AB0428 The association between physical activity measured by actigraphy and fatigue in patient with rheumatoid arthritis

BackgroundPrevious studies showed that fatigue in RA is related to pain and disability, and to several psychosocial factors including coping and cognitions. Physical activity patterns, especially a pervasively passive pattern,are...

Night eating syndrome (NES) is a delayed pattern of energy intake. It is unknown if symptoms associated with this syndrome are accompanied by a delayed pattern of physical activity. This study examines the relationship between physical activity patterns and delayed eating behaviors in children. Children from the QUALITY cohort (n = 269, 45% female, aged 8-11 y) completed the Night Eating Questionnaire (NEQ), which measures NES symptoms on a continuous scale and identifies single NES symptoms. Daily accelerometer data were transformed into mean counts per wear-time minute for each hour of the day. Children with high NEQ scores had higher levels of daily (p < 0.001) and evening physical activity (p = 0.05) and reached 75% of their total daily physical activity 20 minutes later than children with low NEQ scores (p < 0.05). Excessive evening snacking and a strong urge to eat in the evening or at night were the symptoms most related to these physical activity patterns. Children with delayed eating behaviors had higher levels of physical activity in the late morning and evening and a delayed physical activity pattern compared to children with no or fewer symptoms. Future research is needed to determine if physical activity plays a role in the onset or maintenance of night eating.

ABSTRACTPurposeThis study aimed to identify physical activity patterns and examine their association with cardiometabolic biomarkers in a cross-sectional design.MethodsOverall 6072 participants (mean age, 60.2 yr; SD 8.6 yr, 50% women) from The Maastricht Study provided daily physical activity data collected with thigh-worn activPAL3 accelerometers. The patterns of daily physical activity over weekdays and weekend days were identified by using Group Based Trajectory Modeling. Cardiometabolic biomarkers included body mass index, waist circumference, office blood pressure, glucose, HbA1c, and cholesterol levels. Associations between the physical activity patterns and cardiometabolic outcomes were examined using the analyses of covariance adjusted for sex, age, education, smoking, and diet. Because of statistically significant interaction, the analyses were stratified by type 2 diabetes status.ResultsOverall, seven physical activity patterns were identified: consistently inactive (21% of participants), consistently low active (41%), active on weekdays (15%), early birds (2%), consistently moderately active (7%), weekend warriors (8%), and consistently highly active (6%). The consistently inactive and low active patterns had higher body mass index, waist, and glucose levels compared with the consistently moderately and highly active patterns, and these associations were more pronounced for participants with type 2 diabetes. The more irregular patterns accumulated moderate daily total activity levels but had rather similar cardiometabolic profiles compared with the consistently active groups.ConclusionsThe cardiometabolic profile was most favorable in the consistently highly active group. All patterns accumulating moderate to high levels of daily total physical activity had similar health profile suggesting that the amount of daily physical activity rather than the pattern is more important for cardiometabolic health.

Physical activity is usually considered as an important component of a healthy lifestyle, including a preventive effect on the risk of falls in the elderly. The relationship between physical activity and falls is complex: physical activity is a prerequisite to maintain neuromuscular functioning, necessary to keep balance and to react to a fall, but a higher level of physical activity also implies a greater exposure to environmental threats, possibly leading to a fall. Related to this greater exposure to threats, the use of a walking aid may protect against falls in those who have impaired mobility. In this cross-sectional study we investigated the relationship between daily physical activity and falls and the use of a walking aid in elderly subjects. Participants were 131 men and 563 women, aged 70 years and over (mean age and standard deviation: 82+/-6 years), living in homes for the elderly (n=335) and apartment houses for elderly (n=359). Data on baseline characteristics and falls in the previous year were obtained using a questionnaire. The level of daily physical activity in the previous year was obtained by means of a questionnaire regarding household and leisure activities. Subjects with a lower extremity fracture in the previous year were excluded from the analyses. Data were analysed using multiple logistic regression, adjusted for age, gender, and residence. In the past year, 40% of the participants fell at least one time, and 19% of the participants fell two times or more. Since falls and recurrent falls were nonlinearly related to the level of daily physical activity, the physical activity score was grouped into quartiles: the highest quartile corresponding to the highest activity level. Odds ratios (and 95% confidence intervals) for falls and recurrent falls for subjects in the highest quartile contrasted with those in the lowest quartile were 0.5 (0.3-0.9) and 0.3 (0.2-0.6), respectively. The risk of falls and recurrent falls was not lower for those with intermediate levels of daily physical activity. The use of a walking aid protected against falls in those with intermediate high activity levels (third quartile). It was suggested that the exposure to environmental hazards, due to some degree of physical activity may have been responsible for the nonlinear relationship between daily physical activity and falling. We conclude that a high activity level and the use of a walking aid may protect against falls.

