  9. America in the 70s • Make love, not war • Abortion becomes legal • Contraception widely available • Title X family planning funds • Gonorrhea control funds

  10. Legal and Illegal Abortions in the US, 1969 to 1980 Abortions (millions) Source: Cates (1982)

  11. Maternal Mortality and Abortion Mortality in the US, 1940-1980 Source: US Vital Statistics, National Center for Health Statistics

  12. Abortion Morbidity - JPSA • Partnership of Population Council and CDC • Cohort study of abortion procedures and complications • >230,000 procedures performed from 1970-1978 • 66 participating facilities, including the University of Pittsburgh

  13. Abortion Morbidity – Key Findings • 57 original contributions • Suction curettage safer than sharp curettage • Non-hospital procedures safe • Dilatation and evacuation after 12 weeks gestation safer than intra-amniotic instillation

  14. Trends in Abortion Procedures, 1972-1994 Source: CDC Annual Abortion Surveillance Summaries

  15. The Trimester Threshold – 1975 16 15 14 13 Actual distribution (with delay for instillation) 12 11 10 9 Abortions (% of total 8 Projected distribution (without delay) 7 6 Decrease in later abortions if no delay 5 4 3 Increase in earlier abortions if no delay 2 1 0 10 11 12 13 14 15 16 17 18 19 20 Menstrual weeks’ gestation

  16. D&E Safer than Instillation

  17. Effect of D&E on Women’s Health • Since 1977, more than 1.8 million women have been spared instillation • Earlier procedures • Safer procedures • More convenient • Less costly • Less emotionally traumatic

  18. Abortion and Public Health - Conclusion • Availability of safer, legal abortion had a major impact on women’s health and public health • However, abortion had a negligible effect on population change • Data do NOT address society’s moral problem with this topic

  19. Enter THE Virus

  20. “Anyone who has the least ability to look into the future can already see the potential for this disease being much worse than anything mankind has seen before.” Ward Cates Newsweek, August 12, 1985 Total Number of AIDS Cases – 12,067

  21. America in the ’80s and ’90s • HIV/AIDS as domestic/global priority • New PH Issues – Tobacco, Injuries, Chronic Diseases, Mental Health • Increasing emphasis on women’s health • Incorporation of HIV into RH mission – Cairo ICPD, 1994

  22. Spermicides as Microbicides Source: Advances in Planned Parenthood. Vol 12 #1, Amsterdam Excerpta Medica, 1977:45-56

  23. Spermicides as Microbicides -The Nonoxynol-9 Story • In vitro success – Anti-sperm membrane – Anti-microbial membranes • FDA approval • Long contraceptive history

  24. Evolution of N-9 Microbicidal Research • Initial hopes against bacterial STD • Observational findings • Sponge protects from Gc, though hint of higher HIV risks • Epithelial toxicity concerns

  25. N-9 Film - Effect on HIV Acquisition No. of HIV No. of HIV incidence RR women infections 100 p-y (95% CI) Placebo 575 46 6.6 1.0 Film N-9 Film 595 48 6.7 1.01 (0.68-1.52) Source: Roddy, NEJM 1998

  26. Topical Microbicides – Lessons from N-9 HIV Trials • HIV incidence in trials compared to the community • Value of RCT compared to observational designs • Difficulties in etiologic reasoning between active arm and placebo

  27. Reanalysis of Cameroon N-9 Observational Study • Data Source: Coital diaries from sex workers • Measure: Efficacy per sexual episode • Result: Condoms 92% (79-100%) • N-9 Suppositories 100% (43-100%) Sources: Zekeng (1993), Wittkowski (1998)

  29. Observational vs. Experimental Analysis Same N-9 Study of Cameroon Sex Workers • Roddy Roddy • Analysis Observational Experimental • Rates of HIV: • Inconsist 15.6 Placebo 4.3 • Consistent 5.0 N-9 5.3 • Rate Ratios 0.3 (0.1-0.7) 1.2 (0.7-2.1) • Source: Roddy (1998)

  30. America in the New Millennium • HIV as THE global health priority • Global warming/the environment as a global emergency • Population growth a major factor

  31. World Population, 2007 • Population projections lowered substantially • Half due to reduced fertility rates • Half due to increased mortality from AIDS • BUT global population will still rise by 2.5 billion persons Source: UN Population Division (2007)

  38. Population and Environment - 2007 • World is growing by 78M annually • Levels of consumption increasing as disparities reduced • Like HIV, the environment needs an infusion of billions to improve • Unintended pregnancy the factor most amenable to interventions • Strengthening RH services is crucial to slowing rates Source: Speidel (2007)

  39. How to Proceed? • A vision for Sexual Health

  40. Underlying Foundation for Sexual Health • “Absence of Disease” • – Old Millennium • – Negative Message • Healthy Sex • – New Millennium • – Positive Message
