The Relationship Between Health Literacy, Physical Activity, Back Pain and Posture Habits in University Students

The Health Literacy Scale is comprised of 25 items, which are organised into four subscales. The scale comprises four subscales, namely access to information (items 1-5), understanding information (items 6-12), appraisal/evaluation (items 13-20) and application/use (items 21-25). The total score that can be obtained from the scale varies between 25 and 125 points. As the score obtained from the scale increases, the level of health literacy of the individual also increases.

It is a short form consisting of 7 questions covering the last week in the assessment of physical activity level. The calculation of the total score of the short form includes the sum of the duration (minutes) and frequency (days) of walking, moderate intensity activity and intensity activity. The sitting score is calculated separately. The survey includes questions about PA performed for at least 10 minutes in the last week. A score is obtained as "MET-minutes/week" by multiplying minutes, days and MET values.

The questionnaire was devised with the objective of evaluating the typical postural habits exhibited during the course of daily activities. The questionnaire comprises 31 questions. Four questions pertain to activities undertaken while standing, nine to activities performed while sitting, 13 to activities involving weight bearing, and five to activities carried out while lying down.
