ABSTRACT
Objetivo: Determinar la eficacia de dos herramientas electrónicas en el levantamiento de índices aédicos en la ciudad Villavicencio. Métodos: Se realizó un estudio de tipo observacional, analítico en dos barrios de la ciudad Villavicencio: Quintas de San Fernando y Cedritos. El formato de levantamiento de índices aédicos de la secretaría de salud fue diseñado en dos medios electrónicos. La eficacia fue determinada mediante datos efectivos recogidos y tiempo de entrega. Se calcularon índices aédicos, Breteau, vivienda y pupas. Se realizó encuesta para determinar actitudes frente a arbovirosis. Se realizó estadística descriptiva, pruebas de chi cuadrado y t-Student (p< 0,05). Resultados: Se evaluaron 67 predios en dos barrios. El índice de datos efectivos fue mejor en donde el acceso a internet era permanente (100 por ciento vs. 23,9 por ciento); el tiempo de entrega también se afectó por esta conexión. Se encontraron diferencias significativas en el número de viviendas positivas para Aedes aegypti entre los dos barrios (p= 0,0052); y para el número de tanques bajos positivos (p= 0,0123). De los encuestados, el 16,4 por ciento (IC95 por ciento 8,9 por ciento-27,5 por ciento) sabía que la transmisión fue por picadura de Ae. aegypti. Para el 79,1 por ciento, cada familia fue responsable de eliminar criaderos. Conclusiones: El uso de herramientas electrónicas permite acelerar el flujo de la información y crear un sistema eficaz, de fácil acceso y seguridad que podría implementarse permanentemente en la vigilancia entomológica y de salud pública(AU)
Objective: Determine the effectiveness of two electronic tools for the evaluation of aedic indices in the city of Villavicencio. Methods: An observational analytic study was conducted in two districts in the city of Villavicencio: Quintas de San Fernando and Cedritos. The form designed by the Ministry of Health to evaluate aedic indices was digitalized into two electronic media. Efficacy was determined on the basis of effective data collected and delivery time. An estimation was made of aedic indices, Breteau, household and pupae. A survey was conducted to determine attitudes to arbovirus infections. Use was made of descriptive statistics, chi-squared tests and Student's t-test (p< 0.05). Results: Sixty-seven households were evaluated in two districts. The effective data index was better in areas where access to the Internet was permanent (100 percent vs. 23.9 percent). Delivery time was also affected by Internet connection. Significant differences were found between the two districts in the number of positive households for Aedes aegypti (p= 0.0052), as well as in the number of positive ground water tanks (p= 0.0123). Of the respondents, 16.4 percent (95 percent CI, 8.9 percent-27.5 percent) were aware that transmission had been by the bite of Ae. aegypti mosquitoes. For 79.1 percent each family was responsible for eliminating the breeding sites. Conclusions: Use of electronic tools speeds up the flow of information and creates an effective, easily-accessible and safe system which could be permanently implemented for entomological and public health surveillance(AU)

RESUMEN Introducción: Los estudiantes universitarios son particularmente vulnerables a una inadecuada nutrición, con la subsecuente afectación en su estado nutricional y de salud. Objetivo: Investigar la frecuencia de exceso de peso (EP) y algunos de sus factores asociados en estudiantes de la Universidad de Antioquia-Colombia. Métodos: Estudio transversal en 424 estudiantes, ambos sexos, con edades de 21,4±4,0 años. El EP se diagnosticó según índice de masa corporal (IMC) ≥ 25 kg/m2; el riesgo de adiposidad central (RAC) como perímetro de cintura (PC) ≥ 80 cm en mujeres y ≥ 90 cm en hombres. Se midieron variables sociodemográficas y asociadas con el estilo de vida (EV). Se empleó estadística descriptiva, prueba Chi2 y α = 0,05. Resultados: El 17,1% de los estudiantes presentó EP, mayor en hombres que en mujeres (22,6% vs 14,0%); un 8,1% mostró RAC, mayor en mujeres (9,1% vs 6,5%). El IMC se asoció con el sexo (p= 0,001). El RAC no mostró asociación con las características sociodemográficas ni de EV. Conclusión: Un porcentaje considerable de los universitarios presentó exceso de peso establecidos a partir de IMC, lo cual fue asociado al sexo del estudiante. No obstante, es importante promover espacios universitarios que propendan por estilos de vida saludables.
