The purpose of this study was to investigate the relationship between meeting step count recommendations during the weekday and weekend and the weight status in school-aged children. A convenience sample of 855 fourth and fifth grade students (9.7 ± 1.0 years) was recruited from 4 elementary schools located in the Western United States. Body Mass Index (BMI) was calculated using standard procedures and then stratified to weight status categories (healthy weight, overweight/obese) using age- and sex-specific percentiles. Step counts were monitored for seven consecutive days using NL-1000 piezoelectric pedometers. A multilevel generalized linear mixed effect model was used to estimate the odds ratios of meeting segmented step counts recommendations and weight status. Students meeting weekday step count recommendations associated with 39% lower odds of overweight/obesity compared to those not meeting any recommendations (P = 0.02). Those meeting both weekday and weekend recommendations associated with 67% lower odds of overweight/obesity compared to children not meeting any recommendations (P = 0.01). Meeting weekend step count recommendations did not associate with weight status. This study supports the positive relationship between segmented step counts and the healthy weight status of school-aged children.
