Pilot evaluation of a behavioral weight loss program for adults with physical disabilities: State of Slim Everybody usability and feasibility.

Background: People with physical disabilities (PWD) have a higher prevalence of obesity than populations without disability, but most evidence-based weight loss programs have not included this population. The State of Slim (SOS) program is an evidence-based weight loss program that has demonstrated success in producing weight loss in populations without disability, but it has not been adapted for or evaluated in PWD. Methods: The SOS program was systematically adapted using the evidence-informed Guidelines, Recommendations, and Adaptations Including Disability (GRAIDs) framework. A total of 35 participants enrolled in the State of Slim Everybody program. The program was offered entirely online. Body weight, attendance, and food log completion were also tracked weekly. The program length was 16.5 h and included weekly group instruction, with optional one-on-one sessions provided upon request. Following completion, participants completed post-evaluation surveys on overall satisfaction with the program. The primary outcomes were program effectiveness (i.e., body weight), usability, and feasibility. Results: Thirty-two out of 35 participants completed the program, representing a retention rate of 91.4%. Average weight loss was 10.9% (9.9 ± 0.7 kg (t (31) = -13.3, p =< 0.0001)). On a 1 (dissatisfied/completely useless) to 5 (very satisfied/completely helpful) Likert scale, the average score for overall program satisfaction was 4.8 ± 0.1 and program helpfulness 4.6 ± 0.1. Conclusion: The State of Slim Everybody program demonstrated significant weight loss and good usability and feasibility in PWD. Existing adaptation frameworks can be used to create inclusive health promotion programs for adults with physical disabilities.

Improvements in nutrition knowledge among adults with physical disabilities: A program evaluation of the mindfulness, exercise, and nutrition to optimize resilience (MENTOR) program 2020-2021.

BACKGROUND: The Centers for Disease Control and Prevention (CDC) funds a quality improvement (QI) health promotion telewellness program for adults with physical disabilities. OBJECTIVE: The nutrition component of the parent program, Mindfulness, Exercise, and Nutrition to Optimize Resilience (MENTOR) program, from 2020 to 2021, was evaluated to assess changes in nutrition knowledge of people with physical disabilities. METHODS: This was a quasi-experimental program evaluation by pre-post survey of participating adults with physical disabilities. Participants attended weekly nutrition classes for eight weeks with optional one-on-one counseling with a Registered Dietitian. Participants completed pre-post General Nutrition Knowledge Questionnaire Revised (GNKQ-R) that were analyzed using paired t-tests. Participants were grouped into quartiles by pre-program GNKQ-R scores for additional comparisons. Program attendance and post-program feedback were also evaluated. RESULTS: A total of 286 participants completed the MENTOR program, and 31% (n = 89) completed pre-post questionnaires for data analysis. Mean pre-program GNKQ-R scores were 58.4 ± 15.1 and post scores were 64.4 ± 11.3, which demonstrated a statistically significant improvement in nutrition knowledge (p < .001). Ancillary analysis revealed that participants with the lowest quartile of pre-program nutrition knowledge had the greatest improvements in their post-GNKQ-R scores (Mean change 16.4 ± 13.9). Questionnaire data revealed participants' subjective knowledge changes and their feedback on the nutrition component of the program. CONCLUSIONS: The eight-week MENTOR program effectively improved nutrition knowledge among people with physical disabilities. This demonstrates the impact the program can have on individual knowledge levels. Additionally, these results support the implementation of the program to the broader population of people with disabilities.

Associations between self-reported symptoms of SARS-CoV-2 and dietary supplement use over the previous year during the first pandemic wave.

During the initial wave of the COVID-19 pandemic, symptoms of infection varied widely among adults younger than 60 years. This cross-sectional investigation of adults ages 18-59 years explored associations between SARS-CoV-2 symptomatology and supplementation of micronutrients involved in immune function, such as multivitamins, vitamin D, vitamin C, vitamin E and zinc. Between August and December 2020, an online survey was completed by 287 respondents, averaging 33⋅3 ± 10⋅5 years, who recovered from SARS-CoV-2 infection within the previous 4 months. In regression models, intake of supplements over the previous year was not protective against number of symptoms or symptom severity. Despite higher rates of supplementation over the previous year, smokers experienced more symptoms and greater symptom severity than non-smokers. Micronutrient supplementation did not protect young adults from experiencing symptoms of SARS-CoV-2, but our results suggest that smoking cessation may be a more effective modifiable lifestyle factor.

