Study Shows Teen Contraception Use Declining, Level Of Sexual Activity Unchanged
After years of declining teenage pregnancy rates and improved teen contraception use during the 1990s and early 2000s, the trends appeared to have flattened or even reversed among some groups of teens in recent years, according to a study from Columbia University"s Mailman School of Public Health and the Guttmacher Institute, the Christian Science Monitor reports. Researchers found that from 2003 to 2007, teens" contraceptive use declined by 10%, while their level of sexual activity did not change. The decrease in contraceptive use was particularly prevalent among black teens. The figures take into account the rate of contraception use as well as the types of contraceptives used, as methods vary in effectiveness. Teen condom use leveled off and in some cases declined, according to the study. The study also reported that the teen birth rate increased by 5% from 2005 to 2007. According to the study"s authors, the findings suggest a link between declining teen contraception use and the rise in abstinence-only education during former President George W. Bush"s administration. President Obama"s fiscal year 2010 budget proposal calls for redirecting some abstinence-only funds toward increased comprehensive sex education, the Monitor reports. In addition to the effects of abstinence-only sex education, the decline in condom use also could be tied to lessening concern about sexually transmitted infections, including HIV/AIDS. A shift in the teen population to include a higher number of Hispanics -- who have the highest rates of teen pregnancy and birth -- also could contribute to the findings. Laura Lindberg, one of the study"s authors and a senior research associate at Guttmacher, said, "In the end, this story is really about the loss of momentum." She added that although the statistical changes are small, "they raise concern about what the next few years will bring in this country." Sarah Brown, director of the National Campaign To Prevent Teen and Unplanned Pregnancy, noted that the proportion of births to unmarried women, particularly among women ages 20 to 24, also is on the upswing (Feldmann, Christian Science Monitor, 6/18).

Gathering Of Swine Flu Experts At New York Academy Of Sciences May 28

The very latest information on the 2009 swine influenza (H1N1) outbreak is the subject of a landmark afternoon symposium hosted by the New York Academy of Sciences today, Thursday, May 28. Speakers will discuss the new recombinant virus, epidemiology, treatment, vaccine development and the public health implications of a worldwide pandemic. Reservations are required to attend the conference, held from 12:30 p.m. to 5:30 p.m., at academy offices, 7 World Trade Center, 40th floor, 250 Greenwich St. at Barclay St. A reception will follow. Two microbiologists/immunologists from New York Medical College are leading the symposium, which will focus on understanding the pathogenicity and transmission of the viruses to develop improved methods of prevention and control. Keynote speaker Edwin D. Kilbourne, M.D., emeritus professor, developed the first genetically engineered vaccine of any kind more than 30 years ago. He is an internationally recognized research scientist who has made significant contributions to the study and prevention of influenza and other viral diseases. Doris Bucher, Ph.D., associate professor, whose laboratory in Valhalla is one of just three worldwide that reproduces "seed" viruses for the influenza vaccine, which begins the process of producing some 450 million doses of a new vaccine each year. Dr. Bucher is the symposium organizer. Speakers include Michael Shaw, CDC Influenza Division; Dominick A. Iacuzio, Hoffman-La Roche, Inc.; Kanta Subbarao, NIH Laboratory of Infectious Diseases; John Treanor, University of Rochester School of Medicine and Dentistry; Philip R.
