Self-reported Physical Activity Levels Research Articles

Physical Activity, Fitness, and Long-Term Risk of Amyotrophic Lateral Sclerosis: A Prospective Cohort Study.

Observational studies have demonstrated an increased amyotrophic lateral sclerosis (ALS) risk among professional athletes in various sports. For moderately increased levels of physical activity and fitness, the results are diverging. Through a cohort study, we aimed to assess the relationship between indicators of physical activity and fitness (self-reported physical activity and resting heart rate) and long-term ALS risk. From a large Norwegian cardiovascular health survey (1985-1999), we collected information on self-reported physical activity in leisure time, resting heart rate, and other cardiovascular risk factors. Patients with ALS were identified through health registries covering the whole population. We fitted Cox proportional hazard models to assess the risk of ALS according to levels of self-reported physical activity in 3 categories (1: sedentary; 2: minimum 4 hours per week of walking or cycling; 3: minimum 4 hours per week of recreational sports or hard training), and resting heart rate modeled both on the continuous scale and as quartiles of distribution. Out of 373,696 study participants (mean 40.9 [SD 1.1] years at inclusion), 504 (41.2% women) developed ALS during a mean follow-up time of 27.2 (SD 5.0) years. Compared with participants with the lowest level of physical activity, the hazard ratio was 0.71 (95% CI 0.53-0.95) for those with the highest level. There were no clear associations between resting heart rate and ALS in the total sample. In men, the hazard ratio of ALS was 0.71 (95% CI 0.53-0.95) for those reporting moderate levels of physical activity and 0.59 (95% CI 0.42-0.84) for those reporting high levels, compared with those reporting low levels. Men with resting heart rate in the lowest quartile had 32% reduced risk of ALS (hazard ratio 0.68, 95% CI 0.49-0.94) compared with those in the second highest quartile. In women, no association was detected between neither self-reported levels of physical activity nor resting heart rate and ALS risk. Indicators of high levels of physical activity and fitness are associated with a reduced risk of ALS more than 30 years later in men, but not in women.

Monitoring handgrip strength to motivate lifestyle choices for patients with diabetes type 2 – a pragmatic randomised controlled trial

Physical strength can be an important parameter to monitor for patients with diabetes mellitus type 2 (T2DM) to promote healthy lifestyle choices. Functional measurements can contribute to healthcare advice and possibly motivate more active lifestyles. The aim of the study was to investigate whether adding measurement and feedback concerning handgrip strength (HGS) to the parameters measured for patients with T2DM at annual check-ups leads to change in physical activity (PA) level, HGS, HbA1c or waist circumference. Methods Measurement of HGS with Jamar dynamometers was added to annual check-ups for patients with T2DM by diabetes nurses in primary care with feedback about normal values for age and sex in the intervention group. The control group had standard check-ups. Change in self-reported PA level was measured with questionnaires. Results Seven clinics and 334 patients participated. The intervention led to similar effects on PA in both groups. Patients with T2DM had comparable HGS to the general public. Regression analyses showed statistically significantly higher HGS in the intervention group than in the control group at follow-up and no improvement in PA, HbA1c, or waist circumference. Increased HGS was found for older people, men, and people with normal-to-high inclusion HGS, while patients with low inclusion HGS reduced their strength levels. Conclusions Measuring HGS and giving feedback to patients with T2DM can lead to increased HGS but does not seem to affect general PA level, HbA1c, or waist circumference. People over 65 years, men, and people with normal-to-high HGS were influenced positively by the intervention. Patients with low HGS may need personalised support to increase physical activity and improve function. ClinicalTrials registration: NCT03693521

A cross-sectional analysis between physical activity levels, weight status and empathy-related behaviors in a sample of Tuscany primary school children.

