(MY107) Pregnancy, STDs on the Rise Again Among Teens

THURSDAY, July 16 (HealthDay News) -- Birth rates among U.S. teens increased in 2006 and 2007, following large declines from 1991 to 2005, according to a new U.S. government study.

It found that previously improving trends in teens' and young adults' sexual and reproductive health have flattened or may be worsening in some cases.

U.S. Centers for Disease Control and Prevention researchers analyzed national data from 2002-2007. Among their findings:

About one-third of adolescents hadn't received instruction on methods of birth control before age 18.
In 2004, there were about 745,000 pregnancies among females younger than age 20. This included an estimated 16,000 pregnancies among girls aged 10 to 14.
Syphilis cases among young people aged 15 to 24 have increased in both males and females in recent years.
In 2006, about one million young people aged 10 to 24 were reported to have chlamydia, gonorrhea or syphilis. Nearly one-quarter of females aged 15 to 19, and 45 percent of females aged 20 to 24 had a human papillomavirus (HPV) infection during 2003-2004.
From 1997 to 2006, rates of AIDS cases among males aged 15 to 24 increased.
In 2006, the majority of new diagnoses of HIV infection among young people occurred among males and those aged 20 to 24.
From 2004 to 2006, about 100,000 females aged 10 to 24 visited a hospital emergency department for nonfatal sexual assault, including 30,000 females aged 10 to 14.

"This report identifies a number of concerns regarding the sexual and reproductive health of our nation's young people," Janet Collins, director of CDC's National Center for Chronic Disease Prevention and Health Promotion, said in a news release.


"It is disheartening that after years of improvement with respect to teen pregnancy and sexually transmitted diseases, we now see signs that progress is stalling and many of these trends are going in the wrong direction," she said.


The study also identified a number of racial/ethnic disparities in the sexual and reproductive health of young Americans. For example, Hispanic teens aged 15 to 19 are much more likely to become pregnant (132.8 births per 1,000 females) than non-Hispanic blacks (128 per 1,000) and non-Hispanic whites (45.2 per 1,000). The study also found that non-Hispanic black youth in all age groups have the highest rates of new HIV and AIDS diagnoses.


The study appears in the July 17 issue of the Morbidity and Mortality Weekly Report, published by the CDC

(MY106) World's largest telescope to be built in Hawaii

HONOLULU – Hawaii was chosen Tuesday as the site for the world's biggest telescope, a device so powerful that it will allow scientists to see some 13 billion light years away and get a glimpse into the early years of the universe.

The telescope's mirror — stretching almost 100 feet in diameter, or nearly the length of a Boeing 737's wingspan — will be so large that it should be able to gather light that will have spent 13 billion years traveling to earth. This means astronomers looking into the telescope will be able to see images of the first stars and galaxies forming — some 400 million years after the Big Bang.

"It will sort of give us the history of the universe," Thirty Meter Telescope Observatory Corp. spokesman Charles Blue said.

The telescope, expected to be completed by 2018, will be located atop a dormant volcano that is popular with astronomers because its summit sits well above the clouds at 13,796 feet, offering a clear view of the sky above for 300 days a year.

(MY105) Solar eclipse shrouds Asia

TAREGNA, India – The longest solar eclipse of the 21st century pitched a swath of Asia from India to China into near darkness Wednesday as millions gathered to watch the phenomenon.

But millions more, gripped by fear, shuttered themselves in. India abounds in superstitions and fables based on Hindu mythology, one of which says an eclipse is caused when a dragon-demon swallows the sun.

The eclipse is caused when the moon covers the sun completely to cast a shadow on earth. In some parts of Asia it lasted as long as 6 minutes and 39 seconds.

Thick cloud cover over India obscured the sun when the eclipse began at dawn. But the clouds parted in several cities, minutes before the total eclipse took place at 6.24 a.m. (0054 GMT; 8:54 p.m. EDT).
