  • Condom Use

Understanding why teens use or don't use condoms could be crucial in steering them away from risky behaviors. A survey of more than 1,300 sexually active adolescents found teens were more likely to use condoms with casual partners, than partners they considered "serious." Researchers from Brown Medical School say this illustrates that teens might overestimate the safety of using condoms with casual partners and underestimate the risk of unprotected sex with a more steady partner. The number of unprotected sex acts within 90 days prior to the study was virtually the same between the groups that had serious and casual partners. Boys were significantly more likely to report having "casual" partners than girls. Study led by researchers at the Bradley Hasbro Children's Research Center and Brown Medical School and published the Journal of Adolescent Health, in September 2006.

  • Nicotine Withdrawal

New research shows nicotine withdrawal symptoms can start just a half an hour after smoking a cigarette. During a recent study, researchers observed 50 pack-a-day smokers for four hours half could smoke at will, the other half were asked not to smoke during the study. They found the participants who were asked not to smoke started craving cigarettes 30 minutes after the study started. They were angry by the end of the first hour, and performed poorly on tests that required sustained attention. The researchers found the participants who could smoke during the study had a cigarette every 40 minutes.  A study led by researchers at the University of South Florida and published in the Journal Psychopharmacology.

  • Overweight Effect

Being just a few pounds overweight may significantly shorten your life. A study of over 500,000 Americans found being overweight increased the chance of premature death by 20% to 40%. Participants who were obese had a double, sometimes triple, increased risk for early death. Researchers used participants' B-M-I scores, a calculation of body fat, to determine if they were overweight which was considered 1 to 29 pounds above normal. There were limitations with the study: the participants were asked to recall their weight, no measurements were made, and the population surveyed may not be representative of all Americans.