The present study aimed to investigate the relationship between physical activity (PA) and the development of relational empathy skills in children, taking into account weight status. Parents/guardians of primary school children were involved in filling out a questionnaire: the Empathy Questionnaire (EmQue-I13) and children were asked to complete the Physical Activity Questionnaire for Children (PAQ-C) to investigate the self-reported PA levels. The weight status was assessed using a self-reported Body Mass Index (BMI). Three hundred seventy parents or guardians of students who attended primary school (8.53±1.61 yrs) were recruited. The total score was 2.41±0.89 for PAQ-C and 41.17±6.32 for EmQue-I13. The three domains of EmQue-I13 were: contagion (8.16±2.67), attention to others' feelings (19.40±2.99) and prosocial actions (13.62±3.01). Linear regression models showed that a higher PAQ-C score was positively associated with empathy-related total score P<0.000. Weight status, age and gender were not associated with EmQue-I13. Our results underline the positive association between physical activity and the development of relational empathic skills.

Nonparticipation Bias in Accelerometer-Based Studies and the Use of Propensity Scores

Relatively little attention has been paid to the effects of nonparticipation on data quality in population-based studies that use accelerometers to measure physical activity. We examine these issues using data from the 2013 Longitudinal Internet Studies for the Social Sciences (LISS) panel and 2013–2014 National Health and Nutrition Examination Survey (NHANES) accelerometer studies, both of which collected survey data in advance and therefore permit comparisons of self-reported physical activity between participants and nonparticipants to the accelerometer studies. While individuals with high levels of self-reported physical activity are overrepresented in the participant samples, the differences are modest in both studies. However, in the LISS panel this difference led to overestimates of physical activity that are not fully corrected by propensity score weighting adjustments (i.e., non-ignorable selection bias). This finding underscores the importance of assessing the potential influence of nonparticipation on accelerometer-derived estimates of physical activity.

Evaluating knowledge, attitude, and physical activity levels related to cardiovascular disease in Egyptian adults with and without cardiovascular disease: a community-based cross-sectional study

BackgroundCardiovascular disease (CVD) represents a significant health challenge in Egypt, yet there exists limited understanding regarding the knowledge, attitudes, and physical activity levels associated with CVD. These factors play a pivotal role in developing effective prevention and management strategies. Hence, this cross-sectional study aimed to evaluate Egyptian adults’ knowledge, attitudes, and physical activity (KAP) levels.MethodsData were collected using a previously validated questionnaire encompassing demographic characteristics, CVD knowledge (including risk factors and symptoms), attitudes toward CVD, and self-reported physical activity levels. The survey was distributed among social media channels, and trained researchers administered the questionnaire via face-to-face interviews with adult patients with and without CVD admitted to Cairo University Hospital clinics.ResultsThe study involved 591 participants, of whom 21.7% had CVD. Overall, participants exhibited poor knowledge regarding CVD, with a mean score of 21 ± 7 out of 40, equivalent to 52.5%. Attitudes toward CVD were moderate, with a mean score of 66.38 ± 8.7 out of 85, approximately 78%. Physical activity levels per week were also moderate, averaging 1188 MET-min with a range of 1121–18,761. Subgroup analysis revealed that individuals with CVD had lower average knowledge, attitude, and physical activity levels than those without CVD. Working in the healthcare field was a predictor of higher knowledge score (standard error (SE) 5.89, 95% confidence interval (CI) 4.61 to 7.17, P < 0.001), while those with CVD and smokers were predictors of lower attitude score (SE -4.08, 95% CI -6.43 to -1.73, P < 0.001) and (SE -2.54, 95% CI -4.69 to -0.40, P = 0.02), respectively.ConclusionThe study findings highlight a significant disparity in knowledge, attitudes, and physical activity levels related to CVD in Egypt. Targeted interventions aimed at improving awareness, fostering positive attitudes, and promoting physical activity among individuals at risk for CVD are crucial for effective prevention and management.

Psychological correlates of physical activity among adults living in rural and urban settings.

