academic research topic

Hello, I am seeking for guidance on the following research topic I have formulated out of my passion to do something related to emergency nutrition, CMAM. Out of my 11/2yrs experience I found as if there is some relationship between caregivers knowledge level on nutrition rehabilitation process and their cooperation in nutrition management of SAM and length of stay/recovery period of children which has led me formulation this topic: {Impact of carer's nutrition rehabilitation process knowledge on recovery period of children with severe acute malnutrition }. Where do I get such related studies for literature review? Do you feel it worth undertaking? Or where exactly do I need to focus on? Regards
