Notes:
Abbreviations: P12M = past 12-month; W2 = Wave 2; W3 = Wave 3; W1 = Wave 1; polytobacco use = PTU; w/ = with; CIGS = cigarettes; w/o = without; CI = confidence interval
Analysis included youth (ages 12–17), young adult (ages 18–24), and adult 25+ (ages 25 and older) W1 P12M hookah users with data at all three waves. Respondent age was calculated based on age at W1. W3 longitudinal (all-waves) weights were used to calculate estimates. All tobacco use is defined as P12M use. Use type refers to exclusive use, PTU w/CIGS, or PTU w/o CIGS.
denotes significant difference at p<0.0167 (Bonferroni corrected for three comparisons) between W1 Exclusive Hookah Use and W1 Hookah PTU w/CIGS
denotes significant difference at p<0.0167 (Bonferroni corrected for three comparisons) between W1 Exclusive Hookah Use and W1 Hookah PTU w/o CIGS
denotes significant difference at p<0.0167 (Bonferroni corrected for three comparisons) between W1 Hookah PTU w/CIGS and W1 Hookah PTU w/o CIGS
The logit-transformation method was used to calculate the 95% CIs.
Estimate should be interpreted with caution because it has low statistical precision. It is based on a denominator sample size of less than 50, or the coefficient of variation of the estimate or its complement is larger than 30%.
Analyses were run on the W1, W2, and W3 Public Use Files (https://doi.org/10.3886/ICPSR36498.v8).
