Objective: To determine whether BMI differences observed at 5 years of age, from early intervention in infancy, remained apparent at 11 years.

Methods: Participants (n = 734) from the original randomized controlled trial (n = 802) underwent measures of body mass index (BMI), body composition (DXA), sleep and physical activity (24-h accelerometry, questionnaire), diet (repeated 24-h recalls), screen time (daily diaries), wellbeing (CHU-9D, WHO-5), and family functioning (McMaster FAD) around their 11th birthday. Following multiple imputation, regression models explored the effects of two interventions ('Sleep' vs.

This review aims to highlight the relative importance of cardiovascular disease (CVD) lifestyle-associated risk factors among individuals with inflammatory bowel disease (IBD) and examine the effectiveness of lifestyle interventions to improve these CVD risk factors. Adults with IBD are at higher risk of CVD due to systemic and gut inflammation. Besides that, tobacco smoking, dyslipidaemia, hypertension, obesity, physical inactivity and poor diet can also increase CVD risk.

Background: Although evening screen time is thought to impair subsequent sleep, current measures are limited to questionnaires which seem unlikely to accurately assess screen time in youth. Given the ubiquitous nature of digital devices, improving measurement of screen time is required before related health effects can be appropriately determined. The aim of this study was to objectively quantify screen time before sleep using video camera footage.

Article Synopsis
  • The study investigates how reallocating time among physical activity, sedentary behavior, and sleep affects obesity indicators like BMI and waist circumference across various age groups.
  • Researchers analyzed data from 9,818 participants using isotemporal substitution models to understand the implications of these behavior changes.
  • Results indicated that even small shifts of 10-30 minutes can significantly impact obesity, with reallocating moderate-to-vigorous physical activity (MVPA) to lighter activities or sedentary behavior having particularly detrimental effects.

Article Synopsis
  • The prevalence of physical activity, sedentary behavior, and sleep among 3- and 4-year-old children globally is unclear, highlighting the need for consistent data.
  • This study analyzed data from 14 cross-sectional studies across 33 countries to determine how many children met WHO guidelines for physical activity, screen time, and sleep over recent years.
  • Only 14.3% of the 7017 children studied met all the guidelines, with no significant differences found between countries with varying income levels regarding adherence to these health recommendations.