Middle-aged and older adults living in rural settings have been consistently less likely to report regular physical activity (PA) than those living in urban settings. While past literature has identified sociodemographic and environmental correlates of PA that may contribute to these differences, consideration of psychological correlates has been limited. A total of 95 rural and urban adults ≥50 years old provided self-reported sociodemographic information, PA level, and psychological correlates of PA including measures assessing motivation, self-efficacy, social support, and attitudes related to PA. The average participant age was 68.6 years, and most were female (62.1%) and married (70.5%). While PA level did not differ significantly between the rural and urban groups, different psychological correlates contributed significantly to separate rural and urban linear regression models considering PA status. Among rural adults, more positive attitudes toward PA, and greater PA self-efficacy and social support were associated with greater amounts of PA while for urban adults, no psychological correlates were significantly associated with PA. Psychosocial factors may be key considerations in developing more effective PA interventions in middle-aged and older adults living in rural areas.

Delving into the relationship between regular physical exercise and cardiac interoception in two cross-sectional studies

Cardiac interoception, the ability to sense and process cardiac afferent signals, has been shown to improve after a single session of acute physical exercise. However, it remains unclear whether repetitive engagement in physical exercise over time leads to long-term changes in cardiac interoceptive accuracy. It is also unknown whether those changes affect the neural activity associated with the processing of afferent cardiac signals, assessed by the heart-evoked potential (HEP). In this study, we aimed to investigate this hypothesis through two cross-sectional studies, categorizing participants as active or inactive based on physical fitness (Study I; N = 45) or self-reported physical activity levels (Study II; N = 60). Interoception was assessed at rest using the HEP (Studies I and II), the Heartbeat Counting task (Study II), and the Rubber Hand Illusion (RHI) (Study II). Study I showed strong evidence of better cardiovascular fitness in the active group than in the inactive group as well as robust between-group differences in electrocardiogram (ECG) recordings. Study 2 replicated the clear differences in ECG as a function of regular physical activity. Those results were expected due to clear differences in physical activity habits. In contrast, our analysis revealed no robust differences between groups across cardiac interoception tasks and the RHI, although the direct relevance of these measures to interoception remains under investigation. In sum, our results do not provide convincing evidence to support a strong version of the notion that regular physical exercise is associated with an enhanced in cardiac interoception.

Low physical activity is a risk factor for sarcopenia: a cross-sectional analysis of two exercise trials on community-dwelling older adults

BackgroundPhysical inactivity is an important factor in the development of sarcopenia. This cross-sectional study explores the prevalence of sarcopenia and associations of physical activity (PA) with sarcopenia in two exercise trial populations. These study groups are clinically meaningful community-dwelling populations at increased risk for sarcopenia: older adults not meeting the PA guidelines and those with a recent hip fracture (HF).MethodsData from 313 older adults who did not meet the PA guidelines (60% women; age 74.5 ± 3.8, body mass index 27.9 ± 4.7) and 77 individuals with HF diagnosed on average 70 ± 28 days earlier (75% women; age 79.3 ± 7.1, body mass index 25.3 ± 3.6) were included in this study. Grip strength and muscle mass (Dual-energy X-ray absorptiometry [DXA] in older adults not meeting the PA guidelines and bioimpedance analysis in participants with HF) were used to assess sarcopenia according to the European Working Group in Older People 2019 (EWGSOP2) criteria. The current level of PA was self-reported using a question with seven response options in both study groups and was measured with a hip-worn accelerometer for seven consecutive days in older adults not meeting the PA guidelines.ResultsThe prevalence of sarcopenia and probable sarcopenia was 3% (n = 8) and 13% (n = 41) in the older adults not meeting the PA guidelines and 3% (n = 2) and 40% (n = 31) in the HF group, respectively. In the age- and sex-adjusted logistic regression model, the lowest levels of self-reported PA were associated with increased probable sarcopenia and sarcopenia risk in older adults not meeting the PA guidelines (OR 2.8, 95% CI, 1.3–6.1, p = 0.009) and in the HF group (OR 3.9, 95% CI, 1.4–11.3, p = 0.012). No significant associations between accelerometer-measured PA and probable sarcopenia or sarcopenia were found.ConclusionsProbable sarcopenia is common among community-dwelling older adults not meeting the PA guidelines and very common among individuals recovering from HF who are able to be involved in exercise interventions. In addition, since low PA is associated with higher probable sarcopenia and sarcopenia risk, it is recommended to screen for sarcopenia and promote regular physical activity to prevent sarcopenia in these populations.

