RESUMO

PURPOSE: Physical activity (PA) is beneficial but difficult to maintain during chemotherapy. This pilot RCT explored the feasibility of the MI-Walk intervention-an 8-week motivational enhancement therapy- and home-based brisk walking intervention-among gastrointestinal (GI) cancer survivors receiving chemotherapy. METHODS: Sixty stage II-IV GI cancer survivors were recruited from 5 sites at their second infusion visit. Participants were randomized to receive PA education alone or the MI-Walk intervention: motivational enhancement therapy consisting of 3 motivational interviewing and self-efficacy-enhancing counseling sessions, a Fitbit Charge 2, exercise diaries, telephone follow-up, scripted motivational email messages, and optional weekly walking groups. RESULTS: The enrollment and completion rates were 62% and 90%, respectively. The MI-Walk participants (n = 29; mean age = 56.79, SD = 11.72; 97% white; 79% male) reported a baseline moderate-vigorous PA duration of 250.93 (SD = 636.52) min/wk. The mean MI-Walk Intervention acceptability score was 50.32 (SD = 12.02) on a scale of 14-70. Mean Fitbit and counseling helpfulness scores on a 5-point scale were 3.67 (SD = 1.43) and 3.44 (SD = 1.36), respectively. Participants' Fitbit moderate-vigorous PA 8-week averages ranged from 0 to 716.88 min/wk; 64% of participants adhered to ≥127 min/wk. Several characteristics (e.g., age, comorbidity, PA level, employment status, BMI, education level, gender, symptoms) were associated with enrollment, attrition, and intervention acceptability and adherence (p < 0.05). CONCLUSION: Enrollment and retention were adequate. The Fitbit and counseling were the most helpful. Acceptability and adherence varied based on participant characteristics; therefore, intervention tailoring and further research among cancer survivors less physically active at baseline and most in need of complex exercise intervention are needed. CLINICALTRIALS: gov NCT03515356.

RESUMO

Older adults in assisted living facilities (ALF) are at risk for low physical activity (PA) and high sedentary behavior (SB), both of which place them at risk for negative health outcomes. The purpose of this scoping review was to synthesize evidence describing the volume of device-measured PA/SB, factors associated with PA/SB, and interventions designed to change PA/SB in older adults living in ALF. Twenty articles representing 15 unique studies were identified from eight electronic databases and grey literature. Residents in ALF spent 96-201 min/day in light PA (n = 2 studies), 1-9.74 min/day in moderate to vigorous PA (n = 2 studies), and 8.5-11.01 hr/day of SB during waking hours (n = 3 studies). Factors associated with PA included 16 personal factors (n = 6 articles), one social factor (n = 2 articles), and two environmental factors (n = 2 articles). Factors associated with SB included 14 personal factors (n = 4 articles) and one social factor (n = 1 article). No intervention successfully changed PA/SB.

RESUMO

BACKGROUND: Older adults are highly sedentary, and too much sedentary behavior (SB) is associated with negative health effects, but little is known about SB patterns and their associations with functional status. AIMS: To examine the association between objectively measured sedentary behavior time (SBT) and sedentary behavior fragmentation (SBF) and functional status in older adults using the National Health Aging Trends Study (NHATS) dataset, a nationally representative sample from 2021. METHODS: Data from NHATS were analyzed using weighted linear regressions to examine the association between objective measures of SBT (mean hours spent in SB/day during waking hours) and SBF, and six functional variables (difficulties with activities of daily living [ADL], short physical performance battery, hand grip strength, immediate word recall, delayed word recall, and mental health), accounting for sociodemographic, body mass index, and the number of chronic conditions. RESULTS: A total of 738 individuals from the NHATS were included. Higher SBT was associated with greater difficulties with ADL, poorer short physical performance battery and hand grip strength, lower scores in both immediate and delayed word recall, and poorer mental health. Higher SBF was associated with fewer difficulties with ADL, better short physical performance battery and hand grip strength, a higher score in immediate word recall, and better mental health. DISCUSSIONAND CONCLUSIONS: Greater fragmentation of SB was associated with better function, and increasing SBF may be a useful strategy for mitigating the effects of SB in older adults, but prospective research is needed to support this approach.

