NHLBI study shows smoking cessation programs improve survival

15.02.2005


New findings from the Lung Health Study (LHS) show that intensive smoking cessation programs can significantly improve long-term survival among smokers. Supported by the National Heart, Lung, and Blood Institute (NHLBI), LHS is a landmark study that differs from many other studies of cigarette smoking in that it was a randomized, controlled clinical trial -- considered the gold standard in determining cause and effect; furthermore, the size and duration of LHS enabled it to more accurately measure the risks associated with smoking than other clinical trials. NHLBI is part of the National Institutes of Health.



LHS followed nearly 5,900 middle-aged smokers who had mild to moderately abnormal lung function but were otherwise healthy when they enrolled in the study. Participants were assigned to either a 10-week intensive smoking cessation program or to usual care (no intervention). The intervention program included behavior modification and use of nicotine gum, with a continuing five-year maintenance program to minimize relapse. After five years, approximately 22 percent of the participants in the smoking cessation program were sustained quitters, with nearly 90 percent of them continuing their success after 11 years. About 5 percent of those who did not receive the intervention were sustained quitters after five years. After an average of 14.5 years, the death rate among those in the smoking cessation program was about 15 percent lower compared to those who received usual care. The results are published in the February 15, 2005, issue of the Annals of Internal Medicine.

"This study shows the substantial impact smoking cessation programs can have on public health, even if small numbers of participants successfully quit," said Gail Weinmann, MD, director of the NHLBI Airway Biology and Disease Program.


Researchers also analyzed mortality data according to smoking habit regardless of whether participants were in the intervention or usual care groups. At the end of the study they found that sustained quitters had nearly half the overall death rate of those who continued to smoke. In particular, death rates of sustained quitters compared to smokers were nearly one-third lower for coronary heart disease and for cardiovascular disease, and less than half for lung cancer.

In an accompanying editorial, Jonathan Samet, MD, MS, of the Johns Hopkins Bloomberg School of Public Health, notes that the LHS findings prove that "smoking is causally responsible for the increased risk for death in smokers." He asserts, "No one can make a serious claim to the contrary in light of this randomized trial evidence."

Smoking is the single most avoidable cause of disease, disability, and death in the United States. According to the Centers for Disease Control and Prevention, approximately 22.5 percent of adults (46 million) and 26 percent of high school seniors smoke. Smoking contributes to more than 440,000 deaths per year.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
