The association between smoking and dizziness in U.S. adults: a population-based survey study

Abstract

Objective Smoking is a risk factor for several conditions associated with dizziness, such as cardiovascular disease and emphysema. However, little is known about the specific association between smoking and dizziness. The purpose of this study was to examine the relationship between smoking and dizziness in the U.S. adult population. Methods Responses from the 2008 National Health Interview Survey of U.S. adults (n = 21,781) were used to identify risk factors for dizziness and smoking. Results Of the 21,781 adults in the survey, 41.8% smoked more than 100 cigarettes in their lifetime. Of the 2,490 adults who had a self-diagnosed problem with dizziness, 54.1% had smoked more than 100 cigarettes in their lifetime. This corresponded to an odds ratio of 1.72 (95% CI, 1.56–1.89; p < .001) for experiencing dizziness with a history of smoking. In a multivariate analysis that included prior lung disease, cardiovascular disease, diabetes, hypertension, prior stroke, head trauma, age, sex, anxiety, depression, and history of migraines, smoking remained a significant risk factor for dizziness (OR 1.30; 95% CI, 1.17–1.46; p < .001). Conclusion In a representative nationwide survey of U.S. adults, smoking is independently associated with dizziness, even after controlling for demographic variables, known risk factors for dizziness, and smoking related diseases.
