“…4,5 These rates are in keeping with the increasing overall prevalence of DM among adults, and with recent studies from nursing homes in the United States that have reported DM prevalence of as high as 34%. 6,8,9 Our study evaluated DM prevalence rates over a 5 year period (which included the years of the COVID-19 pandemic) and did not find any substantial variation in prevalence rates during this time overall or by sex (Figure 1), despite a significant decline in nursing home occupancy likely due to high mortality during the peaks of waves of the pandemic. However, we observed regional variability in the prevalence of DM in Ontario nursing homes that is consistent with higher rates in more central, urban regions which also have higher rates of ethnic diversity (see Supplemental Material Figure S1).…”
