Problematic Use of Smartphones and Social Media on Sleep Quality of High School Students in Mexico City.

BACKGROUND: Smartphones, internet access, and social media represent a new form of problematic behavior and can affect how teens sleep. METHODS: A cross-sectional design was employed to examine the prevalence and association of problematic internet use and problematic smartphone use with sleep quality in a non-probability sample of 190 high school students in Mexico. The internet-related experiences questionnaire (IREQ), the mobile-related experiences questionnaire (MREQ), and the Pittsburgh Sleep Quality Index (PSQI) were used. RESULTS: The study revealed that 66% of participants exhibited some form of problematic internet use, primarily in the form of social media use; 68% had some form of problematic smartphone use, and 84% reported poor sleep quality. The PSQI score was most accurately predicted by problematic smartphone use (MREQ), followed by enrollment in the morning school shift, participation in sports, the father's education level, and knowledge that "smartphone use disturbs sleep", which together explained 23% of the variation in sleep quality. CONCLUSIONS: Excessive smartphone use may negatively affect sleep quality in adolescents. We recommended that interventions be implemented to educate adolescents about appropriate and healthy use of technology, in parallel with the promotion of preventive sleep habits.

The Role of Functional Deficits, Depression, and Cognitive Symptoms in the Perceived Loneliness of Older Adults in Mexico City.

The world is aging and experiencing loneliness. Functional impairment in instrumental activities of daily living (IADL) in older people (OP) with mild neurocognitive disorder (MNCD) predicts loneliness. After the pandemic, there was an increase in perceived loneliness. We explored the association between loneliness, depression, deficits in IADL, and cognitive symptoms among OP. From February to December 2023, using a cross-sectional design, we interviewed probable cases with mild cognitive impairment and caregivers in two public facilities. We administered the UCLA Loneliness Scale v3, Lawton IADL Scale, Mini-Mental State Examination (MMSE), and Yesavage's Geriatric Depression Scale. Samples were matched: 85 per group, 82.4% were women, married (52.95%), and mean age of 69.17 (±6.93) years. In our study, 30% displayed moderate to high levels of perceived loneliness. Multivariate analysis showed loneliness was associated with depression, low levels of IADL, and older age, but not with cognitive symptoms, which explained 22% of the total variance (F 165) = 16.99, (p < 0.001). Targeting symptoms and behaviors that could be modified (i.e., depression and functionality) can improve feelings of perceived loneliness and have an impact on morbidity and mortality with which it is associated.

Sleep and Perceived Stress: An Exploratory Mediation Analysis of the Role of Self-Control and Resilience among University Students.

BACKGROUND: High levels of stress are frequent in university education, and a lack of sleep has been reported to make students more vulnerable to stress. The mechanisms through which sleep harms students have not been sufficiently clarified; therefore, this study aimed to explore the mediating role of self-control and resilience in the relationship between sleep quality and duration and perceived stress. METHODS: Of 32 first-year college students, 21 (78%) were women, with a mean age of 18.47 (±0.84). They responded to a self-administered survey that included questions on stress, resilience, and sleep quality and recorded their daily sleep duration using a wristband for six days. RESULTS: Perceived stress was significantly correlated with resilience (r = -0.63), self-control (r = -0.46), sleep duration (r = -0.35), and lower sleep quality (r = 0.57). Path analysis revealed that self-control and resilience were partially mediated by sleep quality (R2 = 0.62; p < 0.01) and completely mediated by sleep duration (R2 = 0.46; p < 0.01). In both models, self-control had a direct effect on resilience and had a good-fit index. CONCLUSION: Being resilient seems to play a mediating role in the relationship between sleep and perceived stress; this ability can be favored by self-control, which is directly influenced by sleep.

The contribution of self-concept to sleep quality in adolescents: A cross-sectional study.

Self-concept has been associated with health-related behaviors and emotional self-regulation, which can improve sleep. However, its involvement in sleep quality in a healthy adolescent population has been little studied. This study evaluated the association between self-concept and sleep quality in adolescents adjusting for sleep/wake habits. The cross-sectional study included 1,751 adolescents, 54% females, with an age of M = 16.76 ± 1.04 years. The information was collected through an electronic survey that contained the Patient Health Questionnaire, Sleep Habits Questionnaire, Pittsburgh Sleep Quality Index, and Self-Concept Scale. A significant association between self-concept, adjustment for adolescents´ characteristics and sleep/wake habits was observed (R2 = .17, F = 26.61, p < .001). That is, in addition to the adolescent habits, self-concept also contributed to the explanation of sleep/wake habits. These results reinforce the idea that the self-concept can be an essential factor that contributes to better sleep quality, despite the habits of adolescents.

