Factors Associated with Fatigue among Men Aged 45 and Older: A Cross-Sectional Study

The Spider: a visual, multisystemic symptom impact questionnaire for people with hypermobility-related disorders-validation in adults

INTRODUCTION

Hypermobility spectrum disorders (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS) are often accompanied by varied and complex multisystemic comorbid symptoms/conditions. The Spider questionnaire was developed to evaluate the presence and impact of eight common multisystemic comorbidities. Thirty-one questions across eight symptom domains assess neuromusculoskeletal, pain, fatigue, cardiac dysautonomia, urogenital, gastrointestinal, anxiety, and depression symptoms. This study aimed to evaluate the Spider's construct validity in adults.

METHOD

A cross-sectional observational study was conducted over four stages. Three international patient charities aided recruitment of participants through social media and website advertisements. Adults aged 18 to 65 years, with and without HSD/hEDS, were invited to participate. Validated, frequently used comparator questionnaires were used to establish convergent validity of Spider symptom domains. A control group was recruited for known-group validity analysis. Participants answered each Spider domain and the corresponding comparator questionnaire via surveys hosted by REDCap. Anonymous data were analysed using SPSS. Convergent validity was assessed through Spearman's correlational analysis and known-group validity through Mann-Whitney U analysis.

RESULTS

A total of 11,151 participants were recruited across the four stages. Statistically significant, moderate-to-strong correlations were found between all Spider domains and their comparators (p < 0.001, r = 0.63 to 0.80). Known-group validity analysis showed statistically significant differences (p < 0.001) between the hypermobile and control groups in all eight domains.

CONCLUSIONS

Convergent and known-group validity of the Spider was established with adults. These results suggest the Spider can measure the presence and impact of multisystemic comorbid symptoms/conditions in adults with HSD/hEDS, providing a tool which guides multidisciplinary management. Key Points • The Spider questionnaire is a novel tool assessing the presence and impact of the multisystemic comorbid symptoms/conditions associated with HSD/hEDS. • Convergent and known-group validity of the Spider questionnaire was established in adults aged 18 to 65. • This tool provides a quick and easy method to visualise the symptom profile of those with HSD/hEDS to guide symptom management.

Physical and psychological job demands and fatigue experience among offshore workers

Offshore operations are generally challenging and hazardous, and the workers are exposed to conditions that may lead to fatigue. A cross-sectional study evaluated physical and psychological job demands and their associations with fatigue among offshore workers. The offshore workers (n = 251) completed a questionnaire including demographic/job details, Multidimensional Fatigue Inventory (MFI‒20), and Job Content Questionnaire (JCQ). Data were analysed using linear regression modelling. Results indicated that the physical (particularly performing repetitive motions and applying pressure with hands and wrists) and psychological (e.g., intense task concentration and fast working) job demands were relatively high. The total mean (SD) fatigue score (MFI‒20) was 56.3 (13.9). Individual factors (Body Mass Index ‒ BMI), physical job demands (awkward working postures, frequent moving/lifting heavy objects and doing lots of physical efforts) and psychological job demands (task interruptions by other people and doing an excessive amount of work) were the main variables associated with different dimensions of fatigue in the multivariate models. While physical fatigue was only associated with the physical job demands, both physical and psychological job demands were significantly associated with mental fatigue in the multivariate context. The findings have possible implications for job design and implementation of intervention programmes to promote health and performance of the employees.

The impact of fatigue on mortality of patients with non-alcoholic fatty liver disease: Data from National Health and nutrition examination survey 2005-2010 and 2017-2018

OBJECTIVE

Fatigue among patients with NAFLD may negatively impact their health-related quality of life and clinical outcomes (mortality). We determined fatigue prevalence and its association with all-cause mortality among patients with NAFLD.

DESIGN

NHANES 2005-2010 and 2017-2018 data were used with linked mortality data. NAFLD was defined by fatty liver index for NHANES 2005-2010 and by transient elastography for NHANES 2017-2018. Fatigue was assessed by Patient Health Questionnaire.

