Abstract
Introduction: We aimed to explore the association between night sleep duration and ideal cardiovascular health (ICH) among Chinese rural population.Methods: In all, 35,094 participants were included from the Henan Rural Cohort study. Information on sleep was collected using the Pittsburgh Sleep Quality Index. The ICH scores were evaluated. The associations between night sleep duration and ICH were examined using both linear regression and logistic regression models.Results: The mean night sleep duration for all participants was 7.75 ± 1.28 h. Compared with those with night sleep duration of 7 to <9 h by using linear regression model, a significant decrease in ICH scores was observed for participants with shorter [−0.077 (−0.131, −0.024)] and longer [−0.079 (−0.121, −0.036)] night sleep duration. Compared with 7 to <9 h, longer sleep duration [0.919 (0.851, 0.992)] were associated with decreased odds of ideal CVH.Conclusions: Shorter and longer night sleep duration are negatively associated with ICH among rural population. This suggests that it may be beneficial to include night sleep duration assessment in cardiovascular risk screening.
Highlights
We aimed to explore the association between night sleep duration and ideal cardiovascular health (ICH) among Chinese rural population
A strong association between longer night sleep duration and ICH metrics was observed in physical activity and blood pressure
There was a strong correlation between shorter night sleep duration and ICH metrics including total cholesterol, body mass index (BMI) and smoking, and a strong association between longer sleep and ICH metrics was observed in physical activity and blood pressure
Summary
We aimed to explore the association between night sleep duration and ideal cardiovascular health (ICH) among Chinese rural population. Cardiovascular disease (CVD) is the leading cause of premature mortality and disability both worldwide [1, 2] and in China [3]. Prospective studies consistently indicated that individuals with higher number of ICH metrics have lower risks of CVD events, hypertension, type 2 diabetes mellitus, cancer and all-cause mortality [6,7,8,9,10,11]. In the past few years, several studies have evaluated the relationship between night sleep duration and the occurrence of hypertension [12], diabetes [13], CVD [14,15,16,17,18].
