“…Due to pandemic restrictions, most of the studies collected data through online surveys. Sixty-one studies used self-reported instruments ( 30 – 76 , 79 – 92 ) and 2 device-based (DB) ones ( 77 , 78 ). Of the former, 20 used validated instruments ( 32 , 33 , 42 , 43 , 47 , 51 , 54 , 61 , 63 , 65 , 66 , 68 , 69 , 71 – 73 , 84 , 85 , 88 , 90 ) (17 PSQI), and 41 used researcher-developed ones ( 31 , 34 – 41 , 44 – 46 , 48 – 50 , 52 , 53 , 55 – 60 , 62 , 64 , 67 , 70 , 74 – 76 , 79 – 83 , 86 , 87 , 89 , 91 , 92 ).…”

Changes in sleep quality and sleep disturbances in the general population from before to during the COVID-19 lockdown: A systematic review and meta-analysis

et al. 2023

IntroductionThis systematic review and meta-analysis aims to explore changes in sleep quality and sleep disturbances in the general population from before to during the COVID-19 lockdown.MethodsThe protocol was registered in PROSPERO (CRD42021256378) and the PRISMA guidelines were followed. The major databases and gray literature were systematically searched from inception to 28/05/2021 to identify observational studies evaluating sleep changes in the general population during the lockdown with respect to the pre-lockdown period. A random effects meta-analysis was undertaken for studies reporting (a) the means of the Pittsburgh Sleep Quality Index (PSQI) global scores or the means of the sleep onset latency (SOL) times (minutes - min) before and during the lockdown, (b) the percentages of poor sleep quality before and during the lockdown, or (c) the percentages of changes in sleep quality. Subgroup analysis by risk of bias and measurement tool utilized was carried out. A narrative synthesis on sleep efficiency, sleep disturbances, insomnia and sleep medication consumption was also performed.ResultsSixty-three studies were included. A decline in sleep quality, reflected in a pooled increase in the PSQI global scores (standardized mean difference (SMD) = 0.26; 95% CI 0.17–0.34) and in SOL (SMD = 0.38 min; 95% CI 0.30–0.45) were found. The percentage of individuals with poor sleep quality increased during the lockdown (pooled relative risk 1.4; 95% CI 1.24–1.61). Moreover, 57.3% (95% CI 50.01–61.55) of the individuals reported a change in sleep quality; in 37.3% (95% CI 34.27–40.39) of these, it was a worsening. The studies included in the systematic review reported a decrease in sleep efficiency and an increase in sleep disturbances, insomnia, and in sleep medication consumption.DiscussionTimely interventions are warranted in view of the decline in sleep quality and the increase in sleep disturbances uncovered and their potentially negative impact on health. Further research and in particular longitudinal studies using validated instruments examining the long-term impact of the lockdown on sleep variables is needed.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021256378, identifier CRD42021256378.

“…A possible explanatory reason for this discrepancy could be the circumstances of the COVID-19 lockdown. Indeed, a recent study on the impact of COVID-19 pandemic on different chronotype profiles reported an unexpected increase in the amount of food intake consumed near bedtime for those with a morning chronotype [62]. They found that those with a morningness profile were less likely to maintain regular schedules during the pandemic period.…”

The COVID-19 lockdown has had a significant impact on people’s lives worldwide. This study aimed to investigate the effect of personality on chrononutrition during the COVID-19 lockdown. Using a cross-sectional design, a convenient sample of 543 adults in Qatar completed an online questionnaire using validated tools to assess personality and chrononutrition behaviors during the first COVID-19 lockdown. Participants scoring high in openness were more likely to eat at night (mean difference (MD) = 0.41, 95% confidence interval (CI): 0.10, 0.72) compared to those scoring high in agreeableness, while those scoring high in extraversion and openness had a shorter eating window (MD = −76.6, 95%CI: −146.3, −6.93 and MD = −29.8, 95%CI: −56.5, −3.01, respectively). Participants high in extraversion had longer evening latency (MD = 66.3, 95%CI: 25.4, 107.3) and evening eating (MD = −62.0, 95%CI: −114.0, −9.0) compared those high in agreeableness. Participants high in conscientiousness showed evidence of first eating event misalignment during the weekend (MD = 22.0, 95%CI: 0.15, 43.9) and last eating event misalignment during weekdays (MD = −27.8, 95%CI: −47.3, −8.41) compared to those high in agreeableness. Lastly, participants high in openness showed evidence of eating window misalignment during the weekend (MD = 30.6, 95%CI: 5.01, 56.2). This study suggests that personality traits can inform personalized nutritional approaches when aiming for healthy habits during unexpected periods, such as the COVID-19 pandemic.

“…2 University life is a period in which organizational and socio-cultural behaviors can change, which can have an effect that alters the chronotype by influencing different habits such as diet and physical activity. 3 The individual differences in both teenagers and adolescents according to the sleep-wake model called chronotype are among the factors that play a major role in the functioning and behavior of the organism. 4 These differences in chronotypes can be associated with socioeconomic, educational, and environmental disadvantages, as well as contributing to the increase in consumption of unhealthy foods.…”