RESULTS

NHANES 2005-2010 cohort (n = 5429, mean age 47.1 years, 49.7% male, 69.9% white), 37.6% had NAFLD. Compared to non-NAFLD controls, fatigue was more common in NAFLD (8.35% vs 6.0%, p = .002). Among NHANES 2017-2018 cohort (n = 3830, mean age 48.3 years, 48.6% male, 62.3% white), 36.9% had NAFLD. Compared to non-NAFLD controls, fatigue was more common among NAFLD (8.7% vs 6.2%). NAFLD had more sleep disturbance (34.0% vs 26.7%), cardiovascular disease (CVD) (10.7% vs. 6.3%), significant hepatic fibrosis (liver stiffness>8.0 kPa, 17.9% vs 3.5%) and advanced hepatic fibrosis (>13.1 kPa, 5.4% vs 0.9%; all p < .003). The presence of depression (OR: 11.52, 95% CI: 4.45-29.80, p < .0001), CVD (OR: 3.41, 95% CI: 1.02-11.34, p = .0462) and sleep disturbance (OR: 2.00, 95% CI: 1.00-3.98, p = .0491) was independently associated with fatigue; good sleep quality (OR: 0.58, 95% CI: 0.35-0.96, p = .0366) had an inverse association. By multivariable Cox model, NAFLD adults with fatigue experienced 2.3-fold higher mortality than NAFLD without fatigue (HR: 2.31, 95% CI: 1.37-3.89, p = .002).

CONCLUSIONS

Fatigue among those with NAFLD is associated with increased risk for mortality and is mainly driven by depression, sleep disturbance and CVD. These findings have important clinical implications.

Physical and mental fatigue in people with non-communicable chronic diseases

BACKGROUND

Fatigue is frequently reported in people with a non-communicable chronic disease. More insight in the nature of this symptom may enhance targeted treatment of fatigue. In this study, we aimed to gain more insight in the prevalence of different types of fatigue and in current prescribed treatment strategies to reduce fatigue in non-communicable chronic diseases.

METHODS

People with non-communicable chronic diseases were contacted via public, non-profit, disease-specific health funds and patient associations and invited to complete a web-based survey. The survey included a general question about the experience ("Do you now or have you ever had complaints of fatigue?") and nature of fatigue (physically/mentally/combination), the Checklist Individual Strength-subscale subjective fatigue (CIS-Fatigue; 8-56 points), self-constructed questions for the distinction between physical and mental fatigue (both 3-21 points) and questions on prescribed treatments for fatigue.

RESULTS

In total, 4199 participants (77% females) completed the online survey. 3945 participants (94.0%) reported experiencing fatigue, of which 64.4% reported a combination of both physical and mental fatigue. Median CIS-Fatigue score was 41 (32-48) points, with 68% of the participants reporting severe fatigue (≥36 points). Median scores for physical and mental fatigue were 15 (11-18) and 12 (8-16) points, respectively. In 55% of the participants, fatigue was only occasionally or never discussed with the healthcare professional, and only 23% of the participants were prescribed a treatment for fatigue. Participants often reported no effect or even an increase in fatigue after treatment.

CONCLUSIONS

Findings indicate that both physical and mental fatigue are often experienced simultaneously in people with non-communicable chronic diseases, but can also occur separately. Fatigue is often only occasionally or never discussed, let alone treated, highlighting the need to raise awareness among healthcare professionals. Future studies are needed to gain more insight in underlying factors of fatigue in non-communicable chronic diseases, its impact on daily life and development and evaluation of targeted treatment strategies.Key messages:Both physical and mental fatigue are frequently present in people with non-communicable chronic diseases.Fatigue is often only occasionally or never discussed during consultation with the physician, highlighting the need to raise awareness among healthcare professionals for adequate screening and evaluating of fatigue in people with non-communicable chronic diseases.Only less than a quarter of the people with non-communicable chronic diseases who reported to experience fatigue were prescribed a treatment for fatigue, which was often experienced as ineffective.

