A limitation of the majority of previous interventions has been the heavy reliance on intensive support from clinical providers limiting scalability.
The Cochrane review also grouped interventions of varying complexity and intensiveness. They were delivered in clinical maternity or community settings with a prescribed home component
utilising either individual or group-based counselling by dietitians, nutritionists or other health workers. The most intensive used intensive counselling and stepwise feedback
loops [19]. The least intensive was limited to regular selfweight recording [20].
