We used multivariate logistic regression models to report odds ratios (OR) and 95% confidence intervals (CI).Results: Among 9264 participants, 33.7% had metabolic syndrome, and 37.6% had ever smoked waterpipe, with both more common in women than in men. In adjusted models, former waterpipe use was significantly associated with prevalence (OR=1.43, 95%CI:1.23-1.68) and incidence (OR=1.57, 95%CI:1.19-2.06) of the metabolic syndrome while current waterpipe use was not. Past use was associated with increased risk in all components of metabolic syndrome; current use was associated with increases in all except high blood glucose and hypertension. Waterpipe use was associated with metabolic syndrome and its components, especially among former users potentially due to higher intensity and earlier initiation of use.
