Brief Summary

Increased longevity is one of the greatest success stories in public health. However, ageing is accompanied by cognitive decline which affects people's daily functioning and, if it develops to dementia, their ability to live independently. By 2050, the number of people who develop dementia will triple to 152 million. The aim of this project is to precisely examine how physical activity (PA) and sleep, both modifiable lifestyle factors, are related to cognitive function and which role they can play in optimal cognitive ageing. To do so, a longitudinal study will be conducted, with objective measures of PA, sleep and cognition in midlife and older adults. This project will meet the current need for longitudinal studies with objective PA and sleep data, as well as provide, for the first time, in-depth information on associations of type of PA (aerobic vs muscle strengthening), characteristics of sleep (quality vs quantity) with specific cognitive domains (executive function and memory). Furthermore, although PA and sleep are related, the behavioural dynamics of combinations of PA and sleep on cognition has never been studied before. To fill this gap, these relationships will be examined with an innovative statistical approach, looking at data across a 24-hour period. The resulting deeper understanding of the precise relationship between PA, sleep and cognitive function will contribute to the development of preventive interventions for maintaining cognitive health at older age.

  • Physical activity & Sedentary behaviour (baseline) - objective: accelerometery 1

    ActiGraph's wGT3X-BT Activity Monitor (ActiGraph, Pensacola, FL) will be used. It measures time spent in different intensities of physical activity as well as sedentary behaviour and sleep. Participants will be asked to wear the accelerometer continuously during seven consecutive days, day and night, at their non-dominant wrist. In addition to wearing the accelerometer, participants will be asked to fill in a daily succinct diary with: (1) bed times, nap times; (2) non-wear times during the day; and (3) specification of most seated activity. These data will be used to complete and to explain gaps in the data set later on in the software programme. The following PA outcomes will be extracted from the ActiGraph data: average time spent per day in sedentary behaviour, light PA and moderate to vigorous PA.

  • Physical activity & Sedentary behaviour (baseline) - objective: accelerometery 2

    A second accelerometer will be placed on the right thigh, namely the activPAL (PAL Technologies Ltd, Glasgow, UK). This device measures postures due to its static acceleration and inclination features. It can quantify postural allocation - which is not possible with the ActiGraph - and is completely waterproof. The following additional PA outcomes will be extracted: time spent sitting/lying, standing, and walking.
