Abstract P166: The Joint Secular Trends Of Sleep Quality And Diabetes Among The US Adults

Abstract

Introduction: Despite the extensive efforts in controlling diabetes-related modifiable risk factors, two recent studies showed that the estimated prevalence of diabetes in the U.S. has still increased in the past two decades. The sleep quality has been related to the risk of diabetes. Hypothesis: We examined the secular trends of the overall sleep quality, and the joint trends in the prevalence of diabetes by the overall sleep quality among US adults from 2005 to 2018. Methods: A total of 17,046 participants aged 20 years or older, from seven cycles of National Health and Nutrition Examination Survey (NHANES) data between 2005 to 2018, were eligible for the study. A healthy sleep score was calculated based on sleep 7-8 hours, no trouble sleeping, no snoring, no nocturia and no excessive daytime sleepiness to represent an overall sleep quality. The trends in estimated prevalence of diabetes were examined in different sleep quality groups. Results: From 2005 to 2018, the overall sleep quality significantly declined among US adults ( P for trend<0.001). Both the estimated age-standardized prevalence of diabetes and changing trend in prevalence of diabetes varied by the overall sleep quality groups. The highest prevalence of diabetes was consistently observed in the low sleep quality group in each cycle, in which a significantly increasing trend was also noted across cycles ( P for trend=0.004). In contrast, the lowest prevalence of diabetes was consistently observed in the high sleep quality group in each cycle, in which no increasing trend over time was observed ( P for trend=0.346). Such differential secular trends by sleep quality were more significant among Non-Hispanic Whites than other racial/ethnic minorities. Conclusions: The overall sleep quality decreased significantly between 2005-2018 in U.S. adults. The estimated prevalence of diabetes only increased in participants with low or medium overall sleep quality but remained stable in participants with high sleep quality.
