Among the 4976 women with completed follow\u2010up to delivery, GDM was detected in 23.1% (\n                      <jats:italic>N<\/jats:italic>\n                      = 1151) according to the Finnish National Current Care Guidelines. Adjusted logistic regression analyses (controlling for maternal age, body mass index [BMI], smoking, physical activity, and gestational weight gain) were used to examine the associations between sleep disturbances and GDM.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Difficulty falling asleep (aOR 1.35; 95% CI 1.05\u20131.72), nighttime or early morning awakenings (aOR 1.16; 95% CI 1.00\u20131.34), and frequent (aOR 1.21; 95% CI 1.02\u20131.44) and daily daytime sleepiness (aOR 1.52; 95% CI 1.14\u20132.03) remained significant risk factors for GDM after adjusting for covariates. Furthermore, the risk of GDM increased in a linear manner with the number of reported sleep disturbances (aORs 1.07\u20131.41). A higher first\u2010trimester BMI was the strongest predictor of experiencing multiple sleep disturbances. Among women with GDM, sleep problems were more frequent in those requiring pharmacological treatment compared with those managed with lifestyle interventions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Sleep disturbances are strongly associated with the development of GDM.
