Following the publication of this article, the authors noted the following errors:

In line 14 of the Abstract, the figure $14.1 billion should be $2.9 billion; in line 16, “further reinforce efforts” should instead be “further efforts.”

On page 3, in the second paragraph of the first column, the last two sentences should read: “Extrapolated to the nation, $1.6 billion (97.5% CI: $0.8–3.0 billion) in additional outpatient expenditures, $1.0 billion (97.5% CI: $0.3–2.7 billion) in prescription drug expenditures, and $0.2 billion (97.5% CI: $94 million–1.1 billion) in emergency room expenditures were associated with obesity. In aggregate, the annual direct medical expenditures that were associated with elevated BMI in childhood amount to $2.9 billion ($1.2–6.7 billion).”

In Table 2, the third subtable should appear as follows:

 Aggregate increase associated with overweight in both years, or obese in one year and overweight in the other (97.5% CI)aAggregate increase associated with or obese BMI in both years (97.5% CI)a
All children  
 Presciption drug expenditures$0.4 billion ($62 million–$1.6 billion)$0.7 billion ($0.2–1.1 billion)
 Outpatient visit expenditures$0.5 billion ($0.2–1.0 billion)$1.1 billion ($0.7–2.0 billion)
 Emergency room expenditures$150 million ($78–870 million)$73 million ($16–187 million)

On page 4, in the last line of the first column, “56.6 million” should be “11.6 million” and “41.0–92.6” should be “8.4–19.0.” In the first line of the second column, “43.6” should be “9.0.” In the second line of the second column, “19.3–73.0” should be “4.0–15.0.” In the last sentence of the paragraph, “1.79 million” should be “366,000” and “470,000–2.22 million” should be “96,000–455,000.”

In Table 3, the third subtable should appear as follows:

 Aggregate increase associated with overweight in both years, or obese in one year and overweight in the other (97.5% CI)aAggregate increase associated with or obese BMI in both years (97.5% CI)a
All children  
 Outpatient visitsNA (P > 0.05)11.6 million (8.4–19.0 million)
 Drug prescriptionsNA (P > 0.05)9.0 million (4.0–15.0 million)
 Emergency room visits188,000 (62,000–237,000)178,000 (34,000–218,000)

On page 5, in line 9 of the first paragraph of the first column, “$14.1 billion” should be “$2.9 billion.”
