The burden of malnutrition at a glance
Tonga is 'on course' to meet three of the global nutrition targets for which there was sufficient data to assess progress.
Tonga is 'on course' to meet three targets for maternal, infant and young child nutrition (MIYCN). No progress has been made towards achieving the target of reducing anaemia among women of reproductive age, with 28.5% of women aged 15 to 49 years now affected. Meanwhile, there is insufficient data to assess the progress that Tonga has made towards achieving the low birth weight target, nor is there adequate prevalence data. No progress has been made towards achieving the exclusive breastfeeding target, with 52.2% of infants aged 0 to 5 months exclusively breastfed. Tonga is 'on course' to meet the target for stunting, with 2.2% of children under 5 years of age affected. Tonga is also 'on course' for the target for wasting, with 1.1% of children under 5 years of age affected. The prevalence of overweight children under 5 years of age is 11.2% and Tonga is 'on course' to prevent the figure from increasing.
Tonga has shown limited progress towards achieving the diet-related non-communicable disease (NCD) targets. The country has shown no progress towards achieving the target for obesity, with an estimated 57.9% of adult (aged 18 years and over) women and 45.5% of adult men living with obesity. Tonga's obesity prevalence is higher than the regional average of 31.7% for women and 30.5% for men and among the highest in the world. At the same time, diabetes is estimated to affect 30.3% of adult women and 25.2% of adult men.

Notes: Progress towards the maternal, infant and young child nutrition (MIYCN) and diet-related non-communicable disease (NCD) global nutrition targets is classified as ‘on course’ if the target is met, ‘some progress' or ‘no progress or worsening’. MIYCN targets include anaemia among women of reproductive age (15–49 years), infants with low birthweight, exclusive breastfeeding among infants under 6 months of age, and childhood stunting, wasting and overweight. NCD targets include adult obesity and diabetes, raised blood pressure and sodium intake. Obesity and diabetes are based on age-standardised modelled estimates for adults aged 18 years and older, using the WHO standard population; they are reported by sex due to limitations in data availability. Anaemia and low birthweight are also based on modelled estimates. The specific targets set are: 40% reduction in the number of children under 5 years of age who are stunted; 50% reduction of anaemia in women of reproductive age; 30% reduction in low birth weight; no increase in childhood overweight; increase the rate of exclusive breastfeeding in the first 6 months to at least 50%; reduce and maintain childhood wasting to less than 5%; 30% relative reduction in the mean population intake of salt/sodium by 2025; 25% relative reduction in the prevalence of raised blood pressure or contain the prevalence of raised blood pressure, according to national circumstances; and halt the rise in obesity and diabetes. The methodologies for tracking progress differ across targets. See Methodology for more information on the indicators.
Infant and young child feeding
Prevalence of infant and young child feeding indicators

Notes: Prevalence (%) estimates are presented for infants and young children aged 0–23 months (age varies by indicator). Location is classified as ‘urban’ or ‘rural’ (as defined in the survey). Education refers to the educational level of the mother and is classified as ‘none or primary’ or ‘secondary or higher’. Wealth is asset-based wealth scores at the household level, classified as quintiles: ‘lowest’, ‘second lowest’, ‘middle’, ‘second highest’ and ‘highest’. See Methodology for more information on the indicators.
Dietary intakes of key foods and nutrients in adults aged 20 years and over compared against minimum and maximum targets
Source: Tufts University. Global Dietary Database. Published online 2019. Available at: https://www.globaldietarydatabase.org/data-download. Accessed 6 September 2021.
Notes: Intakes are reported in grams per day (g/d) for all dietary factors. Intakes are based on modelled estimates for adults aged 25 years and older. The dietary factors have been selected as those diet components that have a statistically significant relationship with at least one disease endpoint that can be generalisable to all populations. Recommended intake targets were determined by the EAT-Lancet Commission on healthy diets from sustainable food systems. This includes minimum recommended intakes of health promoting food groups (fruits, vegetables, legumes, nuts and wholegrains) and maximum recommended intakes of food groups with detrimental health and/or environmental impacts (red meat, dairy, and fish). Ideal intake for each food is within the shaded area of the graph.

Notes: Country with food-based dietary guidelines in 2018, sugar-sweetened beverage tax in 2017 and all other policies in 2019. 'Policy' is defined as a specific official decision or set of decisions designed to carry out a course of action endorsed by a political body, including a set of goals, priorities and main directions for attaining these goals, including legislation and product reformulation mandates. 'Strategy' is defined as a long-term plan designed to achieve a particular goal. Action plan is defined as a scheme or course of action, which may correspond to a policy or strategy, with defined activities indicating who does what, when, how and with what resources to accomplish an objective. ‘Operational’ describes a policy, strategy or plan of action being used and implemented in the country, with resources and funding available to implement it. ‘Multisectoral’ applies to a policy, strategy or plan of action that involves different sectors (e.g., health, agriculture, education, finance). See Methodology for more information on the indicators.
