To describe the agreement between parent- and adolescent- reports of adolescent moderate-to-vigorous intensity physical activity (MVPA) and to determine sociodemographic factors associated with MVPA reporting differences during the COVID-19 pandemic.
We analyzed data collected in May 2020 from the Adolescent Brain Cognitive Development Study (ABCD, N = 4841), a U.S. prospective cohort study. We quantified past weekly adolescent MVPA levels as reported by the parent and adolescent (referent). Intra-class correlation coefficients (ICC) and Bland-Altman plots were used to examine the degree of agreement between parent- and adolescent- reports.
When quantifying adolescent MVPA during the same recall period, median (p25, p75) MVPA (h∙wk.) was 2.17 (0.00, 6.00) as reported by adolescents and 1.52 (0.29, 4.75) by parents with a mean difference of 4.89. Statistically significant differences in reports of MVPA were found in households with income > $75,000: on average, adolescents reported higher MVPA levels than their parents. Bland-Altman plots illustrated that, among adolescents reporting no or little MVPA, there was higher parent-adolescent agreement. However, among adolescents reporting high levels of MVPA, there was less agreement between the parent- and adolescent- reports.
Despite more time spent together at home during the pandemic, there was generally low agreement between parent- and adolescent- reports of adolescent MVPA. Future research could examine parent-adolescent agreement of MVPA within the context of device-based measures (e.g., accelerometers), determine reasons for differences in parent-adolescent reporting of MVPA, and inform interventions for improved parental involvement and monitoring of MVPA.
描述青少年中父母和青少年报告的中度至剧烈强度身体活动（MVPA）之间的一致性，并确定与 COVID-19 大流行期间 MVPA 报告差异相关的社会人口因素。
我们分析了 2020 年 5 月从美国前瞻性队列研究青少年大脑认知发展研究（ABCD）中收集的数据（N=4841）。我们根据父母和青少年的报告（参考）来量化过去每周青少年的 MVPA 水平。使用组内相关系数（ICC）和 Bland-Altman 图来检验父母和青少年报告之间的一致性程度。
当在相同的回忆期内量化青少年的 MVPA 时，中位数（p25，p75）MVPA（h·wk.）由青少年报告为 2.17（0.00，6.00），由父母报告为 1.52（0.29，4.75），平均差异为 4.89。在收入>75,000 美元的家庭中，MVPA 的报告存在显著差异：平均而言，青少年报告的 MVPA 水平高于其父母。Bland-Altman 图表明，在报告无或少量 MVPA 的青少年中，父母与青少年之间的一致性较高。然而，在报告高水平 MVPA 的青少年中，父母和青少年之间的报告一致性较低。
尽管大流行期间在家中度过的时间更多，但父母和青少年对青少年 MVPA 的报告通常一致性较低。未来的研究可以在基于设备的措施（例如加速度计）的背景下检查 MVPA 的父母-青少年一致性，确定父母-青少年报告 MVPA 差异的原因，并为改善父母参与和监测 MVPA 的干预措施提供信息。
