| Objective: To investigate the frailty status of elderly type 2 diabetes patients in China,understand the characteristics of gait parameters of diabetes patients with different frailty status under natural normal speed and dual tasks,and explore the relationship between frailty status of elderly type 2 diabetes patients and walking gait characteristics under different tasks.Methods: Patients in the department of endocrinology of two third-level class a hospitals in Hefei were selected as subjects by convenient sampling.The survey period was from June 2018 to September 2019,and 251 cases were collected.Demographic data were collected by questionnaire.The MMSE was adopted for cognitive state.Fried phenotype scale was used to evaluate the degree of frailty of patients.According to the scale score,subjects were divided into non-frailty,pre-frailty and frailty.The IDEEA was used to quantitatively collect gait parameters of three groups of patients in two walking states.Epi Data3.1 software was used for data entry by two people,and SPSS25.0 software was used for data statistical analysis.To explore the factors affecting frailty in elderly patients with type 2 diabetes and whether there are differences between natural normal speed and dual task under different frailty conditions.Results:(1)Among 251 patients with diabetes included in this study,there was 54(21.51 %)of frailty,104(41.44 %)of pre-frailty and 93(37.05 %)of no-frailty.(2)Multiple Logistic Regression Analysis showed that gender(OR=2.999)was the influencing factors in the pre-frailty.Lack of fear of falling(OR=0.324),women(OR=2.545),number of illnesses(OR=1.385),and Hb A1 C level(OR=0.327)were influential factors in frailty.(3)Natural normal walking test: The difference in step speed,step frequency and step length between the non-frailty group and pre-frailty group were statistically significant(P<0.05).The differences in step frequency,step length,step speed and stride time between the non-frailty group and frailty group was statistically significant(P<0.05).The difference in step speed and frequency between the frailty group and pre-frailty group were statistically significant(P<0.05).(4)Dual-task walking test: There were statistically significant differences in step speed and step length between pre-frailty and non-frailty(P<0.05).The differences in stride time,step speed,step frequency and step length between non-frailty and frailty were statistically significant(P<0.05).The differences in step length and step speed between frailty and pre-frailty were statistically significant(P<0.05).(5)In this study,between the dual task walking test and the natural normal walking test under different frailty states,the differences in stride time,step speed,step frequency and step length were statistically significant.Conclusion:(1)Elderly patients with type 2 diabetes have a high incidence of frailty.Among the 251 patients investigated,about 41.44% of the elderly are in the pre-frailty,and about 21.51 % of the elderly are in the frailty.(2)Compared with non-frailty patients,women is the risk factors in the pre-frailty.Fear of falling,women,high number of illnesses and high Hb A1 C levels are factors for frailty.(3)In the natural normal walking test,compared with the non-frailty group,the walking speed was slower,the walking frequency was less,and the step length was shorter in the pre-frailty.In the frailty group,the stride time was longer,the stride speed was slower,the step frequency was less and the step length was shorter.Compared with the pre-frailty,the frailty group walked more slowly and less frequently.(4)In the dual-task walking test,compared with the non-frailty group,the walking speed was slower,step length was shorter in the pre-frailty,the stride time was longer,the step speed was slower,the step frequency was less and the step length was shorter in the frailty.Compared with the pre-frailty,the frailty group walked more slowly and shorter length.(5)The gait characteristics of dual-task walking in different frailty states of the research object were worse than the natural normal speed.It is suggested that the addition of cognitive distracters during walking might interfere with the gait of the elderly.Therefore,the elderly should try to avoid excessive distraction to avoid accidents during walking. |
