Fathers’ impact on the dietary and physical activity behaviours of children aged 0‐5 years Adam Walsh BAppSc (Human Movement) MNutr & Diet Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Deakin University December, 2017 Acknowledgements There are many people who have been with me, in one way or another, throughout my PhD journey. Firstly, I must thank my supervisors without whom I couldn’t have taken the road less travelled. Karen Campbell, who would have thought a shared flight home from DAA in Darwin would end like this? Thank you for giving me the opportunity to better myself. I truly value the support you have provided throughout my journey. Your constant looking out for me has not gone unnoticed and has been greatly appreciated. Kylie Hesketh, thank you for your constant support and guidance throughout my PhD. Your insights into the nuances of research and ability to guide me with them has helped me gain the confidence I needed to believe I could actually do this. Thank you for your promotion of my work – I know this has opened doors that perhaps would have otherwise remained closed. David Crawford, I’m not sure my academic journey would be as it is without your endless support. You’ve provided guidance, advice and ceaseless encouragement in my academic life, none more so than during my PhD. The opportunities that have been afforded me are, in large part, because of you. For that I am truly obliged. Adrian Cameron, in many ways you were the sounding board of my PhD. Always ready with some advice as well as endless patience for my seemingly never ending stats questions! Your pointed feedback always made me think about, and justify, what I was doing, which, in the end, probably made my PhD experience a (mostly) pleasurable one. There were many others who played their part ‐ it is truly a situation where the whole is greater than the sum of the parts. Sandrine Lioret, for working closely with me on my first paper; Sarah McNaughton, for encouraging me to believe in the same; Paige van der Pligt, for joining me on my qualitative journey; Claire Margerison, for holding the fort when my thesis called; and to my colleagues at IPAN, who were always willing to offer advice or guidance and ask me how things were going ‐ to you all I am indebted for your support. i To my family and friends…what can you say when you’ve received nothing but unconditional support for longer than you can remember? In your own way you have shaped me and I wouldn’t be who I am today without you. Finally, to my beautiful wife, Kim, and wonderful boys, Jack and Sam. Thank you for sharing this part of our amazing voyage and supporting me in whatever way you could. Mostly though, thank you for the pride you’ve shown in my work – to me that has been the greatest reward. My love and gratitude always. ii List of publications Published 1.
