Notes:The data were extracted from the Register of Primary Health Care Visits (Avohilmo). The data are based on height and weight measurements taken at health care visits in child health clinics or school health care.
Definitions:The definition of obesity is based on the body mass index. ISO-BMI (a body mass index corresponding to the adults' body mass index) describes the body mass index that a child will have as an adult if his or her weight index remains at the current level in comparison with the child's peers. Child and adolescent with obesity is defined as having an age and sex adjusted body mass index (ISO-BMI) of 30 kg/m2 or higher. Child and adolescent with overweight (incl. obesity) is defined as having an age and sex adjusted body mass index (ISO-BMI) of 25 kg/m2 or higher.