RESUMO

More than 100 symptoms have been reported for post-coronavirus disease 2019 (COVID-19) and this study aimed to organize self-reported symptoms by identifying symptom clusters. We used a cross-sectional survey with a convenience sample of 491 adults who reported experiencing prolonged symptoms of COVID. A list of 25 symptoms of post-COVID-19 was used to measure the symptoms, and exploratory factor analysis was undertaken to identify symptom clusters for people with symptoms lasting 5 to 8 weeks and 9 weeks or longer. Six symptom clusters were identified for each of the two groups, and five clusters were similar across both groups: respiratory, general viral, smell/taste, cognitive cardiac, and mental health. The >9-week group reported symptoms primarily from two factors: respiratory-muscular and mental health. Post-COVID-19 symptom clusters differ across timeframes. Symptom clusters were useful in establishing coherent patterns of multiple complex symptoms.

RESUMO

BACKGROUND: Increased sedentary behavior (SB), especially in prolonged bouts, is associated with adverse health outcomes, but little is known about patterns of SB in people with chronic obstructive pulmonary disease (COPD). OBJECTIVES: The purpose of this study was to describe SB and patterns of SB and to examine factors associated with prolonged bouts of SB in inactive community-dwelling adults with COPD. METHODS: This cross-sectional analysis used data from inactive adults with COPD who were enrolled in an exercise program but had not started exercising. Participants were ≥ 50 years old with a diagnosis of COPD, had a forced expiratory volume in one second < 80% predicted, and were inactive. Participants wore an activPAL device for seven days to measure their SB and completed surveys and physical measures. Data were analyzed with multiple regression. RESULTS: The sample included 160 participants with a mean age (± SD) of 69 ± 8, and a mean total sedentary time of 742 ± 150 min/day, with 254 ± 146 min/day in SB bouts ≥ 60 min. DURATION: Time spent in bouts of SB ≥ 60-min. was negatively associated with self-efficacy for overcoming barriers to light physical activity (P<0.05), balance (P<0.05), chair stand test (P<0.05), FEV1% predicted (P<0.05) and positively associated with BMI (P<0.001). CONCLUSIONS: Inactive people with COPD engage in extensive SB, much of it in prolonged bouts. Self-efficacy, balance, and lower body strength are modifiable variables associated with SB and potential targets for future interventions to reduce time in prolonged sedentary behavior.

RESUMO

BACKGROUND: Stigma experiences contribute to psychological distress and negatively affect healthcare-seeking behavior in people with chronic obstructive pulmonary disease (COPD). Most evidence comes from qualitative research, and no well-established measure of COPD-related stigma exists. Prior research yielded a preliminary measure of COPD-related stigma, but it required item reduction and validation. OBJECTIVES: The purpose of this study was to revise the preliminary measure, reduce the number of items, identify underlying constructs, and evaluate the reliability and validity of the shortened version. METHODS: A descriptive, cross-sectional study was conducted. Participants (N = 148; mean = 64 ± 7.27 years) completed the 51-item preliminary COPD-related Stigma Scale (COPDSS). Item-level analysis was conducted before running exploratory factor analysis (EFA). Reliability was assessed using Cronbach's alpha. Convergent validity and known-groups validity were evaluated. RESULTS: In the item-level analysis, eight items were deleted, leaving 43 items for factor analysis. A four-factor model with 24 items (α = 0.93) was derived from EFA: social stigma (α = 0.95), felt stigma (α = 0.95), anticipated stigma-oxygen (α = 0.80), and smoking-related stigma (α = 0.81). The 24-item COPDSS was significantly correlated with the 8-item Stigma Scale for Chronic Illness (r = 0.83), the Hospital Anxiety and Depression Scale (r = 0.57), and the PROMIS Physical Function (r = -0.48). The 24-item COPDSS discriminated between known groups based on age (p = .03), use of inhalers (p = .002) and use of supplemental oxygen (p < .001), and psychological distress levels (ps < .001). CONCLUSION: Findings support the reliability and validity of the 24-item COPDSS. This instrument can be used to understand underlying stigma processes in people with COPD.

