RESUMEN
Biosocial factors play a crucial role in the physical-motor development (PMD) of children during the preschool age. The present study aims to identify physical-motor profiles throughout preschool age (3-6 years) and explore associations between profiles and selected biosocial factors such as age, sex, prematurity, weight, height, BMI, and participation in extracurricular physical activities. Data from 412 typically developing children (46.6% girls and 53.4% boys), aged 35-71 months (M = 51.21, SD = 10.47) was collected using the Psychomotor Activities Checklist and specifically the scale of Psycho-Motor Aspects. Cluster analysis made it possible to define four different childhood PMD profiles. High PMD; High PMD except left laterality; medium-low PMD; and low PMD. High PMD profile includes older children, with anthropometric measurements closer to the WHO recommendations, fewer preterm children, and greater participation in extracurricular physical activities. Low PMD profile includes younger children, with weight slightly above and height slightly below the WHO recommendations and low participation in extracurricular physical activities. This study allows us to identify specific trends that may be decisive for the motor development of children throughout preschool age, highlighting selected biological variables and participation in extracurricular physical activities.
RESUMEN
INTRODUCTION: Voice disorders and burnout syndrome are common among teachers. This study aimed to explore the relationship among vocal problems, burnout syndrome, and some personal work factors. METHODS: This cross-sectional descriptive study enrolled 90 nonuniversity teachers who completed the Multidimensional Vocal Scale for Teachers (EVM-D) to evaluate vocal problems and an adapted Spanish version of the Maslach Burnout Inventory-Educators Survey (MBI-ES) to detect burnout syndrome. RESULTS: Overall, 16% of teachers expressed symptoms compatible with burnout, and 60% of them were in the interval above the 75th percentile of the EVM-D, i.e., they had a high risk of vocal problems. An association between burnout and more vocal problems was established among teachers, particularly between the vocal symptoms and vocal abuse dimensions with the emotional exhaustion subscale of the MBI-ES. A history of anxiety/depression and fewer years of professional experience were associated with more vocal problems. The burnout group perceived more "loss of vocal power," "vocal fatigue," "vocal effort," and "hoarseness." Vocal abuse items received the highest scores of EVM-D. However, only "shouting" in the classroom was significantly different between the groups with and without burnout. CONCLUSION: Emotional exhaustion of burnout syndrome, history of anxiety/depression, and a shorter professional experience were associated with vocal problems, which could limit the performance of teachers. Reducing classroom noise, establishing strategies to avoid shouting, or strengthening personal accomplishments in teachers could be useful in breaking the cycle of vocal problems and emotional exhaustion, particularly at the beginning of their professional experience.
