While several efforts have recently been undertaken to examine interrelationships among multiple health behaviours (McEachan, Lawton, & Conner, 2010;Nudelman & Shiloh, 2015;Sniehotta, Presseau, Allan, & Ara ujo-Soares, 2016), studies in this vein have yet to identify core behaviours that are highly connected and thus are likely to be particularly useful targets for interventions.
