- Very few early childhood interventions have observed sustained effects regarding television viewing and none have examined the mechanisms behind sustained intervention effects at long-term follow-ups. Thus, the aim of this study was to investigate potential mechanisms relating to the maintained intervention effect on television viewing at two long-term follow-ups in the Melbourne Infant Feeding Activity and Nutrition Trial (INFANT). INFANT was a cluster-randomised controlled trial. At the 2- and 3.5-year follow-ups, a total of 262 infant/mother pairs had complete information. Television viewing was assessed via a questionnaire at both follow-ups and six potential mediators were measured post-intervention (i.e. 15 months after baseline). Causal mediation analysis was conducted. At the 2- and 3.5-year follow-ups, the positive impacts of INFANT on maternal television viewing knowledge were maintained (B = 0.34 units; 95% confidence interval (CI95): 0.21, 0.48). An indirect effect of the intervention on reducing childrens television viewing time was observed at the 2- and 3.5-year follow-ups (B = -11.73 min/day; CI95: -22.26, -3.28 and B = -4.78 min/day; CI95: -9.48, -0.99, respectively) via improved maternal television viewing knowledge. Conclusion: The positive impacts of INFANT on maternal television viewing knowledge were maintained at both follow-ups, with better maternal knowledge associated with less television viewing time in their children. These results have implications for paediatricians and healthcare professionals as educating new parents early on regarding screen time may lead to the development of healthier screen time habits that are sustained through to the pre-school years.

- Aim We investigated psychological strengths and difficulties in a Swedish population of preschool children and analysed how these behavioural variables were related to body composition, cardiorespiratory fitness, physical activity levels, sedentary behaviour and diet. Methods Three hundred and fifteen boys and girls were recruited during 2014-2015. Body composition was measured using air-displacement plethysmography, and anthropometric measures were taken. Parents responded to questions about age, sex and educational attainment, diet, physical activity levels and smoking habits, as well as the Strengths and Difficulties Questionnaire (SDQ). Regression models were created to analyse associations between psychological variables, body composition and health behaviours. Results Hyperactivity scores were positively related to fat-free mass (beta = 0.20, P = .001) and moderate-to-vigorous physical activity (beta = 0.16, P = .003) and negatively associated with sedentary behaviours (beta = 0.18, P = .001), but showed no statistically significant associations with fat mass. Conclusion Our findings suggest that the adverse health consequences of hyperactivity on obesity and obesity-related health behaviours may be established after the preschool period. Questions about the time frame of contributing and modulating factors in obesity development are discussed.

- BackgroundThe restrictions associated with the 2020 COVID-19 pandemic has resulted in changes to young childrens daily routines and habits. The impact on their participation in movement behaviours (physical activity, sedentary screen time and sleep) is unknown. This international longitudinal study compared young childrens movement behaviours before and during the COVID-19 pandemic.MethodsParents of children aged 3-5years, from 14 countries (8 low- and middle-income countries, LMICs) completed surveys to assess changes in movement behaviours and how these changes were associated with the COVID-19 pandemic. Surveys were completed in the 12months up to March 2020 and again between May and June 2020 (at the height of restrictions). Physical activity (PA), sedentary screen time (SST) and sleep were assessed via parent survey. At Time 2, COVID-19 factors including level of restriction, environmental conditions, and parental stress were measured. Compliance with the World Health Organizations (WHO) Global guidelines for PA (180min/day [>= 60min moderate- vigorous PA]), SST (<= 1h/day) and sleep (10-13h/day) for children under 5years of age, was determined.ResultsNine hundred- forty-eight parents completed the survey at both time points. Children from LMICs were more likely to meet the PA (Adjusted Odds Ratio [AdjOR]=2.0, 95%Confidence Interval [CI] 1.0,3.8) and SST (AdjOR=2.2, 95%CI 1.2,3.9) guidelines than their high-income country (HIC) counterparts. Children who could go outside during COVID-19 were more likely to meet all WHO Global guidelines (AdjOR=3.3, 95%CI 1.1,9.8) than those who were not. Children of parents with higher compared to lower stress were less likely to meet all three guidelines (AdjOR=0.5, 95%CI 0.3,0.9).ConclusionPA and SST levels of children from LMICs have been less impacted by COVID-19 than in HICs. Ensuring children can access an outdoor space, and supporting parents mental health are important prerequisites for enabling pre-schoolers to practice healthy movement behaviours and meet the Global guidelines.
