Abstract Disclosure: A. Atri: None. C. Anastasopoulou: None. Introduction: Fragility hip fractures are a major public health burden and are considered a good measure of the quality of healthcare. However, contemporary trends in fragility hip fractures in women with low femoral neck bone mineral density (BMD) in the United States are not known. Methods: We used data from the National Health and Nutrition Examination Survey (NHANES) for the years 2009-10, 2013–14 and 2017–18 to include U.S. women aged ≥ 60 years with bone mineral density (BMD) T score ≤ -1 at the femur neck, which was measured by dual energy x-ray absorptiometry (DEXA) on Hologic Discovery Model A Densitometers (Hologic, Inc., Bedford, Massachusetts). Fragility fracture at the hip was defined as self-reported hip fracture resulting from a fall from standing height or less. Participants with missing BMD and fracture data were excluded. ANOVA was used for comparing means. The Cochran-Armitage test was utilized for trend analysis. Results: Overall, in women aged ≥ 60 years with femoral neck T score ≤ -1, the average age of women of low BMD decreased from 71(±7.2) years to 69.6 (±6.7) years, whereas the mean T-score modestly worsened from – 1.96 (±0.62) to -2.04 (±0.77) from 2009-10 to 2017-18. Similarly, the prevalence of women with T score ≤ -2.5 increased from 18.1% to 21.3%. We also found no significant change in proportion of women who reported treatment for osteoporosis (2009-10: 19.8%, 2013-14: 18.5%, 2017-18: 19.7%; p trend = 0.052). However, proportion of women who experienced fragility hip fractures decreased significantly (2009-10: 2.4%, 2013-14: 1.5%, 2017-18: 1.2%; p trend = 0.001). The mean age of index fragility hip fracture was 70.6 years in 2009-10, 68.3 years in 2013-14 and 71.7 years in 2017-18 (p = 0.001). Age stratified analysis showed a decreasing trend in proportion of women ≥ 80 years who experienced their index fragility hip fracture (2009-10: 25.9%, 2013-14: 14.7%, 2017-18: 15%; p trend = 0.001) and 70-79 years (2009-10: 40.9%, 2013-14: 21.1%, 2017-18: 35.8%; p trend = 0.001), while an increasing trend was seen in women 60–69 years (2009-10: 33.2%, 2013-14: 64.2%, 2017-18: 49.2%; p trend = 0.001). Discussion In this nationally representative cohort of community-dwelling US women with a low femoral neck BMD, we found a 50% decrease in burden of fragility hip fractures over a 10-year period from 2009-10 to 2017-18. This trend was observed despite worsening mean femoral neck T-scores, T score ≤ -2.5, and similar rates of osteoporosis treatment. Interestingly, the proportion of women who experienced their index fragility hip fracture showed a declining trend among the 70-79 years and ≥ 80 years age-groups. This change may be due to increasing awareness and utilization of measures to decrease falls such as exercise, nutrition, health education and environment modifications targeted towards the elderly population.
