The Feasibility of a Lifestyle Physical Activity Intervention for Black Women with Asthma

Asthma morbidity measures across Black ethnic subgroups

BACKGROUND

Black adults are disproportionately affected by asthma and are often considered a homogeneous group in research studies despite cultural and ancestral differences.

OBJECTIVE

We sought to determine if asthma morbidity differs across adults in Black ethnic subgroups.

METHODS

Adults with moderate-severe asthma were recruited across the continental United States and Puerto Rico for the PREPARE (PeRson EmPowered Asthma RElief) trial. Using self-identifications, we categorized multiethnic Black (ME/B) participants (n = 226) as Black Latinx participants (n = 146) or Caribbean, continental African, or other Black participants (n = 80). African American (AA/B) participants (n = 518) were categorized as Black participants who identified their ethnicity as being American. Baseline characteristics and retrospective asthma morbidity measures (self-reported exacerbations requiring systemic corticosteroids [SCs], emergency department/urgent care [ED/UC] visits, hospitalizations) were compared across subgroups using multivariable regression.

RESULTS

Compared with AA/B participants, ME/B participants were more likely to be younger, residing in the US Northeast, and Spanish speaking and to have lower body mass index, health literacy, and <1 comorbidity, but higher blood eosinophil counts. In a multivariable analysis, ME/B participants were significantly more likely to have ED/UC visits (incidence rate ratio [IRR] = 1.34, 95% CI = 1.04-1.72) and SC use (IRR = 1.27, 95% CI = 1.00-1.62) for asthma than AA/B participants. Of the ME/B subgroups, Puerto Rican Black Latinx participants (n = 120) were significantly more likely to have ED/UC visits (IRR = 1.64, 95% CI = 1.22-2.21) and SC use for asthma (IRR = 1.43, 95% CI = 1.06-1.92) than AA/B participants. There were no significant differences in hospitalizations for asthma among subgroups.

CONCLUSIONS

ME/B adults, specifically Puerto Rican Black Latinx adults, have higher risk of ED/UC visits and SC use for asthma than other Black subgroups.

Exercise and asthma - Trigger or treatment?

Exercise is one of the most commonly reported symptom triggers for people with asthma. However, a growing body of evidence indicates that regular exercise and physical activity are associated with improved clinical and patient reported outcomes. In this article, we summarise and consolidate recent original studies evaluating exercise and physical activity profiles in people with asthma and provide an up-to-date perspective concerning the role of exercise training and physical activity promotion in the context of asthma management. To conclude, we identify key unmet needs and provide directions for future research.

Ensuring equitable access to guideline-based asthma care across the lifespan: Tips and future directions to the successful implementation of the new NAEPP 2020 guidelines, a Work Group Report of the AAAAI Asthma, Cough, Diagnosis, and Treatment Committee

The most recent recommendations from the 2020 National Asthma Education and Prevention Program Update and Global Initiative for Asthma 2021 guide evidence-based clinical decision making. However, given the present state of health disparities by age, income, and race, the equitable implementation and dissemination of these guidelines will be unlikely without further guidance. This work group report reviews the current state of the new asthma guideline implementation; presents updated evidence-based therapeutic options with attention to specific patient populations; and addresses barriers to the implementation of these guidelines in minoritized, historically marginalized, and underresourced communities. Allergists and immunologists can use practical ways to accomplish the goals of improved asthma care access and advanced asthma care across the life span, with specific considerations to historically marginalized populations. Modifiable barriers to guideline implementation include financial barriers, environmental factors, and allergy subspecialty access and care coordination. Various programs to improve access to guideline-based asthma care include community programs, school-based asthma programs, and digital health solutions, with an emphasis on reducing disparities by race.

Physical activity promotion interventions in chronic airways disease: a systematic review and meta-analysis

Physical inactivity is common in people with chronic airways disease (pwCAD) and associated with worse clinical outcomes and impaired quality of life. We conducted a systematic review and meta-analysis to characterise and evaluate the effectiveness of interventions promoting step-based physical activity (PA) in pwCAD. We searched for studies that included a form of PA promotion and step-count outcome measure. A random-effects model was used to determine the overall effect size using post-intervention values. 38 studies (n=32 COPD; n=5 asthma; n=1 bronchiectasis; study population: n=3777) were included. Overall, implementing a form of PA promotion resulted in a significant increase in step-count: median (IQR) 705 (183-1210) when compared with usual standard care: -64 (-597-229), standardised mean difference (SMD) 0.24 (95% CI: 0.12-0.36), p<0.01. To explore the impact of specific interventions, studies were stratified into subgroups: PA promotion+wearable activity monitor-based interventions (n=17) (SMD 0.37, p<0.01); PA promotion+step-count as an outcome measure (n=9) (SMD 0.18, p=0.09); technology-based interventions (n=12) (SMD 0.16, p=0.01). Interventions promoting PA, particularly those that incorporate wearable activity monitors, result in a significant and clinically meaningful improvement in daily step-count in pwCAD.

Results From a National Survey of Asthma Provider Beliefs and Practices Regarding Exercise and Asthma: A Work Group Report of the AAAAI Committee on Sports, Exercise, and Fitness

BACKGROUND

National Heart, Lung, and Blood Institute guidelines recommend regular physical activity (PA) for patients with asthma. Health care provider (HCP) counseling represents an effective approach to optimizing patient PA. However, current exercise rates among asthma patients are suboptimal, which suggests that counseling may be improved.

OBJECTIVE

To understand PA counseling behaviors among HCPs who manage asthma.

