Trends in Osteoporosis Prevalence in Korea Using Korea National Health and Nutrition Examination Survey (KNHANES) 2024 and 2008-2011: The KSBMR KNHANES DXA Task Force Report.
Article in Journal of bone metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNational estimates of osteoporosis prevalence in Korea has been based on dual energy X-ray absorptiometry (DXA) data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2008 and 2011. In 2024, KNHANES resumed nationwide DXA testing, enabling updated prevalence estimates.
methodsWe compared the prevalence of osteoporosis (DXA T-score ≤-2.5 at lumbar spine, femoral neck, or total hip) and low bone mass (-1.0>T-score>-2.5 at any sites) among Korean adults aged ≥50 years between KNHANES 2008-2011 and 2024. Age-standardized prevalence estimates accounting for complex sampling were calculated. The Poisson regression model was used to assess prevalence ratios (PRs) between survey periods, with adjustment for anthropometric measures, lifestyle factors, and nutritional intake.
resultsThe prevalence of osteoporosis declined between KNHANES 2008-2011 and 2024 from 20.8% to 14.6% (women, 32.6%-22.0%; men, 7.0%-4.9%; P<0.001 for all), with higher mean BMD at all skeletal sites in 2024. In women, the prevalence of low bone mass increased from 47.9% to 56.0%, while it declined from 47.4% to 33.3% in men. The proportions of physician-diagnosed osteoporosis (24.9%-34.5%) and treatment (11.1%-22.8%) increased over time, particularly among women. In men, PR of osteoporosis between periods was attenuated after adjustment for height and weight, whereas changes in anthropometry, lifestyle, and nutrition did not fully account for the decline in women.
conclusionsFrom 2008 to 2011 and 2024, the prevalence of osteoporosis among Korean adults aged ≥50 years decreased, accompanied by improvements in the proportion of diagnosis and treatment.