Influence of the Fear of Movement and Fatigue on Self-Efficacy for Physical Activity in Women with Fibromyalgia

Introduction and purpose: Self-efficacy is considered an antecedent for physical activity levels in fibromyalgia patients. However, the influence of the fear of movement and fatigue on the self-efficacy to reduce physical inactivity is still not clear and could be critical in improving the biopsychosocial benefits of therapeutic exercise. In this way, the present study aims to assess the relationship between self-efficacy, fatigue, fibromyalgia impact, the fear of movement, and physical activity. Additionally, it aims to explore differences among patients based on self-reported physical activity levels. Material and methods: A sample of 115 women diagnosed with fibromyalgia were evaluated in this prospective study. The variables were the impact of fibromyalgia, the fear of movement, fatigue, self-efficacy, and physical activity levels. Results: Patients with high and moderate physical activity levels had higher self-efficacy for physical function (p &lt; 0.05), which is in line with the previously known model. Furthermore, a model was developed where the significant relationship between the fear of movement and self-efficacy for physical activity was significantly mediated by general fatigue and the impact of fibromyalgia on physical function. Conclusions: The fear of movement may influence self-efficacy, affecting physical activity levels; therapeutic exercises targeting the fear of movement can enhance self-efficacy and activity levels, while fatigue and fibromyalgia may mediate this relationship.

Effects of physical exercise during adjuvant chemotherapy for breast cancer on long-term tested and perceived cognition: results of a pragmatic follow-up study

PurposeCancer-related cognitive impairment (CRCI) following chemotherapy is commonly reported in breast cancer survivors, even years after treatment. Data from preclinical studies suggest that exercise during chemotherapy may prevent or diminish cognitive problems; however, clinical data are scarce.MethodsThis is a pragmatic follow-up study of two original randomized trials, which compares breast cancer patients randomized to exercise during chemotherapy to non-exercise controls 8.5 years post-treatment. Cognitive outcomes include an online neuropsychological test battery and self-reported cognitive complaints. Cognitive performance was compared to normative data and expressed as age-adjusted z-scores.ResultsA total of 143 patients participated in the online cognitive testing. Overall, cognitive performance was mildly impaired on some, but not all, cognitive domains, with no significant differences between groups. Clinically relevant cognitive impairment was present in 25% to 40% of all participants, regardless of study group. We observed no statistically significant effect of exercise, or being physically active during chemotherapy, on long-term cognitive performance or self-reported cognition, except for the task reaction time, which favored the control group (β = -2.04, 95% confidence interval: -38.48; -2.38). We observed no significant association between self-reported higher physical activity levels during chemotherapy or at follow-up and better cognitive outcomes.ConclusionIn this pragmatic follow-up study, exercising and being overall more physically active during or after adjuvant chemotherapy for breast cancer was not associated with better tested or self-reported cognitive functioning, on average, 8.5 years after treatment. Future prospective studies are needed to document the complex relationship between exercise and CRCI in cancer survivors.

PHYSICAL ACTIVITY AND SOCIAL COGNITIVE THEORY CORRELATES AMONG POSTOPERATIVE PERSONS WITH CROHN'S DISEASE: PRELIMINARY RESULTS FROM A CROSS-SECTIONAL ANALYSIS

