Background and Objectives: Metabolic syndrome (MS) has many risk factors that are important to investigate in populations living at sea level and in high-altitude geographic regions. The aim was to identify the components of MS that cross-sectional studies use to assess in adult populations residing in high-altitude regions. Materials and Methods: A systematic review study was conducted. The Pubmed database was used. The search for original articles (cross-sectional) was performed from January 2013 to December 2020. The procedure was carried out by two researchers. The keywords used were metabolic syndrome, adults, and altitude regions. The search strategy considered the components of the PICOS tool. Results: Ten cross-sectional studies were identified in the Pubmed database from 2014 to 2020. Altitude levels varied between countries and regions, from 2060 to 4900 m above sea level. Three studies were conducted in both China and Peru, two studies in Ecuador, and one in Bolivia and India. The age ranges studied were from 18 to ~80 years of age, approximately. The components used to assess MS in most studies (between 9 to 10 studies) were body mass index (BMI), waist circumference (WC), blood pressure (BP), triglycerides (TG), high-density lipoproteins (HDL) and serum glucose (SG). Conclusions: This systematic review verified that the most commonly used domains in adult populations in various moderate- and high-altitude regions of the world are BMI, WC, BP, TG, HDL, and SG. These results suggest that in order to evaluate and/or investigate MS in subjects residing in high-altitude populations, at least four diagnostic domains should be considered in their protocols.
Introducción: El objetivo del presente trabajo fue: a) validar el cuestionario que mide actividad física mediante análisis confirmatorio; b) analizar la fiabilidad por medio de medidas de estabilidad; y c) desarrollar percentiles por rango de edad y sexo.Material y métodos: Se efectuó un estudio de tipo descriptivo de corte transversal en 1.937 jóvenes universitarios (1.064 hombres y 873 mujeres) de la ciudad de Puno, Perú. Se midió el peso y estatura y se calculó el índice de Masa Corporal (IMC) por sexo. Se aplicó un cuestionario de 11 preguntas que mide actividad física. Se validó por Análisis Factorial Confirmatorio (AFC) y se verificó la confiabilidad por test re-test. Se generó percentiles por rango de edad y sexo para los patrones de actividad física por el método LMS.Resultados: Para el AFC se observó saturaciones entre 0,41 a 0,96, valores propios superiores a 1,0, el porcentaje de explicación de la varianza fue de 63,9% (Varimax y Kaiser-Meier-Olkin, KMO= 0,872. Esfericidad de X2= 4999,5, p<0,0000). La fiabilidad por test re-test mostró un Error Técnico de Medida (ETM) de 2,48 a 3,68% y un coeficiente de correlación intra-clase (CCI) entre 0,65 para hombres y 0,654 para mujeres y para ambos sexos CCI= 0,92.Conclusión: El cuestionario de 11 preguntas que mide actividad física es válido y confiable para jóvenes universitarios de una región de elevada altitud del Perú. Además, los percentiles propuestos sirven para identificar y clasificar los niveles de actividad física según rango de edad y sexo.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
