question: Social isolation and loneliness are associated with morbidity and mortality and highly prevalent in older adults Older adults, a high-risk group for developing serious complications from COVID-19, are asked to shelter-in-place limiting physical interactions We aimed to determine the effect of the COVID-19 pandemic on social isolation and loneliness among community-dwelling older adults previously enrolled in in-person exercise classes in the Leveraging Exercise to Age in Place (LEAP) study before March 19th, 2020 when California started shelter-in-place We conducted a pre-post analysis of cognitively intact participants (n=59) &amp;gt;50 years, who had social connectedness, loneliness, and demographic data collected pre- and post-COVID shelter-in-place Participants’ social connectedness was measured via the 11-question Duke Social Support Index (DSSI) and loneliness via the 3-question UCLA Loneliness Scale (UCLA 3) Participants had an average (±SD) baseline DSSI of 27 2 (± 3 5) and UCLA 3 of 4 8 (± 1 7) and were an average of 76 6 ± 9 2 years, 81% female, 63% white, 29% widowed, 42% living alone, 27% acting as caregivers, and 44% were diagnosed with 3 or more chronic health conditions We completed post-assessments on average 61 ± 29 days after the start of shelter-in-place Results of the paired t-tests indicated no statistically significant difference in social connectedness and loneliness pre- and post-shelter-in-place Reasons for lack of observed change include: limitations of a small sample size, possible protective factors from enrollment in the LEAP program, or insufficient time at post-assessment to develop changes in loneliness and social isolation Repeated assessments are needed throughout the pandemic
