Purpose
To get insight into the potential significance of objectively measured sedentary time (ST), and physical activity (PA) intensity levels on sleep quality (SQ) in women with fibromyalgia; and ...to assess whether those who meet moderate‐to‐vigorous PA (MVPA) recommendations have better SQ than their counterparts.
Methods
Four‐hundred and nine women with fibromyalgia (age range 30‐65 years old) from Andalusia (southern Spain) were included in this cross‐sectional study. Sedentary time, PA intensity levels (light, moderate, and MVPA), and total PA were assessed with accelerometers during seven consecutive days. Sleep quality was measured with the Pittsburgh Sleep Quality Index self‐report questionnaire.
Results
Higher ST was associated with worse subjective SQ, sleep duration, sleep disturbances, daytime dysfunction, and SQ global score (all, P < 0.05). All PA levels were associated with better subjective SQ and sleep latency and with less sleep medication and daytime dysfunction (all, P < 0.05). In addition, light and total PA were associated with better sleep efficiency, SQ global score, and less sleep disturbances (all, P < 0.05). Finally, women meeting bouted PA recommendations displayed better SQ than patients not meeting the recommendations (bouted or non‐bouted).
Conclusion
Lower ST and greater PA levels are associated with better SQ in women with fibromyalgia. This result demonstrates that those patients with fibromyalgia who reduce periods of inactivity and perform PA could be better sleepers, which might contribute to a lower severity of the disease. It is noteworthy that meeting bouted PA recommendations is associated with better SQ.
Objective
To analyze changes over time and the predictive value of baseline and changes of sedentary time (ST) and physical activity (PA) on pain, disease impact, and health‐related quality of life ...(HRQoL) at 2‐ and 5‐year follow‐up in women with fibromyalgia.
Methods
This is a longitudinal and exploratory study with three time points. A total of 427 women with fibromyalgia (51.4 ± 7.6 years) were followed after 2 (n = 172) and 5 years (n = 185). ST and PA (light and moderate‐to‐vigorous MVPA) were assessed using triaxial accelerometers. Pain, disease impact, and HRQoL were measured using: pressure pain threshold, the pain subscale of the revised fibromyalgia impact questionnaire (FIQR), the bodily pain subscale of the 36‐item short‐form health survey (SF‐36), a visual analog scale (VAS), the FIQR, and the SF‐36 physical and mental components.
Results
Over 5 years, pressure pain threshold, ST, light PA, and MVPA variables were worsened, while FIQR and SF‐36 variables were improved (Cohen's d < 0.1–0.3). Baseline ST or light PA were not associated with future outcomes, whereas greater MVPA at baseline was associated with better SF‐36 bodily pain at 5‐year follow‐up (β = 0.13). Reducing ST and increasing light PA were associated with better bodily pain (β = −0.16 and 0.17, respectively) and SF‐36 physical component (β = −0.20 and 0.17, respectively) at 5‐year follow‐up. Increasing MVPA was associated with less pain (pressure pain threshold, VAS, and FIQR‐pain) and better SF‐36 physical component at 2‐ and 5‐year follow‐up (β's from −0.20 to 0.21).
Conclusions
Objectively measured variables slightly worsened over years, while for self‐reported outcomes there was a trend for improvement. Reductions in ST and increases in light PA and MVPA were associated with better HRQoL at 5‐year follow‐up, and increases in MVPA were additionally associated with better pain and HRQoL at 2‐year follow‐up.
Objective
There is an overall awareness of the detrimental health effects of sedentary time (ST) in fibromyalgia; however, data are limited on how replacement of ST with physical activity (PA) of ...different intensity may be related to health in this condition. The aim of this study was to examine how a substitution of ST with light PA (LPA) or moderate‐to‐vigorous PA (MVPA) is associated with quality of life and disease impact.
