Notes: Regression models included girlsโ race/ethnicity and age. Significant findings are emboldened. For associations where the overall statistic was significant (), post hoc comparisons of outcome-specific adjusted means were conducted. Adjusted means with different superscript letters are statistically significantly different using Tukey-Kramer adjusted value < 0.05. For example, girls who reported high levels of hanging around reported significantly less total physical activity compared to girls who did not report hanging around or reported low levels of hanging around.
