Multisectoral collaboration highlighted as key in delivering on the Sustainable Development Goals (SDGs), but still little is known on how to move from rhetoric to action. Cambodia has made remarkable progress on child health over the last decades with multisectoral collaborations being a key success factor. However, it is not known how country stakeholders perceive child health in the context of the SDGs or multisectoral collaborations for child health in Cambodia.

Through purposive sampling, we conducted semistructured interviews with 29 key child health stakeholders from a range of government and non-governmental organisations in Cambodia. Guided by framework analysis, themes, subthemes and categories were derived.

We found that the adoption of the SDGs led to increased possibility for action and higher ambitions for child health in Cambodia, while simultaneously establishing child health as a multisectoral issue among key child stakeholders. There seems to be a discrepancy between the desired step-by-step theory of conducting multisectoral collaboration and the real-world complexities including funding and power dynamics that heavily influence the process of collaboration. Identified success factors for multisectoral collaborations included having clear responsibilities, leadership from all and trust among stakeholders while the major obstacle found was lack of sustainable funding.

The findings from this in-depth multistakeholder study can inform policy-makers and practitioners in other countries on the theoretical and practical process as well as influencing aspects that shape multisectoral collaborations in general and for child health specifically. This is vital if multisectoral collaborations are to be successfully leveraged to accelerate the work towards achieving better child health in the era of the SDGs.