Abstract INTRODUCTION There is increasing research and clinical interest in physical activity (PA) behavior among persons with Crohn's disease (CD), but little is known regarding PA and its correlates among postoperative persons with CD. This is important as most patients with CD will require surgery within 10 years of diagnosis which may drastically alter PA levels and its benefits for CD. As found in past studies with other patient populations (e.g., colorectal cancer survivors), understanding the cognitive and behavioral factors associated with PA engagement among postoperative adults with CD is useful for informing the development of PA behavior change interventions for this population. This cross-sectional study examined self-reported PA levels and its associations with social cognitive theory (SCT) variables among postoperative persons with CD. METHODS Participants included 30 persons with CD who completed an online survey between November 2022 and June 2023. Of those participants, 18 reported a history of CD-related surgery. The survey assessed demographic and clinical characteristics, disease activity (Harvey-Bradshaw Index), leisure time exercise (Godin Leisure-Time Exercise Questionnaire and International Physical Activity Questionnaire), and related SCT variables (exercise self-efficacy, social support, outcome expectations, goal setting, and planning). Analyses included independent sample t-tests and non-parametric bivariate correlations (rs) for comparing PA levels and SCT survey scores among participants with and without a history of surgery. RESULTS There were differences in PA and SCT variables based on surgical history. Postoperative participants engaged in significantly more PA (t = 2.17, p = 0.04) and reported greater outcome expectations (t = 2.45, p = 0.02) and goal setting (t = 2.22, p = 0.04) scores compared with CD participants without a history of surgery. Among postoperative participants, only exercise goal setting was significantly correlated with PA (rs = .53, p = 0.03) such that postoperative participants with greater exercise goal setting behaviors reported higher levels of PA. None of the SCT variables were significantly associated with PA in the sample of participants without a history of surgery. CONCLUSIONS This study yielded novel findings regarding PA behavior and its SCT correlates in a small sample of postoperative persons with CD. The results suggest the need for further research into exercise goal setting as a potential target of behavior change interventions for increasing PA among postoperative persons with CD.

Relationships between pre-service teachers’ self-reported physical activity and their perceptions of physical education in early childhood teacher education

This study aimed to explore the relationships between Finnish early childhood pre-service teachers’ ( N = 274; aged 20–49; 92% female) self-reported physical activity (PA) and perceptions of their own enjoyment of schooltime physical education (PE), self-evaluation of the content of their current PE studies, perceived importance of PE, and perceived competencies in PE. The one-way analysis of variance revealed that pre-service teachers with higher self-reported levels of PA reported higher scores for perceived importance of PE in supporting a child's physical functionality ( p = 0.004), and perceived competencies to support a child's PA ( p = 0.017) and teach PE ( p = 0.023). Results of independent sample t-tests indicated that pre-service teachers meeting daily PA guidelines reported higher scores for enjoyment of schooltime PE ( p = 0.001) and perceived competence to teach PE ( p = 0.001). Findings highlighted that pre-service teachers’ self-reported PA was positively related to their perceptions of PE, supporting the recommendation within early childhood teacher education to encourage pre-service teachers to engage in PA.

Correlates of life course physical activity in participants of the Baltimore longitudinal study of aging.

Physical activity is consistently associated with better health and longer life spans. However, the extent to which length and intensity of exercise across the life course impact health outcomes relative to current activity is undefined. Participants of the Baltimore Longitudinal Study of Aging were asked to categorize their level of physical activity in each decade of life from adolescence to the current decade. In linear mixed effects models, self-reported past levels of physical activity were significantly associated with activity assessed at study visits in the corresponding decade of life either by questionnaire or accelerometry. A pattern of life course physical activity (LCPA) derived by ranking participants on reported activity intensity across multiple decades was consistent with the trajectories of activity estimated from standard physical activity questionnaires assessed at prior study visits. In multivariable linear regression models LCPA was associated with clinical characteristics, measures of body composition and indicators of physical performance independent of current physical activity. After adjustment for minutes of high intensity exercise, LCPA remained significantly associated with peak VO2, fasting glucose, thigh muscle area and density, abdominal subcutaneous fat, usual gait speed, lower extremity performance, and multimorbidity (all p < 0.01) at the index visit. The observed associations suggest that an estimate of physical activity across decades provides complementary information to information on current activity and reemphasizes the importance of consistently engaging in physical activity over the life course.

