“…Schools are embedded in their surrounding communities (Haggis, 2010; Rosas, 2017), and SHPI can create complex dynamics among different partners (school sector, health sector and community stakeholders) and at various hierarchical levels (Rosas, 2017). To engage productively with these challenges, SHPI should be implemented collaboratively (Mukamana and Johri, 2016; Pinto et al, 2017; Rosas, 2017; St Leger, 2004; Turunen et al, 2017). Intersectoral collaboration, which can be defined as a collective action in which several stakeholders with common goals perform different roles, is therefore necessary (Adeleye and Ofili, 2010) to improve intervention efficiency and effectiveness, and ensure its sustainability (Adeleye and Ofili, 2010; Pommier and Ferron, 2013).…”
