Dataset of Intensity-specific and Posture-specific behaviour and health outcomes.

This dataset was used for the study with the aims to explore the compositional associations between intensity-specific and posture-specific behaviours and health outcomes in younger (M = 67.35 ± 2.03 years) and older (M = 75.73 ± 4.17 years) older adults. The study involved 309 older adults aged 65 and above from Czech Republic. Participants' intensity-specific behaviors, including sleep, SB, LPA and MVPA, and posture-specific behaviors, including lying, sitting, standing, moving, and walking, were measured using accelerometers. The data were analysed using compositional data analysis (CoDA). This dataset also include results of Timed up and Go test, Falls Efficacy Scale – International questionnaire, Short physical performance battery, usual gait speed and 5 times sit-to-stand test.

本数据集用于一项旨在探究不同强度特异性行为、姿势特异性行为与健康结局之间组成关联的研究，研究对象分为较年轻老年群体（平均年龄67.35±2.03岁）与高龄老年群体（平均年龄75.73±4.17岁）。本研究共纳入来自捷克共和国的309名65岁及以上老年受试者。受试者的强度特异性行为包括睡眠、静坐行为（Sedentary Behavior，SB）、低强度身体活动（Light Physical Activity，LPA）与中高强度身体活动（Moderate-to-Vigorous Physical Activity，MVPA），姿势特异性行为包括躺卧、坐姿、站姿、活动与行走，上述行为均通过加速度计（accelerometers）进行采集。数据采用组成数据分析（Compositional Data Analysis，CoDA）进行分析。本数据集同时包含计时起身行走试验（Timed Up and Go test）、国际跌倒效能量表（Falls Efficacy Scale – International questionnaire）、简易体能状况量表（Short Physical Performance Battery）、常规步速测试以及5次坐立试验（5 times sit-to-stand test）的相关结果。
