Abstract: Objective To explore the prevalence and influencing factors of sarcopenia(SA)in the elderly patients with H-type hypertension, and to provide reference for prevention and early intervention. Methods A total of 191 elderly patients(aged ≥60 years old) with H-type hypertension who received medical examinations from March to June 2021 were enrolled. According to the diagnostic criteria of SA of Asian Working Group for Sarcopenia 2019(AWGS), the patients were divided into the SA group(n=93) and the non-SA group(n=98). General information and laboratory test results were collected and compared between the two groups. Binary Logistic regression analysis was used to analyze the influencing factors for SA in the elderly patients with H-type hypertension. Results The waist circumference, neck circumference, calf circumference and BMI were significantly lower and the levels of age, diastolic blood pressure, platelet count and high-density lipoprotein cholesterol(HDL-C)were higher in the SA group than those in the non-SA group(P<0.01). The SA detection rates were 100%, 72.2%, 23.4% and 6.7% in the emaciated, normal-sized, overweight and obese individuals, respectively. The SA detection rate decreased with the increase of BMI (χ² _trend= 59.78, P < 0.001). Logistic regression analysis showed that BMI(OR=0.682,95%CI:0.555-0.838)and calf circumference(OR=0.621,95%CI:0.480-0.805)were the protective factors for the development of SA(P<0.05), and platelet counts(OR=1.012,95%CI:1.004-1.019)and HDL-C levels(OR=3.026,95%CI:1.105-8.283) were the risk factors for SA in the elderly patients with H-type hypertension(P<0.05). Conclusions The prevalence of SA in the elderly patients with H-type hypertension is high. Platelet count, HDL-C, BMI and calf circumference are the influencing factors for SA in the elderly patients with H-type hypertension.
