Understanding the relationship between pain and physical activity (PA) levels is beneficial for maintaining good health status. However, the impact of pain on changes in PA during the coronavirus disease 2019 (COVID-19) pandemic is unknown. The purpose of this study was to examine whether PA levels pre-, during, and post-COVID-19 state of emergency differ between Japanese adults who had pain after the COVID-19 state of emergency and those who did not.Data were collected from a cross-sectional online survey conducted between October 19 and 28, 2020. The analytic sample consisted of 1967 Japanese adults aged ≥40 years who completed the online survey. Participants completed questionnaires on the presence of pain and duration of PA, defined as the total PA time per week based on activity frequency and time. Participants were asked to report their PA at 3 time points: October 2019 (before the COVID-19 pandemic), April 2020 (during the COVID-19 state of emergency), and October 2020 (after the COVID-19 state of emergency).Among participants aged ≥60 years who reported pain in October 2020, the total PA time was significantly lower than participants who did not report having pain. Furthermore, the total PA time in April 2020 was significantly lower than that in October 2019; however, no significant difference in total PA time was observed between April and October 2020. Among participants aged 40 to 59 years, no significant differences were observed in total PA times at the 3 time points between those with and without pain. In addition, the total PA time in October 2020 significantly increased compared to that in April 2020, although it significantly decreased in April 2020 compared to October 2019.This study suggests that older adults with pain have lower PA levels after the COVID-19 state of emergency.

Identifying older adults with chronic musculoskeletal pain (CMP) earlier is urgent because CMP is reportedly associated with deterioration in physical function, poor psychological status, and low physical activity level. The objective of this study was to identify factors that were most strongly associated with CMP in Japanese community-dwelling older adults. Using a cross-sectional design, we assessed 263 older adults (mean age=79.1±5.9 years, 85.9% women) who participated in community exercise classes. Participants' physical function, psychological status, and activity levels were evaluated as outcome measures using a variety of tests and instruments. These assessments were conducted prior to beginning the exercise intervention program and compared participants with and without CMP. Additionally, relevant participant characteristics were collected and analyzed. In this study, CMP was defined as the presence of related symptoms within the past month that continued for at least 6 months and corresponded to a numerical rating scale of at least 5 or more at the site of maximum pain. A total of 143 (54.4%) participants met the criteria for CMP, and a high number of them had chronic lower back pain (64.3%). Outcome measures for the CMP group were significantly worse than for the non-CMP group (P, Medicine, 96(23), e7069; 2017
