Models adjusted for: Parent and child age, sex, and weight status, race, and household income

Interpretation Example: Parent and child physical activity was classified as sedentary, light, moderate, and vigorous physical activity as measured by accelerometer over a minimum of four days. The relationship between parent time spent in the four physical activity categories (i.e., sedentary, light, and moderate plus vigorous physical activity) and child activity in each of the categories was examined. Parent time spent in sedentary and light physical activity was positively associated with child time spent in the same activity category (p<0.05). For example, a one-hour increase in parent sedentary activity was associated with 0.37 more hours of child sedentary activity (95% CI: 0.20, 0.54; P<0.001). Parent time spent in moderate-vigorous physical activity (MVPA) was positively associated with child MVPA, but the relationship was not statistically significant or substantively meaningful (P=0.13).
