    Procrastination in University Students: A Proposal of a Theoretical Model
    (MDPI, 2023-02) Araya-Castillo, Luis; Burgos, Mildred; González, Patricia; Rivera, Yuracid; Barrientos, Nicolás; Yáñez Jara, Víctor; Ganga-Contreras, Francisco; Sáez, Walter
    Procrastination is a phenomenon that affects university students and consists of not finishing a task or finishing it late, which has a direct impact on their academic performance. This is relevant because, in a context of high competition, higher education institutions and their decision-makers need to be aware of the factors that influence university students’ procrastination in order to implement actions that favor student attraction and retention. Based on the above, this research aims to propose a theoretical model of procrastination in university students, based on the literature review and content validation assessment through a semi-structured questionnaire. The proposed model is made up of nine dimensions: Psychological, Physiological, Social, Academic, Leisure, Time Management, Resources, Labor, and Environmental. Dimensions were obtained based on adequate levels of content validity provided by the literature and the questionnaire. In the future, the research proposes to study the way in which these dimensions are present in procrastination and design a scale that allows for their measurement. © 2023 by the authors.

    Temporal trends and factors associated with preterm birth in Chile, 1992-2018
    (Universidad Nacional de Lanos, 2023) Toro-Huerta, Carol; Vidal, Carolina; Araya-Castillo, Luis
    An analytical study based on Chilean birth records obtained from the Department of Statistics and Health Information (DEIS) was conducted. This study aimed to evaluate temporal trends in preterm births by maternal age in Chile from 1990 to 2018. Results show that the preterm birth rate in 1992 was 5.0% and increased to 7.2% in 2018. The average annual percent change (AAPC) was 1.44. Age groups at the extremes (19 and under and 35 and over) presented the highest rates of preterm birth, both at the beginning and at the end of the study period. The latter group showed a smaller decrease at the beginning (1992 to 1995), with an annual percentage change (APC) of -3.00. The probability of preterm birth in both groups was higher compared to the 20-34 year old group. Although Chile boasts some of the best maternal and child health indicators in the region, repercussions associated with the current postponement of maternity – including preterm birth – must be monitored. © This work is under Creative Commons license Attribution 4.0 International (CC BY 4.0).
