• Conditions: Healthy Young Adult
• Interventions: Other: Evaluation of sleep quality, sleep duration, heart rate and step count

• Registration Number: NCT05829525
• Lead Sponsor: Tokat Gaziosmanpasa University

Brief Summary

This study aims to evaluate the relationship among sleep duration, heart rate, number of steps, and sleep quality.

Detailed Description

There are studies examining the relationship between sleep quality and physical activity in young adults. In these studies, weakly significant relationships were recorded between sleep quality and physical activity level. However, in these studies, the level of physical activity was evaluated with the International Physical Activity Questionnaire and the questionnaire was filled in within the framework of certain activities. In this study, physical activity will be evaluated with the number of steps taken per day. In addition, there is no study examining the relationship between sleep quality, sleep duration, and heart rate in young adults. With the current study, parameters that will affect physical activity such as sleep duration, heart rate, and the number of steps will be evaluated and their relationship with sleep quality will be determined. Sleep quality will be assessed by the Pittsburgh Sleep Quality Index, sleep duration, heart rate, and step count will be assessed by the Fitbit® Inspire 2 (Fitbit, Inc., San Francisco, California, USA), and quality of life will be assessed by the Nottingham Health Profile. The results will be analyzed using the SPSS version 22.0 computer package program.

Healthy young adults group	Evaluation of sleep quality, sleep duration, heart rate and step count	Face-to-face assessment study

Primary Outcome Measures

Name	Time	Method
Sleep quality	1 day	The Pittsburgh Sleep Quality Index (PSQI) will be used to assess sleep quality. PSQI is a scale that provides information on sleep quality and the type and severity of sleep disturbance in the past week. Turkish validity and reliability were established. In the scale consisting of 24 questions in total, 19 questions are answered by the person, while the other 5 questions are filled by the person's bedmate. 7 sub-dimensions (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping pills, daytime dysfunction) are evaluated with 19 questions answered by the individual. Each item in the scale scores between 0 (no distress)-3 (severe distress). The sum of the scores of the seven subdimensions gives the total PSQI score (between 0-21). Those with a total score of 5≥ "good sleep", and those with a score of 5\< are considered "poor sleep quality".
Heart rate	1 day	Heart rate count will be evaluated with the Fitbit® Inspire 2 (Fitbit, Inc., San Francisco, California, USA). Individuals will wear a Fitbit® Inspire 2 (Fitbit, Inc., San Francisco, California, USA) on one wrist. During a day, individuals' heart rate will be recorded. They will be asked to continue with their normal routines, in abnormal cases the measurement will be repeated. Data will be transferred via Bluetooth to smartphones or tablets accessible via the Fitbit App. Individuals' privacy will be protected by downloading the Fitbit app only to the principal investigator's device and creating separate accounts, one for each Fitbit device, without providing personal information.
Sleep duration	Single assessment for 1 day	Sleep time will be evaluated with the Fitbit® Inspire 2 (Fitbit, Inc., San Francisco, California, USA). Individuals will wear a Fitbit® Inspire 2 (Fitbit, Inc., San Francisco, California, USA) on one wrist. During a day, individuals' sleep duration will be recorded. They will be asked to continue with their normal routines, in abnormal cases the measurement will be repeated. Data will be transferred via Bluetooth to smartphones or tablets accessible via the Fitbit App. Individuals' privacy will be protected by downloading the Fitbit app only to the principal investigator's device and creating separate accounts, one for each Fitbit device, without providing personal information.
Nottingham Health Profile	1 day	The Nottingham Health Profile (NHP) will be used to assess quality of life. The NHP is a general quality of life questionnaire that measures the perceived health problems and the extent to which these problems affect normal daily activities. The questionnaire consists of 38 items. Questions are answered as 'yes' or 'no'. The questionnaire assesses six parameters related to health status. These parameters are; pain (8 items), physical activity (8 items), energy (3 items), sleep (5 items), social isolation (5 items), emotional reactions (9 items). Each subparameter is scored between 0-100. 0 indicates best health, 100 indicates worst health. The total NHP score is derived from the sum of the subscores.
Step count	1 day	Step count will be evaluated with the Fitbit® Inspire 2 (Fitbit, Inc., San Francisco, California, USA). Individuals will wear a Fitbit® Inspire 2 (Fitbit, Inc., San Francisco, California, USA) on one wrist. During a day, individuals' step count will be recorded. They will be asked to continue with their normal routines, in abnormal cases the measurement will be repeated. Data will be transferred via Bluetooth to smartphones or tablets accessible via the Fitbit App. Individuals' privacy will be protected by downloading the Fitbit app only to the principal investigator's device and creating separate accounts, one for each Fitbit device, without providing personal information.
