Using standing-based desks, as opposed to traditional sit-down desks, in classrooms for two consecutive years resulted in a significant decrease in BMI percentile, according to data published in the American Journal of Public Health.

Researchers recorded the height and weight of 380 students in 24 classrooms across three elementary schools in Texas. After adjusting for grade, race/ethnicity and gender, there was a statistically significantly decrease in BMI percentile among students who used standing desks for two consecutive years, with mean BMI increasing by 0.1 kg per meter squared for the treatment group and 0.4 kg per meter squared in the control group.