Background:Physical activity is an important non-pharmacological intervention that has a combination of biological, physical and psycho-social benefits and can positively influence chronic fatigue in patients with rheumatoid arthritis (RA) [1, 2, 3].Objectives:Evaluation of the effectiveness of the use of aerobic exercise (walking) to reduce fatigue in RA patients.Methods:The study included 111 women with RA (mean age 54.4 ± 11.03 years old, mean duration of illness - 11.9 ± 9.3 years old). The DAS28-ESR indicator in RA patients was 2.84 [2.32; 3.05] points: low disease activity was diagnosed in 61.3% of patients, and remission in 38.7%. The average level of fatigue according to the VAS screening scale was 71.6 ± 8.93 points. Fatigue was assessed using the Bristol Rheumatoid Arthritis Fatigue Numerical Rating Scale (BRAF-NRS V2). To assess the patient’s tolerance to physical activity, a 6-minute walking distance (6MWD) test was used. A walking test at 50 meters was used to assess the functional state of patients in dynamics. The rehabilitation program (RP) of patients (for 21 days) included morning hygienic gymnastics, dosed walking (daily, duration 30-60 minutes) and walking in the air up to 3-3.5 hours a day. Vigorous movements “through pain” were contraindicated.Results:No association was found between the duration of RA and all of the used numerical fatigue scales (p&gt; 0.05), but there was a weak positive relationship between VAS and NRS-overcoming with age (r = 0.21 and r = 0.28). An association between DAS28-ESR and numerical fatigue scales VAS (r = 0.21), NRS effect (r = 0.25) and NRS - overcoming (r = 0.24) was found, despite the fact that this study did not include patients with moderate and high RA activity.There was a significant correlation between the walking time and the number of steps during the 50-meter test (r = 0.6, p &lt;0.001), as well as an association between the fatigue and the walking time (r = 0.33, p = 0.001 for VAS and r = 0.41, p &lt;0.001 for NRS-severity) and the number of steps (r = 0.39, p &lt;0.001 for VAS; r = 0.47, p &lt;0.001 for NRS-severity; r = 0.44, p &lt;0.001 for NRS-bridging).Table 1.Dynamics of fatigue levels and physical indicators in RA patientsBefore RPIn the end of RPрVAS fatigue level71,2 ± 9,08 (71,5; 64–78)70,4 ± 9,15 (70; 64–78)p&gt;0,05BRAF-NRS: severity6,83 ± 1,21 (7; 6–8)6,51 ± 1,18 (7; 6–7)p&lt;0,01BRAF-NRS: effect6,24 ± 1,07 (5; 4–6)5,95 ± 1,08 (6; 5–7)p&lt;0,05BRAF-NRS: overcoming5,0 ± 1,7 (7; 6–8)7,76 ± 1,37 (5; 4–5)p&gt;0,0550 meter test, number of steps79,3 ± 8,64 (78; 73–84)78,91 ± 8,15 (78; 73–83)p&gt;0,0550-meter test, walking time, seconds56,7 ± 8,72 (57; 50–63)55,9 ± 8,59 (56; 51–60)р=0,01* The data are presented as mean ± standard deviation (median; interquartile range)After the completion of RP (Table), RA patients showed a significant reduction in the aspects of fatigue according to the NRS-severity (Z = 2.98, p = 0.003) and NRS-effect (Z = 2.08, p = 0.037) scales. There was also a decrease in the time spent by patients performing the 50 m walking test (t = 2.63, p = 0.01), but the total number of steps did not change (t = 1.44, p = 0.154). Fatigue and pain are important barriers to physical activity, but it is severe fatigue that reduces physical activity in patients with RA [4]. At the same time, physical activity itself can become a factor in reducing fatigue [5], including by reducing the activity of the disease [6].Conclusion:The severity of fatigue in RA patients can be reduced by actively using non-pharmacological treatment strategies. Walking is a simple and effective solution to increase physical activity and it has a significant effect on fatigue in RA.