Methods
This study comprised 407 women with fibromyalgia, mean ± SD age 51.4 ± 7.6 years. The time spent in ST and PA was measured with triaxial accelerometry. Quality of life and disease impact were assessed using the Short Form 36 (SF‐36) health survey and the Revised Fibromyalgia Impact Questionnaire (FIQR), respectively. The substitution of ST with an equivalent time of LPA or MVPA and the associated outcomes were examined using isotemporal substitution analyses.
Results
Substituting 30 minutes of ST with LPA in the isotemporal model was associated with better scores in bodily pain (B = 0.55), vitality (B = 0.74), and social functioning (B = 1.45) according to the SF‐36, and better scores at all of the domains (function, overall impact, symptoms, and total impact) of the FIQR (B ranging from –0.95 to –0.27; all P < 0.05). When ST was replaced with MVPA, better physical role (B = 2.30) and social functioning (B = 4.11) of the SF‐36 and function of the FIQR (B = –0.73) were observed (all P < 0.05).
Conclusion
In regression models, allocation of time of sedentary behavior to either LPA or MVPA was associated with better quality of life and lower disease impact in women with fibromyalgia.
Objective
To characterize the levels of objectively measured time spent in sedentary activities (sedentary time) and physical activities in female patients with fibromyalgia and compare them with the ...levels in age‐matched healthy control women.
Methods
The study comprised 413 female patients with fibromyalgia (mean ± SD age 51.9 ± 7.4 years) and 188 female control subjects (age 50.9 ± 7.5 years). Sedentary time, the amount of time spent engaged in physical activity, and step counts were measured using triaxial accelerometry. The amounts of time (minutes/day) during which the participants were engaged in sedentary behaviors as well as in physical activity of different intensities (light, moderate, and moderate‐to‐vigorous) and the step counts were calculated.
Results
The amount of time spent in sedentary behavior was longer in patients with fibromyalgia compared with controls (estimated mean ± SEM difference 39 ± 8 minutes/day; P < 0.001). The patients with fibromyalgia spent less time than controls engaged in light physical activity (mean ± SEM difference −21 ± 7 minutes/day; P = 0.005), moderate physical activity (mean ± SEM difference −17 ± 3 minutes/day; P < 0.001), and moderate‐to‐vigorous physical activity (mean ± SEM difference −19 ± 3 minutes/day; P < 0.001). The patients with fibromyalgia took fewer steps/day compared with the control subjects (mean ± SEM difference −1,881 ± 262 steps/day; P < 0.001). Only 20.6% of the patients with fibromyalgia and 46.3% of the control subjects fulfilled the recommendation for 150 minutes/week of moderate‐to‐vigorous physical activity in bouts of at least 10 minutes/bout (χ2 = 41.8, P < 0.001). Similarly, only 16.0% of the patients fulfilled the recommendation for ≥10,000 steps/day compared with 44.7% of the control subjects (χ2 = 56.8, P < 0.001). Both the patients and the control subjects were more active (physical activity of all intensities and numbers of steps) on weekdays than on weekend days (all P ≤ 0.001).
Conclusion
Female patients with fibromyalgia spent more time in sedentary behaviors and were less physically active than age‐matched controls. The low proportions of female patients with fibromyalgia and control subjects who met the physical activity and step count recommendations is worrisome.
Abstract Objectives To characterize a representative sample of fibromyalgia women based on a set of relevant factors known to be related to this disease. To distinguish specific factors of the ...disease from other symptoms that might also exist in non-fibromyalgia women. To test whether fibromyalgia affects more severely physical or psychological outcomes. Methods A total of 459 fibromyalgia women vs. 214 non-fibromyalgia (control) women from Southern Spain (Andalusia) took part in this cross-sectional study. Several instruments were used to assess tenderness, impact of fibromyalgia, fatigue, health-related quality of life, mental health, and cognitive performance. Results Overall, fibromyalgia women showed a worse status in pain, fatigue, health-related quality of life, depression, and anxiety than controls ( P < 0.01). In general, the observed associations presented very large effect sizes (Cohen׳s d from ~1 to ~5.5). No differences between fibromyalgia and controls were observed in cognitive and memory performance, except for delayed recall, but the observed effect size was low (~0.25). The effect size observed for the global physical component (~3.3) was larger than that for the global psychological component (~1.3), all P < 0.001. Conclusions Our results reinforce the understanding of fibromyalgia as a polysymptomatic distress condition with pain as its main symptom. Our findings support that fibromyalgia seems to have a greater impact on physical than on psychological outcomes, though both are largely affected.
