In this the 87 dyads, older sister physical activity was significantly in the more youthful aunt productive times (B = 0.45;p = 0.004) and you may Fulfilled-minutes (B = 0.45;p = 0.003) in the summer but not slide; more mature sis inactive choices is actually notably with the young sis sitting (B = 0.23;p = 0.01) and you will display screen time moments (B = 0.23;p = 0.004) throughout the slide but not june.