Introduction Sleep and physical activity habits during childhood are influenced by developmental, cultural and environmental factors. Poor sleep is associated with lower immune function, physical activity levels, and psychological functioning, thus contributing to a vicious cycle of increased vulnerability during this developmental period. Regular physical activity, in turn, is associated with better sleep, improved immune function, and higher psychological well-being. There is, however, a lack of research on sleep and physical activity patterns in Sub-Saharan Africa, especially among children from marginalized areas. Therefore, the present study has two objectives: First, it aims to fill a gap in the literature by reporting sleep and physical activity patterns among primary schoolchildren aged 6-12 years from Tanzania (Ifakara: N = 845), South Africa (Gqeberha: N = 1,287), and Côte d’Ivoire (Taabo: N = 1,027). Second, to investigate the relationship between habitual physical activity (7-day actigraphy) and sleep (parental and self-reported). Methods Thousand three-hundred and twenty children aged 5-12 years from each country were recruited. Sleep. Parents were asked to complete a few sleep-related questions regarding their child`s bed- and rise times. To assess sleep quality, children completed questions from the Pittsburgh Sleep Quality Index (Buysse et al., 1989). To screen for sleep disturbances, children also answered three items of the Insomnia Severity Index (Morin et al., 2011), addressing difficulty falling asleep, staying asleep and waking up too early in the morning. Physical Activity. Objective physical activity was assessed with an accelerometry (Actigraph wGT3x-BT, Shalimar, FL, USA) worn around the hip. The device was worn for 7 consecutive days to assess a full weekly period, with a sampling epoch of 15 sec (Rowlands, 2007). Time per day spent in MPA (&gt;3 MET [metabolic equivalents of task]) and VPA (&gt;6 MET) is determined based on the raw accelerometry counts and the ActiLife computer software, with cut-off values derived from Freedson et al. (1998). The ActiGraph accelerometrys have been validated with children (Crouter et al., 2013; Hänggi et al., 2013). Results Children assessed in Côte d’Ivoire and Tanzania showed higher levels of daily physical activity (MVPA) than those assessed in South Africa. Yet, mean group levels still exceeded the recommended amount of 60 min MVPA/day. Across all three countries, boys generally had higher MVPA levels than their female peers, and children from the poorest wealth quintile were also more active than their peers from the least poor quintile. Composite sleep health was significantly different between countries, with the highest scores reported in Tanzania, followed by Côte d’Ivoire and South Africa. After controlling for sex, it was found that MVPA significantly predicted composite sleep health among children in Tanzania (ß = 5.83, p = .002) and Côte d’Ivoire (ß = 3.41, p = .072), but not in South Africa (ß = 0.67, p &gt; .05). Discussion/Conclusion Adequate sleep and physical activity is crucial for children’s physical and mental development. Most of our understanding of the relationship between daily physical activity and sleep patterns is based on research conducted in Western high income countries. Currently, little is known about this association in children from Sub-Saharan African, specifically primary schoolchildren living in marginalized areas in Tanzania, South Africa, and Côte d’Ivoire. Results will reveal whether research from high-income countries is generalizable to low- or middle-income countries, and inform health policy makers on points for prevention and intervention in school-based settings.