Adapting an evidence-based physical activity questionnaire for people with physical disabilities: A methodological process.

BACKGROUND: Practitioners and researchers often adapt tools, practices, and programs to meet the needs of culturally diverse population groups, but do not consider populations with disability. While there is some research on guidelines for adapting evidence-based programs, there is no systematic process for adapting survey instruments. Rather than creating separate instruments for people with physical disabilities (PWD), it is critical that instruments are designed to capture data on people with and without disabilities for comparison purposes. Given the disproportionately high rates of physical inactivity and obesity in PWD, we developed a methodology to adapt an evidence-based physical activity instrument. OBJECTIVE: To create a methodology to adapt surveys to be inclusive of PWD and use the methodology to adapt an evidence-based physical activity survey. METHODS: A framework was developed to adapt a physical activity survey instrument (International Physical Activity Questionnaire, IPAQ) to be inclusive of PWD. The framework, referred to as SAVe-IT, includes five steps: Step 1) Select survey instrument to adapt; Step 2) Adapt the survey instrument; Step 3) Verify adaptations with experts; Step 4) Implement pilot test; Step 5) Test the tool to confirm reliability. RESULTS: The adapted IPAQ passed review by the expert panels and the pilot test (n = 20). Assessment of test-retest reliability (n = 30) yielded strong intraclass correlation coefficients of 0.950 for the total score for the whole sample, 0.950 for PWD (n = 15) and 0.952 for people without disability (n = 15). CONCLUSIONS: The SAVe-IT framework resulted in the successful adaptation of the IPAQ and can be used in populations with and without physical disabilities.

The feasibility and acceptability of a dementia care training program for registered dietitian nutritionists.

There is a need for more Registered Dietitian Nutritionists (RDNs) trained to provide nutritional care to older adults with dementia who experience mealtime difficulties. The purpose of this single-arm, pre/post pilot study was to adapt a generalized dementia care curriculum to the learning needs of RDNs who work with individuals with dementia and to determine the feasibility and acceptability of the adapted program. Using an existing evidence-based dementia care curriculum, the research team identified learning objectives and content pertinent to the scope of RDNs. The adapted program was piloted with RDNs who work with older adults with dementia. Twenty-five RDNs registered for the training while 80% (20) attended the training and completed the post-training survey. All participants agreed that the module met the learning needs of RDNs who work with older adults with dementia, the two-hour workshop was a good use of their time, and the experience and skills gained would be useful in their work as an RDN. Implementation costs totaled $1,310. Based on the post-training feedback, the adapted program was deemed feasible and acceptable by RDN participants, who also expressed interest in using the module to train other caregivers on providing mealtime assistance to older adults with dementia.

A Qualitative Analysis of Experiences With Food-Related Activities Among People Living With Parkinson Disease and Their Care-Partners.

Objectives: The purpose of this qualitative study was to explore factors associated with the ability of people with PD to perform food-related activities (FRAs). Methods: Eleven dyads, older adults with Parkinson disease (PD) and their care-partners (n = 22), completed virtual semi-structured interviews guided by the Social Cognitive Theory (SCT) that were independently analyzed by two coders via directed content analysis. Results: The following themes were identified-(1) Personal: perception of a healthy diet, perception of how nutrition influences PD, confidence in following a healthy diet, and barriers to performing FRA; (2) Environmental: previous sources of nutrition information and willingness to changing their diet with a registered dietitian; and (3) Behavioral: modifications to FRA due to food-medication interactions, and skills necessary to maintain a healthy diet. Discussion: Findings from this study highlight the need for nutrition intervention research to inform evidence-based guidelines in order to provide tailored education for people with PD and care-partners.

A Mixed Methods Exploration of the Impact of the COVID-19 Pandemic on Food-Related Activities and Diet Quality in People with Parkinson Disease.