Chronic Illness and Fatigue in Older Individuals: A Systematic Review

BACKGROUND

Fatigue is a symptom experienced by 40%-74% of older individuals in the United States. Despite its significance, clinicians face challenges helping individuals to manage or reduce fatigue levels. Some management issues are attributable to the ambiguity around the risk factors, consequences, and the effect of fatigue management strategies.

METHODS

A literature review was conducted using four databases to identify themes in relation to risk factors, consequences, and management strategies from research studies about fatigue in older individuals with chronic diseases.

RESULTS

Findings on fatigue risk factors, such as age, body mass index, and marital status, were contradictory. There was a positive association between fatigue and comorbidities, depression, and anxiety and a negative relationship between fatigue and physical activity, sleep, educational status, and socioeconomic status. Fatigue was perceived as a state of "feebleness" and negatively impacted individuals' quality of life. Consequences of fatigue included tiredness, sleepiness, depression, anxiety, worse sense of purpose in life, poor self-care, and an increased β-amyloid load. Predictors of worse fatigue consequences included functional health, symptom burden, subjective health, and self-acceptance. Fatigue management strategies included physical activity, rest, sleep, maintaining normal hemoglobin levels, and acetyl-l-carnitine supplementation.

CONCLUSION

This systematic review is of value to older individuals with chronic illnesses, researchers, and clinicians who strive to improve the quality of life of individuals experiencing fatigue. To prevent undesirable consequences of fatigue, older individuals should be screened for the discussed modifiable risk factors of fatigue. The inconsistencies in the studies reviewed can guide researchers to potential research areas that require further inquiry and exploration to ground future practice on best scientific evidence.

Symptom experience of adverse drug reaction among male and female patients with newly diagnosed pulmonary tuberculosis in Thailand

Background

Patients with newly diagnosed pulmonary tuberculosis often suffer from adverse drug reaction symptoms, which leads to the automatic discontinuation of anti-tuberculosis drugs. Thus, understanding symptom experience of adverse drug reactions is necessary.

Objective

This study aimed to examine differences in symptoms experienced in four dimensions: presence, frequency, severity, and distress of adverse drug reactions, between male and female patients.

Methods

This was a quantitative survey with a cross-sectional design, with data collected between January and April 2020. A total of 394 patients with newly diagnosed pulmonary tuberculosis was selected through a purposive sampling technique. The symptom experiences of adverse drug reactions were measured using a validated instrument. Data were analyzed using mean, standard deviation, and independent t-test.

Results

The most commonly reported symptom was itchiness (24.1% in males and 34.9% in females). Vomiting occurred as the most frequent symptom among males (x̄ ± SD = 2.73 ± .88), and fatigue was found to be the most severe and distressing symptom across male patients (x̄ ± SD = 2.50 ± 1.61 and 2.06 ± 1.30, respectively). In contrast, yellowing of the eyes and skin was most frequent and severe among females (x̄ ± SD = 3.17 ± .75 and 3.83 ± 1.47, respectively). In addition, flu-like symptoms were evaluated as the most distressing symptom for female patients (x̄ ± SD = 2.80 ± 1.09). The symptom burdens of the females ranged significantly and reached higher than those of the male patients at a p-value of .05 (t = 3.33).

Conclusion

Females taking anti-tuberculosis drugs should be carefully monitored to deal with adverse drug reaction symptoms. This finding would help to decrease the severity of disease and improve their quality of life.

Relationship between work fatigue and manual dexterity in dental professionals: observational study

BACKGROUND

Neuro-muscular fatigue (ANM) in the upper limbs can cause impaired coordination and dexterity. The main purpose of the study was to investigate whether ANM induced by a working day produced a reduction in digital dexterity in a population of dental health workers (OSD). Secondary objective was to investigate whether there were relationships between any reductions in dexterity and independent socio-demographic variables (gender, age and profession).

