Some people may be able to break away from the addiction to nicotine cigarettes easily, but others may be experiencing difficulties and tend to be heavy smokers. The risk of addiction to nicotine vary in each person, is influenced by genetic factors.
According to a study published in the journal JAMA Psychiatry, someone who started smoking in their teens, tend to be heavy smokers, and the habit will continue throughout his life. Apparently, nicotine addiction is different in people with each other, depending on his genes.
Researchers from Duke University found that even if the gene is not likely to make a person more likely to try cigarettes, but genes may play a role on how people become addicted to nicotine. These findings highlight the importance of the child's life away smoking in their teens.
The study was conducted by observing the 1037 men and women who were part of the Dunedin Multidisciplinary Health and Development Study in New Zealand. Researchers have followed participants from birth until the age of 38 years to studying behavior, health, and lifestyle.
The research team created a 'genetic risk score' by observing marker genes thought to be associated with smoking. Based on the genetic risk score, researchers can predict who among the study participants were more likely to be addicted to nicotine.
Of the total study participants, as many as 880 people have been trying to smoke. Genetic risk scores can not predict who will try smoking, but researchers found that individuals with a high genetic risk scores, 24 percent more likely to be daily smokers at age 15 and 43 percent more likely to be daily smokers at age 18.
While in adults with a high genetic risk scores, 27 percent more likely to maintain the habit of smoking and 22 percent more likely to have failed in his attempt to stop smoking.
"However, the results showed that individuals with a high genetic risk for smoking habits, can continue to develop addiction to cigarettes even though he started smoking as an adult," said Daniel Belsky, the lead researcher in a written statement Everyday Health, Thursday (28/3 / 2013).
However, people with a high genetic risk and have started smoking as a teenager, would be more likely to become heavy smokers later in life. This is because the genetic risk will be more powerful in the age group.
Thus, it is important for parents to keep cigarettes from children who started a teenager. You may not be able to watch any time during the 24 hours, but you need to do is to provide care and guidance to children.
Children who lack attention from their parents, tend to look for his own pleasure and more likely to try to smoke. However, the genetic risk for cigarettes will not cause addiction if you never start smoking.
