A research group led by Takenori Inomata, an associate professor of ophthalmology at Juntendo University Graduate School of Medicine, conducted a large-scale cloud-type clinical study using the iPhone app "Allersearch ® ︎". We clarified the characteristics of people with hay fever and the characteristics related to the intensity of hay fever symptoms.
In this research, 2018 people who downloaded the iPhone application "Aller Search ®" using Apple's Research Kit during the target period (February 2, 1 to May 2020, 5) and obtained consent were targeted. And said.
The severity of hay fever is evaluated on a scale of 4 using a 5-item nasal symptom score with a maximum of 4 points and a non-nasal symptom score with a 36-point scale. Examine information, history, lifestyle, presence or absence of hay fever, and characteristics of people with hay fever and characteristics related to the intensity of hay fever symptoms.In addition, we investigated preventive actions taken against pollinosis.The median age of study participants was 34 years (interquartile range 23-46 years), with 56.4% being female.The residential areas are 2,510 (22.2%) in Tokyo, 1,070 (9.5%) in Kanagawa, and 957 (8.5%) in Osaka.Of the 11,284 study participants, 80.1% (9,041) had a history of pollinosis.
The characteristics of people with hay fever were "young age, women, atopic dermatitis, dry eye, interruption of contact lens wearing during the hay fever season *, frequent defecation, and short sleep time".Furthermore, as characteristics related to the intensity of hay fever symptoms, "young age, women, respiratory diseases, dry eye, tomato allergy, discontinuation of contact lens wearing during the hay fever season *, smoking habits, pet breeding" became clear. rice field.
By further researching, we aim to develop a smartphone app that can manage the symptoms of pollinosis, suppress its aggravation, and prevent / treat it, and it will be a driving force for promoting prediction / prevention / individualization / participatory medical care by future smartphone apps. Be expected.
* This analysis looks at the correlation between the two, and does not show a causal relationship.For example, there was an association between discontinuation of contact lenses during the hay fever season and the intensity of hay fever symptoms, but the increased hay fever symptoms may result in discontinuation of contact lens wear during the hay fever season. ..Therefore, it is not recommended to continue wearing contact lenses during the hay fever season to prevent exacerbation of hay fever symptoms.
