a - OR indicates odds ratios; CI-L and CI-U indicates lower and upper confidence intervals respectively; Bolded indicates significant results at p ≤ 0.05

' - ' in an OR cell indicates this variable was not applicable and therefore not used for the particular age group

Variables included but not significant in any regression: age, school attendance, marital status, work status, and birth control use
