Abstract Altered 24-hour rest-activity rhythms may be associated with cognitive impairment in older adults, but evidence from prospective studies is limited. Non-parametric methods were used to assess actigraphy-based activity patterns in 2,496 older men. Incident cognitive impairment was assessed four times over 12 years using the Modified Mini Mental State Examination (3MS) and Trails B tests, self-reported medication use, and clinical diagnosis. The highest quartile (vs. the lowest) of intradaily variability and the lowest quartiles (vs. the highest) of interdaily stability and relative amplitude were associated with incident cognitive impairment ((Hazard ratio (95% confidence interval): 1.82 (1.31, 2.53)), 1.36 (0.99, 1.86), and 1.85 (1.33, 2.56), respectively). A larger increase in intradaily variability over 7.5 years was associated with a greater subsequent decline in 3MS scores but not in Trails B performance. In conclusion, less stable and more variable rest-activity rhythms may represent early biomarkers of cognitive impairment in older men.

Rest Activity

Abstract Introduction Rest-activity patterns are important aspects of healthy sleep and may be disturbed in conditions like circadian rhythm disorders, insomnia, insufficient sleep syndrome, and neurological disorders. Long-term monitoring of rest-activity patterns is typically performed with diaries or actigraphy. Here, we propose a fully unobtrusive method to obtain rest-activity patterns using smartphone keyboard activity. This study investigated whether keyboard activities from habitual smartphone use are reliable estimates of rest and activity timing compared to daily self-reports within healthy participants. Methods First-year students (n = 51) used a custom smartphone keyboard to passively and objectively measure smartphone use behaviours, and filled out the Consensus Sleep Diary for one week. The time of the last keyboard activity before a nightly absence of keystrokes, and the time of the first keyboard activity following this period were used as markers. Results Results revealed high correlations between these markers and user-reported onset and offset of resting period (r ranged 0.74 - 0.80). Linear mixed models could estimate onset and offset of resting periods with reasonable accuracy (R2 ranged 0.60 - 0.66). This indicates that smartphone keyboard activity can be used to estimate rest-activity patterns. In addition, effects of chronotype and type of day were investigated. Conclusion Implementing this monitoring method in longitudinal studies would allow for long-term monitoring of (disturbances to) rest-activity patterns, without user burden or additional costly devices. It could be particularly useful in studies amongst clinical populations with sleep-related problems, or in populations for whom disturbances in rest-activity patterns are secondary complaints, such as neurological disorders.

ABSTRACTPrevious research on activity patterns of the elderly has relied on survey and interview methods which have depended on special measures and the long term memory of the respondents. This paper examines the use of time budgets in studying changing activity patterns across the life span. The independent variables of interest in this analysu were age, sex, marital status, education, and whether or not the individual lives alone. The dependent variable was the activity patterns of the individual. Results indicate that only age, of the factors considered here, endured significance across all comparisons.

When analyzing the historical and medical aspects of the organization of medical and social services for the elderly and senile people in Russia in the late XX — early XXI centuries not only obvious achievements in this sphere, but also a number of problems requiring solution were identified. The primary role in the delivery of medical care to geriatric patients is assigned to the primary health care sector. However the work of the geriatric service in the format of a single system for the provision of long-term medical and social care based on the continuity of patient management between differ- ent levels of the health care system and between the health and social protection services is not well organized. There is no clear coordination and interaction between health care and social protection institutions, functions of which include providing care to older citizens, and it significantly reduces the effectiveness of the provision of both medical and social services.
