ATI, activity tracking intervention; NH, non-Hispanic; BMI, body mass index; OSA, obstructive sleep apnea; GERD, gastroesophageal reflux disease continuous variables are tested with independent t-test. Categorical variables are tested with chi-square test. Fisher’s exact test () was used when 25% of cells had less than 5 expected counts.
