Why do young adults start smoking?

Researchers are increasingly concerned about this issue

2013-09-17
(Press-News.org) The risk of becoming a smoker among young adults who have never smoked is high: 14% will become smokers between the ages of 18 and 24, and three factors predict this behaviour. "Smoking initiation also occurs among young adults, and in particular among those who are impulsive, have poor grades, or who use alcohol regularly," said Jennifer O'Loughlin, a Professor at the University of Montreal School of Public Health (ESPUM) and author of a Journal of Adolescent Health study published in August. O'Loughlin believes smoking prevention campaigns should also target young adults aged 18 to 24. A recent phenomenon With smoking rates declining markedly in the past three decades, the researchers cited several studies suggesting that the tobacco industry is increasing its efforts to appeal to young adults. In the United States, there is a 50% increase in the number of young adults who start smoking after high school. This trend prompted O'Loughlin and her team at the ESPUM to identify predictors of young adults starting to smoke which may lead to avenues for prevention. They analyzed data from a cohort study called "NDIT" (Nicotine Dependence in Teens), which began in 1999 in the Greater Montreal Area, in which nearly 1,300 young people aged 12-13 took part. In this cohort, fully 75% tried smoking. Of these young people, 44% began smoking before high school; 43% began smoking during high school, and 14% began after high school. Not all, however, continued smoking, but among the "late" smokers, the researchers found that smoking onset is associated with three risk factors: high levels of impulsivity, poor school performance, and higher alcohol consumption. Explaining the three risk factors Some late smokers showed greater impulsivity compared to the other participants in the study. According to O'Loughlin, it is possible that impulsivity is more freely expressed when one becomes an adult, since parents are no longer there to exert control. "We can postulate that parents of impulsive children exercise tighter control when they are living with them at home to protect their children from adopting behaviours that can lead to smoking, and this protection may diminish over time," she explains. In addition, school difficulties increase the risk of becoming a smoker because they are related to dropping out of school and, seeking employment in workplaces where smoking rates are higher. Finally, since young people are more likely to frequent places where they can consume alcohol, they are more prone to be influenced by smokers, or at least be more easily tempted. "Since alcohol reduces inhibitions and self-control, it is an important risk factor for beginning to smoke," warns O'Loughlin. Toward targeted prevention campaigns Smoking prevention campaigns usually target teenagers because studies show that people usually begin to smoke at age of 12 or 13. The phenomenon is well known, and numerous prevention programs are geared toward teenagers. "Our study indicates that it is also important to address prevention among young adults, especially because advertizing campaigns of tobacco companies specifically target this group," says O'Loughlin. "This is particularly important because if we can prevent smoking onset among young adults, the likelihood that they will never become smokers is high," she says.

Self-referral spurs unnecessary MRI exams for patients

2013-09-17
OAK BROOK, Ill. – Patients having knee MRI examinations are significantly more likely to receive a negative finding if referred by physicians who have a financial interest in the imaging equipment being used, according to a study published online in the journal Radiology. Imaging self-referral, whereby a non-radiologist physician refers their own patients for imaging to facilities in which they or their partners have a financial interest, is a growing trend in medicine and a significant driver of healthcare costs. Medical imaging self-referral leads to higher utilization ...

New marker identified for early diagnosis of lung cancer

2013-09-17
PHILADELPHIA — A protein called isocitrate dehydrogenase (IDH1) is present at high levels in lung cancers and can be detected in the blood, making it a noninvasive diagnostic marker for lung cancers, according to a study published in Clinical Cancer Research, a journal of the American Association for Cancer Research. "This study is the first to report identification of IDH1 as a novel biomarker for the diagnosis of non-small cell lung cancers (NSCLC) using a large number of clinical samples," said Jie He, M.D., Ph.D., director of the Laboratory of Thoracic Surgery at ...

Study reveals link between oil spill exposure and hematologic and hepatic toxicity

2013-09-17
Philadelphia, PA, September 17, 2013 – A new study reports that workers exposed to crude oil and dispersants used during the Gulf oil spill cleanup display significantly altered blood profiles, liver enzymes, and somatic symptoms compared to an unexposed control group. Investigators found that platelet counts were significantly decreased in the exposed group, while both hemoglobin and hematocrit levels were notably increased. Their findings, reported in The American Journal of Medicine, suggest that oil spill cleanup workers are at risk for developing hepatic or blood-related ...

Financial incentives motivate sedentary adults to exercise

TORONTO, September 17, 2013 – A review study published today finds that financial incentives –as modest as $5 per week – can increase the amount of exercise people do. Lead author Marc Mitchell, University of Toronto PhD candidate and Cardiac Rehabilitation Supervisor at Toronto Rehab, worked under the leadership of University of Toronto exercise psychologist Guy Faulkner and exercise physiologist Jack Goodman to publish these findings in the September online publication of the American Journal of Preventive Medicine. The review study looked at 1,500 patients. "The ...

Marine species distribution shifts reflect local climate conditions

2013-09-16
Climate change has resulted in shifts in where and at what depths many marine species are found. These shifts have not been uniform, and sometimes have occurred at different rates and in different ways than expected. The leading explanation for these changes has been biological differences among species, but a new study suggests that the local climatic conditions are more likely causing these shifts In a study published September 13 in the journal Science, researchers from the U.S. and Canada suggest that climate velocity – the rate and direction that climate shifts in ...

Can olive leaf extract attenuate lead-induced brain injury?

2013-09-16
In recent years, neurotoxicity from exposure to low levels of lead in the environment has become increasingly prevalent. Therefore, the discovery of herbs that have lead-eliminating properties without harmful side effects is essential for the management of lead poisoning. Preliminary studies by Yu Wang and colleagues from Longnan Teachers College have verified that olive leaf extract can protect the blood, spleen and hippocampus in lead-poisoned mice. However, little is known about the effects of olive leaf extract on lead-induced brain injury. A recent study from Yu Wang ...

Does rutaecarpine relieve cerebral ischemia reperfusion injury?

2013-09-16
Rutaecarpine, an active component of the traditional Chinese medicine Tetradium ruticarpum, has been shown to improve myocardial ischemia reperfusion injury, mainly focusing on calcitonin gene-based targets. Because both cardiovascular and cerebrovascular diseases are forms of ischemic vascular disease, they are closely related. A recent study reported by Chunlin Yan and colleagues from Hebei North University for the first time investigated the neuroprotective effects and mechanism of action of rutaecarpine on nerve function and learning and memory following cerebral ischemia ...

However, the therapeutic ef-fects of this technique in patients with symptomatic internal carotid artery occlusion remain controversial. Prof. Feng Ling and team from Capital Medical University retrospectively collected 65 patients with extracranial internal carotid artery occlusion who underwent carotid endarterectomy, carotid endarterectomy combined with Fogarty catheter embolectomy, or hybrid surgery in the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, ...

White blood cell levels tied to meal time

2013-09-16
A new link between meal times and daily changes in the immune system has been identified by UC San Francisco researchers, and has led them to question assumptions about the roles of specific immune cells in infection and allergy. A white blood cell of the immune system that is thought to fight parasitic worms might actually help the invaders, according to Richard Locksley, MD, professor of medicine at UCSF and the senior author of the new study, published online today (September 15, 2013) in Nature. Locksley's lab team found in mice that a type of rare immune cell serves ...
