FACTORS RELATED TO POSTURAL CONTROL IN ELDERLY WITH TYPE-2 DIABETES MELLITUS
Elderly. Accident by Falls. Postural Balance. Diabetes Mellitus. Health Evaluation.
Introduction: Diabetes Mellitus (DM) has been a risk factor for other comorbidities in elderly due to functional abnormalities of the sensory, motor and autonomic systems which are exposed to uncontrolled carbohydrate metabolism and they may compromise the Postural Control (CP) in daily tasks, making them more susceptible to falls. Objectives: Assessing elderly patients with type-2 DM in relation to: 1) the clinical, functional, psycho-cognitive caracterization and postural control; 2) determining the sociodemographic, clinical, functional and psycho-cognitive factors, related to CP elderly with type-2 diabetes. Method: It comes to an analytical observational study of transversal nature which evaluated 58 female and male individuals, aged over 60 years. The CP was assessed using the Mini BESTest and the total score in percentage, analyzed in relation to other study variables. Mann-Whitney tests were applied, by Kruskal-Wallis test followed by Dunn's test and Spearman's correlation coefficient (ρ), p<0,05. Results: The sample showed a female majority (72.4%) with a mean age about 69.31 ± 6.95 years. The average number of diseases associated with DM was 3.26 ± 0.74 and the mean number of drugs was 6.26 ± 2.73. Many of the elderly have reported knowing the diagnosis of DM for more than five years (74.1%), the average glycated hemoglobin was 8.94 ± 2.43 (%). Most of them used insulintherapy (48.3%) and did not use motion device (94.8%) nor showed orthostatic hypotension (75.9%). They complained of pain in the lower limbs. For 41 (70.7%) of patients, the fear of falling was underlined and 38 (65.5%) reported a tendency to fall, although presenting lower risk of falls in the evaluation of mobility (60.3%). Dizziness was prevalent in 34 (58.6%) of the cases, the most predominant of the rotary type (34.5%). Lot of participants did not show cognitive impairment (56.9%) or showed depressive symptoms (60.3%). Median Mini BESTest was 79.06%. There were significant associations between the total score of the Mini BESTest and the categories of variables: age (p<0,001), education (p=0,024), general health (p = 0.002), regular physical activity (p=0.005) nervous system disorders (p = 0.004), respiratory system diseases (p <0.001), drugs used for nervous system (p <0.001), use of motion device (p <0.001), falls in the last year (p = 0.002), mobility and fall risk (p = 0.002), dizziness (p = 0.002) and kind of dizziness (p = 0.002). Statistically significant correlations were found between the score of the Mini BESTest and quantitative variables: number of diseases (ρ=-0.265; p = 0.004), hand grip strength (HGS) (ρ = 0.303; p = 0.021), Mini-Mental State Examination (MMSE) ( ρ = 0.324; p = 0.013) and Geriatric Depression Scale (ρ = -0.459; p <0.001). Conclusions: Postural Control in elderly with type-2 diabetes mellitus is more committed when associated with advancing age, low education, more diseases, worse general health, physical inactivity, poor strength in the dominant upper limb, presence of diseases of the nervous and respiratory systems, use of drugs to the nervous system, use of motion device, recurrent falls, impaired mobility and risk of falls, dizziness, association between the presence of vertigo and non-rotating, the cognitive impairment and depressive symptoms.
