Cost-effectiveness analyses are important tools to prioritise interventions for obesity prevention. Modelling facilitates evaluation of multiple scenarios with varying assumptions. This study "compares the cost-effectiveness of conservative scenarios for two commonly proposed policy-based population-wide interventions: front-of-pack ‘traffic-light’ nutrition labelling and a tax on unhealthy foods."
The Health Start Rating system is a voluntary front-or-pack labelling initiative endorsed by Australian government since 2014. This study "examines the health impact and cost-effectiveness of the Health Star Rating on pre-package food reformulation measured by changes in energy density between products with and without Health Star Rating and the authors evaluate the Health Star Rating system in different scenarios, in which was implemented on a voluntary or mandatory basis."
This systematic review "synthesised the cost-effectiveness evidence on interventions in policy, clinical and behavioural at individual, group and population level to control cardiovascular diseases and diabetes in South Asia."
The objective of this study was to examine "the effect of front-of-package nutrition labelling and sugary drink taxation on consumer beverage purchases."
The aim was "to assess public health strategies designed to tackle behavioural risk factors for chronic diseases that are closely linked with obesity, including aspects of diet and physical inactivity, in Brazil, China, India, Mexico, Russia, and South Africa."
This study examined "changes to consumer food purchases after the introduction of traffic-light labels with the aim of assessing the impact of the labels on the ‘healthiness’ of foods purchased." Through sales data from a major UK retailer in 2007, they analysed products in two categories (ready meals and sandwiches), investigating the percentage change in sales four weeks before and after traffic-light labels were introduced.
This study takes a "preliminary look at whether consumers might make more healthful food choices if nutrition labelling was mandated for the away from-home food sector, and how labelling requirements would in turn affect the foodservice industry."
