The goal of this observational study is to assess validity and reliability of Persian
Version of Low Physical Activity Questionnaire. The main questions it mains to answer
are:

What is the level of physical activity in hemodialysis patients? Is Persian Version of
Low Physical Activity Questionnaire, Valid to assess physical activity levels of dialysis
patients?

Is Persian Version of Low Physical Activity Questionnaire, reliable?

Participants will answer 3 questionnaires and will do some functional tests.

Chronic Kidney Diseases

End Stage Renal Disease

Hemodialysis Complication

Currently, between 8 and 16 percent of the world's population is suffering from chronic
kidney disease, and this number is increasing day by day, and it is predicted that by
2040, kidney disease will be the fifth cause of death.

End-stage kidney disease patients, especially hemodialysis patients, face various
problems, and during the years of dialysis, they suffer from many complications and
problems, such as repeated hospitalizations, reduced physical performance, reduced
aerobic capacity, low quality of life, and having a sedentary life. suffer, so that the
activity level of these patients is between 20 and 50% of healthy people.

The physical activity level of patients undergoing hemodialysis treatment is low and
significantly lower than the same inactive control groups. Research has shown that the
level of physical activity of hemodialysis patients gradually decreases by approximately
4.5% per month during the entire period of the disease . In addition, the activities
related to the work done at home constitute the largest part of the energy consumption of
hemodialysis patients, which means that the types of activities of hemodialysis patients
are usually limited to the lower category.

Valid instruments for measuring physical activity at the low end of the physical activity
range and producing quantitative results are required among dialysis patients who are
extremely inactive. This study aimed to translate and adapt a Persian version of the low
physical activity questionnaire (LoPAQ) and to examine its reliability and validity among
hemodialysis patients.

Validity and Reliability of Persian Version of Low Physical Activity Questionnaire (LoPAQ)

Content validity Content validity of the questionnaire was measured using the content
validity index (CVI). The item-level CVI will be calculated as the percentage of
specialists giving a rating of either 3 or 4. Generally, a CVI higher than 0.78 suggest
good content validity.

Physical activity level was assessed by Low Physical Activity Questionnaire (LoPAQ).

Physical activity level was assessed by Community Health Adults Model Program for Seniors
(CHAMPS) questionnaire.

Test-retest reliability of Low Physical Activity Questionnaire (LoPAQ) was determined by
calculating the intraclass correlation coefficient (ICC,two-way mixed analysis of
variance).

Self-reported physical function was assessed using the Physical Function scale of the
Quality of Life questionnaire

Physical performance was assessed using the Short Physical Performance Battery test. The
range of this test score is 0-12. Those who have disabilities in the activity of their
daily living will take lower scores.

They will fill 3 questionnaires and will do some functional tests.
