Sleep as a Priority: 24-Hour Movement Guidelines and Mental Health of Chinese College Students during the COVID-19 Pandemic.

ABSTRACT: Research on the combined role of 24-hour movement behaviors (sleep, sedentary behavior [SB], and physical activity) in adult mental health, though important, is in its infancy. In the context of Canadian 24-hour movement guidelines integrating quantitative recommendations for sleep, SB, and moderate-to-vigorous physical activity (MVPA), this study aimed to examine the associations between meeting guidelines and mental health among college students. The study used a cross-sectional sample of 1846 Chinese college students surveyed online in August 2020. Through network analysis and multivariate analysis of covariance, the individual and combined associations between meeting 24-hour movement guidelines and the levels of depression and anxiety after adjusting sociodemographic factors were analyzed. Results indicated that meeting the sleep guideline had stronger associations with depression and anxiety than meeting the SB or MVPA guideline. Specifically, compared to meeting no guidelines, meeting the sleep guideline (alone or in combination with other guidelines) was associated with significantly lower levels of depression and anxiety; meeting both SB and MVPA guidelines was also associated with a significantly lower level of depression. Hence, meeting more guidelines, especially adhering to a healthy sleep routine, may play an important role in promoting the mental health of young adults.

Project description:BackgroundUnhealthy eating habits, such as low vegetable and fruit intake, are associated with many health problems. 24-h movement behaviors have been reported to be positively associated with numerous health-related outcomes. Despite the importance of these two modifiable lifestyle behaviors in building healthy habits in university students, there is a paucity of relevant research in this population. Therefore, this study aims to examine the correlation between compliance with 24-h movement guideline (24-h MG) and intake of fruits and vegetables (IFV) in Chinese university students.MethodsThis study investigated the relationship between the compliance with 24-h MG and IFV in 1,793 Chinese university students using a convenience sampling method online. Physical activity (PA) and sedentary behavior (SB) were assessed by the International Physical Activity Questionnaire-Short Form, while sleep was measured using the Pittsburgh Sleep Quality Index. The Chinese version of the Health Promoting Lifestyle Profile II was used to measure IFV. Generalized linear models were applied to examine the correlation between compliance with the 24-h MG and eating habits.ResultsThe proportion of participants who routinely consumed vegetables and fruits was 24.6% and 43.1%, respectively, while the proportion of meeting the three 24-h MG and a combination of any two guidelines was 27.8% and 40.1%, respectively. Meeting all three guidelines was associated with a greater IFV intake compared to not meeting either guideline. Meeting all three guidelines (OR = 2.42 [1.63, 3.58]) and the combination of moderate to vigorous PA (MVPA) and sleep (OR = 2.06 [1.37, 3.10]) were positively associated with the frequency of vegetable consumption (p < 0.05). As well, meeting all three guidelines (OR = 2.06 [1.37, 3.10]), the combination of MVPA and sleep (OR = 1.72 [1.04, 2.84]), and sleep only (OR = 1.88 [1.21, 2.92]) were positively associated with fruits consumption (p < 0.05).ConclusionAlmost a third of the university students met the three 24-h MG, and compliance with all three guidelines was associated with a higher frequency of IFV. Furthermore, meeting the sleep guideline alone or in conjunction with the PA, and meeting the entire 24-h MG was associated with greater consumption of fruits.

Project description:ObjectiveChildhood is a critical period for brain development. However, it remains unknown whether the behaviors in a typical 24-h day are related to children's executive function (EF). This study aimed to investigate the relationship between the 24-h movement guidelines and children's EF.MethodChildren aged 7-12 years (n = 376) were studied in 2017 in China. Physical activity (PA) was accelerometer-derived, while screen time (ST) and sleep duration were self-reported. Meeting the 24-h movement guidelines was defined as: 1) ≥ 60 min/day of moderate-to-vigorous PA; 2) ≤ 2 h/day of recreational ST; 3) 9-11 h/night of sleep. EF was assessed by the Wisconsin Card Sorting Test (WCST). Number of completed categories (CC), shifting efficiency (SE), non-perseverative errors (NPE), and failure to maintain set (FMS) were used to measure four processes of EF, respectively represented global performance, cognitive flexibility, efficiency in rule discovery, and sustained attention. Generalized linear mixed models (GLMM) were completed to explore the associations of meeting the PA, ST, and sleep duration recommendations with four processes of EF.ResultsStatistically significant positive associations were observed between the number of guidelines met, regarded as a continuous variable, with CC [β = 0.343 (95% confidence interval [CI]: 0.125, 0.561)] and SE [β = 4.028 (95% CI: 0.328, 7.727)], while number of guidelines met negatively related to NPE [β = - 4.377 (95% CI:-7.952,-0.802)]. Participants not meeting the two recommendations for PA and sleep duration had lower scores in CC [β = -0.636(95% CI:-1.125,-0.147)] and SE [β = -10.610 (95% CI:-18.794,-2.425)] compared with those meeting the two, suggesting inferior global performance and worse efficiency in rule discovery. However, ST recommendation had no significant association with any processes of EF.ConclusionMeeting more recommendations of the 24-h movement guidelines was associated with superior EF in children. Specifically, more PA and healthy sleep duration should be encouraged to promote children's EF.

Project description:BackgroundInsufficient physical activity, excessive recreational screen time, and inadequate sleep pose health risks in school-aged children and adolescents. The Canadian 24-Hour Movement Guidelines for Children and Youth advocate for balanced daily movement behaviours. This population-level study in British Columbia (BC), Canada, examined the proportion of young adolescents following these guidelines and how adherence correlated with their mental well-being.MethodsUsing cross-sectional self-report data from 26,974 grades 6-8 children (48% girls, mean age = 13.31) who had completed the Middle Years Development Instrument (MDI) in BC in 2023, we calculated the percentages of children meeting physical activity (at least 1 h daily), sleep (9 + hours for 5- to 13-year-olds, 8 + for > 13-year-olds), and screen time (no more than 2 h daily) recommendations. Eight groupings were created, indicating how many and which movement behaviour guidelines were met: none, sleep only, physical activity only, screen time only, physical activity and sleep, physical activity and screen time, sleep and screen time, and all three behaviours. Mean differences in depressive symptoms, optimism, and satisfaction with life scores across categories were estimated through sex-stratified linear mixed models, adjusting for covariates.ResultsFour percent of adolescents met all recommendations, while 15% met none. Meeting some or all recommendations was associated with higher levels of optimism and satisfaction with life, and lower levels of depressive symptoms compared to meeting none. Beneficial effects were overall larger for girls, and largest for depressive symptoms among girls meeting all recommendations versus none (-1.05, 95% CI [-1.14, -0.96]).ConclusionsAdherence to the Canadian 24-Hour Movement Guidelines was associated with higher levels of well-being, but most grades 6-8 adolescents in our study did not meet the recommendations. Given sex differences in meeting the movement behaviour recommendations, public health strategies need to consider targeted interventions aimed at improving adherence to these guidelines, particularly focusing on reducing recreational screen time and increasing physical activity.
