Core Insights - The article highlights the increasing prevalence of asthma globally, with over 358 million patients and an expected rise to over 400 million this year, particularly affecting children in China, where over 45 million are affected, including 15 million children [1][2] Group 1: Asthma in Children - Asthma is a common chronic disease among children, often triggered by allergens such as dust mites, pet dander, and certain foods, as well as environmental factors like cold air and vigorous exercise [3][4] - The condition is characterized by bronchial spasms leading to breathing difficulties, with a noted increase in cases due to allergies and viral respiratory infections [3][4] - While asthma cannot be cured, various treatment methods, including inhalation therapy and traditional Chinese medicine, can help manage symptoms and improve quality of life [3][4] Group 2: Asthma in Adults - Adult asthma can present atypically, with symptoms such as chronic cough and nighttime chest tightness, which may be mistaken for common colds [5][6] - Many adults may have experienced asthma symptoms in childhood, which can resurface in adulthood if not properly managed, potentially leading to chronic obstructive pulmonary disease (COPD) [6][7] - Older adults face higher asthma prevalence, often complicated by other chronic conditions, making treatment more challenging and increasing the risk of multi-organ damage [6][7]

Core Insights - The theme for World Asthma Day 2023 is "Ensuring Inhalation Therapy Benefits All Asthma Patients" [1] - Asthma is a prevalent chronic disease, with approximately 260 million patients globally and around 436,000 deaths annually [2] - In China, the asthma prevalence rate among individuals aged 20 and above is 4.2%, equating to about 45.7 million patients [2] Group 1: Understanding Inhalation Therapy - Inhalation therapy is central to asthma treatment, allowing medication to directly enter the airways with fewer systemic side effects [4] - The overall control rate of asthma in urban China is 28.58%, significantly lower than the 40%-50% control rates in developed countries [4] - Misunderstandings about inhalation medications, particularly corticosteroids, contribute to poor treatment adherence, with over 80% of patients stopping medication [2][4] Group 2: Pediatric Asthma - Approximately 7 million children in China suffer from asthma, which can lead to severe respiratory issues during acute episodes [7] - Asthma in children is often linked to allergies, with common triggers including mold, dust mites, and pet dander [9] - Children with a family history of asthma are at a higher risk, with a 2 to 5 times increased likelihood if one parent has asthma, and up to 50% if both parents are affected [9] Group 3: Exercise and Asthma Management - Exercise can be beneficial for asthma patients, improving lung function, but must be approached cautiously [12] - Children with asthma should only engage in physical activity if their condition is well-controlled and under medical guidance [12] - Avoiding allergens and extreme environmental conditions is crucial for asthma patients during exercise [12]
