How are combinations of physical activity, sedentary behaviour and sleep related to cognitive function in older adults? A systematic review
The relationships between cognitive function and each of physical activity, sleep and sedentary behaviour in older adults are well documented. However, these three time use behaviours are co-dependent parts of the 24-hour day (spending time in one leaves less time for the others), and their best balance for cognitive function in older adults is still largely unknown. This systematic review summarises the existing evidence on the associations between combinations of two or more time-use behaviours and cognitive function in older adults. Embase, Pubmed, PsycInfo, Medline and Emcare databases were searched in March 2020 and updated in May 2021, returning a total of 25,289 papers for screening. A total of 23 studies were included in the synthesis, spanning >23,000 participants (mean age 71 years). Findings support previous evidence that spending more time in physical activity and limiting sedentary behaviour is broadly associated with better cognitive outcomes in older adults. Higher proportions of moderate-vigorous physical activity in the day were most frequently associated with better cognitive function. Some evidence suggests that certain types of sedentary behaviour may be positively associated with cognitive function, such as reading or computer use. Sleep duration appears to share an inverted U-shaped relationship with cognition, as too much or too little sleep is negatively associated with cognitive function. This review highlights considerable heterogeneity in methodological and statistical approaches, and encourages a more standardised, transparent approach to capturing important daily behaviours in older adults. Investigating all three time-use behaviours together against cognitive function using suitable statistical methodology is strongly recommended to further our understanding of optimal 24-hour time-use for brain function in aging.
期刊介绍:
Experimental Gerontology is a multidisciplinary journal for the publication of work from all areas of biogerontology, with an emphasis on studies focused at the systems level of investigation, such as whole organisms (e.g. invertebrate genetic models), immune, endocrine and cellular systems, as well as whole population studies (e.g. epidemiology).
The journal also publishes studies into the behavioural and cognitive consequences of aging, where a clear biological causal link is implicated. Studies aimed at bridging the gap between basic and clinical aspects of gerontology, such as papers on the basic aspects of age-related diseases, are welcomed, as is research orientated toward the modulation of the aging process. Original research manuscripts, special issues, short reports, reviews, mini-reviews, and correspondence are published. Manuscripts on social aspects of aging and reports on clinical studies do not fall within the scope of the journal.
