Path Analysis of Effects of First-Generation Status on Physical Activity and 4-Year College Degree Completion.

PURPOSE: First-generation college students (FGCS) face a myriad of sociocultural, financial, and emotional challenges that impact their educational journey. With less academic capital and lower odds of obtaining a bachelor's degree than their non-FGCS peers, understanding the factors affecting their academic success is pivotal for social work professionals aiming to provide tailored interventions and support systems. This study delved into the potential differences between these groups concerning physical activities, which are linked to learning, cognition, and overall well-being, and evaluated their influence on degree completion. METHOD: A path model was developed to analyze the relationship between degree completion, physical activities, FGCS status, and background variables, using a sample of 1,625 participants. RESULTS: The model showed a strong fit (CFI = 0.979, RMSEA = 0.055, SRMR = 0.010) and accounted for 29.5% of the variance in degree completion. Walking to school was positively associated with degree attainment. FGCS status was associated with decreased walking to school, reduced degree completion, and increased walking for exercise. An indirect effect suggested that FGCS were less likely to achieve their degree, potentially due to a greater reliance on transportation like buses or cars. DISCUSSION: The findings emphasize the critical role of campus resources for FGCS. Enhancing access to fitness centers and offering affordable housing options nearer to campus may aid FGCSs' academic success. These insights can guide social work practices, highlighting the importance of environmental factors in the academic experiences of FGCS.

Accelerometry measures of physical activity and sedentary behavior: Associations with cognitive functioning in MS.

BACKGROUND: Cognitive dysfunction is a pervasive symptom of multiple sclerosis (MS). Correlational evidence on the relationships between physical activity, sedentary behavior, and cognition has been mixed and limited to a few activity measures. The collinearity of accelerometry-based metrics has precluded an assessment of the full activity spectrum. Here, we aimed to examine the rich set of activity measures using analytic approaches suitable for collinear metrics. We investigated the combination of physical activity, sedentary, and clinicodemographic measures that explain the most variance in composite scores of working memory/processing speed, visual memory, and verbal memory. METHODS: We analyzed baseline accelerometry and neuropsychological data (n = 80) from a randomized controlled trial of pedometer tracking. Using partial least squares regression (PLSR), we built three models to predict latent scores on the three domains of cognition using 12 activity metrics, sex, education, and Expanded Disability Status Scale (EDSS) scores. Significance was assessed using linear regression models with model component scores as predictors and cognitive composites as outcomes. RESULTS: The latent component was significant for working memory/processing speed but was not significant for visual memory and verbal memory after Bonferroni correction. Working memory/processing speed was positively associated with average kilocalories, moderate-to-vigorous physical activity (MVPA), steps, and sex (i.e., higher scores in males) and negatively related to duration of long sedentary bouts and EDSS. CONCLUSIONS: These findings suggest that increasing overall energy expenditure through walking and MVPA, while decreasing prolonged sedentary time may positively benefit working memory/processing speed in people with MS. TRIAL REGISTRATION: This RCT #NCT03244696 was registered on Clinicaltrials.gov (https://www. CLINICALTRIALS: gov/ct2/show/NCT03244696).

Feasibility and impact of a remote moderate-intensity yoga intervention on stress and executive functioning in working adults: a randomized controlled trial.

The feasibility of a moderate-intensity yoga intervention, delivered remotely via supervised and unsupervised sessions, and its psychosocial and cognitive effects have not been thoroughly investigated. This randomized controlled trial assessed feasibility and preliminary efficacy of an 8-week moderate-intensity yoga intervention (3×/week, 50 min) delivered remotely (vs. a waitlist control arm), on stress and cognitive functioning. Participants (n = 86) were low active, full-time working adults (81.40% female; Mage = 41 years) with symptoms of stress. Feasibility was assessed via adherence, enjoyment, and safety; stress and anxiety via self-report questionnaires; and executive functioning via neuropsychological tests. Overall attendance was 75.1%, 100% of participants enjoyed the intervention, and only one adverse event was reported. At follow-up, the yoga group had significantly lower stress and anxiety, and higher accuracy on working memory tasks. Remote moderate intensity yoga practice proved safe, enjoyable, and may reduce stress and improve cognitive functioning. This study was pre-registered on ClinicalTrials.gov (NCT04740229).

Subjective Thirst in Relation to Interdialytic Weight Gain: A Systematic Review of Observational Studies.

INTRODUCTION: Hemodialysis (HD) patients are often prescribed salt and fluid-restricted diets to reduce their interdialytic weight gain (IDWG) and prevent chronic volume overload and hypertension. However, adherence to fluid restrictions is poor, which may be due to HD patients' excessive thirst. The purpose of the review is to explore the association between HD patients' subjective thirst and IDWG, which may inform strategies to manage chronic volume overload. METHODS: We conducted the literature search in Web of Science, Cumulative Index to Nursing and Allied Health Literature, PubMed, and the Cochrane Library, until February 25, 2019. Studies performing statistical tests to assess the association between patients' subjective thirst and IDWG were included. RESULTS: A total of eighteen studies were included in the systematic review, which measured the relationship between patients' subjective thirst and IDWG. Among them, 14 studies found that different domains of thirst and different units of IDWG are positively associated. Therefore, there is a positive association between the patients' subjective thirst and IDWG. However, the findings should be interpreted cautiously as there was variability in thirst and IDWG measurement techniques, which might influence the estimated relationship in these studies. DISCUSSION/CONCLUSION: These data suggest that strategies are needed to reduce thirst to control IDWG in HD patients.

