ABSTRACT

AIMS: To investigate associations between outdoor and screen time and changes in sleep patterns in children from two nationwide birth-cohorts in the SAPRIS project. METHODS: During the first French COVID-19 pandemic lockdown, volunteer parents of children enrolled in the ELFE and EPIPAGE2 birth-cohorts completed online questions about their child's outdoor time, screen time, and changes in sleep duration and quality compared with the pre-lockdown situation. In 5700 children (aged 8-9 years, 52% boys) with available data, we assessed associations between outdoor time, screen time, and sleep changes using multinomial logistic regression models adjusted for confounders. RESULTS: Children spent on average 3 h08 outdoors and 4 h34 using screens/day (3 h27 for leisure, 1 h07 for class-work). Sleep duration increased in 36% of children and decreased in 13.4%; sleep difficulties appeared/increased in 22.5% and decreased/disappeared/remained stable in 18.3%. After adjustment, increased screen time, especially for leisure, was associated with increased and decreased sleep duration (OR(95%CI) = 1.03(1.00-1.06) and OR = 1.06(1.02-1.10), respectively). No association was observed between outdoor time and sleep changes after adjustment. CONCLUSIONS: Our study adds evidence for the association between high leisure-time screen time and shorter sleep time. It supports current screen guidelines for children, especially during leisure time and for those whose sleep duration is short.

ABSTRACT

The COVID-19 pandemic and associated lockdowns triggered worldwide changes in the daily routines of human experience. The Blursday database provides repeated measures of subjective time and related processes from participants in nine countries tested on 14 questionnaires and 15 behavioural tasks during the COVID-19 pandemic. A total of 2,840 participants completed at least one task, and 439 participants completed all tasks in the first session. The database and all data collection tools are accessible to researchers for studying the effects of social isolation on temporal information processing, time perspective, decision-making, sleep, metacognition, attention, memory, self-perception and mindfulness. Blursday includes quantitative statistics such as sleep patterns, personality traits, psychological well-being and lockdown indices. The database provides quantitative insights on the effects of lockdown (stringency and mobility) and subjective confinement on time perception (duration, passage of time and temporal distances). Perceived isolation affects time perception, and we report an inter-individual central tendency effect in retrospective duration estimation.

ABSTRACT

Objectif Étudier l’impact du 2° confinement sur le sommeil des Français. Méthodes Enquête par internet réalisée du 8 au 15 janvier 2021 par OpinionWay, sur 1010 personnes (18–65 ans) représentatives de la population française, selon la méthode des quotas (âge, sexe, csp, région). Questionnaire défini par le conseil scientifique de l’INSV. Résultats Alors que les horaires de sommeil ont été peu modifiés par rapport à une période normale, la fréquence des troubles du sommeil a augmenté de 41 % à 45 %, associé à une augmentation du nombre de sujets s’éveillant la nuit (64 à 70 %). Ce 2° confinement est associé à un sentiment d’anxiété (33 %), et de dépression (34 %) avec une fatigue moyenne à 5,1/10 (Échelle Visuelle Analogique), fatigue apparue chez 12 %, et aggravée chez 17 %, des sujets. Vingt-trois pour cent des sujets ont cherché à améliorer leur sommeil, avec succès dans plus de 70 % des cas. Cent quarante-quatre sujets de notre échantillon ont été testés COVID+. Par rapport à l’ensemble de l’échantillon ces derniers sont plus nombreux à être anxieux (66 % vs 34 %), déprimés (59 % vs 33 %), à avoir des troubles du sommeil avant et pendant le confinement (60 et 64 % vs 41 et 45 %). Conclusion Le sommeil semble s’être moins dégradé que lors du 1° confinement, mais l’anxiété la dépression et la fatigue sont très anormalement présentes. Les sujets COVID+ sont plus fragiles sur le plan de leur sommeil et de leur état psychologique.