METHODS

A voluntary 36-item survey assessing self-reported awareness of PA recommendations and current clinical practices was sent to 979 randomly selected HCP members of the American Academy of Allergy, Asthma & Immunology (AAAAI).

RESULTS

The overall response rate was 9.3% (91 of 979). Respondents were physicians (100%) and allergists/immunologists (96%) who reported an average of 18.1 ± 12.3 years in independent practice. Over half (58%) reported personally engaging in 150 min/wk or more of moderate to strenuous PA. Eighty percent of participants were unaware of specific PA guidelines for patients with asthma, yet 66% acknowledged evidence for improved asthma outcomes with moderate exercise. A large majority of respondents believed that patients with asthma (97%) and severe asthma (84%) should pursue exercise. Whereas 90% of respondents support incorporating exercise counseling into asthma care, only 69% regularly counsel asthma patients about PA. Barriers cited included limited time, lack of knowledge regarding how and where to refer patients for exercise, and other medical priorities. Potential facilitators of PA included increasing practitioner education and patient-directed posters in waiting areas.

CONCLUSIONS

Health care providers recognized PA as an important component of asthma care but were often unaware of specific guidelines. Promoting PA counseling may require using a time-efficient approach to implement counseling at each asthma patient encounter.

Kinesiotherapy and physical activity in COPD and Asthma Patients – A Review

Background: Obstructive chronic diseases are a continuous challenge for healthcare perfusionists all over the world. Asthma and Chronic Obstructive Pulmonary Disease (COPD) are the most frequent of these diseases. Respiratory or pulmonary rehabilitation started to gain momentum and it is more frequently used to improve muscle strength, cardiac and respiratory endurance and joint flexibility. The objective of this paper is to establish the current programs of physical activity or kinesiotherapy used in the past year and to reveal if there are any gaps or mismatches in the development of the program or in the instruments used to quantify the results of the rehabilitation programs. Materials and methods: We reviewed a total number of 12 articles, randomized control trials using the search words kinesiotherapy, physical therapy, COPD and asthma from the last year on PubMed.gov, from 11 different countries in order to establish which have similar types of exercises, parameters used in order to compare results and which were the outcomes. Results: The final results are positive, although it is hard to determine a unity because there were so many different parameters used to monitor the patients. The most frequent parameter was the 6MWT used to compare the effectiveness of the physical program in 6 studies. Discussion and conclusions: This review had its limitation in comparing the 12 articles researched because of the different number of patients, the various physical activity and rehabilitation exercises used, but especially because of the many varieties of scales and scores used to monitor the effectiveness of the treatment. In order to successfully compare such papers, an international guideline is necessary to relay specific rehabilitation programs for every type of respiratory pathology and also which are the most recommended scales or scores or parameters in general to asses such rehabilitation programs.

An Online Weight Loss Intervention for People With Obesity and Poorly Controlled Asthma

BACKGROUND

Weight loss might improve asthma control in people with obesity. However, people with asthma might have particular challenges losing weight and the amount of weight loss needed to improve asthma control is not clear.

OBJECTIVES

To pilot-test an online weight loss intervention and to estimate the impact of weight loss on asthma control.

METHODS

We performed a 6-month, single-arm, futility trial of an online weight loss intervention at 2 centers. To reject the assumption of futility, 9 or more participants had to lose at least 5% of their body weight. We also assessed the association between weight loss (≥5%) and asthma outcomes.

RESULTS

Forty-three participants (85% women) started the weight loss intervention. The median and interquartile range for the body mass index was 40.3 kg/m² (range 34.7-46.8 kg/m²), and 14 (range 12-17 kg/m²) for the Asthma Control Test score. At 6 months, 10 participants (23%; 95% CI 12%-39%) lost at least 5% of their initial weight. Weight loss of at least 5% was associated with a clinically and statistically significant improvements in their Asthma Control Test (median [interquartile range] increase of 3 [1 to 7]; P < .05), Marks Asthma Quality of Life Score (-9.5 [-18 to -3]; P = .008), and their general health-related quality of life score (RAND-36; improved by 9.4 [2.8 to 22.5]; P =.014).

CONCLUSIONS

An online weight loss intervention has the potential to meet U.S. Food and Drug Administration guidance for product evaluation (at least a 5% weight loss in 35% of people) for treating obesity, and is associated with a clinically significant improvement in asthma control, quality of life, and overall health-related quality of life.

Recommendations for Physical Activity in Asthma: A Work Group Report of the AAAAI Sports, Exercise, and Fitness Committee

Regular physical activity not only improves general health but also can positively impact asthma outcomes, such as control and quality of life. Despite this, many asthma patients do not engage in regular physical activity because they mistakenly believe that they should restrict exercise participation. Health care providers have an opportunity to influence the physical activity levels of their patients during regular office visits. Nonetheless, health care providers often overlook physical activity counseling as an adjunct to pharmacological therapy in asthma patients, and in particular, overlook physical activity counseling. Some providers who acknowledge the benefits of physical activity report being unaware how to approach a conversation with patients about this topic. To address these issues, members of the Sports, Exercise, and Fitness Committee of the American Academy of Allergy, Asthma, and Immunology (AAAAI) performed a focused literature search to identify and evaluate the effects of physical activity in patients with asthma. The purpose of this report is to summarize the evidence for physical activity's impact on asthma patients' disease control, pulmonary function, and overall well-being. Several subpopulations of patients with asthma, including children, adolescents, and older adults, are considered individually. In addition, this report offers practical recommendations for clinicians, including how to identify and overcome barriers to counseling, and methods to incorporate physical activity counseling into asthma treatment practice.
