ABSTRACT
<p><b>OBJECTIVE</b>To compare the clinical features in children with different control levels of asthma and to explore the factors influencing asthma control.</p><p><b>METHODS</b>A cross-sectional study was performed on 115 children diagnosed with asthma between October 2013 and February 2014. All the patients were classified into two groups: fully controlled group (n=65) and non-fully controlled group (n=55), according to the Children Bronchial Asthma Prevention and Treatment Guideline (2008 version) and the asthma control test results. The differences of clinical features between the two groups were compared. The quality of life was evaluated by an asthma-related quality of life questionnaire. The main factors influencing asthma control were analyzed by the logistic regression method.</p><p><b>RESULTS</b>There were significant differences in the frequencies of respiratory tract infection and acute asthma attacks within the 3 months, and unplanned hospital visits due to acute asthma attacks between the fully controlled and non-fully controlled groups (P<0.05). The scores of asthma-related quality of life in the fully controlled group were significantly lower than in the non-fully controlled group in children under 7 years old. In contrast, the scores of asthma-related quality of life in the fully controlled group were significantly higher than in the non-fully controlled group in children at the age of 7-16 years (P<0.05). The logistic regression analysis showed that the patients without experiencing regular hospital visits (OR=7.715) and with allergic rhinitis (OR=5.531) had increased risks for poor asthma control and that the patients with other allergic diseases (eg. eczema, food allergy) had decreased risks for poor asthma control (OR=0.299).</p><p><b>CONCLUSIONS</b>The appearance of some clinical features suggests that the asthmatic children may be in the status of poor asthma control and need an active intervention. A poor asthma control status can result in a decreased quality of life. To improve the asthma control level, the incidence of allergic rhinitis should be reduced and a regular hospital visit should be performed in the children.</p>

<p><b>OBJECTIVES</b>To study the knowledge, attitude and practice (KAP) concerning asthma in parents of children with asthma and the related factors.</p><p><b>METHOD</b>Questionnaire survey was conducted by using the multi-center research methods in twenty hospitals with asthmatic clinic or pediatric clinic in Beijing from August to October in 2008. The investigation focused on Beijing permanent residents with children who have been diagnosed as asthma for more than 6 months.</p><p><b>RESULT</b>Totally 390 parents of asthmatic children were investigated among whom 351 provided valid questionnaires, the response rate reached 90.0%; 75.2% of the parents knew that the nature of asthma is a chronic allergic airway inflammatory disease; 54.4% of parents think that even if the child is in a state of asthma control he/she can participate in only mild exercise; 88.4% of parents consider that the long-term use of inhaled corticosteroid would have a mild effect on growth and development of children. Of the asthmatic children, 32.5% adhered to use inhaled corticosteroid prescription; 47.2% adhered to use leukotriene receptor modulator; 45.3% of parents of children with acute asthma attack will add antibiotics; 18.1% of parents would choose short-acting beta2-agonist. The multi-factors Logistic regression suggested that the parents' educational background and the frequency of referral in children with asthma under control may have an influences on the parents' KAP (P < 0.05, OR > 1).</p><p><b>CONCLUSION</b>The general understanding of asthma in asthmatic children's parents in Beijing area is good, the higher the parents' educational background and revisit frequency of asthmatic children whose disease is under control, the better the Parents' KAP.</p>