METHODS

A cohort of OSD was assessed before and at the end of a working day of at least 7 hours using the Functional Dexterity Test (FDT). The effects of ANM (time), of the tested limb (dominance), and of their interaction on dexterity were investigated using two-way ANOVA. A multiple linear regression model was applied to explore the relationship between dexterity performance and independent variables.

RESULTS

A total of 50 OSDs were included. The net time of the FDT at the end of the day was always higher than in the morning. The ANOVA showed a significant difference for time (p <0.001) and side (p <0.001), but an effect from the interaction between the two factors was not identified (p = 0.428). The worsening of manual dexterity appears to be weakly correlated with age on both sides, and with the profession in the dominant limb.

CONCLUSION

The ANM appears to have negatively affected the dexterity of both hands in the sample examined. The results of this study may be useful for planning the OSD's work agenda more carefully.

Fatigue-Related Factors for Community-Dwelling Older Adults with Diabetes: A Theory-Guided Multi-Dimensional Approach Using the Dynamic Biopsychosocial Model

Older adults with diabetes appear more susceptible to fatigue compared to younger adults with diabetes or healthy older adults, since aging and diabetes independently and synergistically influence fatigue. Few studies have investigated fatigue in older adults with diabetes using a multidimensional approach. This study explored the influences of physical, psychological, interpersonal, and contextual factors on diabetes fatigue using a dynamic biopsychosocial model. Face-to-face surveys were administered to community-dwelling older adults with diabetes and included variables across four domains (i.e., physical, psychological, interpersonal, and contextual factors). Univariate analyses and multiple linear regression were used. The mean fatigue score was 3.94 (standard deviation (SD) = 1.81) out of 7, and the prevalence of fatigue was 48.8%. Significant differences in fatigue severity by psychological, interpersonal, and contextual factors were found. Comorbidity and psychological factors were significant predictors of fatigue in the model, explaining 31.9% of the variance. As nearly half the sample experienced moderate or severe fatigue, which was significantly influenced by both comorbidity and psychological factors, including depression, sleep quality, and diet-related psychological characteristics, assessing patients' psychological status may be important. Awareness of fatigue could be incorporated into dietary interventions for older adults with diabetes.

Are BMI and inflammatory markers independently associated with physical fatigability in old age?

Background

Obesity and chronic low-grade inflammation have both been implicated in the onset of physical fatigue. However, few studies have investigated the independence of these associations in older community-dwelling populations. We therefore aimed to investigate the associations of body mass index (BMI) and inflammatory markers at age 60–64 with perceived physical fatigability at age 68 and to assess whether any such associations were independent of each other and potential confounding factors. A secondary aim was to investigate whether any association with BMI extended back into earlier adulthood.

Methods

Participants of the MRC National Survey of Health and Development (N = 1580) had BMI and levels of interleukin-6 (IL-6) and C-reactive protein (CRP) measured during clinical assessments at age 60–64. These were related to self-perceived physical fatigability assessed at age 68 using the Pittsburgh Fatigability Scale (PFS) (total score:0 (no physical fatigue)–50 (extreme physical fatigue)).

Resuts

Women had higher mean PFS scores than men (mean (SD): 16.0 (9.1) vs 13.2 (8.9), p < 0.01). In sex-adjusted models, BMI, CRP and IL-6 were each associated with PFS scores. When all three factors were included in the same model, BMI and IL-6 remained associated with PFS scores whereas CRP did not. After adjustment for a range of potential confounders, associations of BMI and IL-6 with PFS scores were still evident; fully adjusted differences in mean PFS score = 3.41 (95% CI: 0.59, 6.24) and 1.65 (0.46, 2.84) for underweight and obese participants when compared with normal weight and, 2.78 (1.65, 3.91) when comparing those with an IL-6 of 2.51–8.49 pg/mL with levels <1.50.

Conclusions

BMI and inflammation may both be suitable targets for intervention to reduce the burden of physical fatigability in later life. Further, interventions that target both obesity and elevated levels of IL-6 are likely to be more effective than those focusing on only one.

