Dataset Posture specific behaviour and BMI

This dataset was used for the study with the aims to explore the compositional associations between posture-specific behaviours and obesity risk in younger (M = 67.35 ± 2.03 years) and older (M = 75.73 ± 4.17 years) seniors and investigate the differences in BMI associated with replacing time spent in lying, sitting and standing with moving or walking.<b> </b>The study involved 309 older adults aged 65 and above from Czech Republic. Participants' movement behaviours, including lying, sitting, standing, moving, and walking, were measured using accelerometers. The data were analysed using compositional data analysis (CoDA) and isotemporal substitution models to assess the impact of reallocating time between different activities on body mass index (BMI).
