研究背景：短期体能测试组合（SPPB）是一种常用的体能测试工具。它包括定时4米步行，定时重复椅子坐立测试，和10秒平衡测试（并排，半串联和全串联）。我们的目的是为40岁或40岁以上的社区居住挪威成年人建立以下方面的参考值：（1）总分;（2）三个分测验得分;（3）完成重复椅子坐立测试的时间和步行速度。此外，我们还探讨了SPPB的地板和天花板效应。研究人群包括40岁或以上的家庭居民，他们参加了特罗姆瑟研究的第7波。抽样调查了7 474名参与者（53.2%为妇女）完成了SPPB。根据性别和年龄组评价粗平均值和标准差（SD）。然后使用线性回归估计特定年龄的平均值，沿着并提供相应的95%置信区间。此外，使用分位数回归估计年龄特异性分位数（第5、10、25、50、75、90和95分位数）。结果观察到SPPB评分存在相当大的变异性。整个样本的平均SPPB总分为11.4（SD 1.3）分。平均而言，男性的SPPB总分比女性高0.28分（p < 0.001）。在所有5个年龄组（40-49岁、50-59岁、60-69岁、70-74岁、75-79岁和80岁以上）中均观察到显著的性别差异。身体机能的主要衰退发生在60年代中期，女性的衰退略早于男性。在所有年龄组中均观察到上限效应。结论本研究提供了全面的，最新的规范值SPPB措施，在社区居住的挪威人年龄至少40岁，可用于解释的研究结果，评估和建立适当的治疗目标。由于天花板效应，SPPB在评估40岁以上社区居住成年人的全方位身体功能方面具有重要的局限性。此外，我们的结论是，性能上的SPPB应报告的总和得分和注册的时间来完成重复椅子坐到站测试和定时4米步行测试。
Background The Short Physical Performance Battery (SPPB) is a common well-established instrument to measure physical performance. It involves a timed 4-m walk, timed repeated chair sit-to-stand test, and 10-s balance tests (side-by-side, semi-tandem, and full-tandem). We aimed to establish reference values for community-dwelling Norwegian adults aged 40 years or older in terms of (1) the total score; (2) the three subtest scores; and (3) the time to complete the repeated chair sit-to-stand test and the walking speed. Additionally, we explored floor and ceiling effects for the SPPB. Methods The study population comprised home dwellers aged 40 years or more who participated in the 7th wave of the Tromso study. A sample of 7474 participants (53.2% women) completed the SPPB. Crude mean values and standard deviations (SD) were evaluated according to sex and age group. Mean values at specific ages were then estimated using linear regression, along with corresponding 95% confidence intervals. Additionally, quantile regression was used to estimate age-specific percentiles (5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles). Results Considerable variability in SPPB scores was observed. The mean SPPB total score of the entire sample was 11.4 (SD 1.3) points. On average, the SPPB total score was 0.28 points greater in men than in women (p < 0.001). Significant sex differences were observed in all five age groups (40-49, 50-59, 60-69, 70-74, 75-79, and 80+ years). The main decline in the physical function occurred in the mid-sixties, with a slightly earlier decline in women than in men. Ceiling effects were observed in all age groups. Conclusions The present study provides comprehensive, up-to-date normative values for SPPB measures in community-dwelling Norwegians aged at least 40 years that may be used to interpret the results of studies evaluating and establishing appropriate treatment goals. Because of ceiling effects, the SPPB has important limitations for the assessment of physical functioning across the full spectrum of the community-dwelling adults aged 40+ years. Furthermore, we conclude that performance on the SPPB should be reported in terms of the total sum score and registered time to complete the repeated chair sit-to stand test and timed 4-m walk test.