A correlation between sickness or injury within two weeks, chronic diseases and fatigue among adults aged 18-45 years

To investigate the prevalence of fatigue, the relationship between sickness or injury within two weeks, chronic diseases and fatigue among adults aged 18-45 years. Thousand five hundred and seventy nine individuals were included in this cross-sectional study. The Chalder Fatigue Scale (CFS) was used to assess fatigue defined as CFS score ≥4. The prevalence of fatigue was 25% in this study. Our results showed that only sickness or injury within two weeks (odds ratio [OR]: 2.440) and chronic diseases (OR: 1.727) were significantly related to fatigue. Moreover, their ORs for fatigue remained the same in all models (binary logistic regression models with adjusting for demographic and health-related characteristics one by one). In conclusion, fatigue was prevalent among adults aged 18-45 years. Sickness or injury within two weeks and chronic diseases were the risk factors for fatigue independent of demographic and health-related characteristics.

High fatigue and its associations with health and work related factors among female medical personnel at 54 hospitals in Zhuhai, China

The present study aimed to investigate the prevalence of fatigue and determine factors associated with fatigue in female medical personnel. Based on a cross-sectional study, a total of 1608 female medical personnel at 54 hospitals in Zhuhai, China were recruited by a multistage stratified cluster sampling method. The Symptoms Checklist-90-Revised and Chalder Fatigue Scale were used to assess psychiatric symptoms and fatigue, respectively. Data regarding demographic, health, and work related variables were also collected. Multivariate logistic regression model was constructed to determine the influencing factors of fatigue. Approximately 83% of participants had experienced fatigue in the past week. The risk of fatigue was higher in aged 30-39 years old than older or younger participants; Longer sleeping time predicted a lower prevalence of fatigue (OR = .35), while tense physician-patient relationship predicted a higher prevalence of fatigue (OR = 1.77). Depression (OR = 1.76) and anxiety (OR = 1.96) were found related to fatigue. Additionally, fatigue was associated with marital status, occupation, health related factors (exercise, regular diet, and health status), and work related factors (hospital rank and turnover intention). These study findings might facilitate development and implementation of targeted interventions and preventive measures.

Excessive daytime sleepiness and fatigue may indicate accelerated brain aging in cognitively normal late middle-aged and older adults

Excessive daytime sleepiness (EDS) and fatigue increases with age. The aim of this study was to investigate the association between EDS and fatigue with cortical thickness and hippocampal volume in cognitively normal, late middle-aged and older adults. We performed a cross-sectional observational study of 1374 cognitively-normal subjects aged 50 years and older who had a structural MRI. Regional cortical thickness and hippocampal volume were measured. Multiple linear regression models were fit to explore associations between EDS and fatigue and structural MRI measures in different brain regions, adjusting for multiple covariates. EDS was defined as Epworth Sleepiness Scale ≥10. Fatigue severity was assessed with the Beck Depression Inventory-2. 208 participants had EDS, 27 had significant fatigue, and 11 had both. Participants with EDS or fatigue had significantly lower cognitive scores, more disturbed sleep, and medical comorbidities. The presence of EDS was associated with both global and regional atrophy, whereas fatigue was more associated with frontal and temporal changes. Cortical thinning predicted by EDS and fatigue was maximal in the temporal region with average reduction of 34.2 μm (95% CI, -54.1, -14.3; P = 0.001) and 90.2 μm (95% CI, -142.1, -38.2; P = 0.001), respectively. Fatigue was also associated with hippocampal volume reduction of -374.2 mm³ (95% CI, -670.8, -77.7; P = 0.013). Temporal cortical thinning predicted by presence of EDS and fatigue was equivalent to more than 3.5 and 9 additional years of aging, respectively. EDS and fatigue were associated with cortical thickness reduction primarily in regions with increased age-susceptibility, which may indicate accelerated brain aging.
