Medical College Students' Responds to Menu Labeling With or Without Nutrition
Aperçu de l'étude
Statut
Les conditions
Description détaillée
- The investigators improved the previous photographs-based dietary assessment tools and utilized the improved approach to evaluate participants' calorie and nutrients intake.
- A pre-post non-controlled study design was implemented in the medical college and was divided into three stages: just recording the dietary selection in the three meals daily, recording the dietary selection with the provision of menu labeling accompanying with or without nutrition education. The investigators adopted photographs-based dietary assessment tools and a mobile phone application 'WeChat' was utilized as the photographs and nutrition knowledge transfer platform. Two professional researchers respectively read the received photographs and calculated participants' calorie and nutrients intake.
