A study conducted by researchers at Brown Medical School in Providence, RI, has revealed that many teenagers and young adults fail to use condoms consistently, regardless of whether they have sex with a serious or a "casual" partner. The research, which included 1,316 15- to 21-year-olds from three large U.S. cities, showed that most of the young people had unprotected sex with casual partners as often as those in serious relationships. The figures are, on average, about 20 times over the previous three months.

"Unfortunately, this reveals that teens may overestimate the safety of using condoms most of the time with a casual partner and underestimate the risk of unprotected sex with a serious partner," lead study author Dr. Celia Lescano said in a statement.

New York, NY (AHN)-New data suggests that women who have undergone a successful surgery to repair congenital heart defects can become pregnant, but they may have clinically significant complications.

Until recently, pregnancy was discouraged in women who have undergone the so-called "Fontan operation," named after the developer of the procedure, to correct complex birth defects of the heart. However, case reports and one clinical study suggests that women can become pregnant and deliver healthy infants.

A new study suggests that children of alcoholic parents could become addicts themselves. In addition, they may undergo emotional, behavioral and mental problems.

A new study in the U.K. has found that applying make-up regularly could be hazardous to health. The study says that on average a woman applies 175 chemicals on a daily basis categorized as cosmetics and toiletries.

Of those chemicals, most are mixes of various chemicals that are associated to health problems. In fact, some of those chemicals are linked to cancer, hormonal conditions, and skin-problems.

A new study confirms that nitrogen-containing substances that are used in the process of curing meats could affect the lungs.
