  •   Objective  To explore the association of serum homocysteine (Hcy) levels with sarcopenia and cognitive function in elderly inpatients.   Methods  A total of 346 elderly patients hospitalized in The Affiliated Geriatric Hospital of Nanjing Medical University from June 2017 to March 2020 were selected, including 122 cases (35.3%) with sarcopenia and 224 cases (64.7%) without sarcopenia. Walking speed, grip strength and limb skeletal muscle index (ASMI) were used to diagnose sarcopenia, and MMSE was used to assess cognitive function. The differences in Hcy level and cognitive function between the sarcopenia group and the non-sarcopenia group were compared, the relationship between Hcy level and the severity and cognitive function of sarcopenia was analyzed, and the influencing factors related to sarcopenia were analyzed by multiple factors.   Results  (1) Compared with the non-sarcopenia group, the sarcopenia group was older and had lower body mass index (BMI), serum albumin level, MMSE score and education level (all P < 0.001) and higher Hcy level (P=0.011). (2) Pearson correlation analysis showed that high Hcy level was negatively correlated with low gait speed, low ASMI and low MMSE score (all P < 0.05). (3) Multivariate logistic regression analysis revealed that age, high BMI and high education level were related to sarcopenia in total subjects. High education level and high BMI in males and age, high Hcy level, high BMI and high education level in females were associated with the presence of sarcopenia.   Conclusions  The higher Hcy level in elderly patients with sarcopenia, the more severe the decline of ASMI, gait speed and cognitive function. High Hcy level is a risk factor for sarcopenia in elderly women. High education level and high BMI are protective factors for sarcopenia. Serum Hcy level may be used as a monitoring index for sarcopenia, which has a certain clinical significance in disease evaluation and prognosis prediction.
