| Abstract |
Few studies of bone loss have assessed the amount of loss directly after a hip fracture. The present prospective study was conducted to determine changes in bone mineral density (BMD) and muscle mass shortly after fracture and through 1 year to assess short-term loss and related factors. The setting was two acute care teaching hospitals in Baltimore, Maryland, and subjects were 205 community-dwelling women with a new fracture of the proximal femur between 1992 and 1995. Bone density of the nonfractured hip and whole-body and body composition were measured by dual-energy X-ray absorptiometry at 3 and 10 days and 2, 6 and 12 months after admission. Mean BMD of the femoral neck was 0.546 +/- 0.007 g/cm(2) at baseline. Average loss of femoral neck BMD from baseline was 2.1% at 2 months, 2.5% at 6 months and 4.6% at 12 months. The average loss of BMD in the intertrochanteric region was 2.1% at 12 months. Total lean body mass decreased by 6% while fat mass increased by 3. 6% by 1 year after the fracture. These findings indicate that significant loss in BMD and lean body mass occur shortly after hip fracture while body fat increases. Continued loss was evident throughout the 1 year of follow-up. This loss of both bone density and muscle mass may lead to new fractures. |

Attention Score in Context
This research output has an Altmetric Attention Score of 11. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 March 2017.
All research outputs
#2,709,651
of 22,856,968 outputs
Outputs from Osteoporosis International
#440
of 3,615 outputs
Outputs of similar age
#4,921
of 107,821 outputs
Outputs of similar age from Osteoporosis International
#2
of 7 outputs
Altmetric has tracked 22,856,968 research outputs across all sources so far. Compared to these this one has done well and is in the 87th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,615 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one has done well, scoring higher than 87% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 107,821 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 95% of its contemporaries.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
