ABSTRACT
Objective@#To investigation the correlation between sleep duration and hypertension among adults in Zhejiang Province, and to provide scientific evidence for the prevention and control of hypertension.@*Methods@#Permanent residents at age of 18 years and older were enrolled from 10 surveillance sites for risk factors of chronic diseases included in the 2018 China Chronic Diseases and Risk Factors Surveillance Program. Subjects' demographic characteristics, smoking, alcohol consumption, sleep duration and development of hypertension were collected, and following complex weighting calculations, the association between sleep duration and hypertension were examined using a multivariable logistic regression model.@*Results@#Totally 5 770 adults were included, including 2 952 men (50.72%) and 3 178 women (49.28%), and the prevalence of hypertension was 29.39% (2 702 cases). There were 712 (8.37%), 1 077 (18.77%), 1 582 (28.68%), 1 717 (34.60%) and 682 adults (9.57%) with sleep duration of <6 h/d, 6 to 7 h/d, 7 to 8 h/d, 8 to 9 h/d and 9 h/d and longer, respectively. Taking the sleep duration of 7 to 8 h/d as a reference, multivariable logistic regression analysis identified a significant association between sleep duration of <6 h/d and the risk of hypertension (OR=1.709, 95%CI: 1.184-2.466), a significant association between sleep duration of 9 h/d and longer and the risk of hypertension (OR=1.369, 95%CI: 1.006-1.862) in men, significant associations between sleep duration of <6 h/d (OR=2.174, 95%CI: 1.528-3.093) and 6 to 7 h/d (OR=1.412, 95%CI: 1.078-1.850) and the risk of hypertension in women, and significant associations between sleep duration of <6 h/d (OR=3.095, 95%CI: 1.025-9.347) and 6 to 7 h/d (OR=2.046, 95%CI: 1.156-3.622) and the risk of hypertension in residents at ages of 18 to 44 years.@*Conclusions@#Short sleep duration may increase the risk of hypertension among adults at ages of 18 to 44 years in Zhejiang Province. Short sleep duration may increase the risk of hypertension in women and long sleep duration may increase the risk of hypertension in men.
ABSTRACT
Objective@#To analyze the trends in incidence and mortality of Alzheimer's disease (AD) in Zhejiang Province from 2003 to 2017, so as to provide the evidence for the development of AD prevention and control strategies. @* Methods@#The data pertaining to the incidence and mortality of AD in China from 2003 to 2017 were collected from the Global Burden Disease Study, and standardized to the data of the Sixth National Population Census in China in 2010. The trends in incidence and mortality of AD were analyzed using annual percent change (APC) and average annual percent change ( AAPC ) in Zhejiang Province from 2003 to 2017. @*Results@#The incidence of AD increased from 96.05/105 in 2003 to 140.96/105 in 2017 in Zhejiang Province, with AAPC of 2.776% ( P<0.05 ), and the greatest APC ( 3.419% ) was found during the period between 2003 and 2005 ( P<0.05 ). The standardized incidence of AD increased 102.06/105 in 2003 to 106.09/105 in 2017 in Zhejiang Province, with AAPC of 0.274% ( P<0.05 ), and the greatest APC ( 1.177% ) was measured during the period between 2003 and 2005 ( P<0.05). The mortality of AD increased from 24.60/105 in 2003 to 41.44/105 in 2017 in Zhejiang Province, with AAPC of 3.862% ( P<0.05 ), and the greatest APC (4.667%) was found during the period between 2005 and 2011 ( P<0.05 ). The standardized mortality of AD increased 26.83/105 in 2003 to 27.16/105 in 2017 in Zhejiang Province, with AAPC of 0.142% ( P>0.05 ), and the greatest APC ( 1.048% ) was measured during the period between 2005 and 2012 ( P<0.05 ).@*Conclusion@#Both the incidence and mortality of AD appeared a tendency towards a rise in Zhejiang Province from 2003 to 2017.