Objective
This population‐based cross‐sectional study aimed to characterize the association of different components of physical fitness with pain levels, pain‐related catastrophizing, and chronic ...pain self‐efficacy in women with fibromyalgia (FM).
Methods
A total of 468 women with FM participated. The experience of pain was assessed with different tools (algometry, a numeric rating scale revised FM impact questionnaire, a visual analog scale, and the bodily pain subscale on the Short Form 36 health survey). We also assessed pain‐related catastrophizing and chronic pain self‐efficacy. Physical fitness was assessed with performance‐based tests (Senior Fitness Test battery and handgrip dynamometry). A standardized composite score was computed for each component of physical fitness (aerobic fitness, muscle strength, flexibility, and motor agility), and their average comprised a clustered global fitness profile.
Results
Overall, higher physical fitness was consistently associated with lower levels of pain, lower pain‐related catastrophizing, and higher chronic pain self‐efficacy (regardless of the pain assessment method and the fitness test evaluated). Muscle strength and flexibility were independently associated with pain (P < 0.005 for both), and participants with high muscle strength plus high flexibility (combined effect) had the lowest levels of pain in this population. Aerobic fitness and flexibility were independently associated with pain‐related catastrophizing (P < 0.001 for both) and chronic pain self‐efficacy (P < 0.001 for both), and participants with high flexibility plus high aerobic fitness (combined effect) had the best catastrophizing and self‐efficacy profiles.
Conclusion
Our results suggest that higher physical fitness is associated with lower levels of pain, lower pain‐related catastrophizing, and higher chronic pain self‐efficacy in women with FM. These results might have implications for future intervention studies in this population.
We investigated which determinants (socioeconomic, early life factors, body composition changes, fitness changes and/or physical activity changes) best predicted longitudinal outcomes in ...cardiometabolic risk profile (Z-score change) in adolescents with OW/OB who underwent a 13-month multidisciplinary lifestyle intervention. A total of 165 adolescents (13–16 y; 46% boys) from the EVASYON study were included. Socioeconomic variables and early life factors were obtained from the medical records. Body composition was assessed using anthropometry. Fitness and physical activity were measured with field-based tests and questionnaires. Cardiometabolic risk factors (fasting glucose, HDL cholesterol, triglycerides, blood pressure and waist circumference) were derived from standard methods in the hospital. Body weight changes, sex and mother’s education were selected in the stepwise process as the most important determinants of changes in cardiometabolic risk profile (R2 = 0.26, p = 0.002; R2 = 0.14, p = 0.013; and R2 = 0.14, p = 0.017, respectively). Both boys and girls showed a lower cardiometabolic risk score with the reduction in body weight (r = 0.535, p = 0.009 and r = 0.506, p = 0.005, respectively). There was no interaction between sex and body weight change (p = 0.614). In conclusion, the simple measure of changes in body weight should be considered to track changes in cardiometabolic risk profile in adolescents with OW/OB.
To examine the association of objectively measured physical activity (PA) intensity levels and sedentary time with arterial stiffness in women with systemic lupus erythematosus (SLE) with mild ...disease activity and to analyze whether participants meeting the international PA guidelines have lower arterial stiffness than those not meeting the PA guidelines.
