Validity of Low Physical Activity Questionnaire (LoPAQ)

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.

About this study

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.

Treatment and study plan

Primary outcomes

  1. Content validity of the Low Physical Activity questionnaire

    Time frame: Through out study completion, an average of 1 weeks

    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.

  2. Physical Activity Level

    Time frame: Through out study completion, an average of 1 weeks

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

  3. Physical Activity Level

    Time frame: Through out study completion, an average of 1 weeks

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

  4. Test-retest reliability of Low Physical Activity Questionnaire (LoPAQ)

    Time frame: Through out study completion, an average of 2 weeks

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

Secondary outcomes

  1. Self-reported physical function level

    Time frame: Through out study completion, an average of 1 weeks

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

  2. Physical performance

    Time frame: Through out study completion, an average of 1 weeks

    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.
