Climate change and its impact on asthma.

ABSTRACT: Earth's climate is changing at an unprecedented pace, primarily due to anthropogenic causes including greenhouse gas emissions. Evidence shows a strong link between climate change and its effects on asthma. Healthcare professionals must be educated to advocate for and lead effective strategies to reduce the health risks of climate change.

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.

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.

Work Group Report: Perspectives in Diagnosis and Management of Exercise-Induced Bronchoconstriction in Athletes.

Exercise-induced bronchoconstriction, otherwise known as exercise-induced bronchoconstriction with asthma or without asthma, is an acute airway narrowing that occurs as a result of exercise and can occur in patients with asthma. A panel of members from the American Academy of Allergy, Asthma & Immunology Sports, Exercise, & Fitness Committee reviewed the diagnosis and management of exercise-induced bronchoconstriction in athletes of all skill levels including recreational athletes, high school and college athletes, and professional athletes. A special emphasis was placed on the recommendations and regulations set forth by professional athletic organizations after a detailed review of their collective bargaining agreements, substance abuse policies, antidoping program manuals, and the World Anti-Doping Agency antidoping code. The recommendations in this review are based on currently available evidence in addition to providing guidance for athletes of all skill levels as well as their treating physicians to better understand which pharmaceutical and nonpharmaceutical management options are appropriate as well as which medications are permitted or prohibited, and the proper documentation required to remain compliant.