The study comprised 47 women with SLE (average age 41.2 standard deviation 13.9) years, with clinical and treatment stability during the 6 months prior to the study. PA intensity levels and sedentary time were objectively measured with triaxial accelerometry. Arterial stiffness was assessed through pulse wave velocity, evaluated by Mobil-O-Graph® 24h pulse wave analysis monitor.
The average time in moderate to vigorous PA in bouts of ≥10 consecutive minutes was 135.1±151.8 minutes per week. There was no association of PA intensity levels and sedentary time with arterial stiffness, either in crude analyses or after adjusting for potential confounders. Participants who met the international PA guidelines did not show lower pulse wave velocity than those not meeting them (b = -0.169; 95% CI: -0.480 to 0.143; P = 0.280).
Our results suggest that PA intensity levels and sedentary time are not associated with arterial stiffness in patients with SLE. Further analyses revealed that patients with SLE meeting international PA guidelines did not present lower arterial stiffness than those not meeting the PA guidelines. Future prospective research is needed to better understand the association of PA and sedentary time with arterial stiffness in patients with SLE.
To assess the association between physical fitness and fibromyalgia (FM) severity in women with FM as well as to assess whether different fitness components present an independent relation with FM ...severity.
Population-based cross-sectional study.
University facilities and FM associations.
Women with FM (N=444).
Not applicable.
FM severity was assessed with the Revised Fibromyalgia Impact Questionnaire (FIQR). Aerobic fitness (6-min walk test), muscle strength (handgrip, chair stand, and arm curl tests), flexibility (chair sit and reach and back scratch tests), and motor agility (8 foot Up and Go test) were measured with the Senior Fitness Test battery and digital dynamometry. A standardized composite score (hereafter "global fitness profile") was calculated and divided into quintiles.
Overall, physical fitness was significantly associated with the FIQR total and subscale scores, regardless of the fitness test used (all P<.05). The 6-minute walk and back-scratch tests were independently associated with the FIQR total score (R(2)=.88; both P<.005). The group with the highest global fitness profile had 16% lower FM severity than did the group with the lowest global fitness profile (P<.001).
Our results suggest that higher physical fitness is consistently associated with lower FM severity in women with FM. Aerobic fitness and flexibility present independent associations with FM severity. However, the FIQR variability explained by these fitness tests was rather low (<10%), and further research on the potential disagreement between performance-based physical fitness and different self-reported outcomes in women with FM is warranted.
To study the association of different components of physical fitness flexibility, muscle strength and cardiorespiratory fitness (CRF) and a clustered fitness score with health-related quality of life ...(HRQoL) in women with systemic lupus erythematosus (SLE) and to analyze whether participants with high fitness level have better HRQoL.
This cross-sectional study included 70 women with SLE (aged 42.5; SD 13.9 years). The back-scratch test assessed flexibility, the 30-sec chair stand and handgrip strength tests assessed muscle strength, and the 6-min walk test (n = 49) assessed CRF. HRQoL was assessed through the 36-item Short-Form Health Survey (SF-36).
Flexibility was positively associated with the physical function dimension and the physical component summary (PCS) (rpartial between 0.26 and 0.31; p<0.05), and negatively related with social functioning dimension (rpartial = -0.26; p<0.05). Muscle strength was positively associated with the physical function, physical role, bodily pain dimensions and the PCS (rpartial between 0.27 and 0.49; all p<0.05). CRF was positively associated with the physical function and bodily pain dimensions, and PCS (rpartial between 0.39 and 0.65; all p<0.05). The clustered fitness score was associated with the physical function (B = 17.16) and bodily pain (B = 14.35) dimensions, and the PCS (B = 6.02), all p<0.005. Patients with high fitness level had greater scores in the physical function, physical role, and bodily pain dimensions and the PCS, all p≤0.05.
Our study suggests that muscle strength and CRF are positively associated with HRQoL, while flexibility showed contradictory results. These findings highlight the importance of maintaining adequate fitness levels in women with SLE.
