ObjectivesThis study aimed to assess the relationship between sleep duration on work or non-workdays and myocardial infarction (MI) and stroke in Southern China.MethodsA cross-sectional survey was conducted among 15,364 participants ≥15 years in Southern China from November 2013 to August 2014. Self-reported duration of sleep on workdays or non-workdays, history of MI and stroke were conducted by the questionnaire. The subjects were examined with weight, height, waist circumference, blood pressure. Multivariate logistic regression analyses were performed to evaluate sleep duration with MI and stroke.ResultOverall, compared with sleep duration of 6-8 h, individuals who slept <6h on workdays and non-workdays were associated with increased risk of MI (OR = 3.17, 2.04). Still, individuals who slept >8 h on workdays and non-workdays were associated with increased risk of stroke (OR = 1.86, 1.54). Although this association persisted in men or subjects aged <65 years. We also observed long sleep duration on workdays associated with MI, especially among women and short sleep duration on non-workdays associated with stroke among those aged 65 years or older. Participants in the abnormal sleep duration and with hypertension had the higher risk of MI and stroke. Sleep debt was independently associated with MI risk, not stroke (OR = 1.40; 95%CI: 1.06-1.86), specifically among men aged <65 years.ConclusionsCompared with sleep duration of 6-8 h, short and long sleep duration were both associated with prevalent MI and stroke and these associations were more pronounced among hypertensive persons and tended to vary by age and sex. Moreover, sleep debt linked to greater MI risk among men aged <65 years. These findings suggest we should develop a healthy biological clock.
