“…In addition, the results of this study confirmed that only 5.4% of Tibetan university students in high-altitude areas of China had a duration of physical exercise greater than 60 min/d. This result is consistent with the findings of many previous studies that the lack of physical activity among university students is significant ( Smout et al, 2023 ). The results of this study also indicate that the problem of insufficient physical exercise among university students does not change depending on the altitude.…”

“…The results of this study also confirmed that excess SSBs were positively associated with the development of psychological symptoms, i.e., the higher the number of SSBs, the higher the risk of developing psychological symptoms. In a study of Australian adolescents, SSBs were positively associated with the development of depression and anxiety ( Smout et al, 2023 ). Another study of Chinese adolescents also confirmed that SSBs were significantly associated with the development of psychological symptoms in adolescents ( Zhang et al, 2022 ).…”

BackgroundSugar-sweetened beverages (SSBs) and duration of physical exercise are strongly associated with physical health. Unfortunately, there are few studies focused on the association with psychological symptoms, let alone Tibetan university students at high altitudes in China.MethodsA stratified cluster sampling method was used to include 8,268 Tibetan university students aged 19–22 years in Qinghai and Tibet, both of which are high-altitude regions of China. Self-assessment questionnaires on SSBs, duration of physical exercise, and psychological symptoms were administered. The chi-square test and logistic regression analysis were used to analyze the associations among them.ResultsThe detection rate of psychological symptoms among Tibetan university students in high-altitude areas of China was 16.7%, with in girls (18.2%) higher than that in boys (14.8%), and the difference was statistically significant (χ2 = 11.73, p < 0.01). The proportion of SSBs for university students ≤1 time/week, 2–5 times/week, and ≥ 6 times/week were 54.2, 24.3, and 21.5%, respectively. The proportion of duration of physical exercise for >60 min/d was only 5.4%. Logistic regression analysis showed that compared with the SSBs ≤1 time/week group of university students, SSBs 2–5 times/week (OR = 1.45, 95% CI: 1.24–1.70) and ≥ 6 times/week (OR = 3.06, 95% CI: 2.62–3.57) had an increased risk of psychological symptoms (p < 0.001). In the reference group, the risk of psychological symptoms was also significantly increased in the group of university students with duration of physical exercise >60 min/d (OR = 2.08, 95% CI: 1.48–2.93), and the risk of psychological symptoms was also significantly increased in the group with duration of physical exercise <30 min/d (OR = 2.08, 95% CI: 1.48–2.93). The risk of psychological symptoms was also significantly increased in the university students with the duration of physical exercise <30 min/d (OR = 2.08, 95% CI: 1.48 ~ 2.93) group.ConclusionSSBs and exercise time may be important influences on the psychological symptoms of Tibetan university students at high altitudes in China. This study has important implications for mental health planning in universities in highland areas and may also provide guidance for mental health interventions for Tibetan university students.

“…Similarly, for adolescents whose anxiety symptoms improved over time, their sleep duration was no longer the shortest compared to increasing-symptom trajectories. This is not surprising, as studies examining the link between sleep duration and mental health have found a dose-response association that supports the positive association between the recommended 8-10 h of sleep for adolescents and emotional health 34,35 . Chronotype followed similar trends as sleep duration, as a later chronotype leads to later bedtimes during schooldays, shortening the sleep opportunity when wake-times are fixed 36 .…”

The COVID-19 pandemic has seen a rise in anxiety and depression among adolescents. This study aimed to investigate the longitudinal associations between sleep and mental health among a large sample of Australian adolescents and examine whether healthy sleep patterns were protective of mental health in the context of the COVID-19 pandemic. We used three waves of longitudinal control group data from the Health4Life cluster-randomized trial (N = 2781, baseline Mage = 12.6, SD = 0.51; 47% boys and 1.4% ‘prefer not to say’). Latent class growth analyses across the 2 years period identified four trajectories of depressive symptoms: low-stable (64.3%), average-increasing (19.2%), high-decreasing (7.1%), moderate-increasing (9.4%), and three anxiety symptom trajectories: low-stable (74.8%), average-increasing (11.6%), high-decreasing (13.6%). We compared the trajectories on sociodemographic and sleep characteristics. Adolescents in low-risk trajectories were more likely to be boys and to report shorter sleep latency and wake after sleep onset, longer sleep duration, less sleepiness, and earlier chronotype. Where mental health improved or worsened, sleep patterns changed in the same direction. The subgroups analyses uncovered two important findings: (1) the majority of adolescents in the sample maintained good mental health and sleep habits (low-stable trajectories), (2) adolescents with worsening mental health also reported worsening sleep patterns and vice versa in the improving mental health trajectories. These distinct patterns of sleep and mental health would not be seen using mean-centred statistical approaches.

“…Further demographic breakdown of this sample can be found elsewhere (Champion et al, 2022 ). Models used complete case analysis, and as the sample size is very large and missing data was negligible (below 5.4% for all dietary outcomes), no further examination of missing data was conducted as is standard practice (Smout et al, 2023 ). All analyses were conducted in Jamovi 1.6.16.…”

Parenting practices such as parental monitoring are known to positively impact dietary behaviours in offspring. However, links between adolescent‐perceived parental monitoring and dietary outcomes have rarely been examined and never in an Australian context. This study investigated whether adolescent‐perceived parental monitoring is associated with more fruit and vegetable, and less sugar‐sweetened beverages (SSB) and junk food consumption in Australian adolescents. Cross‐sectional data was collected as part of baseline measurement for a randomised controlled trial in 71 Australian schools in 2019. Self‐reported fruit, vegetable, SSB and junk food intake, perceived parental monitoring and sociodemographic factors were assessed. Each dietary variable was converted to “not at risk/at risk” based on dietary guidelines, binary logistic regressions examined associations between dietary intake variables and perceived parental monitoring while controlling for gender and socio‐economic status. The study was registered in ANZCTR clinical trials. The sample comprised 6053 adolescents (Mage = 12.7, SD = 0.5; 50.6% male‐identifying). The mean parental monitoring score was 20.1/24 (SD = 4.76) for males and 21.9/24 (SD = 3.37) for females. Compared to adolescents who perceived lower levels of parental monitoring, adolescents reporting higher parental monitoring had higher odds of insufficient fruit (OR = 1.03; 95% CI = 1.02–1.05) and excessive SSB (OR = 1.07; 95% CI = 1.06–1.09) intake, but lower odds of excessive junk food (OR = 0.96; 95% CI = 0.95–0.98) and insufficient vegetable (OR = 0.97, 95% CI = 0.96–0.99) intake. Adolescent dietary intake is associated with higher perceived parental monitoring; however, these associations for fruit and SSB differ to junk food and vegetable intake. This study may have implications for prevention interventions for parents, identifying how this modifiable parenting factor is related to adolescent diet has highlighted how complex the psychological and environmental factors contributing to dietary intake are.