RESUMO

Background: Understanding the self-management practices of persistent symptoms of SARS-Cov-2 (COVID-19) is critical given the misinformation that has been presented about this disease in the U.S. The purpose of this descriptive study is to assess the self-management of persistent symptoms of COVID-19 with commonly used and misused substances (i.e., alcohol, marijuana and commonly prescribed medications) among adults in the U.S. Methods: The data for this study comes from a cross-sectional survey of U.S. adults that was designed to broadly assess symptom burden, persistent symptom patterns, self-efficacy for symptom management and self-management strategies among people who experienced persistent/Long COVID. Multiple logistic regression analyses were used to assess how symptom length of COVID-19 was associated with the use of several substances to manage these persistent symptoms. Results: The analysis found that adults who had COVID-19 symptoms that persisted for 13 weeks or longer had higher rates of using alcohol (27.3%), marijuana (30.9%) and prescription tranquilizers (21.4%) to manage these symptoms when compared to their adult peers who had COVID-19 symptoms persist for only 4 weeks or less. For instance, the odds of indicating the use of marijuana (AOR = 4.21 95% CI = 1.68,10.5) to manage COVID-19 related symptoms was roughly four times higher for respondents who had COVID-19 symptoms persist for 13 weeks or longer when compared to respondents whose COVID-19 symptoms persisted for only 4 weeks or less. Conclusion: The findings suggest that screening of substance use disorders should be considered among healthcare providers who are treating adults who have persistent symptoms of COVID-19.

RESUMO

Purpose: Physical activity (PA) plays an important role in health outcomes for people with cancer, and pre-diagnosis PA influences PA behaviors after cancer treatment. Less is known about the PA of lung cancer patients, and the strong history of smoking could influence pre-diagnosis levels of PA and place them at risk for health problems. This study aimed to compare pre-diagnosis PA and its correlates in patients with lung cancer and other types of cancer (female breast, colorectal, and prostate cancer) and examine the relationship between pre-diagnosis PA and all-cause mortality. Methods: This study used data from the UK Biobank, which is a national cohort study with accelerometry data. We included 2662 participants and used adjusted linear regressions and survival analyses. Results: Male and female lung cancer groups spent a mean of 78 and 91 min/day in pre-diagnosis moderate to vigorous PA (MVPA), respectively; this is lower than the 3 other types of cancer (p < 0.001). Younger age and faster walking pace had a strong association with PA in all the four types of cancer (p < 0.01). Smoking status had a strong association with PA in the lung cancer group, while obesity had a strong association with PA in female breast, colorectal, and prostate cancer (p < 0.01). Higher levels of pre-diagnosis MVPA (≥1.5 h/day) were associated with a significantly lower all-cause mortality risk. Conclusions: The present study suggests that lung cancer patients are the most inactive population before diagnosis. The identified difference in correlates of PA suggest that cancer-specific approaches are needed in PA research and practices. This study also highlights the importance of high PA for individuals with high cancer risk.

RESUMO

Decreasing sedentary behavior and increasing light physical activity could promote the maintenance of functional abilities for older adults in assisted living (AL). The purpose of this qualitative study was to gather residents' recommendations about a proposed self-efficacy enhancing intervention to replace sedentary behavior with light physical activity. We interviewed 20 residents (mean age 83.1; 60% women). Topics included their current activities and thoughts about physical activity. We presented the intervention and asked questions to inform its modification. Data were analyzed with content and thematic analysis. Specific recommendations included shorter one-hour sessions and framing the intervention as increasing light physical activity rather than decreasing sedentary behavior. The thematic analysis identified multiple factors that could influence intervention implementation, including motivation to be active, safety concerns, ageist attitudes about physical activity, varying abilities of residents, social influences, and limited opportunities for physical activity. These results will inform physical activity intervention implementation for AL residents.

