Monitoring and surveillance system of unhealthy products marketing is a part of the study on the situation of unhealthy products marketing control. Unhealthy products of this study included food, breast milk substitutes, tobacco and alcoholic beverage. The objective of this study was to analyze the gaps of and opportunities for monitoring and surveillance system of unhealthy products marketing. Literature review and interview with the stakeholders were undertaken. Searches were conducted through government, academia, and civil society database from 2012 to 2017 via Google search engine. Purposive sampling was used to select the key informants from government agencies, academia, and civil society for interview. Framework of analysis was the guideline of surveillance system of the Center for Policy Development, and Non-Communicable Disease Control Strategy Program, Department of Disease Control. The study found similar monitoring and surveillance systems including active and passive monitoring systems for all 3 types of products (except breast milk substitutes), but had different participations from other sectors. The control of food marketing lacked participation from academia, and civil society. Monitoring and surveillance system of alcohol marketing did not collaborate with other ministries such as the National Broadcasting and Telecommunication Commission, Ministry of Digital Economy and Society. Monitoring and surveillance system of tobacco marketing had many actors but with no coordinating agency. Monitoring and surveillance system of unhealthy products marketing including marketing of infant and baby food was recently set up. Therefore, there should be further evaluation on efficiency of these monitoring and surveillance systems.