MULTIPLE MEASURES OF FITNESS ASSOCIATION WITH MUSCLE MRNA SPLICING VARIANTS IN THE GESTALT STUDY

Abstract Regular physical activity has been associated with higher skeletal muscle mass and strength as well as better mitochondrial function. Previous studies in master octogenarian athletes found a higher content of mitochondrial- and reduced spliceosome proteins compared to non-athlete age/sex-matched controls. These findings suggest that higher mitochondrial function is associated with down-regulation of the spliceosome. In this study we aimed to detect mitochondrial respiration associations with expression of specific genes and differentially spliced isoforms. We performed RNA-seq from vastus lateralis skeletal muscle biopsies in 82 male/female participants in the GESTALT study (Genetic and Epigenetic Signatures of Translational Aging Laboratory Testing). We correlated gene expression, transcript usage and splicing events with I) self-reported level of physical activity in daily life, II) peak oxygen consumption assessed during an incremental treadmill stress testing, III) muscle oxidative capacity assessed by p31 MR Spectroscopy and IV) mitochondrial-respirometry assessed on permeabilized muscle fibers, using regression models adjusted for age, gender, and batch. Except for IV), all three mitochondrial measures positively correlated with each other, and were downregulated along the Aging axis. We detected 423, 219, 178 and 226 differentially expressed genes (p-value&amp;lt;0.01), respectively for the 4 mitochondrial fitness measures. Gene-set-enrichment analysis (GSEA) detected up-top TCA cycle and mitochondrial respiration kPCr and mito-respirometry detected the highest number of AS events (448 and 412). Dissimilarities among transcriptomic profile associated to these four bioenergetic outcomes provide insight into the biological mechanisms that connect them to mitochondrial function and suggest that mitochondrial function is not the only correlate of movement behaviors.

WHOLE HEALTH(Y) AGING WITH GEROFIT: THE DEVELOPMENT OF A PILOT WELLNESS PROGRAM FOR OLDER VETERANS

Abstract The Veterans Health Administration (VHA) services over 9 million Veterans; approximately half are older than 65 years of age. Veterans are at a higher risk of comorbidities, including obesity and related chronic diseases, which contributes to higher health care costs, mobility disability, poor quality of life and even death. Gerofit is a VA Best Practice and Whole Health clinical exercise program for Veterans &amp;gt;65yrs that has positively impacted physical functioning, mental health symptoms, medication burden and 10-year mortality. This project describes the development of a comprehensive wellness and health promotion program incorporated into Gerofit, called Whole Healthy Aging Gerofit (WHAG). This novel program implemented wellness components to supplement the Gerofit in-person or virtual exercise options, including health education seminars, mindfulness classes, yoga classes, nutrition education classes, produce pick up service, and the Companion Dog Fostering program. WHAG deliverables included class attendance, individual Personal Health Inventories, observed physical function, self-reported physical activity levels, diet quality, perceived mental health, and Veteran satisfaction. The average Gerofit participant is approximately 73 years old, with obesity and multiple comorbid conditions (n=16), takes 10 medications, and is functionally impaired as assessed by gait speed (1.04 m/s). Programs that target healthy aging are needed to ensure the health of the population as it ages. This pilot program, WHAG, is one example of a comprehensive, patient centered wellness program that supports participants in setting their own goals and definitions of wellness to promote healthy aging.

Tonic cuff pressure pain sensitivity in chronic pain patients and its relation to self-reported physical activity.

