To examine the association between time to first cigarette (TTFC) after waking and hypertension in males.
The baseline data of 587 male current smokers in Rongchang district were collected from the China Multi-Ethnic Cohort(CMEC) Study in Rongchang. The association between TTFC after waking and hypertension was conducted by multivariate logistic regression.
TTFC ≤5 minutes, 6-30 minutes, 31-60 minutes and > 60 minutes accounted for 34.24%, 26.75%, 16.70% and 22.31%. The prevalence of hypertension among 587 participants were 59.20%, 40.76%, 35.71%, 29.01%. Compared with TTFC>60 min after waking, TTFC<5min(OR=3.691, 95% CI: 2.176-6.259) and 6-30 min(OR=1.876, 95% CI: 1.236-2.911) were risk factors of hypertension after adjusting for confounding factors.
The short TTFC after waking is associated with a higher risk of hypertension. It is helpful to evaluate the risk of hypertension and make targeted smoking cessation plan according to TTFC.