OBJECTIVE: The purpose of this mixed methods study was to explore the impact of COVID-19 on the ability of people with Parkinson disease (PwPs) and their care-partners to perform food-related activities (FRA) and PwPs' overall diet quality. METHODS: Using a convergent parallel mixed methods design, PwPs and their care-partners completed virtual dyadic semi-structured interviews about their FRA during the COVID-19 pandemic. PwPs completed Food Frequency Questionnaires (FFQ) to quantify their dietary intake in the previous 12 months. Qualitative data were analyzed by two coders using thematic analysis, and quantitative data from FFQs were descriptively analyzed to calculate diet quality scores. RESULTS: Eleven dyadic interviews revealed the following key themes: cooking more at home; changes with grocery shopping; less meals with non-household members. These changes were described to increase the care-partners' responsibilities and overall burden. Diet scores among PwPs were 73.0 ± 6.3 for the Healthy Eating Index 2015 (scale of 0-100), 29.2 ± 6.6 for the Mediterranean diet (scale of 0-55), and 10.4 ± 1.8 for the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet (scale 0-15). CONCLUSIONS: Diet scores revealed that PwPs consumed a high-quality diet during the pandemic. Findings from this study highlight the need for tailored nutrition education to support PwPs' care-partners.

Implementation, spread and impact of the Patient Oriented Discharge Summary (PODS) across Ontario hospitals: a mixed methods evaluation.

BACKGROUND: Traditional discharge processes lack a patient-centred focus. This project studied the implementation and effectiveness of an individualized discharge tool across Ontario hospitals. The Patient Oriented Discharge Summary (PODS) is an individualized discharge tool with guidelines that was co-designed with patients and families to enable a patient-centred process. METHODS: Twenty one acute-care and rehabilitation hospitals in Ontario, Canada engaged in a community of practice and worked over a period of 18 months to implement PODS. An effectiveness-implementation hybrid design using a triangulation approach was used with hospital-collected data, patient and provider surveys, and interviews of project teams. Key outcomes included: penetration and fidelity of the intervention, change in patient-centred processes, patient and provider satisfaction and experience, and healthcare utilization. Statistical methods included linear mixed effects models and generalized estimating equations. RESULTS: Of 65,221 discharges across hospitals, 41,884 patients (64%) received a PODS. There was variation in reach and implementation pattern between sites, though none of the between site covariates was significantly associated with implementation success. Both high participation in the community of practice and high fidelity were associated with higher penetration. PODS improved family involvement during discharge teaching (7% increase, p = 0.026), use of teach-back (11% increase, p < 0.001) and discussion of help needed (6% increase, p = 0.041). Although unscheduled healthcare utilization decreased with PODS implementation, it was not statistically significant. CONCLUSIONS: This project highlighted the system-wide adaptability and ease of implementing PODS across multiple patient groups and hospital settings. PODS demonstrated an improvement in patient-centred discharge processes linked to quality standards and health outcomes. A community of practice and high quality content may be needed for successful implementation.

Visceral adiposity index and its association with Dietary Approaches to Stop Hypertension (DASH) diet scores among older adults: National Health and Nutrition Examination Surveys 2011-2014.

BACKGROUND & AIMS: The visceral adiposity index (VAI) has been shown to be a reliable estimate of visceral adiposity, but little is known about its association with specific dietary patterns such as the Dietary Approaches to Stop Hypertension (DASH) diet, particularly in older adults. Many studies have shown the DASH diet to be beneficial for cardiometabolic health. The purpose of this study was to investigate the relationship between DASH diet scores and the VAI in older adults using a nationally representative dataset. METHODS: Using the National Health and Nutrition Examination Surveys (NHANES) from 2011 to 2014, data from 508 community-dwelling older adults were examined, and dietary intake was evaluated using the Dixon's DASH diet index. Using multiple linear regression analysis, the relationship between VAI and DASH diet score was assessed while controlling for demographic variables. RESULTS: Participants' average DASH diet score was 2.41 (SE = 0.07), and the average VAI was 1.55 (SE = 0.08). The results suggest a significant inverse relationship between the DASH diet and VAI (ß = -0.19, t = -2.73, p = 0.009). CONCLUSIONS: Results of this study suggest that protective properties of the DASH diet pattern may be due in part to its inverse relationship with visceral adiposity. This information supports practitioners' use of the VAI with older adults in addition to providing nutrition counseling with the DASH diet to reduce patients' cardiometabolic risk.

Connected Research: The Potential of the PID Graph.

Persistent identifiers (PIDs) provide unique and long-lasting references to entities. They enable unique identification persistently over time and hence play a crucial role in supporting the FAIR (Findable, Accessible, Interoperable, Reusable) principles. In this paper, we describe how the benefits of PIDs can be amplified by connecting them via their metadata. We are introducing the next step in PID infrastructure: the PID Graph. The PID Graph establishes connections between different entities within the research landscape, thereby enabling both researchers and institutions to access new information. The paper closes with three recommendations, which will help to optimize the use and value of PIDs within the research ecosystem.

