Objective To evaluate the value of multiple obesity indicators in predicting hypertension of the elderly population aged 65 years and above,to provide a scientific basis for the timely identification of hypertensive patients and high-risk groups,and to provide a strategic reference for the early intervention of hypertension in the elderly.Methods A total of 6873 elderly people who received health checkups at a community health service centre in Wuhan from March 2022 to December 2023 were selected as the study subjects.The Chinese visceral adipose index(CVAI),a body shape index(ABSI),conicity index(CI)and cardiometabolic index(CMI)were calcu-lated,the area under the curve(AUC)of the receiver operating characteristic(ROC)curve was used to analyze and compare the ability of the above obesity indicators for identifying the risk of hypertension in elderly people of different genders.Results There were signifi-cant differences in all obesity indexes between different gender(P＜0.05).The differences in AUC for identifying the risk of hypertension among ABSI,CI and CMI in males,and CVAI,ABSI and CI in females were statistically significant(P＜0.05),and the AUC were 0.524,0.575,0.611,0.635,0.530,0.565,respectively.The AUC of CMI in males and CVAI in females for identifying the risk of hypertension was larger than other indicators.Conclusion Obesity indicators for identifying the risk of hypertension differ between gen-ders;CMI and CVAI are the best indicators for predicting the risk of hypertension in elderly males and females,respectively;the commu-nity can apply and promote the corresponding obesity indicators for elderly hypertensive patients of different genders to improve the early intervention and prevention of hypertension.

Objective:To analyze the clinical symptoms and epidemiological characteristics of patients with tsutsugamushi disease (TD) in Utica County, Shiyan City, providing reference for scientific prevention and control of TD.Methods:The information of 57 TD patients admitted to the Department of Infectious Diseases of the People's Hospital of Utica County in Shiyan City from January to December 2022 was collected, including age, gender, occupation, clinical manifestations (tarsus or chigger, high fever, rash and accompanying syndromes), laboratory and imaging test results, and field work and travel history. Blood samples and body crusts were collected, and enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) were used to detect antibodies against Orientia tsugamushi (Ot-Ab-IgM) and Orientia tsutsugamushi (Ot). The scores of each patient were calculated using the TD Diagnostic Scale. A score of ≥8.5 was considered a clinical diagnosis of TD. According to the number of system functional damages (0, 1, 2, ≥3), 57 patients were divided into 4 groups, A, B, C, and D, TD was analyzed for system functional damages of each system.Results:Among the 57 TD patients, 26 (45.61%) were male and 31 (54.39%) were female, and the proportion of patients aged 40 - 79 years was 92.98% (53/57); farmers accounted for 89.47% (51/57). May was the peak of TD incidence, with 19 cases, which accounted for 33.33% (19/57) of the total number of patients affected that year. Fifty-four patients had a history of fieldwork or field trips before the onset of the disease. The incidence of high fever in 57 TD patients was 100.00%(57/57), the detection rate of body scorch or chiggers was 80.70% (46/57), and the incidence rate of rash was 98.25% (56/57); the incidence rate of tsutsugamushi disease triad (accompanied by scabs, high fever, and rash) was 80.70% (46/57); the incidence of eosinophil decline was 100.00%(57/57), and 77.19% (44/57) of TD patients experienced multiple-system functional damage (MSFD). The TD score diagnostic scale for 57 patients ranged from 8.5 to 10.5 points. After being hospitalized for 1 - 5 days, all TD patients experienced a decrease in body temperature to the normal range, and the damage to various systems functional gradually recovered.Conclusions:TD has become one of the most common natural infectious diseases in Utopia County, Shiyan City, Hubei Province. The patients are mainly middle-aged and elderly people, and the triple syndrome is a typical clinical manifestation. Asymptomatic injuries to the blood system, liver and kidneys are the most common.
