BMI and Adiposity in Children

In health surveillance, body mass index (BMI)-for-age (BA) is a well-established indicator for pediatric obesity. The WHO rec- ommends that obesity in school-age children and adolescents is defined as a BA z-score (BAZ) of >2 (equivalent to BMI 30 kg/m2 at 19 years), and overweight as BAZ >1 (equivalent to BMI 25 kg/m2 at 19 years).1,2 However, obesity-related adverse health effects are related to an excess of body fat, not an excess of body weight, and there is consistent evidence that high BAZ correctly identifies individuals with highest body fatness and highest risk of co-mor- bidities, but fails to identify children who are excessively fat but who do not have high BAZ.3–6 It has high specificity (low false positive rate), but low to moderate sensitivity (moderate to high false negative rate).7 The high specificity is an advantage for clin- ical use, but low to moderate sensitivity is problematic for public health applications, such as obesity surveillance, since relatively large numbers of children with high body fat content will “test negative.”8 It is estimated that 25%–50% of children and ado- lescents defined as having a healthy BMI-for-age will also have excess body fat.5,6 Most of the evidence comes from systematic reviews based largely on European and Western populations.9 In many other populations, the bias associated with the use of BMI is worse, leading to more pronounced underestimates of obesity prevalence, and complicating global comparisons.
