Shedding light on light exposure in elderly with intellectual disabilities.

ABSTRACT:

Background

Light exposure affects mood and sleep regulation. Sleep problems and mood complaints are common in elderly with intellectual disabilities (ID) living in care facilities. Insufficient light exposure is hypothesised to contribute to the high prevalence of these problems. The current study is the first to describe the personal light exposure pattern during the waking day in elderly with ID.

Methods

The study sample consists of 82 elderly with ID (aged 62.3 ± 9.4 years) living in 16 residential homes of three care organisations in the Netherlands. Personal light exposure was measured continuously for 7-10 days using a HOBO data logger light sensor, measuring illuminance at chest height. Participants wore a wrist-worn accelerometer (Actiwatch or Geneactiv) to indicate the bedtimes to determine the waking day.

Results

The variation in illuminance is small during the waking day. Elderly with ID spend most of their waking day (mean duration = 14:32:43 h) in dim light (1-500 lux) environment and spend a median of 32 min in light > 1000 lux. Within participants, the threshold associated with better sleep (>50 min of light > 1000 lux) was reached for 34% of the days, and the threshold associated with less depressive symptoms (>30 min of light > 1000 lux) was reached in 46% of the days. Exposure > 1000 lux was lower during weekends than during weekdays.

Conclusion

Elderly with ID spend most of their waking day in low light levels and did not meet the proposed values associated with better sleep and mood. Given the importance of adequate light exposure for regulation of sleep and mood, and the prevalence of sleep and mood problems in elderly with ID, the current study suggests that the lit environment for this already frail population should be given more attention.

Project description:Background: Older adults with intellectual disability are exposed to a higher anticholinergic burden compared to general older adults. This is due to a higher rate of both mental and neurological disorders among people with intellectual disability. The use of medications with a high anticholinergic burden is associated with adverse effects including daytime dozing, constipation and higher dependence level in the Barthel index for measuring activities of daily living. This scoping review aims to map and examine the existing research on physical and cognitive adverse effects associated with the long-term impact of anticholinergics among people with intellectual disabilities. Methods: The search was conducted in: PubMed, Cochrane library, EMBASE, Medline, Science Direct, CINAHL Complete and PsycINFO. Preliminary studies, grey literature, and conference papers were searched in related electronic databases. The search terms included terms related to 'anticholinergic', 'long-term exposure', 'intellectual disability' and 'adverse drug reaction' with Boolean operator 'and'. Studies with at least three months' exposure to anticholinergics were included. The search was restricted to research papers on people with intellectual disability aged 40 or over and publication in the English language only. Initially, it was conducted in May and June 2021 and covered the publication period between 1970 and 2021. It was re-run in October 2021. Results: The conducted search provided 509 records of publications and grey literature. Duplicates were removed using EndNote 20 and resulted in 432 remaining records. Then, 426 further records were excluded because they were deemed irrelevant, or non-longitudinal studies or conducted on different populations. Only six full articles were retrieved to assess their eligibility and all were excluded due to different study populations. This resulted in no studies meeting the stated inclusion criteria. Conclusions: Further research is urgently required to examine the long-term adverse effects associated with higher anticholinergic scores among older people with intellectual disability.
