Errors in Units of Measure and Data: In the Original Contribution entitled “Maintaining a High Physical Activity Level Over 20 Years and Weight Gain,” published in the December 15, 2010, issue of JAMA (2010;304[23]:2603-2610), the unit of measure in the Results section of the Abstract should have been “Men maintaining high activity gained 2.6 fewer kilograms (+0.15 BMI units per year; 95% confidence interval [CI], 0.11-0.18 vs +0.20 in the lower activity group; 95% CI, 0.17-0.23), and women maintaining higher activity gained 6.1 fewer kilograms (+0.17 BMI units per year; 95% CI, 0.12-0.21 vs +0.30 in the lower activity group; 95% CI, 0.25-0.34). Men maintaining high activity gained 3.1 fewer centimeters in waist circumference (+0.52 cm per year; 95% CI, 0.43-0.61 cm vs 0.67 cm in the lower activity group; 95% CI, 0.60-0.75 cm) and women maintaining higher activity gained 3.8 fewer centimeters (+0.49 cm per year; 95% CI, 0.39-0.58 cm vs 0.67 cm in the lower activity group; 95% CI, 0.60-0.75 cm).” In the first paragraph of the section Longitudinal Analysis: Relationship of Habitual Activity Level With Changes in BMI, Waist Circumference, and Weight, data and the unit of measure should have been: “Average annual changes in BMI corresponded with the following cumulative weight changes over 20 years: men maintaining high activity gained 2.6 fewer kilograms (BMI increased in the high-activity group by 0.15 [95% CI, 0.11-0.18] per year vs a BMI increase of 0.20 per year in the low-activity group [95% CI, 0.17-0.23]) and women maintaining high activity gained 6.1 fewer kilograms (BMI increased in the high-activity group by 0.17 [95% CI, 0.12-0.21] per year vs a BMI increase of 0.30 per year in the low-activity group [95% CI, 0.25-0.34]). Men maintaining high activity gained 3.1 fewer centimeters in waist circumference (high-activity group gained 0.52 cm per year [95% CI, 0.43-0.61 cm] vs 0.67 cm per year in the low-activity group [95% CI, 0.60-0.75 cm]) and women maintaining high activity gained 3.8 fewer centimeters (high-activity group gained 0.50 cm [95% CI, 0.40-0.60 cm] vs 0.68 cm per year in the low-activity group [95% CI, 0.60-0.76 cm]).” This article has been corrected online.