"If They Don't Like You, They Are Not Going to Eat for You": Individual and Interpersonal Factors Affecting Certified Nursing Assistants' Ability to Provide Mealtime Assistance to Residents With Dementia.

BACKGROUND AND OBJECTIVES: In long-term care facilities in the United States, certified nursing assistants (CNAs) provide mealtime assistance to residents with dementia, a task that substantially increases caregiver burden due to the time and attention required. The aim of this qualitative study was to explore the individual and interpersonal barriers and facilitators CNAs experience when providing mealtime assistance to residents with dementia. RESEARCH DESIGN AND METHODS: Focus group questions were developed based on the corresponding levels of the Social Ecological Model. Using purposive sampling, 9 focus groups were conducted with 53 CNAs who had at least 1 year of experience as a CNA working with older adults. Focus groups were audio-recorded and transcribed verbatim. Data were analyzed using the directed content analysis approach. RESULTS: CNAs reported individual skills, training, and personal characteristics that affected their ability to provide mealtime assistance. At the interpersonal level, CNAs identified their relationships with residents, residents' family members, and other health care professionals as factors that affect their ability to provide mealtime assistance. DISCUSSION AND IMPLICATIONS: These findings provide evidence for strategies that administrators can utilize to reduce caregiver burden by improving the mealtime experience. First, CNAs need adequate training, particularly to develop communication skills. Developing verbal communication skills may improve interpersonal relationships between CNAs and residents' family members and other coworkers. Developing nonverbal communication skills may foster an improved relationship between CNAs and their residents with dementia. Future research should evaluate interventions that seek to improve these skills to determine their impact on the mealtime experience.

Dietary Supplement Use is High among Individuals with Parkinson Disease.

OBJECTIVES: To assess the present use of dietary supplements among the Parkinson disease (PD) population and to determine which dietary supplements are most commonly taken. METHODS: This cross-sectional study used an online questionnaire that was administered to individuals with PD via support group Web sites. Dietary supplement users also were asked whether they spoke with a healthcare professional about their supplement use. RESULTS: Of the 205 respondents, 83.4% reported taking at least 1 dietary supplement. Although 94 different types of dietary supplements were identified, >50% of participants taking dietary supplements took multivitamins, vitamin D, and vitamin B12 (52.6%, 74.3%, and 56.1%, respectively). Respondents reported taking coenzyme Q10, Mucuna pruriens, folate, vitamin B12, vitamin B6, melatonin, and N-acetylcysteine most commonly for PD. Among supplement users, 29.2% did not discuss their supplement use with a healthcare practitioner. CONCLUSIONS: The results of this study demonstrate a high prevalence of dietary supplement use among individuals with PD, in addition to a wide variety of supplements being taken. This study's findings also indicate the need for better dialog between patients and healthcare practitioners regarding the use of dietary supplements.

The effect of exercise training with an additional inspiratory load on inspiratory muscle fatigue and time-trial performance.

The purpose was to determine the effect of moderate-intensity exercise training (ET) on inspiratory muscle fatigue (IMF) and if an additional inspiratory load during ET (ET+IL) would further improve inspiratory muscle strength, IMF, and time-trial performance. 15 subjects were randomly divided to ET (n=8) and ET+IL groups (n=7). All subjects completed six weeks of exercise training three days/week at ∼70%V̇O2peak for 30min. The ET+IL group breathed through an inspiratory muscle trainer (15% PImax) during exercise. 5-mile, and 30-min time-trials were performed pre-training, weeks three and six. Inspiratory muscle strength increased (p<0.05) for both groups to a similar (p>0.05) extent. ET and ET+IL groups improved (p<0.05) 5-mile time-trial performance (∼10% and ∼18%) and the ET+IL group was significantly faster than ET at week 6. ET and ET+IL groups experienced less (p<0.05) IMF compared to pre-training following the 5-mile time-trial. In conclusion, these data suggest ET leads to less IMF, ET+IL improves inspiratory muscle strength and IMF, but not different than ET alone.

Improved lung function following dietary antioxidant supplementation in exercise-induced asthmatics.

