We aim to evaluate the dynamics of CGM accuracy during exercise in patients with T1D. Secondary analysis of data was carried out on 22 patients with T1D (glycated hemoglobin [HbA\n                    <jats:sub>1c<\/jats:sub>\n                    ]: 7.3%\u2009\u00b1\u20091.0%, diabetes duration: 23\u2009\u00b1\u200913 years), who did three exercise sessions (45\u2009min at 60% VO\n                    <jats:sub>2max<\/jats:sub>\n                    on an ergocycle, 3\u2009h postmeal) with paired Dexcom G4 Platinum, and capillary glucose values that were collected every 5\u2009min. Dexcom accuracy was evaluated using sensor bias (SB) and absolute relative difference (ARD). For dynamics of SB analysis, data pairs following hypoglycemia correction were excluded. The analyzed data included 792 pairs (594 during 66 exercise sessions, 198 at rest before exercise). Median ARD was 8.44 (5.35\u201312.13)% at rest and increased to 16.77 (10.75\u201326.72)% during exercise (\n                    <jats:italic toggle=\"yes\">P &lt;<\/jats:italic>\n                    0.001). During exercise, mean SB values evolved from T0 minutes\u2009=\u20095.95\u2009\u00b1\u200916.04\u2009mg\/dL (exercise start); T5\u2009=\u20099.55\u2009\u00b1\u200916.40; T10\u2009=\u200913.51\u2009\u00b1\u200918.02; T15\u2009=\u200915.32\u2009\u00b1\u200920.36; T20\u2009=\u200917.30\u2009\u00b1\u200918.92; T25\u2009=\u200919.46\u2009\u00b1\u200917.48; T30\u2009=\u200921.08\u2009\u00b1\u200919.64; T35\u2009=\u200919.10\u2009\u00b1\u200920.36; T40\u2009=\u200919.82\u2009\u00b1\u200920.18; and T45\u2009=\u200918.02\u2009\u00b1\u200920.90 (exercise end). CGM overestimated capillary at a mean SB of 14.23\u2009\u00b1\u200916.76\u2009mg\/dL over the whole exercise session. CGM accuracy decreased during moderate aerobic exercise as previously described. However, the trend to overestimate capillary glucose was maintained at relatively stable values within 15\u2009min of exercise initiation, which could help patients in their clinical decisions. Similar analyses would be needed for other types of exercise.\n                  <\/jats:p>","DOI":"10.1089\/dia.2018.0400","type":"journal-article","created":{"date-parts":[[2019,5,2]],"date-time":"2019-05-02T11:56:23Z","timestamp":1556798183000},"page":"364-369","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Changes in Accuracy of Continuous Glucose Monitoring Using Dexcom G4 Platinum Over the Course of Moderate Intensity Aerobic Exercise in Type 1 Diabetes"],"prefix":"10.1177","volume":"21","author":[{"given":"St\u00e9phanie","family":"Larose","sequence":"first","affiliation":[{"name":"Metabolic Diseases, Institut de Recherches Cliniques de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u00e9mi","family":"Rabasa-Lhoret","sequence":"additional","affiliation":[{"name":"Metabolic Diseases, Institut de Recherches Cliniques de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."},{"name":"Nutrition Department, Faculty of Medicine, Universit\u00e9 de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."},{"name":"Montreal Diabetes Research Center and Endocrinology Division, Montr\u00e9al, Qu\u00e9bec, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Am\u00e9lie","family":"Roy-Fleming","sequence":"additional","affiliation":[{"name":"Metabolic Diseases, Institut de Recherches Cliniques de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corinne","family":"Supp\u00e8re","sequence":"additional","affiliation":[{"name":"Metabolic Diseases, Institut de Recherches Cliniques de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9mah","family":"Tagougui","sequence":"additional","affiliation":[{"name":"Metabolic Diseases, Institut de Recherches Cliniques de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virginie","family":"Messier","sequence":"additional","affiliation":[{"name":"Metabolic Diseases, Institut de Recherches Cliniques de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadine","family":"Taleb","sequence":"additional","affiliation":[{"name":"Metabolic Diseases, Institut de Recherches Cliniques de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."},{"name":"Division of Biomedical Sciences, Faculty of Medicine, Universit\u00e9 de Montr\u00e9al, Montr\u00e9al, Qu\u00e9bec, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,5,22]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/193229681100500419"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.d3805"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD008101.pub2"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.2337\/dc15-0078"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/s16122093"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2016.19975"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/pedi.12711"},{"key":"e_1_3_5_9_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-157-5-201209040-00508"},{"key":"e_1_3_5_10_2","doi-asserted-by":"publisher","DOI":"10.1530\/EJE-11-0642"},{"key":"e_1_3_5_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1262-3636(07)70285-9"},{"key":"e_1_3_5_12_2","doi-asserted-by":"publisher","DOI":"10.1089\/dia.2012.0182"},{"key":"e_1_3_5_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.diabres.2015.11.012"},{"key":"e_1_3_5_14_2","doi-asserted-by":"publisher","DOI":"10.1089\/dia.2015.0394"},{"key":"e_1_3_5_15_2","doi-asserted-by":"publisher","DOI":"10.1089\/dia.2011.0052"},{"key":"e_1_3_5_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.2011.02390.x"},{"key":"e_1_3_5_17_2","first-page":"S1262","article-title":"Timing of insulin basal rate reduction to reduce hypoglycemia during late post-prandial exercise in adults with type 1 diabetes using insulin pump therapy: a randomized crossover trial","author":"Roy-Fleming A","year":"2018","unstructured":"Roy-Fleming A, , Taleb N, , Messier V, et al.: Timing of insulin basal rate reduction to reduce hypoglycemia during late post-prandial exercise in adults with type 1 diabetes using insulin pump therapy: a randomized crossover trial.
