Factors that cause women with osteoporosis to fall

Objective

To analyze and compare intrinsic and extrinsic factors that cause falls among women receiving treatment for osteoporosis.

Subjects and methods

A cross-sectional study of women ≥50 years receiving treatment for osteoporosis. Participants filled out questionnaires (demographic characteristics), and researchers took anthropometric measurements of bone mineral density, handgrip strength (HGS), ankle range of motion (ROM), and gait speed (GS). We also evaluated the Timed Up and Go Test (TUGT), Five Times Sit-to-Stand Test (SST), and Falls Efficacy Scale-International (FES-I) and investigated the extrinsic factors for falls.

Results

We included 144 participants (71.6 [8.3 years]), who reported 133 falls. We classified participants into a non-faller group (NFG; 0 falls, n=71, 49.5%), a faller group (FG; 1 fall, n=42, 28.9%), and a recurrent-faller group (RFG; more than 1 fall, n=31, 21.5%). Most patients had an increased risk of falling according to the TUGT, SST, reduced ankle ROM, and GS (P<.005 for all). FES-I was associated with sporadic and recurrent falls. For the multivariate analysis, the number of falls was influenced by the presence of ramps (RR 0.48, 95% CI, 0.26-0.87, P=.015), uneven surfaces (RR 1.6, 95% CI. 1.05-2.43, P=.028), and antislippery adhesive on stairs (RR 2.75, 95% CI, 1.77-4.28, P<.001).

Conclusion

Patients receiving treatment for osteoporosis are influenced by intrinsic and extrinsic factors that cause falls. Lower-limb strength and power-discriminated participants at a higher risk of falls, but extrinsic factors varied. Only uneven floors and antislippery adhesives on stairs were associated with increased frequency of falls.

Incidence of hip fractures during the COVID-19 pandemic in the Brazilian public health care system

This study compared the incidence of hip fractures before and during the COVID-19 pandemic in Brazil, aged ≥ 60 years excluding all fractures related to any trauma. There was a significant reduction in the number of hip fractures and the length of hospital stay during the period of social isolation.

PURPOSE

To compare the incidence of hip fractures before and during the COVID-19 pandemic in Brazil and in the main regions of the country in patients covered by the Brazilian public health care system (SUS). As far as we are aware, no studies have evaluated the impact of COVID-19 pandemic on hip fractures in Brazil.

METHODS

Descriptive, cross-sectional study in individuals aged ≥ 60 years who presented with a hip fracture before and during the COVID-19 pandemic and received treatment covered by the SUS. The data were collected from the DATASUS electronic database. We calculated the incidence, mortality, lethality, duration of hospitalization, and average reimbursement associated with the treatment of the fractures.

RESULTS

There was a significant reduction in the incidence of hip fractures among individuals aged ≥ 60 years in Brazil during the period of social isolation due to COVID-19. The observed incidence was 15.58/10,000 inhabitants between March and December 2020 and 16.07/10,000 inhabitants in the same period of 2019 (p < 0.005; main decline observed in the age groups > 70 years). The average length of hospital stay reduced from 8.35 days in 2019 to 7.33 days in 2020, following a similar pattern of reduction across all regions. The Southeast was the only region with a significant reduction in mortality during the pandemic (relative risk 0.90, 95% confidence interval 0.84-0.97, p < 0.005).

CONCLUSION

During the COVID-19 pandemic in Brazil, the incidence rate of hip fractures and the associated duration of hospital stay decreased among patients aged ≥ 60 years.
