目标：青春期通常与体力活动（PA）下降和昼夜节律向晚上转变有关，但尚不清楚这些转变是否相互交织。我们纵向和横向探讨了早睡型的时间型和遗传倾向如何与PA相关，如自我报告和青春期早期和晚期的体动记录仪测量。方法：我们的样本来自1998年出生的芬兰社区队列，该队列提供了基于活动记录仪的PA信息，并根据12岁时的睡眠中点客观测量了睡眠-觉醒节律（N = 353，女孩= 187）和17（N = 171，女孩= 98）。自我报告的昼夜节律偏好和主观PA的信息在17岁时可用。根据最近的全基因组关联研究（GWAS）结果，通过计算多基因评分（PGS）来评估多个单核苷酸多态性对晨性的遗传效应。结果：从12岁到17岁，男孩的PA下降了40%（p <0.0001），女孩下降了32%（p < 0.0001）。晚些时候的睡眠中点与一般、轻度和中度至剧烈PA水平的降低仅在12岁时显著相关（所有p < 0.05），但在17岁时不相关（所有p >= 0.36）。然而，那些在17岁时具有更倾向于晚上的昼夜节律偏好的人有更多的久坐行为（p < 0.01）和较低水平的一般（p = 0.01）、轻度（p < 0.01）和中度至剧烈的PA（p < 0.05）。他们也有较差的主观评价，他们的健身水平（p < 0.01），他们行使较少（所有p = 0.13）。结论：这项研究的结果强调了昼夜节律偏好的影响，在青少年的身体活动行为。自我评估的昼夜节律偏好与较低的PA和更大的下降，它在青春期的晚上。此外，PA显着下降，特别是在男孩从青春期早期到后期。鼓励体育活动的干预措施应专门针对晚上取向的青少年。(C)2020爱思唯尔B.

Objective: Adolescence is often associated with decline in physical activity (PA) and a circadian shift towards eveningness, but it is not known whether these transitions are intertwined. We explored longitudinally and in cross-section how chronotype and genetic liability for morningness associate with PA as self-reported and measured by actigraphy in early and late adolescence.Methods: Our sample comes from a longitudinal Finnish community-cohort born in 1998 with information on actigraph-based PA and objectively measured sleep-wake rhythm based on midpoint of sleep at ages 12 (N = 353, girls = 187) and 17 (N = 171, girls = 98). Information on self-reported circadian preference and subjective PA was available at age 17. The summarized genetic effects of multiple single nucleotide polymorphism for morningness was assessed by calculating polygenic score (PGS) based on the results on a recent genome-wide association study (GWAS).Results: PA declined by 40% (p < 0.0001) in boys and by 32% in girls (p < 0.0001) from age 12 to 17. Later midpoint of sleep correlated significantly with lower level of general, light and moderate to vigorous PA only at age 12 (all p < 0.05) but not at age 17 (all p >= 0.36). However, those with circadian preference more towards eveningness at age 17 had more sedentary behavior (p < 0.01) and a lower level of general (p = 0.01), light (p < 0.01) and moderate to vigorous PA (p < 0.05). They also had poorer subjective assessment of their fitness level (p < 0.01) and they exercised less (all p = 0.13).Conclusions: Findings of this study highlighted the influence of circadian preference on physical activity behavior in adolescence. Self-assessed circadian preference towards eveningness associated with lower PA and greater decline of it during adolescence. Furthermore, PA declined significantly especially among boys from early to late adolescence. Interventions encouraging physical activity should target specifically evening-oriented adolescents.
