Nowadays, large amounts of data are emerging medical and nonmedical issues such as political, economic, and social issues. In the field of medical research, a large data collection is useful in investigating allergic diseases. Allergic diseases (e.g., asthma, allergic rhinitis, atopic dermatitis, and urticaria) are common chronic diseases in the general population. Their prevalence and economic burden are increasing worldwide. Thus, the management of allergic diseases has become an important issue in the medical field. Many studies have revealed the prevalence and risk factors of allergic diseases. Through these studies, genetic, environmental, and socioeconomic factors of the development and aggregation of allergic diseases have been identified. However, the real risk factors of allergic diseases in the general population remain obscure because of the methodological limitation of previous epidemiological studies. We are currently in the era of large data collection, and new studies that use large data sets from government agencies, massive companies, international organizations, and so on have been introduced. Based on reported research data, the causes, economic burden, and real prevalence of many diseases have been identified. In particular, allergic diseases can be prevented and controlled by identifying their definitive risk factors.

Thus, we invite investigators to publish research and review papers that examine the risk factors of allergic diseases by using large, innovative data sets from government agencies, international medical organizations, and other credible medicine-related institutes.

Potential topics include but are not limited to the following:

• Results of studies based on credible data
• Allergic diseases such as asthma, allergic rhinitis, atopic dermatitis, urticaria, anaphylaxis, food allergy, and drug allergy
• Environmental, ecological, and climate-related factors
• Regional, socioeconomic, and sociodemographic factors
• Genetic, behavioral, dietary, and medical factors
