This study aimed to examine within-subject differences in levels of physical activity (PA) and sedentary behavior (SB) among Flemish grandparents aged 50 years and older during a day of providing versus not providing grandchild care. Additionally, grandparents' PA and SB levels of the specific caregiving moment within the included care day were also compared with those of the corresponding specific time frame on the matching non-care day.
Data were obtained and pooled from three assessment time points of the Healthy Grandparenting Project. Objectively measured PA and SB levels were assessed through ActiGraphs wGT3x(+) worn during waking hours for seven consecutive days and expressed relative to the total wear time of the selected days or moments (i.e., percentage of time per day or per moment). Generalized linear mixed models were used to evaluate the within-subject differences in grandparents' light intensity PA (LIPA), moderate-to-vigorous intensity PA (MVPA) and SB levels between a care and non-care day as well as between the care and non-care moment of those respective days.
A total of 92 grandparents (64.6 ± 4.8 years, 67.4% women) were included in the analyses. During the care day and care moment, grandparents showed higher relative levels of LIPA (∆=4.0% and ∆=7.9%, respectively) and lower relative levels of SB (∆=3.7% and ∆=6.7%, respectively) as compared to their respective non-care day and non-care moment (all p < 0.001). While there was no significant difference in relative MVPA levels between a day of providing versus not providing grandchild care (∆=0.3%, p = 0.500), the grandparents showed significantly lower relative levels of MVPA during the specific care moment against the non-care moment (∆=1.3%, p = 0.029).
The higher percentage of time of LIPA and lower percentage of time spent on SB during a care day and care moment compared to a non-care day and non-care moment, highlight the positive impact of grandchild care provision on grandparents' activity levels, potentially improving other health-related outcomes. Furthermore, grandparents seem to compensate for their lower MVPA levels during the actual care moment since no differences in MVPA levels were found at day level when compared to a day without grandchild care.

本研究旨在探讨50岁及以上弗拉芒祖父母在提供和不提供孙辈照料的一天中,身体活动(PA)和久坐行为(SB)水平的个体内差异。此外,还将纳入的照料日中特定照料时刻的祖父母PA和SB水平与匹配的非照料日相应特定时间段的水平进行了比较。
数据来自健康祖父母项目的三个评估时间点并进行汇总。通过连续七天在清醒时间佩戴的ActiGraphs wGT3x(+)客观测量PA和SB水平,并相对于所选日期或时刻的总佩戴时间表示(即每天或每时的时间百分比)。使用广义线性混合模型评估祖父母在照料日和非照料日之间以及这些日子的照料时刻和非照料时刻之间的轻度强度PA(LIPA)、中度至剧烈强度PA(MVPA)和SB水平的个体内差异。
共有92名祖父母(64.6±4.8岁,67.4%为女性)纳入分析。与各自的非照料日和非照料时刻相比,在照料日和照料时刻,祖父母的LIPA相对水平较高(分别为Δ=4.0%和Δ=7.9%),SB相对水平较低(分别为Δ=3.7%和Δ=6.7%)(所有p<0.001)。虽然提供和不提供孙辈照料的一天之间MVPA相对水平没有显著差异(Δ=0.3%,p=0.500),但与非照料时刻相比,祖父母在特定照料时刻的MVPA相对水平显著较低(Δ=1.3%,p=0.029)。
与非照料日和非照料时刻相比,照料日和照料时刻LIPA时间百分比更高,SB时间百分比更低,这突出了提供孙辈照料对祖父母活动水平的积极影响,可能改善其他与健康相关的结果。此外,祖父母似乎在实际照料时刻弥补了较低的MVPA水平,因为与没有孙辈照料的一天相比,在日水平上未发现MVPA水平有差异。
