Exploring Parents’ Message Receipt and Message Enactment of the World’s First Integrated Movement Behaviour Guidelines for Children and Youth

The Canadian 24-Hour Movement Guidelines for Children and Youth are novel in how they integrate the guideline recommendations for the full continuum of movement behaviours, from sleep to vigorous physical activity. Research suggests that the integrated guidelines strategy is perceived favourably, and this study is the first to compare this strategy to traditional segregated guidelines on its effectiveness to disseminate health information. Specifically, this study explored (1) the influence of the integrated guidelines strategy on parents' message receipt and message enactment to support their child meet the guidelines, and (2) the relationship between message receipt and message enactment in a youth movement behaviour context. In this prospective randomized experiment, parents (n= 162) were randomized to read integrated, segregated, or control guidelines and complete pre, post, and 2-week follow-up surveys. Repeated-measures ANOVAs revealed significantly higher message enactment outcomes among participants in the integrated guidelines group (p< .05). Message receipt and enactment outcomes were significantly correlated (r> .171, p< .05). These findings highlight that parents' initial receipt of a message is important for subsequent behaviour change in a youth movement behaviour context. Furthermore, the integrated guidelines strategy may have an advantage in promoting guideline update and should continue to be explored.
