Sleep Quality of Physiotherapy Students Quality of Life and Physical Activity Level

The sleep quality was evaluated through the Turkish version of the PSQI containing 19 self-rated questions searching the sleep quality during the previous month. It has seven components as subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, use of sleep medications, and daytime dysfunction.

Each component is scored from 0 to 3, and the Global Pittsburgh Quality of Sleep (PQS) score is the sum of the scores of the seven components that is between 0 and 21. The higher Global PQS scores indicate poor sleep quality and the cut off score for poor sleep is 5 and over.

The physical activity of the participants was assessed through the Turkish version of the International Physical Activity Questionnaire -Short Form (IPAQ-SF), which includes 6 questions searching the frequency (days per week) and duration (hours) of walking, as well as low, moderate and vigorous physical activity that they engaged in during the last seven days prior to survey. Vigorous physical activity, defined by the questionnaire, referred to intense exercise that resulted in very rapid breathing and an elevated heart rate (e.g. intense weight lifting, aerobics, running, and cycling). Moderate physical activity was defined as less intense exercise that slightly heightened breathing and heart rate (e.g. less exertive cycling, fast walking, and light weight lifting).

The Turkish version of SF-36 was used to understand the health related quality-of -life (HRQOL) of the participants over the past four weeks in eight health concepts: limitations in physical activities because of health problems; limitations in social activities because of physical or emotional problems; limitations in usual role activities because of physical health problems; bodily pain; general mental health (psychological distress and well-being); limitations in usual role activities because of emotional problems; vitality (energy and fatigue); and general health perceptions. Additionally, the psychometric evaluation of the SF-36 generated two summary scores as the Mental Health Component Score and the Physical Health Component Score that the higher scores indicate better HRQOL.
