoV-2 infection in workers, among other reasons. However, some economic areas are essential to society and people must continue working outside the home to support economic reactivation; their serological profile could be different from that of the global population. Cross-sectional study: Workers from health, construction, public transportation, public force, bike delivery messengers, independent or informal commerce areas, and residents of Bucaramanga or its metropolitan area were invited to participate. All participants self-completed a virtual survey and a blood test was taken to assess IgG and IgM with the ARC COV2 test. Seroprevalence was estimated considering a complex survey design, correcting for a finite population effect and adjusting for test performance. A total of 7045 workers were enrolled; 59.9% were women and most were residents of Bucaramanga and working in health occupations. The global adjusted seroprevalence was 19.5% (CI: 95% 18.6-20.4), being higher for Girón (27.9%; 95% CI: 24.5-31.30). Workers with multiple contact with people during working hours or using public transportation to go to work had a higher frequency of seropositivity for SARS-CoV-2. The seroprevalence among workers living in these four municipalities from the Colombian northeast area is still low.
