seventy years old. With adjustments for self-reported circadian rhythm and age, questionnaires were used to estimate the autism spectrum quotient (AQ), empathy quotient (EQ), and systemizing quotient (SQ) among research participants. The participants answered the composite morning questionnaire (CSM) to determine circadian rhythms.
Individuals recorded their own axillary temperatures, temperature recording times, wake-up times, and the axillary thermometer’s manufacturing information. The participants also recorded factors that can alter body temperature, such as the presence of a cold, taking temperatures after exercise, taking antipyretic drugs, and getting vaccinated against the coronavirus the week before.
Information on the participants’ Data were collected for 3,227 and 3,402 persons, respectively, spread throughout 47 prefectures in Japan, for surveys one and two.
Data from 827 and 1,020 participants, respectively, were eliminated because they were collected using questionable methods and tried-and-true methods.
In order to determine the relationship between ASD and body temperature, data were evaluated for 2,185 and 2,264 individuals, respectively, whereas 2,211 and 2,288 individuals were used for the other connections.