RESUMO

BACKGROUND: Sedentary behavior is a significant health risk. Emerging research suggests that mentally active sedentary behaviors (e.g., computer use and reading) are associated with better health than mentally passive sedentary behaviors (e.g., watching TV). However, these relationships are not well established in the literature, and little is known about the oldest old (age ≥ 80). AIMS: The aims of this study were to (1) identify distinct subgroups of oldest old adults based on six domains of sedentary behavior (watching TV, using a computer/tablet, talking to friends or family members, doing hobby or other activities, transportation, and resting/napping); and (2) compare health-related outcomes across identified subgroups, using the National Health and Aging Trends Study (NHATS) dataset. METHODS: Latent profile analysis was used to identify distinct profiles of sedentary behavior. Design-based linear and logistic regressions were used to examine associations between different profiles and health outcomes, accounting for socio-demographic characteristics. RESULTS: A total of 852 participants were included. We identified four profiles and named them based on total sedentary time (ST) and passive/active pattern: "Medium-passive", "High-passive", "Low", "High-mentally active". Compared to the "High-passive" group, "Low" group and "High-mentally active" group were associated with fewer difficulties with activities of daily living, fewer problems limiting activities and higher cognitive function. CONCLUSION: This study, with a national representative sample of the oldest old population, suggests that both total ST and sedentary behavior pattern matter when evaluating health outcomes of being sedentary. Interventions should encourage oldest old adults to reduce ST and especially target mentally passive ST.

RESUMO

Low physical activity (PA) and high sedentary behavior (SB) place residents in assisted living at risk for physical decline, but little is known about factors that influence PA/SB in this setting. In the current cross-sectional study, we described objectively measured PA/SB (activPAL™) and examined the relationships between PA/SB and use of an assistive walking device, depression, sleep disturbance, pain, fatigue, social isolation, and the tendency to make social comparisons. Fifty-four residents from eight assisted living facilities participated. Mean time spent in PA was 252.9 (SD = 134.3) minutes/day. Mean time spent in SB was 660.8 (SD = 181.4) minutes/day. Depression predicted PA (R2 = 0.16). Residents using an assistive device spent significantly more time in SB (p = 0.02). Fatigue correlated with time in longer bouts of SB (r = 0.19, p = 0.04). The tendency to make social comparisons correlated with SB (r = 0.22, p = 0.04). Findings show residents in assisted living are inactive and further research is needed to fully understand factors that influence PA/SB. [Research in Gerontological Nursing, 15(3), 117-123.].

RESUMO

PURPOSE: Perioperative exercise could improve health outcomes of surgical lung cancer patients, but less is known about their natural physical activity (PA) behavior before exercise interventions. This review aimed to synthesize evidence on PA, regarding the following: (1) proportion of patients meeting PA guidelines, (2) amount of PA, (3) PA trajectory following surgery, and (4) correlates of PA before or after surgery. METHODS: We conducted a systematic review using PubMed, CINHAL, Scopus, and SPORTDiscus (July 2021). Observational or experimental studies that measure PA of lung cancer patients before/after surgery were included. We assessed methodological quality using the NIH Quality Assessment Tools and extracted data using a standardized form. RESULTS: Seventeen studies (25 articles, N = 1737 participants) published between 2009 and 2021 were included. Fourteen studies had sample sizes less than 100. Thirteen studies were of fair quality and four studies were of good quality. Only 23-28% of patients met PA guideline (150 min/week moderate-vigorous PA) at 6 months-6 years after surgery. Patients took an average of 3822-10,603 daily steps before surgery and 3934-8863 steps at 1-3 months after surgery. Physical activity was lower at 1 day-3 months after surgery, compared with preoperative levels. Perioperative PA was positively associated with exercise capacity, quality of life and reduced postoperative complications. CONCLUSION: This review suggests that PA is low among surgical lung cancer patients, and it may not recover within 3 months following surgery. Physical activity has the potential to improve postoperative outcomes. However, the existing evidence is weak, and future larger longitudinal studies are needed.

