Risk Factors for Hip Fracture in Japanese Older Adults

Risk factors for hip fracture in Japanese older populations areunderstudied compared with Western countries arguably due to the relatively lowerprevalence rates in Japan. Nationally representative data from the Nihon UniversityJapanese Longitudinal Study of Aging were analyzed using logistic regression to examinepossible risk factors of hip fractures, separately for older women (n = 2,859) and oldermen (n = 2,108). Results showed that older Japanese women with difficulty bending theirknees (OR = 1.9), with diabetes (OR = 1.7 times), and/or with more activity of dailyliving limitations (OR = 1.1) had higher risks of hip fracture. Older Japanese men withdifficulty bending their knees (OR = 2.6), who use more external prescription drugs (OR= 1.9), and with cancer (OR = 2.0 times) had higher risks of hip fracture. Furtherconsiderations of gender- and culture-specific factors along with the identified riskfactors may provide insights into future intervention programs for hip fracture inJapanese older populations
