“…This finding is consistent with research among general adolescent populations that shows that more than half of US 16-year-olds regularly get less than 7 hours of sleep and that US adolescents commonly have schedules that restrict their sleep during the school year; more research is needed to further understand how inadequate sleep in young athletes may affect health, well-being, and performance. 6,24,29,36,40,42,43 This study also noted that 55% reported having felt physically exhausted and 45% felt mentally exhausted from basketball participation within the past year. Although multivariate analysis suggested that girls were more likely to report physical exhaustion, and less than 8 hours of sleep during the school year was also associated with this outcome, this question was added late in the survey period and the observations were thus limited to a subsample (n = 205) of the study group.…”

Age of Early Specialization, Competitive Volume, Injury, and Sleep Habits in Youth Sport: A Preliminary Study of US Youth Basketball

et al. 2021

Background: Concerns for youth sports in the United States often focus on early sport specialization, overemphasis on competition, injuries, and burnout. Little research has addressed relationships among the preceding and other concerns, including time away from organized sport, sleep, and perceptions of physical and psychological well-being. Hypothesis: There is an association between reported competitive gameplay volume and specialization, injury, and fatigue among elite youth basketball players. Study Design: Cross-sectional study; convenience sample. Level of Evidence: Level 4. Methods: An anonymous questionnaire was administered to a convenience sample of youth basketball players between 13 and 18 years of age from across the United States. Participants were queried about multiple factors, including the extent of their participation in organized basketball and other sports, time away from organized basketball, injury, sleep, and feelings of exhaustion related to basketball participation. Results: A total of 772 participants (145 girls, 627 boys) completed a survey. All participants played for a select or elite club basketball team and/or a high school basketball team. Overall, 49% played more than 50 games within the past year. A total of 73% were specialized in basketball, 58% prior to age 14 years, and 35% prior to age 11 years. In all, 70% reported less than 1 month away from organized basketball within the past year, and 28% reported no time away. A total of 54% reported sleeping less than the recommended 8 hours each night during the school year. Within the prior year, 55% reported feeling physically exhausted and 45% reported feeling mentally exhausted from basketball. Regression analysis did not find any significant relationships between early specialization prior to age 14 years and basketball-related injury or feelings of mental or physical exhaustion. Conclusion: In this select group of youth basketball players, the majority specialized in basketball prior to age 14 years and reported a large number of competitive events with little time away from organized basketball. Clinical Relevance: The results from a sample of highly competitive youth basketball players indicate issues that warrant further attention and research regarding the potential impact of specialization, frequent competitions, lack of time away from organized sport, and perceptions of well-being in young athletes.

“…Qualitative analysis of the studies that could not be included in the meta‐analysis showed a statistically significant positive association between social jetlag and BMI (Cetiner, Yildirim, & Kalyoncu, 2021; Johnsen, Wynn, & Bratlid, 2013; Liang et al, 2022), as well as a positive correlation between social jetlag and BMI (Karadag & Yilmaz, 2021). Other studies (Berry et al, 2021; Constantino et al, 2021; Kelly et al, 2022; Larcher et al, 2016; Rusu, Ciobanu, Bala, Cerghizan, & Roman, 2019) showed no statistically significant difference in BMI between those with and without social jetlag.…”

This study aims to determine the association between social jetlag and parameters of metabolic syndrome and type 2 diabetes (T2D) in a systematic review and meta-analysis.A systematic literature search was conducted in PubMed/Embase/Scopus until May 2022. Included studies described an association between social jetlag and parameters of the metabolic syndrome and/or T2D, were available full text and written in English or Dutch. Data extraction and quality assessment were performed on pre-piloted forms independently by two reviewers. Results were meta-analysed using random-effects analysis. A total of 6,290 titles/abstracts were screened, 176 papers were read full-text, 68 studies were included. Three studies were rated as low quality, 27 were moderate, and 38 were high quality. High quality studies showed that having social jetlag compared to no social jetlag was significantly associated with higher body mass index in 20 studies (0.49 kg/m 2 , 95% confidence interval [CI] 0.21-0.77; I 2 = 100%), higher waist circumference in seven studies (1.11 cm, 95% CI 0.42-1.80; I 2 = 25%), higher systolic blood pressure in 10 studies (0.37 mmHg, 95% CI 0.00-0.74; I 2 = 94%) and higher glycated haemoglobin in 12 studies (0.42%, 95% CI 0.12-0.72; I 2 = 100%). No statistically significant associations were found for obesity, abdominal obesity, high-and low-density lipoprotein levels, cholesterol, triglycerides, diastolic blood pressure, hypertension, fasting glucose, homeostatic model assessment for insulin resistance, metabolic syndrome or T2D. Sensitivity analyses did not reduce heterogeneity. Despite substantial heterogeneity, social jetlag is associated with certain parameters of the metabolic syndrome and T2D, but not with prevalent metabolic syndrome or T2D. These findings should be interpreted with caution as the level of evidence is low and mostly based on cross-sectional data. Longitudinal studies are needed to further assess the direction of causality.

“…All of them were conducted among adolescents. Two of them (Berry et al, 2021; Hamre et al, 2022) did not find an association between social jetlag and physical activity, whereas one study reported that adolescents with mild social jetlag (1–2 h) were more physically active than those with social jetlag of more than 2 h (Cetiner et al, 2021).…”

“…While an integrated approach is advocated to maximise health benefits, it should not be neglected that these behaviours interact with each other. For example, insufficient sleep may make children less physically active and more sedentary in the daytime because of a feeling of tiredness (Berry et al, 2021; Taheri, 2006). Moreover, a longer screen time, in particular computer use, is associated with a shorter sleep duration and delayed sleep timing (Hale & Guan, 2015).…”

SummarySleep and daytime movement behaviours occur co‐dependently with each other within a finite 24 h day. Sleep parameters other than sleep duration, such as social jetlag and chronotype, have been linked to health problems and unhealthy behaviours among children and adolescents. Given the increasing number of studies examining sleep timing/chronotype and weight‐related behaviours, including physical activity and sedentary behaviour, in the past decade, this systematic review and meta‐analysis collated and evaluated the evidence on the relationships of social jetlag and chronotype with physical activity and sedentary behaviour among children and adolescents aged 3–17 years. Seven databases were searched on 16 March 2022, and 52 studies were identified as eligible for inclusion, 47 of which were suitable for the meta‐analysis. A positive association was found between social jetlag and screen media use (r = 0.14, 95% CI: 0.04–0.24; I2 = 96%; p = 0.008). The morning chronotype was associated with a higher level of physical activity and a lower level of sedentary behaviour than the evening chronotype. No relationship was found between social jetlag and physical activity. The magnitude of heterogeneity among the included studies was high. Further experimental studies are urgently required to understand how circadian preference or misalignment affects activity behaviours. Interventions to promote an active lifestyle in young populations should consider their circadian preference, especially among individuals with the evening chronotype.
