Analysis of the association between smoking and fractures after acute ischemic stroke
Smokers, fracture risk 1.2 times higher… hip fracture risk 1.8 times higher
Because brain cells damaged by a stroke are difficult to recover, stroke victims have a decreased sense of energy and balance, which increases the risk of fractures. In particular, smoking after suffering an acute ischemic stroke has been shown to significantly increase the risk of fractures.
A research team including Professor Dae-Young Cheon and Professor Jin-Hwa Lee of the Department of Cardiology at Hallym University Dongtan Sacred Heart Hospital, Professor Min-Woo Lee of the Department of Neurology at Hallym University Sacred Heart Hospital, and Professor Kyung-Do Han of the Department of Information, Statistics and Actuarial Science at Soongsil University announced on the 8th the results of analyzing 177,787 people aged 40 or older diagnosed with acute ischemic stroke from January 2010 to December 2016 using medical data from the National Health Insurance Corporation.
Ischemic stroke is a disease in which brain tissue is damaged and cannot function properly due to narrowing or blockage of cerebral blood vessels. The number of stroke patients in Korea is continuously increasing. According to statistics from the Health Insurance Review & Assessment Service, the number of stroke patients last year was 657,277, a 6% increase over the past five years.
Among the research team’s subjects, 115,380 were non-smokers, 24,798 were former smokers, 12,240 were those who quit smoking after a stroke, 3,710 were new smokers after a stroke, and 21,659 were continuous smokers before and after a stroke.
Of the total subjects, 14,991 (8.4%) suffered fractures, of which 2,054 (1.2%) suffered hip fractures and 7,543 (4.2%) suffered spinal fractures. After adjusting for variables such as age, physical activity, and underlying diseases, the analysis of fracture risk showed that smoking significantly increased the risk of fracture after stroke. Compared to non-smokers, new and continuous smokers had a 1.2 times higher risk of fracture. However, in those who quit smoking after stroke, the risk of fracture was no different from that of non-smokers.
In addition, the risk of hip fracture was 1.5 times higher in continuous smokers and 1.8 times higher in new smokers compared to non-smokers, indicating that the risk of hip fracture was higher in new smokers than in continuous smokers. The risk of spinal fracture was 1.3 times higher in continuous smokers than in non-smokers.
Professor Chun Dae-young said, “This study confirmed that if you continue to smoke or start smoking again after a stroke, the risk of fracture increases significantly.” He added, “In particular, the increased risk of hip and spinal fractures suggests that smoking has a detrimental effect on maintaining bone strength and integrity in skeletal areas that bear a lot of weight and are subject to greater mechanical stress.”
Professor Lee Jin-hwa said, “The results of this study showed that smoking cessation education after stroke can significantly reduce the risk of fractures and potentially improve the quality of life of stroke survivors.”
The results of this study were published in the June issue of the Journal of the American Heart Association, an international academic journal of the SCIE level.