RESUMO

BACKGROUND: To increase psychological well-being and physical activity (PA) behaviors, our pilot study used the social ecological model as the framework to design the 4Active intervention, focusing on multicomponent exercise group lessons at the interpersonal level and self exercise enhanced by activity trackers at the individual level. The purpose of this pilot study was to examine the effectiveness of the two-level 4Active intervention in improving psychological well-being and PA participation in older adults living in retirement communities. METHODS: Participants were 27 older adults with a mean age of 85.9 ± 9.3 years. Based on the two-arm, quasi-experimental study design, fourteen older adults (2 men, 12 women) living in one retirement community (RC) were assigned into the intervention group receiving the two-level 4Active intervention, whereas 13 older adults (1 man, 12 women) living in another RC were allocated to the active control group receiving group exercise intervention alone for eight weeks. One week before and after the interventions, the participants were pre-tested and post-tested in psychological well-being (i.e., life satisfaction, subjective happiness, positive affect, and negative affect) and weekly PA minutes (i.e., weekly walking, vigorous, moderate, and total PA minutes). The data were analyzed be means of descriptive statistics, independent sample t-tests, and ANCOVA repeated measures. RESULTS: The results of ANCOVA repeated measures indicated that both groups maintained their slightly high or very high levels of life satisfaction, happiness, and positive affect over times. However, the two-level 4Active intervention group showed significant decreases in negative affect (F = 4.78, p = 0.04, η2 = 0.23) and significance increases in weekly moderate PA (F = 10.355, p = 0.004, η2 = 0.310) compared with the active control group over time. CONCLUSION: It is concluded that engaging in the two-level 4Active intervention including group-based multicomponent exercises and technology-enhanced self-exercises is more effective in decreasing negative affect and increasing weekly moderate PA METS-min in physically and cognitively frail older adults over time, compared with attending the group exercises alone.

RESUMO

BACKGROUND: Oxaliplatin-induced peripheral neuropathy (OIPN) is prevalent among gastrointestinal cancer survivors and often impairs quality of life (QOL). OBJECTIVE: This pilot randomized controlled trial aimed to explore the effect of an 8-week home-based brisk walking (the "MI-Walk") intervention on (1) OIPN severity and (2) QOL at 8 weeks, compared with physical activity (PA) education alone in oxaliplatin-receiving adults with gastrointestinal cancer. INTERVENTIONS/METHODS: Participants (N = 57) recruited from 5 infusion sites received PA education at their second oxaliplatin visit, followed by phone assessments of adverse events over 8 weeks. Half (n = 29) received additional MI-Walk intervention motivational supports (eg, a Fitbit Charge 2 and motivational enhancement therapy sessions). Self-reported OIPN, QOL, and PA were measured before and after intervention. RESULTS: The intervention compared with the control condition had no effect on sensory OIPN (mean difference [] = -0.01; P > .99), motor OIPN (=2.39; P = .17), and QOL (= -1.43; P > .99). Eight-week sensory (=11.48 ± 0.38) and motor OIPN severities ( = 7.48 ± 0.36) were mild but higher than baseline (P ≤ .01). Self-reported PA level increased over time in both groups (=44.85; P = .01). Averaging ≥225 moderate to vigorous PA minutes per week led to less sensory OIPN, particularly finger/hand tingling (= -26.35; P = .01). CONCLUSIONS: This study failed to detect beneficial effects of the MI-Walk intervention; however, the findings suggest that aerobic walking may blunt but not completely prevent OIPN. Further research is necessary. IMPLICATIONS FOR PRACTICE: Although the effectiveness of brisk walking in reducing OIPN is unclear, this study supports prior evidence that moderate to vigorous PA is beneficial and safe during chemotherapy treatment.

RESUMO

Objective.The ActiGraph is commonly used for measuring sedentary behavior (SB), but the best data processing technique is not established for sedentary adults with chronic illness. The purpose of this study was to process ActiGraph vertical axis and vector magnitude data with multiple combinations of filters, non-wear algorithm lengths, and cut-points and to compare ActiGraph estimates to activPAL-measured sedentary time in sedentary adults with chronic obstructive pulmonary disease (COPD).Approach.This study was a secondary analysis of adults ≥50 years (N = 59; mean age: 69.4 years;N = 31 males) with COPD. Participants woreActiGraph GT9XandactivPAL3for 7 d. ActiGraph vertical axis and vector magnitude data were processed using combinations of filters (normal, low frequency extension (LFE)), non-wear algorithm lengths (60, 90, 120 min), and cut-points for SB previously validated in older adults (two for vertical axis and three for vector magnitude data). The Bland-Altman method was used to assess concordance between sedentary time measured with 30 ActiGraph techniques and activPAL-measured sedentary time.Main results. Agreement between the two devices was moderate to strong for all techniques; concordance correlations ranged from 0.614 to 0.838. Limits of agreement were wide. The best overall technique was vector magnitude data with LFE filter, 120 min non-wear algorithm, and <40 counts/15 s SB cut-point (concordance correlation 0.838; mean difference -11.7 min d-1).Significance. This analysis supports the use of ActiGraph vector magnitude data and LFE filter in adults with COPD, but also demonstrates that other techniques may be acceptable with appropriate cut-points. These results can guide ActiGraph data processing decisions.

