This study surveyed adult web monitor enrollees about the lives of and stress experienced by Japanese children and adolescents during the prolonged coronavirus disease 2019 (COVID-19) pandemic. The survey was conducted on February 10, 2022 (after the sixth wave) and August 19, 2022 (during the seventh wave of the COVID-19 pandemic in Japan), with 231 and 217 survey participants, respectively. The questionnaire was designed so that adults could assess the frequency of exercise, and difficulties experienced by children and adolescents around them. Regarding exercise opportunities, 22% of parents of middle and high school children reported that children’s exercise opportunities “stayed the same” or “increased considerably” in the first survey. Whereas, in the second survey, all parents of middle and high school children reported that children’s exercise opportunities “decreased.” Regarding stress, 17% of parents of adolescents 18 years and older responded that the stress experienced was the “same as before” or “a little less than before” in the first survey, but all of these parents responded “quite a bit” to the same question in the second survey. The findings suggest that the life changes caused by the COVID-19 pandemic may have a significant impact on children and adolescents and may increase stress. The long-term effects of the COVID-19 pandemic on children and adolescents should be further investigated.
