*Significance determined at α=0.05, and p values produced via Student’s t-test, χ2 test for homogeneity, or Fisher’s exact test. Those with missing information on variables or whose self-reported gender was other than girl/boy were not used in the statistical comparisons.
†Types of sexual acts are overlapping categories causing the sum total to exceed the number of sexually active youth. Column percentages represent the marginal proportions.
