Análisis de datos de estudios epidemiológicos con datos faltantes: métodos y aplicación en el estudio Universidad y Salud Mental (Estudio UniverSal)

Abstract

La presencia de los datos faltantes es un problema metodológico común de la investigación en salud. En este trabajo se han introducido los métodos imputación múltiple (MI) y ponderación por la probabilidad inversa (IPW) para tratar los datos faltantes y se han aplicado en el estudio UniverSal, un estudio multicéntrico y longitudinal que recoge información autorreportada de estudiantes universitarios sobre ideación y conducta suicida y los posibles factores de riesgo y protección. Se han estimado prevalencias de diferentes variables estudiadas y se ha aplicado un modelo de regresión Poisson de los posibles factores de riesgo y protección asociados con tener pensamiento o conducta suicida con el objetivo de comparar los resultados obtenidos al aplicar MI e IPW.
