Smoking has been widely considered a risk factor for future bone fracture, but researchers have now identified certain lung-related factors – such as smoking or passive smoke – can help in predicting an individual smoker’s fracture risks.
“Hip fractures are associated with significant morbidity and mortality in smokers with lung disease, but whether lungaspecific factors are associated with fracture risk is unknown,” said authors who conducted the study. The authors are from the University of Pittsburgh in the US
Scientists said that the goal of the researcher was to find out whether lungaspecific factors are associated with incidents of hip fracture. They also tried to determine if they improve risk discrimination of traditional fracture risk models in smokers.
The study has been published in the Journal of Bone and Mineral Research. 9,187 adults who currently or formerly smoked, were involved in the study. There were 361 new hip fractures reported over a median follow-up of 7.4 years.
Some of known risk factors associated with experiencing a hip fracture included osteoporosis, older age, female sex, previous spine and hip fracture, rheumatoid arthritis and diabetes.
The study suggested that the incorporation of lungaspecific risk factors into fracture risk assessment tools may more accurately predict fracture risk in smokers.
“We need to look beyond traditional risk factors when making osteoporosis screening and management decisions in our patients with chronic obstructive pulmonary disease (COPD),” said study lead author Jessica Bon from the University of Pittsburgh.
“A former smoker with frequent COPD exacerbations or significant emphysema on chest CT scan may be at greater risk of fracture than would be expected based on age or sex or other underlying comorbidities alone,” Bon noted.
Earlier, a study found that the tobacco smoking could be a potential risk factor for infection with the novel coronavirus. The study suggests that there is an increased risk for the virus binding and gaining entry into the lungs of smokers than non-smokers.