Feasibility and Preliminary Efficacy of Two Technology-assisted Vocal Interventions for Older Adults Living in a Residential Facility.

OBJECTIVES/HYPOTHESIS: An increasing number of older adults are seeking behavioral voice therapy to manage their voice problems. Poor adherence to voice therapy is a known problem across all treatment-seeking populations. Given age-related physical and cognitive impairments and multiple chronic conditions, older adults are more susceptible to low adherence to behavioral therapies. The purpose of this study was to test the feasibility of an at-home, vocal training intervention for older adults without a known voice disorder living in a senior living community, as well as compare the effects of two modes of mobile health (mHealth) technology-assisted vocal training targeting vocal function and adherence in older adults. STUDY DESIGN: Cohort Study (Prospective Observational Study). METHODS: Twenty-three individuals were recruited from a single residential retirement community and randomly allocated into two experimental groups. Both groups were asked to practice the Vocal Function Exercises with increasing frequency over an 8-week period. Tablets with instructions for performing the exercises were provided to all participants. The feedback group's tablets also contained an application providing real-time feedback on pitch, loudness, and duration. Acoustic and aerodynamic measures of vocal function and cognitive measures were obtained before and after the intervention. Self-reported measures of practice frequency, perceived vocal progress and changes, and motivation were obtained weekly. RESULTS: The feedback control group adhered to the requested practice sessions more in the latter half of the intervention (weeks 5 and 8). Vocal function measures remained stable. Overall, a pattern reflecting self-reported vocal progress and a general improvement in working memory and global cognitive functioning was observed in the feedback group. CONCLUSIONS: This study demonstrated that an 8-week mHealth intervention is viable to facilitate vocal practice in older adults. Although vocal ability did not improve with training, results indicated that vocal performance remained stable and age-related vocal changes did not progress. Future research on implementation of mHealth applications in conjunction with behavioral voice therapy is warranted to assess adherence and improvements in vocal function in individuals with age-related voice problems.

Protocol for a randomized controlled trial of mindfulness-based stress reduction to improve attentional control in older adults (HealthyAgers trial).

BACKGROUND: Mindfulness meditation is a form of mind-body intervention that has increasing scientific support for its ability to reduce age-related declines in cognitive functioning, improve affective health, and strengthen the neural circuitry supporting improved cognitive and affective health. However, the majority of existent studies have been pilot investigations with small sample sizes, limited follow-up data, and a lack of attention to expectancy effects. Here, we present the study design of a Phase I/II, efficacy trial-HealthyAgers trial-that examines the benefits of a manualized mindfulness-based stress reduction program in improving attentional control and reducing mind-wandering in older adults. METHODS: One hundred fifty older adults (ages 65-85 years) will be randomized into one of two groups: an eight-week mindfulness program or an eight-week, placebo-controlled, lifestyle education program. Behavioral and neuroimaging assessments are conducted before and after the training. Participants are then invited to booster sessions once every three months for a period of 12 months with post-intervention follow-up assessments conducted at 6-months and 12-months. The primary outcomes for the study are behavioral measures of attentional control and mind-wandering. Additional, secondary outcomes include network strength in an a priori defined neuromarker of attentional control, fluid and everyday cognition, emotion regulation strategy use, and markers of inflammation. DISCUSSION: This study will establish the efficacy of a group-based, low-cost mind-body intervention for the inter-related facets of attentional control and mind-wandering in older adults. Strengths of this study include a well-designed, placebo-controlled comparison group, use of web/mobile application to track study adherence, and longitudinal follow-up.

Exploring Active Travel and Leisure-Time Physical Activity Relationships With Cognition Among Older Adults.

Leisure-time physical activity (LTPA) is known to benefit cognition among older adults, but the impact of active travel is unclear. To explore this relationship, data from the 2011-2014 National Health and Nutritional Examination Survey (N = 2,702; mean age = 70) were retrieved on the self-reported frequency and duration of active travel (walking/cycling for transport, >20 min), LTPA engagement (e.g., sport), and three cognitive outcomes. Four groups were created according to physical activity guidelines (600 metabolic equivalent of task/week): inactive (n = 1,790), active travelers (n = 210), engaging in LTPA (n = 579), and engaging in both (n = 123). Analysis of covariance (and follow-up comparisons) revealed a significant main effect for each cognition variable, after adjusting for the covariates, indicating that those engaging in LTPA performed the best. Although correlational, these findings suggest that LTPA engagement may be important for cognition among older adults, but active travel did not provide added benefit.

Active Commute in Relation to Cognition and Academic Achievement in Children and Adolescents: A Systematic Review and Future Recommendations.

Active commuting to school (ACS) is an important source of physical activity among children. Recent research has focused on ACS and its benefits on cognition and academic achievement (AA), factors important for success in school. This review aims to synthesize literature on the relationship between ACS and cognition or AA among children and adolescents. Peer-reviewed articles in PubMed, Web of Science, PsycINFO and Cochrane Library assessing ACS with cognition and/or AA among children, until February 2019, were selected. Twelve studies across nine countries (age range 4-18.5 years) were included. One study used accelerometers, whereas all others used self-report measures of ACS. A wide range of objective assessments of cognitive functioning and AA domains were used. Five among eight studies, and four among six found a positive relationship between ACS and cognitive or AA measure, respectively. Four studies found dose-response relationships, and some studies found sex differences. The quantitative analysis found that ACS was not significantly associated with mathematics score (odds ratio = 1.18; CI = 0.40, 3.48). Findings are discussed in terms of methodological issues, potential confounders, and the strength of the evidence. Future studies should conduct longitudinal studies and use objective measures of ACS to understand this relationship further.
