[Analysis on related risk factors of hip fracture patient with sarcopenia]

Abstract

Objective: To explore occurrence and risk factors of sarcopenia in patients with hip facture.

Methods: From May 2013 to January 2017, 187 patients with hip fractures were collected, including 99 males and 88 females aged from 50 to 95 years old with an average age of (77.40±10.58) years old. General conditions, appendicular skeletal muscle index (ASMI), total fat mass, bone mineral content (BMC), body mass index (BMI), grip strength, preoperative blood vitamin D (VITD), albumin, American Society of Anesthesiologists(ASA) classification and new mobility scores(NMS) were observed and analyzed. According to grip strength and ASMI, patients were divided into sarcopina group and non-sarcopina group, univariate and multivariate statistical methods were used to analyzed.

Results: Ninty-nine patients(52.9%) were diagnosed as sarcopenia. Compared with non-sarcopenia group, occurrence of sarcopenia was associated with advanced age, high ASA, low total fat mass, low bone mineral content, low BMI, low albumin, and low NMS. Subsequent binary logistic regression analysis showed that advanced age (OR=1.804, P=0.048), high ASA score (OR=3.052, P=0.001), low fat content (OR=0.843, P=0.006), low bone mineral salt(OR=0.203, P=0.026) were risk factors of hip fracture patient with sarcopenia.

Conclusions: Old age, high ASA score, low fat content, low bone mineral content may be related risk factors for sarcopenia in hip fracture patients.