Deviations in daily physical activity patterns in patients with the chronic fatigue syndrome: A case control study

Relationship between patterns of daily physical activity and fatigue in cancer survivors

Previous studies examining the cardiometabolic risks associated with physical activity (PA) in workers have predominantly used self-reported measures. Little is known about workers' distinct daily PA patterns and whether these are linked with cardiometabolic risks. This study examined associations between patterns of workers' accelerometer-measured daily PA and four markers of cardiometabolic health. Working adults (N=8,229; 47% women; average age: 42 years; standard deviation = 0.3) were sampled from the Canadian Health Measures Survey (five cycles: 2007 to 2017). Accelerometer devices measured daily PA, and hierarchical cluster analysis identified distinct activity patterns. Multiple linear regression analyses examined associations between activity patterns and cardiometabolic risk markers (waist circumference, systolic and diastolic blood pressure, and non-high-density lipoprotein [HDL] cholesterol). Workers were classified into six distinct activity patterns. On average, compared with workers classified in the "lowest activity" pattern, workers with the "moderate consistent activity," "fluctuating moderate activity," "high daytime activity" and "highest activity" patterns were associated with lower waist circumferences; workers with the "fluctuating moderate activity" and "highest activity" patterns were associated with lower systolic blood pressure; the "moderate evening activity" pattern was associated with lower diastolic blood pressure; and workers with the "fluctuating moderate activity," "high daytime activity" and "highest activity" patterns were associated with lower non-HDL cholesterol. "High daytime activity" was associated with lower waist circumference in women, compared with men, and the "moderate consistent activity" and "fluctuating moderate activity" patterns were associated with lower diastolic blood pressure in younger workers (40 years or younger). Workers with high daily PA levels tended to have the most optimal cardiometabolic health. Some evidence suggested that there are benefits to moderate levels of PA, particularly for lowering waist circumference and non-HDL cholesterol. Findings may assist in identifying workers for PA initiatives to promote cardiometabolic health benefits.

BackgroundThe effect of high levels of physical activity and relationship between daily total physical activity and the risk of cardiovascular disease (CVD) among hypertensive people were not clear. This study aimed to explore the optimum level of physical activity for CVD prevention.MethodsData used in the present study was derived from the sub-study of China Kadoorie Biobank study (CKB) in Jiangsu province of China. The CKB was a prospective cohort study established during 2004–2008. At baseline, 53,259 participants aged 35–74 years were recruited for the CKB Jiangsu sub-study conducted in Wuzhong district of Suzhou City. Among those 53,259 participants, the 20,179 hypertensive individuals were our study population. The outcome events were cardiovascular diseases (CVDs), while the independent variable was total daily physical activity. The Cox proportional hazard models were introduced to investigate the association between total physical activity and CVDs, reporting as hazard ratios (HR) and 95% confidence intervals (CIs).ResultsDuring a 10.1-year follow-up, 2419 CVD cases were identified. After adjustment for potential confounding factors, compared with participants at the lowest level of daily total physical activity, the hazard ratios for CVDs were 0.87 (95%CI: 0.79–0.97), 0.73 (95%CI: 0.65–0.83) and 0.75 (95%CI: 0.65–0.85) for participants within 2, 3 and 4 quartiles of physical activity. Such a negative association between total physical activity and CVDs were also observed among participants by gender and age-group, but within patients with stage 1 hypertension only. Moreover, the association of physical activity with CVDs was U-shape and the lowest HR (0.63, 95%CI: 0.54–0.74) was observed at 35.4 MET-h/d of total physical activity.ConclusionsTotal daily physical activity was negatively associated with CVDs among hypertensive adults in China, and this association was U-shape. It has some public health implications that community-based total physical activity intervention campaigns can be of help for CVDs prevention among hypertensive people in China.

