Development and validation of a French version of the morningness-eveningness questionnaire
Chronobiol Int. 2024 Jan;41(1):81-92. doi: 10.1080/07420528.2023.2297960. Epub 2024 Jan 15.ABSTRACTThe aim of this study was to validate a French version (FMEQ) of the morningness-eveningness questionnaire (MEQ). Study 1 consisted of a translation by experts and an evaluation. The FMEQ and MEQ were proposed to 19 bilingual participants (age = 38.7 ± 13.7 years). Strong correlations between MEQ and FMEQ were obtained for most items. Study 2 tested the factorial structure and reliability of the FMEQ on a sample of 187 participants (20.46 ± 1.31 years). The confirmatory factor analysis indicated that the model had a good fi...

Tracing diurnal differences in brain anatomy with voxel-based morphometry - associations with sleep characteristics
Chronobiol Int. 2024 Jan 8:1-12. doi: 10.1080/07420528.2024.2301944. Online ahead of print.ABSTRACTMultiple aspects of brain functioning, including arousal, motivation, and cognitive performance, are governed by circadian rhythmicity. Although the recent rise in the use of magnetic resonance imaging (MRI) has enabled investigations into the macroscopic correlates of the diurnal brain processes, neuroanatomical studies are scarce. The current work investigated how time-of-day (TOD) impacts white (WM) and grey matter (GM) volumes using voxel-based morphometry (VBM) in a large dataset (N = 72) divided into two equal, comparab...

Lifestyle factors, dietary patterns, and social determinants of social and eating jetlag: A cross-sectional survey
Chronobiol Int. 2023 Dec 28:1-11. doi: 10.1080/07420528.2023.2298700. Online ahead of print.ABSTRACTSocial jetlag (SJL) and, more recently, eating jetlag have been linked with an increased risk of non-communicable diseases. Here we aim to investigate lifestyle factors (diet, eating behavior, smoking, perceived stress, time spent sedentary/day) and social determinants (education level, employment status, and place of residence) associated with SJL corrected for sleep duration (SJLsc) and eating jetlag. Self-declared data on age, gender, lifestyle, and eating behavior were collected online from March 2021 to February 2022 of...

Observational study to understand the effect of timing and regularity on sleep metrics and cardiorespiratory parameters using data from a smart bed
This study highlights how sleep regularity and chronotype influence sleep quality and cardiorespiratory metrics. Irrespective of chronotype, sleep regularity demonstrated a substantial effect. Further research is necessary to confirm these findings.PMID:38153128 | DOI:10.1080/07420528.2023.2298267 (Source: Chronobiology International)
