In 2017, the Australian Government funded update of National Physical Activity Recommendations for Children 0–5 years, with intention that they be an integration movement behaviours across 24-h period. The benefit Australia was it could leverage research in Canada development their guidelines early years. Concurrently, Grading Assessment, Development and Evaluation (GRADE) working group published a model to produce based on adoption, adaption and/or de novo using GRADE evidence-to-decision...

Parents influence their children's weight-related behaviours through parenting practices, which are often a focal point of obesity prevention interventions. This study examined associations maternal concern about child's weight, dietary intake, physical activity, and media use with food, practices. Mothers (n = 310) reported level regarding weight related practices when child was 5 years age as part the Melbourne Infant Feeding Activity Nutrition Trial (InFANT) Program. We used linear...

Abstract Background The few health behavior interventions commencing in infancy have shown promising effects. Greater insight into their longer-term benefits is required. This study aimed to assess post-intervention effects of the Melbourne INFANT Program child age 5y on diet, movement and adiposity. Methods Two 3.5y follow-up (2011–13; analyses completed 2019) participants retained at its conclusion (child ~ 19 m; 2008–10) was conducted. a 15-month, six session program delivered within...

Abstract Background Toddlerhood (2–3 years) is a crucial period for the development of physical activity, sleep, and emotional self-regulation skills. Although there growing evidence positive associations between in school-aged children, toddlers remain unclear. Thus, this study aimed to examine association toddlers. Methods Baseline data from 1350 (2.2 ± 0.33 year) Let’s Grow randomised controlled trial were used. Toddlers’ total activity (TPA) moderate- vigorous-intensity (MVPA) assessed...

Physical activity (PA) decreases and sedentary time (SED) increases across childhood, with both behaviours tracking. However, no studies have examined how accumulation patterns of PA SED (i.e., prolonged bouts, frequency breaks in time) change track over time. The aim this study was to investigate longitudinal changes tracking total volume SED, light-intensity (LPA), moderate-intensity (MPA), vigorous-intensity (VPA) among boys girls.In 2008/09 (T1), children HAPPY (3-5y; n = 758) Melbourne,...

Abstract Background Canada, Australia, the World Health Organization and other countries have released 24-hour movement guidelines for early years which integrate physical activity, sedentary behaviour, sleep, focusing on supporting children to achieve a healthy day. The guideline evidence synthesis, however, highlighted dearth of high-quality evidence, particularly from large-scale studies.

Introduction Child eating behaviours develop through interactions between the child’s characteristics, psychological factors and social environment this affects diet weight. To examine currently existing birth cohort studies examining child behaviours, a review was conducted. There are no cohorts that concurrently dietary intake, growth parental feeding practices from into early childhood. Therefore, primary objective of Longitudinal Assessment Children’s Eating (LACE) study is to...
