Effect of a multicomponent intervention in postnatal mothers’ groups on meeting the Australian Physical Activity Guidelines for infants: protocol for a randomised controlled trial

Abstract

IntroductionGiven the importance of tummy time and the low levels of tummy time reported globally, there is a need for high-quality intervention strategies to promote tummy time. This study describes the protocol of a randomised controlled trial that aims to determine the effectiveness of a multicomponent intervention delivered in postnatal mothers’ groups in increasing infant tummy time.Methods and analysisA randomised controlled trial will be conducted. Eligible participants will be mothers and their infants attending postnatal mothers’ groups (New South Wales, Australia). Participants will be randomised to participate in either (1) infant tummy time intervention group (practice, education, WhatsApp) plus usual care; or (2) usual care group. Randomisation process and outcome assessors will be blinded. The intervention will comprise an online education and practice session (60 min) and 4 weeks of WhatsApp messaging (standardised, three times per week). Usual care will be attendance at a mothers group once per week for 3 weeks for information and support for ad hoc mother craft activities (standard practice provided by early childhood nurses for this local health district). The primary outcome will be the amount of infant tummy time using the GENEActiv accelerometer and a questionnaire (post intervention). The accelerometer will be worn on the right hip secured by an elastic belt around the waist. Wear and non-wear time will be classified using temperature and z-axis cut points as per previous research. This protocol paper presents the scientific background and proposed methods of the randomised controlled trial. Findings will inform the design of practically based strategies to inform clinicians, educators and parents about infant physical activity.Ethics and disseminationThe University of Wollongong and Illawarra Shoalhaven Local Health District Health and Medical Human Research Ethics Committee approved the study (2020/ETH02970). Dissemination plan is publication, staff training and conference presentations.Trial registration numberAustralian New Zealand Clinical Trials Registry ACTRN12621000575831; Pre-results.

Parental Practices and Environmental Differences among Infants Living in Upper-Middle and High-Income Countries: A Cross-Sectional Study

“…However, a study carried out in the United Kingdom, a high-income country, showed that just over 30% of families place their infants in the tummy time position [ 26 ]. Therefore, an Australian research group is studying strategies to make families aware and increase their adherence to adequate parental practices [ 27 ].…”
