<p>Panel A shows the percentage of adolescents in each cohort who report ever having had sex. Panel B indicates the percentage of respondents who reported using a condom at their last sex, amongst those who have ever had sex. Asterisks denote a statistically significant decline between cohorts (two-sided Fisher’s exact test, all significant at level <i>P</i><0.001). Because males were only enroled from the age of 17 in the first two survey rounds, the dashed blued line shows the trend in the proportion of sexually experienced 17 year-old males, and the solid blue line shows the trend for 15 to 17 year-old males in the two most recent rounds.</p
