Abstract

Introduction: Understanding daily movement patterns (i.e., the relative proportion of time spent on Sedentary behaviour (SB), light physical activity (LPA), moderate-vigorous physical activity (MVPA) and sleep) to establish links with chronic diseases is a contemporary topic. Little research has looked at the effects of 24-hour movement behaviour on bone health (particularly bone mineral density (BMD)) despite investigation on other health parameters.
The aim of this rapid narrative review was to build on previous work published on the association between SB and BMD in older adults by investigating the association of the more holistic 24- hour movement behaviours in relation to BMD.
Methods: A database search of Web of Science and NIH PubMed was conducted using broad MeSH terms (older adults, sedentary, and bone). Searches were limited from the year 2019 onward.
Results/Discussion: Five published articles were reviewed, and there are discrepancies amongst the findings which could be attributed to the different measurement methods (Peripheral Quantitative Computed Tomography (pQCT) versus Dual-energy X-Ray Absorptiometry (DEXA)) and the sites of measured BMD. There are also notable differences between genders, with BMD in men appearing to be most reliant on time spent in MVPA, compared to women who appear to see benefit to BMD with replacement of SB with LPA and not require more time spent in MVPA. This highlights the complexity of movement behaviours and requires further research.
