Pregnancy results in a variable course for asthma control, likely contributed to by physiological changes affecting the respiratory, immune, and hor-monal systems. While asthma during pregnancy has been associated with an increased risk of maternal and fetal complications including malformations, available data also suggest that active asthma management and monitoring can decrease the risk of adverse outcomes. The diagnosis, disease classifcation, and goals for asthma management in the pregnant woman are the same as for nonpregnant patients. However, evidence shows that pregnant asthmatics are more likely to be under-treated, resulting in asthma exacerbations occurring in approximately one third and hospitalization in one tenth of patients. Pharmacotherapeutic management of asthma exacerbations in pregnant patients follows stan-dard treatment guidelines. In contrast, the principles of asthma maintenance therapy are slightly modified in the pregnant patient. Patients and practitioners may avoid use of asthma medications due to concern for a risk of fetal complications and malformations. A variable amount of information is available regarding the risk of a given asthma medication to cause adverse fetal out-comes, and it is preferable to use an inhaled product. Nevertheless, based on available data, the majority of asthma medications are regarded as safe for use during pregnancy. And, any increased risk to either the mother or fetus from medication use appears to be small compared to that associated with poor asthma control.展开更多

In China, while national data of asthma prevalence are still lacking, an epidemiological study in Beijing showed that the prevalence of asthma in occupational populations was 1.25%. Based on epidemiological data reported in different regions, it is estimated that 15-20 million people suffer from asthma in the mainland of China,^4 and its prevalence continues to rise. A national epidemiological study of childhood asthma in the year of 2000 showed that the prevalence of asthma in urban children under the age of 14 years was 0.12%-3.34% in different regions,展开更多
