Self-Reported Moderate-to-Vigorous Physical Activity: Its Association with Health-Related Quality of Life in a Large Cohort of People with Chronic Diseases.

The aim of this study was to investigate the dose-response relationship between physical activity and health-related quality of life (HRQoL) in a large population-based sample of people with chronic disease. We analysed the data of 29,271 adults (15,315 women) who were diagnosed with chronic diseases and participated in the Welsh Health Survey (Wales, UK; data collection 2011-2015). Participants were classified, based on their weekly minutes of moderate-to-vigorous physical activity (MVPA), into four groups as follows: inactive (no MVPA), insufficiently active (<150 min/week), sufficiently active (≥150-<300), and very active (≥300). The main outcome was HRQoL measured via the Short-Form 36 Health Survey (SF-36). This study found a curvilinear association between MVPA and HRQoL and a dose-response relationship for the perception of general health and vitality domains. Compared to inactive participants, those who were very active had higher HRQoL scores (coefficient = 12.54; 95% confidence interval [CI] 11.39-13.70), followed by sufficiently active (coefficient = 11.70; 95% CI 10.91-12.49) and insufficiently active (coefficient = 9.83; 95% CI 9.15-10.51) participants. The fully adjusted regression model showed curvilinear associations between MVPA and the domains of SF-36. Future research should find ways to motivate people with chronic diseases to engage in physical activity. The evidence to support regular exercise in individuals with chronic diseases in all age groups is strong and compelling, and patients should be encouraged to regularly devote more time to physical activity in order to improve their health and well-being.

Impact of the 2019 Coronavirus Disease Pandemic on Health-Related Quality of Life and Psychological Status: The Role of Physical Activity.

This study investigated the impact of the 2019 coronavirus disease (COVID-19) pandemic on health-related quality of life (HRQoL) and psychological status among Saudi adults, and whether physical activity modifies this association. The participants were 518 adults aged ≥18 years (67.4% men). Using an online survey, data regarding demographic information, the impact of COVID-19 (assessed by the Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders-5), HRQoL (Short Form-8), psychological distress (Depression, Anxiety and Stress Scale), and physical activity behavior (International Physical Activity Questionnaire-Short Form) were collected. The results demonstrate that adults reporting moderate or high levels of impact of COVID-19 had a lower HRQoL and higher psychological distress than adults reporting a low impact. HRQoL was higher for adults reporting any level impact (low, moderate, or high) of COVID-19 when they participated in recommended levels of physical activity (≥600 metabolic equivalent (MET)-min/week of total physical activity). Psychological distress was lower for adults reporting a high level of impact when they participated in recommended physical activity. Moderate or high levels of impact of COVID-19 were associated with a significantly lower HRQoL and higher psychological distress than the low impact of COVID-19. However, these associations were moderated by the recommended levels of physical activity.

Non-specific chronic low back pain and physical activity: A comparison of postural control and hip muscle isometric strength: A cross-sectional study.

Most research on sedentary lifestyle has focused on pain and disability, while neuromuscular outcomes (postural control and strength) have received less attention. The objective of the study was to determine whether low level of physical activity is negatively associated with measures of lower body muscular strength and postural control in individuals with and without non-specific chronic low back pain (NSCLBP).Twenty-four subjects with NSCLBP (28.8 ±â€Š5.9 years) and 24 age, gender, and body mass index matched healthy controls participated in the study. Subjects were sub-classified into 4 subgroups based on their physical activity level: Non-active NSCLBP; Active NSCLBP; Non-active healthy control; and Active healthy control. Each subgroup consisted of 12 subjects. Peak force of hip muscles strength was assessed using a handheld dynamometer. Postural control was assessed using computerized posturography and the Y Balance Test.There was no significant group by physical activity interaction for strength and static and dynamic postural control, except for static control during left single leg stance with eyes closed (P = .029). However, there was a significant difference in strength and postural control by physical activity (P < .05). Postural control and peak force of hip muscles strength were significantly associated with physical activity (r ranged from 0.50 to 0.66, P < .001 and r ranged from 0.40 to 0.59, P < .05, respectively).Postural control and hip strength were independently related to physical activity behavior. A sedentary behavior may be an important risk factor for impaired postural control and hip muscles strength, and that physical fitness is vital to neuromuscular outcomes.