ABSTRACT Introduction: University students are particularly vulnerable to inadequate food intake, which has consequences for their nutritional and health status. Objective: To study the prevalence of overweight (OW) and its associated factors among a group of students at University of Antioquia, Colombia. Materials and Methods: Cross-sectional study involving 424 male and female students 21.4±4.0 years of age. OW was diagnosed by body mass index (BMI) ≥ 25 kg/m2; risk of central adiposity was measured by waist circumference (WC) ≥ 90 cm and ≥ 80 cm in men and women, respectively. Socio-demographic and lifestyle variables were measured. Chi2 test (a = 0.05) was used as a descriptive statistic. Results: 17.1% of students had OW, which was higher in men (men: 22.6% vs women 14.0%, p< 0.05); 8.1% had risk of central adiposity higher, which was higher in women (men: 6.5% vs women: 9.1%, p> 0.05). BMI was associated with sex (p= 0.001). Risk of central adiposity was not related with socio-demographic or lifestyle characteristics. Conclusion: A considerable percentage of university students were overweight based on BMI, which related to sex of the student. However, it is important to promote university spaces that are conducive to healthy lifestyles.

Abstract Objective: to observe the relationship between socioeconomic status, height and nutritional problems related to obesity, overweight and risk of metabolic complications in men and women of Medellin (Colombia). Methods: cross-sectional study with a sample of 5,556 adults between 18 and 69 years of age. We assessed weight, height and waist circumference. Socioeconomic variables were evaluated by family income, socioeconomic stratum and academic level achieved. Results: we found that in men and women the height reached in adulthood is associated with socioeconomic conditions as measured by the socioeconomic strata and family income. In women, height, age, and socioeconomic strata are associated with obesity, overweight and risk of obesity, and risk of metabolic complications. Conclusion: These results are not only from individual unhealthy habits, such as eating patterns based on high density foods combined with low energy expenditure, but also from the cumulative effect of food deprivation throughout life. Therefore, policies intended to prevent them should take a preventive approach that begins before birth and continues during childhood and adulthood.
Resumen Objetivo: Observar las relaciones entre estatus socioeconómico, estatura y problemas nutricionales de sobrepeso, obesidad, riesgo de complicaciones metabólicas en hombres y mujeres de Medellín. Métodos: estudio transversal, descriptivo con una muestra de 5,556 adultos con edades entre 18 y 69 años. Se evaluaron peso, estatura y perímetro de cintura. Como variables socioeconómicas se evaluaron los ingresos familiares, el estrato socioeconómico y el nivel educativo. Resultados: Se encontró que en hombres y mujeres la estatura alcanzada está asociada con las condiciones socioeconómicas medidas por estrato e ingresos familiares. En las mujeres la estatura alcanzada, la edad y el estrato están asociados con la obesidad, el sobrepeso y los riesgos de complicaciones metabólicas. Conclusión: la obesidad, el sobrepeso y el riesgo de complicaciones metabólicas en la adultez son el resultado no solo de hábitos individuales no saludables como patrón alimentario basado en alimentos altamente energéticos, sumado a bajo gasto calórico, sino también a una acumulación de privaciones alimentarias a lo largo de la vida y deben ser intervenidas antes del nacimiento y durante la infancia y la adultez.
ABSTRACT
Lutzomyia antunesi has been commonly reported in outbreaks of cutaneous leishmaniasis (CL) in the Orinoquia region of Colombia. The bionomics of this species were studied in the municipality of Villavicencio (Meta, Colombia). Sandflies were captured over the course of one week per month for one year in intradomiciliary, peridomiciliary and extradomiciliary housing areas. The captures were performed from 06:00 pm-06:00 am using CDC light traps and the females were processed for polymerase chain reaction (PCR) to detect Leishmania spp. A total of 22,097 specimens and 19 species were captured of which Lu. antunesi (89%) and Lutzomyia walkeri (5%) were the most abundant. Other species recognised as anthropophilic (Lutzomyia panamensis, Lutzomyia gomezi, Lutzomyia flaviscutellata and Lutzomyia fairtigi) were present in very low abundance (< 2%). Natural infection with Leishmania spp was detected using PCR in Lu. antunesi, Lu. panamensis and Lu. flavicutellata, showing infection rates of 1%, 4.8% and 7.5%, respectively. The present paper provides information on various ecological aspects of Lu. antunesi. An analysis of seasonality shows that this species increases in abundance in the hottest months (December, January and February), directly correlating with the maximum temperature and inversely correlating with precipitation. The natural infection rate is associated with the peaks of highest abundance.