Lack of knowledge about the causes of fatigue often leads to ignoring this symptom in rheumatoid arthritis (RA). The severity of fatigue in patients with RA can be significantly reduced by actively using non-pharmacological treatment strategies. Aim. To evaluate the effectiveness of aerobic exercise (walking) to reduce fatigue in RA patients during long-term follow-up. Material and methods. The study involved 102 patients with RA (women 100%; average age 54.38 ± 11.3 years; disease duration 9.5[5;15] years; DAS28-ESR activity 2.85[2.32;3.06] points; fatigue on the VAS scale ≥50), who completed the stage of sanatorium treatment in full (21 days) and provided data on aerobic physical activity (steps quantity per day) and fatigue scores on the British Rheumatoid Arthritis Fatigue Scale – Numerical Rating Scale (BRAF-NRS V2). RA patients were divided into two groups according to their level of physical activity: group I (n=53) with a sedentary lifestyle (less than 5–6 thousand steps/day) and group II (n=49) with a recommended (mobile) lifestyle (more than 7–8 thousand steps/day). Assessment of RA patients’ adherence to physical activity was carried out 2 months after return from the sanatorium, and the dynamics of BRAF-NRS fatigue indexes were recorded. Results and discussion. Seventy-six people (74.5%) agreed to participate in the final survey: 32 patients from a group I and 44 patients from a group II. Commitment to daily aerobic activity (more than 5,000 steps per day) was maintained by 34% of participants in the group I and 59% in the group II (p=0.033). The majority of respondents (51.3%) decreased the physical activity level and significantly reduced the time for aerobic exercise after returning from the sanatorium, citing a lack of incentives and time. 47% of the group I patients (15/32) felt able to devote more attention to physical activity, but only 25% confirmed a strong belief that they would dedicate at least 30 minutes to aerobic exercise 5 times a week over the next three months. In the group II, 48% of patients (p=0.044) reported maintaining or even increasing the corresponding physical activity level, confirming the effectiveness of individual physical activity programs formed during the sanatorium treatment and then integrated into daily life. Two months after returning from the sanatorium, group II patients showed lower fatigue scores on all BRAF-NRS scales: NRS-severity (p=0.04), NRS-effect (p=0.005), and NRS-overcoming (p=0.034). The analysis of variance revealed a decrease in the level of fatigue in the medium term (up to 2 months) regardless of the level of physical activity of the patients, but in RA patients committed to an active lifestyle and regular aerobic physical activity (group II), the positive changes were most pronounced (p&lt;0.001). Conclusion. The positive effect of aerobic exercise (walking) on reducing fatigue is significantly negated even in the med-term, if patients do not continue to lead an active lifestyle. After completion of the sanatorium stage of treatment (with selection of optimal dose and frequency of physical activity), RA patients should be further encouraged to do daily aerobic exercises and be supported to continue rehabilitation programs in the community in order to achieve a better effect in the long term.

Higher levels of physical activity are associated with reduced cardiovascular mortality but its effect on age-related changes in cardiac structure and function is unknown. The present study defines the effect of daily physical activity on age-related changes in cardiac structure, function, metabolism, and performance in healthy women. Sixty-three healthy women were grouped according to age (young, 20-30 years, n=21; middle, 40-50 years, n=22; and older, 65-81 years, n=20) and daily physical activity level (low active<7500 and high active>12,500 steps/d). Participants underwent cardiac MRI including tissue tagging and 31P spectroscopy and exercise testing with noninvasive central hemodynamic measurements. Aging was associated with increased concentric remodeling (P<0.01) and left ventricular torsion (P<0.01), and a decline in diastolic function (P<0.01), cardiac phosphocreatine:ATP ratio (P<0.01), peak exercise cardiac power output (P<0.01), and O2 consumption (P<0.01). Older high-active women demonstrated a phosphocreatine:ATP ratio and relative peak O2 consumption similar to young low-active women, and 23% and 26% higher than older low-active women (phosphocreatine:ATP ratio, 1.9±0.2 versus 1.4±0.1; P<0.05 and O2 consumption, 24.1±3.8 versus 17.8±2.0 mL/[kg·min]; P<0.01). In older women, physical activity had no effect on eccentricity ratio (0.9±0.2 versus 0.8±0.1 g/mL; P=0.19), E/A ratio (1.3±0.5 versus 1.4±0.5; P=0.66), torsion (7.6±1.7 versus 8.0°±2.1°; P=0.20), and peak cardiac power output (3.4±0.7 versus 3.4±0.8 W; P=0.91). A higher level of daily physical activity preserves cardiac metabolism and exercise capacity with aging but has limited effect on age-related changes in concentric remodeling, diastolic function, and cardiac performance.