INTRODUCTION: Oxidative stress is a characteristic of exercise-induced asthma (EIA), however antioxidant supplementation may attenuate EIA. The purpose of this study was to determine if ascorbic (AsA) and α-tocopherol supplementation would improve airway function in subjects with EIA. METHODS: A single-blind randomized crossover design with eight clinically diagnosed EIA subjects (22.0 ± 0.7 year) and five healthy control subjects (28.2 ± 1.4 year) was used. Subjects consumed vitamins (V) (AsA 500 mg; α-tocopherol 300 IU) or placebo (PLA) daily for three weeks, followed by a three week washout period and then three weeks of the alternative treatment. Ten-minute treadmill tests (90% VO2peak) were performed with pulmonary function testing (forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and between 25 and 75% (FEF25-75%), and peak expiratory flow rates (PEFR)) measured pre-exercise and 1, 5, 15, and 30 min post-exercise. RESULTS: Supplementation led to significant improvements at minute 5 and minute 15 in FVC; FEV1; PERF; FEF25-75% and minute 30 in FEV1 and FEF25-75% post-exercise. CONCLUSION: AsA and α-tocopherol may aid the recovery of pulmonary function in subjects with EIA.

The effects of antioxidant vitamin supplementation on expiratory flow rates at rest and during exercise.

PURPOSE: Previous studies suggest that pulmonary function is associated with fruit and vegetable consumption and plasma concentrations of antioxidant vitamins. Also, expiratory flow limitation (EFL) has been reported to limit ventilation during exercise in healthy individuals. We hypothesized antioxidant vitamin supplementation (AVS) would increase resting expiratory flow rates in healthy subjects and reduce EFL during exercise. METHODS: Ten healthy, nonsmoking subjects (5 M/5 W), consuming <5 servings of fruit and vegetables per day, participated in a randomized, single-blinded crossover design study with subjects receiving a placebo (PLA) or AVS [vitamins C (500 mg), E (400 IU), beta-carotene (15,000 IU), zinc (7.5 mg), selenium (50 mg), copper (1 mg), and manganese (2.5 mg)] for 4 weeks. After a minimum 4-week washout period, subjects received the alternate supplementation. Pulmonary function tests and total antioxidant status (TAS) from plasma were measured pre- and post-supplement period. Subjects completed a pre- and post-supplement treadmill test for 20 min at 70% [Formula: see text] followed by increasing workload until exhaustion. RESULTS: AVS increased (p < 0.05) TAS by ~21% and resting expiratory flow rates (FEF25-75, FEF50) by ~9%. Following AVS, %EFL was significantly reduced by ~15% at minute 15, 20, and end-exercise with no change (p > 0.05) in end-expiratory lung volumes. Breathing frequency and ratings of perceived exertion and dyspnea were also lower (p < 0.05) at min 20 of exercise. No changes (p > 0.05) were evident at rest or during exercise with PLA. CONCLUSIONS: These results suggest that AVS can increase TAS, improve resting expiratory flow rates and reduce EFL during exercise in healthy subjects who are not meeting fruit and vegetable recommendations.

Disparities in physician-patient communication by obesity status.

This study aimed to examine variations in patient-physician communication by obesity status. We pooled data from the 2005-2007 Medical Expenditure Panel Survey (MEPS),_included only individuals who completed the self-administered questionnaire themselves, and restricted the sample to patients who received care from primary care physicians. We included a total of 6,628 unique individuals between the ages of 18 and 65 who had at least one office or hospital outpatient visit during the past 12 months. There are six outcomes of interest in this study. The patient-physician communication composite score is based on five questions that the MEPS adapted from the Consumer Assessment of Healthcare Providers and Systems Survey. The other five variables were: respect from providers, providers' listening skills, explanations from providers, time spent with patients, and patient involvement in treatment decisions. The key independent variable was obesity. Bivariate and multivariate models such as ordinary least squares (OLS) and logistic regression were used to examine the relationship between patient-physician communication and obesity status. Multivariate models showed that obese patients had a reduced physician-patient communication composite score of 0.19 (95% CI 0.03-0.34, p=0.02), physicians' show of respect OR 0.77 (95% CI 0.61-0.98, p=0.04), listening ability OR 0.82 (95% CI 0.65-1.02, p=0.07), and spending enough time OR 0.80 (95% CI 0.62-0.99, p=0.04) compared to non-obese patients. We found a negative association between physician-patient communication and patients' obesity status. These findings may inform public health practitioners in the design of effective initiatives that account for the needs and circumstances of obese individuals.
