Finding effective ways to support people aged > 50 years to develop adequate levels of physical activity and sedentary behavior is necessary as these behaviors are positively related to the maintenance of functional independence and health-related quality of life. Given the widespread provision of grandparental child care, examining its impact on grandparents' energy-expenditure related behavior in the broader context of health is imperative. Therefore, the Healthy Grandparenting Project will aim to investigate the levels of physical activity and sedentary behavior, body composition and health-related quality of life in grandparents caring for their grandchildren and to compare these outcomes with non-caregiving grandparents and older adults without grandchildren, both momentarily and over time. An additional purpose is to identify possible predictors of potential changes over time.
A prospective cohort study will run over a period of 2 years, including three test occasions with a one-year time interval in between (T0 = baseline, T1 = 12 months, T2 = 24 months). A total of 276 participants will be recruited in Flanders through non-probability quota sampling (50-50% men-women), of which 92 caregiving grandparents, 92 non-caregiving grandparents and 92 non-grandparents. All three subsamples will be matched for age and sex. At each test occasion, anthropometric and body composition measurements will be determined. Participants' levels of physical activity and sedentary behavior will be assessed both objectively and subjectively by means of accelerometry and self-report questionnaires. Information about their grandchildren and the provided grandparental care (if applicable) as well as their health-related quality of life will also be assessed using self-report questionnaires. Mixed modelling will be used to identify differences in physical activity, sedentary behavior, body composition and health-related quality of life between the subsamples at baseline, as well as to evaluate and compare changes in energy-expenditure related behavior over time between subsamples and to identify predictors of the detected changes.
The Healthy Grandparenting Project is an innovative study examining the levels of physical activity and sedentary behavior in caregiving grandparents, non-caregiving grandparents and non-grandparents. Obtained results will help in the development of campaigns to maintain/improve health in adults at a more advanced age.

寻找有效的方法来支持 50 岁以上人群达到足够的身体活动和久坐行为水平是必要的，因为这些行为与保持功能独立性和健康相关的生活质量呈正相关。鉴于祖辈普遍提供育儿服务，因此必须在更广泛的健康背景下考察其对祖辈能量消耗相关行为的影响。因此，“健康祖辈育儿计划”将旨在调查照顾孙辈的祖辈的身体活动和久坐行为、身体成分和健康相关生活质量的水平，并将这些结果与非照顾祖辈和没有孙辈的老年人进行比较，包括即时和随时间的比较。另一个目的是确定可能的预测因素，以了解随时间变化的潜在变化。
一项前瞻性队列研究将持续 2 年，包括三个测试时间点，间隔 1 年（T0=基线，T1=12 个月，T2=24 个月）。通过非概率配额抽样（男女各 50-50%）在佛兰德招募 276 名参与者，其中 92 名照顾祖辈、92 名非照顾祖辈和 92 名非祖辈。所有三个子样本都将按年龄和性别匹配。在每个测试时间点，将确定人体测量和身体成分测量。通过加速度计和自我报告问卷客观和主观地评估参与者的身体活动和久坐行为水平。还将通过自我报告问卷评估有关他们孙辈和提供的祖辈照顾（如果适用）以及他们健康相关生活质量的信息。混合建模将用于确定基线时子样本之间身体活动、久坐行为、身体成分和健康相关生活质量的差异，评估和比较子样本之间随时间变化的能量消耗相关行为的变化，并确定检测到的变化的预测因素。
“健康祖辈育儿计划”是一项创新性研究，旨在调查照顾孙辈的祖辈、非照顾祖辈和非祖辈的身体活动和久坐行为水平。获得的结果将有助于制定保持/改善年龄较大成年人健康的宣传活动。
