IntroductionThe discordance in the diagnosis of osteoporosis is characterized by the variation in bone mineral density measurements at different skeletal sites. The presence of discordance significantly alters the treatment plan as different treatment is required for different skeletal sites. The aim of this study was to find out the prevalence of hip-spine discordance in bone mineral densities in patients undergoing dual-energy x-ray absorptiometry scans for suspected osteoporosis.MethodsA descriptive cross-sectional study was conducted among patients undergoing dual-energy x-ray absorptiometry scans from 1 December 2020 to 30 October 2022. Ethical approval was taken from the Institutional Review Committee (Reference number: IRC-2020-11-18-08). Patients undergoing dual-energy x-ray absorptiometry scans for suspected osteoporosis were included. Patients aged less than 50 years, already diagnosed and under treatment for osteoporosis, and incomplete information about T-scores of hips and spine were excluded. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated.ResultsAmong 1028 patients, 602 (58.56%) (55.55-61.57, 95% Confidence Interval) had discordance in hip and spine bone mineral densities. The majority of them, 570 (94.68%) were female and 32 (5.71%) were male. Major discordance was observed in 101 (16.77%) patients and minor discordance was observed in 501 (83.22%) patients.ConclusionsThe prevalence of discordance in hip and spine bone mineral densities in patients undergoing dual-energy x-ray absorptiometry scans was higher than that reported in other similar studies done in similar settings.Keywordsbone density; osteoporosis; prevalence.
