“… 32 In Japan, the number of children hospitalized because of asthma exacerbation decreased from 1996 to 2014. 33 It is possible that asthma control has been improving over time. However, about 1/100 young children in our study suffered from sleep disturbances because of wheeze 1 or more nights per week until the age of 3 years.…”

Background: Capturing epidemiological signatures is essential to document burdens of disease and to design health care services, including prevention measures, clinical interventions, and policies. There are large geographical and ethnic variations in the epidemiology of allergic and immunological diseases. Various data are available from North America and Europe, but the epidemiology of allergic and immunological diseases in Asia is not well documented. Objective: To characterize epidemiological signatures of allergic and immunological disease in young children in Japan. Methods: This was a national, multicenter, prospective birth cohort study: Japan Environment and Children's Study (JECS). A general population of 103,060 women was enrolled during pregnancy. Allergic and immunological outcomes were assessed among young children using questionnaire data. Results: The prevalence of caregiver-reported immediate food allergy was 7.6%, 6.7%, and 4.9% at age 1, 2, and 3 years, respectively. Hen egg allergy was most common (5.4% prevalence at age 1 year) followed by allergies to cow milk and wheat. Several patterns of allergic symptom clusters were identified. Physician diagnosed, as reported by the caregiver, non-IgE mediated gastrointestinal food allergy affected 0.5% of infants. By contrast, caregiver-reported gastrointestinal food allergies affected 1.4% of children. Kawasaki disease affected 0.3% and 0.4% children, respectively, at age 1 and 3 years. Primary immunodeficiency disorders affected 0.005% children at age 3 years. Conclusion: These data provide important epidemiological signatures of allergy and immunology in young Japanese children including the age-specific prevalence of allergic disease, Kawasaki disease, and primary immune deficiency.

Background: Asthma diagnosis in children is occasionally challenging, and the issue of undiagnosed asthma before adolescence has been poorly studied in Japan. The present study was conducted to investigate the possible presence of undiagnosed asthma in the general population of children living in a rural area of Japan.Methods: The participants comprised 120 fourth graders aged 9–10 years (boys/girls: 63/57) attending five elementary schools in Yawatahama, Ehime, Japan. All the children underwent respiratory function tests and fraction of exhaled nitric oxide (FeNO) measurements. Based on the results of a questionnaire, the children were also categorized into groups depending on their allergic diseases.The authors assessed the results of both the respiratory function tests and the FeNO measurements for children who were classified into the nonallergic group.Results: A total of 76 (63%) children, who completed the tests appropriately, were included in the analysis. According to the report, among the 24 children in the nonallergic group, six (25%) showed abnormalities in respiratory tests. One had an abnormal % forced vital capacity (%FVC; <80%), three had abnormalities in both forced expiratory volume in 1 sec (FEV1)/FVC (<80%) and % maximal mid-expiratory flow (<65%), three had concave flow–volume curves, and one had a high FeNO measurement (41 ppb).Conclusion: A certain proportion of Japanese elementary school children, categorized as having no allergy, showed respiratory function test abnormalities. A follow-up study is needed to determine the prognosis and outcomes of the children with these abnormalities.

Studies conducted on allergies in childhood by the American Thoracic Society‐Division of Lung Diseases (ATS‐DLD) and the International Study of Asthma have surveyed the prevalence of childhood asthma in Japan and reported rates of 3.2–6.5% (Arakawa et al, ).

“…Studies conducted on allergies in childhood by the American Thoracic Society‐Division of Lung Diseases (ATS‐DLD) and the International Study of Asthma have surveyed the prevalence of childhood asthma in Japan and reported rates of 3.2–6.5% (Arakawa et al, ). A recent study further indicated that the prevalence of asthma has started to decline (Arakawa et al, ). However, a survey by the Japanese Pediatric Asthma Control program (JPAC) found that the rates of poor asthma control ranged from 32.1% to 47.0%, indicating that many patients are unable to manage their symptoms effectively.…”

“…Challenges regarding the continuous management of asthma patients persist (Hashi, ; Yoshida, Ido, Sato, Shimazu, & Habukawa, ). According to the 2017 Japanese Guidelines for Childhood Asthma Treatment (JPGL), the aims of daily control include complete control of asthma symptoms, preserving normal lung functions, and achieving an improved quality of life (QOL; Arakawa et al, ). Outpatient asthma management is therefore critically important.…”

Background The objective of this pilot study was to assess the effects of maintaining web‐based diaries by the caregivers of preschoolers with asthma on the adherence to asthma care regimens, the recognition of asthma symptoms, and their perceived levels of parenting stress, quality of life, and family functioning. Design and Methods The caregivers of preschoolers with asthma completed a 4‐week web‐based diary and received weekly emails that depicted their children's asthma symptoms. We compared asthma symptoms from before and after the intervention. We analyzed demographic data, such as the caregivers’ age and education, and assessment scores from the Japanese Pediatric Asthma Control program (JPAC), Adherence with Asthma Management for Caregivers of Preschoolers (AAMCP), General Functioning subscale of the Family Assessment Device (GF‐FAD), Parenting Stress Index Short Form (PSI‐SF), and Quality of Life assessment scale for Caregivers of Asthmatic Children 24 (QOLCA‐24). Results A total of 45 participants were included in the analyses. The mean scores depicting asthma control were significantly improved postintervention (pre: 12.29 ± 2.65; post: 13.02 ± 2.01; t = −2.15, p = .037). Mean AAMCP scores postintervention (52.13 ± 6.25) were significantly greater than before (49.78 ± 7.20; t = −3.07; p = .004). Practice Implications Adherence to asthma care and the recognition of asthma symptoms improved following the use of a web‐based diary, making it a potential cost‐effective intervention for asthma patients and their families.
