“…Our study found that high school students were less likely to be physically active for the recommended amount of time compared to middle school students. This is consistent with other studies that show a decline in physical activity with age [60,61]. In addition to this, students with a normal BMI are more likely to meet the recommended physical activity hours on weekends.…”

Background: Unhealthy lifestyles among adolescents are reaching alarming levels and have become a major public health problem. This study aimed to assess the relationship between sleep time, physical activity (PA) time, screen time (ST), and nutritional literacy (NL). Methods: This cross-sectional online study involving adolescents aged 10–18 years was conducted in September 2020 in 239 schools in Chongqing, China. NL was measured using the “Nutrition Literacy Scale for middle school students in Chongqing (CM-NLS)”. According to the recommended by the Chinese dietary guidelines (2022), we divided the sleep time of junior high school students into <9 h and ≥9 h, high school students into <8 h and ≥8 h, divided the workdays into weekend PA time < 1 h and ≥1 h, and divided the workdays into weekend ST < 2 h and ≥2 h. The multinomial logistic regression model was used to examine the association. Results: A total of 18,660 adolescents (50.2% males) were included. The proportion of participants that were junior high school students and attended boarding schools was 57.2% and 65.3%, respectively. Compared with senior high school students, junior high school students had a higher level of NL. Whether on workdays or weekends, participants with sleep time ≥ 8/9 h, PA time ≥ 1 h, and ST < 2 h per day had higher levels of NL. On weekdays, participants who met the sleep time ≥ 8 h/9 h (OR = 1.48, 95% CI: 1.36, 1.62) and PA time ≥ 1 h (OR = 1.69, 95% CI: 1.59, 1.81) had higher reporting of NL levels. Conclusions: Sleep time, PA time, and ST were positively correlated with NL among adolescents, especially junior high school students.

“…This is concerning, especially when set in relation to the recent years increased engagement in obesogenic behaviors such as physically inactive and sedentary lifestyles [47,48] and dietary patterns characterized by high intakes of processed foods rich in salt and added sugars [49]. For instance, in Sweden, a significant increasing trend in screen time was observed in 4to-6-year-old children between 2018 and 2020, with a lower proportion of children watching < 1h of screen time per day [50]. In addition, an increased proportion of 4-to-6-year-old children that had 3-4 h of daily screen time was also observed [50].…”

BackgroundChildhood overweight and obesity is currently estimated to affect 39 million children under the age of five worldwide. After the COVID-19 pandemic, further increases have been observed in several countries including Sweden, where an increased incidence was observed in 3-and 4-year-old children, especially in disadvantaged areas. This development emphasizes the urgent need for population-based childhood obesity prevention interventions, and Swedish primary child health care provides an ideal setting for primary preventive efforts during the preschool years. However, thus far, previous child health care-based obesity prevention interventions have demonstrated limited effectiveness. As previous interventions also have been face-to-face delivered and thus resource-demanding; new, and scalable ways of delivering interventions also need to be evaluated. Mobile health or mHealth refers to the use of mobile devices for medical and public health practice and provides opportunity for development and dissemination of digital interventions for various purposes and populations at scale. This thesis reports the results of the MINISTOP 2.0 project, which covers the development and evaluation of the MINISTOP 2.0 digital intervention, from adaptation and translation of the intervention to Somali, Arabic and English (Paper I), to evaluation of real-world effectiveness within the Swedish primary child health care setting (Paper II) followed by exploration of user experiences and implementation aspects (Paper III) and a cost-consequence analysis of the intervention costs (Paper IV). AimThe overall aim of this thesis was to evaluate whether a 6-month parentoriented mHealth intervention (MINISTOP 2.0 app), embedded in the routine services of Swedish primary child health care, can be used to improve diet and physical activity behaviors, and decrease the prevalence of overweight and obesity in 2.5-to-3-year-old children. MethodsThe MINISTOP 2.0 project utilized a hybrid type 1 effectiveness-implementation study design to enable simultaneous evaluation and exploration of intervention effectiveness, user experiences and implementation aspects. Paper I: A qualitative exploration of user requirements in an app-based parental support intervention was conducted through three focus group interviews with Somali-(n = 5), Arabic-(n = 4), and Swedish-speaking

ImportanceThe beneficial effects of increasing outdoor physical activity time on children’s myopia onset and physical well-being are widely acknowledged. However, in countries with competitive educational systems, such as China, parents and school administrators may be relatively reluctant to increase the extracurricular physical activity time for children due to concerns that this action will compromise children’s academic performance.ObjectiveTo investigate whether additional extracurricular physical activity time after school compromises the academic performance of schoolchildren.Design, Setting, and ParticipantsThis cluster randomized clinical trial was conducted from October 2020 to June 2021 in Yudu, Jiangxi, China. Eligible children in grades 3 and 4 from 24 elementary schools were randomized to the intervention or control group. Primary analysis was conducted in the full sample using the intention-to-treat principle.InterventionsThe intervention group received 2 hours of after-school physical activity time outdoors on school days. The control group was free to arrange their after-school activity.Main Outcomes and MeasuresThe primary outcome was the between-group mean difference in mathematics test scores at the end of 1 academic year, with a noninferiority margin of −3.3 points. Standardized mathematics tests, physical fitness assessments (in reference to the 2018 National Physical Fitness Survey Monitoring Programme in China), and cycloplegic autorefraction were performed at baseline and the end of 1 academic year. Myopia was defined as a cycloplegic spherical equivalent refraction of −0.5 diopters or less in either eye.ResultsA total of 2032 children (mean [SD] age, 9.22 [0.62] years; 1040 girls [51.2%]) from 24 schools were randomized to the intervention group (12 schools; 1012 children) or control group (12 schools; 1020 children). The mean (SD) mathematics score at the end of 1 academic year was 78.01 (17.56) points in the intervention group and 77.70 (17.29) points in the control group. The adjusted between-group mean difference was 0.65 points (95% CI, −2.85 to 4.15). The adjusted between-group mean difference in physical fitness score was 4.95 points (95% CI, 3.56-6.34; P &lt; .001) and −1.90% (95% CI, −18.72% to 14.91%; P &gt; .99) in myopia incidence.Conclusions and RelevanceResults of this trial indicate that, compared with the control practice of free play after school, adding 2 hours of extracurricular physical activity outdoors after school was noninferior in academic performance and had superior efficacy in improving physical fitness.Trial RegistrationClinicalTrials.gov Identifier: NCT04587765