RESUMO

Sedentary behavior contributes to health decline and frailty in older adults, especially the oldest old. The purpose of this systematic review was to synthesize evidence describing the volume of device-measured sedentary behavior and factors that influence sedentary behavior in community-dwelling adults aged 80 and older. Four electronic databases were searched in August 2018; the search was updated in September 2019 and December 2020. Twenty-one articles representing 16 unique datasets from six countries met inclusion criteria. Various devices and data processing methods were used to measure sedentary behavior; the most common device was the ActiGraph accelerometer. Sedentary time during the waking day ranged from 7.6 to 13.4 h/day. Studies using similar measurement methods (hip-worn ActiGraph with uniaxial cut-point <100 counts per minute) had a weighted mean of 10.6 h/day. Subgroup analyses revealed that male gender and age ≥85 may contribute to increased sedentary behavior. Only seven individual articles examined factors that influence sedentary behavior in the 80 and older age group; older age, male gender, non-Hispanic white race/ethnicity, social disadvantage, and declining cognitive function (in men) were associated with increased sedentary behavior. In conclusion, the oldest old are highly sedentary and little is known about factors that influence their sedentary behavior.

RESUMO

Background: People with chronic obstructive pulmonary disease (COPD) are stigmatized by smoking history. Although little is known about COPD-related stigma, it can adversely affect self-management and quality of life. Objective: To synthesize relevant scientific literature exploring stigma experiences and their impacts on people with COPD. Methods: CINAHL/PsycINFO/PubMed/Scopus were searched for relevant studies. Findings were organized using Major et al's conceptual model. Results: Fifteen studies documented COPD-related stigma processes: enacted, felt, internalized, and anticipated. Moderating factors included visibility, origin, and illness perception. Individual-level stigma responses included emotional distress, limited social interactions, and negative effects on medication adherence and help-seeking. Social/community-level stigma experiences included healthcare provider and employer behaviors. Smoking is interwoven throughout all domains of stigma processes and responses to stigma. Conclusion: Substantial evidence documents processes, moderating factors, and individual and social/community responses to the complex phenomenon of COPD-related stigma; however, prevalence of COPD-related stigma and its health effects are unclear.

RESUMO

AIMS AND OBJECTIVES: To identify, appraise and summarise systematic reviews of exercise interventions for surgical lung cancer patients. BACKGROUND: Low exercise capacity, reduced pulmonary function, impaired health-related quality of life and postoperative pulmonary complications are common in surgical lung cancer patients. Numerous systematic reviews address these health problems and examine the effects of exercise intervention. However, differences in the quality and scope of the systematic reviews and discordant findings from the reviews make it difficult for decisions-makers to interpret the evidence and establish best practices in the clinical settings. DESIGN: Overview of systematic reviews. METHODS: This overview was conducted following the PRISMA guideline. A literature search of PubMed, CINAHL, EMBASE, Cochrane Library, SPORTDiscus and PEDro was conducted (October 2019). Peer-reviewed systematic reviews of randomised controlled trials focusing on the effects of exercise interventions for lung cancer patients who underwent surgery were included. The methodological quality of included reviews was assessed using AMSTAR 2. The results of reviews with meta-analysis were synthesised and presented by each health outcome. RESULTS: Seven systematic reviews published between 2013 and 2019 were included. High/moderate-quality evidence showed that postoperative exercise interventions could increase the exercise capacity and muscle strength, and low/very-low-quality evidence showed that postoperative exercise interventions may increase the physical component of health-related quality of life and decease dyspnoea. Low-quality evidence showed that preoperative exercise interventions may increase exercise capacity and pulmonary function, decrease the risk of postoperative pulmonary complications and reduce the length of hospital stay. CONCLUSIONS: Postoperative and preoperative exercises have the potential to improve health outcomes in surgical lung cancer patients. Further research is needed to evaluate the effects of different types of exercise and varying amounts of exercise. RELEVANCE TO CLINICAL PRACTICE: This study provides evidence to support the implementation of exercise interventions for surgical lung cancer patients.
