Association between sleep disturbance and new-onset subjective knee pain in Great East Japan Earthquake survivors: A prospective cohort study in the Miyagi prefecture

ObjectivesThe COVID-19 pandemic has forced many people to stay at home and to maintain social distancing. This study aimed to assess the association of reduced physical activity during the COVID-19 pandemic with new onset of neck pain (katakori) among a rural Japanese population living in areas damaged by the Great East Japan Earthquake (GEJE).Design, setting and participantsThis prospective cohort study has been conducted continuously since 2011 after the GEJE. This study used longitudinal data from 1608 adults who responded to the self-reported questionnaire before and during the COVID-19 pandemic. Changes in physical activity due to the COVID-19 pandemic were categorised into four groups: ‘no change’, ‘decreased by 20%–30%’, ‘decreased by half’ and ‘almost never go out’. Multiple logistic regression analysis was used to estimate the OR and 95% CI of the association between COVID-19 pandemic-related physical inactivity and new-onset neck pain.ResultsIn total, ‘no change’, ‘decreased by 20%–30%’, ‘decreased by half’, and ‘almost never go out’ were reported by 9.2%, 27.7%, 31.2% and 21.9% of respondents, respectively. Among them, 9.8% reported new-onset neck pain. A significantly higher rate of new-onset neck pain was observed in participants who reported ‘decreased by half’ (adjusted OR 1.85, 95% CI 1.04 to 3.30) and who ‘almost never go out’ (adjusted OR 2.13, 95% CI 1.16 to 3.91), compared with those who reported ‘no change.’ConclusionsDecreased physical activity has increased due to the COVID-19 pandemic and was significantly associated with new-onset neck pain among GEJE survivors.

Abstract Background: Anterior knee pain (AKP) is a common limitation to children’s participation in social and physical activities. Therefore, to prevent the occurrence and protraction of AKP, it is crucial to identify risk factors. The purpose of this study was to clarify the factors associated with the occurrence and protraction of AKP in children and adolescents. Method: A three-year prospective cohort study was conducted with children and adolescents aged 8–14 in Japan. We recorded the occurrence of AKP, heel buttock distance, straight leg raising angle (SLRA), dorsiflexion angle of the ankle joint, and the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS). Logistic regression analysis was performed to calculate the odds ratio (OR) for each predicted risk factor for the occurrence and protraction of AKP among subjects without AKP at baseline. Results: We recruited 1,254 children and adolescents for the present study, and 1,133 children and adolescents who did not have AKP at baseline were included in the analysis. Six to nine percent of the subjects developed AKP annually. A high HSS Pedi-FABS score significantly predicted AKP occurrence (in 2017, OR 1.07, 95% CI 1.02−1.12, p = 0.003; in 2018, OR 1.05, 95% CI 1.01−1.10, p = 0.025). Of the participants, 32.9% developed chronic AKP during the follow-up period. When 8-year-old was used as a reference age, 13-year-old subjects (right side, OR 2.37, 95% CI, 1.00−5.61, p = 0.05) and 14-year-old subjects (right side, OR 2.57, 95% CI, 1.00−6.60, p = 0.049; left side, OR 6.32; 95% CI 1.33−30.00, p = 0.020) were at a significantly higher risk of AKP protraction. Conclusions: This study showed that a greater physical activity level was a risk factor for the onset of anterior knee pain in childhood. In addition, one-third of the children and adolescents developed chronic knee pain, and elderly adolescents were at a higher risk of protraction.
