Abstract
Sleep becomes more fragmented with age. Between 20% and 43% of the elderly populations are affected. Good and poor sleepers underestimate their sleep length. There may be difficulty initiating and maintaining sleep: there may also be early morning awakening and daytime napping. Psychological and physical impairment and life-events may affect sleep. In order to aid older adult’s with their sleep disorders, general practitioners (GPs) require a knowledge of normal patterns of sleep in the older adult’s. (Gerad P. et al., 2018)
A sleep disorder is any medical disorder which negatively affects a person’s healthy sleep patterns. Usually this involves less than adequate sleep to the extent that this may interfere with the person’s normal physical, mental and emotional functioning, but excessive sleep, can also be a problem. There are at least 80 different sleep disorders that have been identified, the most common and well-known being insomnia. (Buysse DJ. et al., 2019)
This study aimed to assess the effect of sleep pattern on older adult’s life through:
1- Assessing knowledge of older adult’s about sleep pattern.
2- Assessing practice of older adult’s toward sleep disorders.
3- Assessing sleeping pattern of older adult’s.
4- Assessing Effect of sleep pattern on older adult’s life.
Research Questions
1- What are the levels of knowledge of older adult’s about sleep pattern?
2- What are the practices performed by older adult’s related to sleep pattern?
3- What are the effects of the sleep pattern on older adult’s life style?
4- Is there a relation between Socio -demographic characteristics of older adult’s and sleep pattern?
5- Is there a relation between older adult’s health problems and their sleep pattern?
Research design
A descriptive analytical design was used to conduct this study and answer the research question.
Study Setting
The study was conducted at the outpatient clinic of Al Shaheed Ahmed Shawky Hospital of older adults in Eldemerdash Hospital affliatted to Ain Shams University Hospitals in Cairo, which considered the Basic Hospital in East Cairo. Serve a large number of older adult’s and provide health care for in all elderly of population in Egypt.

Tools of Data collection:
Tow tools were used to achieve the aim of this study:
First tool: A Structured Interviewing Sheet: it was designed by the investigator and written in simple Arabic language based on scientific Literature review to gather data in relation to the following parts:

There was a highly statistical significant relation between older adult’s total knowledge and their total reported practice (p. value <0.001). There was a statistical significant relation between older adult’s total reported practice and their total older adult’s health problems (p. value <0.05).
