Frailty is emerging as an important determinant for health. Compared with Western countries, research in the field of frailty started at a later stage in China and mainly focused on older community dwellers. Little is known about frailty in Chinese cancer patients, nor the risk factors of frailty. This study aimed at investigating the prevalence of frailty and its risk factors in elderly inpatients with gastric and colorectal cancer. This cross-sectional study was conducted at a tertiary hospital in China from Mar. 2020 to Nov. 2020. The study enrolled 265 eligible inpatients aged 60 and older with gastric and colorectal cancer who underwent surgery. Demographic and clinical characteristics, biochemical laboratory parameters, and anthropometric data were collected from all patients. The Groningen Frailty Indicator was applied to assess the frailty status of patients. A multivariate logistic regression model analysis was performed to identify the risk factors of frailty and to estimate their 95% confidence intervals. The prevalence of frailty in elderly inpatients with gastric and colorectal cancer was 43.8%. A multivariate logistic regression analysis showed that older age (OR = 1.065, 95% CI: 1.001–1.132, P = 0.045), low handgrip strength (OR = 4.346, 95% CI: 1.739–10.863, P = 0.002), no regular exercise habit (OR = 3.228, 95% CI: 1.230–8.469, P = 0.017), and low MNA-SF score (OR = 11.090, 95% CI: 5.119–24.024, P < 0.001) were risk factors of frailty. This study suggested a relatively high prevalence of frailty among elderly inpatients with gastric and colorectal cancer. Older age, low handgrip strength, no regular exercise habit, and low MNA-SF score were identified as risk factors of frailty.
