Effects of integrated intrinsic foot muscle exercise with foot core training device on balance and body composition among community-dwelling adults aged 60 and above.

BACKGROUND: Evidence on the effects of plantar intrinsic foot muscle exercise in older adults remains limited. This study aimed to evaluate the effect of an integrated intrinsic foot muscle exercise program with a novel three-dimensional printing foot core training device on balance and body composition in community-dwelling adults aged 60 and above. METHODS: A total of 40 participants aged ≥ 60 years were enrolled in this quasi-experimental, single-group, pretest-posttest design; participants were categorized into two groups, those with balance impairment and those without balance impairment. The participants performed a 4-week integrated intrinsic foot muscle exercise program with a three-dimensional printing foot core training device. The short physical performance battery (SPPB) and timed up and go test were employed to evaluate mobility and balance. A foot pressure distribution analysis was conducted to assess static postural control. The appendicular skeletal muscle mass index and fat mass were measured by a segmental body composition monitor with bioelectrical impedance analysis. The Wilcoxon signed rank test was used to determine the difference before and after the exercise program. RESULTS: Among the 40 enrolled participants (median age, 78.0 years; female, 80.0%; balance-impaired group, 27.5%), the 95% confidence ellipse area of the center of pressure under the eyes-closed condition was significantly decreased (median pretest: 217.3, interquartile range: 238.4; median posttest: 131.7, interquartile range: 199.5; P = 0.001) after the exercise. Female participants without balance impairment demonstrated a significant increase in appendicular skeletal muscle mass index and a decrease in fat mass. Participants in the balance-impaired group exhibited a significant increase in SPPB. CONCLUSIONS: Integrated intrinsic foot muscle exercise with a three-dimensional printing foot core training device may improve balance and body composition in adults aged 60 and above.

Effects of integrated care with case management and nutritional counselling for frail older adults with nutritional risk in the primary care setting.

BACKGROUND: The effects of integrated care with case management and nutritional counselling for frail patients with nutritional risk are unclear. OBJECTIVES: To assess the impact of the integrated care model for frail patients with nutritional risk in the primary care setting. METHODS: This was a retrospective observational study. We enrolled 100 prefrail or frail patients according to Clinical Frailty Scale (CFS) aged ≥ 60 years with nutritional risk from the geriatric clinic. We implemented the frailty intervention model, including integrated care with comprehensive geriatric assessments (CGA), case management, and nutritional counselling by the dietitian. We obtained measures of CGA components, physical performance, body mass index (BMI), and daily caloric intake before and after the 2-month care program. We used the Wilcoxon signed-rank test to analyse differences after the care program and applied multiple linear regression to determine the predictive factors for CFS improvement. RESULTS: Among the 100 patients (mean age, 75.0 ±â€…7.2 years; females, 71.0%; frail patients, 26%), 93% improved their CFS status, and 91% achieved > 80% of recommended daily caloric intake after the care program. The Mini Nutritional Assessment Short-Form significantly improved after the program. BMI and daily caloric intake increased significantly after nutritional counselling. The post-test short physical performance battery (SPPB) significantly increased with a faster 4 m gait speed. Baseline poor CFS was a significant predictor for CFS improvement. CONCLUSIONS: Integrated care with case management and nutritional counselling for prefrail and frail patients with nutritional risk in the primary care setting may improve physical performance and nutritional status.

Frailty, a state of vulnerability in older adults, can lead to various health issues. Early intervention in poor nutrition can be beneficial in managing frailty. Integrated care with comprehensive assessments has demonstrated its effectiveness in managing frail older adults. However, there are limited models designed for primary care, and nutritional intervention alone may not be adequate. This retrospective observational study, conducted in a specialized primary care unit for geriatric patients, enrolled prefrail and frail individuals at nutritional risk. A multidisciplinary team implemented an integrated care model that included comprehensive geriatric assessments, case management, and nutritional counselling. After the care program, a significant majority of patients exhibited improved Clinical Frailty Scale status, along with a high proportion achieving 80% of their recommended daily caloric intake. The study also revealed improved physical performance measured by the Short Physical Performance Battery, and a faster 4 m gait speed. Additionally, both BMI and daily caloric intake significantly increased after nutritional counselling. These findings highlight the positive impact of integrated care, including comprehensive assessments, case management, and nutritional counselling, on the physical performance and nutritional status of prefrail and frail older adults.

The association of body mass index (BMI) with all-cause mortality in older Taiwanese: results of a national cohort study.

In older adults, underweight has been shown to be associated with increased all-cause mortality, but the association with excessive weight is inconclusive. The study aimed to determine the association of weight status with subsequent all-cause mortality risk in older Taiwanese. The study analyzed the dataset of the "Survey of Health and Living Status of the Elderly in Taiwan", a nationally representative longitudinal cohort study. Baseline BMI calculated from self-reported weight and height (kg/m(2)) was used to predict all-cause mortality risk during subsequent four years in 2462 ≥ 53 years old Taiwanese. Cox-regression analysis was performed to determine the significance of the association of weight status with all-cause mortality during follow-up four-years controlled for demographic, lifestyle and health-related variables. Results showed that underweight was associated with increased risk of mortality risk in all age ranges examined, but excessive weight was not significantly associated with increased risk of mortality. Results suggest that the association between BMI status and all-cause mortality is "L-shaped" and "obesity paradox" may indeed exist in these specific age groups in Taiwanese over 65 years old. However, some uncertainty remains because confounding factors could not be totally controlled. Large scale prospective studies with better control of confounding factors are needed to resolve this important public health issue.