Physical inactivity is a global health concern and a significant problem among chronic pain patients. They often experience pain flare-ups when they try to increase their physical activity level. Most research on the relationship between pain sensitivity and physical activity has been on healthy participants. Data on chronic pain patients are lacking. Using cuff pressure algometry, this study investigated tonic cuff pressure pain sensitivity and its associations to self-reported physical activity and other patient-reported outcomes in chronic pain patients. Chronic pain patients (n=78) were compared to healthy controls (n=98). Multivariate data analysis was used to investigate the associations between tonic cuff pressure pain sensitivity, physical activity, and other patient-reported outcome measures. The three most important variables for group discrimination were perceived health status (EQVAS: p(corr)=-0.85, i.e., lower in patients), depression (HADS-D: p(corr)=0.81, i.e., higher in patients), and the tonic cuff pressure pain sensitivity variable maximum pain intensity (VAS-peak-arm: p(corr)=0.75, i.e., higher in patients). In patients, the most important predictors for high VAS-peak-arm were female sex (p(corr)=-0.75), higher number of painful regions (p(corr)=0.72), higher pain intensity (p(corr)=0.55), followed by lower level of self-reported physical activity (p(corr)=-0.39). VAS-peak-arm in patients correlated negatively with self-reported physical activity (rho=-0.28, p=0.018). Physical activity may be the most important patient-changeable variable correlating to pain sensitivity. This study highlights the importance of more research to further understand how increased physical activity may decrease pain sensitivity in chronic pain patients.

Physical activity, physical frailty and depressive symptoms among Chinese male and female older adults: do different indicators make a difference?

Older adults become more inactive and frailer with aging. Physical status is closely linked to mental health, but it is unclear which physical indicator is more strongly associated with depressive symptoms in older adults. The present study aimed to compare relationships between self-reported physical activity, physical frailty (muscle mass, muscle strength, and gait ability) and depressive symptoms in community male and female older adults. A total of 1,180 adults aged 60 years and older were recruited to participate in this study from a Chinese community receiving annual check-up service from September 2018 to May 2019. Physical activity was assessed by the International Physical Activity Questionnaire (IPAQ). The Bio-electrical Impedance Analyzer was used to determine the muscle mass. As the indicators of muscle function, grip strength and gait ability were assessed by the dynamometer and Timed Up and Go Test (TUGT), respectively. The 15-item version of Geriatric Depression Scale (GDS-15) was used to examine depressive symptoms. Demographic variables, health status and sleep quality were collected using questionnaire. 11.8% men and 11.9% women reported depressive symptoms. Logistic regression showed that depressive symptoms was associated with low grip strength (OR = 2.42, 95% CI: 1.04-5.63), slow gait ability (OR = 3.60, 95% CI: 1.28-10.13) in older males, and associated with low level of self-reported physical activity (OR = 3.85, 95% CI: 2.00-7.42) in older females. No significant association was found between muscle mass and depressive symptoms. There were gender differences in the relationship between physical activity, physical frailty, and depressive symptoms. Grip strength and gait ability may be a better indicator of frailty for predicting depressive symptoms in older men while physical activity may be useful in predicting depressive symptoms in older women.

Self-Reported Physical Inactivity and Mood Disturbances in End-Stage Kidney Disease (ESKD) Patients on Chronic Dialysis Treatment.

Physical inactivity and mood disturbances are key issues in individuals with end-stage kidney disease (ESKD) and may lead to poor clinical outcomes. We performed a pilot, observational study to explore the possible relationships between the self-reported level of physical activity (IPAQ) and the severity of mood disturbances (BDI score) in a cohort of 58 ESKD patients undergoing chronic hemodialysis (HD; n = 30) or peritoneal dialysis (PD; n = 28). Overall, ESKD patients were severely inactive (median METs: 590 [460-1850]) and the intensity of overall and walking physical activity was mostly low to moderate. HD individuals appeared less active than PD (METs 550 [250-1600] vs. 1080 [750-1730]; p = 0.003) and were also less prone to walking (METs 180 ± 90 vs. 320 ± 100; p = 0.01), while a barely statistical difference was noticed for the time spent sitting. ESKD individuals displayed a median BDI score of 17 [12-21], which indicated, on average, the presence of borderline depression, which was apparently more evident among HD individuals. A strong, inverse correlation was found between self-reported METs and BDI scores (R = -0.78; p < 0.0001), while such scores paralleled the time spent sitting during a weekday (R = 0.45; p = 0.0004) and a weekend day (R = 0.40; p = 0.002). In ESKD patients on chronic dialysis, physical inactivity and mood disturbances might be significantly inter-connected, thereby amplifying their relative impact on quality of life, dysautonomia and long-term outcomes. Future studies on larger populations are recommended to confirm these preliminary observations. Promoting strategies to improve fitness, along with greater attention to physiological aspects, should be incorporated into the clinical management of ESKD patients.

