Association between Hyperkyphosis and fall incidence among c
Hyperkyphosis is frequently found in adults aged 65 years and older and may be associated with falls. Researchers aimed to investigate prospectively in community-dwelling older adults whether hyperkyphosis or change in the kyphosis angle is associated with fall incidence.

Community-dwelling older adults (n=1220) reported falls weekly over 2 years. Thoracic kyphosis was measured through the Cobb angle between the fourth and 12th thoracic vertebra on DXA-based vertebral fracture assessments and defined hyperkyphosis as a Cobb angle more than 50°. The change in the Cobb angle during follow-up was dichotomized.

--Hyperkyphosis was present in 15% of the participants. During follow-up, 48% of the participants fell at least once.

--In the total study population, hyperkyphosis was not associated with the number of falls (adjusted IRR 1.12).

--Researchers observed effect modification by age. In the oldest quartile, aged 77 years and older, hyperkyphosis was prospectively associated with a higher number of falls. Change in the kyphosis angle was not associated with fall incidence.

Conclusively, Hyperkyphosis was associated with a higher fall incidence in the oldest quartile of a large prospective cohort of community-dwelling older adults.
