Activity counts per 30-sec were uploaded to determine the amount of time spent sedentary, and in light, moderate, and vigorous intensity activity during the monitoring period based on the classifications of Freedson, Melanson, and Sirard ( 1998 ).

The minimum wear time to be included in the analysis was 4 days (3 weekdays and 1 weekend day) with a minimum 10 hours of data per day, after excluding nonwear time of 60 consecutive minutes with zero acceleration ( 5 ). Participants could wear the accelerometer for another

The purpose of this study was to examine the association between parent and adolescent levels of physical activity, sedentary behaviors, and sleep among a group of overweight and obese adolescents.
Baseline data of parent–adolescent pairs who enrolled in a lifestyle modification intervention were analyzed for this study (n = 176). Participants completed questionnaires about their screen time (TV, video game, and computer time), wore an accelerometer for 8 days, and completed a sleep diary for 1 week. In total, 98 parent–adolescent dyads provided valid data for the analyses. Multivariable regression analyses were conducted to assess the relationship between parent and adolescent’s moderate-to-vigorous activity (MVPA), step counts, sedentary behaviors, and sleep duration. Analyses were split by weekday, weekday evening and weekend.
Parent–adolescent MVPA was significantly associated on weekdays (b = 0.18; SE = 0.08; β = 0.26), weekday evenings (b = 0.21; SE = 0.08; β = 0.28), and weekends (b = 0.29; SE = 0.12; β = 0.27). This study found associations between parent–child video game time on weekends (b = 1.10; SE = 0.49; β = 0.24) and computer time on weekdays (b = 0.42; SE = 0.19; β = 0.23). Adolescent sleep was associated with parental sleep on weekdays only (b = 0.38; SE = 0.09; β = 0.46).
The findings warrant further investigation into the direction and mechanism of the relationship between parent and adolescent weight related behaviors.