Physical Activity, Depression and Quality of Life in COPD - Results from the CLARA II Study.

Symptoms of depression, pain and limitations in physical activity may affect quality of life in COPD patients independent from their respiratory burden. We aimed to analyze the associations of these factors in outpatients with COPD in Austria in a stable phase of disease. We conducted a national, cross-sectional study among patients with COPD. For depression, the Patient Health Questionnaire-9 (PHQ-9) and for respiratory symptoms the St. George's Respiratory Questionnaire for COPD patients (SGRQ-C) were used along with 10-point scales for physical activity and pain. After exclusion of 211 patients due to non-obstructive spirometry or missing data, 630 patients (62.5% men; mean age 66.8±8.6 (SD) years; mean FEV1%pred. 54.3 ± 16.5 (SD)) were analyzed. Of these, 47% reported one or more exacerbations in the previous year, 10.4% with hospitalization. A negative depression score was found in 54% and a score suggesting severe depression (PHQ-9 score≥15) in 4.7%. In a multivariate linear regression model, self-reported pain, dyspnea, and number of exacerbations were predictors for higher PHQ-9-scores. A negative pain score was found in 43.8%, and a score suggesting severe pain in 2.9% (8-10 points of 10-point scale). Patients reporting severe pain were more often female, had more exacerbations, and reported more respiratory and depressive symptoms, a lower quality of life, and less physical activity. About 46% of patients rated their physical activity as severely impaired. These patients were significantly older, had more exacerbations, concomitant heart disease, a higher pain and depression score, and a lower quality of life (SGRQ-C - total score and all subscores). In Austria, nearly half of stable COPD outpatients reported symptoms of depression, which were associated with lower levels of self-reported physical activity, more pain, and respiratory symptoms. The associations were particularly strong for depression with SGRQ-C.

Nothing in Excess: Physical Activity, Health, and Life World in Senegalese Fulani Male Pastoralists, a Mixed Method Approach

Objectives: The goal of this study was to evaluate the application of the short form of the International Physical Activity Questionnaire Survey (IPAQ-SF) in the rural Senegalese Fulani pastoralist population by combining quantitative and qualitative methods. Design and participants: For the quantitative method, 101 men completed the IPAQ-SF questionnaire measuring moderate, vigorous, and walking physical activity. Self-rated health, BMI, and sociodemographic variables were also collected. With regard to the qualitative methods, a total of 22 participants were recruited and interviewed. Four themes were addressed, including (i) physical activity (PA) and its definition, description, related experiences, and representations of social actors; (ii) PA and health; (iii) PA and sport; and (iv) the body and Fulani world of life (i.e., Pulaagu/Ndimaagu). Results: Sahelian herders have a high level of self-reported PA and a low amount of daily sitting time. The measure of PA as proposed by the IPAQ-SF is not adapted to the Senegalese Ferlo pastoralists, mainly because this scale gives too much importance to leisure-time PA, perceived as unproductive energy expenditure, which is factually and symbolically antinomic to the Fulani lifeworld. Thus, neither intense nor moderate PA is related to self-rated health. However, sedentary lifestyles are linked to self-rated health and, therefore, to mortality and morbidity in Fulani pastoralists. Finally, walking, which is the dominant PA during transhumance and herd surveillance, is related to BMI. It therefore represents a protective factor against the occurrence of overweight and associated chronic non-communicable diseases. Conclusion: The mixed method approach developed in this study has shown that the IPAQ-SF is not a valid measure of PA in the population of Fulani male herders from the Ferlo region, given that unproductive energy expenditure is incompatible with the Fulani way of life, which condemns excess and immoderation.
