Overweight and obese children are at higher risk of developing serious health problems including type 2 diabetes, high blood pressure, asthma and other respiratory problems, sleep disorders and liver disease. They may also suffer from psychological effects, such as low self-esteem, depression and social isolation. Childhood obesity also increases the risk of obesity, noncommunicable diseases, premature death and disability in adulthood.

Sugar-sweetened beverage consumption is high in many parts of the world and is suggestive of poor dietary quality, as sugar-sweetened beverages contain sugars such as sucrose or fructose, often in large amounts, which contribute to the overall energy density of diets. The calories provided by sugar-sweetened beverages have little nutritional value and may not provide the same feeling of fullness that solid food provides. As a result, total energy intake may increase which can lead to unhealthy weight gain.

WHO has developed guidance on free sugars* intake, as shown below, based on the impact of free sugars intake on weight gain and dental caries. Current evidence suggests that increasing consumption of sugar-sweetened beverages is associated with overweight and obesity in children. Therefore, reducing consumption of sugar-sweetened beverages would also reduce the risk of childhood overweight and obesity.

* Free sugars include monosaccharides and disaccharides added to foods and beverages by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.
