BackgroundStudies have shown that there is a certain relationship between smoke exposure and constipation. There are limited data on the associations between constipation and smoking or serum cotinine levels, a metabolite of nicotine commonly used as a marker of tobacco exposure. MethodsIn this study, we thoroughly examined the cross-sectional data from the NHANES from 2005 to 2010. To assess the associations between tobacco smoking status, serum cotinine levels and constipation, multivariate logistic regression models were applied. ResultsIn this cross-sectional study, 11651 participants were included. The average age of the participants in the research was 48.8±17.9 years. After controlling for covariates, there was no significant relationship between levels of serum cotinine levels, smoking status and constipation risk. According to the categorical analysis, the incidence of constipation was 36% higher in participants with serum cotinine levels between 0.05-2.99 ng/mL (model 1: OR=1.45 [1.13-1.85]; model 2: OR=1.44 [1.12-1.83]; model 3: OR=1.36 [1.06-1.74]; P<0.05) after adjusting for covariates by using the lowest levels of serum cotinine (<0.05 ng/ml) as a reference. In the nonsmokers, serum cotinine levels were linearly and positively associated with the risk of constipation (P nonlinearly > 0.05), and the relationship between smoke exposure and constipation was relatively stable in each subgroup.ConclusionThe promoting effect of serum cotinine levels on stool frequency-related constipation occurs in nonsmokers. Therefore, avoiding passive smoking as much as possible may reduce the effect of smoke exposure on constipation, as well as prevent and treat constipation.
