The Impact of Grandchild Care on Physical Activity and Sedentary Behavior in People Aged 50 Years and Over

An observational follow-up study will be implemented over a period of 2 years, consisting of 3 test occasions with a fixed time interval of 1 year in between (T0 = baseline, T1 = 12 months, T2 = 24 months). Data will be collected in participants who provide grandchild care in a non-residential grandparent context as well as in a sample of non-caregiving grandparents and a sample of middle-aged and older adults not being a grandparent. All three samples will thus be prospectively monitored over a period of 2 years.
