People suffering from asthma may be more prone to bone loss as re-searchers have now discovered links between asthma and a de-crease in bone mineral density. “We know prolonged use of corti-costeroids in the treatment of asth-ma is a risk factor of osteoporosis, but we have not had definite data showing the relationship between asthma itself and bone loss,” ex-plained Jae-Woo Jung of Seoul National University Medical Re-search Centre in South Korea. “This study has shown a meaning-ful association between the two conditions even in the absence of previous oral corticosteroid use,” Jung added. For the study, researchers exam-ined more than 7,000 patients, 433 of which had airway hyper-responsiveness (AHR) or asthma. Lumber spine and femur bone density was significantly lower in those with AHR or asthma, than those without the condi-tions, showed the findings of the research. “Reasons can include corticoster-oid use, low levels of vitamin D or even race,” said John Oppen-heimer, an associate editor of the journal Annals of Allergy, Asthma & Immunology that published the study.
