Frequently Asked Questions

Obesity is defined as abnormal or excessive fat accumulation that may impair health. In infants and children under 5 years of age obesity is assessed according to the WHO "Child growth standards" (weight-for-length, weight-for-height) and the WHO Reference for 5-19 years (body mass index-for-age)


In adults overweight is defined as the individual’s body mass index (BMI). This is a simple index of weight-for-height, defined as a person's weight in kilograms divided by the square of his or her height in metres (kg/m2). In adults BMI greater than or equal to 25 is overweight; and BMI greater than or equal to 30 is obesity

Obese infants and children are likely to continue being obese during adulthood and are more likely to develop a variety of health problems as adults. These include:


  •    Cardiovascular disease
  •    Insulin resistance (often an early sign of impending diabetes)
  •    Musculoskeletal disorders (especially osteoarthritis - a highly disabling degenerative disease of the joints)
  •    Some cancers (endometrial, breast and colon)
  •    Disability.



Supportive policies, environments, schools and communities are fundamental in shaping parents’ and children’s choices, making the healthier choice of foods and regular physical activity the easiest choice (accessible, available and affordable), thereby preventing obesity.
