am doing an introduction for research on

I need more information and her is the prof comment on my work. So, I need your help to complete what he wants.

I feel the background or literature review section needs more depth in terms of mentioning the existing studies that have assessed knowledge, attitude, practices regarding obesity, some may have focused on one or two… but we can still mention it.. also we have added body weight perception segment in our questionnaire, so this will be worthwhile writing about to. Finally, gaps in the literature needs to be outlined to highlight the significance of the study. Basically, the studies that you will mention in your section will be covered again in the discussion section, by another colleague, and to be compared with the study findings.

I also have some extra references that can help you.

Thank you
