“…In regard to study length, actigraphy should record a subject for at least 7 days, but 14 days is recommended as it can capture weekday versus weekend StDev differences, more accurately reflect habitual sleep patterns, and prevent StDev and interdaily stability metrics from overestimating sleep irregularity [26]. On a positive note, most studies reviewed herein did record actigraphy data for 7 [32, 33, 46–49, 62, 69, 71, 73, 75, 77, 84, 87, 90] to 14 [85] days, as suggested by Fischer and colleagues [26]. Future studies should analyze their parameters and select the most accurate generalizable metric (or metrics) to understand which is most predictive for obesity, cardiovascular, and metabolic outcomes.…”

“…The existing evidence indicates that young Black females show greater sleep variability when compared with males and non‐Hispanic White adolescents [39, 49]. He and colleagues additionally found racial/ethnic disparities in sleep variability, as adolescents who identified as primarily Black/African American and Hispanic/Latinx experienced greater day‐to‐day sleep variability as compared with non‐Hispanic White adolescents, and this disparity was more pronounced among adolescents with high caloric intake [87]. There is a need for greater research addressing sex/gender and racial/ethnic differences in the association of sleep variability with cardiometabolic health.…”

Objective: Adolescence is a developmental stage of critical changes in sleep and its circadian timing when the contribution of abnormal sleep variability (amount) and sleep regularity (timing) to obesity and its associated adverse cardiometabolic health outcomes appears to increase. The aim of this study was to summarize findings from studies conducted in adolescents examining both sleep variability and regularity in relation to obesity and cardiometabolic health. Gaps in research and potential causal pathways that future studies should examine are highlighted. Results: Nightly deviations in sleep duration and sleep midpoint appear to contribute to the development of obesity and associated adverse cardiometabolic outcomes in youth. Studies show that increased sleep variability and irregularity are associated with obesity, decreased physical activity, dysregulated eating and inadequate diet, metabolic dysfunction, impaired cardiac autonomic balance, and elevated blood pressure in adolescents. Conclusions: A stable circadian timing of sleep is essential to the overall physical well-being of youth. Emerging evidence supports that sleep variability and circadian misalignment, including sleep irregularity, contribute to adverse obesity-related health outcomes early on in adolescence. Future studies should focus on the underlying behavioral and biological mechanisms in the causal pathway between day-to-day deviations in the amount and timing of sleep and obesity.

“…This result could be explained by the existence of certain key nutrients involved in both sleep and mental regulation, such as polyunsaturated fatty acids, vitamin C, and vitamin B [37,38]. Calorie-rich food is another common risk factor for both sleep and depression [39][40][41]. It should be highlighted that the current postpartum dietary practice did not completely fit the current evidence-based dietary guidelines and could therefore lead to an insufficient intake of polyunsaturated fatty acids, vitamin C, and vitamin B and an excessive intake of energy, which are the mental health-related dietary components mentioned above [20].…”

Conflicting results of Chinese traditional postpartum practices have aroused concerns over their health effects. The role of postpartum practices in postpartum depression (PPD) is still a matter of discussion, especially from a dietary practice point of view. The current study was designed to (1) explore the association between postpartum practices and PPD, (2) to identify the dietary pattern related to PPD, and (3) to identify the possible pathways among postpartum practices and PPD. This study is part of the YI Study, which was a cross-sectional study conducted in 10 cities in China. Data for 955 postpartum women were used in the current analysis. The Edinburgh Postnatal Depression Scale (EPDS-10) was used to evaluate PPD with a cutoff value of 9. Postpartum practice was based on the participants’ self-reported practices. Individual practices were recorded and categorized as dietary and non-dietary practices. The dietary pattern was identified based on the food intake frequencies of 25 food groups using the method of reduced rank regression. Structural equation modeling was used to explore the potential pathways between postpartum practices and PPD. The current study observed significant associations between postpartum practices and PPD (Adjusted OR = 1.41, 95% CI: 1.04–1.90). A similar trend was also found between dietary postpartum practices and PPD (Adjusted OR = 1.39, 95%CI: 1.03–1.88) but not for non-dietary practices and PPD (Adjusted OR = 1.26, 95%CI: 0.92–1.75). A PPD-related dietary pattern was identified with the characteristics of a high intake of meat and eggs and a lower intake of vegetables, mushrooms, and nuts. This dietary pattern was significantly associated with a higher chance of adhering to postpartum practice (Adjusted OR = 1.26, 95% CI: 1.10–1.44). Based on the pathway analysis, this study also observed the association between postpartum practices and PPD, and the association between dietary practices and PPD were both mediated by sleep quality. In conclusion, this study demonstrated that a substantial proportion of women in modern China experience traditional postpartum Chinese practices and that either overall or dietary-related postpartum practices are associated with a higher risk of PPD. The current dietary practices in postpartum rituals may play an important role in developing PPD. A culturally embedded, science-based dietary guideline is required to help women to achieve both physical and psychological health in the postpartum period.

