^*All conceptions of women resident in England and Wales leading to a termination of pregnancy in England and Wales and live or stillbirth (maternities) registered in England and Wales. 

^†Age at time of conception of pregnancy. 

^‡Significant rate increase, P<0.001. Analyses for termination and birth data involved calculating confidence intervals for rate ratios which were subsequently converted to percentage rate increase in 1996 compared with 1995. Analyses of data on sexually transmitted disease used Poisson linear regression with allowance for region effects. 

^§Aggregate data on new diagnoses of sexually transmitted infections diagnosed and reported to the Department of Health and Public Health Laboratory Service by 30 September 1998. 

^¶Numbers of cases of gonorrhoea diagnosed in 16-19 year old men that were attributed to homosexual transmission rose from 31 to 60.