Doctoring and mothering during the SARS-COV2 pandemic: Characteristics of physicians-mothers during COVID-19 and their impact on mental health / Medicina y maternidad durante la pandemia por SARS-COV2: Características de médicas madres de familia durante la Covid-19 y su impacto en la salud mental

Abstract Introduction During COVID-19, health workers faced increased stress accentuated by gender roles, such as motherhood. Objective This study analyzed the characteristics of a group of physicians-mothers, its impact on mental health, and their experiences during this pandemic. Method Mixed methods study using an online survey to investigate sociodemographic, family, emotional, and professional aspects, in addition to the personal experience of 537 doctors-mothers during the first stage of COVID-19. Results Due to the pandemic, most of the participants changed their daily activities. The hours dedicated to professional work (HM = 5.08, p< .0001), childcare (HM = 3.74, p< .0001), and food planning and preparation (HM = -6.96, p< .0001) were increased, while the hours dedicated to physical exercise (MH = 8.67, p< .0001) and personal care (MH = 9.54, p< .0001) decreased. It has been pointed out that this pandemic has generated a lack of well-defined spaces, resulting in multitasking. Fear and guilt were two common words in the speeches of the participants. Fear of getting sick and dying, or fear of infecting their families. Guilt at feeling that they did not play a good role either as doctors or as mothers. Most common psychological symptoms were insomnia, sadness or discouragement, and constant worry or tension. Discussion and conclusion The pandemic evidenced and exacerbated both the disparities faced by these female doctors in the medical field, as well as the inequity in housework and home-care. The loss of boundaries between the public and the private showed the mothers-doctor struggling to reconcile their personal and professional life with substantial repercussions for their mental health.

Resumen Introducción Durante el COVID-19, los trabajadores de la salud enfrentaron mayor estrés, acentuado por los roles de género, como la maternidad. Objetivo Analizar las características de un grupo de madres médicas, su impacto en la salud mental, y sus experiencias durante esta pandemia. Método Estudio de métodos mixtos mediante una encuesta en línea que indagó aspectos familiares, emocionales, profesionales y la experiencia personal de 537 madres médicas durante la primera etapa del COVID-19. Resultados Por la pandemia, las participantes cambiaron sus actividades diarias. Asimismo, incrementaron el número de horas dedicadas al trabajo profesional (HM = 5.08, p< .0001), el cuidado de niños (HM = 3.74, p< .0001) y la planificación y preparación de alimentos (HM = -6.96, p< .0001). Disminuyeron las horas dedicadas al ejercicio físico (MH = 8.67, p< .0001) y al cuidado personal (MH = 9.54, p< .0001). Señalaron que esta pandemia generó una falta de espacios definidos, lo que favoreció el multitasking. Miedo y culpa fueron dos palabras habituales en los discursos de las participantes. También miedo a enfermarse y morir, o miedo a contagiar a sus familias. Culpabilidad por sentir que no desempeñaron un buen papel ni como médicas ni como madres. Los síntomas psicológicos más comunes fueron insomnio, tristeza y tensión constante. Discusión y conclusión La pandemia evidenció y exacerbó las disparidades que enfrentan estas doctoras en el campo de la medicina y la inequidad en las tareas del hogar. La pérdida de los límites entre lo público y lo privado mostró a las médicas madres conciliando su vida personal y profesional, con repercusiones sustanciales para su salud mental.

Indicators of vulnerability associated with less healthy circadian rhythms in undergraduate medical interns.

To evaluate the association between circadian health parameters and psychological and biological vulnerability, a cross-sectional study was conducted with 15 undergraduate medical interns using the Brief Resilience Scale, the Mini International Neuropsychiatric Interview, and an ambulatory circadian monitoring device. Circadian Health construct was confirmed by factor analysis. Vulnerability factors (history of depression and low resilience) were associated to lower circadian health of motor activity and temperature rhythms. The findings suggest that not only being depressed but also having had depressive episodes in the past, as well as having low resilience, are associated with chronodisruption, and may increase the risk for developing new episodes of depression.
