FSSAI holds brainstorming sessions on sidelines of two-day Global Millets Conference
A new report released by the Economist Intelligence Unit (EIU), titled “Tackling obesity in ASEAN: Prevalence, impact, and guidance on interventions”, highlights that the prevalence of obesity and linked non-communicable diseases (NCDs) are costing Southeast Asia over US$10billion annually, in terms of healthcare costs.
The report analysed obesity in ASEAN through consumer and healthcare practitioner surveys, an intervention effectiveness analysis, and an economic impact assessment. ASEAN countries facing the highest costs of obesity in 2016 are: Indonesia (US$2-4billion) and Malaysia (US$1-2billion. The report finds that total costs of obesity represented as a percentage of national healthcare spending in the ASEAN-6 are highest in Malaysia (10–19 per cent) and Indonesia (8–16 per cent). They are lowest in Vietnam (1–3 per cent) and Thailand (3–6 per cent).
According to the EIU’s press release, workers with obesity-related conditions (including type 2 diabetes, cancer and stroke) in the ASEAN country sample are less productive than their healthy counterparts. The EIU said that these workers “effectively contribute to the economy for between four and nine (productive) years less than the working-age population average.
The EIU’s intervention effectiveness analysis evaluated various interventions targeted at individuals or the entire population sample, broadly categorised into: physiological, psychological, food-based or activity-based interventions. Interventions targeted at food and exercise show greatest promise in the fight against obesity. Amongst food-based interventions, low glycaemic index diets were found to be the most effective, based on the strength of the evidence base. Low-calorie, low-fat and low-carbohydrate diets have also shown promise as reliable, targeted interventions to combat obesity.
The EIU says that while food-based interventions cannot be directly legislated or regulated, “reducing portion sizes, taxing specific food types and implementing “choice environment” measures can be effective instruments. Based on the high magnitude of population impact, activity-based interventions showed great promise and are well suited to fight childhood obesity, which is an indicator of obesity as an adult according to the study.
Commissioned by the Asia Roundtable on Food Innovation for Improved Nutrition (ARoFIIN), the report is the first to carry out a detailed analysis of the economic impact of obesity in ASEAN.
ARoFIIN was set up in 2015 to leverage public-private partnership, to bring together experts from government, academia, industry and civil society sectors across Asia, in order to initiate and sustain regional, multi-stakeholder dialogue on the role of food innovation in tackling obesity and chronic disease in the region.
ARoFIIN is convened by the Health Promotion Board (HPB); the Agency for Science, Technology, and Research (A*STAR); the Singapore Institute for Clinical Sciences (SICS); and Food Industry Asia (FIA).
