“…In recent years, there has been a significant increase in screen time among adolescents, which may have adverse effects on their health. Research has found a significant correlation between screen time and obesity among children [ 40 , 41 ]. Khan et al [ 42 ] found that excessive screen time of any type was associated with sleep difficulties among adolescents.…”

Background: The risk of low back pain (LBP) increases steeply during adolescence, and adolescents with LBP are more likely to have low back pain in their adult years. This study aimed to investigate the dose-response relationship between daily screen time and the risk of low back pain among children and adolescents. Methods: PubMed, the Cochrane Library, Embase, and Web of Science were searched to collect relevant studies on daily screen time and the risk of low back pain from the establishment of the database up to December 2022. Two investigators independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. Stata16.0 was used to perform a dose-response metaanalysis and the methodological quality evaluation of the included studies. Results: The results of the meta-analysis showed that there is a positive correlation between daily computer time (OR = 1.32, 1.05-1.60), daily mobile phone time (OR = 1.32, 1.00-1.64), daily TV watching (OR = 1.07, 1.04-1.09) and the risk of low back pain, separately. The dose-response meta-analysis showed that there is a linear relationship between daily computer use and low back pain. The risk of low back pain increased by 8.2% for each 1-hour of daily computer use. Conclusions: Screen time is related to the risk of low back pain, and there is a linear relationship between daily computer use and the risk of low back pain. A number of strategic measures should be taken to prevent adolescents from developing severe low back pain.

“…The meta-analysis of Fang et al [36] showed that children and adolescents with an ST greater than 2 h/d had a 1.67 times higher risk of overweight and obesity than those with an ST of less than 2 h/d. Wu et al [37] further conducted a quantitative study. The results showed that the BMI of children and adolescents with an ST greater than 2 h/d was 0.7 kg/m 2 higher than that of children and adolescents with an ST of less than 2 h/d, and the ST of obese children and adolescents was 0.3 h/d higher than that of normal children.…”

Background: Since there is little knowledge about the 24-hour movement behaviors of Chinese children and adolescents, the purposes of this study were to investigate the proportion of Chinese children and adolescents meeting the 24-Hour Movement Guidelines and to further evaluate its relationship with overweight and obesity. Methods: A total of 440 children and adolescents aged 7–18 years from 7 cities in China were selected to measure physical activity using accelerometers, and sleep (SLP) and screen time (ST) using questionnaires. The data were analyzed with the independent T-test, Mann–Whitney U test, Cox–Stuart test, chi-square test, and logistic regression. Results: The proportion of Chinese children and adolescents meeting the overall 24-Hour Movement Guidelines was 7.3%. Boys (11.8%) were higher than girls (3.4%) (p < 0.001) and showed a downward trend with age (Ptrend = 0.03). The rates of overweight and obesity among children and adolescents who met the ST, MVPA + ST, ST + SLP, and MVPA + SLP + ST guidelines were 39%, 15%, and 36%, and 25% did not meet any guidelines. The rates of overweight and obesity among those who met 1, 2, and 3 guidelines were lower than the rate among those who did not meet any guidelines (odds ratio (OR) = 0.51, 95% confidence interval (CI): 0.22–1.17; OR = 0.32, 95% CI: 0.13–0.77; OR = 0.23, 95% CI: 0.07–0.81) and showed a decreasing trend (Ptrend = 0.006). Conclusions: The proportion of Chinese children and adolescents meeting the overall 24-Hour Movement Guidelines was low. The rate of overweight and obesity among children and adolescents who met the overall 24-Hour Movement Guidelines was the lowest compared with the rates among those who met any one or two. There was a dose–response relationship between the number of guidelines met and the overweight and obesity rate.

“…Increased screen time (characterized as the use of mobile phones, tablets, video games, and television [1]) is associated with an increased risk for the development of overweight and obesity in children and adolescents [2]. This association can be explained by replacing activities with higher energy expenditure by sedentary behavior [3] and by the greater consumption of high-calorie density foods such as ultra-processed foods [3,4].…”

Objective Analyze the association between screen use at night, food consumption at dinner, and evening snack in schoolchildren with and without overweight. Methods Cross-sectional study with a probabilistic sample of 1396 schoolchildren from 7 to 14 years of age from public and private schools of Florianópolis, Santa Catarina, Brazil. Dietary intake and frequency of screen use of the previous day were obtained through the questionnaire Consumo Alimentar e Atividades Físicas de Escolares (Food Consumption and Physical Activities of Schoolchildren). The association between screen use at night (exposure) and consumption of food groups (outcome) according to weight status was assessed using multivariate logistic regression. Results At dinner, schoolchildren without overweight who used screens once had a lower chance of consuming fruits and vegetables (OR: 0.62, p=0.017) compared to those who did not use screens. In addition, those who used screens twice were more likely to consume sweets (OR: 2.01, p=0.002), and screen use three times or more was inversely associated with beans (OR: 0.24, p=0.003) and meat, eggs, and seafood (OR: 0.35, p=0.011) consumption. Overweight schoolchildren who used screens three times or more were more likely to consume ultra-processed foods and pizza/hamburger/hot dogs (OR: 2.51, p=0.009). For the evening snack, it was observed that schoolchildren without overweight who used screens three times or more had a greater chance of consuming ultra-processed foods and pizza/hamburger/hot dogs (OR: 8.26; p=0.016). Conclusion Overweight and non-overweight schoolchildren who used screens were more likely to consume ultra-processed foods. Schoolchildren without overweight and who use screens more often at night are less likely to consume healthy foods.
