Error in Text. In the article titled “Schoolwide Food Practices Are Associated With Body Mass Index in Middle School Students,” by Kubik et al published in the December 2005 issue of the ARCHIVES (2005;159:1111-1114) the estimated regression coefficient in the model was incorrectly interpreted as representing a 10% increase in body mass index (BMI) for every additional food practice permitted in a school. As described in the article, the dependent variable in the model was specified as BMI, calculated as weight in kilograms divided by the square of height in meters. Therefore, the estimated regression coefficient of β=0.10 would be correctly interpreted as a 0.10 BMI unit increase for every additional food practice a school permitted. In the abstract on page 1111, right-hand column, “Results” section, the third sentence should have read as follows: “Body mass index (BMI) of the students increased a 0.10 BMI unit for every additional food practice permitted in their school (P<.03).” On page 1113, left-hand column, “Results” section, paragraph 2, the last sentence should have read as follows: “Results indicated that for every additional food practice allowed by a school, student BMI increased by a 0.10 BMI unit (P<.03).” Also on page 1113, bottom left-hand column and upper right-hand column, “Comment” section, first paragraph, the fifth sentence should have read as follows: “However, the most important study finding was the positive association between these school food practices and student BMI, with BMI increasing a 0.10 BMI unit for every additional food practice allowed.”
