简要总结
Given the widespread provision of grandparental child care, examining its impact on grandparents' energy-expenditure related behaviors in the broader context of health is imperative. The maintenance of functional independence and good quality of life is critical at a more advanced age. It has been put forward that an increased duration, frequency and intensity of physical activity (PA) combined with a restriction of sedentary behavior (SB) is the most important strategy to reduce morbidity risk and to foster health in an aging population. The present study aims to fill a gap in current knowledge on (changes in) caregiving grandparents' PA levels and SB patterns. An observational follow-up study will be conducted to examine and compare both energy-expenditure related behaviors linked to body composition and health-related quality of life among caregiving grandparents, non-caregiving grandparents and non-grandparent peers, both momentarily and over time. This fundamental research aims to provide scientific evidence contributing to the promotion of healthy grandparenting in people on the threshold of old age in modern society.
详细描述
The first objective of the study is to provide a detailed overview of habitual levels of physical activity and sedentary behavior among caregiving grandparents in relation to their body composition and health-related quality of life (including both physical and mental function), and to identify to what extent these outcome measures are associated with the number, sex and age of the grandchild(ren) as well as with the intensity of grandparents' provision of child care, while taking some demographic characteristics of the grandparent (i.e., age, sex, marital status, socio-economic status (SES)) into account.
The second objective is to compare caregiving grandparents' energy-expenditure related behaviors (i.e., physical activity and sedentary behavior) and their link with health-related measures of interest (i.e., body composition and quality of life) with both non-caregiving grandparents and non-grandparent peers as relevant control groups.
The third objective is to investigate (age-related) changes in physical activity and sedentary behavior linked to body composition and health-related quality of life among caregiving grandparents versus non-caregiving grandparents as well as non-grandparents both in the short and the longer term, and to identify possible predictors of these changes over time. Additionally, it is the intention to examine the impact of middle-aged and older adults making the transition to (caregiving) grandparenthood on both energy-expenditure related behaviors as well as the health-related measures of interest.

结局指标
主要结局
Change in sedentary behavior
时间窗: At baseline (T0), at 12 months (T1), at 24 months (T2)
Sedentary behavior will be assessed subjectively by using a self-reported questionnaire (Sedentary Behavior Questionnaire for (older) adults in Dutch) and objectively by using a tri-axial accelerometers (Actigraph, wGT3X-BT) over a one-week period.
Change in physical activity
时间窗: At baseline (T0), at 12 months (T1), at 24 months (T2)
Physical activity will be assessed subjectively by using a self-reported questionnaire (International Physical Activity Questionnaire (IPAQ - Dutch version)) and objectively by using a tri-axial accelerometers (Actigraph, wGT3X-BT) over a one-week period.
