Study: Smokers better off quitting, even with weight gain

  • Quitters saw their risk of diabetes increase by 22 percent in the six years after they kicked the habit
  • The people enrolled in the studies were all health professionals, and did not mirror current smokers in the general population, who are disproportionately low-income, less-educated and more likely to smoke heavily

NEW YORK: If you quit smoking and gain weight, it may seem like you’re trading one set of health problems for another. But a new US study finds you’re still better off in the long run.
Compared with smokers, even the quitters who gained the most weight had at least a 50 percent lower risk of dying prematurely from heart disease and other causes, the Harvard-led study found.
The study is impressive in its size and scope and should put to rest any myth that there are prohibitive weight-related health consequences to quitting cigarettes, said Dr. William Dietz, a public health expert at George Washington University.
“The paper makes pretty clear that your health improves, even if you gain weight,” said Dietz, who was not involved in the research. “I don’t think we knew that with the assurance that this paper provides.”
The New England Journal of Medicine published the study Wednesday. The journal also published a Swedish study that found quitting smoking seems to be the best thing diabetics can do to cut their risk of dying prematurely.
The nicotine in cigarettes can suppress appetite and boost metabolism. Many smokers who quit and don’t step up their exercise find they eat more and gain weight — typically less than 10 pounds (4.5 kilograms), but in some cases three times that much.
A lot of weight gain is a cause of the most common form of diabetes, a disease in which blood sugar levels are higher than normal. Diabetes can lead to problems including blindness, nerve damage, heart and kidney disease and poor blood flow to the legs and feet.
In the US study, researchers tracked more than 170,000 men and women over roughly 20 years, looking at what they said in health questionnaires given every two years.
The people enrolled in the studies were all health professionals, and did not mirror current smokers in the general population, who are disproportionately low-income, less-educated and more likely to smoke heavily.
The researchers checked which study participants quit smoking and followed whether they gained weight and developed diabetes, heart disease or other conditions.
Quitters saw their risk of diabetes increase by 22 percent in the six years after they kicked the habit. An editorial in the journal characterized it as “a mild elevation” in the diabetes risk.
Studies previously showed that people who quit have an elevated risk of developing diabetes, said Dr. Qi Sun, one the study’s authors. He is a researcher at the Harvard-affiliated Brigham and Women’s Hospital.
But that risk doesn’t endure, and it never leads to a higher premature death rate than what smokers face, he said.
“Regardless of the amount of weight gain, quitters always have a lower risk of dying” prematurely, Sun said.


NASA finds Indian moon lander with help of amateur space enthusiast

NASA finds Indian moon lander with help of amateur space enthusiast

  • NASA released an image taken by its Lunar Reconnaissance Orbiter that showed the site of the spacecraft’s impact
  • A version of the picture was marked up to show the associated debris field

WASHINGTON: India’s Vikram lunar lander, which crashed on its final approach to the Moon’s surface in September, has been found thanks in part to the sleuthing efforts of an amateur space enthusiast.
NASA made the announcement on Monday, releasing an image taken by its Lunar Reconnaissance Orbiter (LRO) that showed the site of the spacecraft’s impact (September 7 in India and September 6 in the US).
A version of the picture was marked up to show the associated debris field, with parts scattered over almost two dozen locations spanning several kilometers.
In a statement, NASA said it released a mosaic image of the site on September 26 (but taken on September 17), inviting the public to compare it with images of the same area before the crash to find signs of the lander.
The first person to come up with a positive identification was Shanmuga “Shan” Subramanian, a 33-year-old IT professional from Chennai, who said that NASA’s inability to find the lander on its own had sparked his interest.
“I had side-by-side comparison of those two images on two of my laptops ... on one side there was the old image, and another side there was the new image released by NASA,” he said, adding he was helped by fellow Twitter and Reddit users.
“It was quite hard, but (I) spent some effort,” said the self-professed space nerd, finally announcing his discovery on Twitter on October 3.
NASA then performed additional searches in the area and officially announced the finding almost two months later.
“NASA has to be 100% sure before they can go public, and that’s the reason they waited to confirm it, and even I would have done the same,” said Subramanian.
Blasting off in July, emerging Asian giant India had hoped with its Chandrayaan-2 (“Moon Vehicle 2“) mission to become just the fourth country after the United States, Russia and regional rival China to make a successful Moon landing, and the first on the lunar south pole.
The main spacecraft, which remains in orbit around the Moon, dropped the unmanned lander Vikram for a descent that would take five days, but the probe went silent just 2.1 kilometers above the surface.
Days after the failed landing, the Indian Space Research Organization said it had located the lander, but hadn’t been able to establish communication.