ImportanceAlthough racial and ethnic disparities are well documented in children’s mean levels of sleep, particularly duration, evidence is mixed for sleep variability, an important sleep dimension of growing interest. Most research has also focused on comparisons of Black and White children, with limited attention to sleep variability disparities among other racially and ethnically minoritized groups such as Asian, Latinx, and multiracial children.ObjectiveTo investigate racial and ethnic disparities in children’s mean levels of sleep and variability of sleep across multiple dimensions and diverse racial and ethnic groups using actigraphy data.Design, Setting, and ParticipantsThis cross-sectional study used data from the Adolescent Brain Cognitive Development (ABCD) study, a national cohort study, from 21 study sites across the US. ABCD participants were recruited at baseline (2016-2018) using a multistage, stratified, probability sampling method. The current study used a subsample with reliable actigraphy data collected at 2-year follow-up (2018-2020). Data analysis occurred from July 2023 to October 2024.ExposuresParent-reported race and ethnicity at baseline. Sociodemographic, health, and contextual covariates of sleep were also included.Main Outcomes and MeasuresActigraphy-assessed mean levels of sleep and sleep variability across multiple dimensions (duration, bedtime, risetime, efficiency, and latency) over 3 weeks.ResultsThe analytic sample included 3868 children (mean [SD] age, 11.50 [0.67] years; 1913 female [49.5%]), of whom 104 (2.7%) were Asian, 347 (9.0%) were Black or African American, 801 (20.7%) were Latinx, 356 (9.2%) were multiracial, and 2260 (58.4%) were White. Asian, Black, Latinx, and multiracial children exhibited shorter sleep duration and later bedtime than White children. Importantly, compared with White children, bedtime variability was greater among Asian (β = 0.04; 95% CI, 0.01 to 0.07; P = .02), Black (β = 0.11 95% CI, 0.08 to 0.15; P &lt; .001), Latinx (β = 0.08; 95% CI, 0.05 to 0.12; P &lt; .001), and multiracial children (β = 0.08; 95% CI, 0.05 to 0.11; P &lt; .001). Similarly, risetime variability was greater among Asian (β = 0.04; 95% CI, 0.01 to 0.07; P = .01), Black (β = 0.08; 95% CI, 0.04 to 0.12; P &lt; .001), and Latinx (β = 0.06; 95% CI, 0.02 to 0.10; P &lt; .01) children in comparison with White children. Black children exhibited the most profound disparities across mean levels (duration and bedtime) and variability of sleep (duration, bedtime, risetime, and efficiency) than other groups. Asian and multiracial children also exhibited some disparities sleep duration, efficiency, and efficiency variability, when compared with Latinx children.Conclusions and RelevanceIn this cross-sectional study of children’s sleep disparities, racially and ethnically minoritized children exhibited disparities in mean levels and variability of sleep compared with their White peers. These findings suggest that policies and practices should target multiple sleep dimensions among diverse racial and ethnic groups to promote equitable pediatric sleep health.
